Introduction Running Kubernetes workloads on Amazon EKS is easy, but running them in a cost-effective way is a different challenge. Many organizations start their Amazon EKS clusters with Managed Node Groups based on Auto Scaling Groups (ASGs). This is a reliable approach but often results in over-provisioning of infrastructure as worker nodes are kept running […]
Introduction Someone deletes a namespace by accident. A migration goes sideways and you need last week’s cluster state back, not just today’s. A node group gets torn down before anyone thought to check what was running on it. Kubernetes does not protect you from any of this by default etcd holds your cluster’s state, but […]
A Practical Guide to Fixing CVEs in Amazon EKS Worker Nodes by Updating Node Group AMIs Learn how to identify security vulnerabilities (CVEs) in your EKS worker nodes, update them safely without affecting running applications, and automate the process so your clusters stay secure over time. Executive Summary When you create an Amazon EKS cluster, […]
Modern applications require scalability, flexibility, and faster deployments. Traditional monolithic architectures often struggle to handle these demands. This is where microservices architecture becomes highly valuable. Microservices break an application into small, independent services that communicate through APIs. When combined with Docker containerization, microservices become easier to deploy, scale, and maintain. In this article, we will […]
Introduction What if upgrading your Kubernetes cluster required no downtime at all? Imagine if you could upgrade your Kubernetes cluster and keep everything running smoothly, with zero downtime. Sounds pretty great, right? A lot of teams worry that upgrading will mean their apps go offline, but with solid planning, it’s actually possible to have safe […]
Introduction As the Kubernetes cluster grows it becomes very difficult and complex to manage the communications between different microservices as the N numbers of services interacts in real time and identifying issues like failed connections, packet loss, unstable connections becomes challenging. Istio Service Mesh provide solutions to these challenges by creating infrastructure layer that handles […]
The Problem With ‘Flip the Switch’ We’ve all been there: the new version is ready, the tests are passing in the staging environment, everybody is reasonably confident, and you deploy – only to find out that in a matter of minutes, the error rates are through the roof. Suddenly, you’re in the process of an […]
Introduction Nowadays, Managing the Microservices that are interacting with each others in real time becomes challenging especially when the clusters are running with hundreds of these microservices. There’s always somethings breaking up or causing performance issues and for looking into these issues you need to go thoroughly with the traffic flow, need to understand where […]
Introduction In today’s rapidly evolving technological landscape, database management has become more complex yet essential for ensuring high availability, scalability, and resilience. One of the most effective ways to manage MySQL databases in a cloud-native environment is by integrating InnoDB Cluster with Kubernetes and containers. This integration leverages MySQL Group Replication and MySQL Router to […]
