VDCIPD Module 1 Flashcards
What is a VDC and how is it diffrent from implementing virtualization?
A VDC takes virtualization to the next level by creating shared resource pools based on requirements instead of individual application needs or line of business ownership
Module Test
what are 2 benefits of VDC
Centralized management and optimzed provisioned resources
Module Test
What is a simple definition of Cloud
Shared services delivered from the network to any device
Moduke Test
What steps do you recommend to prepare for Cloud Computing
Virtualize Everything, create shared resource pools using standardized hardware and software
Module Test
What are Key IT challenges
Globalization – business at all hours 24x7x365.
•Aging data centers – migration, upgrading technology to replace old technology.
•Storage growth – explosion of storage consumption and usage.
•Application explosion – applications can be deployed and expand their usage rapidly. Infrastructure has not been planned to scale for rapid growth.
•Cost of ownership – cost of the growth (i.e., equipment, power, cooling, support, licenses, etc.) to meet demand makes scaling difficult.
•Security – challenges related to governance and risk.
•Complexity – lack of physical access to the environment; it may be spread across wide geographic locations. There could be globally distributed processes using content balancers to meet user demand. This can be expensive and time consuming.
•Acquisitions – when companies make acquisitions, the IT infrastructures are often different due to the use of different preferred vendors.

Other VDC business drivers and benefits
Productivity flexibility, availability
BC
•Lower hardware, power, and space requirements Due to the more efficient use of resources through server consolidation and centralization
Quickly and easily provision new servers into the environment With easy provisioning and management tools
Reallocate resources with no downtime, Automatically migrate VMs with continuous load balancing
Ensure applications remain online in a highly available architecture Migrate VMs in concert with data storage in the event of hardware failure
Prioritize the most important applications to ensure they receive the resources required to meet business needs dynamically and intelligently allocate hardware resources
Simplify and improve disaster recovery process.Replicate VMs to another storage array, where they can be quickly started on any server
