Rapid microservices development with Signadot

While developing microservices locally is possible, running and testing them in a production-like Kubernetes environment is complex. A typical development workflow while developing service in Kubernetes can significantly slow you down - from building a Docker image, pushing it, restarting the deployments, and testing the changes in a shared cluster. And all that, assuming you manage to keep the shared cluster up to date! In this article, I'll look at a tool called Signadot. Signadot introduces a concept of sandboxes that allow you to considerably shorten your developer workflow and go from minutes to mere seconds! The sandbox concept will enable you to build and run a service locally using the upstream and downstream dependencies inside a shared cluster.

You might want to use sticky sessions if your service is doing an expensive operation on first request, but later caching the value. That way, if the same user makes the request, the expensive operation will not be performed and value from the cache will be used.
