Scalability and Elasticity - AWS Storage Services Overview

Scalability and Elasticity

Amazon CloudFront is designed to provide seamless scalability and elasticity. You can easily start very small and grow to massive numbers of global connections. With Amazon CloudFront, you don’t need to worry about maintaining expensive web server capacity to meet the demand from potential traffic spikes for your content. The service automatically responds as demand spikes and fluctuates for your content, without any intervention from you.

Amazon CloudFront also uses multiple layers of caching at each edge location and collapses simultaneous requests for the same object before contacting your origin server. These optimizations further reduce the need to scale your origin infrastructure as your website becomes more popular.
