The Shift Cloud Computing Brings to Disaster Recovery Mike Klein President, Online Tech June 21, 2010
Disasters Happen WHY DISASTER RECOVERY? How Do You Recover All of Your Electronic Assets? Recover Your Customer, Business & Financial Data? Assure Business Continuity? Survive?
Business Drivers & Tradeoffs Business Drivers Recovery Time Objective (RTO) Recovery Point Objective (RPO) By Applications Budget Constraints Technical Tradeoffs Pipe Size Between Data Centers Backup Disaster Recovery (Failover) Multi-Site Availability (Failback) Shared or Dedicated D/R Servers 100% or Diminished Capacity
Traditional D/R Trade-offs Seconds Hot Site DR Recovery Time Warm Site DR Cold Site DR (SunGard) Online Backup Days Offsite Tape (Iron Mountain) Tape Backup/Trunk $ Cost $$$$
What Changes in the Cloud? VIRTUALIZATION & HARDWARE INDEPENDENCE Once you virtualize into the cloud Entire virtual server can be backed up to a 2 nd data center Hardware independent OS, apps & patches already in place Creates more cost effective D/R options
The Cloud Shifts D/R Curve Seconds Recovery Time Online Backup 1 Disaster Recovery 2 Multi-Site Availability 3 Days $ Cost $$$$
Disaster Recovery Roadmap SAN SAN 4. Multi-Site Availability Failover & Fail Back SAN-SAN Replication 3. Disaster Recovery (Failover) Failover, No Failback Replicate to Target Servers Replicate Network Config 2. Offsite Backup Protect Your Data No Failover 1. Virtualize Your Servers Remove the Hardware Dependencies
1: Virtualize SEVERAL CLOUD OPTIONS 1. High Availability Private Cloud: Dedicated Hosts, Network & SAN Scale hardware over time 2. High Availability Managed Cloud Shared Hosts & SAN Hardware Buy by the Slice (Virtual Server) SAN SAN
2: Offsite Backup PROTECT YOUR DATA Offsite Data Backup Back up the virtual server to offsite data center Recovery time: measured in days Key dependencies: Find server for recovery Restore server Replicate network from production OTBackup
3: Disaster Recovery PROTECT YOUR SERVERS & NETWORK Warm Site Disaster Recovery Backup to offsite to target host Replicate production network configuration D/R failover testing Recovery time: measured in hours
4: Multi-Site Availability PROTECT YOUR SERVERS & NETWORK SAN Multi-Site Availability Failover with SAN-to-SAN replication Failback through reverse replication Pre-configured network Live failover/failback testing Recovery time: measured in minutes SAN
Disaster Recovery Options CLOUD COMPUTING RECOVERY OPTIONS Recovery Time Objective (RTO) Recovery Point Objective (RPO) Offsite Backup Disaster Recovery Multi-Site Availability Days Hours Minutes 24 Hours (Typically) 1 24 Hours Minutes Recovery HW None Shared or Dedicated Dedicated Failover No Yes Yes Fail back No No Yes Critical Path to Recovery Server Hardware, VM install, Network Network Failover Network Failover Cost $ $$ $$$
Wrap Up Cloud Delivers a Sea Change in DR Options RTO, RPO & Budget are Key Business Drivers Offsite Backup is Minimum Ante Failover/Failback Drive Technical Solution
