What does Internet say? Top reasons why cloud projects fail.
Not understanding
your own requirements
Managing by magazine
Falling in love with the
technology too early
Lack of holistic architectural discipline
Lack of talent
These can be applied to any project. So what is unique about cloud projects then?

1. Wrong Reasons & Wrong TeamVetting out business reasons (why?) a must.
Questions to ask• Public Cloud vs Private Cloud vs Hybrid Clouds
- CapEx vs OpEx - Cost per VM per month- Cost per 1GB per month- Specific HW requirements
N/W Architect
Storage Architect
Virtualization/Systems Architect
App Architect
Security Architect
Traditional roles
Dev Ops Product Manager
New roles

Introspection Questionnaire
What is your business reason to deploy cloud? • Public cloud business • Consolidation of IT resources • Automations of IT (Self Service IT)• Reduce IT cost
What is the cost per VM per month your organization can live with? How is it comparable with public cloud?
Who is part of your IT change control board? • Check if you have end user representative in the mix
Who owns end user experience requirements?

2. Product Manager (or lack there of) Cloud transforms IT team into Product Team
Product team needs product manager • Revenue/Cost model for the cloud• Requirement list • User interaction • Demand planning responsibilities • Services definition

Introspection Questionnaire
Who is the owner of cost model for your cloud
Who is the owner of end user experience and workflow
Who is the owner of services definitions and pricing models
SPOC for all the software/hardware vendors involved

Introspection Questionnaire
How many cloud-era applications and enterprise applications do you have?
Does deployment of applications happen manually or programmatically?
What are the network/storage/system requirements from your applications?
What is your Application Life cycle management system?
Who provides licenses to OS as well as Applications?

Introspection Questionnaire
What is your existing isolation model and how it will map to cloud?
What is the process of acquiring a new storage volume and releasing one?
What is your snapshot policy?
What kind of network services do you offer to your existing users?
How do you support bare-metal provisioning?

5. Cloud Operations != Data Center OperationOperations Reinvented
Backup/Recovery Monitoring
Performance &
Patch Management
Multi Tenancy
Usage Metering
SLAs per
Account

Introspection Questionnaire
Who initiates backup procedures ? (User/System)
Can your monitoring system monitor at tenant/application level?
Who is in charge of patch management on templates? and live systems?
How do you define performance metrics (&SLA) in shared resources mode?
What us the patch process for cloud management system?

6. Platform does not do everything Platform is only as flexible as the design. It is easy to miss the nail
Architecture determines SLAs• Flexible Architecture drives flexible services • Wrong architecture can lead to very restrictive
service offerings
• Models.. Models.. Models. - Network and Isolation Models
- Basic, Advanced,
- Storage - Local, Tiered ,Tagged
- Compute - Hypervisor selection
© 2014 Citrix. Confidential.16
Introspection Questionnaire
What are the different compute services offerings you planned to have?
Do you plan to have tiered storage to your end users?
Does your application require bare-metal provisioning?
How many datacenters you would like your cloud to span across?
How does your end user access VM/Services?

7. Cloud is not a single productIncorrect mix of technologies could lead to complex systems to maintain
Resource Tier (Virtual/Physical Resources)
Resource Management Tier (allocation, security, pool management)
Service Optimization Layer (Orchestration, Federation)
Service Management Layer (catalog, performance, demand, capacity, billing, showback)
Access Management Layer (Identity, Subscriber, Self Service)

What kind of billing or chargeback models do you plan to offer?
What are high level services you are planning to offer (IAAS, DAAS, PAAS, StAAS etc)?

8. Capacity Management Pitfalls What is the size of your Lego?
Overprovisioning Vs Under provisioning • Compute • Storage • Network
© 2014 Citrix. Confidential.20

What is the unit of scale for network, storage and CPU?
Does your unit of scale for resource match workload increase?
What is the percentage reserved for hardware failures?

9. HA and DR assumptionsRetrofitting is next to impossible
HA for Management Infrastructure • Scalable architecture for management nodes, • Ability to scale with scale of infrastructure
HA as a service
DR is not given • DR for management nodes• DR for Infrastructure nodes • DR for User workloads.
© 2014 Citrix. Confidential.22
Introspection Questionnaire
Is HA default or additional service?
What does your cluster look like?
What is the expected boundary for HA?
What is RTO and RPO for your cloud?
Is DR driven by your customer or admin?
Is DR at volume level or network level or vm level ?
Does you DR policy force users to reserve capacity in DR zone?

10. Cloud Security != Traditional Security Security definitions don’t change but the delivery does
Network Security • Perimeter Security • IPS/IDS transformation
Data Security • Data in Motion and Data at Rest• Key Management Issues
