The Yin and Yang of Software
The document discusses emerging trends in software and services including: 1) Software as a Service and cloud computing which allows software to be delivered and consumed "as a service" with service level agreements. 2) The growth of massive data centers which are becoming large physical assets requiring significant capital expenditures. 3) The rise of "Dev-signers" or designer-developers who are combining development and design skills. 4) The integration of software and services will be key as local software interacts with internet services to provide combined capabilities.

- 4. Trend #1 Software asa Service and Cloud computing i.e. Getting software “from the cloud”
- 5. … “as aservice” has been around for a very long time
- 6. the problem isthat you often get food like this… actually, not a big problem, unless…
- 7. …the expectation ishaving food like that…
- 8. Industry Average vs.Competitive Advantage ?
- 9. Separating logical servicefrom infrastructure has also been around for a long time… Service Layer: British Airways Infrastructure: British Airports Authority
- 10. Remember users onlysee the service layer (BA), when infrastructure (BAA) breaks… this happens:
- 11. And although itis the infrastructure (BAA) that broke the service layer (BA) pays the high price… • Customer dissatisfaction -> increases churn • Out of pocket expenses reimbursing: – £100 Hotel – £50 Transportation – £25 Food • £175 x 20‟000 people is a lot of £ (3.5Million) • Did British Airport Authority provide an SLA? • Where there penalties for non honoring the SLA?
- 12. Of course, ifyou can afford it, you can always decide to reduce external dependencies and opt for “more control”
- 13. Wait a second…am I in the wrong room? I am a software architect, why are you telling me all this, what is the point with Software?
- 14. Because… • SaaS andCloud computing is all about delivering and consuming services and SLAs • Most of the concepts discussed before are valid • At (very high) level: – SaaS is about: Delivering (software) services (with SLA?) – SOA is about: Consuming (software) services (with SLA?)
- 15. Do it yourselfvs. “as a service” ? More Control (usually) Lower Cost Do It Yourself Use the service Considerations: What is the SLA of “the service” Is it Core competencies vs. Commodity Compliance …
- 16. It is aboutwhich kind of risks you want to manage Up front cost vs. Long term cost Capex ($) risk vs. Supplier risk
- 17. Business Architecture andCapability Maps • Do you know how many services you run? • Can you rank them in priority order?

- 23. Energy Consumption • In2006, U.S. data centers consumed ~61 billion kWh of energy • ~1.5% of the total electricity consumed in the U.S. that year •total cost of electricity was $4.5 billion •more than the electricity consumed by all color televisions in U.S. • equal to consumption of ~5.8 million average U.S. households •If the status quo continues, by 2011: • data centers will consume 100 billion kWh of energy • at a total annual cost of $7.4 billion. • requiring construction of 10 additional power plants • As an Industry Segment, Data Centers are the fastest growing Energy Segment in the US .
- 24. Sustainability • Regulations • CarbonTax • PR / Image
- 25. To Datacenter ornot to Datacenter? That is the question Increased Regulation on the Horizon Department of Energy – Data Centers fastest growing Energy Segment in the United States EPA has just completed a report to Congress on Data Center power usage and consumption Difficult to find operational expertise Data Center Capital expense becoming a barrier for many companies

- 53. “Hope for thebest” architecture ?! Redundancy is very costly 2 bandwidth providers Is the bandwidth coming from 2 separate fibers loops 2 power suppliers (grid, diesel) is diesel coming from 2 oil distributors are the diesel distributors sourcing from 2 oil countries … Faulty service is very costly Lower sat, churn, SLA penalties Which one of the two above is more costly?
