Eight Components of Whole-Site Acceleration
Eight components of whole-site acceleration
Whole-site acceleration is a completely integrated system that optimizes and accelerates all content and applications delivered by an origin server to an end customer. Whole-site acceleration puts an end to segregation of content by type since it serves as a proxy for all of the content provider's Web traffic. True whole-site acceleration should comprise all of the following eight components:
Component No. 1: Acceleration of static content
Static content objects that do not change for the user (such as graphics, videos and browser-based Flash applications) are cached at distributed locations for faster delivery.
Component No. 2: Acceleration of dynamic content
DSA speeds delivery of dynamic Websites and Web applications for an enhanced user experience. Acceleration of dynamic content is particularly important for e-commerce, news feeds, PHP, JavaServer Pages (JSP) and machine-to-machine traffic. This acceleration is accomplished through protocol and connection optimization between the origin server and the CDN, plus a reduction in origin server load for much higher efficiency. DSA will typically decrease latency for first byte delivery and the time to deliver an entire object. DSA also reduces the amount of round trips needed from the user to the origin per object.
Component No. 3: Flexibility of dynamic acceleration mode
Whole-site acceleration offers the flexibility to utilize asymmetric, symmetric or mixed-mode acceleration of dynamic content. With asymmetric acceleration, connection aggregation and protocol optimization occur between the content provider's origin server and a last-mile POP that is close to the user. Symmetric acceleration provides an additional acceleration touch point near the content provider's origin server, enabling faster acceleration and superior congestion control management. The flexibility of choosing acceleration modes enables online businesses to evaluate the costs and benefits of each mode for a given location and service.
