In today's world, the need for highly available and fault-tolerant systems is more important than ever. Furthermore, with the increased adoption of microservices and containerization , the need for a reliable infrastructure that can automatically detect and recover from failures has become critical. Kubernetes , an open-source container orchestration platform, and Prometheus, a popular monitoring and alerting toolkit, are two tools that can be used to implement such a self-healing infrastructure

Kubernetes has become the de facto standard for container orchestration, enabling organizations to build, deploy, and scale modern applications with efficiency and agility. As more organizations adopt Kubernetes, the need for proper security and management of sensitive data within these environments becomes paramount. One crucial aspect of ensuring a secure Kubernetes infrastructure is the effective management of secrets, such as API keys, passwords, and tokens.

Log forensics—investigating security incidents based on log data—has become more challenging as organizations adopt cloud-native technologies. Organizations are increasingly turning to these cloud environments to stay competitive, remain agile, and grow. But as organizations rely more on cloud environments, data and complexity have proliferated. Teams struggle to maintain control of and gain visibility into all the applications, microservices and data dependencies these environments generate.

In today's fast-paced software development landscape, microservices have emerged as a popular architectural pattern. But what exactly are microservices? In a nutshell, microservices are a way of structuring an application as a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This architectural style enables teams to develop and deploy services independently, offering flexibility and scalability to the software development process.

As a database administrator, have you ever been in a situation when your database confronted a brute force attack? A brute force attack can be launched against a user account in MySQL. MySQL replies with success or error based on supplied credentials, and the time required for the verification is almost the same in either case. Hence, an attacker can launch a brute force attack against a MySQL user account at a rapid rate and can try many different passwords.
