What is a stateless Microservice?
Stateless microservices do not maintain any state within the services across calls.
They take in a request, process it, and send a response back without persisting any state information.
Rather than store this state internally, a microservice should store state information externally, in some type of data store..
Is SMTP stateful or stateless?
Note that SMTP is a stateless protocol as the mail server does not maintain any connection with the client, it does not store any information about the client. If an email is asked to be sent twice, the server will resend it without saying that the email has been sent. POP3 is also a stateless protocol.
Is HTTP 1.1 stateless?
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.
What is state and stateless?
Stateless Protocol is a network protocol in which Client send request to the server and server response back as per the given state. Stateful Protocol is a network protocol in which if client send a request to the server then it expects some kind of response, in case of no response then it resend the request.
Is UDP stateless?
Stands for “User Datagram Protocol.” It is part of the TCP/IP suite of protocols used for data transferring. UDP is a known as a “stateless” protocol, meaning it doesn’t acknowledge that the packets being sent have been received.
What happens if a person is stateless?
What Are the Consequences That Stateless People Encounter? Without citizenship, stateless people have no legal protection and no right to vote, and they often lack access to education, employment, health care, registration of birth, marriage or death, and property rights.
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.
Is DNS stateful or stateless?
1 Answer. The DNS protocol is stateless, in that it determines that right now this name resolves to this IP address, and doesn’t make assumptions about how long this will be. The DNS infrastructure is not something you could define as a state machine.
Is SMTP connectionless?
SMTP operates over the connectionless User Datagram Protocol (UDP) and supports text-oriented e-mail between any two devices that support Message Handling Service (MHS).
Is TCP stateless?
The TCP protocol is a stateful protocol because of what it is, not because it is used over IP or because HTTP is built on top of it. … This state (how much bytes the other guy can receive, and whether or not he did receive the last packet) allows TCP to be reliable even over inherently non-reliable protocols.
Is FTP stateful or stateless?
Unlike HTTP, the FTP protocol is stateful: the client establishes a Control Connection for the duration of an FTP session that typically spans multiple data transfers. FTP uses a separate TCP connection for data transfer.
What does UDP stand for?
User Datagram ProtocolThe User Datagram Protocol (UDP) is a lightweight data transport protocol that works on top of IP.
What is stateless architecture?
Stateless Architecture means the app is dependent only on Third-party storage because it doesn’t store any kind of state in memory or on its disk. All data it needs or requires has to fetch from some other stateful service (Database) or are present in the CRUD request. … Stateless applications scale very poorly.
Why is HTTP stateless?
HTTP is called as a stateless protocol because each request is executed independently, without any knowledge of the requests that were executed before it, which means once the transaction ends the connection between the browser and the server is also lost.
Is stateless better than stateful?
Stateless and stateful container management Stateless is the way to go if you just need information in a transitory manner, quickly and temporarily. If your app requires more memory of what happens from one session to the next, however, stateful might be the way to go.
Is SMTP synchronous or asynchronous?
So yes it’s synchronous. Well, the “send” to the smtp server is synchronous, but if you were trying to make sure the message got to its intended destination, you’re out of luck. SmtpClient will wash its hands of the operation as soon as the Smtp server acknowledges receipt.
