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 […]
Introduction In this blog, I have checked application availability when one of the availability zones is down. AWS has regional services where there are more than one data centers, which are known as availability zones, to ensure High availability and redundancy. For instance, we have three availability zones for the ap-south-1(Mumbai) region, i.e., ap-south-1a, ap-south-1b, […]
Nowadays, every org wants to migrate to a microservices architecture; the idea sounds great on paper. But when you’re staring at an 8-year or decade-old monolith that processes millions of transactions and somehow never breaks, suggesting a complete rewrite feels… well, insane. I’ve been down this road more times than I care to admit. Be […]
Introduction For over a decade, we’ve relied on AWS Managed Kubernetes (EKS) clusters to deploy our microservices workloads. As businesses increasingly depend on cloud-native applications, security, and compliance have become critical components for ensuring business continuity and growth. These applications, deployed across clusters, need to interact securely with other cloud services, adhering to the principle […]
Introduction In today’s fast-paced DevOps world, technologies like Kubernetes, OpenShift, and CI/CD are reshaping how applications are deployed and managed. Many enterprises are transitioning to Red Hat OpenShift for faster and more secure application deployments. This article explores the evolution of cloud deployment technologies—from bare metal to virtualization, containers, and finally, Kubernetes & OpenShift—along with […]
