The “Cloud” = 10X Improvements

Ease of UseScalabilityRiskReliabilityCost

Ease of Use

Deploy infrastructure with a mouse or API No cabling, screwdrivers, racking, unboxing, buying Middle of the night Do it yourself remotely from anywhere anytime

Reliability

Based on enterprise grade hardwareDesign for failures:

Automatically spin up replacements Use multiple clouds

Cost

“Turn off the lights” = turn off servers you aren’t using Ex: Turn off development and test environments

Pay for only what you useNo need to buy in advanceZero Capital Outlay No contracts

“Breaking the Dam(n!)”

Colocation – 1st step to outsourcingManaged Hosting – dedicated servers

managed by 3rd party take some pain awayCloud Hosting – Lower cost, easier, lower

risk, more reliable

UNDERSTANDING HOW EXPERTS VIEW “CLOUD COMPUTING”

Multiple Definitions

Forrester Research

“A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption1”

1- “Is Cloud Computing Ready for The Enterprise?” Forrester Research, Inc.

Other Definitions

“Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services.” – IBM press release on “Blue Cloud”

“…a hosted infrastructure model that delivers abstracted IT resources over the Internet” – Thomas Weisel Partners LLC from “Into the Clouds: Leveraging Data Centers and the Road to Cloud Computing”

“Cloud computing describes a systems architecture. Period. This particular architecture assumes nothing about the physical location, internal composition or ownership of its component parts.” – James Urquhart blog post

Multiple Graphic Descriptions of the “Cloud”

PERSPECTIVE VIEW OF “CLOUD COMPUTING”

Redefining the definition

Defining the Segments

SaaS Software as a Service Storage as a Service

PaaS – Platform as a ServiceIaaS – Infrastructure as a Service

Colo vs. Managed vs. Cloud Hosting

Colocation Managed Cloud

Time Weeks to Months Days to Weeks Minutes

Scalability Slowest, Rigid & Costly

Slower, somewhat flexible, Costly

Instant, Flexible, Pay-per-usage

Cost High CapEx Costly, sometimes month/year contracts, no CapEx

No contracts, usage based, no upfront costs

“Green” Low Low High - virtualized

Pricing model Buy Servers & Colo costs whether used or not

Rent Servers & Hosting costs whether used or not

Rent based on usage only

Hosting Industry Ripe for Change

Technology has evolvedPeople demand more controlInstant gratificationIn-house too costly from CapEx and Human

CapitalColocation for those who want to be physically

Cloud Computing is…

… virtualized compute power and storage delivered via platform-agnostic infrastructures of abstracted hardware and software accessed over the Internet. These shared, on-demand IT resources, are created and disposed of efficiently, are dynamically scalable through a variety of programmatic interfaces and are billed variably based on measurable usage.

Cloud “Applications”

SaaS resides here Most common Cloud / Many providers of different services Examples: SalesForce, Gmail, Yahoo! Mail, Quicken Online Advantages: Free, Easy, Consumer Adoption Disadvantages: Limited functionality, no control or access to

underlying technology

Cloud “Platforms”

“Containers” “Closed” environments Examples: Google App Engine, Heroku, Mosso, Engine Yard,

Joyent or Force.com (SalesForce Dev Platform) Advantages: Good for developers, more control than

“Application” Clouds, tightly configured Disadvantages: Restricted to what is available, other

dependencies

Cloud “Infrastructure”

Provide “Compute” and “Storage” clouds Virtualization layers (hardware/software) Examples: Amazon EC2, GoGrid, Amazon S3, Nirvanix,

Linode Advantages: Full control of environments and infrastructure Disadvantages: premium price point, limited competition

Cloud “Extenders” (Wild Card)

Provides extension to Cloud Infrastructure and Platforms with basic functionality

Examples: Amazon SimpleDB, Amazon SQS, Google BigTable Advantages: Extends functionality of Compute & Storage

Clouds to integrate with legacy system or other clouds Disadvantages: Sometimes requires use of specific Platforms

or Infrastructure

Cloud “Aggregators” (Wild Card)

Sits on top of various Cloud Infrastructures for management Examples: RightScale, Appistry Advantages: Provides more options for Cloud environments Disadvantages: Dependent on Cloud Providers
