The core operations of DevOps are:

• Development: This phase involves the planning and coding of the software. The vision of the project is decided during the planning phase, and the developers begin developing the code for the application.
• Continuous integration (CI): CI is a practice that involves integrating code into a central repository frequently. This helps to identify and fix bugs early on.
• Continuous delivery (CD): CD is a practice that involves delivering software to production on a regular basis. This helps to get new features and bug fixes to users quickly.
• Continuous monitoring (CM): CM is a practice that involves monitoring the performance and health of systems in production. This helps to identify and fix problems early on.

These operations are carried out by DevOps teams, which are typically cross-functional teams that include developers, operations engineers, and quality assurance engineers. DevOps teams work together to automate and streamline the software development and delivery process.

Here is a more detailed description of each core operation:

Development

The development phase of DevOps is where the software is planned and coded. DevOps teams use a variety of tools and techniques to improve the efficiency and quality of the development process. For example, DevOps teams often use agile development methodologies, such as Scrum or Kanban. These methodologies help teams to break down large projects into smaller, more manageable tasks.

Continuous integration

Continuous integration (CI) is a practice that involves integrating code into a central repository frequently. This helps to identify and fix bugs early on. CI tools automate the process of building, testing, and integrating code. This allows teams to get feedback on their code quickly and to make changes as needed.

Continuous delivery

Continuous delivery (CD) is a practice that involves delivering software to production on a regular basis. CD tools automate the process of deploying code to production. This allows teams to get new features and bug fixes to users quickly.

Continuous monitoring

Continuous monitoring (CM) is a practice that involves monitoring the performance and health of systems in production. CM tools collect data on system performance and metrics. This data is used to identify and fix problems early on. CM also helps teams to understand how their software is being used and to make improvements as needed.

DevOps teams use these core operations to deliver software faster, more reliably, and with higher quality. By automating and streamlining the software development and delivery process, DevOps teams can help their organizations to stay competitive and meet the needs of their customers.
