Activité Pratique N°3 : Systèmes Distribués avec GRPC

Objective:

• First part : We want to create a client-server application based on GRPC which exposes a service which makes it possible to consultbank accounts.

• Second part : Create a GRPC chat server:

    1. Test the Chat server with a GRPC client like BloomRPC 
    2. Create Java GRPC Client 
    3. Create a Python GRPC Client 
  

• Third part : Create a GRPC GAME server : At startup the server chooses a random number between 1 and 1000 Then the GRPC clients must guess the secret number in competition and the server responds each time with the following eventualities:

    1. Your number is greater
    2. Your number is smaller
    3. BRAVO you won and send the winner to customers
    4. Game over, the winner is ""Winner's number" 
  

===========================================================================

First part:

1 ---> Test the Unary Model using BloomRPC:

---> Test With client using blockingStub (mode synchrone):

2 ---> Test the Streaming Model using BloomRPC(count to 21):

--->The client number 3 got an item every second (Server Streaming) :

3 ---> Streaming request from client and got response based on streamed requests (perform stream):

---> Perform stream:

4 ---> Bi-Directional (fullcurrencystream) send un recive a stream:

=======================================================================

Second part:

1 --> Create a GRPC Chat server and Test the Chat server with a GRPC client like BloomRPC :

Typing user name BloomRPC:

Display who is on chat (Server) :

Sending a message :

Display who sent a message (server) :

display messages BloomRPC :

2 -->Create Java GRPC Client :

Java Client :

Server displaying:

3. Create a Python GRPC Client :

The Server:

java client:

Python Client:

=======================================================================

Third part:

Test with BloomRPC (who wins):
