DevOps: An Infinity Loop

What is DevOps:

DevOps is the combination of best practices, philosophies that bridges the gap between Development (Dev) and Infrastructure (Ops) teams. This enables an organization’s ability to build, test, and release software’s, services much faster and reliable as compared to the traditional approach where both teams use to work in siloes.

It helps an organization to gain customer trust and provide better response to customer needs.

DevOps Culture:

Adapting to DevOps philosophies requires a change in mindset.

One of the most important parts of the implementation of healthy DevOps culture is the collaboration between the Dev and Ops teams instead of pointing finger at each other. The collaboration is not limited to only two teams but extends to all the stakeholders who are involved in the delivery of the software or service i.e. all teams, including test, product management, etc.

All stakeholders play a significant part and take ownership of additional phases i.e. beyond their stated roles example development teams invite operations teams in their planning sessions.

DevOps Practices:

Every organization has its unique way of dealing with things on its own, hence there is no single path to DevOps transformation instead there are multiple paths which one can choose. Below are few important DevOps practices:

  • Continuous Integration: It’s a practice in which developers repeatedly merge their code to a central location (repository usually Git). It involves automated building and testing which aims to fix the bugs thereby improving software quality. Some examples of famous CI tools are Jenkins, GitLab CI, Circle CI, TeamCity, etc.
  • Continuous Delivery: It’s a practice in which code changes are built, tested, and deployed to the production environment in an automated fashion. It allows for delivering better software because code is tested in lower environments. There is another concept Continuous Deployment with one exception that deployment to Production happens automatically without explicit approval.
  • Infrastructure as Code: It’s a practice in which Infrastructure is managed and built using code. Usually, all the code is stored in a version-controlled system. It helps to avoid manual error, for complex infrastructures because code can be validated and audited. Read more.
  • Configuration Management: It’s a practice in which the state of IAAS (Infrastructure as a Service) components like Servers, Virtual Machines, Databases, etc. are managed. These kinds of tools help in rolling out new changes in an organized fashion thereby maintaining consistency among the components. Some examples of famous CM tools are Ansible, Puppet, Chef, etc.
  • Continuous Monitoring: Monitoring plays a crucial role because services must be available 24/7. Hence alerts and logging should be enabled to ensure the smooth running of services. This will help the DevOps team to mitigate the issues and improve the availability, performance.
  • Collaboration: When different teams work together, goals become more aligned thus achieving a higher success rate. It allows each member of the team to contribute their expertise for the benefit of a common objective. Therefore, collaboration is one of the key aspects of DevOps.

Benefits of DevOps:

  • Improved customer experience and satisfaction.
  • Faster delivery time to market.
  • Bid adieu to defects.
  • More stable software.
  • More Productivity among teams.

These are very few benefits of adopting DevOps practices and the fact is DevOps is the future of Production releases.
