  3. 3. Using Traditional Virtualization  Key benefit: Lower costs through server consolidation IT User A VM A VM VM VM Hypervisors Compute/Storage/Networking 3) Manually create resource 1) Request resource (e.g., VM) from administrator VM Management Tool VM Admin 2) Verify that request is allowed
  4. 4. Using a Private Cloud  Key benefit: Faster, simpler, cheaper deployment of VMs and applications 2) Request resource (e.g., VM) directly from cloud Self-Service Portal IT User A A VM VM VM VM Cloud Cloud 1) Create clouds with predefined services, users, access rights, and quotas Hypervisors Compute/Storage/Networking VM and Cloud Management Tools VM Admin
  5. 5. Evaluating Private Clouds Benefits Risks Faster deployment of VMs and applications, because the process is automated VM administrators find it hard to trust users to deploy their own VMs and applications Reduced administrative costs, because more of the process is automated VM administrators might resist having part of their job automated Fewer deployment errors, due to automated deployment of standard services Defining standard services can be challenging, since users want different things Easier cost management, with per-VM chargeback or showback Changing operational processes is hard for risk-averse IT departments
  6. 6. Using a Private Cloud: Example Scenarios  A dev/test group getting VMs on demand  A central IT organization in a multi-division company providing VMs and applications to business unit IT staff in their organization  A CIO demonstrating innovation
  7. 7. Private Cloud or Public Cloud?  Private clouds can make internal data centers more efficient ‒ They provide IaaS in your data center ‒ They’re the evolution of virtualization  But public cloud platforms are the best choice for many new applications ‒ Such as apps that require elastic capacity  Organizations will likely use both ‒ It’s not an either/or decision
  8. 8. Combining Private and Public Clouds  A service provider (e.g., a hoster) can provide a public IaaS cloud using the same technology that an enterprise uses to create a private cloud ‒ The public and private cloud can be linked together in a hybrid cloud ‒ VMs can potentially be moved between the two  Example scenarios: ‒ Quickly getting VMs with minimal commitment ‒ Offloading work to the public cloud when more resources are needed

  11. 11. The Impact of Private Clouds  Private clouds aren’t a substitute for public clouds ‒ The two address different problems  For many organizations, adopting private clouds is easier than adopting public clouds ‒ The risks are easier to bear  Enterprises are likely to adopt private clouds rapidly
  12. 12. Conclusions  Cloud computing is here  All three aspects are important: ‒ Cloud applications ‒ Cloud platforms ‒ Private clouds  A new world is unfolding ‒ Prepare to be part of it
