Deployment Approaches

Traditional Modular• OS + Applications in 1 image

• Image per hardware type

• Time to integrate new hardware

• High maintenance

• Requires a visit to the desktop

• Storage requirements

• 1 base image (OS) for all hardware

• Apps/drivers delivered as add-ons

• Easily integrate new hardware

• Reduced maintenance costs

• Automated build process

• Easy to customise
