DevOps Training
Institute in Hyderabad

DevOps is a software development approach involving Continuous Development, Continuous Testing, Continuous Integration, Deployment and Monitoring.

The above process spans across the traditionally siloed teams of Development and Operations and DevOps tries to remove the barriers between them.

So, a DevOps Engineer works basically with the DEVelopment and OPerations team. It's the link between those 2 main parts.

Topics Covered

DevOps won't have much value without the cloud, and the cloud won't have much value without DevOps.

The centralized nature of Cloud Computing provides DevOps automation with a standard and centralized platform for developing, testing and deployment.

As a DevOps engineer, you would be working with infrastructure on cloud environments. So, in this section we are going to work on creating servers in the AWS environment along with some other basics in AWS Cloud.

Topics Covered

You also need to know the basics of Networking & Security in order to configure the infrastructure. However, to draw a line here between DevOps and IT Operations: You are not the SysAdmin. So you don't need advanced knowledge here.

Topics Covered

Linux is everywhere. Today, Linux runs many of the technologies that power up devices and services. From mobile phones, Google applications, social media networks, to GPS services, Internet of Things (IoT) and Artificial Intelligence (AI) products etc.

Since DevOps teams share many responsibilities, A DevOps engineer who knows how to configure operating systems and networking technologies will potentially have few software delivery obstacles.

Knowing how to configure Linux for DevOps is essential to a continual and speedy software delivery process

Topics Covered

As a DevOps Engineer, you'll work collaboratively with development and operation teams to deploy and operate our systems.

So, in this section, we are going to understand how the application architectures work and we set up practically those applications in AWS EC2 Environments Manually. Also, will further proceed to set up our applications in an automated way using Ansible and streamline our operations and processes.

Topics Covered

Continuous Integration and Continuous Delivery (CI/CD) are often cited as pillars of successful DevOps Implementation. To establish and optimize the CI/CD model and reap the benefits, companies need to build an effective pipeline to automate their build, integration and testing processes. At a high level, the pipeline “includes compiling, packaging, and running tests.

For the next sections, we are going to cover the tools which help in making the pipelines to deliver the code to production in a smooth manner. We will use GIT/GITHUB, Will talk about build tools like Maven, Will talk about testing tools using CodeQuality testing using SonarQube, Will talk about Nexus Manager.

Git is a Version Control System for tracking changes in computer files and coordinating work on those files among multiple developers. It is primarily used for source code management in software development.

Topics Covered - Git / GitHub

The process of building software is usually managed by a build tool in our case it's MAVEN

Maven’s primary goal is to allow a Developer to comprehend the complete state of a development effort in the shortest period of time.

Topics Covered - Maven

SonarQube is an open source platform developed by SonarSource for continuous inspection of Code Quality.

SonarQube offers reports on duplicated code, coding standards, unit tests, bugs and security vulnerabilities

SonarQube provides fully automated analysis and integration with Maven and Continuous Integration tools like Jenkins

Topics Covered - SonarQube

Nexus manages software "artifacts" required for development. If you develop software, your builds can download dependencies from Nexus and can publish artifacts to Nexus creating a new way to share artifacts within an organization

Topics Covered - Nexus

Jenkins is an open source automation server written in Java. Jenkins helps to automate the non-human part of the software development process, with Continuous Integration and Continuous Delivery.

Topics Covered - Jenkins

Configuration management is important in DevOps because it helps you automate tedious tasks or take away complexity.

Without automation, building and maintaining large-scale modern IT systems can be resource-intensive and can lead to increased risk due to manual error.

Configuration management is important because it gives you consistency of systems and software enables the ability to scale infrastructure and software systems without having to correspondingly scale administrative staff to manage those systems.

Topics Covered - Ansible

Terraform is a tool that helps you manage various cloud infrastructure services in the form of code. You codify your infrastructure, and so it's also known as Infrastructure as Code (IaC).

Topics Covered - Terraform

The Docker tool was designed for developers and system administrators, an essential part of DevOps. With Docker, developers can focus on application development rather than being worried about the platform where it will run.

Docker can run many applications by using the same hardware. Developers can create ready to run container applications through Docker. It has made deploying and managing applications quite easier.

Every enterprise that is using DevOps can use Docker so that it can deliver an efficient and quick application to its customers. Any size of the Company can deliver such amazing applications by using the DevOps Docker tool.

Topics Covered - Docker

Nowadays it’s critical to get your releases out fast, which requires having an automated CI/CD pipeline that takes your code from text to binaries to a deployed environment.

Implementing an automated pipeline in the past has been challenging, especially when dealing with legacy applications. This is where Dockers and Kubernetes come in.

Kubernetes has revolutionized the way we deploy and manage our containerized applications.

Using Kubernetes, you gain simplified application deployment. Kubernetes is one of modern DevOps tools which reduces the deployments from days to minutes.

We are going to discuss containerization technologies and the basics of Docker. Then we are going to talk on kubernetes, where we will implement the Kubernetes Production Cluster and deploy the applications on the Production Cluster.

Topics Covered - Kubernetes
