| dc.description.abstract | Over the last two decades, the functions of the Internet have rapidly expanded from providing a simple text-only email service to information retrieval, multi-media streaming, on-line advertising, shopping, banking, trading, and many other business tasks. Both businesses and people nowadays have become relying heavily on the Internet for their everyday lives and activities. Today all the services are intended to be 24x7 (24 hours a day, 7 days per week), even those with a short life or small business. In order to fulfill that demand, new server architectures have been developed and more servers are deployed to provide scalable, highly available and reliable services. In this thesis, we propose
a low-cost high-availability solution for business without requiring the use of expensive additional hardware or software. Tools and techniques that we choose
to deploy our system model are also discussed. The solution, which we use to
reduce cost and ensure high availability feature, is “high-availability virtualization
in cluster”. By combining high-availability cluster configuration and virtualization, we save a large of money to buy several physical servers. Concurrently, by using Storage Area Network (SAN) with iSCSI protocol, we do not need to use special hardware and dedicated devices. | en_US |
