Google App Engine is a platform for developing and hosting web applications in Google-managed data centers first released as a beta version in
April 2008.
Google App virtualizes applications across multiple servers and data centers. Google App Engine is free up to a certain level of used resources. Fees are charged for additional storage, bandwidth, or CPU cycles required by the application.[

Nebula is a Virtual Machine (VM) Hosting for Department of computer engineering, Kasetsart University. Private cloud is used for research and education Objective
Lower the maintenance cost Reduce power consumption Reduce space usage Provide more dynamic on demand services
Usage
Web and information services for each lab Test and development Database HPC using Virtual Cluster on the Cloud User request VM at http://nebula.cpe.ku.ac.th/ Admin reply with IP Address, Username and Password to access VM
Virtual Machine running on (VM) VM Node 1 – 6 VM Configuration an Virtual Disk can be kept on local Disk or on global shared storage . Local Disk is on VM Node Nebula use shared FS using NFS from Storage Node (RAID5) Use VMware Remote Console (browser plug-in)

Cloud computing is at an early stage Public cloud available from many vendors such as Amazon EC2, Google App Private and Hybrid cloud is a coming trends Cloud computing is still Need standard for things such as
programming API, Security mechanism
One of the technology with high potential that everyone should follow the development.
Governance
Security, Privacy and control SLA guarantees Ownership and control Compliance and auditing Sarbanes and Oxley Act
Reliability
Good servive provider with 99.999% availability
Cloud independence – Vendor lockin?
Data Security Cloud lockin and Loss of control
Cost? Simplicity? Tools Controls on sensitive data?
Big and small
Cloud provider goes out of business
Plan for moving data along with Cloud provider
Out of business Scalability and cost outweigh reliability for small
businesses
Big businesses may have a problem
