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

Slide 9

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

Slide 13

Enterprise Dimensions (IaaS)

Slide 14

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

Slide 17

Cloud Drivers

Slide 20

Guidelines So how do we build our enterprise

architecture? We won’t answer this question today

Slide 21

Decision Factors Make vs. buy

Choice of vendor or technology Internal staff vs. consultants Hardware in or out of the cloud

Slide 22

AND NOW ON TO THE ERP SYSTEMS THEMSELVES

Slide 23

Slide 24

(Short) List of SAP usershttp://global.cmich.edu/programs/content/mba/CompaniesWhoUseSAP.pdf

Same say 97% of S & P companies use SAP in some waySome say it runs international business

Slide 25

Costs to Implement (1) License fees from $2000 to $5000 per

year Maintenance fees are about 15% - 20% of

license fees Internal solutions tend to be more

expensive than cloud-based solutions

Slide 26

Costs to Implement (2) Assume $3000 / user and a 50

concurrent user company License cost is $150,000 Maintenance cost is 18% of license costs Consulting 1.2:1 consulting / license costs Internal costs 1:1 license costs
