Reading Time: 3 minutes Hi everyone! I’m back with a new blog where will be discussing a term called DevSecOps. This term directly related to a very important component of technology which is security. So let’s discuss what is DevSecOps? Why it’s so much important? How it comes into the picture?
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: 7 minutes Hi all, In one of my previous blogs, I discussed Apigee, what it is and why is it required? We also discussed the various features and benefits of having Apigee. We saw how to deploy a proxy through the code rather than the Apigee UI deployment feature and many more. So if you like you can go through the basics of Apigee here Getting started Continue Reading
Reading Time: 2 minutes In our earlier blog Introduction to Mesos , we have talked about basic idea of Mesos. And How it works and its basic terminology. Till now we have discussed the theoretical concepts to get ourselves familiar with Mesos and now we will be going to install the mesos and see how we can monitor mesos using UI, So let’s get onto it. Step1: Download Mesos Continue Reading
Reading Time: 4 minutes What is Mesos ? In layman’s term, Imagine a busy airport. Airplanes are constantly taking off and landing. There are multiple runways, and an airport dispatcher is assigning time-slots to airplanes to land or takeoff. So Mesos is the airport dispatcher, runways are compute nodes, airplanes are compute tasks, and frameworks like Hadoop, Spark and Google Kubernetes are airlines companies. In technical terms, Apache Mesos Continue Reading
Reading Time: 2 minutes In our previous blog we have seen how to deploy the lagom service on conductr – https://blog.knoldus.com/2017/05/25/deploying-the-lagom-service-on-conductr/ In this blog we will create script to deploy your Lagom service on conduct present or running on top of DCOS. There are two types of automatic deployments can be done – Deploying from scratch (stop the current Lagom bundle and deploy the new one) Rolling/Incremental Deployment( Overriding Continue Reading
Reading Time: 2 minutes In one of our previous blog, Setup a Apache Spark Cluster in your Single Standalone Machine, we showed how to setup a standalone cluster for running spark applications. But we never discussed on how to deploy our Spark applications on that cluster. So, in this blog, we will see how to deploy our Spark application on a cluster and use it to run our spark jobs. For Continue Reading
