LearnFlex™ HostingOperitel Corporation can provide the hosting and maintenance of the LearnFlex™ application in its secure facility. All Operitel hosted iterations of LearnFlex™ come with a 99.997% uptime guarantee. Operitel clients have their own dedicated primary servers with a shared backup environment. The application is designed to run in a 3-tier environment – allowing for logical and physical division of presentation, business logic and data storage environments. The product architecture is designed as a series of component plug-ins, allowing for clearly defined points of entry and exit for modification purposes. Each tier of the environment is supported by an extensive series of pre-emptive diagnostic tools. These tools are supported through the What’s Up monitoring infrastructure. In addition, the database component maintains full, differential and transaction log backups. Finally, the entire system is replicated daily to a backup environment. Each component of the application is designed to run on the Microsoft 2000 line of products. For the LearnFlex™ hosted solution, Operitel has a clear disaster recovery plan, which includes the following steps:
Backups of the application and application data are made on a daily basis. Transaction log backups are created every 4 hours, while a differential backup is created on a nightly basis. Should an issue occur at a server level, a new server is made available from stock, and the base server configuration installed. At that point, image backups of the original configuration are applied and tested. In the case of a database server, backups are restored and rolled forward to the last available transaction log backup. Full system backups are performed on Sunday evenings. Differential backups are performed Monday through Saturday evenings. Transactional backups are performed every 4 hours. |
