When it comes to delivering a cloud deployment there is a spectrum of deployment options available for you to choose from. The most common and written about is the public cloud option like Amazon Elastic Compute Cloud (EC2), or Google Apps. These cloud deployments allow any user with a credit card to gain access to the resources. To a private cloud deployment where all the resources are owned, managed and controlled by the enterprise. To gradations in between from third party managed, to third party hosted, to a very common emerging model called “shared cloud services” or “member cloud services.” Here you must be a member to access the services, and they can be made available to you typically in a shared resources option or a dedicated resources option, depending on your needs and configurations. Finally you can merge the options between public and private and create what has been coined a “hybrid cloud”. When it comes to deciding which cloud delivery option you want to choose it needs to tailored to the business, the time and money requirements, and the availability of the resources. There is a spectrum of delivery options, and there is no single right way. Private Implemented on client premises Client runs/ manages Managed private cloud Third-party operated Enterprise owned Mission critical Packaged applications High compliancy Hosted private cloud Internal network Third-party owned and operated Standardization Centralization Security Internal network Mix of shared and dedicated resources Shared Cloud Services Shared facility and staff Virtual private network (VPN) access Subscription or membership based Shared resources Public Cloud Elastic scaling Pay as you go Public Internet A Hybrid cloud solution is some mix of private and public integrated with your traditional IT to deliver the cloud solution to the end user and can involve any of the public to private options.
We also asked our panel of 1,090 what factors would keep them from using a public cloud service. Respondents could select multiple items and were asked to rank factors of a scale of 1 to 5, where &quot;1&quot; means &quot;Not a Significant Barrier&quot; and &quot;5&quot; means “A Very Significant Barrier.&quot; Concerns about security and privacy of company data represent the most significant barrier to public cloud services. Concerns about service quality – both the computing services and responsiveness of delivery over the Internet – also ranked high, as did doubts about the promises of cost savings.
On-demand self-service: you choose what you need, when you need it Ubiquitous network access: using Internet virtual private network (VPN) or dedicated network connection Location-independent resource pooling: no need for in-house or specialized staff; leverage IBM expertise via global data centers Rapid elasticity: massively scalable with rapid provisioning Pay per use: usage-based billing model: you only pay for what you use or reserve
So how are real customer situations realizing benefits from the cloud. We’ve compiled here a list of the ways that customers are telling us they’ve been able to see real, tangilbe results form their cloud delivered implementations. Why can a cloud environment have this kind of effect? The key is that the cloud is based on three essential fundamentals: It’s standardized, it’s virtualized and it’s automated. That’s how you can provide scalable services. That’s the way you’re going to see efficiency. And that’s the way you’re going to drive down costs and improve service. That’s really a pretty simple equation, and we are seeing clients that are doing this achieve very real, measurable business results. For example: Virtualization of IT resources —servers, storage, networks and applications—are pooled and virtualized to help provide an implementation-independent, efficient infrastructure with elastic scaling , meaning the environments can scale up and down by large factors as demand changes. Automation through a self-service portal and automated provisioning Standardization of pricing, processes and services The results shown here are indicative of typical results of IBM cloud clients, based on our client experiences and our own internal results.

So far, clients significantly prefer private clouds over public clouds 64% 30% Public 38% Hybrid Private "Very appealing" or "appealing" Source: IBM Market Insights, Cloud Computing Research , <ul><li>The companies that did show of preference for public cloud in our study display certain common characteristics. They are: </li></ul><ul><ul><li>More likely to be using a provider for traditional outsourcing of infrastructure and/or business processes </li></ul></ul><ul><ul><li>Less likely to view loss of control over IT resources as an obstacle to acquiring Public Cloud </li></ul></ul><ul><ul><li>More likely to view application/database, availability, and incident/problem management as critical processes for their business </li></ul></ul>
Concerns about data security and privacy are the primary barriers to public cloud adoption Percent rating the factor as a significant barrier (4 or 5) Respondents could select multiple items 69% 54% 53% 52% 47% Security/privacy of company data Service quality/performance Doubts about true cost savings Insufficient responsiveness over network Difficulty integrating with in-house IT What, if anything, do you perceive as actual or potential barriers to acquiring public cloud services?
