Summary of Enterprise
Computing Models
Slide 2
Enterprise Dimensions Who does what?
In-source out-source hardware and software
Staff vs. consultant What does the software and hardware
landscape look like? Monolithic (SAP R3) Service-based SaaS
Slide 3
Infrastructure Options (Who Does What) In-house sole source (SAP) (ORACLE)
(PEOPLESOFT) Multi-vendor solutions Out of building infrastructure
The cloud (SALESFORCE)
And a mix of the above…
Slide 4
In-house Implementations The company provides care-and-feeding
of their ERP systems Requires significant expertise and long-
term investment Without expertise and upper-
management commitment, this will not work!
Slide 5
Multi-vendor Solutions One-size fits-all is not always enough
Adoption of SalesForce.com by companies are on the rise
Third-party front-end integration engines Duet, ERP connect
Challenges Authoritative data? Integration and migration Reintroduce the age old silo problem?
Slide 6
Out of Building Infrastructure Activities are performed by third-party
providers Consultants Hosting / licenses Application service providers And all of this in the clould
Slide 7
Enterprise Dimensions (Software Landscape) Monolithic ERP External integration systems SaaS PaaS IaaS
These topologies are not mutually exclusive
Slide 8
Enterprise Dimensions (SaaS) Software as a Service We are talking about the Salesforce.com
“on-demand” software platforms. TurboTax online is a good personal example Pricing is subscription-based They are multi-tenant
SAP offers ByDesign as a Web-based pay-as-you-go platform

Enterprise Dimensions (SaaS)
Slide 10
Enterprise Dimensions (PaaS) Platform as a Service It’s a means of provisioning hardware
and the applications that run on the hardware A solution stack
I can purchase an SQL Server instance from http://www.rackspace.com/managed_hosting
Azure fits this mold
Slide 11
Enterprise Dimensions (PaaS)
Slide 12
Enterprise Dimensions (IaaS) Infrastructure as a Service Formally define, this is a more “raw”
service I give you a VM to do with as you please You need to take care of the software
ecosystem and licences
Again, Rackspace offers these services

From WikipediA
Slide 15
And the Cloud? In summary, the cloud implies the use
of dynamically allocated resources instead of statically allocated resources I’m no longer provisioned a VM or physical
resource, I’m provisioned Compute power / disk / bandwidth on a
pay-as-you-go basis Amazon / Rackspace / and many others
Slide 16
Cloud (Types) We often categorize clouds as
Public: Resources are offered as a pay-per-use service over the Internet
Private: Resources are hidden behind a firewall and managed by the organization
