Why Is the Cloud Preferred to In-House Hosting? (cont'd)

Why Now?

C o p y r i g h t © 2 0 1 6 P e a r s o n E d u c a t i o n , I n c

• Time-sharing vendors sold slices of computer time on a use-fee basis since 1960s

• Cloud-based hosting advantages

– Cheap processors, essentially free data communication and data storage

– Instantaneous creation of new virtual machine environments

– Internet-based standards enable cloud-hosting vendors to provide flexible, standardized processing capabilities

Q2: What Network Technology Supports the Cloud?

smartphones, automobile entertainment systems

Connecting Your LAN to the Internet

Important ISP functions:

to telecoms

Mbps for typical LAN wireless

Q3: How Does the Cloud Work?

The cloud resides in the Internet

Carriers and Net Neutrality

C o p y r i g h t © 2 0 1 6 P e a r s o n E d u c a t i o n , I n c

telecom providers known as carriers

• Peering agreements - Carriers freely exchange traffic amongst themselves without paying

access fees

• Net neutrality principle, where all data is treated equally

Internet Addressing

• Public IP addresses

– Identifies a particular device on public Internet

– Assigned by ICANN (Internet Corporation for Assigned Names and Numbers

– U.S Department of Commerce no longer has oversight over ICANN

• Private IP addresses

– Identifies a device on a private network, usually a LAN

– Assignment controlled within the LAN

Public IP Addresses and Domain Names

• IPv4

•URL (Uniform Resource Locator

Three-tier Architecture

Watch the Three Tiers in Action! Sample of Commerce Server Page

C o p y r i g h t © 2 0 1 6 P e a r s o n E d u c a t i o n , I n c

1. Commerce server requests shoe data from DBMS

2. DBMS reads from database, returns data to commerce server

3. Commerce server formats Web page with data and sends html version of page to user’s

computer

4. Customer places items in shopping cart

5. Customer checks out, commerce server program processes payment, schedules

inventory processing, arranges shipping, email receipt to customer

Protocols Supporting Web Services

(no longer an acronym)

Protocol for requesting Web services and for sending responses to Web service requests.

XML

(eXtensible Markup Language)

Markup language used for transmitting documents Contains much metadata that can be used to validate format and completeness of a document, but includes considerable overhead (see Figure 6-15a).

JSON

(JavaScript Object Notation)

Markup language used for transmitting documents Contains little metadata and is preferred for transmitting volumes of data between servers and browsers While the notation is the format of JavaScript objects, JSON documents can be processed by any language (see Figure 6-15b).

Example XML Document

Q4: How Do Organizations Use the Cloud?

Three Fundamental Cloud Types

Content Delivery Networks from Cloud Vendors

C o p y r i g h t © 2 0 1 6 P e a r s o n E d u c a t i o n , I n c

• Content delivery network (CDN)

– System of hardware and software stores user data in many different geographical locations and makes data available on demand

– Provides specialized type of PaaS, but usually considered in its own category

– Minimize latency

– Used to store and deliver content seldom changed

CDN Benefits

• Why Should I Worry About Geotagging?

How Does Geotagging Work?

• iPhone with geotagging enabled

• Emailed, opened on PC using free IrfanView

• Image properties (EXIF data) contain laundry list of

metadata including GPS latitude at N 40 45.41 0 (40.756833) and longitude at W 73 59.21 0 (73.986833).”

• Creates “finger print” of record based on its content If record is changed, fingerprint will indicate it was altered (original

record would not be preserved)

• Ability to overwrite or erase records stored on these systems makes them non-compliant with Rule 17a-4(f)

• Excludes extrinsic controls authentication, passwords, and manual procedures

• Meets requirements of SEC’s Rule17a-3) and similar rule set out by Commodities Futures Trading Commission, when
