1. Environment Replication: Create consistent development, testing, and production environments.
2. Microservices: Deploy and manage microservices efficiently.
3. Continuous Integration/Continuous Deployment (CI/CD): Automate deployment pipelines using containerization.

Alternatives:

• Kubernetes (for orchestration)
• Podman
• LXC/LXD

7. GraphQL

GraphQL is a query language for your API, offering a more efficient and powerful alternative to REST. It allows clients to request exactly what they need, reducing over-fetching and under-fetching of data. This flexibility makes GraphQL ideal for complex applications where the front-end requirements can change frequently.

Use Cases:

1. Efficient Data Fetching: Request exactly the data needed, reducing over-fetching and under-fetching.
2. Schema Stitching: Combine multiple GraphQL schemas into a single schema.
3. Real-time Data: Use subscriptions to handle real-time updates.

Alternatives:

• REST APIs
• Falcor
• OData

8. Jenkins

Jenkins is a continuous integration and continuous delivery (CI/CD) server that automates the parts of software development related to building, testing, and deploying. With a vast array of plugins, Jenkins can integrate with almost any tool, making it a linchpin in the DevOps pipeline.

Use Cases:

1. Automated Builds: Compile and build applications automatically after code changes.
2. Testing: Run automated tests to catch bugs early in the development cycle.
3. Deployment: Deploy applications to various environments automatically.

Alternatives:

• GitLab CI/CD
