This document discusses how to think like the cloud and prepare for cloud business. It explains that the cloud is not magic and cannot solve complexity, but can provide elasticity. It advises analyzing applications to see which parts are best for the cloud. Using examples of Homer's shopping mall growing and needing expansion, it shows how to distribute applications across cloud services like EC2, RDS, and S3 for scalability. It also provides examples of using hybrid cloud and cloud services for tasks like DDoS protection, HPC, and streaming. The conclusion emphasizes thinking distributed and elastic and finding the best cloud solutions.

Cloud is not a Magic Carpet.

5. What is the Cloud?
Misunderstands
• Cloud can support perfect redundancy.
• Current applications can be migrated into cloud easily.
• Oracle RAC can be migrated into cloud, what a perfect idea!
• Expect high performance with low price.
• Fully secured service will be provided.

6. What is the Cloud?
But the truth is…
• Without “distribution”, the cloud could be useless.
• If you really need to use Oracle, use it in your house, not on cloud.
• Build/migrate your application can be distributed.
• Without “automation” you’ll get suffered by operation nightmare.
• You have to deal with security without h/w based firewalls.
• If you wrote wrong application on cloud, you may get paid more.

12. What is the Cloud?
• Analysis your system architecture and service needs, and find
out which is best part to migrate.
– Does our DB architecture really need relations?
• Migrate from small/easy components like,
– Light weight web service first. ( file send )
– Session sharing
– Simple DB, not SAN based one. ( CouchDB, MySQL, etc )
– PHP based web applications.
– Most expandable part of your system.
• Think about Distributed application architecture

15. How to think like Cloud
Someday,
Simpson thinks about
Web shopping mall.

16. How to think like Cloud
But he’s got in trouble
with ….
• Buying Service components
- Which spec? How many?
- Switches?
- 2 year contract?
• Licenses
- Databases?
- Web servers?
• And more.

17. How to think like Cloud
So, he googled about it, and realizes
Amazon EC2 service!
He decides to launch his shopping
mall application with EC2.
EC2 Means
Elastic Compute Cloud

- MySQL
- Expandable as business

- Get paid as much as I used.

19. How to think like Cloud
CREATE A VM in EC2!
Apache
PHP Create php codes and Image, DB.
MySQL Keep the source tarballs in PC.
Backup DB before VM shutdown.

Understand Cloud Architecture
• What kind of service solution fit into Cloud?
• Guide cloud limits and application architecture to
customers.
• Suggest hybrid Cloud model if they already have
infrastructure.
• Lean technologies like NoSQL, BigTable, and how to
distribute systems & applications.
• Lean automation skills

29. Conclusion
• It’s very important to think like cloud.
• Cloud cannot solve complexity.
• Enterprise needs simplify, elasticity.
• There will be many of applications for cloud. We have
to find what is best solution for where.
• Web Front-end ( HTML5, Javascript ) skills are
getting greater day by day.
