US Patent 9794275 Lightweight replicas for securing cloud-based services

Methods, computer program products, computer systems, and the like, which provide security in cloud-based services using lightweight replicas, are disclosed. The methods, computer program products, computer systems, and the like include detecting an intrusion into an application server, dynamically provisioning a replica application server in a server system in response to the detecting the intrusion, and transitioning a datastream from the application server to the replica application server, where the application server is provisioned in the server system, the intrusion is an attack on the application server, and the attack is conducted via a datastream between a first computing system and the application server. The replica application server is a replica of at least a portion of the application server.
