What is DevOps?

DevOps is a dynamic approach that enhances the efficiency of software development by automating the operational aspects of the process.

It fosters improved collaboration between developers and the operations team through the utilization of diverse automation tools. The DevOps lifecycle involves the integration of various automation tools at different stages, as depicted in the accompanying image.

What is Automation?

Automation is a technological method aimed at executing tasks with minimal human intervention.

Some key motives behind embracing automation include:

1. To minimize human errors.

2. To alleviate the burden of daily repetitive tasks.

3. To enable IT teams to concentrate on more strategic and high-value projects.

4. To expedite the development of tested and validated applications with zero downtime.

What is Scaling?

Imagine you have a website with 100 users presently, and you anticipate a surge to a million users in the next six months. What steps would you take?

The answer lies in scaling – adjusting the underlying infrastructure of your software system to accommodate the increased load or usage. There are two approaches to scaling in software:

1. Vertical Scaling: Enhancing the capacity of a single server by increasing RAM, CPU capability, or storage capacity.

2. Horizontal Scaling: Adding more machines to a cluster of software servers to fortify your software system.

What is Infrastructure?

Consider driving a car to your favorite destination, where you control acceleration, gear changes, and braking at your will. There is intricate machinery supporting you, such as the engine, battery, or fuel tank.

Similarly, your software application relies on the underlying hardware, storage, networking, etc., collectively referred to as Software Infrastructure.

Why DevOps is significant?

Before the advent of DevOps, the interaction between development and operations involved numerous back-and-forth actions, causing delays in product releases. Enter DevOps.

DevOps accelerated product deliveries, bridging the communication gap between development and operations. The overall quality of software and products witnessed improvement.

Common Tools in DevOps:

1. Version control systems: Git, SVN

2. Configuration management tools: Ansible, Puppet

3. Continuous integration tools: Jenkins

4. Containerization technologies: Docker

5. Cloud platforms: AWS, Azure, GCP

6. Monitoring tools: Nagios, Splunk

7. Container Orchestration tools: Kubernetes
