Overview
The goal
A resilient infrastructure is key
Today's business environment is characterised by rapid, unpredictable changes - some of which present opportunities, others that introduce challenges and some time even threats. Irrespective of circumstances, it's imperative that businesses be responsive and resilient - seamlessly taking advantage of opportunities while mitigating risks. As such, an IT infrastructure must be designed to help insure the continuity of business operations in the event of an unexpected disruption and secure data integrity. The infrastructure must rapidly and automatically scale to address marketplace changes.
The advantage
An available, resilient infrastructure
Virtualisation offers a strategy that transcends physical boundaries to improve service delivery, drive down infrastructure costs and help manage risk. Applications are only available if the underlying infrastructure is available and virtualisation can keep applications running through server, storage and application server failures. Consolidating onto virtualised servers means less physical machines to restore. And virtual machine configurations stored in networked files can be restored quickly to another site in the case of a disaster as part of your business resilience plan. Storage virtualisation allows you to restore to different device types without having to have a mirror image of all storage at a disaster recovery site.
The benefits
Superior availability, less complexity and significant cost savings
Virtualisation can lower the cost and complexity of data center sites by allowing flexible and dynamic delivery of shared IT resources as services. Using virtualisation technologies for server and storage systems offers many benefits such as:
- Ability to recover dissimilar hardware offers independence and ability to mix and match technologies
- Faster recovery and ability to meet lower Recovery Time Objectives (RTO)
- Reduced planning time and complexity of test exercises
- Repeatable recovery process
- Easier provisioning of servers and resources
- Significant cost reduction
- Reduced staffing for testing
