Public Infrastructure Cloud• Examples

• Amazon Elastic Compute Cloud (EC2)• GoGrid, Joyent, Accelerator, Rackspace• AppNexus, FlexiScale, Manjrasoft Aneka

• EC2• leveraged via

• Web services (SOAP or REST)• Web-based AWS (Amazon Web Service) management console• EC2 command line tools

• AMI (Amazon Machine Images)• Different instance size

• Resource need (small, large, and extra large)• High cpu (medium and extra large high CPU instances)• High-memory (extra large, double extra large, quadruple extra large)

Private Infrastructure Cloud• Meet Security and Governance• Inside organization firewall• May within a cloud vendor’s data center• Characteristic

• Allow service provisioning and compute capability for an organization’s users in a self-service manner

• Automate and provide well-managed virtualized environments• Optimize computing resources, and servers’ utilization• Support specific workloads

• Examples• Eucalyptus• OpenNebula

• Hybrid Cloud

Virtualization Standardization• DMTF (Distributed Management Task Force)• VMAN (Virtualization Management)• VMAN OVF(Open Virtualization Format)• OGF (Open Grid Forum)• OCCIWG (Open Cloud Computing Interface Working Group)• new API allow:

• Consumers to interact with cloud computing infrastructure on an ad hoc basis.

• Integrators to offer advanced management services.• Aggregators to offer a single common interface to multiple providers.• Providers to offer a standard interface that is compatible with the

available tools.• Vendors of grids/clouds to offer standard interfaces for dynamically

scalable service’s delivery in their products.

Amazon EC2• Elastic Compute Cloud

• is a Web service• allows users to provision new machines • into Amazon’s virtualized infrastructure in a matter of minutes• Root access to AMI

• EC2 instance is typically a virtual machine with a certain amount of RAM, CPU, and storage capacity.

• Purchasing Model• On-Demand• Reserved• Spot

• Provisioning Services• Auto Scaling• CloudWatch• Elastic Load Balancer

Presented by Majid Hajibaba

Eucalyptus• Open Source cloud tool• Elastic utility computing architecture for linking your programs to

useful systems• Private cloud and hybrid cloud

• Amazon EC2,S3 interface

• Features• Interface compatibility with EC2, and S3• Simple installation and deployment• Support for most Linux distributions• Support for running VMs that run atop the Xen or KVM (VMWare?!)• Secure internal communication using SOAP with WS security• Administrator’s tool for system’s management and user’s accounting• configure multiple clusters each with private internal network addresses into a

single cloud

• Research Lines• service’s provisioning, Scheduling, SLA formulation, hypervisors’ portability
