Cloud software will grow by 48% (€1.7bn) to $5.3bn.


In 2010, cloud software growth was more than 80% of the overall growth but this was due to the very low on-premises software growth. Despite a decline in relative market growth for cloud software, this will still be an outstanding result

Software-as-


a-Service (SaaS) and Platform-as-a- Service (PaaS) higher up the stack. That is where tomorrow’s leaders will find real differentiation. Hybrid clouds – ie, SaaS and PaaS, in combination with internal applications – will help organizations accomplish tasks they cannot accomplish today and will cement IT’s role as a driver of business growth.


When SaaS also provides a platform it makes it easier to customize and tap into an


expanding ecosystem of third-party


applications. Service providers will begin to provide targeted vertical solutions.


CLOUD COMPUTING CREATES VALUE


The current focus on infrastructure doesn’t help organizations differentiate themselves. Together, SaaS and PaaS rather than IaaS will enable IT to create value through a combination of cost reduction,

“Cloud computing will become ubiquitous. Private clouds accommodate a desire, and often a legal requirement, for data to remain within an enterprise. Public clouds meet the needs of many enterprises, and we can expect to see more ‘hybrid’ cloud models. IT pros will have to manage a portfolio of models that include traditional and virtualized cloud as well.”

licenses are not just about initial purchase price. On-going support and maintenance (to get upgrades) are the hidden costs, plus cost of upgrade (the latter is seamless in SaaS), so you don’t have to build an in-house team to support the application and get guaranteed service levels.

Before the full potential of cloud computing can be realized, companies and their service providers have plenty of technical and business hurdles


to and managing federated


As data and services are spread across a variety of service providers, hybrid models will provide the best balance of flexibility while managing risk.


We expect the shift to move from the cost of discrete IT components to a discussion about the total cost of ownership (TCO) of cloud solutions. The current emphasis is on economies of scale from volume, automation, commoditization and consolidation.


There are many implicit cost elements

overcome. Technologically, IT teams will have to develop strategies for implementing


identities, which are necessary for enabling consistent permissions, roles and traceability across multiple service providers. IT leaders will have to work with cloud service providers to determine the right federation rules for their communities.


WHAT CONCERNS YOU? Concerns for providers include: platform- level version management activities


(the


ability to manage local patches, versioning and upgrades without introducing risk to cloud consumers); and richer application programming interfaces (APIs), which are necessary


for more sophisticated applications.


Concerns for users involve: consistent policy enforcement across cloud providers; access to event meta-data, which is critical for analytics; governance over applications and data that is stored in third-party data centers; better fault- tolerance for application architectures; and network latency. n
