VCS generally refers to Version Control System. It is a method that monitors changes made to the source code of a project in time, allowing collaboration between contributors from different teams and giving a record of the changes. There are many kinds of versions control systems and two major categories: distributed and centralized.

1. GitHub

 2. Bitbucket

 3. GitLab

 4. AWS CodeCommit

The process involves turning sources of code into executable software. It involves creating the code as well as linking libraries as well as packaging binaries, making sure that the program is prepared to be deployed and used.

Continuous integration (CI) is an approach to development wherein developers integrate their code in a repository shared by the developer regularly usually several times per day, in order to identify mistakes quickly. Continuous delivery (CD) enhances CI by automatically deploying the code to production environments for further testing, assuring that the software is consistently released at any point in time.

2. AWS CodePipeline

Continuous Deployment is a variation of Continuous Delivery, where each update that passes automated tests is automatically pushed to production. This reduces the requirement to use manual intervention during the process of deployment, which allows for quick and secure software updates directly to the users at the end of the line.

Infrastructure as Code (IaC) is a process in which infrastructure is planned and maintained with the help of code and automation instead of manual procedures. When you define infrastructure using code, it is made capable of being tested, modified, and repeatable, making it possible to have the same and reliable deployments across various environments.

1. Terraform

2. AWS CloudFormation

Containerization is a lighter method of virtualization, wherein applications as well as their dependencies are packaged into containers to ensure that they are compatible across various environments.

Docker

Orchestration is the term used to describe the automated administration and coordination of containers, generally employing tools such as Kubernetes to manage things like deployment scale, networking, and scaling as well as ensuring the reliable and efficient operations of containerized apps.

Kubernetes

Cloud computing refers to the provision of computing services, including servers databases, storage as well as networking, software and analytics — over the Internet (“the cloud”). This model offers the flexibility of resources, speedier development along with economies of scale which allows companies to access and expand technology resources as needed without requiring significant initial infrastructure investments.

Continuous Monitoring using Prometheus involves the collection and analysis of the metrics of infrastructure and applications in real time to ensure the system’s performance and reliability. Prometheus is an open source monitoring toolkit and alerting system that extracts metrics from the configured targets, then stores them in a database that is time-series, and offers robust query capabilities. This allows for proactive detection of problems in performance, optimization of performance, and prompt response to incidents.

He use of scripting in DevOps involves the use of scripting languages such as Bash, Python, or PowerShell to automate the tasks of the development process. This involves the provisioning of infrastructure, setting up environments, deploying software, in addition to managing workflows. Scripting speeds up processes, improves consistency and helps to implement the concepts that underlie Continuous Integration and Continuous Delivery (CI/CD) by allowing consistent and reliable automation of the operations of DevOps methods.
