The Delicate Dance: A Web of Services and Hidden Culprits

Modern user experiences that leverage real-time data rely on complex chains of interdependent services – a delicate dance of microservices, databases, messaging platforms, and virtualized compute infrastructure. A malfunction in any one element can create a ripple effect, impacting the freshness and availability of data for users. This translates to frustrating delays, lags, or even complete UX failures.

Let’s delve into the hidden culprits behind these issues and see how seemingly minor bottlenecks can snowball into major UX problems:

Slowdown Domino with Degraded Microservice

• Scenario: A microservice responsible for product recommendations experiences high latency due to increased user traffic and internal performance degradation (e.g., memory leak, code inefficiency).
• Impact 1: The overloaded and degraded microservice takes significantly longer to process requests and respond to the database.
• Impact 2: The database, waiting for the slow microservice response, experiences delays in retrieving product information.
• Impact 3: Due to the degradation, the microservice might also have issues sending messages efficiently to the message queue. These messages contain updates on product availability, user preferences, or other relevant data for generating recommendations.
• Impact 4: Messages pile up in the queue due to slow processing by the microservice, causing delays in delivering updates to other microservices responsible for presenting information to the user.
• Impact 5: The cache, not receiving timely updates from the slow microservice and the message queue, relies on potentially outdated data.
• User Impact: Users experience significant delays in seeing product recommendations. The recommendations themselves might be inaccurate or irrelevant due to outdated data in the cache, hindering the user experience and potentially leading to missed sales opportunities. Additionally, users might see inconsistencies between product information displayed on different pages (due to some parts relying on the cache and others waiting for updates from the slow microservice).

Message Queue Backup

• Scenario: A sudden spike in user activity overwhelms the message queue handling communication between microservices.
• Impact 1: Messages pile up in the queue, causing delays in communication between microservices.
• Impact 2: Downstream microservices waiting for messages experience delays in processing user actions.
• Impact 3: The cache, not receiving updates from slow microservices, might provide outdated information.
• User Impact: Users experience lags in various functionalities – for example, slow loading times for product pages, delayed updates in shopping carts, or sluggish responsiveness when performing actions.

Cache Miss Cascade

• Scenario: A cache experiences a high rate of cache misses due to frequently changing data (e.g., real-time stock availability).
• Impact 1: The microservice needs to constantly retrieve data from the database, increasing the load on the database server.
• Impact 2: The database, overloaded with requests from the cache, experiences performance degradation.
• Impact 3: The slow database response times further contribute to cache misses, creating a feedback loop.
• User Impact: Users experience frequent delays as the system struggles to retrieve data for every request, leading to a sluggish and unresponsive user experience.

Kubernetes Lag

• Scenario: A resource bottleneck occurs within the Kubernetes cluster, limiting the processing power available to microservices.
• Impact 1: Microservices experience slow response times due to limited resources.
• Impact 2: Delays in microservice communication and processing cascade throughout the service chain.
• Impact 3: The cache might become stale due to slow updates, and message queues could experience delays.
• User Impact: Users experience lags across various functionalities, from slow page loads and unresponsive buttons to delayed updates in real-time data like stock levels or live chat messages.

Even with advanced monitoring tools, pinpointing the root cause of these and other issues can be a time-consuming detective hunt. The triage & troubleshooting process often requires a team effort, bringing together experts from various disciplines. Together, they sift through massive amounts of observability data – traces, metrics, logs, and the results of diagnostic tests – to piece together the evidence and draw the right conclusions so they can accurately determine the cause and effect. The speed and accuracy of the process is very much determined by the skills of the available resources when issues arise

Only when the root cause is understood can the responsible team make informed decisions to resolve the problem and restore reliable service.

Transforming Incident Response: Automation of the Triage & Troubleshooting Process

Traditional methods of incident response, often relying on manual triage and troubleshooting, can be slow, inefficient, and prone to human error. This is where automation comes in, particularly with the advancements in Artificial Intelligence (AI). Specifically, a subfield of AI called Causal AI presents a revolutionary approach to transforming incident response.

Causal AI goes beyond correlation, directly revealing cause-and-effect relationships between incidents and their root causes. In an environment where services rely on real-time data and fast resolution is critical, Causal AI offers significant benefits:

• Automated Triage: Causal AI analyzes alerts and events to prioritize incidents based on severity and impact. It can also pinpoint the responsible teams, freeing resources from chasing false positives.
• Machine Speed Root Cause Identification: By analyzing causal relationships, Causal AI quickly identifies the root cause, enabling quicker remediation and minimizing damage.
• Smarter Decisions: A clear understanding of the causal chain empowers teams to make informed decisions for efficient incident resolution.

