High availability using virtualization

High availability using virtualization - 3RC

High availability has always been one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This ne...

Leveraging virtualization to optimize high-availability system configurations

Leveraging redundant resources is a common means of addressing availability requirements, but it often implies redundant costs as well. At the same time, virtualization technologies are bursting into data centers with the promise of reducing costs through resource consolidation. Can virtualization and High Availability (HA) technologies be combined to optimize availability while mini...

Availability Analysis and Improvement of Software Rejuvenation Using Virtualization

Availability of business-critical application servers is an issue of paramount importance that has received special attention from the industry and academia. To improve the availability of application servers, we have conducted a study of virtualization technology and software rejuvenation that follows a proactive fault-tolerant approach to counter act the software aging problem. We present Mar...
