Deployment strategies affect everyone, no matter whether we are focused only on a single aspect of the application lifecycle or we are in full control. The way we deploy affects the architecture, testing, monitoring, and many other aspects. And not only that, but we can say that architecture, testing, and monitoring affect the way we deploy. All those things are closely related and affect each other.
We’ll discuss different deployment strategies and answer a couple of questions. Is your application stateful or stateless? Does its architecture permit scaling? How do you roll back? How do you scale up and down? Do you need your application to run always? Should you use Kubernetes Deployments instead of, let’s say, StatefulSets? Answers to those questions will not serve much unless we are familiar with some of the most commonly used deployment strategies. Not only that knowledge will help us choose which one to pick, but they might even influence the architecture of our applications.

What is the proxy design pattern in Java? The object oriented Proxy Design Pattern is a structural design pattern which is concerned with how classes and objects compose to form larger structures. The proxy design pattern in java takes a similar approach by providing a proxy object that acts as a placeholder for another object. Commonly a proxy is a class that functions as an interface to something else. The proxy design pattern can be best understood with the help of a real-world example
