Current state of affairs

It’s a bit of a mess !

IT Pro perceptions of what qualifies as ‘cloud’Emphasis on hosted services, not technologyPhysical elasticity of services is key

Scale capacity up and down based on demandNumber of users up and down at willAdd and remove features and functionality at willMulti-tenancy architecture important for software services

Commercial flexibility of services is keyPay for what you use; changes quickly reflected in billing Can stop using service at any time without penalty

Variation in emphasis on IaaS, PaaS and SaaS

“How do we make the move to the cloud?”

Putting the cart before the horseCloud is not an end, it is a means to an endAnd it is not the only means!

The stars aligning?

It’s really about ….

Back to basics

ObjectivesReduced cost and riskImproved service levelsReduced burden on IT

Key considerationsWorkload characteristicsIntegration requirementsSecurity and complianceOperational requirements

Horses for courses

Different applications and workloads will naturally run in different places

Hybrid and overspill requirement exist.

Bottom line: It doesn’t make to sense to force-fit everything to a single deployment model

SaaS Suitability Quadrant (Large Scale Requirements)

The suitability of ‘software as a service’ depends on the context

Costs, risks and constraints can easily arise

Already using SaaS in this context

Consider SaaS suitable in theory

Consider SaaS to be unsuitable

IT Management Survey, 2008, 202 UK respondents

Use of SaaS, to any degree in any context(Picture derived from detailed responses of 202 IT managers to a range of specific questions relating to if and how SaaS is used)

0% 20% 40% 60% 80% 100%

Organisations in which IT is regarded as asource of business advantage by senior

business management

Organisations in which senior businessmanagement regard IT as primarily just an

enabler of advantage

Organisations in which the IT department islargely viewed as a cost centre at senior

business management level

Use SaaS at least somewhere in the organisation

No use of SaaS anywhere in the organisation

Don't know (unable to answer SaaS related questions)

Lots of hosted service options, lots of potentialON-DEMAND SERVICE CATEGORIES

Business application services It is in this area that the term ‘Software as a Service’ (SaaS) was originally coined. Services at this level are typically focused on the delivery of complete business functionality, e.g. CRM, ERP, etc.

Hosted productivity tools Services here are more concerned with horizontal capability ranging from desktop suites for end users, through to modelling, development and project management tools for analysts and developers.

Hosted comms/collaboration Spearheaded initially by hosted email and web conferencing, the number of services offerings in this area has exploded to include full unified communications and/or social media (directories, blogs, wikis, etc).

Trading community services As supply chain automation has gathered momentum in some industry sectors, services have emerged aimed at facilitating the way in which customers and suppliers collaborate and transact electronically.

Plug-in services A myriad of services exist which do not provide complete business functionality but ‘plug into’ existing applications to enhance or extend them. Examples include everything from mapping to credit checking.

Application platform services As an alternative to consuming pre-built services from external providers, application platform services provide development and runtime environments allowing custom applications to be built and hosted online.

Operational services This often overlooked but highly important category is where we find services concerned with online backup, archiving, security (e.g. email filtering), etc., and even full blown monitoring and management tools.

SaaS due diligence Provider

Stability, maturity, culture, etc Resources, facilities and policies

Service Software foundation, e.g. ‘standard’ package versus home grown Interoperability provided out of the box, e.g. desktop tools, mobile, etc Ability to configure, customise, extend, integrate (standard vs proprietary) Scope: not just functionality, but backup, recovery, archiving, support, etc Administration, operation, provisioning, security (including who does what) Data storage, management, import, export, auditing, compliance, etc End of life, inc migration of process definitions /business rules as well as data

Commercial Contract terms TCO, lifetime costs

Tips from ‘Cloud for Dummies’ Don’t dismiss or try to avoid cloud

It isn’t a massive revolution, but there is some good stuff going on

Beware of sweeping generalisations Cloud can mean all kinds of things, and no one size fits all Context is everything, know your own requirements

Don’t get suckered into industry/supplier agendas Everything is not moving to ‘the cloud’, and won’t do in our lifetimes Think cloud as part of the answer rather than the only answer Use your own requirements and objectives as the point of reference

Don’t make assumptions Work through the logic and the numbers yourself Do your due diligence – cloud does not magic all problems away

Focus on the underlying trend towards service-centricity
