Good luck de ning cloud computing l.jpg
(Good Luck) Defining Cloud Computing

  • Software-as-a-Service

    • “My customer resource management (CRM) system is out on the Internet!”

  • Grids vs. Clouds

    • Shared Virtual Resources

    • Batch Jobs vs. Online Applications

    • Different Approaches to State Management

  • Network Diagrams

    • A service is “on a cloud somewhere”

  • Virtualization Platforms & APIs

    • Hardware can be manipulated with software


What problems are we trying to solve l.jpg
What problems are we trying to solve?

1. Cost

2. Scalability

3. Flexibility

4. Availability

5. Portability

6. Collaboration

7. Enable new stuff that we couldn't do before!



The cloud datacenter view l.jpg
The cloud - datacenter view

  • Massive build-out happening right now

    • Google, Microsoft, Amazon, Yahoo are tier 1

    • HP (EDS), IBM, Rackspace?

  • Scale is key


The cloud logical view l.jpg
The cloud - logical view

  • The Cloud: The Universe of all Web Services


The cloud definitions and hype l.jpg
The "cloud" - definitions and hype

Is the "cloud":

  • Infrastructure aaS?

    • Grid / utility / "on demand" computing

    • Shared utility

    • eg Amazon EC2

  • Platform aaS?

    • Ready-for-deployment scalable application platform

    • Google apps, Force.com, Heroku, Bungee Labs

    • Microsoft! (Azure)

  • Software aaS?

    • Used to be called "application service providers"

    • Multitenanted architectures: SalesForce.com,Xero

    • ...many, many others (3000 worldwide at least)

  • Wide area SOA?

    • "Universe of all (web) services"

    • WS-* and REST (and Etch?) standards

    • Data as a service? (StrikeIron)

  • *aaS?

    • "Universe of all economic services"

    • Can traditional "services" (law, accountancy, plumbing) be included in the logical Cloud?


Idc definitions sept 2008 l.jpg
IDC Definitions (Sept 2008)

Cloud Services = Consumer and Business products,

Services, and solutions that are delivered and consumed in

real-time over the Internet

Cloud Computing = an emerging IT development,

deployment and delivery model, enabling real-time delivery

of products, services and solutions over the Internet (i.e.,

enabling cloud services)

(From http://blogs.idc.com/ie/?p=190)


Key cloud services attributes l.jpg
Key cloud services attributes

  • Off-site, third-party provider

  • Accessed via Internet

  • Minimal/no IT skills needed to implement

  • Provisioning:

    • Self-service requesting

    • Near-real-time deployment

    • Dynamic and fine-grained scaling

  • Pricing model:

    • Fine-grained

    • Usage-based (at least available as an option)

  • User interface: browsers and their successors

  • System interface: Web services APIs

  • Shared resources/common versions (customization "around" the shared resources)

According to research firm IDC

Microsoft Windows Azure

The Azure™ Services Platform (Azure) is an internet-scale

cloud services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services that can be used individually or together.


What problems will come up l.jpg
What problems will come up?

1. Regulatory Issues

2. Legislative Issues

3. Geopolitical

4. Security Vulnerabilities

5. Application Architecture

6. Hardware dependencies

7. Control over your servers

8. Cost of the cloud

9. If it Ain’t Broke Don’t Fix it




A cloud technology reference model l.jpg
A Cloud Technology Reference Model

Begin with the Basic Data Center


A cloud technology reference model20 l.jpg
A Cloud Technology Reference Model

Add easy software access to:

Elements - HW/SW/Network/Storage Settings, Installations, and Configurations

Resources - Reservations from a pool of excess capacity in storage, computing, and network


A cloud technology reference model21 l.jpg
A Cloud Technology Reference Model

Add some visibility:

A Web of Metadata (What uses or contains what other things?)

Lifecycle (when and how can things change?)


A cloud technology reference model22 l.jpg
A Cloud Technology Reference Model

Add some real-world context:

Governance (Who has authority / responsibility to change, and how?)

Architecture Views (How are my concerns addressed?)

Implications for it strategy organization l.jpg

Cloud will be part of an expanding portfolio of options

Along with Traditional On-Premise and Next-gen On-Premise

Implications for IT Strategy & Organization

If organization is a “visionary” or “pragmatist”, it’s time now to start getting experience using Cloud offerings

  • Phase-in Cloud where the advantages tip the scales

SOA – especially as an IT management approach – is essential to flexible and integratable IT services sourcing

  • Cloud services will allow some offload of SOA implementation to cloud services providers, and speed the Dynamic IT journey

IT skills portfolio will continue to shift

  • Supplier Mgt, Web Svcs Dev/Integration, Bus. Process Insight

  • IT Ops “boiler room”, Application technical specialists


When to use cloud services now l.jpg
When to use cloud services now?

  • Non-sensitive binary object storage (docs, pdfs, images etc)

    • use S3 or similar NOW!

  • Moving server hosting to the Cloud: business case needs developing

    • Management tools not mature

    • Not ready for Enterprise apps - but soon

  • Azure will be a key player for PaaS

    • Google, SalesForce(?) main competitors

    • Lots of niches

  • SaaS

    • When setting up a new business, use it now! Don't saddle your business with expensive, inflexible, rapidly depreciating assets you don't need!
