Quiz 1 Results:

Average – Curved grades ASSUMING YOU ARE OK with connect
9:30AM class 30.7/40    12:30pm class 29.9/40   4:00pm class 32.8/40
34+ –> A
28-33.5   –> B
22-27.5 –> C
< 22 –> Less than C

Also shown is connect grade (circled number)
Connect – Out of 10 (5 smartbook/cases INCLUDING Appendix A). If you didn’t get 10, I will take late smartbook for 80% credit.  Note smartbook bug is showing 0% if submitted at all late- I will adjust this.

Simnet Labs are finishing up next week and due April 6th 11:59PM – Don’t forget to do LinkedIn assignment (setup a LinkedIn page, and link your Simnet “White Belt” credential) and email me your LinkedIn URL (format is like http://linkedin.com/in/jonfrankel)

Note final is Thursday May 22.  Do NOT make travel plans before – this is the only opportunity to take it.

Ch 5 Infrastructure – Blue prints for systems.  Talk about cloud systems first…

-Support Operations (current systems)
– Support Change (Future systems)
– Support Environment (E-Waste & Cloud)

Operations –
Downtime – HW crashes, Natural Disasters, Floods, earthquakes, 9/11 (from Ch 4 – fig 4.7)
– D/R strategy – Disaster/Recovery – How to get techie stuff back up and running
“Cold Site” – Restore data into that site. Time delay (“Warm site”)
“Hot Site” – Real time data available all the time. Very $$ (like Fidelity example)

Business Continuity Planning – More than systems
– Testing, Phone chains, All the logistics beyond the techie stuff.
– Physical Buildings – Where will people work

Change – Capacity Planning – Nice chart that we buy more than we have
– Lots of terminology here – most important (IMHO) is Scalability – How long can I keep running with current systems
–> being replaced by cloud computing (see below)
– 5 9s (99.999) availability standard, and how redundancy leads to fault tolerance and make it possible

E-Waste – Electronic Waste
– Rare Earth Elements (and other fun things like lead, mercury…)  – not good for environment!
– Only about 20% of e-waste is really recycled.
– Recycling is not always done properly
– Growing problem with no good solutions

Power Consumption – Cloud service / data centers use a tremendous amount of electricity. – This number is only going up, especially with AI.  And leads to more carbon emissions too.

Cloud Computing -IMHO this is the BIG change in MIS over the past/next decade
– All data is available all the time.
– In the old days, software wasn’t that good in the cloud
– Salesforce does great MIS systems in the cloud

Features – Capacity Planning (Support Change)
– Traditionally been difficult – Pay for more than you needed, upgrade frequently
– With the cloud, pay for what you use and can use as much as you want.  Like power grid.
– Way fewer resources like hardware & software (also includes people, who can collaborate easily)
– Backups & upgrades are automatic
– Disaster/Recovery automatic
– Systems Development is much simpler (more on this in chapter 9)

Downsides :
– Security – If hacked, or company goes out of business, then who knows what happens
(but they can probably do security better than most companies)
– They can raise prices easily or possibly sell your data
– Reliant on the Internet – These days, it is 100%* reliable
– Limited by the features they give you (which are usually fine)
– Don’t worry about the differentiation between types of cloud models (Iaas vs SaaS vs PaaS)
