Things to consider: ✓ Define affinity rules for your VMs. For example, you can define host affinity rules to keep VMs together, so a web server VM and its associated app and database VM are kept on the same physical server for high- speed virtual network connectivity. You can also define anti-affinity rules. For example, you can keep multiple database servers on separate hosts so if a physical host fails, other database VMs will keep running. ✓ Determine whether your applications must reside on specific hardware for compliance or process reasons. ✓ Make sure you determine the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for each workload, so when you're creating your busi- ness continuity and disaster recovery plans, your backup and recovery policies are aligned with your business priorities. Adding Operations Management As the saying goes, those who ignore history are doomed to repeat it. By monitoring performance issues, resource shortfalls and other historical data on your VMs, you can anticipate future spikes in memory
