Docker Engine is a containerization platform that allows you to run applications in isolated environments, called containers, on a host operating system. It provides a lightweight and portable way to deploy applications, ensuring consistency and reliability across different environments. In short, docker engine is the host with docker installed on it.
Docker Engine consists of several components:
Docker Daemon:
Description: The core service for running containers. Function: It listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes.
Docker Swarm Docker Swarm is a native Docker orchestration tool that allows you to deploy and manage multiple Docker containers as a single unit. In this article, we’ll cover the basic setup of Docker Swarm, including creating a swarm, adding nodes, and deploying a service.
Prerequisites
Docker installed on multiple machines (nodes) Docker version 1.12 or later All nodes must be able to communicate with each other Step 1: Create a Swarm
Docker Container Orchestration Docker container orchestration refers to the process of automating and managing the deployment, scaling, and management of multiple Docker containers. Container orchestration tools provide a way to define, deploy, and manage complex applications composed of multiple containers, ensuring that they work together seamlessly and efficiently.
Some of the key benefits of container orchestration include:
Scalability: Orchestration tools allow you to scale your application horizontally by adding or removing containers as needed, ensuring that your application can handle changes in traffic or demand.
Running Docker on Windows: A Comprehensive Guide
Docker, a popular containerization platform, has revolutionized the way developers and organizations deploy and manage applications. Initially designed for Linux, Docker has expanded its support to Windows, making it possible to run Docker containers on Windows operating systems. In this article, we’ll delve into the world of Docker on Windows, exploring the different types, options, and features available.

The OWASP Security Principles are a set of guidelines for designing and implementing secure software systems. OWASP (Open Web Application Security Project) is a non-profit organization that aims to improve the security of web applications.
Here are the OWASP Security Principles:
Security by Design: Security should be considered throughout the entire software development lifecycle, from design to deployment. This principle emphasizes the importance of integrating security into every stage of the development process.

Language Processors: Types and Examples
In the world of computing, language processors are essential tools that help developers write, compile, interpret, and execute code written in various programming languages. Language processors encompass a range of software components such as compilers, interpreters, assemblers, and linkers, each serving a specific purpose in the software development lifecycle. This article explores the types of language processors, their functionalities, and provides examples of popular processors used in the industry.
Error:
When you try to login to a server through rdp, you ll end up in “No Remote Desktop License Servers Available” error or you cannot login as no remote desktop license server is available error.
Root Cause:
If you have installed rds role on a windows server OS, by default only 3 logins are allowed. One console session and two rdp sessions. This works for 120 days. After this time is completed, you cannot login to the server.
