Intelligent and automatic replication load score based load balancing and resiliency of replication appliances

A system comprising:

• a microprocessor;
• and
• a non-transient computer-readable storage medium, comprising computer instructions executable by the microprocessor, wherein the computer instructions are configured to perform a method comprising the steps of:
• receiving replication data, wherein
• the replication data is received at a recovery site from a replication process initiated on a primary site, and
• the recovery site comprises at least a first gateway appliance and a second gateway appliance;
• evaluating a replication load for the first gateway appliance, wherein
• the evaluating the replication load comprises analyzing at least a first evaluation factor for the first gateway appliance and a second evaluation factor for the first gateway appliance, and
• the first evaluation factor for the first gateway appliance and the second evaluation factor for the first gateway appliance are both related to the replication load of the replication process on the first gateway appliance, wherein
• a first weight is applied to the first evaluation factor of the first gateway appliance, and
• a second weight is applied to the second evaluation factor of the first gateway appliance, wherein the first weight of the first evaluation factor of the first gateway appliance is greater than the second weight of the second evaluation factor of the gateway appliance;
• evaluating a replication load for the second gateway appliance, wherein
• the evaluating the replication load comprises analyzing at least a first evaluation factor for the second getaway appliance and a second evaluation factor for the second gateway appliance, and
• the first evaluation factor for the second gateway appliance and the second evaluation factor for the second gateway appliance are both related to the replication load of the replication process on the second gateway appliance;
• determining whether the first gateway appliance is overloaded based on the replication load of the replication process on the first gateway appliance;
• and
• in response to determining that the first gateway appliance is overloaded, rebalancing a replication workload between the first gateway appliance and the second gateway appliance based on the replication load on the first gateway appliance and the replication load on the second gateway appliance.
