Most of the communication on the Internet comes directly from the clients to the servers. The client usually sends a request, and the server responds to that request. It is known as a client-server model, and it works well in most cases. However, there are some scenarios in which the server needs to send messages […]
Focusing on Kubernetes security, we have to go through container security and their runtimes. All in all, clusters without containers running does not make much sense. Hardening workloads often is much harder than hardening the cluster itself. Let’s start with container configuration. Basic rules for containers There are two ways how you can get a […]
While researching how enterprises adopt Kubernetes, we can outline a common scenario; implementing a Kubernetes cluster in a company often starts as a proof of concept.
Currently, Vanilla Kubernetes supports 5000 nodes in a single cluster. It does not mean that we can just deploy 5000 workers without consequences – some problems and edge scenarios happen only in the larger clusters. In this article, we analyze the common Kubernetes failures at scale, the issues we can encounter if we reach a […]
Kubernetes cluster management can be demanding. This article helps you manage your cluster resources properly, especially in an autoscaling environment.
Let’s finish up the process of building our AWS infrastructure and discover the last crucial elements of the AWS Cloud needed for our highly available, secure and fault-tolerant cloud system. This article is the third and the last one of the mini-series which walks you through the process of creating an enterprise-level AWS infrastructure and […]
Let’s pick up the thread of our journey into the AWS Cloud, and keep discovering the intrinsics of the cloud computing universe while building a highly available, secure and fault-tolerant cloud system on the AWS platform.

Nowadays, we can observe many repetitive patterns in existing implementations. From microservices, to MVC layers, or REST APIs. Authorization and authentication are the fundamental parts of application security. The most popular pattern it the login and password, frequently with the addition of two-factor authentication via SMS code, e-mail or a software token. But the problem […]
