A container is a separate unit of software that encapsulates the software and libraries of an application, including its dependencies and its code. As a means of developing and managing stable applications, many organisations are adopting containers. Millions of applications currently use Docker, one of the most useful tools in this space. A Docker container can be used to build, run, inspect, and manage container images for developing applications.
Want to deploy a Rails app with Docker and AWS, but not sure where to start? AWS Fargate simplifies the convoluted process of deploying Docker on Amazon's Elastic Container Service (ECS). It's also a good alternative to Heroku.
In this Postman load testing tutorial, you'll learn how to run a large scale load test in Kubernetes using your existing Postman collections. Because HTTP services don't have a graphical user interface, it's common to build collections of requests using Postman during the development process. These collections are useful for running quick functionality tests as you develop each endpoint. However, as the service grows you eventually need to test it in a more realistic way with larger volume. This is called a load or stress test. Speedscale is a Production Data Simulation Platform that includes this stress/load testing capability out of the box.
Kubernetes is both revolutionary and “diffusionary.” It is a complete restructuring demanding a whole new slew of companion and support tools to cover and prop up the entire ecosystem. There are literally hundreds of tools – both open-source and proprietary – designed specifically with k8s in mind.
