GCP DevOps refers to the practice of implementing DevOps principles and practices using Google Cloud Platform (GCP) services and tools. DevOps is a set of practices that combines software development (Dev) and IT operations (Ops), aiming to shorten the systems development life cycle and provide continuous delivery with high software quality. GCP offers a range of cloud services that support the automation, collaboration, integration, and speed that DevOps emphasizes. These services facilitate various DevOps processes including but not limited to:

1. Source Code Management: Google Cloud Source Repositories provide fully-featured, scalable, private Git repositories hosted on Google Cloud.

2. Continuous Integration/Continuous Deployment (CI/CD): Cloud Build offers capabilities for building, testing, and deploying software quickly across all languages and Google Cloud environments. It integrates seamlessly with other GCP services to automate the deployment of applications to services such as Google Kubernetes Engine (GKE), App Engine, Cloud Functions, and Firebase.

3. Containerization and Orchestration: Google Kubernetes Engine (GKE) is a managed environment for deploying, managing, and scaling containerized applications using Google infrastructure. The orchestration and management of containers are crucial in DevOps practices for ensuring application portability and efficient scaling.

4. Infrastructure as Code (IaC): Deployment Manager and Terraform support for Google Cloud allow teams to automate the provisioning of Google Cloud resources in a repeatable and predictable manner, following the IaC principle.

5. Monitoring and Logging: Google Cloud’s operations suite (formerly Stackdriver) provides integrated monitoring, logging, and diagnostics. These tools help DevOps teams gain insight into how software performs in production, understand its health, and respond to issues in real-time.

6. Security and Compliance: GCP provides various tools and features to ensure security is integrated into the DevOps cycle, not added at the end. Security Command Center, Cloud Security Scanner, and Binary Authorization are some of the tools that help in achieving this.

7. Collaboration and Productivity: Beyond technical tools, GCP integrates with various collaboration tools to enhance team productivity and communication, a core principle in DevOps culture.

GCP DevOps leverages Google Cloud's global infrastructure and scalable services to optimize the development and operations process, aiming for faster iteration, innovation, and deployment, while maintaining reliability and security.
