Session Summary

Citrix Products/Services discussed– Citrix Cloud Consulting – Citrix CloudPlatform, CloudPortal Business Manager

Key Takeaways– The main reasons for cloud implementations failures – Session will go over some of these reasons in great detail and provide ways to

avoid those.


Service Providers | Telcos

Web 2.0

Enterprise | Education | Government

250+ Large Scale

Production CloudsIn Deployment

Production siteswith over

40,000+Servers


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

Use this box as a guideline for proper image placement. Place your image on top and align to box.



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

IAAS (Compute, Network, Storage)

Cloud-Era Apps



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

cluster

cluster

Isolated networks

Shared Storage

Isolated networks



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



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



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 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?


8. Capacity Management Pitfalls What is the size of your Lego?

Overprovisioning Vs Under provisioning • Compute • Storage • Network



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?

What is the ratio between primary and secondary storage?

What is the average size of your vm?


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.



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

System Security • A/V updates and policies

Do you plan to enforce corporate security standards and how?

Do you allow your users to have their own security policies and products?

What are the compliance standards your apps or end users need to meet?

How often do you need to generate security reports and to whom?

What are security protections you provide to your user by default?
