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!

AWS SECRET MANAGER

Introduction

Most of the IT companies are working or are migrating their infrastructure to the cloud environment for cost reduction, high availability, data security, and hassle-free setup. Companies create or use applications/databases on the cloud, where they need to authenticate via secrets (or credentials). These days protection of passwords is one of the challenges, and hard-coding the secrets into the system would be a major security issue. Hence, we can make use of the AWS service named Secret Manager that will be responsible for the management of secrets.

What is a Secret?

A secret is not just a pair of usernames and passwords. It might contain a set of credentials holding key-value pairs or connection details to access the related services. In AWS Secret manager, a secret has metadata:

An Amazon Resource Name, name of the secret, a description, a resource policy, and tags, ARN for an encryption key (an AWS KMS key that Secrets Manager uses to encrypt and decrypt the secret value), Information of rotation of secret.

Complete Guide to Nginx Monitoring with Telegraf, Prometheus, and Grafana

To effectively monitor Nginx using Telegraf, Prometheus, and Grafana, first enable the Nginx status page. Next, set up Telegraf to collect these metrics and output them in a Prometheus-friendly format. Then, configure Prometheus to scrape data from Telegraf. Finally, use Grafana to view the collected metrics.

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.

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.

AWS LAMBDA – Here’s Everything You Need to Know!

What is Serverless?

To understand what AWS Lambda is, we have to first understand all about serverless architecture. The serverless architecture is a way to build and run applications and services without having to manage infrastructure. Your application still runs on servers. When you run a serverless application, you get the benefit of not worrying about OS setup, patching, or scaling of servers that you would have to consider when you run your application on a physical server.

Serverless applications or platforms have four characteristics:

No server management
Flexible scaling
No idle capacity
High availability
