Simplified Disaster Recovery
Backup and restoring are easy and beneficial for a quick recovery of critical applications and data in unexpected situations.
Test Environments
You can create multiple test environments in one physical server. This approach provides the best results for efficient application development and testing without needing additional VMs.
Disadvantages of VMs
Some factors may make virtual servers a wrong choice for your business because they can affect the performance and security of your application –
- Noisy neighbors when sharing the same physical resources
- Hypervisor overhead creates a virtual layer for resource allocation and it can be resource-intensive, especially under heavy workloads.
- Security risks due to shared resources.
- Latency concerns can arise due to the hypervisor as it affects the responsiveness of applications running on VMs.
- Resource scaling is limited by the underlying physical server’s resources.
