Apache Cassandra Migration: 3.x to 4.x Ep: 2 DC and DR Setup

Well in my previous blog, we learned about Cassandra’s basics. If you have not read it yet, you should go through it. We have discussed the basics of Cassandra which will be useful in your daily operations on the database.

So now we will deep-dive into Cassandra’s DC/DR Setup.

DC/DR setup is necessary in a production environment where you don’t know when an issue can occur. You need to have an immediate backup when your cluster is down, and you should always have another cluster to respond.

Cassandra is a database and for a database, we want it to remain up in any and every situation to avoid downtime of our applications. Disaster Recovery setup of databases is equally necessary as you do for your applications. So let’s get started with this super easy way where it will take a few minutes and make your DR Setup ready.

How to get Java heap dump from Kubernetes container into a local machine?

Overview

Java is famous for its robust garbage collector algorithm, yet it is still possible to have memory leaks in JVM applications. To deal with this, it is important to obtain and analyze a heap dump to identify potential leaks in our application.

In this short tutorial, we will explore how to generate a Java heap dump from an application running as a Kubernetes pod.

We will first check the authenticity of the heap dump. Next, we will create a simple test application that we will later deploy as a pod on Kubernetes. Finally, we will demonstrate the process of getting a heap dump from our application.

Introduction to External Secret Operator

ESO

In today’s digital world, the protection of sensitive information has become paramount. So while working with microservices orchestrator tools such as kubernetes it is important to handle the secrets securely such as username or password, DB Password, or API Keys. Kubernetes has a built-in feature for managing secrets called secrets. But the downside of Secrets is that It doesn’t support storing or retrieving the secrets from external secret management systems like AWS Secrets Manager, HashiCorp Vault, Google Secrets Manager, Azure Key Vault, IBM Cloud Secrets Manager, and many more.

Moreover, external secret management provides encryption at rest, secret rotation policies, and many more. So in this blog, we will talk about the solution GoDaddy came up with an open-source solution called External Secrets Operator.

What is External Secret Operator?

External Secrets Operator is a tool or component that extends the functionality of Kubernetes to manage external secrets in a more secure and efficient manner. It acts as a bridge between Kubernetes and external secret management systems, allowing you to securely store and retrieve secrets from external sources. It integrates with external secret providers such as HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, or other similar systems. This enables Kubernetes applications to access and utilize secrets stored in these external systems without exposing them directly within the cluster.
