DevOps Dictionary

CI Runner What is a CI Runner? A CI Runner is an execution agent responsible for running Continuous Integration (CI) jobs in a CI/CD pipeline. It automates the process of building, testing, and deploying code by executing predefined scripts or commands. CI Runners are commonly used in tools like GitLab...

What is A/B Testing? A/B Testing is a method of comparing two versions of a webpage, app feature, or other product elements to determine which one performs better. By randomly presenting users with different variants (Version A and Version B), A/B testing allows businesses to make data-driven decisions to optimize...

What is an Admission Controller? An Admission Controller is a plugin in Kubernetes that intercepts requests to the Kubernetes API server and evaluates them before they are persisted in the cluster's etcd database. Admission controllers enforce policies and modify requests to ensure they comply with the rules and configurations of...

What is Alerting? Alerting is the automated process of notifying system administrators, DevOps teams, or security personnel when specific conditions or anomalies occur in an IT environment. It is a critical component of monitoring systems, ensuring that teams are informed of potential issues in real time so they can take...

What is Alertmanager? Alertmanager is a component of the Prometheus monitoring stack that manages alerts by deduplicating, grouping, and routing them to appropriate notification channels. It helps teams handle alerts efficiently, reducing alert fatigue and ensuring that only critical notifications reach the right people. How Does Alertmanager Work? Alertmanager processes...

What is Ansible? Ansible is an open-source automation tool used for configuration management, application deployment, and infrastructure provisioning. It allows IT teams to automate repetitive tasks, manage complex deployments, and ensure consistency across environments. Ansible is agentless, meaning it does not require additional software to be installed on managed systems....

An API, or Application Programming Interface, allows different software applications to communicate with each other by defining rules and protocols for requests and responses. APIs play a crucial role in modern software development, enabling integration between systems, services, and platforms. Whether connecting microservices in a cloud infrastructure or building custom...

What is an API Gateway? An API Gateway is a server or application that acts as a single entry point for managing and routing API requests between clients and backend services. It provides essential features such as authentication, request routing, rate limiting, caching, and monitoring. In a microservices architecture, an...

What is an API Gateway? API Gateway is a server that acts as an entry point for managing and routing requests to various backend services in an application architecture. It provides a unified API interface that simplifies communication between clients (such as web or mobile apps) and microservices or other...

What is an Artifact? An Artifact in software development refers to any file or document generated during the software development lifecycle (SDLC). It is often a byproduct of build or deployment processes, such as compiled code, binary files, container images, or configuration files. Artifacts are essential for ensuring consistency and...

What is Artifact Management? Artifact Management is the process of storing, versioning, and distributing binary files, dependencies, and build artifacts generated during software development. It ensures efficient organization, security, and traceability of software components throughout the CI/CD pipeline. How Does Artifact Management Work? Artifact management systems provide a centralized repository...

What is an Artifact Repository? An Artifact Repository is a centralized storage solution used to manage, version, and distribute artifacts generated during the software development lifecycle. Artifacts can include compiled binaries, container images, libraries, configuration files, and other files necessary for building, testing, and deploying software. Artifact repositories play a...

What are Audit Logs? Audit Logs are records that provide a detailed and chronological account of events or activities that have occurred within an application, system, or network. These logs capture actions taken by users, applications, and systems, including login attempts, data access, configuration changes, and other critical activities. Audit...

What is Auto-Scaling? Auto-Scaling is a cloud computing capability that automatically adjusts computing resources based on workload demand. It ensures optimal performance, cost efficiency, and availability by dynamically adding or removing resources in response to traffic fluctuations. How Does Auto-Scaling Work? Auto-scaling continuously monitors system metrics and applies predefined scaling...

Automation in the context of DevOps refers to the process of using technology to perform tasks and processes in the software development lifecycle without manual intervention. It plays a critical role in enabling the continuous integration, continuous delivery (CI/CD), and deployment of software, as well as improving collaboration between development...

What is an Autoscaler? Autoscaler is a tool or service in cloud computing that automatically adjusts the number of resources, such as virtual machines or containers, in response to changing demand. The autoscaler monitors the performance and load of an application or infrastructure and scales resources up or down based...

What is Autoscaling? Autoscaling in Kubernetes is the process of automatically adjusting the number of running pods or nodes in a cluster based on workload demand. It ensures that applications have enough resources to handle increased traffic or processing needs while scaling down during periods of low activity to save...

What is an Availability Zone? Availability Zone is a distinct, isolated data center or group of data centers within a cloud region, designed to provide high availability and fault tolerance for applications and services. Each Availability Zone (AZ) is geographically separated from others within the same region, but they are...

What is AWS? Amazon Web Services (AWS) is a cloud computing platform that provides a wide range of infrastructure services, including computing power, storage, databases, networking, and machine learning. AWS enables businesses to build, deploy, and scale applications without maintaining physical hardware. How Does AWS Work? AWS operates as a...

What is Azure? Azure is a cloud computing platform and service provided by Microsoft. It offers a wide range of cloud-based solutions, including virtual machines, databases, AI, networking, and security services, allowing businesses to build, deploy, and manage applications across multiple environments. How Does Azure Work? Azure provides a scalable,...
