What is Cloud Computing?

Traditional Model Cloud Computing Model Proprietary internal IT resources Remote, shared services Company A Company B Internet Company A Company B

What constitutes Cloud Computing?

Utility Pricing “Utility Pricing” • Pay-as-you-go • Pay-as-you-grow • Low up-front investment • Purchase resources on-the- fly

Auto-elasticity “Auto-elasticity” “Utility Pricing” • On-demand resource configuration • Massively scalable • Scale up or down

Virtualization “Auto-elasticity” “Utility Pricing” • Abstraction of execution environment “Virtualization” • Resource quota • Reduced number of physical machines

Management Automation “Auto-elasticity” “Utility Pricing” • One-click provisioning “Management • Policy based resource “Virtualization” Automation” allocation • Automated backups • Real-time disaster recovery

Third-party ownership “Auto-elasticity” “Utility Pricing” • Focus on core-business “Management • Leave rest to someone else “Virtualization” Automation” • Don’t worry about system maintenance etc… “Third-party ownership”

Some examples that uses Cloud…

IEEE GOLD Singapore • Interest group • Members work in different places • They need to share different documents • They need to maintain a GOLD email in conjunction with their company email SOLUTION:

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, MRT stations, taxi stands; access real-time estimates of next bus arrival times SOLUTION:

Different types of services…

Three kinds of services SaaS • Software as a Service (SaaS) • Platform as a Service (PaaS) • Infrastructure as a Service (IaaS) PaaS IaaS

SaaS • An application is hosted as a SaaS service provided to customers across the network • E.g. Google Apps, Web-based PaaS email, facebook applications IaaS

PaaS SaaS • Deploy customer created applications to a Cloud • E.g. Facebook platform, Google PaaS App-engine IaaS

IaaS SaaS • Rent resources such as CPU, storage and network capacity • Customer has control over the PaaS OS, storage and applications • E.g. Amazon Web Services IaaS

Challenges in Cloud Computing…

• 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. COURTESY: http://acet.rdg.ac.uk/~mab/Talks/Clouds-La-Coruna09/Talk.ppt

• 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 COURTESY: http://acet.rdg.ac.uk/~mab/Talks/Clouds-La-Coruna09/Talk.ppt

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 COURTESY: http://www.openforum.com/idea-hub/topics/the-world/article/8-tips-to-getting-started-in-cloud-computing-guy-kawasaki

Future of Cloud Computing…

Conclusion Google Trends shows that Cloud is going to sustain for sometime cloud computing grid computing distributed computing

Numbers!!! • By 2011 cloud computing market will reach $160 billion. • 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.
