9 IT Challenges
Acquisitions Aging Data Centers Application Explosion Complexity Cost of Ownership Globalization Security Storage Growth Time To Market
Impact of Globalization
Business at all hours 24x7x365
Impact of Aging Data Centers
Migration, upgrading technology to replace old technology
Impact of Storage Growth
Explosion of storage consumption and usage
Impact of Application Explosion
Applications can be deployed and expand their usage rapidly.
Infrastructure has not been planned to scale for rapid growth.
Impact of Cost of Ownership
Cost of the growth (i.e., equipment, power, cooling, support, licenses, etc.) to meet demand makes scaling difficult.
Impact of Security
Challenges related to governance and risk
Impact of 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.
Impact of Acquisitions
When companies make acquisitions, the IT infrastructures are often different due to the use of different preferred vendors.
A highly efficient and optimized data center allowing the business to do more within the confines of the available resources (servers, power, cooling, sq. ft.). It also has the agility to adapt to changes in the business and workload requirements.
Virtualized Data Center (VDC)
5 Key Characteristics of a VDC which provide the most beneficial return when moving from virtualization to a VDC
Automation Reporting for management and chargeback Resource pooling / shared resources Standardization Virtualized Hardware Stack
4 Benefits provided by secure desktops
- Central management with the use of templates.
- Gold copy patching
- Rolling upgrades
- Improved contractor / consultant control (e.g., custom template for contractors that doesn’t allow USBs)
In order to align BC requirements to business requirements, it is important to focus on what?
Application-level Business Continuity
How is the need to further optimize resources for increased availability and improved productivity realized (or accomplished)?
By continued consolidation of all the infrastructure layers: servers, storage, and networks.
6 VDC Benefits
Lower hardware, power, and space requirements.
Quickly and easily provision new servers into the environment.
Reallocate resources with no downtime.
Ensure applications remain online in a highly available architecture.
Prioritize the most important applications to ensure they receive the resources required to meet business needs.
Simplify and improve disaster recovery process.
How does a VDC simplify and improve disaster recovery processes?
By replicating VMs to another storage array, where they can be quickly started on any server.
How does a VDC lower hardware, power, and space requirements?
Due to the more efficient use of resources through server consolidation and centralization.
How can VDCs reallocate resources with no downtime?
By automatically migrating VMs with continuous load balancing.
How does a VDC ensure that applications remain online in a highly available architecture?
By migrating VMs in concert with data storage in the event of hardware failure.
How does a VDC prioritize the most important applications to ensure they receive the resources required to meet business needs?
By dynamically and intelligently allocating hardware resources.
How does a VDC enable quick and easy provisioning of new servers into the environment?
With easy provisioning and management tools.
3 High-Level VDC Business Drivers and Benefits
- Application-level Business Continuity (BC)
- Improved Productivity, Operational Flexibility, & Availability
- Secure Desktops
2 Benefits of Application-level Business Continuity (BC)
- Simplify and improve disaster recovery.
2. Ensure important applications receive resources required to meet business needs.
6 Benefits of Improved Productivity, Operational Flexibility, and Availability
- Optimize resources - consolidate servers, storage, & fabrics.
- Reduce HW, power, cooling & space requirements.
- Reallocate resources with no downtime.
- Quickly and easily provision new servers.
- Improved performance and availability.
- Simplify BC/DR strategies.
3 Benefits of Secure Desktops
- Centralize management.
- Patch gold copies once - standardization.
- Predictable change management with automated rollout.

Efficiency
3 Areas of Cost Savings (& Typical Amounts) in a VDC
- Hardware - 50%
- Energy - 80%
- Provisioning - 70%
Fundamentally, how is efficiency achieved in a VDC?
By consolidating the physical resources, which happens through creating resource pools that are designed to support more generalized workloads across applications.
Waste reduction translates into what?
Savings in capital expenses
How can operational savings by achieved?
By using standardized templates, reducing the number of custom configurations, and having the ability to provision more closely to actual usage.
Single use infrastructures can be collapsed into what?
Shared infrastructures with various tiers of service.
What happens with virtualization?
A subset of physical infrastructure can be configured into pools of resources, which can then be provisioned as needed. When those resources are no longer needed, they can be returned to the pool.
What can happen in 60 seconds on the Internet?
