Parameters of a successful
Public Cloud Deployment
• Application Redundancy
– Critical applications must be able to survive regular provider outages
– Applications should be load balanced across multiple clouds or multiple
availability zones
– The more data-driven the application, the less hyperscale friendly the
application will be
3. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Parameters of a successful
Public Cloud Deployment
• Application Portability
– Ability to pick your ball up and go home
– Applications are not vendor-locked
– Easily decoupled systems
– Legacy app integration
4. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
• Hyperscale development competency
– Outsourcing hyperscale development is a slippery slope
– These are expensive resources onshore
– High short term turnover rate amongst these employees
Parameters of a successful
Public Cloud Deployment

Parameters of a successful
Public Cloud Deployment
• Understanding of at-scale costs
– Costs can ‘hockey-stick’ as workloads increase
– Inefficient operations cost more in the public cloud
6. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
What are the parameters for a successful
Private Cloud Deployment?
• Understanding of growth pattern implications
– Longer term investments (provider contracts, etc.)
– Capacity planning is key
– Requires up-front understanding of existing infrastructure inner workings
7. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
What are the parameters for a successful
Private Cloud Deployment?
• Willingness to grow in ‘chunks’
– Growth happens in larger increments than on public cloud
– Not all resources used all the time
– Larger up front cost than public cloud
8. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
What are the parameters for a successful
Private Cloud Deployment?
• Most like traditional infrastructure
– Choose the right platforms (hypervisor/network/storage) for your
organization
– More flexibility means more decisions to make
9. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
What are the parameters for a successful
hybrid cloud?
• Connectivity between private and public environments
– Extend enterprise network into the public cloud without lowering security
– Understand impact of latency between private environments and public
cloud availability zones
– Capacity plan for a rainy day
10. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
What are the parameters for a successful
hybrid cloud?
• Support of underlying infrastructure and connectivity
– Clear delineation of duties to manage private and public
– Keep internal install base up to date
– Reconcile vendor invoices & understand ‘what you’re paying for’
11. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
What are the parameters for a successful
hybrid cloud?
• Where to put what
– Have a clear vision for which apps will live in the cloud, and which will
stay in traditional infrastructure
– Map apps that will ‘burst’ into the cloud, and understand associated
costs
– Ensure data doesn’t ‘bleed’ between public/private environments
without good reason
12. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Successful Cloud Transitions
• Deciding which applications belong where
– Some workloads lend themselves to being fully virtualized, some don’t
– Remember the 80-20 rule with regard to resource utilization and thereby
cost
– Internal teams ensure no cross pollination exists, or is mitigated
– What are your competitors/friends doing with these apps?
13. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Successful Cloud Transitions
• Ensure the Benefit of the Cloud is realized
– Is it more cost effective?
– Is it more reliable?
– Is it easier?
– Does it scale better?
– Can somebody else operate it?
14. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Successful Cloud Transitions
• Make your move successful with a strategic approach
– The whole team needs to sign off, from C-Suite to IT Johnny
– Evaluate the options through a holistic lens (Technical, Financial,
Strategic, Human Capital, etc.)
– Your plans must be fluid; ready to change with the weather
15. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Successful Cloud Transitions
• Evaluate each application
– Develop internal ‘tiering’ system for apps
• Tier0 – 15 minute recovery time
– Critical systems – spend your money here
• Tier1 – 1-4 hour recovery time
– Email, non-revenue generating systems
• Tier2 – 4-8 hour recovery time
– Support systems and the like
• Tier3 and beyond
– Everything else
16. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Successful Cloud Transitions
• Regulatory Compliance Considerations
– HIPAA/PII/PHI – Not public cloud friendly
• This market is emerging, expect it to be expensive and risky in the
short term
– PCI
• Moderate public cloud complexity
• Cost is a consideration here as well
• Short list of providers have gone through the validation process
17. ServerCentral | 111 W . Jackson Blvd., Suite 1600 Chicago, IL 60604 | +1 312.829.1111 | www.servercentral.com
Recent Experience

Healthcare SaaS Continued
• Selected Private Cloud, Disaster Recovery as a service (DRaaS)
• Primary site is Highly Available, secondary is non-HA
• Secondary site supports only Tier 0,1 apps
• Secondary site is also backup target for long term archival
• Management up to the application (OS management included, Customer
manages applications)

So lets look at a typical rack quickly and see if we can find the hidden costs.
