What is SaaS

1

• SaaS (Software as a Service) is a type of service
  in which applications are hosted in centralized
  cloud and this hosted application can be used by
  user via web browser over the Internet. It can
  also be considered as a service where end users
  are able to access software application by using
  their internet enabled devices.
• You do not have to bother about installing and
  maintaining software instead you can easily use
  it via Internet. So it eliminates you from
  maintaining hardware management and complex
  software. This type of services is hosted on
  cloud and Google, Facebook, Twitter, etc. are
  the typical examples who use SaaS.
• SaaS applications are also known as hosted
  software, on-demand software or web- based
  software. In SaaS model, software vendor hosts
  and maintains the server and takes care about
  security, availability and performance. This is a
  significant change from the on premise software
  delivery model. SaaS clients can free themselves
  from buying software and hardware.
• What Characteristics do SaaS Possess?
• Multi Tenant Architecture
• In this type of architecture, all application and
  user can share single and common infrastructure
  which is centrally maintained by vendor.
• Ease in Customization
• Each user can customize the application as per
  their business need and it will not affect
  common architecture. These customizations are
  unique for each company and it is always
  preserved through upgrades. It implies that SaaS
  providers or vendors are able to upgrades more
  often, with least client risk and lower adaption
  cost.
