Challenges

• Networking issues:

• Normal operations in the cloud are slow - avoid calls to backend from UI thread

• Frequent but small operations should be avoided. Optimise by buffering and/or packaging.

• Updating server status is a pain. Avoid to pull, or optimise transport, backend logic, and front end logic (to not pull when status can be assumed).

Challenges• WTP Server model for (local) server do not fit for cloud

scenario:

• Server = Application (SAP HANA Cloud Platform)

• Server = Space (Cloud Foundry)

• Probably there are other …

• Server is usually representing a scalable artefact (Compute Unit, VM, Instance …) that have a single runtime.
