The Public Cloudscape

Enterprise public cloud services can be segmented into infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS) and software-as-a-service (SaaS). In a wider context, IaaS, PaaS and SaaS are being supported by digital infrastructure layers and sold either direct or through cloud channels. The picture below provides a value chain view of what we call the Public Cloudscape:

The Public Cloudscape

This Public Cloud value chain is segmented into an infrastructure and a services layer. The infrastructure layer provides core connectivity (carriers such as KPN and Eurofiber but also the AMS-IX), data center services (providers such as InterXion, OCOM and Switch to name a few), hosting providers (Argeweb, Cyso, True, etc.) and PaaS and IaaS providers (check out our Dutch Public Cloudscape for the top Dutch providers in this space). PaaS can be subdivided into software development as-a-service, database as-a-service and middleware (for instance integration) as –a-service. IaaS can be subdivided into compute, store and backup as-a-service.

On top of the infrastructure layer resides the SaaS layer. The most popular SaaS solutions are CRM, HRM, BI, ERP, SCM, Collaboration, Communications, Workspace, Office productivity, Finance, Marketing analytics, Demand generation, Project management, Retail & eCommerce, Document management and Enterprise social media, but there is also a slew of industry specific SaaS solutions. (check out our Dutch Public Cloudscape for the top Dutch providers in the SaaS space).

Last but not least, cloud channels such as affiliates, aggregators, appstores, brokers and exchanges distribute and resell PaaS, IaaS, and SaaS solutions. Dutch examples include KPN, Copaco and Portland for instance.
