APIs

• RESTful APIs are typically used when there's no need for real-time communication, but rather just sending/receiving information periodically.
• WebSockets are used when there needs to be real-time communication between the server and clients, or if data needs to be sent back and forth frequently.
• A RESTful API uses HTTP methods such as GET, POST, PUT, DELETE, etc., while a WebSocket API does not use these methods.
• WebSockets allow for bidirectional communication between the server and clients, making it ideal for applications where data needs to be updated frequently or in real time.
• AWS Lambda allows developers to run code without provisioning or managing servers, which reduces operational overhead and costs associated with running an application on EC2 instances.
• REST APIs allow for one-way requests only, whereby the client makes a request to the API.
• A PUT request overwrites an existing resource or creates a resource with the same name.
• A POST request is a request for a resource that is not currently available.
