Kubernetes

Kubernetes is an open-source container orchestration platform that automates containerized applications' deployment, scaling, and management. It provides a framework for managing containers across multiple hosts, ensuring high availability, scalability, and resilience. Kubernetes abstracts the underlying infrastructure and provides a declarative approach to application deployment, making it a popular choice for managing containerized workloads in DevOps environments.

Microservices

Microservices is an architectural approach where applications are built as a collection of small, independent services that work together to deliver specific functionalities. Each microservice focuses on a single business capability and can be developed, deployed, and scaled independently. This modular approach enables teams to develop and maintain services autonomously, increasing flexibility, scalability, and resilience in complex applications.

Orchestration

Orchestration in DevOps refers to the automated coordination and management of multiple tasks, services, and components to achieve a desired outcome. It involves defining workflows, dependencies, and sequences of actions to ensure smooth execution and Integration across different systems and processes. Orchestration tools enable teams to automate complex deployment, provisioning, and configuration tasks, reducing manual effort and ensuring consistency.

Pipeline

In the context of DevOps, a Pipeline refers to a series of interconnected steps and actions orchestrated to build, test, and deploy software applications. DevOps pipelines automate the software delivery process, enabling teams to achieve continuous Integration and Delivery. They include stages such as code compilation, testing, artifact creation, deployment, and monitoring, ensuring a streamlined and reliable software delivery lifecycle.

Observability

Observability is the practice of gaining insights into a system's internal state and behavior by analyzing its outputs, logs, metrics, and traces. In DevOps, observability is crucial for understanding applications and infrastructure's health, performance, and behavior. Observability tools and practices provide visibility into the system's internals, allowing teams to detect issues, troubleshoot problems, and optimize performance.

Provisioning

Provisioning in DevOps refers to setting up and configuring infrastructure, resources, and dependencies required for application deployment. Automated provisioning involves using infrastructure-as-code tools to define and deploy resources, ensuring consistency and reproducibility across environments. Provisioning can include spinning up virtual machines, configuring networks, and installing required software packages.

Quality Assurance (QA)

Quality Assurance ensures that software products and services meet specified requirements and adhere to predefined quality standards. In DevOps, QA practices focus on integrating quality checks and testing activities into the software delivery pipeline. This includes automated testing, continuous monitoring, and feedback loops to detect and address quality issues throughout the development and deployment lifecycle.

Release Management

Release Management is the process of planning, scheduling, and coordinating the deployment of software releases into production environments. DevOps teams employ release management practices to ensure smooth and controlled software deployments, minimizing user impact and maximizing system stability. It involves release planning, change management, version control, and rollback strategies.

Service Level Agreement (SLA)

A Service Level Agreement is a contractual agreement between a service provider and a customer outlining the expected service level and performance level. In DevOps, SLAs define service and application quality, availability, and reliability targets. They serve as a basis for measuring and monitoring service performance, establishing accountability, and ensuring service delivery meets customer expectations.

Test Automation

Test Automation involves automating the execution of tests to validate software functionality, performance, and reliability. In DevOps, test automation is essential for achieving continuous testing and enabling rapid feedback on code changes. Automated testing frameworks and tools like Selenium or JUnit allow teams to create and run tests automatically, reducing manual effort, increasing test coverage, and accelerating the overall software delivery process.

Version Control

Version Control, also known as Source Code Management, tracks and manages changes to source code files. DevOps teams use version control systems, such as Git or Subversion, to store and track different versions of their codebase, enabling collaboration, maintaining a history of changes, and facilitating easy Integration and rollback of code changes. Version control ensures code integrity, teamwork, and efficient code management in software development.
