Introduction to DevOps : Best practice for combining IT operations and software development

Good Morning Viewers Welcome to my fourth blog. As we know the best practice for combining IT operations and Software development at one place is DevOps . So today we discuss about it , it’s history, evolution and many more . So here we start

What is DevOps ?

This is an acronym used for combination of Development and Operations . It refers to a cooperative strategy that will enable greater communication between an organization’s IT Operations team and Application Development team.

It is a mindset that promotes automation, programmable infrastructure deployment, and iterative software development.

The application must be created, designed, and developed by the development team. The deployment and testing of the application are handled by the operation team. If there are problems with the application, the operation team also provides feedback to the development team.

Building trust and better communication between developers and system administrators is a key component of DevOps. This aids the company in matching technical projects with business needs. The entire team starts to understand that the changes implemented are typically minor and reversible.

History of Devops

Let’s look at some significant events :

• 2007-2008: The idea of this practice develops.
• 2009: The first conference in the early stages was titled “Deploys a Day: Dev and Ops Cooperation of Flicker.” There was also a different conference called “DevOps Days in Ghent, Belgium.”
• 2010: DevOps days conference happened in the United States at mount view, calif.
• 2012: Allana browns at puppet creates a state of it’s report.
• 2014: Publishing the annual “State of DevOps report”.
• 2017: Forrester Research calls 2017 “The Year of DevOps”.
• 2018: 30 DevOps day conferences were scheduled across the united states.

Why we need it ?

We are aware of the issues with traditional models, such as the waterfall model, including the issue of a one-way stream of work, which prevents interaction with consumers and causes the entire process to repeat in the event of a mistake.

Agile has a solution for this that divides the entire development plan into multiple iterations for increased production efficiency. In order to correct errors, the agile approach also incorporates consumer contact with the business. But Agile is also plagued by another issue.

The issue here is when the development team delivers the code to the operations team for testing while continuously changing it for improved performance. However, there might be a delay in the operations team’s feedback if, for example, developers provided code for review late at night, but the project input was delayed because the operations team wasn’t available.

DevOps is the answer to this issue as it is a process or approach in which the development and operations teams collaborate early on with automation. So that they may work on systems that are changing quickly, correct issues, and aid in the timely delivery of high-quality software.

DevOps Architecture:

DevOps is represented as an infinite loop that includes the following steps: plan, code, build, test, release, deploy, operate, and monitor, before returning to the planning stage and continuing.

• Plan – The planning process is crucial in DevOps. All project needs, as well as details like cost, time required for each stage, and other factors, are considered at this point. This will make it easier for team members to understand the project in general.
• Code –Here, the code is written in accordance with the specifications provided by the client. The code in question is broken up into smaller codes called Units. To understand the code clearly, this is done.
• Build –Building of the units is complete at this point. Maven and Gradle are two examples of tools in use.
• Test –At this step, all units are tested. Thus, we will learn precisely where the code contains errors, and if any are discovered, they will be reported.Some of the examples of the tools used are Selenium, PYtest.
• Integrate –All of the code units are integrated at this point. This means that in order to achieve Continuous Integration and Continuous Deployment, we will establish a connection between the development team and the operation team in this stage. Jenkins is an illustration of the tool in use.
• Deploy – The code is now deployed on the environment of the client. AWS and Docker are two examples of tools in use.
• Operate –If necessary, operations are carried out on the code. Examples of tools in use are open shift and Kubernetes.
• Monitor –The client’s environment is where the application is now being monitored.Some of the examples of the tools used are Nagios, elastic stack.

Advantages and Disadvantages of DevOps:

Advantages:

• quicker software delivery times and software development.
• DevOps is versatile and flexible enough to alter with ease.
• When compared to earlier software development approaches, there is less project-related confusion,which improves product quality and productivity.
• The development team and operation team’s divide was filled. In other words, there is now more communication between the teams.
• Automation, which includes continuous integration and continuous deployment, boosts efficiency.
• Increased customer satisfaction.

Disadvantages:

• DevOps is expensive.
• Certain levels of skills are required for maintaining the DevOps architecture.
• Adopting DevOps technology into the traditional style of industries is quite a challenge.

How is DevOps different from Agile?

Applications of DevOps:

United Airlines:

A significant American airline is United Airlines, Inc. This organisation switched from their conventional testing methodology to continuous testing utilising DevOps, which enabled it to save $500,000. Additionally, it boosted code coverage by 85%.

KeyBank:

Cleveland is home to the main KeyCorp subsidiary and regional bank, KeyBank. DevOps was utilised by one bank to integrate security. The procedure practically took one week instead of three months thanks to DevOps.

HP:

The testing of their software presented a challenge for this company. After six weeks of writing the code, bugs are spotted using manual testing, and if any are found, it takes one week to repair them. So they combined the pipelines for Continuous Integration and Continuous Deployment to solve this problem.

Rabobank:

Dutch multinational bank and provider of financial services, Rabobank. DevOps integration has helped one company’s bug count drop by up to 35%. It enabled the business to provide clients with applications more quickly. Regression testing took less time because it had already been tested during development a number of times.

Amazon and Netflix:

These businesses experienced the same issue. They were initially applied to monolithic architecture. But as they expanded, they chose a cloud-based microservice architecture based on AWS to handle the massive volume of traffic.

Summary:

You should now be able to comprehend why we chose it over other software development approaches [like waterfall and agile] now that we have covered all of the foundations in this article. In addition, we reviewed some of the most well-liked applications. I hope that by now you have a better understanding of some of the fundamental ideas on this and why they are important.

As many of these firms embark on their Digital Transformation and Agile Transformation programmes, this is a crucial organizational function and competence that is required. This article provides an overview of what you need to get started with your own DevOps endeavour or advance your current initiative, as well as a summary of the major elements of this. Your engineering and IT departments’ ability to master it will have a direct impact on how well you achieve your business agility objectives.
