  1. Summary of Enterprise Computing Models

  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

  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…

  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!

  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?

  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

  7. Enterprise Dimensions (Software Landscape) • Monolithic ERP • External integration systems • SaaS • PaaS • IaaS • These topologies are not mutually exclusive

  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

  9. Enterprise Dimensions (SaaS)

  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

  11. Enterprise Dimensions (PaaS)

  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

  13. Enterprise Dimensions (IaaS)

  14. From WikipediA

  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

  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

  17. Cloud Drivers

  18. Cloud Drivers • From http://www.sei.cmu.edu/reports/10tn009.pdf

  19. Cloud Barriers • From http://www.sei.cmu.edu/reports/10tn009.pdf

  20. Guidelines • So how do we build our enterprise architecture? • We won’t answer this question today

  21. Decision Factors • Make vs. buy • Choice of vendor or technology • Internal staff vs. consultants • Hardware in or out of the cloud

  22. AND NOW ON TO THE ERP SYSTEMS THEMSELVES

  23. Market Share

  24. (Short) List of SAP users http://global.cmich.edu/programs/content/mba/CompaniesWhoUseSAP.pdf Same say 97% of S & P companies use SAP in some way Some say it runs international business

  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

  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

  27. Costs to Implement (3)

  28. Costs (SAP ByDesign)

  29. Costs (Salesforece) • http://www.salesforce.com/crm/editions-pricing.jsp

  30. BIG DATA WHAT IS BIG DATA?

  31. Big Data (Characteristics) • This is our enterprise data warehouse fed by • Transactional systems • External systems • Unstructured data

  32. Big Data (Options) • Hadoop and the Hadoop Distributed File System (HDFS) • SAP HANA
