What is DevOps ?

 What is DevOps?

Few years ago, developing a software was a very long and effort-taking process, especially with the barriers and poor communication between development team and operations team in the company, there was no flexibility to change the requirements after the planning phase is over. Also, both of the developers and operators could work on different environments so if a bug occurs with the operations team, developers would say it is worked well on their dev setup.

After that DevOps has been created in 2009 by Patrick Debois, a software development consultant. 

Now let me explain what the meaning of DevOps is before we dive in its benefits;

DevOps consistent of two words, Dev = Development and Ops = Operations. According to Microsoft definition; Teams that adopt DevOps culture, practices, and tools become high-performing, building better products faster for grater customer satisfaction. 

This improved collaboration and productivity is also integral to achieving business goals like these:

1- Accelerating time to market 

2- Adapting to the market and competition 

3- Maintaining system stability and reliability

4- Improving the mean time to recovery

In different words, DevOps integrates developers and operations teams in order to improve collaboration and productivity by automating workflows and continuously measuring application performance. 

We can divide the benefits of DevOps into 3 categories:

• Technical benefits: 

1. Continuous Software Delivery: With DevOps the team will be always ready to “delivering any time” to the production while they deliver smaller increments of the code every time.

2. Less complexity to manage: The ability to merge multiple teams makes the management process easier.

3. Faster resolution of problems: As mentioned above, with DevOps there are smaller code to deliver every time, so the problem will be more specific and smaller which gives developers the ability to solve problems faster.

• Cultural Benefits:

1. Happier, more productive teams: Employee will feel better if they finish small task every week than finish the whole project after a year, and this will level up their productivity.

2. Higher employee engagement: In the traditional way of development there were walls and poor communications between teams so the employee engagement was low, but after DevOps team members have to connect more with each other not to mention communication with other teams.

3. Greater professional development: Teams are able to have shorter development cycles, reduce implementation failures, and overall enhance communication within the team.

• Business Benefits:

1. Faster delivery of features: These days, building and releasing better products in the market is not enough for businesses to stay ahead of the competition. Organizations need a DevOps approaches to meet the demands of time-to-market features.

2. More stable operating environments: To maintain a stable environment, Infrastructure as a code (laC) can be used. Server configuration is stored in the source code repository with the application source. Automation tools will take the configuration and apply each task to the desired system. These tools automate any task virtually and are easy to learn.

3. Improved communication and collaboration: The more integrated and familiar the team members with each other, the less costly communication has to be – a benefit that helps everyone involved in the production process.
