In today's public and private cloud markets, availability is a very important metric for all cloud service providers. COLO is an ideal Application-agnostic Solution for Non-stop service in the cloud. Our solution can protect user service even from physical network or power interruption. And the the switching process is difficult for users to perceive (TCP connection will not be terminated). Under COLO mode, both primary VM (PVM) and secondary VM (SVM) are running parallel. The COLO has more than ten times performance increase compared with previous solution (like Remus). Current COLO codes has been merged in QEMU community, we can use COLO in upstream without any other addition patches. In this talk, we will talk about the COLO implementation in QEMU and Xen, the new designed COLO-Proxy, discussing on problems we've met while developing COLO. and report the latest progress from Intel.
