Efficiency
29
3 Areas of Cost Savings (& Typical Amounts) in a VDC
1. Hardware - 50% 2. Energy - 80% 3. Provisioning - 70%
30
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.
31
Waste reduction translates into what?
Savings in capital expenses
32
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.
33
Single use infrastructures can be collapsed into what?
Shared infrastructures with various tiers of service.
34
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.
35
What can happen in 60 seconds on the Internet?
``` 40,000+ iPhone applications downloaded. 168M emails sent. 1.5M Google search queries. 600+ new YouTube videos. 98,000+ tweets 695K Facebook status updates; 75K wall posts; 500K comments ```
36
5 Characteristics (Tenets) of the Cloud

39
Three Cloud Layers or Service Models
Top Layer: Software-as-a-Service (SaaS) Middle Layer: Platform-as-a-Service (PaaS) Bottom Layer: Infrastructure-as-a-Service (IaaS)
40
Big Advantage of Cloud
The big advantage of the Cloud is speed and agility to the business.
41
6 Cloud Benefits
1. Self-service provisioning (minutes vs. weeks) 2. App development & testing are flexible & self-service enabled. 3. Relocation from test & development to production is predictable & seamless. 4. Resources scale fluidly to meet growing or reduced need. 5. Service level easily adjusted after the fact. 6. Resources granularly metered to optimize utilization & cost.
42
Cloud benefits for IT
Moving toward self-service access. Ability to align costs with use. Greater flexibility to change.
43
Cloud Benefits for Business
Increase in efficiency & control from greater task automation.
44
Cloud Benefits for the Attention-Span-Challenged
IT has more time to focus on the strategic. LOB has more time to focus on the business.
45

48
Phases which move from a physical infrastructure to a full IT-as-a-Service implementation
1. Virtualize 2. Operationalize 3. IT-as-a-Service
49
Phase where IT is now a utility to the business
IT-as-a-Service
50
Phase where IT services are maintained in a service catalog that is open and easily extended as needed.
IT-as-a-Service
51
Phase where ownership is primarily IT, working with a high CAPEX-based budget.
Virtualize
52
Phase where the business and IT derive additional savings by further consolidation and by using more generalized resource pools.
Operationalize
53
LOB
Lines of Business
54
Advantages of IT-as-a-Service to LOBs
1. Get resources or deploy new apps in a self-service manner. 2. Have fine-grained reporting on resource utilization and costs. 3. Enjoy the benefits of true business agility with the use of IT as a competitive advantage.
55
During this phase, the environment generally becomes on-demand, which meets or exceeds its service level targets.
Operationalize
56
First phase of virtualizing
To move from dedicated to consolidate resources.
57
The move from dedicated resources to consolidated resources includes what?
Employing server virtualization, tiered storage, and partially integrated management.
58
Result of move from dedicated resources to consolidated resources.
Reduced power and space costs in the DC, as well as increased storage administrator and server administrator productivity.
59
Benefits of Consolidated Resources
``` Reduced power & space costs. Reduced data center equipment costs. Increased storage admin productivity. Increased energy efficiency. Reduced CO2 footprint. ```
60
Second phase
Takes a consolidated environment and operationalizes it.
61
Included in operationalize phase
Employing tiered virtual servers and storage optimization structured in resource pools based on security, availability, performance, and governance requirements.
62
Resource pools can be based on what?
Security, availability, performance, and governance requirements.
63
Key enablers for the success of the operationalize phase
Integrated management and security
64
Benefits of operationalize phase
``` OPEX savings Data center equipment savings OS images virtualized Mission-critical applications include virtual components Reduced CO2 ```
65
Last step in migration
Last step is to transition from a fully shared, tiered infrastructure to IT-as-a-Service.
66
What does transition from a fully shared, tiered infrastructure to IT-as-a-Service mean?
Both development platform and service-based software is self-service and multi-tenant.
67
Examples of integrated development environments
J2EE .NET
68
How does IT-as-a-Service benefit developers?
Developers can choose different integrated development environments (e.g., J2EE or .NET) and deploy their applications to QA/Dev/Test and then on to production via self-service capabilities.
69
Benefit of IT-as-a-Service to end users
End users can potentially bind different services together from the service catalog. For example, they can use Google Maps with Salesforce.com to generate directions to a customer site.
70
Part of the IT-as-a-Service phase that shows the business exactly what services are consumed and who is consuming them.
Either a full fine-grained chargeback or a showback capability
71
How are security and GRC handled in the IT-as-a-Service phase?
Security and GRC are embedded into the services using specific trust zones.
72
GRC
Governance Risk Compliance
73
New IT Focus areas
Cloud service | Operations management
74
New IT roles emerging
Cloud Architect Cloud Admin Cloud Capacity Planner IT Automation Engineer
75
What happens to the role of the VM administrator in the virtualized environment?
In the virtualized environment, the role of the VM administrator evolves (as tools evolve) to include fully managing storage.
76
Shift in IT roles
Less time is spent performing manual tasks, such as change management, while more time is devoted to tasks that have a broader impact, such as creating templates and performing automated rolling upgrades.
77
What are two (2) benefits of a VDC? 1. Increased security and privacy through multi-tenancy. 2. Application level business continuance and resource mgmt. 3. Centralized management and optimized provisioned resources. 4. Near zero downtime guarantee and improved performance. 5. It is a required step for cloud computing.
2. Application level business continuance and resource mgmt. | 3. Centralized management and optimized provisioned resources.
78
Simple definition of a cloud
Shared services delivered from the network to any device.
79
How is a VDC different 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 LOB ownership.
80
Steps recommended to prepare for Cloud computing
Virtualize the mission critical applications. | Retire all the non-virtualized applications.
81
Why resource pooling through virtualization is essential
Improves efficiency. Creates secure and trusted environments. More responsive to on-demand growth.
82
Ways the Cloud extends benefits of the VDC
Further improves cost structure. | Puts IT in the hands of the customer.
83

88
Best way to match the information growth rate and evolve the business to manage information instead of manage the infrastructure.
Virtualizing all the layers in the data center, creating resource pools, and driving IT to become completely services-based.
