Server Clustering in Cloud Computing Using Proxmox Based High Availability Method

Cloud Computing technology Service and data stored on machine, the server this makes important factor engine server as a supporting service availability. More and more users are accessing the service will result in engine performance server load becomes heavier and less than optimal, because the service must work continuously to provide data that can be accessed anytime by the user via the network connected. Server hardware has a performance period. Likewise with software that may crash. With functionality server which provides services to the client, the server is required to have level of availability. A high this enables the engine server to experience downtime. Server machine must also be turned off for maintenance purposes. The purpose of this study is build Clustering Server to work together as a single system which over the virtual environment. This is a solution to overcome these problems. In this study researcher use a server virtualization proxmox, FreeNAS is a NAS server and DRBD to support high availability of services in the sphere of HA, data synchronization in a High Availability to perform mirroring another system machine. With the implementation of the method of HA and synchronization DRBD and NFS (Network File System) on a system cluster obtained results average migration time on node1 towards node2 reach 9.7(s), 3.7(s) for node2 towards node3, and 3(s) on node3 towards node1. Also obtained downtime less amounting 0.58 ms on node1, on node2 0.02 ms, and 0.02 ms on node3.
