Database virtualization
Right!
- High availability / HA redundancy
- Non-disconnected and reconnected hot load balancing application services
- Fast horizontal scaling of other database instances
- Database virtualization is a tiered cluster database approach to eliminate underused servers .
- In general, the primary purpose of virtualization is to eliminate underused servers. Should you mix production database and non-production database payloads on the same physical host? In a VMware environment, it's perfectly fine, as long as you don't over-use resources so that the production load cannot get the corresponding resources.
- Hierarchical cluster database in virtualization
- Layering a database vendor's clustering technology on top of virtualization has the following benefits:
- The ultimate obstacle to database virtualization
- Generally speaking, the biggest challenge of database virtualization is not technical but administrative. In the local environment, CPU usage continues to decline. Many corporate customers seem to expect their servers to maintain average CPU utilization at a dozen percent. If you only want to pay one database license fee for all host CPUs, you should consider ways to promote license utilization. [1]
