There are many myths around Disaster Recovery: That it's a nice to have, or expensive, or just another type of needless insurance - or that all the options are the same. None of this is true. Sadly, businesses find out every day to their cost that they need Disaster Recovery, often when it's too late. If you ask us, Disaster Recovery as a Service is one of, if not the best use of cloud computing so far. We strongly advise you engage a partner who can deliver the Disaster Recovery plan you need (and your needs will be specific to your business). And we are more than happy to discuss your needs and your options with you without any obligation. We have options for you to choose from too. The two main DRaaS offerings being what we call Hot DRaaS and Cold DRaaS...
Always On - One Button Failover
This solution uses a combination of standard VMware tools that run both on premises and in the Software Defined Datacenter (SDDC) in the AWS platform. This consists of a minimum of 3 hosts deployed in the SDDC and all the networking and services defined to support failover using the SRM packages.
This version can run any compliant version of VMware up to and including VMware 7.0. The system uses VMware replication to a defined vSAN in the SDDC which then allows the system to perform failover using the SRM functionality. Because the SDDC is previously designed, the failover works according to the SRM plans.

Advantages
Considerations
This is a very powerful option for those looking for an
instant, one button failover
that provides
minimal downtime
- usually less than an hour.
Rather than spinning up when you need it, it's
always on. It costs more, but is more cost effective when running.
Hot DRaaS is recommended for those who require near zero RPO and RTO.

There When You Need It
The architecture of DRaaS uses a connector services installed within live system which then replicates the VMware data to a cloud store (SCFS). This is not replicated using VMware replication, but uses a customised version reliant on Change Block Tracking (CBT) on the originating VMs. This is similar to a backup product, such as Veeam, which uses the CBT to take the backups of the system.
The SDDC is created during the activation with the minimum of 3 hosts to initiate the failover. The process takes 90 minutes to configure the SDDC and then 45 minutes to deploy the initial host configuration. An additional 15 minutes is required to add a host, but critical workloads can begin failover from the 2:15 hour mark.
Additional time is required to create the correct SDDC configuration. This includes defining internal network, NAT rules, firewall rules, and other objects that are required to run the DR service. Also, any external facing resources, such as public IP addresses would need to be requested at this point and external services mapped to this address via DNS or GSLB services. These objects can be provisioned by script but would also need maintaining and testing in the event of changes to the production environment.

Advantages
Considerations
This is a
cost-effective
option for those who can absorb a slightly longer downtime window in the event of Disaster Recovery for the benefit of reduced costs when not required.
Rather than always being on, this spins up
when required, and requires slightly more manual intervention.
