CloudRecovery with Failover
Convergia’s Disaster Recovery and Business Continuity product, CloudRecovery with Failover, gives customers the tools needed to make sure their mission critical applications are available during any type of crisis, whether occurring on site at the customer’s premises or from a natural disaster that impacts a community, city, state, or larger regional area. Business server infrastructure can range from a single server environment to businesses with dozens or hundreds of servers. CloudRecovery focuses on the key servers housing the applications that a business cannot survive without. When initiated, CloudRecovery brings a business back up to production mode in Convergia’s Cloud in a matter of minutes or hours, rather than traditional backup and recovery services that can take hours, days or even weeks.
How CloudRecovery with Failover works
Convergia provisions virtual servers in the cloud for each of the customer’s critical applications. These servers are provisioned in a shadow or hot standby mode with minimal CPU (Computer Processing Units) or Cores and minimal RAM (Random Access Memory) resources in order to keep down costs. With software provided either through Convergia or by the customer, the primary servers at the customer’s site are set to replicate data to the shadow server(s) at a rate determined by the customer to be within the guidance of the customer’s Recovery Point Objective (RPO) (as designated in the customer’s Disaster Recovery and Business Continuity plan). The rate at which data can replicate is limited to the amount of bandwidth the customer has designated to this operation. Most customers use a low percentage of their bandwidth during their business hours for replication and then utilize a higher percentage of the bandwidth on off or slow hours to catch up with their data replication. This occurs most often in the evenings and over the weekends. There are businesses where the RPO is extremely high, meaning the business requires that very little data will be lost in the event of an outage and they require real time replication. In such cases, the customer will designate separate bandwidth resources to provide full time data replications thus not impacting their normal need for bandwidth for other business operations. As the data passes through the shadow server(s), it is stored in Convergia’s SAN environment. All of the customer’s data resides within the Convergia Cloud, accessible by the shadow servers in the event of a major failure or disaster.
After the decision has been made to failover to Convergia’s CloudRecovery service, either the customer’s IT team or Convergia’s support team will log into the Control Panel and assign additional computing resources (CPUs and RAM) to the shadow server(s) and move them into production mode. This process takes an average of four to fifteen minutes. The next step is to re-point end users to the Cloud by re-pointing the external DNS to Convergia. End users are then able to initiate connections and authenticate using their credentials to the virtual server(s) where they can log back into the system and resume work. End user performance is always predicated on the bandwidth connectivity at the remote sites — satellite offices or employee homes. But once connectivity is established the ability to function is restored.
