A broad and deep platforms that helps customers to build sophisticated, scalable application. 2

Cloud Computing: XaaS Terms SaaS: Software as a Service. eg. google

doc/group, Microsoft cloud services, iCloud.

PaaS: Platform as a Service. Amazon EC2 Windows 2008 $0.12/hr (server license included) Linux $0.085/hr

IaaS: Infrastructure as a Service, Vmware supports IaaS

Continued.. StaaS: Storage as a Service. Carbonite ($59/yr),

Amazon S3 (0.14/GB, month; 0.01/1000reqs) Maas: Monitoring as a Service

Amazon EC2

EC2 stands for Elastic Compute Cloud. EC2 provided an API which supports

every OS. It allows us to configure capacity with

minimal friction. Elastic IP address: Not static not dynamic

but elastic.

14

Amazon EC2 Functionality Select a pre-configured, template image to

get up and running immediately. Configure security and network access on

your Amazon EC2 instance. Choose which instance type(s) and operating

system you want, then control all of them by web services.

Pay only for the resources that you actually consume, like instance-hours or data transfer. 15

It provides a web services interface to store and retrieve data.

Amazon S3 uses buckets to store data over the cloud.

Bucket is a simply container for objects. Buckets are similar to internet domain

names. They are accessed via bucketname.s3.amazonaws.com

Amazon Simple Storage Service (S3)

18

Amazon S3 Functionality Allows unlimited storage of objects(Files)

containing of 1 bytes to 5 gigabytes each. Objects consists of the raw object data and

metadata. Objects are stored and retrieved using a

developer-assigned key. Data are kept secured from unauthorized

access through authentication mechanism.

19

Continued..

Objects can be made available to public by the http or bittorrent protocol.

A bucket and key together uniquely identify each object in s3. Every object can be addressed through bucket and key combination.

It creates repository for every version of uploaded files.

20

Amazon Simple Queue Service (SQS) SQS is a distributed queue messaging

service. It supports programmatic sending of

messages via web service application as a way to communicate over the internet.

It is a fail-safe service. Example of messaging service

technologies include Java Message Service and Microsoft Message Queuing.

21

Amazon SQS Functionality Redundant infrastructure Multiple writer and reader Configurable settings per queue. Variable message size Access control Delay queues.
