Each repository and topology packaged into a virtual Cloud Container similar the idea of shipping containers filled with server racks.
The process involves five steps to reach Disaster Readiness, and another 3 steps to have a working Disaster Recovery facility operational. The steps are:
Step 1: Choose Your Cloud
Select a public cloud(s) to meet your scaling, geographic, technology, and vendor diversification needs.
Step 2: Build a Secure Environment You Control
Create a controllable and secure virtual overlay network on top of the cloud provider's physical network.
Step 3: Test Scaling and Failure Modes
Even before any IP or data is moved to the cloud, you have reduced your application's recovery time objective (RTO).
Step 4: Migrate Your Application Repository
Deploying copies of the digital assets needed for recovery.
Step 5: Commence Data Synchronization
Implement a the simplest workable method for synchronizing production data to the repository.
Disaster Readiness Accomplished!
You have narrowed your RTO by staging what you need to bring up the application in the cloud providers' facilities. And, you have establish a process for moving data to the cloud facility, which means your RPO is a a much more known and fixed down-time risk. Hold here until disaster strikes or to further tighten the recovery window, continue:
Step 6: Define & Deploy the Application Topology
Decide on an aspirational topology and deploying a scaled down version of your production systems.
Step 7: Process Live Data
Run select transactions through the Disaster Recovery facility as an extension of production.
Step 8: Conduct Periodic Disaster Drills
At this step the Disaster Recovery facility is fully operational, now your attention can turn to preparedness.