Causely is leading the way in applying Causal AI to incident response for modern cloud-native applications. Causely’s technology utilizes causal reasoning to automate triage and troubleshooting, significantly reducing resolution times and mitigating business impact. Additionally, Causal AI streamlines post-incident analysis by automatically documenting the causal chain.

Beyond reactive incident response, Causal AI offers proactive capabilities that focus on measures to reduce the probability of future incidents and service disruptions, through improved hygiene, predictions and “what if” analysis.

The solution is built for the modern world that incorporates real-time data, applications that communicate synchronously and asynchronously, and leverage modern cloud building blocks (databases, caching, messaging & streaming platforms and Kubernetes).

This is just the beginning of the transformative impact Causal AI is having on incident response. As the technology evolves, we can expect even more advancements that will further streamline and strengthen organizations’ ability to continuously assure the reliability of applications.

Can AI-powered causality crack the RCA code for cloud-native applications?

The idea of applying AI to determine causality in an automated Root Cause Analysis solution sounds like the Holy Grail, but it’s easier said than done. There’s a lot of misinformation surrounding RCA solutions. This article cuts the confusion and provides a clear picture. I will outline the essential functionalities needed for automated root cause analysis. Not only will I define these capabilities, I will also showcase some examples to demonstrate their impact.

By the end, you’ll have a clearer understanding of what a robust RCA solution powered by causal AI can offer and how it can empower your IT team to better navigate the complexities of your cloud-native environment and most importantly dramatically reduce MTTx.

The Rise (and Fall) of the Automated Root Cause Analysis Holy Grail

Modern organizations are tethered to technology. IT systems, once monolithic and predictable, have fractured into a dynamic web of cloud-native applications. This shift towards agility and scalability has come at a cost: unprecedented complexity.

Troubleshooting these intricate ecosystems is a constant struggle for DevOps teams. Pinpointing the root cause of performance issues and malfunctions can feel like navigating a labyrinth – a seemingly endless path of interconnected components, each with the potential to be the culprit.

For years, automating Root Cause Analysis (RCA) has been the elusive “Holy Grail” for service assurance, as the business consequences of poorly performing systems are undeniable, especially as organizations become increasingly reliant on digital platforms.

Despite its importance, commercially available solutions for automated RCA remain scarce. While some hyperscalers and large enterprises have the resources and capital to attempt to develop in-house solutions to address the challenge (like Capital One’s example), these capabilities are out of reach for most organizations.

Beyond Service Status: Unraveling the Cause-and-Effect Relations in Cloud Native Applications

Highly distributed systems, regardless of technology, are vulnerable to failures that cascade and impact interconnected components. Cloud-native environments, due to their complex web of dependencies, are especially prone to this domino effect. Imagine a single malfunction in a microservice, triggering chain reaction, disrupting related microservices. Similarly, a database issue can ripple outwards, affecting its clients and in turn everything that relies on them.

The same applies to infrastructure services like Kubernetes, Kafka, and RabbitMQ. Problems in these platforms might not always be immediately obvious because of the symptoms they cause within their domain. Furthermore symptoms manifest themselves within applications they support. The problem can then propagate further to related applications, creating a situation where the root cause problem and the symptoms they cause are separated by several layers.

Although many observability tools offer maps and graphs to visualize infrastructure and application health, these can become overwhelming during service disruptions and outages. While a sea of red icons in a topology map might highlight one or more issues, they fail to illuminate cause-and-effect relationships. Users are then left to decipher the complex interplay of problems and symptoms to work out the root cause. This is even harder to decipher when multiple root causes are present that have overlapping symptoms.

While topology maps show the status of services, they leave their users to interpret cause & effect

In addition to topology based correlation, DevOps team may also have experience of other types of correlation including event deduplication, time based correlation and path based analysis all of which attempt to reduce the noise in observability data. Don’t loose sight of the fact that this is not root cause analysis, just correlation, and correlation does not equal causation. This subject is covered further in a previous article I published Unveiling The Causal Revolution in Observability.

