Optimize Kubernetes Performance Part 1: Cluster Configurations

Kubernetes is a powerful platform that comes with many features to help engineers run their applications more efficiently. However, as you gain more experience and deploy more workloads, you’ll inevitably start looking for ways to optimize Kubernetes performance. There are many ways to approach optimization. On one hand, you could work exclusively with the tools and configurations provided by Kubernetes itself; on the other, you could reap the benefits of third-party tools.

Testing Kubernetes Ingress with Production Traffic

Testing Kubernetes Ingress resources can be tricky, and can lead to frustration when bugs pop up in production that weren’t caught during testing. This can happen for a variety of reasons, but with Ingress specifically, it often has to do with a misalignment between the data used in testing and the traffic generated in production. Tools like Postman can be a great way of generating traffic, but they have the drawback of being manually created.

An Overview of Traffic Mirroring Options in Kubernetes

Testing in production carries a lot of risk, like possibly causing downtime for users. However, the advantages of using real user traffic are many, which has led to the popularity of traffic mirroring. Mirroring can be implemented as part of pre-deployment testing, as well as other parts of the developer experience like the development itself. But, how do you get started with it?

The Role of Traffic Replay in Production Traffic Replication

Testing in production is one of the most effective—and risky—ways of testing. The ability to use real-world conditions ensures reliability of tests, as no bugs can appear as a result of misconfigurations of the environment. However, using the same environment as your users also has an obvious downside: any bugs discovered by testing will immediately affect users.

Test Automation: Benefits and Use Cases

After spending hours or even days manually testing your software, you're wondering whether there's any way to optimize this process. Well, you're right to look toward implementing test automation. However, minimizing manual labor isn't the only valid reason to do so; there are many other benefits to test automation, a few being: Test automation is an entire field in itself that can help you improve accuracy and resilience, which you'll learn a lot more about throughout this post.

How to Get Started with Software Testing

You've forgotten to add frontend validation to number fields, and now people are getting an error when they enter text into those fields. However, this is an issue that's easily preventable-by implementing a proper test that checks for edge cases, but how do get started with software testing? Avoiding bugs in production is just one advantage of testing, it also helps you be more confident about your applications, opens up the potential for a full CI/CD pipeline, and much more. In this post, we'll introduce you to software testing, as well as provide pointers on how to move from beginner to advanced.

How Load Testing and Mocks Work Together

If you’ve worked with load testing before, you know that there are a lot of things to consider. Whether or not you should combine load testing and mocks is one of those considerations. Getting to the answer requires knowledge of your infrastructure and your development procedures, which will all influence what questions you need to ask yourself.

The Role of Kubernetes in Production Traffic Replication

Organizations are starting to realize that simply writing tests to generate traffic is simply not good enough. Rather, production traffic replication is now necessary, where you record traffic from your production environment and then replay it in your development environment. To match the modern principles of this testing methodology, it makes sense to also utilize modern infrastructure, like Kubernetes.

How to Create K6 Load Tests from API Recordings

Load testing is one of the most common ways to test the resiliency of your applications. In this blog we show how recording production data with Speedscale and exporting to a K6 load tests gives you the best of both worlds. Whether or not it's important for your organization, there are clear benefits to be had from implementing these types of tests. By doing so, you can: When it comes to load testing, two of the most modern tools are Speedscale and K6. While there are many reasons for choosing one over the other, there are also benefits to using them together. If you want to know what the main differences are, check out the in-depth comparison.
