Activity Definition

Rehost Redeploy the app to a different hardware environment .Only changes are to the hardware infrastructure

Refactor

Make code / configuration changes to connect the app to new infra services Degree of difficulty is based on requisite code changes, which can vary from none to widespread

Revise Modify or extend the existing codebase to support legacy modernization requirements, then use Rehost or Refactor options to deploy to cloud Legacy code must be retained, for which there is frequently no documentation and/or institutional knowledge

Rebuild Rebuild the solution on a provider’s application platform by discarding the existing application code and rearchitecting the application for a new containerLegacy code does not need to be retained

Replace Discard an existing application (or set of applications) and use commercial SaaS

Data

ACCESSING ON-PREMISE

PublicOn Premise

Domain joined cloud nodes appear on the local network and access on premise data stores and legacy application data.

Synchronizing sets of data. Sets can be set to synchronize only relevant and allowable data, i.e. exclude PII. In cloud to cloud, user specific data in cloud to device.

SCALING

json

PublicOn Premise

On premise data that is frequently accessed is packaged in a file (xml, json), put in blob storage, and made available via CDN.

BIG DATA

Use cloud scale to process big data and make result available to on premise reporting and external devices via services

PULL BACK

Data from a public cloud hosted app is pulled back to on premises. The data is combined with other on prem data stores for analytics and reporting.
