GearUp: “No, I Mean 25 Cents an Hour.”

• Gearup’s Web hosting costs rising rapidly

• Lucas suggests provisioning Web servers

and databases in the cloud

• Provision server resources by the hour

• Costs: $50/mo plus 25-cents per hour for

processing time used

• Could yield huge savings

LAN Protocol

IEEE 802.3

• Wired LAN

• 10/100/1000 Mbps

• Ethernet

IEEEE 802.11

• Wireless LAN

• 802.11n

• Bluetooth

TCP/IP Protocol Architecture

Application Layer Protocols

Hyper Text Transport Protocol (http)

HTTPS - secure HTTP data transmission

Simple Mail Transfer Protocol (SMTP )

File Transfer Protocol (ftp)

TCP and IP Protocols

TCP or Transmission Control Protocol

• Breaks traffic up into packets and sends

each one along its way

IP (Internet Protocol)

• Routers

IP Addressing

Public IP Addresses • Identify a particular device on public Internet

• Public IP addresses must be unique, worldwide

• Assignment controlled by ICANN (Internet Corporation for Assigned Names and Numbers)

Private IP Addresses

• Identify a particular device on a private network

Major benefits

1. Public IP: All devices on LAN share a public IP address.

2. Private IP address, need not register computer with

ICANN-approved agencies.

Functions of the LAN Device

• Switch processing: IEEE 802.3 wired LAN traffic

• Access-point processing: IEEE 802.11 wireless LAN traffic

• Translating between IEEE 802.3 and IEEE 802.11

• Converting between Analog and Digital

• Assigning private IP addresses

• Converting IP address between private and public IP addresses

• Routing packets

• And more …

Public IP Addresses and Domain Names

•Four decimal dotted notation like

165.193.123.253

Domain name

•Worldwide-unique name affiliated with a

public IP address

•Affiliation of domain names with IP

addresses is dynamic

URL (Uniform Resource Locator)

Remote Access Using VPN

WAN Using VPN

Q4: What Processing Occurs on a

Typical Web Server?

Watch the Three Tiers in Action!

Hypertext Markup Language (HTML)

XML, Flash, Silverlight, HTML 5

XML (eXtensible Markup Language)• Fixes several HTML deficiencies• Program-to-program interaction over Web

• Browser add-on for animation, movies, and other advanced graphics inside a browser.

Silverlight

• Browser add-on with greater functionality than Flash

HTML 5.0 • Supports animation, movies, and graphics

Ethics Guide: Personal Work at Work

You email 12 pictures of your surfing skills from New Zealand to a friend at some company in Ohio.

Each picture is 6.2 megabytes in size.

Packets of email and picture transmitted to Ohio company router and from router to its email server.

Your message consumed processing cycles on router and email server. A copy of your pictures stored on email server until your friend deletes them.

Friend uses company LAN to download the pictures to his desktop computer.

Friend reads his email during his working hours.

Q5. Why Is the Cloud the Future for

Most Organizations?

• Elastic leasing of pooled computer

resources over the Internet

Elastic

• Dynamically increasing/decreasing a

leased resource programmatically in a

short span of time, and only pay for

resource used

Why Is the Cloud Preferred to In-House

Hosting?

Cloud On Site

Positives:

Small capital requirements Control of data location

Speedy developmentIn-depth visibility of security and

disaster preparedness

Superior flexibility and adaptability to

growing or fluctuating demand

Known cost structure

Possibly best of breed security /

disaster preparedness

No obsolesce

Industry-wide economies of scale

hence cheaper

Why Is the Cloud Preferred to In-House

Hosting? (cont’d)

Negatives:

Dependency on vendor Significant capital required

Loss of control over data location Significant development effort

Little visibility into true security and

disaster preparedness capabilities

Annual maintenance costs

Ongoing support costs

Staff and train personnel

Increased management

requirements

Difficult (impossible?) to

accommodate fluctuating demand

Cost uncertainties

Obsolesce

When Does the Cloud Not Make Sense?

Only when law or industry standard practices

require physical control over the data

Private cloud

• In-house hosting, delivered via Web

service standards

Q6. How Can Organizations Use the

Cloud?

Q7: 2022?

Cloud computing benefit

• Individuals on iCloud

• Small groups using Office 365

• Startups Using PaaS

• Huge organizations using IaaS

New categories of products and services

Create new jobs?

Tele-action

• Telediagnosis, telesurgery, telelaw enforcement

Guide: Thinking Exponentially Is Not

Possible, But…

Humans cannot think exponentially

• No one could imagine the growth in

magnetic storage and what we would do

with it (1990s).

Exponential growth in:

• Number of Internet connections

• Web pages

• Amount of data accessible on Internet

Guide: Thinking Exponentially Is Not

Possible, But…(cont’d)

• What can we do to better anticipate

• People want to do what they’re already

doing, but more easily; they want to solve

problems that they already have.

• Hedging your bets

Position yourself to move quickly as

direction becomes clear

• Error increases exponentially as time frame

increases

Ethics Guide: Human Networks

Matter More

• Social networks are crucial in connecting

• Build personal social networks for success

• Six-degree theory

You are connected to everyone on the planet by no more than six degrees of separation

• Successful professionals consistently build personal human networks

• People you know the least contribute the most to your network

Check Customer Credit Process

Using Process Diagrams to Identify

Process Problems

Process problems1. Operations Manager allocates inventory to orders

as processed

2. Credit Manager allocates customer credit for orders in process.

– Allocations correct, if order accepted

– If rejected, allocations not freed, inventory still allocated and credit extended for orders not processed

Possible fix: Define an independent process for Reject Order

How Can Business Processes Be

Improved?

1. Add more resources

• Adds costs unless efficiencies of scale

2. Change process structure

• Reduce work and costs

• Increase costs and increase

effectiveness to offset

3. Do both

Q4: Which Comes First, Business

Processes or Information Systems?

Many-to-Many Relationship of Business

Processes and Information Systems

Build Business Processes First

Build Information System First

Classic Five-step Systems Development Life Cycle

Another Factor: Off-the-Shelf Software

If starting with business processes first

– Likely to choose package for processes

being developed, but not later processes

If starting with information systems

– Likely to choose package that works for all

users, but, business processes will get

short shrift.

And the Answer Is . . .

In theory:• Better to start with business processes

• More likely to result in processes and systems that are aligned with the organization’s strategy and direction

• In practice:• Organizations take both approaches

• Off-the-shelf software:

• Start with business processes and select application that works for those processes
