This document discusses reasons why cloud projects fail and provides ways to avoid failures. The main reasons discussed are having the wrong reasons and team for pursuing cloud, lacking a product manager, underestimating how applications impact the cloud, viewing cloud as just expanded server virtualization, cloud operations differing from traditional IT operations, platform limitations, cloud requiring multiple technologies, capacity management pitfalls, overlooking high availability and disaster recovery needs, and traditional security models not applying to cloud. Introspection questionnaires are provided to help assess weaknesses. The document encourages attending additional cloud sessions.

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 Team
Vetting 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

6. © 2014 Citrix. Confidential.6
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?

7. © 2014 Citrix. Confidential.7
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

8. © 2014 Citrix. Confidential.8
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

3. It’s the App, stupid…
Easy to underestimate the complexity of apps and its impact on cloud
Templates
VR Virtual Private
Gateway

Cloud-Era Apps

10. © 2014 Citrix. Confidential.10
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?

4. Cloud != Server Virtualization++
Cloud is not a next version of virtualization projects
Common Network
Local Storage
Accounts
Accounts

Shared
Storage
Isolated networks

12. © 2014 Citrix. Confidential.12
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 Operation
Operations Reinvented
Backup/Recovery
Monitoring
Performance &
Patch
Management
Multi
Tenancy
Usage
Metering
SLAs
per
Account

14. © 2014 Citrix. Confidential.14
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

16. © 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?

17. © 2014 Citrix. Confidential.17
7. Cloud is not a single product
Incorrect 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)
Operations
(backup/monitoring/Security)
ExternalManagement
Adaptors(Incident,release)

18. © 2014 Citrix. Confidential.18
Introspection Questionnaire
What is your user onboarding process?
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)?
How does your user interact with you when there is an issue?

19. © 2014 Citrix. Confidential.19
8. Capacity Management Pitfalls
What is the size of your Lego?
Overprovisioning Vs Under provisioning
• Compute
• Storage
• Network

What is the percentage reserved for hardware failures?
What is the ratio between primary and secondary storage?
What is the average size of your vm?

21. © 2014 Citrix. Confidential.21
9. HA and DR assumptions
Retrofitting 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.

22. © 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?

Network Security
• Perimeter Security
• IPS/IDS transformation
Data Security
• Data in Motion and Data at Rest
• Key Management Issues
System Security
• A/V updates and policies
Compliance
Security
as a
Service
Multi
Tenancy
Usage
Metering
SLAs per
Account
