Identification of bottlenecks in the system and optimization proposals

Conduct a detailed analysis of the current architecture, identify potential problem areas, and formulate options for their resolution.

The diagram shows a system consisting of:

• PIM — an external source that sends data to the backend (one request every 5 seconds).
• BACKEND — processes incoming requests and sends results to the client side. NGINX is used as the web server.
• FRONTEND — displays the received data (updates occur once per second).

Consider the following:

• The API between PIM and BACKEND is single-threaded.
• There is a difference in the frequency of data transmission from PIM and their display in the FRONTEND.
• Possible issues with performance or data loss.
• Approaches to scaling and implementing asynchronous processing.
