Everything as a service
The English used in this article or section may not be easy for everybody to understand. (April 2012)
Everything as a service(EaaS, XaaS, *aaS) is a concept of being able to call up re-usable, fine-grained software components across a network. It is a subset of cloud computing. The most common and successful example is software as a service (SaaS), but the term as a service has been associated and used with many core components of cloud computing including communication, infrastructure, data and platforms.
A number of vendors including Google, Microsoft, Hewlett Packard and Amido have been associated with the "everything as a service" trend.
Key characteristics[change | change source]
Offerings tagged with the as a service suffix have a number of common attributes, including:
- Low barriers to entry is a common method of offerings, with services typically being available to or targeting consumers and small businesses.
- Little or no capital expenditure as infrastructure is owned by the provider.
- Massive scalability is also common, though this is not an absolute requirement and many of the offerings have yet to achieve large scale.
- Multitenancy enables resources (and costs) to be shared among many users.
- Device independence enables users to access systems regardless of what device they are using (e.g. PC, mobile,...etc.).
- Location independence allows users remote access to systems.
