DevOps Requires APM | @DevOpsSummit @CAInc #DevOps #APM

Every IT organization bent on cloud excellence should make cloud APM an integral component of their DevOps environment

Much of the discussion around cloud DevOps focuses on the speed with which companies need to get new code into production. This focus is important - because in an increasingly digital marketplace, new code enables new value propositions. New code is also often essential for maintaining competitive parity with market innovators.

But new code doesn't just have to deliver the functionality the business requires. It also has to behave well because the behavior of code in the cloud affects performance, cost, reliability, and scalability. For developers to write code that behaves well, they need great cloud APM.

What Cloud APM Tells Cloud Developers
Most people think almost exclusively about what cloud APM tells cloud ops teams. After all, those ops teams need APM tools that empower them to quickly pinpoint performance bottlenecks and the root causes of application outages. With the right APM tools, cloud ops teams can rapidly resolve - and even proactively prevent - capacity issues that can adversely impact the user/customer experience.

Ops teams, however, don't modify code. They have to live with what developers produce. If code is written inefficiently, ops has no choice but to add provisioning as necessary to meet service-level objectives.

Developers, on the other hand, can fix bad code behaviors. The right cloud APM technology can tell them exactly what those behaviors are. In fact, the insights provided by APM tools are indispensable to any development team charged with writing excellent code.

Cloud APM, in other words, is the feedback loop that cloud developers need to ensure that DevOps is not only functionally Agile but also operationally excellent.

Completing the DevOps Loop

Of course, completing the cloud DevOps loop requires more than just a good APM tool. You also need processes that capture the problematic code behaviors discovered via APM and feed them into your software change management environment. These processes should include:

  • Clearly itemized code behavior issues. It's not enough just to tell developers their code is somehow inefficient. They need hard data on specific issues. Is a middleware workload getting triggered with surprising frequency? Are too many database threads being opened - while too few get closed? These specifics are essential for ensuring that developers apply their skills in ways that actually deliver value.
  • Well-managed issue prioritization/triage. A core aspect of Agile development is smart control of scope. In keeping with this scope control, DevOps teams need to make sure they appropriately prioritize code behavior issues based on how they impact cost and user experience.
  • Issue accountability. Once developers work on a code behavior issue, it's essential to monitor the results. Those results cumulatively drive learning that makes the whole process more effective and efficient - whether it's developers learning how to write better-behaving code or DevOps managers learning that some of the issues they tend to flag aren't code-related at all.

Organizations that leverage cloud APM in this way will significantly improve the quality and consistency of their end-user experience, while also achieving non-trivial reductions in cloud costs. Proactive attention to code behaviors also substantially mitigates the business risks associated with full-scale service outages.

For these reasons and more, every IT organization bent on cloud excellence should make cloud APM an integral component of their DevOps environment.

The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications. Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addresses many of the challenges faced by developers and operators as monolithic applications transition towards a distributed microservice architecture. A tracing tool like Jaeger analyzes what's happening as a transaction moves through a distributed system. Monitoring software like Prometheus captures time-series events for real-time alerting and other uses. Grafeas and Kritis provide security polic...
DevOpsSUMMIT at CloudEXPO will expand the DevOps community, enable a wide sharing of knowledge, and educate delegates and technology providers alike. Recent research has shown that DevOps dramatically reduces development time, the amount of enterprise IT professionals put out fires, and support time generally. Time spent on infrastructure development is significantly increased, and DevOps practitioners report more software releases and higher quality. Sponsors of DevOpsSUMMIT at CloudEXPO will benefit from unmatched branding, profile building and lead generation opportunities.
