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.

Historically MySQL is great in horizontal READ scale. The scaling, in that case, is offered by the different number of Replica nodes, no matter if using standard asynchronous replication or synchronous replication. However, those solutions do not offer the same level of scaling for writes operation. Why? Because the solutions still rely on writing in one single node that works as Primary.

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.

Time series analysis is a specialized branch of statistics that involves the study of ordered, often temporal data. Its applications span a multitude of fields, including finance, economics, ecology, neuroscience, and physics. Given the temporal dependency of the data, traditional validation techniques such as K-fold cross-validation cannot be applied, thereby necessitating unique methodologies for model training and validation.

In simpler terms, logical replication in PostgreSQL is a way to copy data from one database to another in a more flexible and customizable manner compared to physical replication. Instead of copying the entire database, logical replication focuses on replicating changes made to individual rows or transactions. To set up logical replication, you create a publication on the source database and a subscription on the target database.

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.

When code breaks, our first move is carefully inspecting the call stack. It helps us find the needle in the haystack by understanding how, where, and why the failure occurred, including how we got there. However, in a message-based system, we no longer have a single call stack. We’ve exchanged it for a haystack of call stacks , which makes finding the needle (the root cause of the failure) even more difficult. ?
