The time delta grows significantly as additional and larger objects are requested, which require further TCP ACKs and more round trips. By moving content closer to the client with an edge proxy, if the RTT is 30 ms, the first html file will be received within 120 ms. In the example latency diagram, with 100 ms of latency, it will take at least 400 ms for a client to receive the first html file. Features such as TCP and HTTP fully proxy, SSL termination, caching, compression, and security white/black listing enable better performance for clients and better, distributed security for the applications. The forward proxies have minimal latency between the clients, which significantly accelerates connection establishment and data transfer. Deploy application proxies close to where the clients reside. The applications remain unchanged, residing in the primary data centers. Since the databases that underpin the apps must remain in the primary data centers, options are somewhat limited. The best way to do this is to move the applications closer to the clients. For some applications though, it is imperative to minimize the latency.

Typically applications are hosted in one or two data centers with clients connecting over the Internet to interact with the apps. Provide application proxy services adjacent to clients to improve performance and security.
