Migration to Cloud ComputingWhile many have started to implement virtual resources, the average infrastructure is still
only about 40-50% virtualized. There is still much to be done to complete the journey to true cloud computing.

The commercial marketplace has looked at the 1st generation of cloud computing and sees solutions that fit best for the consumer and casual user.
1st Generation Cloud Solutions
Security• Public Cloud oriented for all who want access
• Limited data security
• Cannot meet government regulations or company policies
Connectivity• Internet-based
• Presents security, availability and performance concerns
Resiliency/Service Quality• Wide fluctuations in availability
• Overall availability only about 95%
• Not good enough for the business world of 24 X 7 !

Adoption Issues: Security
Perimeter Security
Infrastructure Security
Event Monitoring & Reporting
Security Processes & Procedures
Data Security
Most IT Executives view 1st Generation Cloud as not being secure enough for the needs of the enterprise and that the only plausible alternative is to build their own private cloud.
9
Adoption Issues: ConnectivityThe 1st Generation of Cloud Connectivity have produced inconsistencies that have caused
major concerns for the enterprise.
Security
Latency
Availability
Moore’s Law of Internet Latency:“ As long as Internet users do not pay for the absolute amount of data bandwidth which they consume,Internet service quality (latency) will continue to be variable and often poor”.
10
Adoption Issues: Resiliency/Service QualityEnterprise applications have “industrial grade” requirements that are part of a broader set of
risk management policies.
Availability
Performance

Enterprise Cloud Solutions
Secure• Using low latency DWDM connections, VMs could reside on customer’s network fully
leveraging their network security
• A design that uses the latest in data at rest encryption, intrusion protection, breach monitoring and audit reporting
High Performance• An infrastructure platform powered by leading hardware & software technologies for
maximum bandwidth, storage and performance
• A management platform enables self-service “on-demand”
Industrial Grade• A highly secure solution designed to optimize capacity, performance and reliability
• Solutions capable of handling the requirements of enterprise applications
Enterprise Cloud Solutions should be based on key design principles such as these:
12
Enterprise Cloud Services
Next Generation IaaS providers for the enterprise should be able to offer three different types of services.
Self-Service• Self-service Portal
• SHI or customer provided templates
• Ability to configure VMs (CPU, Memory, Storage & Network Bandwidth)
• Wide variety of software applications via Service Catalog
Time-Boxed Burst Computing• Addresses seasonal capacity spikes
• A cloud center that provisions VMs using (customer-provided in advance) “gold images”
• A solution that eliminates need for large capital expenditures
Disaster Recovery• Innovative approach for customer’s with their own private cloud
• A cloud center that provisions VMs using (customer-provided in advance) “gold images” in the event of a disaster
13
Single Customer Federated Model
. Shared or Multi-TenantMulti-tenant or shared solutions run VMs on hardware shared by multiple customers with multiple levels of isolation. The potential cost savings benefit of a shared platform makes this an attractive option for non mission-critical applications.
Private or DedicatedFeature VMs running in the cloud provider’s center running on hardware dedicated to a specific customer
Managed PrivateEnables VMs to be deployed within the customer’s data center while being remotely monitored and managed by the cloud provider
Enterprise customers should be able to choose three ways to implement the “hybrid” strategy most want.
14
Infrastructure: Performance, Capacity & Reliability
Storage Storage Storage
Enclosure &Blade Servers
Network Switches
SAN EncryptionSwitches
VMware vSphere
Cloud infrastructure platforms should be designed to optimize Performance, Capacity and Reliability by providing multiple interconnects, maximum bandwidth and redundancy. The design should assure no single points of failure, with unmatched connectivity and security.
• No Single Points of Failure• Multiple Enclosures,
Switches, Servers and Storage Connections for maximum resiliency
• Virtual Fabric Technology for virtualized connections and easy manipulation of bandwidth to meet SLAs
• VMware High Availability to “fail over” to 2nd VM
• VMware Fault Tolerant provides 2nd “hot VM” for fail over
15
Data SecurityThe infrastructure platform (servers, storage and networking) should be designed for the data security
needs of the enterprise. SAN encryption switches using software encryption key management can provide a standard feature for both multi-tenant and private cloud infrastructure residing in a cloud center.
16
Powering the Cloud
A cloud management platform is an automated, fully managed platform that combines to enable on-demand provisioning of VMs.
A cloud management platform should provide:• Portal access for self-service and
centralized management
• Rapid deployment of VMs
• Automated provisioning of infrastructure
• Managed provisioning of application software from service catalog
• Comprehensive reporting for capacity, performance, service level, usage and auditing
Functional view of aCloud Management Platform
17
Security for the EnterpriseCloud providers should have a multi-layered solution to assure a multi-tenant or shared
enterprise cloud is secure enough to meet the requirements of enterprise-class applications. The same design should apply to a dedicated (private cloud) platform.
Security Processes(Industry Best Practices, Standardized,Tested)
Event Monitoring(Comprehensive & Supplemented by Trusted Third-Party)
Perimeter Security(Access Control, Anomaly-Aware, Customer Transparent)
Infrastructure Security(Layered Cloud Management Protection and Change Control)
Customer Data Security(Encryption/Segregation)
18
The first generation of cloud services focused on Internet connectivity. The Next Generation of cloud for the enterprise should be able to offer excellent diversity in connectivity.
Customers should be able to connect via MPLS or IPsec VPN.) Most cloud service providers only offer IPSec VPN. However, there is a better way.

Connectivity for the EnterpriseIt is possible to design a networking solution that offers complete isolation of customer
networks leveraging MPLS and VLAN down to the VM. Once VMs are provisioned they would appear on the customer’s data network. This is a critical capability for enterprise applications.
20
• Virtualized Switch Fabric with automated re-routing
• Intelligent management of network profiles
• 10GbE end to end, multi-link trunks for resiliency
• MPLS and 4094 VLANs down to the vCore
• 802.1QinQ Metro Ethernet support
•Single and double VLAN mapping/translation support
Key Design Features
Open Packaging & Distribution
Enables Optimized Distribution Provides A Simple Automated
User Experience Supports Single & Multi VM Configurations Enables Portable VM Packaging Affords Vendor & Platform Independence
Cloud providers should use Open Virtualization Format (OVF), a platform independent, efficient, open packaging and distribution format for VMs. OVF facilitates the ease of
migration to cloud environments and enables customers to have the mobility of VMs to the virtualization platform of their choice.
21
Migration ApproachLook for cloud services that provide an approach that will result in a balanced roadmap
incorporating innovation, tempered with recognition of infrastructure maturity levels, constraints and risk.

Migration – Financial Considerations
Key Financial Drivers:
Savings Opportunities:
TCO v ROI:
Current Level of Virtualization Current Level of Automation Desire to Reduce Capital Expenditures v Operating Expenditures Desire to Redeploy Resources
Virtualization Software Licenses & Support CMP Software Licenses & Support Servers, Storage and Networking Assets Data Center Space, Power & Cooling Certain Resource Costs
Custom Private Clouds Can Require Substantial Capital & Operation Expenditures Comparison of Current and Target State TCO and ROI Analysis is Recommended Moving to Service Provider Clouds Requires No Capital Expenditure For These “Buy” Scenarios, Current/Target State TCO Analysis is Recommended
TCO Models are available to assist customers with developing their business case for cloud with TCO reductions of 20-40%.
