Citrix Synergy 2014 - Syn231 Why cloud projects fail
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.

Editor's Notes
- #4 Here is a quick look at a few of the customers who are running Citrix cloud offerings today in their environment, BT and TaTa on the public cloud front, Spotify and Edmunds.com are some of our web 2.0s and we’ve seen a lot of growth in the enterprise and education market over the last year with the likes of Nokia and Autodesk.
- #6 CapExand OpEx
- #10 ----- Meeting Notes (4/23/14 11:23) -----Its the app, stupid... change text to black in the second What to do slide? Building and Maintaining Application CatalogTemplate Management requires automation Impact on licensing management Underestimating the complexity and weight of legacy applications
- #12 User Onboarding & Application OnboardingIAM, Workload migration Accounts, Resource limits Mapping between Organization Roles and Domains Resource Limits. Application Blue Prints VPC, Cloud Formation Isolation Models Network models (security groups, VLAN) Services definitions Network New Storage Models Elastic Block Storage ----- Meeting Notes (4/23/14 11:23) -----Too much text again..
- #18 Bringing cloud up involves multiple software layersIntegrations can be quite complex and impede speed of innovation
- #20 Determination of unit of scale is critical Is unit of scale Host/POD/Cluster? Balance of CPU/RAM/Storage Network can become bottleneck
- #21 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?
- #26 The key points here are the CSA is the discovery process for cloud. The CSA is driven by exchange of information. CSA is most effective with lots of information exchange between citrix and the client.Opportunity phase (discovery) includes the Business case processIn Business Case process Customers will take the CSA output and generate Business Case/justifications for moving forward with cloudAnalysis phase (Cloud Offerings definition) customers decide on key features that make it into the initial cloud offerings and those that will be released over the various phases. Customers typically conduct a POC or CCP/CPBM Assessments during the Analysis phase.Design phase (Infrastructure, Support, logistics definition) customer gets specific on the design choices determined by the service description. The Cloud Architecture is a key document in the design phase.Implementation phase (CS/CPBM installation/customizations) customer deploy the cloud orchestration and management software. CCP Implementation services get the customer running quicklyRollout phase (Cloud Offering in commercial Market) customer goes live with the Cloud offering and end user subscribers start using the services.
