Web Services – Definitions We Ought To All Know About

Web services, SOA, everything-as-a-service: what exactly are each one of these terms? Exactly what do they mean for you? Here are some definitions when i discover their whereabouts:

SOA

Cloud Computing

Using Web Services.

Web Services

Software or data offered on the internet being an ongoing service as opposed to a custom-made or out-of-the-box software program or dataset (delivered, say, on CD)

DaaS
Data like a Service. Outsourcing data management to “the cloud” – either “public” data (for example street names) or personal information (for example stock lists).

Desktop like a Service: This term has not really caught on because of DaaS being generally restricted to “data like a service” or “database like a service”. Desktop like a services are an extremely better term for that more buzzword-y “Operating-system like a Service” not really a true operating-system (which boots in the computer and manages a user’s hardware sources) but a web-based desktop which stores your requirements and essentially functions being an interface for other web services, as being a normal desktop is really a user intterface for traditional software and knowledge.

SaaS
Software like a Service. Outsourcing software to some company “within the cloud” that runs the program, updates it, and enables business use of it for any charge.

PaaS
Platform like a Service. A bit of software delivered like a service that enables growth and development of 3rd-party apps to “plug into” it. Examples: Salesforce.com, Facebook.com

Lesser-known services underneath the umbrella “everything like a service”

CaaS
Communication like a Service. Delivering telecommunications, im etc. like a service on the internet. Telephony like a service, also referred to as “Voice like a service”, employs Voice over internet protocol (Voice Over Ip). Hardware and software could be provided like a service by providers.

IaaS
Infrastructure like a Service. Slightly tricksy one, this. Could be taken to be much like “Operating-system like a Service” or “Desktop like a Service”, Infrastructure like a Service typically dishes up services centred around hardware in addition to software. Wikipedia informs us that “servers, software, data center space or network equipment” are offered in IaaS.
