The three types of cloud services your business may look at are typically grouped these categories;

  1. Software as a Service (SAAS)
  2. Infrastructure as a Service (IAAS); and
  3. Platform as a Service (PAAS)

Lets talk a little about what each of these are:

  1. Software as a Service (SaaS)

 SaaS is the most common form of cloud technologies. You can access internet-hosted software applications using a browser, rather than traditional applications stored on your own PC or servers. The software application host is responsible for controlling and maintaining the application, including software updates and settings. You, as a user, have limited control over the application and configuration settings. Examples of these software services include, document management, email, Bookings (e.g. eventrbright), applications such as Google Apps, Microsoft OneDrive, Dropbox, Evernote, Office 365, Survey Monkey, Skype, Google Hangouts, Mailchimp and Xero to name a few that we use. Some of these software applications provide powerful collaboration tools, meeting tools, productivity and planning tools, assessment and feedback or presentation tools.
  2. Infrastructure as a Service (IaaS)

 IaaS typically means buying or renting your computer power and disk space from an external service provider. This option allows you access through a private network or over the internet. The service provider maintains the physical computer hardware including CPU processing, memory, data storage and network connectivity. If the scale of a business customer’s operations fluctuate, or they are looking to expand, they can tap into the cloud resource as and when they need it rather than purchase, install and integrate hardware themselves.
  3. Platform as a Service (PaaS)

 PaaS can be described as a crossover of both SaaS and IaaS. Essentially you rent the hardware, operating systems, storage and network capacity that IaaS provides, as well as the software servers and application environments Platform as a Service allows users to create software applications using tools supplied by the provider. PaaS services can consist of preconfigured features that customers can subscribe to; they can choose to include the features that meet their requirements while discarding those that do not
