In order to ensure the operability of microservices, to simplify their management, and most importantly, to isolate them from each other, they are “packed” into containers. A container is a shell that contains everything you need to successfully launch and operate a specific microservice. Several different containers can run under the same operating system, but each of them works with its own software libraries and dependencies. Failure of one container does not have any consequences for others, and it can be restarted almost instantly on another server in the cluster.

To optimize and automate the process of managing containers, special software is used – an orchestrator.

World practice shows that when developing web applications today it is advisable to use a cloud-native approach using complex products for working with containers. Therefore, right now you need to think about how your company develops, implements and maintains all business systems. Today, Kubernetes has become almost the industry standard for launching containerized microservices – the rest of the players occupy only certain narrow niches, their percentage is very small.

A Kubernetes-based solution has become extremely popular over the past few years due to its wide customization capabilities. In addition, Kubernetes can be configured and run on almost any hardware platform: bare-metal, virtual machines, and in the cloud.

For a long time, I’ve been writing JavaScript code without fully understanding how it works under the hood. Basically, in order to code in JavaScript, you don’t need to know how it works from the inside, but it will make your code better and allow you to look at some things in the language from a different angle.

All JavaScript code is executed in a single thread, which means that only one thing can be processed at a time. On the one hand, this is a useful limitation, since it allows us not to think about the specifics of working with parallelism. On the other hand, we must constantly monitor the code and make sure that synchronous operations (infinite loops, requesting data over the network) do not block our thread.

In most browsers, each tab has its own event loop, this allows you to isolate the tabs from each other, and if one hangs, the others will continue to work. Otherwise, one hung operation could break the entire browser across all tabs.

In fact, the environment can simultaneously manage a large number of “event loops” to process API requests. WebWorkers also have their own event loop.

A JavaScript developer must be aware that his code is always executed in the same event loop, and be careful not to block it.

Blocking Event Loop

Any code that takes a long time to execute before returning control to the main thread will block the execution of any JavaScript code on the page. This also blocks the user interface, and the user cannot interact with it (click, scroll the page, etc.).

Almost all I / O operations in JavaScript are non-blocking – network requests, file system operations in Node.js, etc. The exception is blocking operations, which is why callbacks are so popular in JavaScript, and more recently all they are starting to use Promise and async / await more often.
