Software As A Service SaaS

Software As A Service - SaaS

• Ian Mitchell, FNZCS

2
What is SaaS? - Wikipedia

• Software as a Service (SaaS) is a model of
  Software Delivery where the software company
  provides maintenance, daily technical operation,
  and support for the software.
• Package software delivered over a network.

3
But now . . .

• Software as a service (SaaS) is a software
  application delivery model where a software
  vendor develops a web-native software application
  and hosts and operates (either independently or
  through a third-party) the application for use by
  its customers over the Internet. Customers pay
  not for owning the software itself but for using
  it.

4
More . . .

• They use it through an API accessible over the
  Web and often written using Web Services or REST.
  The term SaaS has become the industry preferred
  term, generally replacing the earlier terms
  Application Service Provider (ASP), On-Demand and
  "Utility computing".

5
Key Characteristics

• Network-based access to, and management of,
  commercially available (i.e. not custom) software
  
• Activities that are managed from central
  locations rather than at each customer's site,
  enabling customers to access applications
  remotely via the Web
• Application delivery that typically is closer to
  a one-to-many model (single instance,
  multi-tenant architecture) than to a one-to-one
  model, including architecture, pricing,
  partnering, and management characteristics.

6
Variations Deprecated Terminology

• ASP Application Solutions Provider
• Not just web front-ends SAP, Oracle
• Typically not hosted in house but maybe
• Turnkey rather than tailored - LiveUpdate
• Way to deliver BPO services
• Often billed per user per month
• Pure utility model pay for what you use
• Service Oriented Architecture (SOA)
• Software on Demand.

7
Definition of the Day

• Hosted remotely (typically in a web farm)
• Web front end only
• AJAX HTML, JavaScript (No Applets)
• Back end Database
• Usually multiple users different legal entities
• Billing Per user per month or similar
• Often Free trials.

8
AJAX

• Asynchronous JavaScript and XML
• Better first-time usability
• Controls appear/invisible during data entry
• Partial pages are downloaded to CSS2
• Typically text only hence faster screen
  handling
• Screens modified for specific user class
• Tailored DDLists and Enumerations.

9
Web 2.0

• Poorly defined term
• Includes Blogs
• RSS
• Social communities users tag content
• Highly personalised pages
• Forums
• Not particularly relevant.

10
Advantages

• No large upfront costs - usually free trials
• High levels of security physical, power, pipes
• No install costs low one-time costs.
• Little SysAdmin time
• Minimal training (if any)
• Anywhere, anytime, anyone - mobility
• Operating costs only can be terminated
  scalability No capex hoops.

11
Disadvantages

• Core functionality out-sourced perceived risk
• Broadband risk
• Limited personalisation/tailoring
• but AJAX
• No competitive uniqueness advantage
• Not suited to very high volume data entry.

12
New Business Models

• Mobile models any PDA
• Deliver to screen format in use
• Working out-of-office e.g. Real Estate Agents
• Salespeople who visit the client
• Build the plan and place the order there
• Hot-desking
• Virtual Organisations
• Franchise models
• Avoid peak travel times green solution.

13
Enhancements

• Introduced silently
• Only when multiple clients clearly want them
• In a way which does not impact other users
• No roll-out
• Simple conversational interface
• Irrelevant if all end-users not on same OS
• Minimum development costs test on single O/S
• Web apps are simpler to test because of page
  structure.

14
Security

• Client machines only hold cookies and caches
• Servers physically secure
• Servers run minimal software few ports
• No user downloads, no email to servers
• Data on separate machine with only 1 port via
  secure connection.

15
Open Source

• Not a particular issue
• But why use the products of a company which
  fundamentally opposes this approach?
• Why pay more?
• Will you ever know?

16
24/7

• Why ask for 24/7? Do you need it?
• 23.5 x 6.5 much, much cheaper.
• Expensive Dual servers special storage
• Do these apps need it?
• They are not your ERP apps.

17
Whose doing it?

• Google complete Java library
• Writely and spreadsheet
• Salesforce.com and CRM are hot 5 years
• Oracle and SAP have web interfaces
• BI to have web interfaces
• Web shopping sites are SaaS now
• Most mobile apps are actually SaaS now.

18
Cost of Roll-Out

• Was 1 SysAdmin per 30 PCs 1/50 thereafter
• Now better with Ghost and similar
• Then Citrix
• Now Virtualisation - WMware
• Cost of tailoring each individual users options
• Now done from any PC by privileged user
• Single sign-on desirable
• 1500 per PC to set-up Now lt99!

19
Cost of training

• Web forms and conversational modes
• Simpler forms less data intensive
• Confirmation of each step
• We understand usability now!
• Help actually there mouse over
• No manuals and packaging costs
• Product must be easy to use
• Or it wont survive the free trial
• Collaborative use my mates will show me
• Comfort because I can see the data.

20
Value to SMEs

• Smaller enterprises have an easier road to
  adoption and installation
• Need minimal (No?) technical staff
• More work from home
• More work on the street
• More work while traveling! New inflight options!
• SMEs are 80 of . . . Your market!

21
Support Desk

• Support link on every page
• Support desk can see which page you are on
• Automatic FAQ answer selection
• Flick to chat mode
• Delivered to users out in the field
• Can also go to own support desk for product help.

22
Ease of Maintenance

• Because there is only one copy of the software
  maintenance is substantially eased
• The software only runs in one environment an
  environment totally controlled by the supplier
• IE and Mozilla damn!
• But co-operation promised!
• Reduced operating costs.

23
Reduced Hardware Costs

• A single server handing multiple customers can be
  optimised no extra peripherals no VDU.
• Mass storage optimised
• No need for virtualisation
• Rack mounts
• Minimum cabling - at both ends.

24
Myths, Myths, Myths Jeffrey Kaplan

• 1. SaaS is still relatively new and untested.
• 5 years
• 2. SaaS is just another version of the failed ASP
  and hosting models of the past and will suffer
  the same fate as its predecessors.
• High density displays of data always were poor
  usability
• 3. SaaS only relieves companies of the upfront
  costs of traditional software licenses.
• Operating costs reduced as implicitly shared
• 4. SaaS is only for small and mid-sized
  businesses and will not be accepted by
  large-scale organisations.
• Bigger organisations have huge SysAdmin costs

25
Myths Business Week Online

• 5. SaaS only applies to applications such as CRM
  and Salesforce automation.
• Everything except high volume data and some
  technical apps
• 6. SaaS will only have a minor impact on the
  software industry and will fade over time.
• SaaS is the way to go
• 7. It will be easy for the established software
  vendors to offer SaaS and dominate this market.
• Always hard to move legacy giants
• 8. SaaS is only for corporate users.
• Always better for single users no install,
  updates, etc.

26
Conclusions

• SaaS will be the way most apps will be delivered
  not unique competitive advantage s/w
• All but high-volume data entry for large
  corporates and some specialised apps
• Much higher proportion of staff will have only
  PDAs or small footprint notebooks
• Low risk try b/4 you buy get the CxO ticks.
