Study Notes
API Definitions and Specifications
- API definitions follow standardized specifications like OpenAPI and AsyncAPI.
- These specifications provide a common format and vocabulary for API definitions, establishing foundations for documentation, contracts, mocks, and tests.
Stage 3: Develop
- Developers write code based on API designs to implement functionality.
- Version control is often managed through Git, allowing teams to manage changes and revert as needed.
- Many teams utilize GitHub or GitLab repositories for source code, issue tracking, and code reviews.
- Clear definitions of development workflows are crucial for standardizing team approaches.
Stage 4: Test
- API testing takes place during developing, securing, and deploying phases of the API lifecycle.
- Testing can be conducted manually or automatically from various locations or within CI/CD pipelines.
- Early and frequent testing helps identify and resolve issues before production.
- Types of API tests include:
- Contract Tests: Ensure API changes comply with original design promises.
- Performance Tests: Confirm response times meet expected standards.
Stage 5: Secure
- The security phase involves checking APIs for vulnerabilities that could compromise overall application security.
- Authentication logic must validate users to prevent unauthorized access.
- Security checks can be performed manually or automatically within CI/CD workflows.
Stage 6: Deploy
- Deployment involves publishing APIs to development, staging, and production environments.
- CI/CD pipelines and API gateways are often used to standardize the deployment process.
- Predictable deployment processes benefit agile teams that release code multiple times a week.
Stage 7: Observe
- Observability includes collecting, visualizing, and alerting on API telemetry data in production.
- Site Reliability Engineers (SREs) and DevOps teams use monitoring tools to detect performance and security issues.
- API observability helps identify errors, latency, and vulnerabilities before affecting services or customers.
Stage 8: Distribute
- Focus on improving API discoverability through catalogs.
- Public API catalogs facilitate outreach and support for third-party consumers, while private ones aid internal collaboration.
- Detailed descriptions and relevant tags are essential for effective catalog searchability.
System Integration
- Involves creating complex information systems encompassing architecture design, application building, and hardware integration.
- Architecture is defined as the organization of system components, their interactions, and design principles, including future evolution.
Application Program Interfaces
- APIs utilize JSON or XML for data transmission.
- JSON: A text-based format for structured data based on JavaScript syntax, commonly used in web applications.
- XML: Allows for defining and sharing data, supporting information exchange across systems like websites and databases.
API-First Development
- An API-first approach prioritizes APIs at the start of the development process.
- Organizations develop APIs before other code, preventing them from being afterthoughts.
- Understanding the API lifecycle and associated tooling is essential for adopting an API-first model.
