Cloud service models for executives

Service model choices are driven by the consuming organization's employee skill set. For example, system administrators manage infrastructure. If IaaS is the chosen service model, the enterprise will need to maintain and grow this group's knowledge and capabilities. Because the base infrastructure gets consumed as a service, administrators can refocus on new career growth opportunities beneficial to the enterprise in the longer term. An example might include learning infrastructure scripting skills with languages such as Chef and Puppet:

Heavy software development shops may choose to consume PaaS services. The platform carries all of the components, frameworks, drivers, pieces, and parts, enabling developers to be productive immediately. There are many different types of platforms for building many different things. Software development is not the only choice or industry with PaaS available, but it is the most prevalent. As an example, in-house developers need to be comfortable with the platform chosen. If Java is their forte, a Microsoft Azure PaaS service may be slow in the adoption of new Java capabilities. Teams may need additional and ongoing training depending on the platform chosen. Additional investment may outweigh the benefits if the platform is too much of a mismatch to current skill sets or lacking capabilities for strategies chosen.

There are opportunities where no infrastructure is needed separately. The software is prebuilt with all the features and functions needed already included for a fee. Licensing is consumed per some unit, usually per enterprise or per user. The SaaS model is rapid to deploy with rapid adoption rates. SaaS does not have an answer for everything, but very helpful when solutions are available.
