"You build it, you run it (the person who builds the code needs to be responsible for making the code run in the production environment, and is responsible for the subsequent maintenance work)"
"You build it, you run it" is a concept of software development and operation and maintenance, emphasizing that the development team needs to take complete responsibility for the code it builds, including deploying the code to the production environment and performing subsequent maintenance and operation Work. There are several important ideas behind this idea:
- Responsibility: Developers need to take responsibility for the code they build and realize that they don't just write the code, they also need to ensure that the code will run successfully in a real production environment.
- Agility and fast feedback: Since the development team is responsible for running the code, they can find and resolve runtime problems more quickly. This reduces troubleshooting and repair time, thereby ensuring system agility and stability.
- Continuous delivery and automation: By building automated release processes and deployment tools, teams can more easily deploy code into production and reduce human error. This improves the speed and quality of delivery.
- Knowledge transfer and skills expansion: "You build it, you run it" encourages developers to gain a comprehensive understanding of the entire life cycle of software, including operational knowledge and skills. This facilitates knowledge sharing and team collaboration, and equips developers with a wider range of skills, increasing overall team efficiency and flexibility.
Platform engineering
In the cloud-native era, platform engineering involves building and operating a cloud-native platform to support an enterprise's applications and services. The cloud-native platform aims to provide highly scalable and elastic infrastructure and tools based on cloud computing and containerization technologies, as well as the concept of microservice architecture and continuous delivery, to support the development, deployment, operation and management of applications.
Platform engineering tasks include:
- Build and manage cloud infrastructure: Platform engineers are responsible for designing and deploying cloud infrastructure, including computing resources, storage, and networking. They need to choose the right cloud platform, configure and optimize the infrastructure to ensure high availability, resiliency and security.
- Containerization and orchestration: Platform engineers use container technologies (such as Docker) to package applications into portable containers, and use container orchestration tools (such as Kubernetes) for automated deployment, management, and scaling. They need to define and maintain container images, set container orchestration policies, and ensure high availability and load balancing of applications.
- Automation and Continuous Delivery: Platform engineers focus on building automation tools and processes to enable continuous integration, continuous delivery and continuous deployment (CI/CD). They need to configure and manage build tools, source control systems, and automated testing frameworks so development teams can deliver new software releases quickly and reliably.
- Monitoring and Troubleshooting: Platform engineers need to build monitoring systems to monitor application and infrastructure performance and availability in real time. They need to configure and manage log management tools, monitoring tools and alarm systems, as well as define early warning and automated failure recovery strategies.
- Security and Compliance: Platform engineers need to ensure the security and compliance of cloud-native platforms. They need to implement authentication, access control and data encryption policies, conduct regular vulnerability scans and security audits, and comply with relevant industry and legal regulations.
Containers and Containers and WebAssembly (WASM)
Containers and WebAssembly (WASM) have played an important role in platform engineering, mainly including the following functions and roles:
- Isolation and Security: Container technologies such as Docker provide a lightweight way to isolate an application and its dependencies into self-contained containers. This enables applications to be deployed and run in a unified operating environment while isolating resources and dependencies between different applications. WASM, as a compiled bytecode format, provides a secure execution environment that can run in isolated containers while limiting access to underlying system resources.
- Portability: Containers and WASM can run across platforms and are not limited by specific operating systems or hardware architectures. Containers can run on multiple operating systems and cloud platforms, while WASM can be executed in different runtime environments, such as browsers, servers, etc. This portability allows developers more flexibility in deploying and migrating applications.
- Scalability and Elasticity: Container technology provides a lightweight approach to virtualization that enables applications to quickly scale up or down when needed. Containers can automatically adjust the allocation of resources according to load conditions to provide better performance and reliability. WASM can achieve high-performance compilation and execution. When running in a container, it can quickly respond to requests and handle a large number of concurrent tasks.
- Ecosystem Support: Both containers and WASM have a large ecosystem and community support. The container ecosystem provides a rich set of tools and services for building, testing, deploying, and managing containerized applications. The WASM community provides a series of toolchains, libraries, and frameworks for developing and executing WASM modules. With the support of these ecosystems, platform engineers can develop and manage applications more efficiently.