The Holy Grail of troubleshooting lies in understanding causality. Moving beyond topology maps and graphs, we need solutions that represent causality depicting the complex chains of cause-and-effect relationships, with clear lines of responsibility. Precise root cause identification that clearly explains the relationship between root causes and the symptoms they cause, spanning the technology domains that support application service composition, empowers DevOps teams to:

• Accelerate Resolution: By pinpointing the exact source of the issue and the symptoms that are caused by this, responsible teams are notified instantly and can prioritize fixes based on a clear understanding of the magnitude of the problem. This laser focus translates to faster resolution times.
• Minimize Triage: Teams managing impacted services are spared the burden of extensive troubleshooting. They can receive immediate notification of the issue’s origin, impact, and ownership, eliminating unnecessary investigation and streamlining recovery.
• Enhance Collaboration: With a clear understanding of complex chains of cause-and-effect relationships, teams can collaborate more effectively. The root cause owner can concentrate on fixing the issue, while impacted service teams can implement mitigating measures to minimize downstream effects.
• Automate Responses: Understanding cause and effect is also an enabler for automated workflows. This might include automatically notifying relevant teams through collaboration tools, notification systems and the service desk, as well as triggering remedial actions based on the identified problem.

Bringing This To Life With Real World Examples

The following examples will showcase the concept of causality relations, illustrating the precise relationships between root cause problems and the symptoms they trigger in interrelated components that make up application services.

This knowledge is crucial for several reasons. First, it allows for targeted notifications. By understanding the cause-and-effect sequences, the right teams can be swiftly alerted when issues arise, enabling faster resolution. Second, service owners impacted by problems can pinpoint the responsible parties. This clarity empowers them to take mitigating actions within their own services whenever possible and not waste time troubleshooting issues that fall outside of their area of responsibility.

Infra Problem Impacting Multiple Services

In this example, a CPU congestion in a Kubernetes Pod is the root cause and this causes symptoms –  high latency – in application services that it is hosting. In turn, this results in high latency on other applications services. In this situation the causal relationships are clearly explained.

A Microservice Hiccup Leads to Consumer Lag

Imagine you’re relying on a real-time data feed, but the information you see is outdated. In this scenario, a bug within a microservice (the data producer) disrupts its ability to send updates. This creates a backlog of events, causing downstream consumers (the services that use the data) to fall behind. As a result, users/customers end up seeing stale data, impacting the overall user experience and potentially leading to inaccurate decisions. Very often the first time DevOps find out about these types of issues is when end users and customers complain about the service experience.

Database Problems

In this example the clients of a database are experiencing performance issues because one of the clients is issuing queries that are particularly resource-intensive. Symptoms of this include:

• Slow query response times: Other queries submitted to the database take a significantly longer time to execute.
• Increased wait times for resources: Applications using the database experience high error rate as they wait for resources like CPU or disk access that are being heavily utilized by the resource-intensive queries.
• Database connection timeouts: If the database becomes overloaded due to the resource-intensive queries, applications might experience timeouts when trying to connect.

Summing Up

Cloud-native systems bring agility and scalability, but troubleshooting can be a nightmare. Here’s what you need to conquer Root Cause Analysis (RCA) in this complex world:

• Automated Analysis: Move beyond time-consuming manual RCA. Effective solutions automate data collection and analysis to pinpoint cause-and-effect relationships swiftly.
• Causal Reasoning: Don’t settle for mere correlations. True RCA tools understand causal chains, clearly and accurately explaining “why” things happen and the impact that they have.
• Dynamic Learning: Cloud-native environments are living ecosystems. RCA solutions must continuously learn and adapt to maintain accuracy as the landscape changes.
• Abstraction: Cut through the complexity. Effective RCA tools provide a clear view, hiding unnecessary details and highlighting crucial troubleshooting information.
• Time Travel:Post incident analysis requires clear explanations. Go back in time to understand “why” problems and understand the impact they had.

As organizations transform their IT applications and adopt cloud-native architectures, scaling seamlessly while minimizing resource overheads becomes critical. DevOps teams can play a pivotal role in achieving this by embracing automation across various facets of the service delivery process.

Automation shines in areas such as infrastructure provisioning and scaling, continuous integration and delivery (CI/CD), testing, security and compliance, but the practice of automated root cause analysis remains elusive.

While automation aids observability data collection and data correlation, understanding the relationships between cause and effect still requires the judgment and expertise of skilled personnel. This work falls on the shoulders of developers and SREs who have to manually decode the signals – from metrics, traces and logs – in order to get to the root cause when the performance of services degrades.

