Cloud IaaS: Who is the buyer?

Source: Gartner, Market Trends - How Customers Purchase Cloud Iaas (Lydia Leong), January 2013

Data center infrastructure assets, as well as outsourced services such as hosting, have traditionally been purchased by a business’s IT operations – often in conjunction with a procurement organization.

Cloud IaaS has a different buyer and procurement cycle. Business leadership, not IT, often controls the budget.

Part of a broader shift in IT procurement

patterns:

Responsibility increasingly shared by the business and IT

Budget increasingly comes from the business

Developers are leading the foray into cloud

• Rather than Central IT, it will be business-unit-aligned developers (the new “cloud admin”) who will lead the company into the cloud

• Business looks to developers to drive a solution rather than I&O

• Developers start with solutions that are designed to integrate with public cloud first and the enterprise second

• Developers are the face of business buyers

• This is not unsanctioned adoption; the IT ops team might actively be opposed to it, but this use is sanctioned by the business and paid for by the business

11 Global Marketing

Typical enterprise cloud adoption cycle

1. An individual technical user, often a developer gets a cloud IaaS for a project – usually one which must be completed on a tight schedule

2. This ad hoc adoption grows organically, project by project and person by person

3. A company becomes aware that it has multiple projects running on cloud IaaS and decides it needs better governance

4. Enterprise arch team tasked with • writing cloud IaaS adoption policy

• setting the governance rules

• evaluating providers (usually in cooperation with IT ops)

• signing MSA’s with one or more IaaS providers

5. IT projects are able to adopt any approved IaaS providers at their own discretion

6. IT ops may decide to adopt a workload migration strategy, shifting some new and existing workloads onto cloud IaaS

What does this mean for IT?

IT response #1

• Very different workloads

• Virtualized applications are traditional in design: don’t scale out, aren’t componentized web services, tend to have a fixed and permanent footprint

• Cloud applications are elastic or transient: designed to scale out, componentized in construction, intercommunicate via web services, designed to fail

Source: Forrester Research, Inc. - The Rise Of The New Cloud Admin (James Staten, Lauren E Nelson), February 2013

Build on top of existing virtualization (wrong)

14 Global Marketing

IT response #2

• Not a way of keeping the business from the public cloud

• Private clouds are an extension of the public cloud not vice versa

• The public cloud development team is buyer and driver of requirements and user experience for private clouds

• To be a private cloud it must – provide self-service access to developers

– be fully standardized and automated

– have a pay-per-use model or another mechanism for incenting developers to not park workloads there forever

Build a private cloud (maybe wrong)

DevOps in development

Done means released Code deploy not code complete

Infrastructure as code Configuration is code and needs control

Frequent releases Self service / continuous delivery

Version control everything Everything is an artifact (scripts, xml, source)

Instrument operations Feature flags / canary releases / immune systems

Test end-to-end Test driven code and infrastructure

25 Global Marketing

DevOps in operations

If anything fails stop the line Reduce technical debt early

Instrument pervasively Collect data to detect trends early

Enable graceful degradation Some availability is better than none

If it’s hard do it more often Practice makes perfect

MTTR vs. MTBF Re-provision not repair It’s easier to recover to a known state

Automate where possible Desired state consistency
