SOA - Principles (Contract, Composability, Loosely Coupled, Abstraction)

Service-Oriented Architecture (SOA) principles, including Contract, Composability, Loosely Coupled, and Abstraction, are fundamental in designing and implementing successful web services. Contracts ensure clear communication and understanding between service providers and consumers. Composability allows for the creation of complex systems by combining smaller, reusable services. Loosely Coupled services promote flexibility and scalability, enabling changes to be made without impacting other services. Abstraction hides the complexity of services, making them easier to use and understand. These principles are crucial in creating robust and efficient web services that can adapt to changing business requirements.


HTTP - Request Lifecycle

The HTTP Request Lifecycle skill covered in Web Services is crucial for understanding how a web server handles incoming requests from clients. This skill outlines the various stages of processing a request, including receiving the request, parsing the request headers, routing the request to the appropriate handler, executing the handler code, and sending a response back to the client. By understanding this lifecycle, developers can optimize their server-side code, troubleshoot issues, and ensure that requests are handled efficiently and securely. This knowledge is essential for building scalable and reliable web applications.


HTTP - Verbs, Methods

HTTP - Verbs, Methods refers to the actions that can be performed on a web server using the HTTP protocol. The most common HTTP methods are GET, POST, PUT, DELETE, and PATCH. Each method serves a specific purpose, such as retrieving data with GET, submitting data with POST, updating data with PUT or PATCH, and deleting data with DELETE. Understanding and correctly using these methods is crucial in web services development to ensure proper communication between clients and servers, and to perform various operations efficiently and securely.



HTTP - CORS (Cross-Origin Resource Sharing) is a crucial skill in Web Services as it allows for secure communication between different origins or domains. By implementing CORS, web servers can specify which domains are allowed to access their resources, thus preventing unauthorized access and potential security threats. This skill is important for maintaining the integrity and security of web applications and ensuring that data is shared only with trusted sources. Understanding and implementing CORS effectively can help developers create more secure and reliable web services.
