Open Source Load Balance

Research and application of cloud resource management system based on open source platform yuan This paper, based on an enterprise cloud Platform system Project, studies how to realize effective cloud resource management in OpenStack and cloud foundry open source platform, and to develop and realize cloud computing resource management system. The resource management system realizes the real-time monitoring of the virtual machine, the server resource load, records the monitoring data, and on this basis, realizes the flexible and scalable management function of the platform resource automation. Through the analysis of Virtual machine resource use of monitoring records, on the virtual ...

OpenStack Object Storage (Swift) is one of the subprojects of the OpenStack Open source Cloud project, known as Object storage, which provides powerful extensibility, redundancy, and durability. This article will describe swift in terms of architecture, principles, and practices. Swift is not a file system or a real-time data storage system, which is called object storage and is used for long-term storage of permanent types of static data that can be retrieved, adjusted, and updated as necessary. Examples of data types that are best suited for storage are virtual machine mirroring, picture saving ...