Individual incidents can take hours and even days to troubleshoot, demanding significant resources from multiple teams. The consistency of the process can also vary greatly depending on the skills that are available when these situations occur.

Service disruptions can also have significant financial consequences. Negative customer experiences directly impact revenue, and place an additional resource burden on the business functions responsible for appeasing unhappy customers. Depending on the industry you operate in and the type of services you provide, service disruptions may result in costly chargebacks and fines, making mitigation even more crucial.

Quantifying the load of manual root cause analysis on IT teams

Shining a Light on the Root Cause Analysis Problem in DevOps

While decomposing applications into microservices through the adoption of cloud-native architectures has enabled DevOps teams to increase the velocity with which they can release new functionality, it has also created a new set of operational challenges that have a significant impact on ongoing operational expenses and service reliability.

Increased complexity: With more services comes greater complexity, more moving parts, and more potential interactions that can lead to issues. This means diagnosing the root cause of problems becomes more difficult and time-consuming.

Distributed knowledge: In cloud-native environments, knowledge about different services often resides in different teams, who have limited knowledge of the wider system architecture. As the number of services scales, finding the right experts and getting them to collaborate on troubleshooting problems becomes more challenging. This adds to the time and effort required to coordinate and carry out root cause analysis and post incident analysis.  

Service proliferation fuels troubleshooting demands: Expanding your service landscape, whether through new services or simply additional instances, inevitably amplifies troubleshooting needs which translate into more resource requirements in DevOps teams for troubleshooting overtime.

Testing regimes cannot cover all scenarios: DevOps, with its CI/CD approach, releases frequent updates to individual services. This agility can reveal unforeseen interactions or behavioral changes in production, leading to service performance issues. While rollbacks provide temporary relief, identifying the root cause is crucial. Traditional post-rollback investigations might fall short due to unreproducible scenarios. Instead, real-time root cause analysis of these situations as they happen is important to ensure swift fixes and prevent future occurrences.

Telling the Story with Numbers

As cloud-native services scale, troubleshooting demands also grow exponentially, in a similar way to compounding interest on a savings account. As service footprints expand, more DevOps cycles are consumed by troubleshooting versus delivering new code, creating barriers to innovation. Distributed ownership and unclear escalation paths can also mask the escalating time that is consumed by troubleshooting. 

Below is a simple model that can be customized with company-specific data to illustrate the challenge in numbers. This model helps paint a picture of the current operational costs associated with troubleshooting. It also demonstrates how these are going to escalate over time, driven by the growth in cloud-native services (more microservices, serverless functions, etc).   

The model also illustrates the impact of efficiency gains through automation versus the current un-optimized state. The gap highlights the size of the opportunity available to create more cycles for productive development while reducing the need for additional headcount into the future, by automating troubleshooting.

This model illustrates the costs and impact of efficiency gains that can be achieved through automated root cause analysis

Beyond the cost of human capital, there are a number of other costs that have a direct impact on troubleshooting costs. These include the escalating costs of infrastructure and third-party SaaS services, dedicated to the management of observability data. These are well publicized and highlighted in a recent article published by Causely Founding Engineer Endre Sara that discusses avoiding the pitfalls of escalating costs when building out Causely’s own SaaS offering.

While DevOps have a cost, they pale in comparison to the financial consequences of service disruptions. With automated root cause analysis, DevOps teams can mitigate these risks, saving the business time, money and reputation. 

Future iterations of the model will account for these additional dimensions. 

If you would like to put your data to work and see the quantifiable benefits of automated root cause analysis in numbers, complete the short form to get started. 

Translating Theory into Reality

Did you know companies like Meta and Capital One automate root cause analysis in devops, achieving 50% faster troubleshooting? However, the custom solutions built by these industry giants require vast resources and deep expertise in data science to build and maintain, putting automated root cause analysis capabilities out of reach for most companies.

The team at Causely are changing this dynamic. Armed with decades of experience –  applying AI to the management of distributed systems, networks, and application resource management – they offer a powerful SaaS solution that removes the roadblocks to automated root cause analysis in DevOps environments. The Causely solution enables

• Simplified post-incident analysis: All of the knowledge about the cause and effect of prior problems is stored and available to simplify the process of post incident analysis and learning.

Wrapping Up

In this article we discussed the key challenges associated with troubleshooting and highlighted the cost implications of today’s approach. Addressing these issues is important because the business consequences of today’s approach are significant.

