What is DevOps?

DevOps is a “culture which promotes collaboration between Development and Operations Team to deploy code to production faster in an automated & repeatable way”.

Shortcomings of the traditional way

Development and operation teams used to work in complete isolation.
Teams used to spend a big amount of their time in deploying instead of development of the project.
Manual code deployment ~ human errors in production
Coding & operation teams have their separate timelines and are not in sync and cause the delay.

Result - Wall of Confusion

With all the shortcomings mentioned above, there is always a wall of confusion between dev and operation team which results in “Failure”.

Why is DevOps needed?

Allows teams to implement Continuous Integration and Continuous Delivery
Provides Predictability by offering a lower failure rate of releases
Provides resiliency by keeping the app more stable and secure
Helps the team to provide quality as it captures infrastructure issues.

How is DevOps different from Agile?

Typical IT Process

It gives us a picture of our typical IT process which consists of three teams – Requirement gathering team, development and testing team along with a separate operation team

Agile Implementation

It gives us a picture of our typical IT process with an agile implementation where there is a clear communication between the requirement gathering team and development and the testing team (where BA is sitting with the team rather than creating a SRS and leave forever) along with a separate operation team

Devops Implementation

It gives us a picture of our typical IT process with an agile implementation where there is a clear communication between a requirement gathering team and a development and operation team (where DevOps / Ops person is sitting with the team rather than sitting on another floor and taking a whole day to get development code to production) along with a separate requirement gathering team

DevOps Principles

End-To-End Responsibility
Continuous Delivery
Automate everything
Monitor everything

DevOps Categories

Infrastructure Automation
Configuration Management
Deployment Automation
Performance Management
Monitoring

Infrastructure Automation

“It’s a capability of providing more servers based on traffic automatically, no hardware cost up-front.”

Configuration Management

“It’s a process of scripting environments — from installing an operating system to installing servers on instances; i.e. environment configuration as a script.”

Deployment Automation

“It’s a process of providing continuous integration and testing along with finding issues as soon as a build is deployed”

Performance Management

“It’s a process of offering real-time performance monitoring which eventually helps developers to debug when issues occur."

Monitoring

“It’s a process of being notified when infrastructure and related services go down.”

One Solution – Azure Devops

It gives us an effortlessness of deploying an API into the cloud by using best practices like infrastructure as code using ARM
