Introduction

† “You can judge a leader by the size of the

problem he tackles. Other people can cope with the waves, it's his job to watch the tide.”

Introduction

† Cloud computing and social networks?

† What are their relationships?

† We have these two things: social network and cloud computing. Many of us use at least one of them, if not both of them, almost every single day.

Introduction

† Both CC and SN have great potentials.

† Combining them has many possible applications.

Issues

† Green Information Technology (green cloud computing, green social networks, etc.)

Issues

† Green data centers

„ Green for the environment

„ Organizations are under intense pressure to reduce their carbon footprints, even if they are growing and prospering. That pressure isn’t just coming from

environmentalists any more, but also from government, shareholders and customers.

38

Issues

† Green data centers

„ Green for the economy

„ Not only is electricity becoming a major expense in data centers, it is becoming the major expense for IT operations. And unfortunately, most of the

energy is wasted on overhead processes, rather than the value-creating computing itself.

Issues

† Green data centers

„ Green for avoiding a stop light

„ Regardless of the cost or consequences of runaway power consumption, many data centers are simply running out of power capacity, based on the energy available in their facilities or even from their local grids, endangering the reliability of current

operations and preventing growth or addition of new capabilities without investing in new facilities.

† Data Mining in Social Networks

Only use a simple algorithm:

Issues

† Many kinds of metadata (friendships, fan pages, societies, videos, pictures, “like”s, messages, etc.) to handle

† Social search

„ Search FB in Bing and search Tweet in Google

† Many can be done for the recommendation system

„ Recommend fan pages, societies, new wall postings, new pictures, new videos, etc.

Conclusions

† “Cloud computing and social networks are two of the more powerful movements in the web 2.0

space.

† So the potential of social media and the cloud integrating is compelling to say the least.

† Need customer service applications that try to capture the crowdsourced pools of knowledge

floating across the internet from sites like Google, Facebook and Amazon, and then uses this

information to better equip commercial customer service operations with useful knowledge.

60

Conclusions

† Social networks are becoming much more than an online gathering of friends; Facebook and Twitter are becoming destinations for ideation,

e-commerce and marketing.

† It’s of no surprise that companies want an easy and simple way to capture all of the information that is relevant to their businesses and then leverage this knowledge to improve customer service.
