Cloud Platform Apache cloudstack Intercloud Designing an architecture Clustering

Contents

Amazon EC2 :

Amazon Web Services (AWS), by allowing users to rent virtual computers

can create, launch, and terminate server-instances as needed

Cloud Platforms

Amazon s3 :

Online file storage web service provides storage through web services interfaces

Apache Cloudstack:

Act is an opensource Iaas platform Setup an on demand elastic cloud computing

service Allow endusers to provision resources

Deployment architecture overview

Region with multiple zones

Intercloud

 is an interconnected global "cloud of clouds" and an extension of the Internet "network of networks"

each single cloud does not have infinite physical resources

Facade : Provide a unified

interface to a setof interfaces in asubsystem

Designing an architecture

Adapters :

Convert the interface of a class into anotherInterface clients expect

Proxies :

Provide a placeholder for another object to control access to it.

n-tier web pattern : Three –Tier Architecture

Presentation TierBusiness logic TierData Tier

Clustering

Three –Tier Architecture

Fig. Three Tier Architecture

Semaphore :

Synchronization object that controls access

Widely used to control access Basic functionalities associated with

semaphores are set, check and wait

Locking :

Implemented using hardware instructions To support the implementation of storage

MapReduce P2P framework :

To perform job state replication, manage master failures, and allow participation of intermittent nodes

Using a P2P approach, extended the MapReduce architectural model

Three types of nodes1. User 2. Master 3. Slave
