The Untold Story and Mystery Behind DevOps Success | iCert Global

DevOps has two aspects, similar to two brothers who might not always agree. DevOps is a new approach to developing software where operations teams and developers collaborate very closely with each other. They try to get the software running without any problems. Most software teams today employ DevOps because it enables companies to create quality software and release it onto the market faster.

DevOps is a term derived from 'development' and 'operations' as per Wikipedia. It is the methodology through which software development, operations, and services interact with each other. DevOps is all about coordination, collaboration, and distributing tasks among software developers and IT operations personnel. In 2019, it was asserted that more individuals desired DevOps certifications, particularly due to the advent of Generative AI.

This is how development (Dev) and operations (Ops) work:

Dev wants:

• Constant changes
• New features released rapidly

Ops goals:

• Steady and stable systems

• Carefully designed new services

The problem is that Dev and Ops typically don't see eye to eye. Dev wants to release updates in a rush, while Ops wants the software stable with few changes.

There are three significant differences between Development and Operations:

1. Goals gap: They want different things.

2. Process gap: They possess various change handling and release processes.

3. Tools gap: They use various tools to complete their task.

Due to these variations, Dev and Ops will mostly work independently, such as two separate teams.

The issue is:

• Dev wishes to implement numerous changes rapidly.
• Ops desires to avoid change in order to remain stable.

Is DevOps the solution?

DevOps bridges operations and development. It ensures teams work more effectively together and draws ideas from Agile software development. DevOps practitioners are likely to be aware of the work of both fields.

Why DevOps?

DevOps is not a process or best practices. Rather, it's a set of ideas that assist in minimizing barriers between teams. DevOps revolves around four key areas: Culture, Automation, Measurement, and Sharing (or CAMS).

Culture:

People and how they work together matter most in DevOps. Automation is not going to work if there isn't good culture.

Engage early, engage often

Discuss. Discuss among yourselves often. Start the project ahead of time.

Break silos

Bring the walls down between groups so that all can work together.

Be receptive to alternatives

Be ready to discuss several potential methods of resolving problems.

Don't blame.

Focus on fixing problems instead of blaming.

Other most important aspects of DevOps culture are:

• Discuss with colleagues
• Involve all in important decisions

• Inquire if you don't get it.
• Never say "never" — be open to having new ideas.
• Have daily brief meetings with all included

Automation

After your team has a good culture, you can introduce automation. Automation is performing tasks automatically with the help of tools and machines. There are some tools that help in making releases of software, installing systems, managing configurations, monitoring systems, and controlling processes. These tools help in making DevOps work more effectively.

Why use automation?

• Machines can repeat the same work over and over without breaking down.
• It makes it clear and consistent
• It is faster and time-saving.
• For instance, saving 10 minutes each day is more than 2 days per year!

What can be automated?

• Making software
• Releasing new versions
• Checking the software
• Monitoring systems
• Automatically solving problems
• Rolling out systems

• Systems configuration

Measurement (Metrics)

You can't optimize what you can't measure. Great DevOps teams measure everything frequently:

• Towards which direction the system is heading
• How the process is proceeding
• How individuals are working
• Measurement assists with:
• Planning for future needs
• Identifying patterns over time
• Problem-solving and discovery

For instance, monitoring website access statistics and graphing it against time aids in monitoring performance.

Sharing

Sharing is the last stage of CAMS. Proper DevOps culture fosters sharing concerns and ideas. Free sharing leads to:

• Better ideas
• Improvement in work
• Providing key information and statistics

Examples:

• Operations provides developers with access to the systems
• Developers share new technology ideas

DevOps Lifecycle

The DevOps lifecycle is a sequence of actions that enables teams to develop, test, and release software faster and more effectively. It connects development (Dev) and operations (Ops) in such a way that they work well together.

These are the primary steps:

1. Develop

Developers create the code for the software.

2. Build

The code becomes a working program or app. This step ensures the code works well together.

3. Test

The program is checked for defects or faults. This makes it function optimally.

4. Release

The software is provided to consumers. It entails making it accessible to customers so they can utilize it.

5. Deploy

The software is installed on servers or computers to run.

6. Operate

The program is regularly tested to make sure that it operates correctly at all times.

7. Monitor

They try out how well the software functions and where there are issues. They utilize this to improve the software.
