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.

- 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 Spark & Associates 12
