Q

What are “shrink wrap” and “click wrap” licenses? How do they work? Characteristics?

A

Shrink Wrap - “If you tear the shrink wrap,” you are agreeing to our legal contract (EULA). When you open it, you agree to the contract terms

Click Wrap - More for downloading software. “You have to click agree in order to use their software.” Most of these license agreements are a “take-it or leave-it” type scenario. They don’t modify it for individuals.

Q

Multi-user licenses – what are their characteristics? How are “per user” licenses tracked?

A

Multi-User Licenses:

Per User and Concurrent (How many people are using the software at the exact same time) there is negotiating back and forth that could happen with multi-user licenses.

Per User Licenses:

A contract covering multiple customers and could cover them in different ways. Usually done in how many people will be using the software and only the people they purchased for will be allowed to use it. (Ex: purchasing 20 contacts for 20 employees that need to use the software)

  2. Clear statement of goal.
  3. Requirements clearly stated.
  4. Version control - avoid “feature creep”.
  5. Have effective project management techniques
23
Q

What are the elements of software TCO?

A

Acquisition Cost - either money you pay for software licenses, or the cost of people’s salaries to develop the software

There are beyond the price tag things like: deployment, planning, customization, integration, testing, migration, installation,training, user support, maintenance, upgrades, administration, lost productivity

24
What is TCO?
Total Cost of Ownership Not just the initial purchase, but the additional purchase to maintain and properly use the technology
25
Be able to explain the “free puppies” metaphor.
"Free beer" is actually free, while "free puppies" have high TCO (i.e. vet trips, food, toys, etc.)
26
______% of total IT cost occurs after initial purchase.
80%
27
_______% of IT projects fail
68%
28
What top two causal factors were described?
Poor business analysis Poor requirements specification
29
What “fixes” can help maximize the chances of project success?
Need realistic goals — State them clearly. Requirements specifications — Don't make assumptions, be explicit, document everything. IT and business team need to be on the same page, business drivers must match goals. Project needs a champion (leadership). Avoid "feature creep," communicate regularly. Evaluate and address risk. Pay attention to testing, need real project management skills.
30
Be able to explain the three aspects of IT project failure.
1. Time: Not ready on time 2. Cost: Project goes over budget. 3. Result: If the project doesn't deliver desired results
31
By “flux” we mean change – disruptive change that is impacting the software industry. What are some key potential “treasure” outcomes of these three disruptions to the software industry?
Open Source Cloud Virtualization
32
Flux - Open Source
Brings new competition and innovation to the software industry, reduce cost, and entry Done by a shared group of people who collaborate together on the internet and share their work
33
Flux - Cloud
Brings incredibly scalability on demand - only pay for what you need, reduced cost The idea that you don’t have to have your own expensive data storage system when you can use someone else’s out there on the Internet
34
Flux - Virtualization
Brings flexibility - run Windows on a Mac, etc. Term used when one computer can run multiple workloads at the same time, actively doing the work of many computers Flexibility for consumers, environment impact
35
Is OSS truly free?
No license fee (doesn't mean free) Free redistribution, derived work, source code, technology-neutral
36
OSS - Access to source code - what are the benefits of having the code?
Fix bugs yourself Modify behavior Add features
37
OSS - Community - what does the community do? Who are they?
Not just code — Collaborative development, Support resource, Contribute Anyone can view and modify
38
What support options exist for OSS software?
Powerful software - Linux OS - Apps - Enterprise and Desktop Community - Agile Development - Support Potential savings
39
LAMP stack – What is it? What are its components? How is it used?
A powerful open source platform (OS, web server, database, and programming language) that has been used to build some of the most powerful, popular web applications in use today Linux, apache, MySQL, Php No license fee
40
What is meant by “the cloud”?
The idea that you don’t have to have your own expensive data storage system when you can use someone else’s out there on the Internet
41
SaaS
Software as a service — Salesforce, Google Apps, Office 365 Don't buy hardware, don't install software, don't have to patch/upgrade rapid deployment, scalability, operating expenses (Monthly bill based on # of users) EX: Bob's Biscuits wants to use a cloud-based CRM application to track their customers. BB is a small company and doesn't have any programmers; they can't build their own solution.
42
PaaS
Platform as a service Amazon Web service, Windows Azure Don't buy hardware, don't build expensive datacenter, install your own software 7x24 support for platform scalable (probably), operating expense, 24/7 support Needing a database to create you own stuff. EX: Mike's Music wants to build a custom solution to manage their stores. They don't have a datacenter, so they want to put their custom solution in the cloud.
43
DaaS
Desktops as a service Citrix, Amazon Web Service, Dell You pay per desktop, per month. Gold Image - your techs design exactly what the perfect company computer should look like. Rapid scale up/down. EX: Tara's Tax service plans to hire 100 temporary employees soon. Rather than buying each one a PC, the company wants to host virtual PCs in the cloud for these temporary hires
44
Federated Authentication – What is it? Why is it important to enterprise customers?
- Log in credential to log into ALL of the cloud services - Single Sign-On (SSO) - Minimizes user support - Integration can be tricky
45
What is SSO?
Single Sign On — Gator Link
46
Name the three federated authentication technologies discussed in lecture
Shibboleth, Saml, Oauth
47
Be able to explain the risks of cloud computing
Authentication — Standards-based federated authentication Vendor Stability — You want to find a vendor that provides Security Risks — Regulatory compliance; vulnerability assessments and forensics Consumerization
48
Explain measures that cloud customers can take to minimize risk, including... Audits - including AICPA SOC 2
AICPA: Availability, confidentiality, privacy, processing integrity, security Customer audit To ensure that third-party service providers protect client data
49
Explain measures that cloud customers can take to minimize risk, including... Data location
Must be in EU, U.S., etc.
50
Explain measures that cloud customers can take to minimize risk, including... What is meant by "look behind the curtain" when discussing cloud solutions?
When you buy services, know where they get their services If you have American locations, you need to make sure your services is also American; no outsourcing
51
Explain measures that cloud customers can take to minimize risk, including... Exit strategy
Contract Data (retrieve your data, format, ensure vendor destroys all copies)
52
What is virtualization?
A way to take advantage of physical hardware resources that are underutilized (more value for our money)
53
How does virtualization solve the problem of underutilized hardware?
Technique for running multiple “virtual computers” on a single physical host computer system Breaks it up to give the person only what they need, i.e., 1 GB or 16 GB, instead of wasted space just sitting there
54
What is workstation virtualization? How can it be used in business?
Multiple OS on a single physical host machine Virtual Machine (VM) portability — you can copy and move to another desktop Security (Test, Snapshot) — test software in VM without risking host integrity Snapshot — restores VM to previous status. Great for testing
55
What is server virtualization? How does it reduce a company’s IT costs?
The masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users Consolidation: - Underutilized, reduce hardware cost, pooled resources - Most servers grossly underutilized - 20+ VM per PM is common -- VM - Virtual Machine --PM - Physical Machine Server Rooms / Datacenters: - No space, cooling, or power available, reduce server room costs - BIG SAVINGS - Reduce cost, space, energy, furnishing (racks, KVM, cabling)
56
What is Pre Virtualization?
Pre Virtualization — Physical hardware resources (CPU, Memory, Storage, NIC) Running multiple virtual computers on a single physical host computer system
