Take the 2-minute tour ×  Openshift pricing model states that
you can have 3 gears in the free tier.  Other services normally
explain their free tiers in number of "web workers" that you can
have.  What is an openshift's gear exactly then? I know that you
can install a different programming environment in each gear,
but if you install the same one (let's say: ruby) in all your 3
free-tier gears, do you have 3 web-workers running at the same
time? (As in: improving scalability and redundancy; are they
load-balanced?)  share|improve this question add comment  2
Answers  Gears can be thought of as equivalents to "web workers"
however gears is better described as a unit (collection of
resources).  In the OpenShift free tier you only have small
gears (1GB mem, 1GB HDD, etc.) So the small gear is a unit of
resources that you have for you to use.   If you want an
application that scales (using the free tier), it can be done
however some find it difficult as DB often get their own GEAR,
as well as the LB (HA-Proxy),
