What Is DevOps?

learn what is DevOps in this DevOps tutorial

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to enhance collaboration, communication, and efficiency within an organization. Basically, it aims to bridge the gap between development teams (which are responsible for creating and updating software) and operation teams (which are responsible for maintaining and deploying software in production environments).

Key principles and practices of DevOps include:

  • Continuous Integration (CI).
  • Infrastructure as Code (IaC).
  • Monitoring and Logging.
  • Continuous Delivery.
  • Collaboration and Communication.
  • Continuous Delivery.
  • DevSecOps.
  • Agile and Lean Practices.

Why DevOps?

Earlier, there were two models being used- the Waterfall Model and the Agile method, before DevOps came into action.Let’s have a look to understand these Methods deeply.

1. Waterfall Method-

Waterfall Method

We know how the problems are faced in the traditional Waterfall model, which, as the name suggests, follows a sequential and linear approach. It has various phases and the output of one phase works as the input of the next phase. And if any mistake occurs in the flow of work, it cannot be diverted toward the previous state thus the whole process has to repeat itself. Interaction with the customer is zero.

The phases are- 

  • Requirement
  • Design
  • ImplementationVerification
  • Maintenance

The drawbacks of this method are-

  • The previous stage cannot be changed.
  • Not recommended for large-sized projects.
  • High risk of customer dissatisfaction.
  • Lack of early feedback.
  • Limited collaboration and communication.

2. Agile Model-

Agile Model

To resolve the waterfall model issues, a new method was used known as the Agile method. Under this, the whole development plan gets split into multiple iterations. It includes the interaction with the customers, but still, the issues evolved in the Agile model too. The problem is when the development team alters the code for better productivity and sends it to the Operations team,  there are chances of delay in the feedback from the operations team.

Each iteration includes the following stages-

  • Requirement
  • Design
  • Development
  • Release

The drawbacks of this method are-

  • Lack of Upfront Design.
  • Resource constraints.
  • Lack of predictability.
  • Continuous planning and re-prioritization.

Henceforth, to eliminate this delay, DevOps works as the solution. It allows the Development team and the Operations team to work together and interact directly. This thing further avoids delays, fixes bugs, and delivers quality data on time. DevOps allows continuous connection between both teams, from the deployment of the code to the testing of it. DevOps provides uninterrupted monitoring and immediate feedback, which in turn gives the best results. Look at the image below for a better understanding.

DevOps Tools: 

DevOps tutorial explaining DevOps Tools

In order to support various aspects of the DevOps lifecycle, various tools are used. Learn about some commonly used DevOps tools in this DevOps tutorial:

1. Version Control Tool-

  • Git: A distributed version control system for tracking changes in code repositories.

2. Continuous Integration (CI)/ Continuous Deployment (CD) Tools-

  • Jenkins: It is used for building, testing, and deploying software.
  • CircleCI: A cloud-based CI/CD platform for automating the software development process.
  • Travis CI: A hosted CI service that integrates with GitHub repositories.
  • GitLab CI/CD: It is an integrated CI/CD tool that is part of the GitLab platform.

3. Containerization Tools-

  • Docker: A platform that allows you to package applications and their dependencies into containers for easy deployment and scalability.
  • Kubernetes: It automates scaling, deployment, and management of containerized applications.

4. Configuration Management Tools-

  • Puppet:Used for automating the management of infrastructure and applications.
  • Ansible: Tool for configuration management, deployment, and orchestration.
  • Chef: For defining and managing infrastructure as code.

5. Infrastructure as Code (IaC) Tools-

  • Terraform: It allows you to manage and define infrastructure resources.
  • AWS CloudFormation: A service provided by AWS (Amazon Web Series) for providing and managing AWS resources using templates.

6. Monitoring and Logging Tools-

  • Prometheus: Used for collecting and analyzing metrics.
  • Grafana: A data visualization and monitoring tool that works with various data sources, including Prometheus.
  • ELK Stack (Elasticsearch, Logstash, Kibana): It is a combination of tools for log management and analysis.

These are the DevOps tools covered in this DevOps tutorial for beginners.

DevOps Architecture:

Have a look at the DevOps phases in this DevOps tutorial.

DevOps architecture

1. Plan

The requirements like cost and time are discussed in this phase, which gives a brief idea to everyone about the project.

2. Code

Here, the code is written as per the client’s requirements. And further, the code gets split into small codes called units to receive a clear code picture.

3. Build

The unit building is done while going through this stage.

4. Test

The units get tested in this stage for hassle-free results.

5. Integrate

Jenkins tool is used in this for code integration. It creates to one connection between development and operation teams.

6. Deploy

The code gets deployed while going through this phase. The tools used for deployment are AWS and Docker.

7. Operate

Operations are executed on the code in this stage. Tools used are Kubernetes and Open Shift.

8. Monitor

The Application monitoring gets processed in this phase. Tools used are Nagios and Elastic Stack.

Applications of DevOps:

Let’s learn about some of the applications of DevOps in this  DevOps tutorial: 

1. HP- 

When testing the software this company faced problems. There used to be manual testing to detect the bugs and if any bugs were found, then it used to take around one week to fix the issues. Henceforth, to resolve this problem, they started using CI and CD pipelines.

2. United Airlines

This company started using DevOps for testing and changed its previous method of testing.

3. Amazon and Netflix

To control a large amount of traffic, this company started adopting DevOps.

4. Adobe

The issues faced by this company were about the monolithic architecture. For that, they switched to CI/CD pipelines for end-to-end communication.
