The expectations in the paper were roughly rounded up to the following points: Sharing of Data & Resources. Programming Abstractions. Debugging & Monitoring. Mesosphere DC/OS, as a datacenter os, does the following above things for the user. The actual feeling you get when you use DC/OS is similar to Continue Reading
Reading Time: 2 minutes In this blog, we are going to deploy a sample load balanced app over DCOS and expose it to the outside of the cluster using Marathon-lb. Here we will be using a containerized application which serves a DCOS site. Here we are using Marathon-lb as an external load balancer. It is based on HAProxy which provides proxying and load balancing for TCP and HTTP based applications. Continue Reading
Reading Time: 3 minutes Once upon a time, the software was built using the Waterfall model. This model was simple and easy to understand and use. It is easy to manage due to the rigidity of the model – each phase has specific deliverables and a review process. But, it was painstakingly slow; the builds took a long time to build and deploy. But in this world of heavy Continue Reading
Reading Time: 4 minutes First, There was Waterfall model, software builds took a long time to develop and then deployment alone was time-consuming. Now, Agile, revolutionizing the way we follow the development cycle making it faster, deliverables have the same quality and they are delivered much faster. Bang! and Now we have Dev Ops.. Where the Agile methodology releases build annually, quarterly or monthly, Dev Ops speed up the Continue Reading

All the infrastructure is provided by companies like AWS, Google, Azure Continue Reading
Reading Time: 5 minutes Jenkins came with a big bang. That said, it enhanced the whole process of continuous integration & continuous deployment. The challenge that a dev faces is to deliver the most updated and safe code to the customer. The advent of CD(continuous deployment) pipeline automates expression of the process to get the software from the version control system directly to the user. This expression, which does Continue Reading
Reading Time: 4 minutes Jenkins is a cross-platform, continuous integration and continuous delivery application that can be used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build, which in turn increases your productivity. When you are working on a number of projects which get built on a regular Continue Reading
