Increased Scalability and Flexibility
Important advantages of IaaS involve scalability and flexibility, when your business opens a new offce location, you do not need to spend the money and time to purchase and initiate new hardware to support that offce; instead, you can virtually connect to your infrastructure. IaaS gives any growing business the flexibility it needs from its IT infrastructure.
Iaas allows for quick and easy allocation of resources in a monitored environment where overloading is never a concern as long as the system is managed properly.
To determine a right-sized solution, ongoing performance testing is essential. IT administrators must continually measure factors such as response time, number of requests, CPU load, and memory usage.
Automation can also help optimize cloud scalability. You can determine thresholds for usage that trigger automatic scaling so that there’s no effect on performance.
