Docker Swarm vs. Kubernetes

The advantages of container technology are minimizing the load of managing and deploying multifaceted applications. Containers put all essential dependencies in one set. They are easily manageable, secure, fast, portable, and scalable, which makes them the main choice over conventional VMs. To scale, you require a container orchestration tool to manage multiple containers. These days, […]

Docker Security

Docker Security issues fall under the broader umbrella of container security. However, in swarm mode, Docker also acts as the orchestrator. This article will focus on container security when using Docker. A follow-on article will look at Docker as the orchestration layer in swarm mode and what security concerns you’ll need to worry about. Components […]

Kubernetes Security

Kubernetes is an open-source system for managing containerized applications across a cluster of nodes. Kubernetes has gained immense popularity in recent years, and for a good reason – it’s an incredibly powerful tool. But with great power comes great responsibility, and as more and more businesses adopt Kubernetes, the need for good Kubernetes security practices […]

OpenStack Architecture 101

OpenStack is an open-source software cloud computing infrastructure platform. It is a free and open-source platform released under the Apache 2 License. OpenStack architecture consists of several software components that provide Infrastructure as a Service (IaaS). These co-operative components are organized into five main groups: compute, storage, networking, identity, and dashboard. What is OpenStack Architecture? […]

An Introduction to Kubernetes Architecture

If you’re a developer, then there’s a good chance you’ve heard of Kubernetes. But what is it, exactly? Kubernetes is a system for managing containerized applications, and it’s become one of the most popular tools in the DevOps toolbox. In this article, we’ll give you an introduction to Kubernetes architecture. What is Kubernetes? Kubernetes is […]

Advantages of Microservices

Microservices are all the talk these days. But what exactly are they, and why is it important? In short, microservices are software architecture in which large applications are decomposed into smaller, more manageable pieces called services. Each service is self-contained and can be deployed, managed, and scaled independently. The advantages of microservices allow for much […]

Docker Overview

Docker is an open-source project that automates the deployment of applications inside software containers. It has become prevalent in recent years due to its ability to streamline the process of shipping and deploying applications. Docker containers can be created on a developer’s workstation and then pushed to a testing, staging environment, or even production. What […]

Docker vs. Virtual Machines (VMs)

Docker is a container manager, while VMs are virtual machines. Using Docker means you aren’t limited to a physical machine, and you get to keep your host technology intact. In addition, VMs can be used even if you don’t have administrative access to the computer, which Docker VMs can’t do. Security is a major concern […]
