DevOps Tutorial Guide for the Beginners

DevOps word in itself is a combination of two words one if Development and other is Operations. It is neither an application nor a tool instead is just a culture to promote development and Operation process in a collaborative manner. As a result of DevOps implementation, the speed to deliver application and services is increased. DevOps Tutorial Due to DevOps, the organizations become able to serve their customers strongly and in a better way in the market. In other words, we can say that DevOps is the process of alignment of IT and development operations with better and improved communication.

Here is what we cover in the DevOps Tutorial Guide

What is DevOps?

As per application economy today, business has become software businesses and DevOps has become one of the most valuable business disciplines for the enterprises. With the help of DevOps, quality and speed of application delivery have been improved a lot.

DevOps is all about the integration of operations and development process. Organizations that have adopted DevOps noticed 22% improvement in software quality and 17 percent improvement in application deployment frequency that results in 22 percent hike in customer satisfaction and 19 percent revenue hikes as a result of the successful DevOps implementation.

Why is DevOps needed?

As it has been clear so far that DevOps implementation has increased the rate of software delivery and the revenue for business stakeholders. Following listed reasons are the most considerable ones for DevOps implementation due to which business organizations prefer its implementation:

  • Before DevOps implementation, operation and development teams worked in an isolated
  • Testing and Deployment activities mostly were performed in an isolated manner after design-build step and they took more time than actual project completion time.
  • Before DevOps implementation, team members usually spend a large amount of time in deploying, testing, designing, and building the projects
  • Human production errors were deployed during manual code conduction.
  • Operations and coding teams generally had different timelines and do not have proper synchronization that results in further delay.

To avoid above-mentioned hassles and noncollaborative performance measures, a successful implementation of DevOps is needed.

What is Future Scope of DevOps?

Continuous integration and delivery are offered by the DevOps. It makes the product delivery cycle quicker and enterprises become able to launch the software timely without compromising its quality. DevOps Tutorial Following are the factors that will improve as a result of DevOps implementation:

  • Predictability: DevOps decreases the failure rate of new product releases.
  • Maintainability: The process improves the overall recovery rate at the time of release event.
  • Improved Quality: DevOps improves the quality of product development by incorporating infrastructure issues.
  • Lower Risk: Security aspects are incorporated in SDLC and the number of defects gets decreased across the product
  • Cost Efficient: Cost efficiency is improved due to DevOps that is always an aspiration of every business organization.
  • Stability: DevOps implementation offers stable and secure operational state.
  • Streamlined Delivery Process: As DevOps provide streamlined software delivery so marketing effort is reduced up to 50%. It happens due to mobile application and digital platform.

DevOps Lifecycle Phases Plan And Measure

DevOps is basically an integration of development and operation process. One cannot implement DevOps without understanding its lifecycle. Following steps are included in the DevOps lifecycle: DevOps Tutorial

DevOps Lifecycle Phases: Development

This is the first stage of DevOps lifecycle in which development of application takes place constantly. The entire development process is broken down into small steps or development cycles. As a result of this, the speed of software development and delivery is increased.

DevOps Lifecycle Phases: Testing

Selenium like testing tools is used to speed up the overall testing process by quick identification of errors and fixing the bugs.

DevOps Lifecycle Phases: Integration

New functionalities are integrated with the prevailing code and testing of new code takes place. Continuous integration and testing help in the continuous development process.

DevOps Lifecycle Phases: Deployment

Continuous deployment is the part of DevOps lifecycle. When it is performed in the right way then it can affect the overall functioning of high traffic website.

DevOps Lifecycle Phases: Monitoring

Inappropriate system behavior is managed by monitoring. Through proper monitoring, the bugs are found and fixed in a hassle-free way.

These are the building blocks for any DevOps application. Various tools are used to optimize the various stages of Software application development. As per DevOps culture, a group of Engineers is responsible for each stage of DevOps application development step including developer, system admin, testing, and others.

How DevOps Improve Development And Operation Process?

DevOps solves development challenges in following ways:

  • Code deployment time is reduced because of the faster testing process and speedy feedback mechanism.
  • Developers do not feel work pressure and can build new code in less time.

As far as operation process execution is concerned then implementation of DevOps improves the operation processes in the following ways:

  • Configuration management helps the organization to execute and organize the configuration plans and they become able to manage their infrastructure in an effective
  • Containers and virtualization concepts provide a simulated environment to increase software reliability and maintain uptime of the production environment.
  • Effective and improved server monitoring is offered. As a result of this, proper feedback can be provided and effective administration is assured.

Following DevOps Tools Are Used To Offer Improved Performance

DevOps Tutorial You can explore more about above-listed DevOps tools (Puppet, Chef, Sensu, Nagios, Bamboo, Eclipse, Git, Saltstack, Jenkins ) that are used to provide improved performance by DevOps team. DevOps tools are used to improve the developer’s efficiency.

7 Signs that Show You Need DevOps

Developers and Operation engineers are two different organizational teams and if these teams are found to be on a wrong track that it signifies that you need DevOps. We have consolidated here seven signs that can help you in getting the answer that whether you need DevOps or not:

  • The development team is not able to detect software defects at the early age of its development
  • Agile methods are used to speed up software development process but as soon as the application goes to production department all methods become ineffective
  • Testing and development team members are not able to access resources timely and so the development process delays
  • You are not able to identify exact problems of development, testing, and production department
  • Simple human errors are often creating hurdles during development and deployment process.
  • Once the app is in production, developers think that their job is over.
  • At the time of the problem, both development and operation teams start blaming each another.

What is the Future Career Scope of DevOps engineers?

If we will see then we can notice then a lot of changes will occur in DevOps process in the near future and some of them are like organizations are shifting their needs from years to weeks and months and for IT people it has become one of the most in-demand skill. We can even expect continuous improvement in DevOps process. It is obvious that before DevOps implementation teams were working in an isolated manner and it has provided a collaborative environment to the teams.

Various tools are evolving to make the process smoother. DevOps engineers will have more control and access to the end user product. So, DevOps is definitely a wonderful choice for the organization in terms of product deployment, quality management, and operations handling etc.
