以雲端資料儲存為主之應用開發系統

Abstract

In the tide called Cloud Computing, people move their applications

previously running on on-premise servers to the new environment, the Cloud, to

reduce cost needed investing in IT infrastructure. However, this migration is not

a comfortable trip. The offered environments, Google App Engine for instance,

have several issues concerning compatibility. In other words, compatibility

should be one of the crucial concerns for those who want to enjoy the benefits of

the Cloud.

Due to the problem of compatibility, it is reasonable for the enterprises

to decide to move certain portions of their IT infrastructure to the cloud. And

database is one important piece that may be migrated to the cloud.

In this thesis, a database model backed by Google App Engine data-store

which can be consumed by on-premise application is introduced. This work will

address several issues to provide the on-premise applications access to data-store

in the cloud while guarantee efficiency and compatibility.
