Continuous Performance Validation | @CloudExpo #DevOps #IoT #BigData

Today, user experience is crucial to an application's success

Achieving Continuous Performance Validation with Synthetic Users

In most modern development groups, there's a big focus on creating code that works. The idea goes that in more traditional, waterfall approaches, errors in code that aren't fixed until late in the cycle are much more expensive to resolve due to unintended consequences. Today, some groups practice test-driven development as a way to ensure that code is always functional while others work with short agile sprints where all code produced must be usable in the field by the end of each sprint.

There's a common understanding about what it means for a coding task to be "done." Yet, often this "doneness" is only a measure of functionality - not necessarily usability.

Today, user experience is crucial to an application's success, and that goes well beyond what color your button is or how prominently a call-to-action is placed. Users leave your site if pages don't load fast enough or if the site simply feels sluggish when compared with your competitors' sites.

The question is: is there a process for validating that your app is performing up to your customers' expectations and have that process treat performance testing with the same amount of rigor as functional testing?

Yes. It's called Continuous Performance Validation.

Defining Continuous Performance Validation
Continuous Performance Validation is the process of continuously testing, monitoring and improving performance at every stage of the application development lifecycle, from development to production, utilizing automated and collaborative tooling.

The heart of this process is a set of performance test scenarios that sit alongside more traditional functional unit tests. These tests, in conjunction with performance SLAs that can be placed on the task board as inputs to the development process itself, give you a library of performance unit tests that you can mix and match in a number of interesting ways.

As the building blocks of Continuous Performance Validation, these elements let you form long chains of specific behavior to use as test scenarios, mimicking how users actually use your app. These transactions should be used in every phase of the application development lifecycle - development, pre-production, and production - to proactively test and monitor performance across environments.

Before code is released, these scenarios can be pieced together to analyze how load and stress impact your app in different ways. That information can be fed to Operations for infrastructure and capacity planning purposes. Meanwhile, in production, those same scenarios can be executed to see if performance trends in reality match what was predicted in test. Problems can be identified, sent back to dev & test so that issues can be patched quickly.

Synthetic Users: The Key to Continuity
Continuous Performance Validation depends on the idea of creating synthetic users that can move through the app just like real users. Throughout the synthetic users' journeys, they gather metrics on performance and the end user experience.

As part of your continuous integration process, you can continually validate the overall performance of the system by building automated scenarios and plugging them into various stages of the dev process, executed by synthetic users.

In development, synthetic users execute transactions through unit tests that can validate localized performance requirements of key systems. They can fulfill a pre-planned test requirement, similar to TDD, and they can protect against regressions as code changes.

In pre-production, synthetic users can be thrown out from the cloud for truly distributed and georealistic load testing across the entire system. These users traverse various paths through the application and help to define the scalability and geographical contours of your application's distributed user base.

In production, synthetic users operate alongside real users. They navigate the system and exercise the same user paths you have already tested. But instead of sending out millions of them, you only need to send out a few, which gather metrics about performance and availability at particular moments in time and tell you if there is going to be a problem. Synthetic users validate that your performance is up to par and give you insight as to where it is not.

Conclusion
Continuous Performance Validation is a powerful process for apps that need to perform. By putting it in place, you won't be treating performance as an afterthought. Performance testing will be directly integrated into your standard process of development, making performance part of everyone's job description and everyone's responsibility.

One of the biggest challenges with adopting a DevOps mentality is: new applications are easily adapted to cloud-native, microservice-based, or containerized architectures - they can be built for them - but old applications need complex refactoring. On the other hand, these new technologies can require relearning or adapting new, oftentimes more complex, methodologies and tools to be ready for production. In his general session at @DevOpsSummit at 20th Cloud Expo, Chris Brown, Solutions Marketing Manager at Nutanix, explored how Nutanix is bringing these sides together - agility for pets, governance for cattle - in a single unified platform. With this combined approach, Nutanix removes silos - both technological and human - propelling your applications to a new level.
Most of the time there is a lot of work involved to move to the cloud, and most of that isn't really related to AWS or Azure or Google Cloud. Before we talk about public cloud vendors and DevOps tools, there are usually several technical and non-technical challenges that are connected to it and that every company needs to solve to move to the cloud. In his session at 21st Cloud Expo, Stefano Bellasio, CEO and founder of Cloud Academy Inc., will discuss what the tools, disciplines, and cultural aspects are that enterprise companies are considering to get to the cloud and eventually transform the way they build software and services.

Kubernetes is an open source system for automating deployment, scaling, and management of containerized applications. Kubernetes was originally built by Google, leveraging years of experience with managing container workloads, and is now a Cloud Native Compute Foundation (CNCF) project. Kubernetes has been widely adopted by the community, supported on all major public and private cloud providers, and is gaining rapid adoption in enterprises. However, Kubernetes may seem intimidating and complex to learn. This is because Kubernetes is more of a toolset than a ready solution. Hence it’s essential to know when and how to apply the appropriate Kubernetes constructs.

New competitors, disruptive technologies, and growing expectations are pushing every business to both adopt and deliver new digital services. This ‘Digital Transformation’ demands rapid delivery and continuous iteration of new competitive services via multiple channels, which in turn demands new service delivery techniques – including DevOps. In this power panel at @DevOpsSummit 20th Cloud Expo, moderated by DevOps Conference Co-Chair Andi Mann, panelists examined how DevOps helps to meet the demands of Digital Transformation – including accelerating application delivery, closing feedback loops, enabling multi-channel delivery, empowering collaborative decisions, improving user experience, and ultimately meeting (and exceeding) business goals.
Cloud Expo, Inc. has announced today that Andi Mann and Aruna Ravichandran have been named Co-Chairs of @DevOpsSummit at Cloud Expo Silicon Valley which will take place Oct. 31-Nov. 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
