Argo CD

GitOps continuous delivery tool for Kubernetes that syncs deployments from Git and alerts on configuration drift.

AWS

AWS is Amazon’s cloud platform providing on-demand compute, storage, networking, and managed services for building and running applications.

AWS App Mesh

AWS App Mesh controls service-to-service traffic for microservices on AWS with routing, observability, and resiliency policies.

AWS IoT

AWS IoT securely connects devices to AWS, enabling telemetry ingestion, processing, and remote device management.

AWS Lambda

AWS Lambda runs code on AWS in response to events, automatically scaling without server management for APIs and background processing.

Backstage

An open-source framework for building an internal developer portal where teams can find services, docs, and tools in one place.

Branching

Creating a separate copy of the code so people can work on changes without messing up the main version, then merge it back when it’s ready.

Chaos Engineering

Chaos Engineering is a practice of safely injecting failures into a system to observe its behavior and improve reliability.

CI/CD Pipeline

A CI/CD pipeline is an automated workflow that builds, tests, and deploys code changes through repeatable checks before release.

Cloud

Internet delivered compute, storage, databases, and networking services that run workloads without managing on premises infrastructure.

Container

A lightweight package that bundles an app with everything it needs so it runs the same way anywhere.

Container Registry

A central place to store, version, and share container images so apps can be pulled and run anywhere.

Continuous Delivery

Continuous Delivery automates testing and release readiness for each code change, enabling frequent, reliable deployments with minimal manual effort.

Continuous Integration

Frequent merges to a shared branch with automated builds and tests to detect integration problems early.

Custom Resource Definition (CRD)

A Kubernetes API extension that lets you define new resource types so you can manage your own custom components like built-in Kubernetes objects.

DAST (Dynamic Application Security Testing)

Automated security testing that attacks a running app from the outside, like a hacker would, to find vulnerabilities.

Development Environment

Isolated workspace for building, running, and testing software changes safely before deploying to shared or production environments.

DevOps

Practices and culture aligning development and operations to automate delivery, improve reliability, and speed up software deployments.

Docker

A tool that packages an app and everything it needs into a small, isolated container so it runs the same anywhere.

DORA Metrics

DORA Metrics are four delivery measures tracking deploy frequency, lead time, change failure rate, and recovery time.
