This document discusses cloud computing fundamentals and key cloud platforms and services. It covers: 1. An overview of building the first "Hello World" application in Windows Azure and using data access. 2. The main cloud computing models of IaaS, PaaS, and SaaS and examples of each. 3. A comparison of load balancing, failover, scalability, tooling, health monitoring and storage between Windows Azure and traditional hosting.

Windows Azure
2.Build your first cloud application “Hello World”.
3.Build a cloud application with the data access.
4. Web Role, Worker Role
5. The Azure Fabric and the Development Fabric
6.Sample case study- Think solution without cloud.
Amazon Web Service (AWS)
7.Building application using AWS.

3. Cloud computing refers to computing on the
Internet, as opposed to computing on a desktop.
Cloud computing refers to computers and
applications that run remotely and are accessed
over the Internet.
In cloud computing, virtual machines run in large
data centers and replace physical PCs and servers

IaaS(Infrastructure as a service) Virtual-machine disk
image library, block and file-based
storage, firewalls, load balancers, IP addresses, virtual
local area networks etc. Examples : Amazon
EC2, Rackspace.
PaaS(Platform as a service) Operating
system, programming language execution
environment, database, web server etc. Examples :
AWS Elastic Beanstalk, Heroku, Force.com, Google App
Engine.
Saas(Software as a service) Examples : Google
Apps, Microsoft Office 365.

Windows Azure Vs Traditional Hosting
Load Balancing
Computing resources can all be transparently load-balanced behind a
virtual router
Failover
If your data is load-balanced between multiple data centers, and one data
center goes offline, a cloud computing provider should be able to failover
Scalability:
The number of compute resources used should automatically scale up or
down based on demand.
Tooling
Health monitoring
OS maintenance The Azure Guest OS images are updated frequently
Durable storage Data is triple-replicated, so there's no risk of data loss.
Consumption-based
services.
Everything is a la carte; you pay for what you use. There's no specific
monthly commitment for a given set of servers.
Dedicated virtual machines.
