Software as a Service (SaaS) offers users access to software applications via the internet without having to install and maintain the applications themselves. SaaS provides users with more IT capabilities from any location using any device without the expense and complexity of owning and maintaining the infrastructure. With SaaS, users pay a subscription fee to access fully managed applications and updates are handled in the cloud, eliminating the need for local IT support. SaaS is beneficial for both individuals and businesses as it provides flexible access to applications using only an internet connection while simplifying costs and IT management.

1. Software as a Service
Use more Software + Pay less

2. Do you want more IT with less trouble?
More IT
Anywhere: home, public locations, enterprises, customer/partner sites
Anyhow: no more setup, fluid experience
Any device: mobile, tablets, computers without expensive resources needs
Less trouble
Human errors
Complexity, instability
IT infrastructure to maintain
Operations to care: backup, security, version upgrades
Available expertise: server, network, storage, virtualisation...

3. Software as a Service is for YOU!
Basically, SaaS is
New licensing model : subscription per usage, per month, per quarter, yearly
New delivery model : no more store, CD/DVD to buy, download from a central place :
the cloud
Basically, SaaS is not
A new software release : the content doesn’t change
A new type of ownership : as soon as you stop paying, you have no more access
Sometimes, it’s a bit confusing when :
The software editor wants to move to SaaS and abandon the legacy model
The SaaS comes with different versions : express, standard, enterprise, enterprise
plus, etc.
One doesn’t really know what features are important or not

4. Subscribe
A simple example: Microsoft Office
Buy software and install
for each user

5. Subscribe to
SharePoint

6. Who should I be interested?
Individuals who care about:
Easy start, no installation
Free for limited usage
Basic needs covered: email, files sharing
Minimum costs : 1 $ for extra storage of 50 Gb
Corporations who care about:
No budget to invest upfront
Pay per use
Stop paying anytime

7. Why should I be interested?
Both Individuals and corporations :
Need only to have a decent mobile, tablet or laptop
Use the power in the cloud (servers, network, storage)
Benefit from Cloud services (data backup, version upgrade)
Corporations are empowered:
Simpler cost structure, all-inclusive
No need to have a large IT department to get extended service
No need to buy servers and manage its obsolescence
IT more aligned to business needs
Using apparently unlimited resources in the Cloud

8. How may I start using SaaS?
Four easy steps:
○ Choose a software you are comfortable with, say Office
○ Open the Internet browser
○ Search for the SaaS version
○ Follow instructions
Warning
○ The same SaaS is not relevant for both individuals and corporations
○ Software still differ, for instance Office 365 is different from Google Docs
○ You may need to migrate your legacy IT to SaaS. It’s an extra cost
○ You need to migrate eventually everything in the Cloud, else it may cost you more

9. Software
as a Service
SaaS, scorecard
Buy
software
● The software is yours for ever
● You buy as many licences as
many employees you have on
the day of purchase
● You need to be sure who needs
the software
● If an employee leaves, you keep
the licence unused until another
employee comes
● You are supposed to pay
maintenance fees yearly
● You pay for the usage only
● You pay as your employees
start using the software, and
stop when they are done
● You don’t need to be sure who
needs the software
● If an employee leaves, you
saves money, as much as when
he or she doesn’t use
● Maintenance fees are included
in the pay per use price
