AVEVA™ Unified Engineering – Browser Access streams virtual desktop sessions using Amazon Web Services - Workspaces Applications (formerly Appstream 2.0) on-demand instances. These are pools of instances residing in a standby state ready to be launched on demand by users.

Workspaces Application (formerly Appstream 2.0) instances are launched from a "Golden Image" representing a managed blueprint of the Operating System and applications included in AVEVA™ Unified Engineering – Browser Access.
AVEVA™ Unified Engineering – Browser Access aims to deliver the latest version of AVEVA™ Unified Engineering in a fully patched and secure form. To achieve this, the "Golden Image" is updated regularly in relation to Operating System, Virus Scan Database and Application updates as part of automated build and dynamic delivery pipelines.

Streamed Desktops Fleet Capacity Policies

When users start their AVEVA™ Unified Engineering – Browser Access streamed desktop, a virtual desktop is delivered to their Browser from a fleet (or pool) of instances residing in a standby state ready to be launched on demand.

The fleet has capacity scaling policies to maximise instance availability for users, these policies are dynamically adjusted by the managed service based on the number of tenant users, historical usage and time of day.
A working hours window is agreed with the customer, outside of which the capacity is reduced by an agreed percentage for cost and sustainability purposes.

If a user attempts to launch a session and an instance is available, they will connect to their session within 2 minutes 30 seconds.

If a user attempts to launch a session with no instance capacity availability, they will not be able to connect to session. The fleet scaling policies aim to minimise the chances of this occurring, however if you encounter such issues please raise this with AVEVA Support.
