No, RESTful API and web services are not the same thing, although they are related. Web services are a broader concept that refers to any service that is made available over the internet, using protocols like HTTP, SOAP, or XML-RPC. Web services can be implemented using various architectures and technologies. RESTful API (Representational State of Resource), on the other hand, is a specific architectural style for designing networked applications. It is a subset of web services that adheres to specific principles and constraints, such as: - Resource-based - Client-server - Stateless - Cacheable - Uniform interface - Layered system In other words, all RESTful APIs are web services, but not all web services are RESTful APIs. RESTful API is a specific approach to building web services that follows specific guidelines and principles. Here's an analogy to help illustrate the difference: - Web services are like restaurants that serve food (data). - RESTful API is like a specific type of restaurant (e.g., Italian) that serves food (data) in a specific way (following specific principles and constraints). read less

Facebook uses Amazon Web Services (AWS) for hosting its applications, but it doesn't use it as its primary backend infrastructure ¹. Instead, Facebook uses a combination of its own infrastructure and AWS for specific services. For instance, Facebook uses AWS for its developer platform, allowing developers to create and deploy apps on AWS infrastructure ¹. Additionally, Facebook uses AWS for specific services like Amazon Lex for chatbots and Amazon AppFlow for data transfer ² ³. However, the core Facebook backend infrastructure is built and managed by Facebook itself. read less

RESTful APIs, allowing developers to define the endpoints, request and response formats, authentication methods, and other relevant information in a machine-readable format. This facilitates easier integration, documentation, and testing of APIs. Other frameworks and specifications, such as RAML and API Blueprint, also exist for defining RESTful services, but OpenAPI is the most widely adopted standard.
