The CloudEndure service also offers means by which to keep traditional cold site (or in this case region) costs down by not requiring parity between the two from a compute perspective. In essence you pay for the data storage in your secondary site and should the time come to leverage the site/region, automated runbooks created within the CloudEndure platform can be used to spin-up the required EC2 compute to support the fail-over effort(s).· Azure ­Microsoft customers interested in and/or currently leveraging Azure have use of the ASR (Azure Site Recovery) managed service which was created in-house at Microsoft but really began to take form after the June 2014 acquisition and later integration of InMage. InMage was a US/India based company specializing in the continuous data protection space through their Scout service. Similar to CloudEndure, ASR checks all the requisite boxes for a complete backup and recovery-as-a-service solution chief among those being:· Heterogeneous Workload Support for various different Windows and Linux editions· Automated Discovery of VMware vCenter Server managed virtual machines for replication and recovery· Continuous Data Protection with software-based replication to support stringent Recovery Point Objectives (RPO)· On the Fly Conversion of source Virtual Machine Disk (VMDK) files to bootable target Virtual Hard Disk (VHD) files· Active-Passive Replication that does not require running target virtual machines at the time of replication· Single-Click Failovers with Recovery Plans to provide workload-aware disaster recovery and orchestration· Health Monitoring for replication, failover and failback with events and notificationsNOTE:Azure Migrate is a similarly-aligned service to ASR, however it is focused exclusively as a cloud migration tool and is not intended for ongoing recovery and backup.· GCP ­Google unlike AWS and Azure, does not provide a formal DRaaS offering native to the platform. However,Google does providecomprehensive documentation on how to approach DR in GCPby explaining the key building blocks needed (e.g. use of GCP's Deployment Manager, use of Terraform/Ansible/Chef for automation,as well as recommendations related to 3rd party partners).Multi-Cloud Approach (Considerations for leveraging 3rd party migration/recovery toolsets)For more complex hybrid (public/private) and/or multi cloud (use of multiple CSPs) use cases, there are a number of 3rd party solutions in the DR-as-a-S space. · Zerto· Commvault· Cohesity· Veeam· Actifiio· DruvaEach of the above mentioned 3rd party solutions behave similarly to the CSP specific solutions we touched upon earlier albeit with the option to leverage not only to a specific cloud (e.g. Azure) across cloud providers (e.g. AWS, GCP). This allows for a level of flexibility for those who may need to move certain on-premise workloads to a given CSP based on supportability and/or function.Hybrid-Cloud Approach (For workloads that support cloud but entail on-premise dependencies)For organizations that host workloads that support public cloud but however be it for compliance and/or physical infrastructure requirement dependencies cannot persist entirely in cloud. There are a number of solutions to help solve for this situation based upon your hardware support needs.· VMware· Nutanix· HPE· NetAppp· CiscoIn effect what these solutions provide is a means to administer their systems on-premise and in the cloud from a single management plane. As well as provide the ability to shift workloads hosted within them as needed between on-premise and cloud without fear of having to re-platform/re-engineer in order to do so.ConclusionIn conclusion the overall maturity for back-up and recovery in the cloud has grown exponentially and has to a large extent become table stakes where it is now becoming difficult to judge one solution from the other unless there is an underlying infrastructure platform dependency that requires it.Cloud in general provides a great option for infrastructure and operations leaders who want to cost-effectively improve IT resilience while being mindful of potential resource deficiencies.
