Is Facebook stateful or stateless?

Facebook continually uses a stateless service. When the server requests a list of recent messages using the Facebook API, it issues a GET request with token and date. The response is independent of any server state, and everything is stored on the client’s machine in the form of a cache.

What is meant by stateless protocol?

HTTP is a stateless protocol. This means a HTTP server needs not keep track of any state information. So, At any time, client can send any valid command. The server will not relate this command to any previous or future commands.

Why Microservices are stateless?

Like other distributed computing architectures, microservices scale better when they are stateless. Within seconds, multiple containers can be launched across multiple hosts. Each container running the service is autonomous and doesn’t acknowledge the presence of other services.

Why FTP is not secure?

FTP was not built to be secure. It is generally considered to be an insecure protocol because it relies on clear-text usernames and passwords for authentication and does not use encryption. Data sent via FTP is vulnerable to sniffing, spoofing, and brute force attacks, among other basic attack methods.

Why is REST API called stateless?

As per the REST architecture, a RESTful Web Service should not keep a client state on the server. This restriction is called Statelessness. It is the responsibility of the client to pass its context to the server and then the server can store this context to process the client’s further request.

Why HTTP is called stateless protocol?

FTP uses a separate TCP connection for data transfer. … Historically, the data connection was established from the server back to the client.

What is the advantage of stateless protocol?

The following are some advantages of statelessness: As the server does not need to manage any session, deploying the services to any number of servers is possible, and so scalability will never be a problem. No states equals less complexity; no session (state) synchronize logic to handle at the server side.

What is the problem with statelessness?

Inheriting a nationality can also be problematic and in cases where a father is stateless or has divorced, the mother is often unable to pass her nationality on to children even though they are born in her own country. Failure or refusal to register a child’s birth can result in statelessness.
