The concept of utilizing resources in these networks is being adopted by businesses both large and small throughout the world. These resources are categorized to describe their function, and include:
- Infrastructure as a Service (IaaS)- In the most general terms, Infrastructure as a Service means that companies may no longer need to own and house their own back-end servers and other network computing infrastructure except for internet-connected PCs, Laptops, Tablets or Smart Phones in order to maintain business functionality. (NB Only worry about understanding this If you have more than 25 users and multiple branches)
- Platform as a Service (PaaS)- Platform as a Service is also known as 'Cloudware', and refers to the availability of development tools in creating web applications and services to the end user. (NB This applies only if you are software developer or IT professional)
- Software as a Service (SaaS)- Software as a Service is defined as software applications that are subscribed to and accessed only through the Internet, and not installed on local PCs or Laptops. Almost everything that you do on the Internet right now falls into this category These solutions are gaining tremendous popularity, because end users do not need to install, update and maintain software locally - only connect to it and use it when the need arises. Eg: Gmail, Outlook, Skype, Xero Accounting, Salesforce CRM, MS Office 365
- Web 2.0 describes the whole of the social networking movement on the Internet, and includes but is not limited to destinations such as Facebook, MySpace, eHarmony, LinkedIn and Twitter. These sites offer the ability for people from all over the world to share common interests, stay connected and learn more about each other - and these sites aren't just for the young. Statistics show that the over 50 generation is logging onto these sites in greater numbers than ever before. In fact, in one month alone, Facebook adds over 17,000 new members many of whom fall into this group.
