Why Should You Learn DevOps in 2023??
DevOps is the final frontier of the software development life cycle (SDLC). DevOps is derived from Agile SDLC Model and addresses the gap between Developers and Operations.?
        

What is DevOps and How does DevOps work?

DevOps, as a model of software development, allows a single team to manage the entire development life cycles, which are development, testing, deployment, and operations.

DevOps aims to shorten the development life cycle by focusing on collaboration, and integration between developers and other roles such as testers, security, or system administrators.

As is now known, since the beginning, software development has become under extremely uncompromising boundaries of the Waterfall Model, which caused it to become insufficient and a burden until the end of the millennia. Waterfall uses the theory that what you plan at the beginning is what you get at the end. This might be true for the Model T assembly line but not for the software development process. Even if you manage to get the planned outcome, it may no longer be relevant or up-to-date.

That is why,? 17 software practitioners came together, wrote the Agile Manifesto, and introduced 12 principles of the new SDLC era in 2021. According to agilemanifesto.org, the Agile Alliance, that is what they call themselves, is the home of the original document and intended to create and support a work environment that focuses on the business objectives and can respond and pivot quickly according to the users and market needs.?

This was a giant step but not enough. In 2008, Patrick DuBois and Andrew Clay Schafer tried to reshape the “Agile Infrastructure” at the “Agile 2008 Conference”, and a new concept, DevOps was born.[2]

According to Amazon,?

DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.

The four main DevOps principles are:

• Create production-like systems for the development and testing environment
• Ensure a reliable and repeatable process with iterative and frequent deployments
• Continuously monitor and validate operational quality characteristics
• Amplify feedback loop

The four main advantages of DevOps are as follows:

• Time taken to create and deliver software is reduced
• The complexity of maintaining an application is reduced
• Collaboration between developers and the operations team is improved
• Continuous integration and delivery ensure faster time for the market

Who is a DevOps Engineer? What does a DevOps Engineer Do?

A DevOps engineer is the key team member of an IT company, who is responsible for shortening the software development life cycle (SDLC) duration by focusing on collaboration, and integration between or within the teams. DevOps engineers ensure the continuum of development by automating the process. DevOps engineer uses exceptional tools for build, version control, configuration management, project management, and automation.?

Continuous Integration-Continuous Delivery (CI/CD) is the main focus for a DevOps Engineer. Building a pipeline and performing tasks repetitively and continuously creates integration. Deploying the application from the development server to the production server and operating, and monitoring the releases provides Continuous Delivery.

• Network and Security: TCP/If Fundamentals, Protocols, DNS, FTP, SSL…
• Servers: Web servers, Caching, Databases.
• Infrastructure as code (IaC): Configuration management, Container, Container orchestrators, infrastructure provisioning.
• CI/CD: Jenkins, Gitlab…
• Monitoring: Prometheus, Grafana, Zabbix…
• Clouds: AWS, Azure, GCP…

The tools are processes in DevOps and are not limited to those mentioned. You can choose a self-thought path or get help.
