SaaS
(software as a service)
What is SaaS (software as a service)?
Software-as-a-service, or SaaS for short, is a
cloud-based method of providing software to users. SaaS users subscribe to an
application rather than purchasing it once and installing it. Users can log
into and use a SaaS application from any compatible device over the Internet.
key aspects of SaaS:
Cloud-based:
SaaS applications are hosted on the provider's servers
and accessed via the internet.
Subscription model:
Users pay a subscription fee to access the software,
often on a monthly or annual basis.
Managed by the provider:
The provider is responsible for managing the
underlying infrastructure, security, maintenance, and updates of the software.
Accessible on demand:
Users can access the software from anywhere with an
internet connection
Examples of SaaS applications:
- Office
productivity suites: Microsoft Office 365
- Customer
Relationship Management (CRM): Salesforce
- Email
services: Google Workspace
- Online
storage: Dropbox
- Streaming
services: Netflix
Benefits of SaaS:
- Cost-effective: No
upfront investment in hardware or software.
- Scalable: Easily
adjust resources as needed.
- Accessible: Users
can access the software from anywhere.
- Reduced
IT burden: The provider handles
maintenance and updates.
- Collaboration: Facilitates
real-time collaboration
