In this article, we will answer some basic questions related to DevOps like

What is DevOps? Why DevOps? what tools do we use?

let's get started...

So, What is DevOps?

DevOps is a software development methodology that combines software development (Dev) and information technology operations (Ops). The main goal of DevOps is to shorten the systems development life cycle and provide continuous delivery with high software quality.

Let me make it clear clear for you :

You made one application and you want to send it to your customer. This sending process takes 10 days.

Now, we automate this thing and deliver this application in less than 10 days.

So, DevOps can be describe as a process of improving application delivery by ensuring

  • Automation: Reducing manual processes through automation.

  • Quality Assurance: Ensuring that the delivered product meets high-quality standards.

  • Monitoring: Constantly keeping an eye on systems and applications for issues.

  • Testing: Employing continuous testing to validate code and configurations.

What are the pillars of DevOps?

The key pillars of DevOps are:

  • Automation: Automating repetitive tasks through code and tools to improve speed, reliability, and reproducibility.

  • Continuous Integration: Merging code changes frequently to detect issues early.

  • Continuous Delivery: Releasing new updates frequently through automation.

  • Continuous Monitoring: Monitoring applications and infrastructure to detect issues quickly.

  • Infrastructure as Code: Managing and provisioning infrastructure using code.

  • Culture of Collaboration: Breaking down silos between teams through communication and sharing of knowledge.

What are the benefits of DevOps?

The main benefits of DevOps are:

  • Faster time to market - By automating processes and deploying frequently, new features can reach users quickly.

  • Increased productivity - Automation allows teams to focus on higher-value tasks.

  • Higher quality - Through continuous integration and testing, issues are found and fixed earlier.

  • Better visibility - Continuous monitoring provides insights into performance and issues.

  • More agility - Teams can respond faster to changing business needs.

  • Lower costs - Fewer issues and less time spent on manual tasks lead to cost savings.

What tools are used in DevOps?

Common DevOps tools include:

  • Configuration management tools: Ansible, Chef, Puppet

  • Infrastructure as code tools: Terraform

  • Containerization: Docker

  • Continuous integration: Jenkins, GitLab CI

  • Monitoring and logging: Nagios, Splunk, Datadog

  • Source control: Git

These tools help automate and integrate the various DevOps practices. Many other tools in the market can be used as an alternative.

Hope this helps! Let me know how can I improve my future articles.
