Description
Problem Description
• Create a server program which accepts client requests, process it and responds back to the client. The
complexity of the server program may vary in terms of computation, memory usage, I/O operations, etc.
For example, a server program which takes input as a string from the client and returns the reversed
string.
• Create a client program to vary the rate of the request (requests per second) submitted to the server
program. You can choose any programming language for writing a client-server program such as Node.js,
Python, Java, etc.
Evaluation
• Evaluate the pattern of the client request rate and the server response time without using the auto-scaling
feature.
• Evaluate the behavior of the client-server program with Auto Scaling and load balancing. Test the Auto
Scaling feature with different parameters such as CPU utilization, network I/O, memory usage, number of
requests, etc. Observe the pattern in the client request rate and the response time, identify the parameters
responsible for variation in the response time and provide the reasons for the same.
Submission guidelines
• Submit the source code of client and server program for the assignment. All other supporting files used
for generating plots, logs, etc. should also be placed in the zip file (Roll_number.zip).
• Submit a README file containing the necessary details for running your program on the cloud.
• For different rate of requests (10-1,00,000 request per second), the client program should create a file
rate_n.txt and write the response times for each request in a new line. Here ‘n’ specifies the number
of request per second. The client program should run for at least one minute.
• Create a file Output.txt containing the average response time for each request rate in a new line. Format:
.
• Create separate folders for output files (With/Without Auto Scaling).
• Prepare a report explaining the plots (request vs response rate) and results in detail. Also, Specify the
cloud provider and instance configurations used for the assignment.
Bonus
Compare Auto Scaling feature of AWS and GCP with relevant plots and data using the same client-server
program. You are supposed to bring out the relevant details on the differences you observed running the
program on these cloud platforms.
