1. explain the client-server architecture and it's application on the Web
2. explain the separation of concerns between client, server, and proxy and it's impact on the Web scalability
3. discuss the scalability of a particular Web service and the Web in general
4. analyze the applicability and performance of different Web protocols
5. analyze the applicability of different architectural styles for Web infrastructure and Web services design
6. apply the REST and RPC-based architectural styles for Web services design
7. compare the applicability of synchronous and asynchronous protocols for Web-based communication
8. apply the microservices architecture for Web services design
9. compare the characteristics of different Web server load balancing algorithms

Lecturer-driven classroom presentations with live demonstrations of how to implement theoretical concepts in software

Design and development of a RESTful Web service. Design and development of a Websocket-based Web service. Students individually implement given assignment in a recommended programming language or tool, and periodically demonstrate the progress to teaching assistants.

1. Introduction; definition of service-oriented computing as a paradigm for software development and software comsumption; examples of dual interface (GUI and API) of popular Web services; brief history of the Web
2. Basics of HTTP protocol; HTTP request and HTTP response; structure of HTTP message: request and status line, headers, body; URL; HTTP client algorithm; implementation of a simple HTTP client
3. REST and RESTful Web services; REST constraints: network, content, and interaction constraints; REST network constraints: client-server architecture, layered system; proxy and gateway
4. REST content constraints: addressability; resource-oriented architecture; resource identifiers; URI, URL, and URN
5. REST content constraints: connectedness; resource representations; hypermedia; hypermedia formats: HTML, XML, JSON; media types in HTTP; content negotiation
6. REST interaction constraints: uniform interface and statelessness; HTTP methods; HTTP status codes; safety and idempotence of HTTP methods; example of server-side software implementation of a RESTful Web service
7. REST interaction constraints: caching and code on demand; conditional HTTP request and its impact on scalability; cache topologies; cache processing algorithm; REST triangle; REST maturity model
8. Midterm exam
9. RESTful API design; resource and URI design; resource modelling; interaction design; metadata design; HTTP persistent connections; HTTP pipelining
10. Asynchronous and real-time Web; server push technologies: polling and long polling; AJAX and Server Sent Events (SSE); Websocket protocol and Websocket API; performance and scalability comparison of polling, long polling, and Websocket based communication
11. Web hosting; dedicated Web hosting; virtual Web hosting
12. Web server load balancing; Quality of service (QoS) in service-oriented systems
13. RPC frameworks; RPC-style Web services
14. Microservices architecture
15. Final exam
