While Skylight was originally developed to instrument web requests, we understand the web interface is only one part of your server-side application. For this reason, we've been hard at work preparing Skylight for Background Jobs!

Cloud computing, containerization, and container orchestration are the most important trends in DevOps. Whether you’re a data scientist, software developer, or product manager, it’s good to know Docker and Kubernetes basics. Both technologies help you collaborate with others, deploy your projects, and increase your value to employers. In this article, we’ll cover essential Kubernetes concepts. There are a lot of Kubernetes terms, which can make it intimidating.

If you’re thinking about using containers to manage an application, there are a lot of options for technologies to use. It can be difficult to even know where to begin to make a decision.

In this post, we’ll share how Sentry wrote an experimentation system with minimal work.
