Overview

• What is cloud computing?

• What is Windows Azure?

• Scenarios

• Challenges

3

The big switch?

• From your own Burden wheel to large-scale

electricity…

• Large scale electricity was possible by a

series of scientific and engineering

breakthroughs

• But what ensured the triumph was not

technology but economics

• It changed our lives completely: we have

light everywhere and power at each house!

4

The next big switch?

• Cloud computing is moving away from the

personal computer to a public grid: The

Internet

• Centralized data processing

• Computing is turning into a utility

• Is driven by economics

• Is processing information the next electricity?

• Will this change our lives once again?

What is cloud

computing?

Cloud computing is Internet

("cloud") based development

and use of computer technology

("computing”)

What is the cloud?

• A set of connected servers

• Offers infrastructure, platform and software

as a service

• An infrastructure on which you can:

• Install and run services

• Store and retrieve data

• We have public and private clouds

9

Characteristics of the cloud

• The management/ administration of the

systems is not in hands of the user

• The user pays a recurring fee

• Pay for what you use (utility based

computing)

• The capacity of the infrastructure is elastic

• Strong focus on integration (cloud-cloud,

cloud-on premises)

Azure : designed for the cloud

• For easy access, from anywhere

• Language agnostic REST APIs

• Client libraries for .NET, Java, PHP, …

• For durability

• All data is replicated 3 times within a cluster, and

across datacenters

• For massive scale

• Data is automatically partitioned and load

balanced across servers

Windows Azure – coming soon…

• Programming model

• Administrator privilege in the VM

• Deployment of pre-configured VM images

• Storage

• User-selectable geo locations for replicas

• Secondary indices on tables

• Service management

• Remote terminal server access to VMs

Scenarios

Cloud platform scenarios

1. Running an on-premise app unchanged in

the cloud

2. Scalable web application

3. Parallel processing application

4. Web application with background

processing

Vendor lock-in?

• The interoperability story is quite good.

• Cloud platforms can expose and consume web

services en RESTfull interfaces

• Cloud platform data can be accessed by other

applications

• The portability story is quite different…

• It strongly depends, each vendor is doing it

differently

• Moving apps form on-premise to the cloud and

back is hard!
