vCloud Air


Did you know vCloud Air currently supports over 5,000 applications and over 90 operating system? 

To design a vCloud Air solution follow these simple steps:

First, draw out your environment and determine resource requirements per virtual machine.  

For example:

  • How many VMs?
    • What is the operating system on each VM (linux, windows 2012, etc).
    • What is running in each VM (Network Security Appliance, Replication Appliance, Sharepoint, SQL, Active Directory, file server, etc).
  • How many vCPUs are needed per VM?
  • How much vRAM is needed per VM?
  • How much Storage is needed per VM?
  • How many IOPS are needed across all VMs?
    • Standard Storage: 200 IOPS Average
    • SSD Storage: 500 IOPS Average
  • Is your standard network bandwidth reliable, safe and fast enough to support the link between onsite or co-located data center and your vCloud Air environment?

Second, use the Pricing Calculator to help price out your custom solution:

Third, you will need to determine your Microsoft licensing costs.

Although Microsoft authorizes customers with Volume License Agreements and Software Assurance to move most server-based applications to vCloud Air, Windows Server 2012 and Windows Server 2008 are currently not eligible for License Mobility. Your licensing options for Windows Server will depend on what type of vCloud Air configuration you select.

With vCloud Air Virtual Private Cloud Microsoft requires all customers on multi-tenant public cloud environments such as vCloud Air Virtual Private Cloud to purchase Windows Server licenses from the cloud service provider (eg VMware). If you import a Virtual Machine or vApp into vCloud Air, VMware will automatically detect the presence of Windows Server and will bill you the standard rate for running Windows Server on vCloud Hybrid Service, in compliance with the VMware Microsoft Service Provider License Agreement (SPLA). If you host your workloads on vCloud Air Virtual Private Cloud, you will authenticate your Windows Server instances against VMware’s Key Management Server; this enables you to re-purpose the license keys of the instances you imported for other on-premise workloads.

With vCloud Air Dedicated Cloud you’re provided with a single-tenant private cloud with physically isolated compute, a dedicated cloud management stack, and logically isolated networking and storage, so it can be considered a dedicated server from a licensing perspective. Microsoft allows customers to move a Windows Server license to a dedicated server (See: Product Use Rights – Outsourcing Software Management). You may also purchase your Windows Server Licenses through the catalog for vCloud Air on a subscription basis.

Fourth, understand all Service Level Agreements for VMware vCloud Air (SLA)

So what does a 99.95% Availability SLA actually equate to?

Well “Availability” = ((total minutes in a calendar month – total minutes unavailable) / total minutes in a calendar month) x 100

So for example there are 1440 Minutes in a day or on average 43200 minutes per month.

In our example lets accept only 1 minute unavailable per day or an average of 30 minutes per month.

– 43200-30 = 43,170

– 43,170/43,200 = .9993

– .9993 x 100 = 99.93%
