Performance efficiency is the backbone of system stability. As part of my IS 215 research, I conducted a performance assessment comparing a single-core (t2.micro) instance against a multi-core (t2.medium) instance. 

Using the stress tool and real-time monitoring, I observed several key differences: 

  • Utilization Efficiency: Under identical workloads, the single-core instance reached 11.2% utilization, while the multi-core instance only reached 6.0%, effectively halving the strain by distributing tasks.
  • Load Average Scalability: The single-core system experienced significantly higher "pressure," with a maximum load of 0.16 compared to the multi-core’s 0.08.
  • System Recovery: Multi-core systems demonstrated a superior ability to clear process queues, returning to an idle state immediately after stress, whereas the single-core system lagged behind.

This data confirms that while single-core systems handle tasks sequentially, parallel processing in multi-core architectures is vital for maintaining responsiveness during high-demand spikes.

In this activity, I successfully deployed a networked content management system (CMS) using Amazon EC2 and Nginx. This process involved several critical layers of cloud architecture:

  • Virtualization: Launching an Ubuntu 24.04 instance on AWS to serve as the remote host. 
  • Static Networking: Allocating and associating an Elastic IP address to ensure the server maintains a persistent identity on the public internet, even after reboots.
  • Web Server Configuration: Configuring Nginx and PHP 8.5-FPM to run under the 'ubuntu' user for streamlined permission management.
  • DNS Integration: Pointing a custom subdomain (la2.bsabanilla.is215.upou.io) to the cloud instance to make the site accessible via a human-readable URL.

By integrating these components, I transformed a raw Linux environment into a functional, networked web application ready for global traffic.
