Improvement

Principles provide general rules and guidelines to support the evolution of a

cloud infrastructure. They are enduring, seldom amended, and inform and support the way a cloud fulfills its

mission. They strive to be compelling and aspirational. These principles form the basis on which a cloud infrastructure

is planned, designed and created

Concepts are abstractions or strategies that support the principles and facilitate the composition of a cloud. They are guided by and directly support one or more of the principles.

ideas that have been proven solutions to commonly occurring problems. Patterns are useful for enabling the cloud computing concepts and principles.

Top Ten Private Cloud Architectural Lessons

New World Order – New Ways of Thinking It’s a

best practice!

Gartner says this is the

way!

That’s how we’ve always done it!

Our auditors

said to do it this way!

How Do You Cool Your Datacenter?

Guess what? You’re a Service Provider!

Principle #4

You’ve got competition

Requires service management

maturity

Approach to service

management needs to change

Virtualization is an Enabler – Not a Cloud Solution

Can Reduce Quality of Service

Greater Complexity More Reactive

Requires Right Monitoring

ToolsMTRS Goes Up

A Virtualized Datacenter is not a Private Cloud

Homogeneity Drives Multiple Efficiencies

Simplicity is Elegance

• Drives predictable performance

• Reduces cost of acquisition• Help with predicting time for

new acquisition

Concept #3

“Everything should be made as simple as possible, but not

simpler.”

Redundancy is so 1990s

Redundancy comes with a price

Capital Expense

Operational Expense (power, maintenance)

Stateful applications increase cost

Driven by stateful applications

Concept #2

Is Redundancy Worth the Cost?

Fail Often – Recover Fast!

Software enabled resiliency plans for failure states and focuses on fast service restoration. More failures, but less

total service downtime

Private Cloud

MTRS = Downtime

Fabric Management Enables Resiliency

• Avoid hardware failure

• Redundant at all levels

• Longer MTBF – More Disruption

• Service up 0.99999Redundancy Driven HA

• Goal – minimize service disruption

• Automated fault detection and response

• Fail often – recover fast!

Resiliency Driven HA

Concept #2

Transform Users into Environmentalists

Pay only for what you use

Show the cost of five nines

Elasticity – both up and down

Portable apps enable cost comparison

Principle #9

Is Your Hardware Sick?

Health Model must

provide visibility

into hardware

infrastructure

Pattern #7

More to services than software

Understand hardware

interactions and dependencies

What does “healthy” look

like?

What does “unhealthy” look

like?

What does “failure” look

like?

Detect and respond depend

on understanding

Is it a Headache or a Hemorrhage?

Define both Failure and

Disaster

• How do failures affect the service as a whole?

• Create a dependency tree• Determine when failure becomes

disaster• Detect and automate both failure and

disaster responses

Mechanized• Faster/Predictable

Pattern #5

Standardized increments

Known environmental requirements

Known procurement time

Standardized engineering

* Compute scale unit

* Storage scale unit

Resource DecayPrinciple

#9

Move away from break/fix incident model

Use a pool-based maintenance model

Define % of decay before maintenance

Fault DomainPattern #2 Consider non server component failures

Select the component most likely to fail

How many servers are impacted?

That’s the physical fault domain

Upgrade DomainPattern #3

Host servers still need to be upgraded

All are maintained simultaneously

Workloads migrated away during upgrade

Worst Case Scenario

3% in decay2% in upgrade

10% lost in fault domain15% of total capacity lost

Reserve CapacityPattern #4

Takes advantage of homogeneity

VMs can be relocated predictably

Combines decay/fault/upgrade concepts

Total is Reserve Capacity

RC=[FD+D(max)+UP]/RP

This may be the DR breakpoint
