1. COMS E6998-6 Cloud Computing and Data Center Networking
Sambit Sahu

2. Course Scope
Graduate level seminar course on Cloud Computing and Data Center Networking: This is a seminar course on Cloud Computing and Data Center Networking intended to provide students exposure to recent advances in these areas. The target audience is graduate level students with the knowledge of operating systems, computer networks and web services. It is expected that students will read and present research papers and work on a course project. The course project is intended to motivate students to identify and work on engineering as well as research issues in these areas.
The first part of the course will focus on broad range of topics in Cloud Computing - starting with overview of technologies that enable IaaS Cloud such as Amazon EC2, provisioning and monitoring, storage cloud, elasticity and resource provisioning, and cloud applications. The second part of the course will focus on the recent advancements on data center networking and OpenFlow based network architecture design.
First part: Cloud Computing
Provisioning and automation
Enterprise cloud: moving to cloud
Resource scaling
Storage cloud
Applications and programming models
Security and privacy
Energy issues
Second part: Data Center Networking
New data center network architecture and design
Open Flow based network architecture and research

3. Requirements from Students
Students will present and critic papers % grade
Presenter presents the paper
Others need to critic the paper ( me the critic)
There will be standard template for presentation and critic
Course project % grade
Students may team up
Two choices
Project: come up with a project idea and carry out the project
Compile a report: choose 10 papers in a particular topic and turn in a detailed report
Project Ideas
Discuss with instructor to decide on a course project
Initial list of choices will be provided
Team up to work in groups

4. Course Structure Each week
Background material (if any) covered by instructor
2-3 papers will be presented by students
Discussion on possible research issues
Guest speakers on engineering and research issues
Any hands-on experience/demo

5. What is Cloud?
Allows users to request computing resources through web interfaces
Extreme automation through virtualization
Hide away physical resource details
Hide away tedious and error prone configuration issues from users
Provides an utility view to computing resources
Pay as you go
Resources on-demand

6. Different versions of Cloud
IaaS
Amazon EC2
Open Source: Eucalyptus, Open Nebula
PaaS
GoogleAps, Azure
SaaS ….

7. Why Cloud? User does not need to own and configure machines
Management of infrastructure left to cloud providers
User needs to only worry about what to do with the machine/resource – not how to prepare it for that purpose
Request resources when needed
Simple web based interface for
request resource
monitor and manage resource
Extreme scaling
Can scale the footprint from 1 server to servers in a matter of few minutes or less
Economic model
Rent vs lease
Different models makes sense for different usage pattern
Management cost is often higher than resource cost

8. Life Cycle in a typical Cloud Operation
User of a cloud
APIs to request a machine
Build and load virtual machine images with software stack
Request and attach storage
Attach IP address
Request monitoring capabilities
Cloud administrator
Manage physical resources
Manage virtual resources

9. Some Research Topics in Cloud Computing
Provisioning and automation using virtualization
Enterprise cloud: moving to cloud
Resource scaling
Storage cloud
Applications and programming models
Security and privacy
Energy issues
