Coding Towards The Answer, Part 8

Let’s simulate computational nodes doing load balancing act.

import random
import matplotlib.pyplot as plt

# Constants
NUM_SERVERS = 7
NUM_REQUESTS = 10 # sessions
MAX_REQUESTS = 10

# Server class
class Server:
    def __init__(self):
        self.load = 0

    def process_request(self):
        self.load += 1

    def get_load(self):
        return self.load

# Initialize servers
servers = [Server() for _ in range(NUM_SERVERS)]

# Process requests
for _ in range(NUM_REQUESTS):
    # Select server
    # server = random.choice(servers)
    # Generate a random number of requests for this iteration
    num_requests = random.randint(1, MAX_REQUESTS)

    # Process each request
    for _ in range(num_requests):
        # Select server with the minimal load
        server = min(servers, key=lambda s: s.get_load())

        # Process the request on the selected server
        server.process_request()

# Get server loads
loads = [server.get_load() for server in servers]

# Plot graph
plt.bar(range(NUM_SERVERS), loads)
plt.xlabel('Server')
plt.ylabel('Load')
plt.title('Load…
