Here at VMware, we want users to be sure that they’ve chosen a public cloud service provider that meets all of their needs. That’s why we’ve created The 10 Big Questions – they are the 10 main questions that every user should ask prospective cloud providers, because a great cloud provider should be able to answer them. Here are the questions:

  1. Do I have to re-write or modify my applications?
  2. Can I move applications back and forth to the public cloud?
  3. How do I know if my cloud is secure?
  4. Can I get flexible role-based access control synchronized with my enterprise directory?
  5. Can I get virtual layer 2 networking and a stateful virtual firewall?
  6. Can I dynamically add memory and CPU to a cloud VM while it’s running?
  7. How can I ensure CPU and memory are guaranteed?
  8. Can I get predictable service costs that still allow me to scale when I need to?
  9. How can I get the cost benefits of multi-tenancy but still access dedicated infrastructure when I need it?
  10. How can I ensure global consistency across cloud service providers? 

There they are, the 10 things every user should be asking prospective cloud providers. With the new VMware vCloud Datacenter Service, offered by a select network of leading service providers, VMware has actually answered all of these questions. Here’s how we stack up:

1. Do I have to re-write or modify my applications?
Nope, not with VMware vCloud Datacenter Service – it functions as an extension to existing VMware-virtualized datacenters. This means that users can move their applications to the cloud with little or no re-work!

2. Can I move applications back and forth to the public cloud?
Absolutely. VMware vCloud Datacenter Service makes it simple for users to transfer VMs from their on-premise vSphere or vCloud Director infrastructure to the cloud and back again, as often as they want. 

3. How do I know if my cloud is secure?
VMware vCloud director has a published set of security controls that VMware cloud partners must adhere to. That means users can always obtain firewall and other security logs, as well as security transparency and the ability to audit.

4. Can I get flexible role-based access control synchronized with my enterprise directory?
VMware vCloud Datacenter Service authenticates using users’ own enterprise directories, so they don’t have to administer a shadow user list. Role-based access control ensures that users get all the control they need to manage their directories.

5. Can I get virtual layer 2 networking and a stateful virtual firewall?
Yup, VMware vCloud Datacenter Service offers a stateful firewall per virtual application, and full virtual layer 2 networking.

6. Can I dynamically add memory and CPU to a cloud VM while it’s running?
VMware vCloud Datacenter Service allows users to dynamically add or remove resources both to and from running VMs, giving them dynamic scale.

7. How can I ensure CPU and memory are guaranteed?
The same VMware vSphere resource controls that people use today to guarantee performance are available through VMware vCloud Datacenter Service. This means that users can get guaranteed reservations, even when they’re sharing the cloud with other tenants.

8. Can I get predictable service costs that still allow me to scale when I need to?
VMware vCloud Datacenter Service provides Virtual Datacenters (VDCs), a collection of CPU, memory and storage, all with predictable costs. Users can then allow self-service or delegated consumption of resources, giving elastic scaling while still maintaining the same predictable costs.

9. How can I get the cost benefits of multi-tenancy but still access dedicated infrastructure when I need it?
VMware vCloud Datacenter Service actually offers both multi-tenant (shared) infrastructure and dedicated (virtual private) Virtual Datacenters. 

10. How can I ensure global consistency across cloud service providers?
Users can achieve global consistency by working with any of our great service provider partners who offer VMware vCloud Datacenter Service. All vCloud Datacenter Services are regularly certified by VMware and are build on a common infrastructure platform—ensuring that users receive the same quality service, no matter which partner they access it through or which part of the world they’re accessing it from.

We’re excited by the new cloud benefits we can provide to customers through VMware vCloud Datacenter Service. To learn more, be sure to visit us online and follow the @vCloud channel for future updates.
