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
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…
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!
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?
Out of Building Infrastructure

Activities are performed by third-party
providers




Consultants
Hosting / licenses
Application service providers
And all of this in the clould
Enterprise Dimensions
(Software Landscape)

Monolithic ERP
External integration systems
SaaS
PaaS
IaaS

These topologies are not mutually exclusive




Enterprise Dimensions
(SaaS)


Software as a Service
We are talking about the Salesforce.com “ondemand” 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-asyou-go platform
Enterprise Dimensions
(SaaS)
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
Enterprise Dimensions
(PaaS)
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
Enterprise Dimensions
(IaaS)
From WikipediA
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-asyou-go basis
Amazon / Rackspace / and many others
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
Cloud Drivers

So how do we build our enterprise
architecture?
We won’t answer this question today
Decision Factors

Make vs. buy



Choice of vendor or technology
Internal staff vs. consultants
Hardware in or out of the cloud
AND NOW ON TO THE ERP
SYSTEMS THEMSELVES
Market Share
(Short) List of SAP users

iesWhoUseSAP.pdf
Same say 97% of S & P companies use SAP in some
way
Some say it runs international business
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
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
