This is accomplished by having Citrix Netscalers as the front end into the data centers as the starting point. Netscalers handle everything from Load Balancing, DDoS protection and data compression to ensure that our sites run at peak performance. Netscalers are superior in terms of security, speed and reliability to anything on the market, so much so that Google uses thousands of them for their infrastructure.

We also have layer 2 fiber networks between the data centers so as far as the servers know, they are sitting right next to one another in a rack. This allows us to load balance between our servers in a very efficient way. We can restart a server for maintenance reasons and because of this and our redundancies, the website will never go down for the end user.

Our databases, in addition to being clustered within a data center, also use log shipping to back up to a database in the alternate datacenter to ensure uptime in the case of an entire data center going down.

We employee multiple CDN networks to ensure that your image and download objects reach the end users with maximum efficiency and reliability. We also have many servers from which the CDN networks read to ensure that the CDN can always access the files.

Our data centers are co-located with major co-location providers that ensure the highest levels of physical security to our equipment.

Security: We go to the effort of making sure that we use only the JBoss modules that are needed so as to minimize security risks as much as possible. In addition, we are battle hardened in the security arena. Some of the sites that we host have been the target of many attacks over the years and we have weathered them and built up security to ensure that the attackers do not gain the upper hand. We also do not use any offshore outsourcing so we can keep very tight control of our code base. We double encrypt all sensitive data in our database, using the highest encryption available, so even if someone were to retrieve it, they would not be able to read it.

Scalability: Our code is designed to be linearly scalable. If we need to increase capacity, we just add commodity application servers. We have our own tested memory caching systems, in addition to using third party ones and have many other proprietary systems to ensure that whatever level of traffic you want to send to a site, we can handle it.

Speed: Our entire code base and backend infrastructure is designed to be the most efficient possible. In all Keynote and other performance metrics, our code execution time is well below some of the fastest sites on the internet. We regularly see our web pages returning in sub-second response times.

Proven: Our code base and system was built from the ground up, having spent millions of dollars, to be an enterprise level system that could grow and expand to accommodate whatever could be thrown at it. It has spent the last 8 years proving that to be true.
