“

How

About $10 Per Terabyte.”

Lease storage capacity from third party.All incoming data from drones automatically uploaded.Average monthly storage costs cut at least 50%.Power savings, backup time saved, no new hardware configuration.One-time set up and development costs.

Q2: What Network Technology Supports the Cloud?

Typical Small Office/Home

Office (

SOHO) LAN

LAN Protocol

IEEE 802.3

Wired LAN

10/100/1000 Mbps EthernetIEEE 802.11Wireless LAN802.11acSpeeds up to 1.3 Gbps

Bluetooth

Transmits

data

short distances.

Connect computer, keyboard, mouse, printer, smartphones,

smartwatches, automobiles,

sports equipment,

clothing.

Abbreviations Used for Communications and Computer Memory Speeds

equipment,

K(ilo) = 1,000, not 1,024 (as for memory); M(ega) = 1,000,000, not 1,024 × 1,024; G(iga) = 1,000,000,000, not 1,024 × 1,024 × 1,024.

Connecting Your LAN to the

Internet

Important ISP functions:

Provide legitimate Internet address. Provide gateway to Internet.Pay access fees and other charges to telecoms.WAN wireless average performance 1 Mbps, with peaks of up to 3.0 Mbps.Typical wireless LAN 50 Mbps.

Summary of LAN Networks

Q3:

How Does the Cloud Work?

The cloud resides in the

Internet

Carriers and Net Neutrality

Messages, broken into

packets. Packets move across

Internet, passing through networks owned by telecom carriers.Peering agreements - Carriers freely exchange traffic amongst themselves without paying access fees. Net neutrality principleAll data treated equally.Problem: some people use more bandwidth than others.

Internet Addressing

Public IP addresses

Identifies a unique device on

Internet.Assigned by ICANN (Internet Corporation for Assigned Names and Numbers.Private IP addresses Identifies a device on a private network, usually a LAN.Assignment LAN controlled.

IP Addressing:

Major

Benefits

Public IP addresses conservedOne public IP address per LAN. Using private IP addresses

Eliminates

registering public IP address with ICANN-approved agencies.

Protects against direct attack.

Public IP Addresses and Domain Names

Processing on a Web Server

What

happens when

Three-tier Architecture

Watch the Three Tiers in Action

Sample of Commerce Server Page

Commerce server requests shoe data from

DBMS.

DBMS

reads from

database, returns

data

commerce server.

Commerce server

formats Web page

with

data and sends html version of page to user’s computer.

Customer places items in shopping cart

Customer

checks out, commerce server program processes payment, schedules inventory processing, arranges

shipping, email receipt to customer.

SOA Analogy: Approval

Request

Interactions Among Three Departments

CheckCustomerCredit• ApproveCustomerCredit• VerifyInventoryAmount

• AllocateInventory

• ReleaseAllocatedInventory

Using SOA Principles, Each Department Defines:

CheckCustomerCredit

ApproveCustomerCredit

Inventory DepartmentVerifyInventoryAmountAllocateInventoryReleaseAllocatedInventoryEach department formally states data to receive with request and data promised to return in response.

Every interaction

done

exactly

same way.

Using SOA

Principles:

EncapsulationNo department needs to know

who works in another department, or how dept. accomplishes work. Each department free to change personnel task assignments, change processes for performing services.Falcon Security could dynamically create 1,000 Inventory Departments and Sales Department with no need to change anything it does.

SOA Principles Applied to

Three-tier Architecture

JavaScript

written to invoke these services correctly.

Protocols Supporting Web Services

WSDL, SOAP, XML, and JSON

WSDL (Web Services

Description Language)

Standard for describing services, inputs, outputs, other data supported by a Web service. Documents coded machine readable and used by developer tools for creating programs to access the service.

SOAP

(no longer an acronym)

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

XML

(eXtensible Markup Language)

Used for transmitting documents. Contains metadata to validate format and completeness of a document, includes considerable overhead (see Figure 6-15a).

JSON

(JavaScript Object Notation)

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

Example XML and JSON

Documents

Q4: How Do Organizations Use the Cloud?

Three

Fundamental

Cloud TypesCloud Services from Cloud Vendors

Content Delivery Networks from

Cloud Vendors

Content delivery network (CDN)

Stores user data in many different geographical locations and makes data available on demand. Specialized type of PaaS, but usually considered in its own category.Minimizes latency.Used to store and deliver content seldom changed.

CDN Benefits

Servers Used in a Typical

CDN Service

Using Web Services

Internally

Private Internet Infrastructure

Q5: How Can Falcon Security Use

the

Cloud?SaaS products

PaaS Services from

Amazon DBMS

Products with Elastic Cloud 2 (EC2)

Falcon Security could use CDN

to distribute content worldwide and respond to leads generated from

advertising.

IaaS Services at

Falcon Security

Provides

basic hardware in the cloud. May acquire servers to load operating systems. Considerable technical expertise and management.Alternative: Use elastic data storage services.

SaaS

and PaaS

provide more added value to Falcon Security.

Q6: How

Can Organizations Use

Cloud Services Securely?

Remote Access Using VPN: Actual Connections

Remote Access Using

VPN: Apparent

Connection

Private Cloud for

Inventory and

Other Applications

Accessing Private Cloud over a

Virtual Private

Network

Using A Virtual Private Cloud

Subset of a Public Cloud With Highly Restricted, Secure

Access

Q7: 2026

loud services

faster, more secure, easier to use, cheaper.Fewer organizations own their computing infrastructure.More pooling of servers across organizations.Overall size of the cloud gets bigger.Individuals, small businesses, large organizations obtain elastic resources at very low

cost.

Cloud fosters

new categories of

work.

Q7: 2026 (cont’d)

So What? "Net Neutrality Enabled"

ISPs

little control over amount

, type, or origin of content.30% of U.S. Internet traffic during peak hours associated with using Netflix.Net neutralityAll users and content providers treated equally.No “fast” or

“slow”

lanes.

ISPs not

allowed to block, or

slow

, content associated with

competitors.

ISPs can’t

charge heavy Internet users additional fees or taxes.

FCC Approved New Regulations (2015)

Renders

Internet a utility.Complaint: Interfering

with free markets.ISPs argue loss of potential revenue stream inhibits infrastructure development, limits growth, and stifles innovation. Larger war on net neutrality may have only just begun!Copyright © 2017 Pearson Education, Inc.Slide52
