6. What is the Definition of a Private Cloud? - wikipedia Private cloud is infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally.[41] They have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from lower up-front capital costs and less hands-on management,[42] essentially "[lacking] the economic model that makes cloud computing such an intriguing concept".[43][44] • 41^ abc"The NIST Definition of Cloud Computing (Draft)".

7. What is the Definition of a Private Cloud? • We have a private cloud in our shop. All of our servers are virtualized and we can create and manage them through a web-based portal (ubiquity and service oriented). Many VMs share the physical infrastructure (utility computing). © 2011 Unisys Corporation. All rights reserved.

13. Self-Provisioning Portal – What If??? • We installed a self-service portal in front of vCenter • We Allow end users to provision VMs • VMs for various business units were isolated (multi-tenant) • We simplified the physical server provisioning process • VMs were allocated on a leased basis • We did 3 things - Automate, Automate, Automate This is a true story.

21. Enterprise Private Cloud – The Value of the Invisible • Automate Application Management – When VMs are created, agents are automatically embedded for backup , performance and capacity management • Automated Asset Tracking – When VMs are created, the Configuration Item is automatically updated in the CMDB • Automate incident management – incidents are automatically sent during the provisioning process • Automate performance and capacity management – insert agents and automate updates for the collection process • Automate VM provisioning tasks – Standardize the VM templates and automatically allocate them based on pre-determined approval schemes • Automate Security– Establish tiers and tenants so that they can be automatically isolated using vLAN technology or more sophisticated encryption technology • Automate Identity and Access Management federation – Single sign-on and seamless management from datacenter management to cloud management © 2011 Unisys Corporation.

Capacity Planning • A well defined Capacity Planning Process is required to achieve a cloud-like environment in a shared infrastructure • Automated periodic reports • Understand to cadence of growth as well as your supply chain • Service Level Objectives • Increase 10% of the resources within 2 days • Increase 25% of the infrastructure within 5 days • If a cluster consists of n servers, add more servers if n-1 servers exceeds 80% utilization © 2011 Unisys Corporation.
