Patent ID: 8893129

Claim:
A system, comprising: one or more Central Processing Units (CPUs) configured to execute one or more applications on a host with a host operating system; one or more memory storage locations operatively connected to said one or more CPUs, the one or more memory storage locations configured to store isolated environments containing said one or more applications, wherein the isolated environments comprise at least one of: one or more interception layers configured to intercept access to system resources and interfaces for the one or more applications, one or more barrier synchronization barriers, and a checkpointing library for each of the one or more applications configured to capture a runtime state of the one or more applications; and an interception database configured to map between resources inside and outside the isolated environments for the one or more applications, wherein the one or more applications are isolated from other applications and said host operating system while the one or more applications are running within the isolated environments, and wherein the live migration of the one or more applications is performed by said checkpointing library performing a checkpoint-restore operation; wherein the one or more applications are live migrated between isolated environments running on different hosts; wherein the one or more applications are kept running on a primary host within an isolated environment and live migrated to isolated environments running on one or more additional hosts to perform a scale-out operation between said primary host and the one or more additional hosts.
