Kubernetes adoption survey executive summary. Modern, cloud-native computing is impossible to separate from containers and Kubernetes adoption. While Kubernetes is still a relatively young technology, a large majority of global enterprises use it to run business-critical applications in production. The rapid adoption is driven—and challenged by—an ever-growing ecosystem of Kubernetes technologies that add advanced platform features, such as security, microservice communications, observability, s

Code coverage is a software quality metric commonly used during the development process that let’s you determine the degree of code that has been tested (or executed). To achieve optimal code coverage, it is essential that the test implementation (or test suites) tests a majority percent of the implemented code. There are a number of code coverage tools for languages like Java, C#, JavaScript, etc.

Note: on many contemporary systems the page size is 4KiB, but this is actually configurable for many architectures. The trade offs probably require a separate post.
