Accelerate Business Agility with PaaS

David S. LinthicumAnd

Chris Haddad

Most application development shops can not create business solutions in a timely manner.

Thus, many clouds are not meeting expectations.

Business agility is still elusive.

The results:

Application backlogs

Missed business opportunities

Increase in complexity

Increase in latency

Lack of elasticity

Lagging time-to-market

Lack of business agility

Hitting the Wall

The Market is Speaking for Itself

The Growth of PaaS is Driven by the Need for Business Agility

“Research firm Gartner predicts that worldwide platform as a service (PaaS) is set to reach a high of $1.2 billion in 2012, as compared to $900 million in 2011.

Market revenue is expected to increase as the years come with a total of $1.5 billion in 2013, and growing to $2.9 billion in 2016, according to the Gartner report entitled, ‘Market Trends: Platform as Service, Worldwide, 2012-2016, 2H12 Update.’”

The Drive to Serve the End Users

• Large segments within the PaaS market include:– Cloud application platform services (aPaaS),

accounting for 34.4 percent of total PaaS spending in 2012.

– Cloud application life cycle management (ALM) services (almPaaS) at 12 percent.

– Cloud BPM platform services (bpmPaaS) at 11.6 percent.

– Cloud integration services (iPaaS) at 11.4 percent.

The Operational Benefits Are Obvious

Business Agility is the Objective

• Cloud-based roles and org• Workload centric resource models

(e.g., e-mail)• Co-sourced staff

• Automation & self service• Consumption-based charge-back

models• Mature service framework to

manage service-centric model

• Pervasive virtualization• Converged architecture• Federated workloads• Pools of resources

Readiness: People, Process & TechnologyAchieving the end-state requires significant transformation

Enterprise IT Cloud

TECHNOLOGY

• Complex• Expensive• Inflexible• Siloed

PROCESS

• Little infrastructure automation• Services allocated to LOB or

application owner• ITIL-based services frameworks

loosely applied

PEOPLE

Organizational silos of • Infrastructure (compute, storage,

network)• Application & management• Security

Achieving Agility Through DevOps

Operations

Develop Test Stage Deploy OperateDesign

• Good– Budget - It’s cheap.

– Power - It scales.

– Development – It’s productive.

• Bad– Limitations - Can only use what’s there.

– Standards - Few exist.

PaaS in the Real World

• Make sure to consider the target application.

– Static application requirements often lead to PaaS not being a fit.

• Make sure to consider resources required.

– PaaS clouds limit use of resources, or they become too expensive quickly.

• Make sure to consider data persistence.

– Data support varies greatly.

• Make sure not to get religious around the languages.

– “We’ll do it in any language as long as it’s Python.”

• Make sure to consider leveraging the outside world.

– Need to interact with other clouds, and on-premise systems.

• Make sure to consider staging and testing.

Real World Advice

• Start with the data, and work up to the services and UI. Not matter what the PaaS provider suggests.

• Create an initial POC, and make sure to validate the complete stack.

• Define a staging and testing strategy before you begin development.

• Consider SOA approaches in the design and deployment of the PaaS-based application.

• Make sure to do load testing along with functional testing.

• Make sure to model performance.

• Don’t fall in love with a PaaS player. You may need to use several.

Architecture RoadmapGeneral Guidance

Build a solid foundation:

Determine business drivers

Understand: data, services, business processes and system integration points

Design a “cloud-friendly” enterprise architecture roadmap that leverages Services Oriented Architecture (SOA)

Determine an integration strategy for internal and external systems

Outline a migration path for legacy systems to the new architecture

“as-is”

“to be”

deploy

How do you measure business agility acceleration?

A few benchmark business metrics– Time between business opportunity idea and business execution– Time to on-board a new partner, supplier, distributor, customer– Setup time before entering a new market, unveiling a new

campaign, delivering a new product– Time between business change request and deployment

A few benchmark technical metrics– Time to create project workspace– Time to build, integrate, test– Time to approve, promote– Time to deploy, release– Dwell time – time waiting for the next operation to commence or
