DevOps Course And Certification

What is DevOps?

DevOps is a development culture that enhances and promotes the collaboration between the development and operations team of an organization to deploy codes to production faster in a repeatable and automated way. The word 'DevOps' is a combination of two words which are 'Development' and 'Operations.' 

DevOps serves to increase an organization's speed to deliver software applications and services. It allows businesses and organizations to serve their customers better and to compete with their market competitor more strongly. 

In more simple terms, DevOps can be defined as the alignment of the IT development and operations team for better collaboration and communication. 

Under a DevOps model, the development and operations teams are no longer 'distant'. In some cases, these two teams are joined together into a single team where the engineers work across the whole application lifecycle, from the initial development and test to the deployment stage, then to operations, and they develop a range of skills that are not limited to a single function.

In some models of DevOps, the quality assurance teams and the security teams might also become more tightly integrated into the development and operations team throughout the application production lifecycle. When security is the focus of everyone that is on a DevOps team, they are then referred to as 'DevSecOps'. 

These teams make use of several practices to automate various processes that in the past, have been manual and very slow. They make use of a technology stack and tooling which helps them to operate and evolve applications reliably and quickly. These technology stack tools also help software engineers to individually accomplish several tasks that normally would have required help from other teams, and this further increases the team’s speed.

History of DevOps

The DevOps era started to form between the years 2007 and 2008 when Information Technology operations and software development nations began to talk about what they felt was a real high level of dysfunction in the industry.

They were against the regular software development model, which made the people who write code to be separated organizationally and functionally from those who support and helped deploy code.

Developers and Information Technology Ops professionals had quite separate and always competitive objectives, different department leadership, different KPIs(key performance indicators) in which they were assessed, and also worked on different floors or even different offices. The result was isolated teams that were only bothered with their territories, long hours, bad and careless releases, and also very unhappy customers.

But then there's a much better and effective way to carry out these activities, they said. So the two separated professions or rather communities came together and started discussing – with folks like the great Patrick Dubois, Gene Kim, and John Willis at the forefront of the conversation.

What kicked off in online forums and local meet-ups is now a major factor in the software defining operation. You and your entire team are feeling the pain caused by separated teams and dead systems of communication within your company. You’re making use of the agile methodologies for structuring, planning, and even development, but still struggling to release your code without a series of mistakes, bugs and even drama per se. 

The good news is that DevOps isn’t magic, and these changes don’t happen overnight. Another good news is that you don’t have to wait for the management at the top to bring out a large-scale initiative. By getting and understanding the value of DevOps and making small, continuous changes, your team can strat on the DevOps journey right away. 

Features of DevOps

There are lots of features of DevOps, and some of them are:

1. DevOps Provides Collaboration between the development and the operations teams.

2. DevOps helps to develop applications that are easily scalable.

3. DevOps helps in automating the workflow.

4. DevOps helps in continuous building, testing, integration, and deployment process.

5. DevOps helps in the speedy delivery of new features and in reducing the cost of IT. 

6. DevOps helps to increase customer Satisfaction & Retention and Business Efficiency.

Benefits of DevOps

There are lots of benefits of DevOps, and some of them are:

1. Predictability: DevOps offers a more obviously lower rate of failure of new releases

2. Reproducibility: DevOps helps to version everything so that an earlier version can be restored anytime that you want.

3. Maintainability: Devops helps with the process of recovery in the event of a new release disabling or crashing the current system.

4. Time to market: DevOps reduces the time spent to release the product by up to 50% by following a more streamlined software delivery process. This is particularly the case for mobile and digital applications.

5. Greater Quality: DevOps helps the development team to provide an improved quality of application development as it combines infrastructure issues.

6. Reduced Risk: DevOps includes various security aspects into the software delivery lifecycle. It helps in the decrease and reduction of defects across the application lifecycle. 

7. Breaks larger code base into small pieces: DevOps is based on the agile software programming method. Therefore, it allows you to break larger codebases into very small and manageable chunks that can help with understanding the application.

8. High Pay Grade: DevOps Engineers are one of the highest-paid in Tech, so learning DevOps is a very wise investment and this course helps you learn it.

9. Collaboration and Trust: Culture is the number one factor of success in DevOps. Building a team where responsibility is shared, there is transparency and a faster feedback process is the base of every high performing DevOps team.

10. Release faster and work smarter: Speed is a major factor in everything. Software Development Teams that carry out DevOps release more often, with a higher quality of software and stability

11. Accelerate time to resolution: The team with the fastest resolution is the team that succeeds. Totally Full transparency and stress-free communication enable teams that practice DevOps to reduce server downtimes and fix issues faster than they have ever done.

12. Management: DevOps helps teams to manage unplanned work properly.
