Hi! My name is Gaurav Daga - I am a program manager on the Windows Azure Hyper-V Recovery Manager (HRM) product team, and my role is focused on hosting service providers (HSPs). With the general availability of the HRM service, we are starting to get a number of queries from HSPs on whether they can use HRM to provide a premium Disaster Recovery (DR) service to their tenants. And the answer is absolutely yes! This blog post describes the business and technical aspects of how HSPs can leverage HRM today to offer DR as a managed service for tenant workloads, and provides answers to many frequently asked HSP questions.
First, why should a HSP care about offering DR? DR as a service is a premium business with huge new revenue potential – Infrastructure as a Service (IaaS) Virtual Machine (VM) rentals carry as much as 30 to 70% premium when sold with DR capabilities versus without. It is also a great way for a HSP to acquire new customers because businesses these days are willing to pay serious money for a reliable DR plan. Providing DR as a service lets HSPs get a foot in the door of the customer and later have conversations to host more critical workloads and monetize them.
Next, why should a HSP use HRM to offer DR? There are many Do It Yourself (DIY) solutions available to automate DR that require a HSP to spend lot of time and effort building a solution and even then likely end up with something that results in customer dissatisfaction because DR has many complex challenges. HRM provides a packaged service offering that solves all these tough DR problems saving significant cost for the HSP who does not have to build a DIY solution and instead can focus on adding value and meeting customer SLAs, which in turn would translate to higher customer satisfaction and greater revenues. There is a great overview of HRM on Brad Anderson’s In the Cloud blog, and below is a summary of the salient points that cover the HRM value proposition.
· Automating DR infrastructure setup
· Automating DR failovers
· Automating DR networking at scale
· Reliable DR for compliance needs
· Single highly available DR management console across multiple sites
There are two use cases that a HSP will run into when looking to sell DR as a service – one is where the tenant’s workload is running on the HSP’s primary site and the HSP owns the recovery site too. And the other is where the tenant’s workload is running on their own enterprise network and they want to use the HSP’s data center only as the recovery site. This blog post describes how HRM today addresses the first use case where DR is happening between the HSP’s primary and secondary data centers, and within this context, it is important to understand the two main models of delivering DR as a service:
· Managed DR
· Self-service DR
In most cases, given the complexity associated with DR, we are seeing managed DR as a service solutions being offered by HSPs. And the first query we get - are HSPs even legally allowed to use HRM to offer DR? From a rights to use perspective, managed DR as a service with HRM is allowed per the Online Services Use Rights (look for the section titled “Windows Azure Services”) of the Service Provider License Agreement (SPLA). However, the HSP’s Windows Azure bill for HRM use will be separate from the rest of their SPLA bill and the available options to buy Windows Azure services are the following:
Now that you know that from a licensing perspective you can use HRM to offer DR to your tenants, let’s take a look at the frequently asked questions around providing managed DR as a service with HRM:
1. Do I need to share my tenants’ identities with Windows Azure?
2. Do my tenants need to go to Windows Azure management portal?
3. Does my tenants’ application data go to Windows Azure?
4. Do my Hyper-V hosts and applications need internet connectivity for the DR service to work?
5. Do I need to install one more System Center agent on each of my Hyper-V hosts and on each of the tenant guest VMs?
6. Can I use a single SCVMM server to manage both my primary and recovery sites?
7. How does an unplanned failover work when a disaster impacts both my primary site and my ISP?
8. A tenant’s n tier application is using SQL AlwaysOn – can I use HRM to orchestrate single click application failover?
9. How do I manage the health of replication of all protected tenant VMs?
10. Is there Windows Azure Pack (WAP) integration?
