- Enterprise Performance. High-availability products for Enterprise Hosting customers who have
a Web site consisting of multiple servers that require high performance and availability.
Enterprise Performance and Enterprise Managed Applications product lines offer performance and
commerce functionality to enhance Enterprise Hosting solutions.
Enterprise Performance is a suite of performance enhancements designed to ensure server
availability (minimum downtime) and server response (minimum delay). Services such as Load
Balancing, Site Accelerator, Site Replication, and Traffic Distribution are available under this
offering. In addition, more demanding service level agreements are offered under these services:
- Load Balancing. This service is for businesses with high-traffic Web sites that require
scalability and additional system performance, while minimizing downtime for missioncritical
applications. This service balances the traffic load between web servers in the same
data center. It automatically routes traffic to other servers if one is down.
Load Balancing balances network load by directing network connections to the server with
the least number of open connections. It attempts to maintain an equal number of
simultaneous sessions on all servers (assuming all servers have the same capacity). A
different algorithm is used for servers with large differences in capacity.
- Site Accelerator-Web Caching. Caching is based on the idea that some web site content is
requested frequently, while other content is seldom requested at all. It places frequently used
content closer to end users by geographically distributed caching servers. A web cache is a
computer system that monitors web object requests, and stores objects it retrieves from a
server. On subsequent requests for the same object, the cache delivers the object from its
storage, rather than passing the request on to the origin server. This approach accelerates web
page downloads, reduces the number of requests to the origin server, making it more
responsive and reducing bandwidth as much as 35 percent. Without caching, all traffic must
travel to the origin server every time a page is requested, resulting in potentially long delays
and user frustration.
Since every web object changes over time, caches also determine whether or not their copy of
an object is still "fresh" or whether they need to retrieve a new copy from the origin server.
Web caching is particularly suited for static content, such as logos and other images and html.
- Traffic Distribution/ Hopscotch. Designed for customers with high-traffic Web sites that are
hosted at multiple data centers. Geographically distributed mirrored web servers provide the
best end-to-end response and site redundancy. Enterprise Performance products offer a tiered
approach to distributed hosting, starting out with local load balancing, moving up to caching,
and finally to geographically distributed servers in multiple data centers.
- Site Replication. Designed for businesses who need high availability of Web hosting, without
the overhead associated with replicating files, and to ensure that content on all servers is
synchronized. Distribution hosting in the same or different data centers requires the server
content to be mirrored. Site Replicator is a tool for making sure that the content across all
servers is the same, and that the data are synchronized. Site Replicator provides automatic
content update and replication between a master Web server and multiple slave Web servers.
It updates content on a scheduled, periodic, or on-demand basis.
- Enterprise Commerce. A combination of pre-configured and custom applications for Enterprise
Hosting customers covering a wide range of E-business solutions.
