Clustered Redundant Failover Systems
July 7, 2008
Clustered Caching Environment – This engine allows caching of both static and dynamic content. When security permits, authenticated and personalized content can also be cached. This architecture allows us to provide extremely fast site response and support more site visitors – and traffic spikes – than a standalone application server environment.
Clustered Application Server Farm – This approach provides more reliable content delivery and higher user satisfaction than typical hosting solutions. ePublishing’s redundant servers are isolated from the heavy loads of page servers by our caching network, allowing our servers to function on reduced system loads to operate faster and more accurately.
Clustered Backend Database Servers – ePublishing hosting relies on a redundant cluster of MySQL database servers. This allows us to cache frequently used queries, intelligently load-balance requests to multiple servers, and automatically monitor and respond to system load. This approach ensures lightning-fast response and the maximum reliability of your databases.
Clustered Mail Environment – Our clustered mail services maintain reliability when you are sending email and receiving feedback from your client base.
Redundant DNS Environment – Our domain name services environment provides multiple servers residing on separate networks, enabling highly available and fast DNS lookup.
Redundant Storage Solution – ePublishing has adopted industry-leading Network Appliance (NetApp) Filer storage equipment to ensure that your content remains highly available and is in continuous sync between our Virginia and Chicago data centers.
Redundant System Back Up and Hot Deploy – This backup system allows us to restore a single file, a directory or an entire drive, with full backups of client data, images and software from the previous year.
Clustered Video & CDN – Video hardware is optimized to serve through our CDN, with failover and scalability.
Security By Design – Multiple pairs of firewalls running in high availability are tightly restricted while application servers are physically segmented from database servers.
Administrator access is controlled via a separate VPN and backend network.
Administration, Development & Staging Environments -ePublishing uses a dedicated back-end network for administration, leaving the front-end network fully available for customer traffic and keeping sensitive data on the closed back-end network.
Our sophisticated development platform separates the clusters into development, quality assurance, staging and production environments. This allows the development of the features you request while you review and test new features without affecting your production site. New features are added to your site after you have approved their functionality, not before.
