VCS typically stands for Version Control System. Version control is a system that manages changes to a project's source code over time, enabling collaboration among multiple contributors and providing a history of changes. There are different types of version control systems, with two main categories: centralized and distributed.

1. GitHub

2. Bitbucket

3. GitLab

4. AWS CodeCommit

Software build is the process of converting source code into executable programs. This involves compiling the code, linking libraries, and packaging the binaries, ensuring that the software is ready for deployment and use.

1. Maven

2. AWS Build

Continuous Integration (CI) is a development practice where developers integrate code into a shared repository frequently, ideally several times a day, to detect errors quickly. Continuous Delivery (CD) extends CI by automatically deploying the integrated code to production-like environments for further testing, ensuring that the software can be reliably released at any time.

1. Jenkins

2. AWS CodePipeline

Continuous Deployment is an extension of Continuous Delivery where every change that passes automated tests is automatically deployed to production. This practice eliminates the need for manual intervention in the deployment process, allowing for rapid and reliable software releases directly to end users.

1. Ansible

2. AWS CodeDeployment

Infrastructure as Code (IaC) is a practice in which infrastructure is provisioned and managed using code and automation rather than manual processes. By defining infrastructure in code, it becomes versionable, testable, and repeatable, enabling consistent and reliable deployments across different environments.

1. Terraform

2. AWS CloudFormation

Containerization is a lightweight form of virtualization where applications and their dependencies are packaged together into containers, ensuring consistency across different environments.

Docker

Orchestration refers to the automated management and coordination of these containers, typically using tools like Kubernetes, to handle tasks such as deployment, scaling, and networking, ensuring efficient and reliable operation of containerized applications.

Kubernetes

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, and analytics—over the internet ("the cloud"). This model provides flexible resources, faster innovation, and economies of scale, allowing businesses to access and scale technology resources on-demand without the need for significant upfront infrastructure investments.

Amazon Web Services

Microsoft Azure

Continuous Monitoring with Prometheus involves collecting and analyzing metrics from applications and infrastructure in real-time to ensure system performance and reliability. Prometheus is an open-source monitoring and alerting toolkit that scrapes metrics from configured targets, stores them in a time-series database, and provides powerful querying capabilities. This enables proactive detection of issues, performance optimization, and timely incident response.

Scripting for DevOps involves using scripting languages like Bash, Python, or PowerShell to automate tasks throughout the software development lifecycle. This includes provisioning infrastructure, configuring environments, deploying applications, and managing workflows. Scripting accelerates processes, enhances consistency, and supports the principles of Continuous Integration and Continuous Delivery (CI/CD) by enabling repeatable and reliable automation of operations in DevOps practices.
