Introduction to Cloud Computing
Introduction
Ever wondered how you are able to watch thousands of movies on Youtube instantaneously?
How about searching though billions of documents as done by Google?
Do you use facebook to play games, upload photos, where do all these stored?
Ever created a document in Google Docs?
IT as a service is known as Cloud Computing. In the past IT meant computers, infrastructure, computer scientists, electrical power, cooling, repair, etc.

Some examples that uses Cloud…
Pizzas from the Cloud…
• Availability is a critical requirement
• Spikes in demand
• Optimize computing capacity while being able to handle peak demand
SOLUTION:
Brewing customer feedback
• Build an online community to engage with customers and employees dynamically
• Required community management tools to track and implement the best ideas
SOLUTION:
Real-estate in Cloud
• Procuring and installing servers or upgrades are distraction
• Difficult to anticipate hardware demand
• Unanticipated hardware failures leads to terrible impact on productivity
SOLUTION:
Location-based commerce
• View map of your location, and surrounding businesses & services
• Discover what's new, what's on sale, at which stores around you
• Locate nearest bus stops, train stations, taxi stands; access real-time estimates of next bus arrival times
SOLUTION:
Different types of services…
Challenges in Cloud Computing…
Challenges…
• Requires a constant Internet connection:
– No internet means no access to even your own documents
• Features might be limited:
– This situation is bound to change
– For example, you can do a lot more with Microsoft PowerPoint than with Google Presentation's web-based offering.
– The basics are similar, but the cloud application lacks many of PowerPoint's advanced features.

Challenges…
• Stored data might not be secure:
– How secure is the cloud?
– Can unauthorized users gain access to your confidential data?
– Only time will tell if your data is secure in the cloud.
• Stored data can be lost:
– Theoretically, data stored in the cloud is safe, replicated across multiple machines.
– But data loss can happen

Getting started in Cloud Computing..
Getting started in Cloud Computing…
1. Know the different options available to you
2. Understand that scaling is a skill, not a default
3. Implement a disaster plan
4. Don’t be naïve
5. Budget for your specific use-case
6. Choose a cloud provider on your needs, not its popularity
7. Remember: some applications are not good fits for cloud
8. Think outside of the box

What do I do in my research?
Auction-based vs. Incentive-based Multiple-Cloud Orchestration Mechanism
With our schemes, the Cloud Service Providers (CSPs) can offer attractive dynamic pricing policies to the users
Users can choose appropriate CSPs based on their requirements.
Incentive-based Scheme
User submits the job requirements to Broker
Broker forwards this request to appropriate CSPs
CSPs offer the price based on user return ratio and load, and send to users through Broker
Users choose appropriate CSP which maximizes its utility calculated based on offer prize, security
index and affinity index
Auction-based Scheme
User chooses the desired CSP which has the maximum trust and reputation. User then sends this desired CSP
and bid price to Broker
CSPs also submit their minimum bid price for the resources to Broker
Broker declares the winner based on these parameters
User repeats its auction if the last auction is a failure

Future of Cloud Computing…
Numbers!!!
• The number of physical servers in the World today: 50 million.
• By 2013, approximately 60% of server workloads will be virtualized
• 50% of the 8 million servers sold every year end up in data centers
• The data centers of the dot-com era consumed 1-2 MW Today data center facilities require 20 MW, - 10 times as much as a decade ago
• Google currently controls 2% of all servers ( around 1 million) with it saying it plans to have upwards of 10 million servers in one decade
• 98% of the market is controlled by everyone else.
