What is DevOps?

Basically, DevOps engineers create, test, and maintain the infrastructure and tools that allow for rapid software development and release. DevOps practices seek to simplify the software development process. It is nothing but removing barriers between the development and operations teams. also removing arguments like "In my environment, it worked".

DevOps is the combination of practices and tools designed to increase an organization’s ability to deliver applications and services faster than traditional software development processes. This speed enables organizations to better serve their customers and compete more effectively in the market with a standard framework.

In DevOps, the developers are not taking over operations and doing it themself. It's a misconception that DevOps has also take over the operations but it is just having the part of DevOps not take over it.

Benefits of DevOps?

Improved Collaboration: 

Under a DevOps model, developers and operations teams collaborate closely, share responsibilities, and combine their workflows. This reduces inefficiencies and saves time.

Security:

You can adopt a DevOps model without sacrificing security by using automated, integrated

Rapid Delivery:

When you increase the pace of releases, you can improve your product faster and build a competitive advantage.

Reliability:

Continuous integration and continuous delivery are DevOps practices that can ensure the quality of application updates and infrastructure changes, allowing you to deliver at a faster rate while maintaining an optimal end-user experience.

Speed:

It has become the new currency in the IT industry. The benefits of the “State of DevOps” are being realized. They are more agile, deploying up to 30 times more frequently than their peers. They are more dependable, with up to a twofold increase in success rate.

How DevOps Works?

DevOps works based on workflows and that consist of phases:

Making plans for the next iteration of the product's development

Building the code

Testing and deployment to production environments

Delivering product updates

Software performance monitoring and logging

Getting feedback from customers

What is the difference between the Waterfall Models the Agile Models the DevOps Model?

Waterfall Model:

We have different Models to implement the requirement in the software development life cycle.

The Waterfall Model was the first to be implemented, and it was simple to understand and apply.

Each phase must be completed before moving on to the next, and no phases can overlap.

There is no communication between the requirement gathering team and the developer team, nor between the developer team and the operational team.

Agile Model: 

It is a hybrid of the iterative and incremental process models, with an emphasis on process adaptability and customer satisfaction through the rapid delivery of functional software products.

The Agile Model divides the product into small incremental releases. Iterations of these builds are available.

The Agile Model breaks the product down into small incremental releases. There are iterations of these builds available.

DevOps Model: 

It is the process of strengthening communication between development and operation, as well as selecting the best tools for implementation.

The implementations for the infinite phase take place very efficiently during this phase.

The developer-operation communication improves, and as a result, the life cycle produces an effective result in a short period of time.

What is the difference between DevOps and Site Reliability Engineer?

In contrast to the traditional waterfall approach, DevOps employs agile project development methodologies. DevOps teams are focused on continuous delivery. Iterative delivery of usable digital products is made possible by automation, making it a reality for businesses.

SRE, on the other hand, takes a different approach and allows developers to build the framework as well. The idea came from Google, where an engineer named Ben Treynor was tasked with supervising a team. The team was in charge of increasing the dependability of Google's website. In its analysis, the team concluded that no current architectural method meets the requirements of such large-scale systems.

According to Google, DevOps tells you what to do and SRE tells you how to do it.

How to become DevOps Engineer with RoadMap?

Learn a Programming Language

Any programming language with the skills format, a DevOps Engineer must be efficient in understanding and developing the application concerning the programming language he or she chooses. Python and Java are the best programming languages to use because most scripts are written in Python for automation and Java are the best for understanding programming.

Understand different OS concepts

Understanding Operating Systems and their Distributions The best way is that as a DevOps Engineer, we must be familiar with the terminal, whether it is Linus, Mac, or Windows, and understand the differences between these. Also, having a good understanding of virtual boxes is a plus, because most organizations work on virtual boxes rather than physical machines.

Learn to Live in Terminal

As previously stated in the preceding paragraph, DevOps Engineers must be comfortable with the terminal, scriptwriting, and understanding; operating each and every process in the terminal is the best way; the GUI part is also not recommended; however, almost every time DevOps Engineers operate in terminal only.

Networking and Security

As a DevOps Engineer, you must understand networking. The best way to do this is to understand the ISO Layers, such as where the application is operating, as well as IP Addressing, DNS, DHCP, Static, Default Gateway, SubnetMask, and so on.

What is and how to setup

The majority of our job as DevOps Engineers is to set up the environment. As a result, understanding the architecture is more important than diving into it. In the architecture setup, the DevOps Engineer has more responsibilities.  

Learn infrastructure as code

Teams that use IaC can deliver stable environments quickly and at scale. Teams can avoid manual environment configuration and enforce consistency by representing the desired state of their environments in code. IaC infrastructure deployments are repeatable and avoid runtime issues caused by configuration drift or missing dependencies. DevOps teams can collaborate using a standardized set of practices and tools to deliver applications and their supporting infrastructure quickly, reliably, and at scale.

Learn some Continuous Integration and Delivery(CI/CD) tools

Continuous integration (CI) and continuous delivery (CD) represent a culture, set of operating principles, and set of practices that allow application development teams to deliver code changes more frequently and reliably. The CI/CD pipeline is another name for the implementation. 

One of the best practices for DevOps teams to implement is CI/CD. Because deployment steps are automated, it is also an agile methodology best practice because it allows software development teams to focus on meeting business requirements, code quality, and security.

Learn About Cloud Providers

The cloud provides powerful DevOps services that can cover the entire DevOps life cycle. The majority of its tools and services are compatible with a multi-cloud environment. It includes open source tools such as Terraform, Ansible, Chef, and Packer to help users build their environment quickly.
