Introduction to Heptio Ark

An Ark is a vessel or sanctuary that is supposed to serve as protection against extinction. The most famous Ark in history is Noah’s Ark, which the Bible says was built with instructions from God to protect Noah’s family and the pairs of animals he was instructed to bring on board. A more modern Ark would be the Svalbard Global Seed Vault which stores seeds in case of a global crisis.

Blue/Green Deployment with AWS Part - II

In my last blog, I talked about the blue/green deployment and the use of AWS services in blue/green deployment. In this blog, I will mainly talk about blue/green deployment using the DNS redirection with Route 53.

What’s new in Kubernetes 1.7?

Kubernetes is one of the popular platforms for container orchestration and management. After focusing more on the stability front in 1.6, Kubernetes 1.7 has more than fifty new features and more focus on federation, extensibility, security, and other ways of deploying, scaling, and managing containerized applications. Here are some new features that make Kubernetes 1.7 more stable and popular.

DevSecOps- Next Stride for DevOps

The global IT market is expanding at warp speed, and IT spending is now touching a figure of $4 Trillion. In the current scenario, data is the biggest commodity. Data is more valuable and powerful than ever. And like Uncle Ben Parker said, “With great power comes great responsibility.” Security has always been a big concern for valuable things, and IT is no exception. IT is trying to bring the security factor more leftwards in a development cycle. Rather, they are trying to involve it in every step of the development cycle.

Continuous Testing in DevOps

Software has shifted from a role of supporting the business to being a major source of innovation, resulting in increased demands for faster development. Agile development results from this demand, increasing the speed of development and delivery. However, this increased pace of development has meant more pressure on Ops and QA teams to release more software reliably. Test teams face a trifecta of pressures based around:

How to deploy Docker images on OpenShift?

OpenShift is a container application platform that sits on top of Kubernetes and is a superset. Anything that works in Kubernetes will also run in OpenShift with the advantage that it lets you easily and quickly build, develop, and deploy any of your infrastructures. It is a PaaS that abstracts the underlying components by providing an interface that runs on top of IaaS.

DevOps Assessment - Assess, Analyse, Implement, Achieve!

My last blog discussed DevOps and How you can get more out of your DevOps with containers. It discussed various possibilities of combining your DevOps practices with containers on-premise and in the cloud and a combination of both.

How does Blue/Green deployment work with AWS?

In one of our projects, we were working on the production upgrade of a large web application. The process involved upgrading multiple services and their components on different web application servers. With the traditional approach, the application had to be stopped for a certain maintenance window and redeployed with the latest code, services, and components. The main hurdle was to debug the application after upgrades and enable rollback to the previous stable version in case of failure.
