OpenShift is a cloud development Platform as a Service (PaaS) developed by Red Hat. It is an open-source development platform, which enables developers to develop and deploy their applications on cloud infrastructure. It is very helpful in developing cloud-enabled services. This tutorial will help you understand OpenShift and how it can be used in the existing infrastructure. All the examples and code snippets used in this tutorial are tested and working code, which can be simply used in any OpenShift setup by changing the current defined names and variables.

🔹 In this blog, we will be demonstrating the working of network topology. 🔹

🔰 Create a network Topology Setup in such a way so that System A can ping to two Systems System B and System C but both these systems should not be pinging each other without using any security rule e.g firewall etc.

At first all the systems can ping each other. Let’s verify that.

👉🏻 SystemA : Here, SystemA can ping to SystemB and SystemC

What Is Ansible?

Ansible is an open source IT Configuration Management, Deployment & Orchestration tool. It aims to provide large productivity gains to a wide variety of automation challenges. This tool is very simple to use yet powerful enough to automate complex multi-tier IT application environments.


Ansible is a software tool that provides simple but powerful automation for cross-platform computer support. It is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. It is primarily intended for IT professionals, who use it for application deployment, updates on workstations and servers, cloud provisioning, configuration management, intra-service orchestration, and nearly anything a systems administrator does on a weekly or daily basis. Ansible doesn’t depend on agent software and has no additional security infrastructure, so it’s easy to deploy.

Because Ansible is all about automation, it requires…

What is AWS ?

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, offering over 175 fully featured services from data centers globally. Millions of customers — including the fastest-growing startups, largest enterprises, and leading government agencies — are using AWS to lower costs, become more agile, and innovate faster.

What is AWS CLI ?

The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services. With just one tool to download and configure, you can control multiple AWS services from the command line and automate them through scripts.

What is Machine Learning(ML)?

Machine Learning is the field of study that gives computers the capability to learn without being explicitly programmed. ML is one of the most exciting technologies that one would have ever come across. As it is evident from the name, it gives the computer that makes it more similar to humans: The ability to learn. Machine learning is actively being used today, perhaps in many more places than one would expect.

Let’s understand few concepts related to it🧐

What is Jenkins

Jenkins can be termed as an open source continuous integration server that helps developers by orchestrating a chain of actions, to achieve the Continuous Integration process in a automated way.

Jenkins supports the complete development lifecycle of software from building, testing, documenting the software, deploying and other stages of a software development lifecycle. Jenkins is free and is entirely written in Java. Jenkins is a widely used application around the world that has around 300k installations and growing day by day.

Company BlackRock


The world’s largest asset manager, BlackRock operates a very controlled static deployment scheme, which has allowed for scalability over the years. But in their data science division, there was a need for more dynamic access to resources. “We want to be able to give every investor access to data science, meaning Python notebooks, or even something much more advanced, like a MapReduce engine based on Spark,” says Michael Francis, a Managing Director in BlackRock’s Product Group, which runs the company’s investment management platform. “Managing complex Python installations on users’ desktops is really hard because everyone ends up with slightly different…

What is Docker ?

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.

The Docker platform

Docker provides the ability to package and run an application in a…
