DevOps Tutorial – Why and How?

Let’s go through DevOps so that it will be easier for you to understand.

DevOps is the combination of social opinions, exercises, and tools that increase an organization’s capability to deliver applications and services through high speed: growing and developing products at a faster speed than organizations using old software development and base management methods. This speed allows organizations to better assist their customers and fight more efficiently in the market.

The word ‘DevOps’ is a blend of two words ‘development’ and ‘operations.’

Why is DevOps needed?

•    Before DevOps, the development and operation team worked in total separation.

•    Examination and Deployment were secluded actions done after design-build. Hence they wasted more time than actual build cycles.

•    Without DevOps, team members are spending a huge quantity of their time in testing, using, and creating instead of building the project.

•    Old-fashioned code deployment leads to human mistakes in production.

•   Coding & operation teams have their variant timelines and are not in similar to creating additional delays.

DevOps Lifecycle:

Understanding DevOps is not conceivable without acknowledging DevOps lifecycle.

Here is a brief description of the DevOps life-cycle:

•    Development: The development of software takes place regularly. In this phase, the complete development process is divided into small improvement cycles. This helps DevOps team to speed up software development and distribution process.

•    Testing: Quality Assurance (QA) team use tools like Selenium to distinguish and fix glitches in the new piece of code.

•    Integration: New functionality is mixed with the general code, and testing takes place. Constant development is only possible due to constant combination and testing.

•    Deployment: The process takes place continuously. It is conducted in such a manner that any alterations made any time in the code should not influence the functioning of huge traffic website.

•    Monitoring: Operation team takes care of the unsuitable system performance or bugs which are found in production.

Benefits of DevOps:

Speed: Move at high speed so you can innovate for customers quicker, adapt to changing markets better, and grow more effective at accelerating business results. The DevOps model enables developers and operations organizations to accomplish these results. For example, microservices and constant delivery let teams take control of services and then deliver updates to them faster.

Rapid Delivery: Increasing the frequency and step to release so you can innovate and enhance your product quickly. The quicker you release new features and fix bugs, the faster you can return to your customers’ needs and develop a competitive choice. Continuous integration and continuous delivery are practices that automate the software release process, from build to deploy.

Reliability: Guarantee the quality of application updates and support changes so you can probably deliver at a more rapid speed while keeping a positive experience for end users.

Scale: Performing and maintaining your infrastructure and improvement processes at scale. Automation and flexibility help you manage multiple or improving systems efficiently and with decreased risk. For example, infrastructure as code helps you manage your development, testing, and production environments in a repeatable and more productive manner.

Improved Collaboration: DevOps emphasizes benefits such as ownership and responsibility. Developers and operations organizations cooperate closely, assign many responsibilities, and attach their workflows. This decreases incapability and saves time (e.g. handwork is reduced between developers and operations, writing code that takes into account the environment in which it is run).

Security: Move swiftly while maintaining control and protecting compliance. Choosing DevOps without falling security by using automatic methods, fine-grained commands, and configuration management systems. For example, utilizing infrastructure as code and policy as code, you can determine and then track compliance at scale.

Evolution of DevOps:

•    In the year 1957, the notion of DevOps began with the evolution of the first computer program code.

•    After launching ARPANET, network of engineering jobs and network operations services were designed in the year 1967.

•    Moving ahead to 2003, the first set of “site loyalty engineers” was hired to operate a creative atmosphere that was separate from the development environment.

•    Few years below the way, in 2009 Flickr combines “Dev” and “Ops” in a trial to determine the ‘finger pointing’ query connecting the developers and operations organization.

•    Again in 2009, an engineer named Patrick Debois arranged a small gathering of “agile system administrators.” It means to promote for his conference on Twitter, he created a compressed hashtag, thus giving birth to the term “DevOps.”

•    Today, Artificial Intelligence (AI) penetrated in our lives. DevOps evolves with manta to ‘ automate, automate and automate.’

Is DevOps Agile?

The simple answer to it is “No”. Though both the words are broadly similar, it would be inaccurate to say that they are both the same. While DevOps is the notion to manage end-to-end engineering methods, Agile is a method used to execute complex projects. In fact, Agile is one of the crucial parts of successful DevOps. Here are a few essential differences.

DevOps is essentially reducing how Dev and Ops are done today. And it will improve how security is done, too. It demands new skills, new tools, and a new set of preferences. It will take time and a new viewpoint. So the sooner you get started, the better.
