EKS Cluster AutoScaler

The Amazon EKS AutoScaler automatically adjusts the number of worker nodes in an Amazon EKS cluster based on resource utilization and scaling demands.

Before we started using EKS Cluster Autoscaler, managing node scaling in our Kubernetes cluster was a constant struggle. Here’s what we were dealing with:

High Costs: We had to keep extra EC2 nodes running all the time to avoid pod scheduling issues — even when they weren’t being used.

Pod Failures: If we tried to reduce node count to save money, pods would often stay Pending due to lack of resources.

Manual Work: Scaling nodes up or down was a manual task—time–consuming and error–prone.

Slow Deployments: During deployments or traffic spikes, our workloads would get stuck because there weren’t enough resources.

Unpredictable Demand: Our workloads change frequently, but our cluster capacity doesn’t— leading to overuse or underuse of nodes.

These challenges pushed us to explore Cluster Autoscaler, and it turned out to be a game–changer

Load Testing using AWS Distributed System – Part 1

In today’s fast-paced world, ensuring your application and business can handle growing users is very important. Whether you are building a Mobile application, Web application, or REST API it is important to understand how our system performs under pressure. Load testing is one of the ways we identify the bottlenecks, performance issues, and potential feature failures before the end user identifies it.

While consulting for an Edtech platform they highlighted an issue of having a dynamic and distributed load testing environment that can scale itself if we want to generate more load to the system and once the goal is achieved it should incur minimal cost to the organization since we are not leveraging a static provisioned environment.

AWS Distributed load testing system is a powerful automated setup provided by AWS that can be installed in our AWS cloud environment. This setup helps developers and testers generate real-world traffic at scale and test how well the system handles it. In this blog, we will talk about how the AWS Distributed Load Testing system works and how it can be leveraged to improve the reliability and performance of the system.

Cybersecurity Roadmap: Part 1 – A Step-by-Step Guide

Introduction to Cybersecurity

In today’s tech-driven landscape, cybersecurity has become essential rather than optional. As businesses and individuals increasingly depend on technology for storing, processing, and sharing information, the dangers posed by cyber threats have surged dramatically. Cybersecurity is all about protecting systems, networks, and data from unauthorized access, destruction, or theft.

With the rise of ransomware attacks, phishing scams, and data breaches, cybercriminals are continually adapting their methods. This reality underscores the importance for organizations of every size to take a proactive and strategic stance in safeguarding their digital resources. By cultivating a robust cybersecurity strategy, companies not only protect sensitive information but also foster customer trust and ensure smooth business operations.
