Before making an informed decision, you must be informed. Ask yourself the following before beginning a relationship with a Cloud Provider.


 


 

Internally:
  1. What are your strengths and what is strategic?
  2. What is the appetite? What is the process surrounding organization moving systems, data, processes, into the Cloud?
  3. What data is governed by compliance regulatory requirements? Not everything in IT is subject to regulation.
  4. What does your cost structure look like?
  5. Can IT become a contributor to the frontline if resources are deployed more effectively?

Externally: 
  1. How mature is the provider in providing services?
  2. What is your exit strategy in case the relationship goes south?
  3. SLA’s are a source of strife when you don’t trust your provider?
  4. What are the scale boundaries for the services proposed, how big can they go?
  5. How would you use a multi-vendor strategy for the cloud? How well do the providers work together? How much will your architecture have to change to accommodate this methodology?
  6. Review the provider Disaster Recovery Plan and ask to see the latest test?
  7. How easy is it to extend the solution? Is this something that I can do myself or will I have to pay the provider to make extensions?
  8. Does the provider have an App Exchange that will let extensions be added easily?
  9. Ask to see future release schedule and how often they are done?
  10. How often does the provider take the Cloud Solution down for maintenance?
  11. Who are the implementation partners?
  12. Does the platform scale?
  13. Understand the difference in the big three: SaaS, IaaS, PaaS.

Let us help:

Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. Meanwhile, broadband service has become increasingly available to support user access from more areas around the world.

SaaS is closely related to the ASP (application service provider) and on demand computing software delivery models. IDC identifies two slightly different delivery models for SaaS. The hosted application management (hosted AM) model is similar to ASP: a provider hosts commercially available software for customers and delivers it over the Web. In the software on demand model, the provider gives customers network-based access to a single copy of an application created specifically for SaaS distribution.


Benefits of the SaaS model include:
  • Easier administration
  • Automatic updates and patch management
  • Compatibility: All users will have the same version of software.
  • Easier collaboration, for the same reason
  • Global accessibility.

The traditional model of software distribution, in which software is purchased for and installed on personal computers, is sometimes referred to as software as a product.

Infrastructure as a Service is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis.


Characteristics and components of IaaS include:
  • Utility computing service and billing model.
  • Automation of administrative tasks.
  • Dynamic scaling.
  • Desktop virtualization.
  • Policy-based services.
  • Internet connectivity.

Platform as a Service (PaaS) is a way to rent hardware, operating systems, storage and network capacity over the Internet. The service delivery model allows the customer to rent virtualized servers and associated services for running existing applications or developing and testing new ones.

Platform as a Service (PaaS) is an outgrowth of Software as a Service (SaaS), a software distribution model in which hosted software applications are made available to customers over the Internet. PaaS has several advantages for developers. With PaaS, operating system features can be changed and upgraded frequently. Geographically distributed development teams can work together on software development projects. Services can be obtained from diverse sources that cross international boundaries. Initial and ongoing costs can be reduced by the use of infrastructure services from a single vendor rather than maintaining multiple hardware facilities that often perform duplicate functions or suffer from incompatibility problems. Overall expenses can also be minimized by unification of programming development efforts.

On the downside, PaaS involves some risk of "lock-in" if offerings require proprietary service interfaces or development languages. Another potential pitfall is that the flexibility of offerings may not meet the needs of some users whose requirements rapidly evolve.


Bonus -  

XaaS is a collective term said to stand for a number of things including "X as a service," "anything as a service" or "everything as a service." The acronym refers to an increasing number of services that are delivered over the Internet rather than provided locally or on-site. XaaS is the essence of cloud computing.

 The most common examples of XaaS are Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). The combined use of these three is sometimes referred to as the SPI model (SaaS, PaaS, IaaS). Other examples of XaaS include storage as a service (SaaS), communications as a service (CaaS), network as a service (NaaS) and monitoring as a service (MaaS).
