2.4 The Upscaling and Bursting Process
This is the process as implemented by the Upscale and burst a vApp workflow, which allows the use of a mix of fixed, scale everything, and intelligent scaling modes:
Fixed mode
– T
he workflow allows you to scale
a given tier without changing the other tiers.Scale e
verything mode
– The workflow instantiates
a new vApp when reaching the configured threshold of the maximum number of virtual machines
for a given tier. If the values for maximum instances and minimum
instances are equal,
then the workflow scales
everything for every upscale. Intelligent mode
– The workflow
can scale individual tiers,
with some limitations. S
caling the application or database tier without changing the workflows requires the vApp to be designed so
that the given tier is configured to automatically update and use a new virtual machine
when it is added.
