Some Opportunities
![Page 16: The Magic of the Cloud: Supercomputers for Everyone, Everywhere Prof. Eric A. Brewer UC Berkeley](https://reader036.vdocument.in/reader036/viewer/2022062309/56649eac5503460f94bb24f0/html5/thumbnails/16.jpg)
Software Engineering
Cloud is much too dynamic!– Doesn’t need to perfect 1st time
• New version every day• Test versions on random users
– “Agile” rapid processes win
Accelerates innovation:– Low capital, rent capacity on demand– Build a new site by yourself in one day
• And it will scale as needed!
Need to rethink Software Engineering
![Page 17: The Magic of the Cloud: Supercomputers for Everyone, Everywhere Prof. Eric A. Brewer UC Berkeley](https://reader036.vdocument.in/reader036/viewer/2022062309/56649eac5503460f94bb24f0/html5/thumbnails/17.jpg)
Energy
The Cloud uses tremendous energy– Already 0.5% of global carbon footprint– And fastest growing segment
… but easier to optimize– Move cloud near power sources– Co-design power & cooling– Redesign servers, processors,
networks, …
Energy can be a Big Win

Security & Privacy
The Cloud stores all your Data– And what you do online– And enables deep analysis &
correlation– … forever into the future
Research can make a difference:– How to detect/prevent/track leaks?– How to enforce deletion?– What rights should you have?
Great Risk & Great Opportunity

Enabling the FutureSupercomputers for everyone, all the time … but need rural broadband access
Rethink most of life:– Health Care: new capabilities meets privacy– Education: supercomputer for every student– Science: a revolution in science
• Grand scale simulation, e.g. climate modeling
– Productivity: US leads the Cloud Revolution
A Historic Shift in is Progress
