An Introduction to Kubernetes Architecture! 

Kubernetes is an open-source container orchestration platform used for running distributed applications and services at scale. Merely knowing the basics of Kubernetes won’t be sufficient enough in order to leverage the many advantages that it offers. It’s important to first understand the complete Kubernetes architecture, its components and how they interact with each other to know how Kubernetes actually works. Let’s take a brief look and explore how the different components of Kubernetes work together.

Kubernetes is the ideal solution for complete orchestration, scaling and deployment of containerized applications. You can also read about application containerization, Kubernetes API, Kubernetes API Gateway and much more here!

Nginx monitoring using Telegraf/Prometheus/Grafana

Nginx is one of the most popular and widely used web servers mostly because of its speed and reliability. Nevertheless, it is paramount to keep track of the performance and availability that would help you to proactively prepare yourself for the worst scenarios like sudden/unexpected hikes in traffic. It will also keep you updated about the current state and health of your application.

This article will guide you on how to get Nginx Web Server metrics and visualize them. The main goal is a quick deployment and configuration using well-known open-source projects like Grafana, Prometheus, and Telegraf.

Prometheus: An open-source, time-series database for event monitoring and alerting managed by the Cloud Native Computing Foundation (CNCF).

Grafana: An Open-source project for analytics software and visualization of the metrics from any database.

Telegraf: An Open-source project, plugin-driven agent to collect and send metrics.

Your Guide for Patching Elastic Search!

What is Patching?

A patch is a set of updates to a server or its supporting data designed to update, fix and improve, including fixing security vulnerabilities and other bugs. They may be applied to program files on a storage device or in computer memory. Patches may be permanent or temporary. 
In a brief overview, you need to perform the following tasks for patch management: 
 1. Create a patch catalog.
 2. Analyze the target to determine the patches that need to deploy.
 3. Deploy the required patches to targets requiring remediation.
 4. Analyze the targets again to ensure each server has the correct patch.