1. Troubleshooting is costly because it consumes the time of skilled resources.
2. Troubleshooting steals time from productive activities which impacts the ability of DevOps to deliver new capabilities.

Modernization Of The RCA Process

Over the past month, I have spent a significant amount of time researching what vendors and customers are doing in the devops space to streamline the process of root cause analysis (RCA).

My conclusion is that the underlying techniques and processes used in operational environments today to perform RCA remain human centric. As a consequence troubleshooting remains complex, resource intensive and requires skilled practitioners to perform the work.

So, how do we break free from this human bottleneck? Brace yourselves for a glimpse into a future powered by AI. In this article, we’ll dissect the critical issues, showcase how cutting-edge AI advancements can revolutionize RCA, and hear first hand from operations and engineering leaders who have shared their perspective on this transformative tech, having experienced the capabilities first hand.

Troubleshooting In The Cloud Native Era With Monitoring & Observability

Troubleshooting is hard because when degradations or failures occur in components of a business service, they spread like a disease to related service entities which also become degraded or fail.

This problem is amplified in the world of cloud-native applications where we have decomposed business logic into many separate but interrelated service entities. Today an organization might have hundreds or thousands of interrelated service entities (micro services, databases, caches, messaging…).

To complicate things even further, change is a constant – code changes, fluctuating demand patterns, and the inherent unpredictability of user behavior. These changes can result in service degradations or failures.

Testing for all possible permutations in this ever-shifting environment is akin to predicting the weather on Jupiter – an impossible feat – amplifying the importance of a fast, effective and consistent root cause analysis process, to maintain the availability, performance and operational resilience of business systems.

While observability tools have made strides in data visualization and correlation, their inherent inability to explain the cause-and-effect relationships behind problems leaves us dependent on human expertise to navigate the vast seas of data to determine the root cause of service degradation and failures.

This dependence becomes particularly challenging due to siloed devops teams that have responsibility for supporting individual service entities within the complex web of services entities that make up business services. In this context individual teams may frequently struggle to pinpoint the source of service degradation or failure as the entity they support might be the culprit, or a victim of another service entity’s malfunction.

The availability of knowledge and skills within these teams also fluctuate due to business priorities, vacations, holidays, and even the daily working cycles. This resource variability can lead to significant inconsistencies in problem identification and resolution times.

Causal AI To The Rescue: Automating The Root Cause Analysis Process For Cloud Native DevOps

For those who are not aware, Causal AI is a distinct field in Artificial Intelligence. It is already used extensively in many different industries but until recently there has been no application of the technology in the world of devops.

Causely is a new pioneer championing the use of Causal AI working in the area of cloud-native applications. Their platform embodies an understanding of causality so that when service entities are degraded or failing and affecting other service entities that make up business services, it can explain the cause and effect, by showing the relationship between the problem and the symptoms that this causes.

Through this capability, the team with responsibility for the failing or degraded service can be immediately notified and get to work on resolving the problem. Other teams might also be provided with notifications to let them know that their services are affected, along with an explanation for why this occurred. This eliminates the need for complex triage processes that would otherwise involve multiple teams and managers to orchestrate the process.

Understanding the cause-and-effect relationships in software systems serves as an enabler for automated remediation, predictive maintenance, and planning/gaming out operational resilience.

By using software in this way to automate the process of root cause analysis, organizations can reduce the time and effort and increase the consistency in the troubleshooting process, all of which leads to lower operational costs, improved service availability and less business disruption.

OpenTelemetry and the Path to Understanding Complex Systems

Decades ago, the IETF’s (Internet Engineering Task Force) developed an innovative protocol, SNMP, revolutionizing network management. This standardization spurred a surge of innovation, fostering a new software vendor landscape dedicated to streamlining operational processes in network management, encompassing Fault, Configurations, Accounting, Performance, and Security (FCAPS). Today, SNMP reigns as the world’s most widely adopted network management protocol.

On the cusp of a similar revolution stands the realm of application management. For years, the absence of management standards compelled vendors to develop proprietary telemetry for application instrumentation, to enable manageability. Many of the vendors also built applications to report on and visualize managed environments, in an attempt to streamline the processes of  incident and performance management.

OpenTelemetry‘s emergence is poised to transform the application management market dynamics in a similar way by commoditizing application telemetry instrumentation, collection, and export methods. Consequently, numerous open-source projects and new companies are emerging, building applications that add value around OpenTelemetry.

This evolution is also compelling established vendors to embrace OpenTelemetry. Their futures hinge on their ability to add value around this technology, rather than solely providing innovative methods for application instrumentation.

