Course Outline
Introduction
- System and service architecture, PaaS, and cloud-native design
Overview of Monolithic System Architecture
- Running an entire monolithic application's functionality within a single process
- Scalability achieved through replication across multiple servers
- Protocols used in monolithic systems: EAI, CORBA, etc.
Overview of Web Services
- Service-Oriented Architecture (SOA) and Microservices Architecture
Service-Oriented Architecture (SOA)
- Benefits and costs of SOA
- Successes and failures in implementing SOA
- Messaging and ESB
- Infrastructure and tools supporting SOA
How Microservices Implement Web Service Concepts
- Focus on doing one thing and doing it well
- DevOps
- Continuous Deployment and Delivery (Continuous Integration, Continuous Build Process, etc.)
- Lightweight protocols
Microservice Protocols and Standards
- HTTP, JMS, AMQP, WebSockets, JSON, etc.
Development Frameworks for Building Microservices
- Java-based frameworks (Spring Cloud)
- JavaScript-based frameworks (Seneca)
Decomposing a Monolithic Application
- Developing independently deployable applications
- Organising microservice applications around business capabilities
- Case study: Migrating a monolithic application to three core microservices
