Cloud Service Categories
SaaS (Software as a Service) is the most popular type. Examples include Salesforce, Google Apps, Netflix and Dropbox. The service is purchased, hosted on the internet and can be accessed on any device, which is ideal for organizations with simple, minimal data collaboration and exchange requirements.
PaaS (Platform as a Service) solutions similarly work over the internet, but the difference is that instead of providing access to the application itself a la Dropbox, they provide the platform upon which the software can be built. The solution is developed, not purchased, which means that you can create applications that are customized for the business within the PaaS provider’s framework.
Amazon Web Services, Google Compute Engine and Microsoft Azure are all categorized as IaaS (Infrastructure as a Service). These big-ticket cloud solutions provide the hardware and software to give your organization true control and customization over applications, servers, storage, network and operating systems.
Now, let all that information sink in. Deciding on the right cloud solution can be daunting because of the many pros and cons—a lot like ordering from a menu.