Adding Value Above OpenTelemetry

While OpenTelemetry simplifies the process of collecting and exporting telemetry data, it doesn’t guarantee the ability to pinpoint the root cause of issues. This is because understanding the causal relationships between events and metrics requires more sophisticated analysis techniques.

Common approaches to analyzing OpenTelemetry data that get devops teams closer to this goal include:

• Visualization and Dashboards: Creating effective visualizations and dashboards is crucial for extracting insights from telemetry data. These visualizations should present data in a clear and concise manner, highlighting trends, anomalies, and relationships between metrics.
• Correlation and Aggregation: To correlate logs, metrics, and traces, you need to establish relationships between these data streams. This can be done using techniques like correlation IDs or trace identifiers, which can be embedded in logs and metrics to link them to their corresponding traces.
• Pattern Recognition and Anomaly Detection: Once you have correlated data, you can apply pattern recognition algorithms to identify anomalies or outliers in metrics, which could indicate potential issues. Anomaly detection tools can also help identify sudden spikes or drops in metrics that might indicate performance bottlenecks or errors.
• Machine Learning and AI: Machine learning and AI techniques can be employed to analyze telemetry data and identify patterns, correlations, and anomalies that might be difficult to detect manually. These techniques can also be used to predict future performance or identify potential issues before they occur.

While all of these techniques might help to increase the efficiency of the troubleshooting process, human expertise is still essential for interpreting and understanding the results. This is because these approaches to analyzing telemetry data are based on correlation and lack an inherent understanding of cause and effect (causation).

Avoiding The Correlation Trap: Separating Coincidence from Cause and Effect

In the realm of analyzing observability data, correlation often takes center stage, highlighting the apparent relationship between two or more variables. However, correlation does not imply causation, a crucial distinction that software-driven causal analysis can effectively address and results in a better outcome in the following ways:

Operational Efficiency And Control: Correlation-based approaches often leave us grappling with the question of “why,” hindering our ability to pinpoint the root cause of issues. This can lead to inefficient troubleshooting efforts, involving multiple teams in a devops environment as they attempt to unravel the interconnectedness of service entities.

Software-based causal analysis empowers us to bypass this guessing game, directly identifying the root cause and enabling targeted corrective actions. This not only streamlines problem resolution but also empowers teams to proactively implement automations to mitigate future occurrences. It also frees up the time of experts in the devops organizations to focus on shipping features and working on business logic.

Consistency In Responding To Adverse Events: The speed and effectiveness of problem resolution often hinge on the expertise and availability of individuals, a variable factor that can delay critical interventions. Software-based causal analysis removes this human dependency, providing a consistent and standardized approach to root cause identification.

This consistency is particularly crucial in distributed devops environments, where multiple teams manage different components of the system. By leveraging software, organizations can ensure that regardless of the individuals involved, problems are tackled with the same level of precision and efficiency.

Predictive Capabilities And Risk Mitigation: Correlations provide limited insights into future behavior, making it challenging to anticipate and prevent potential problems. Software-based causal analysis, on the other hand, unlocks the power of predictive modeling, enabling organizations to proactively identify and address potential issues before they materialize.

This predictive capability becomes increasingly valuable in complex cloud-native environments, where the interplay of numerous microservices and data pipelines can lead to unforeseen disruptions. By understanding cause and effect relationships, organizations can proactively mitigate risks and enhance operational resilience.

Conclusion

OpenTelemetry marks a significant step towards standardized application management, laying a solid foundation for a more comprehensive understanding of complex systems. However, to truly unlock the full potential, the integration of software-driven causal analysis, also referred to as Causal AI, is essential. By transcending correlation, software-driven causal analysis empowers devops  organizations to understand cause and effect of system behavior, enabling proactive problem detection, predictive maintenance, operational risk mitigation and automated remediation.

The founding team of Causely participated in the standards-driven transformation that took place in the network management market more than two decades ago at a company called SMARTS. The core of their solution was built on Causal AI. SMARTS became the market leader of Root Cause Analysis in networks and was acquired by EMC in 2005. The team’s rich experience in Causal AI is now being applied at Causely, to address the challenges of managing cloud native applications.

Causely’s embrace of OpenTelemetry stems from the recognition that this standardized approach will only accelerate the advancement of application management. By streamlining telemetry data collection, OpenTelemetry creates a fertile ground for Causal AI to flourish.
