Server virtualisation is one of the real game-changers in the IT domain, not only for the data centres and hosted services but also for administrators who manage them.
Whether you’re new to virtualisation technology or familiar with it by using it every day, you should know the real benefits of virtualisation technology, not only for you but for your business, where every benefit allows you to make your business more efficient, more agile whilst reducing CapEx and OpEx.
The following are some real benefits of virtualisation that make your life much easier whilst improving the performance of your business.
1) Zero Downtime
Moving running VMs from one host to another with zero downtime is one of the more powerful features of virtualisation. This can be achieved by configuring and enabling VMware vMotion, Distributed Resource Scheduler (DRS), High Availability (HA), and Distributed Power Management (DPM) feature.
2) Server Consolidation
Most of the systems are based on x86 architecture that was initially designed for a single OS and single application, and the whole system hardly consumes the 10~15% of the physical resources. With the introduction of hypervisor by VMware, it changed the whole IT world as multiple operating systems and multiple applications can be installed and configured on a single system that consumes up to 80% of the physical resources of the system.
By doing this, you can reduce the number of physical servers while saving power, cooling, and data centre footprints costs for your company.
3) Cost Reduction
Virtualisation and cloud computing eliminates the capital expense of buying hardware, software, and setting up and running on-site Data Centres, the racks of servers, the round-the-clock electricity for power and cooling, the IT experts for managing the infrastructure. It adds up fast and customers are more comfortable and productive due to less downtime and higher performance.
4) Backup / Restore
Backing up and restoring critical data and applications is the most demanding feature while running and managing critical applications and workloads. With VMware technologies, you can quickly backup and restore VMs, also take image-level backups while making disaster recovery much easier.
You can also take snapshots of VMs before patching and updating particular applications, and if patching or updating doesn’t work, you can restore your VM on the previous state again using snapshots.
5) Moving to the Cloud
Virtualisation builds the foundation to move your workloads to the cloud without modifying VMware-based applications and customers can have great scalability and agility while maintaining continuity by using existing VMware-based tools, processes, and policies.
