“Enough with the cloud-washing! What’s for real in the cloud?”


Definition: cloud computing

► A standardized IT capability (services, software, or infrastructure) delivered via the Internet in a pay-per-use, self-service way


Three layers of cloud computing

Software as a Service (SaaS)Finished applications that you rent and customize

Platform as a Service (PaaS)Developer platform that abstracts the infrastructure, OS and

middleware to drive developer productivity

Infrastructure as a Service (IaaS)Deployment platform that abstracts the infrastructure


Enterprises cite flexibility and on demand over cost reasons


Three types of IaaS cloud platforms

Source: See the April 2009 “Which Cloud Computing Platform Is Right For You?” report.


The first customers of cloud are not typical IT ops• Startups — developers using Web at scale

– Web-based business, SaaS, collaboration services, widget providers, mobile services, and social networking

• Small businesses — using SaaS – Online businesses, online presence, collaboration, and enterprise

integration

• Enterprises — developers and one-off projects– R&D projects, quick promotions, widgets, online collaboration,

partner integration, social networking, and new business ventures

• Firms — with compute intensive tasks– Overnight ad placement or transportation calculations


Development is ahead if IT ops on adoption


Security and maturity top list of concerns for IaaS cloud services


Cloud use trends

• Web hosting — leveraging IaaS, PaaS elasticity to lower costs, accommodate spikiness

– Application hosting — beyond Web pages; match the service consumption to the revenue line.

• Test and development — function and scalability testing, some QA

• HPC/technical computing — grid-based and similar workloads that need temporary scale

• Collaborative computing — collaborative access to shared services, repositories, massive data sets

– B2B, internal, shared service, commercial info services


What fits best

Best use: temporary capacity, elastic capacity

• Web sites — three-tier architectures with minimal DB tiers.

• SOA applications — with loose coupling of Web services; scale via load balancing and app-level caching.

• Highly parallelized workloads — HPC w/o close coupling; grids, Hadoop

• Applications that fit within a single VM — can be any type of self-contained x86 application


Early cloud examples• Indy500.com — streams live race

footage and statistics

• Wendy’s — Short-term, interactive promotional site for $0.99 menu.

• USA.gov — Govt. information web site elastically scales

• NASDAQ — Market Replay service

• US Army — Testing troop vulnerability application on cloud platform

• Eli Lilly — drug research

• Harvard Medical School — developing genetic testing models

Sources: www.NASDAQ.com, www.espnfanzone.com, Indy500.com


What doesn’t fit in IaaS clouds today?

• Anything subject to compliancy

– Wait for best practices to evolve.

– Includes PCI-compliant applications

• Anything performance sensitive (other than Web)

• Apps that call back to performance sensitive services in your data center

• Apps that require tight coupling between instances

– Sensitive clusters — Oracle RAC

• Large applications — that don’t fit inside VMs


A game plan to consider

The next 90 daysThe next 90 days

• Start experimenting with public cloud platforms.

• Endorse one or two public clouds and craft a “work-in-progress” policy for cloud use.

• Start with non-critical applications, and move up the stack as you gain experience


Longer termLonger term

• Start evolving towards an internal cloud

• Shift to Strategic Right-Sourcing


Applications to start with

• Test and development

– Functional and performance testing

– But choose Web-, VM-ready applications.

• Temporary and/or volatile Web sites

– Marketing, collaboration sites are easiest

– Take responsibility for security yourself.

• Grid-class technical/HPC projects

– Loosely coupled applications work best

– Anonymize any customer/sensitive data.


Then: Move to Strategic Right-Sourcing

• Segment your IT portfolio into:– Key services that drive profitability, efficiency of the business.

– Services that are undifferentiated but unique to the business.

– Commodity services.

• Identify outsource options for commodity services.

– SaaS, ASP, Cloud services, MSP, traditional outsource, etc.

• Build in-house expertise in outsource contract management.

• Incorporate right-sourcing into enterprise architecture.

Agenda

• The Benefits of Cloud Infrastructure

• Cloud Types – Current and Future

• Sample Cloud Use-Cases

• Cloud Deployment and Performance


Cloud ComputingWhen Is It a Good Fit for the Enterprise?

• Applications and processes have highly variable demand

• Internal data center capacity limits are being reached

• Hardware is at the end of its serviceable life

• Speed of provisioning is constraining business execution

• Your data center no longer offers a competitive advantage to the organization– No longer provides a differentiation

– Competitors’ time to market surpasses yours

• In-house application development

Don’t Forget Performance - The Connection between Cloud and User Experience

• Your applications are in the cloud / your end-users are not

• Not all clouds are equal – QoS in the Cloud will play a vital role to ensuring end-user experience

• And performance, including end-user connectivity, needs to be monitored to fully benefit from cloud deployment capabilities

Your Cloud

Cloud Computing Realities: Getting Past the Hype And Setting Your Cloud Strategy

Imad Mouline, CTO, Gomez

Not all clouds are created equal

Performance variations exist across geographiesAverage response time and availability are almost equal

5x variation in response times across key markets

How does this inconsistency impact end-user behavior?

The promise of elasticity

Traditional Capacity Requirement

Ideal Cloud Capacity Throttling Capability

The promise of flexibility

No revenue coming in… Why Pay?

Weekend lulls… Why Pay?

The challenge of a shared infrastructure

What does your ‘neighbors’ traffic look like?

For applications with shared infrastructures, end-user performance is the best measure of overall system health

Best Practice – Define your goals and build a plan

Align goals across your organization Why are we moving to the cloud?

Common goals include:

1.Additional Capacity – How much capacity do we need during normal and peak times?

2.Improved End-User Experience – What performance goals are we trying to deliver against?

3.Greater Elasticity – How quickly can the provider we select ramp up to meet our needs?

4.Flexible Bursting – How fast do we need to be able to access additional capacity?

If only there was a button to push!

Best Practice – Keep your end-users in mind

Geographic disparities

4 sec’s

22 sec’s

How was that experience for your customers?

Test your cloud applications the same way your customers use it:

What they do? Customers care about completing tasks NOT

whether the homepage is available

Where they do it from? Your customers don’t live in the cloud, test from their perspective

When they do it? Test at peak and normal traffic levels, to find all the problems

What expectations do customers have? Is 4 seconds fast enough or does it have to be quicker?

Find configuration, capacity, and performance problems before end-users do with pre-production testing and production monitoring

Best Practice – Performance testing cloud capabilities

Evaluate vendors based on your goals…

CapacityTest vendors to 15-20% above estimated capacity goals

ElasticityBaseline end-user performance before, during & after testing

Test configuration settings explicitly

Ramp elasticity testing to peak levels

BurstabilityIsolate the cloud elements from other infrastructure to test

Test the “failover process”

Best Practice – Set SLAs & objectives to match your needs

Set SLAs based on your goals…

End-user availability and response times

Capacity & elasticity objectives

Burstability goals

Set SLAs based on how you are using the cloud…SaaS PaaS IaaS

• Transactional Success Rate• Fast end-user experience across key geographies

• Availability and performance of key components, services, and API’s

• Hardware & OS availability / performance• Network connectivity

• Capacity and elasticity requirements• Consistency across key markets
