Image Construction Ideas

Idea: Layered Design

The bottom: The system layer, to build their own application of different operating system image;

Middle Layer: Based on the operating environment, such as PHP, Java, Python, and so on, to build Business foundation environment layer Image;

Top-level: Build application service layer mirroring based on specific business modules.
