Background
Avoid installing clients on desktops
WebLIMS for analysts
Web interface [SIMPLICA] for external customers
A id Cit i i t( ) Avoid Citrix environment(s)
‐> Varying system load
Ideal for a secure cloud [Platform ISF].

Implementation Strategy
Scripts to start up and stop application servers using Cluster Manager (CM)
f b f dd do Static set of subnet of IP addresses and names
o Minimum instances cannot be met
• Create MAC routine fires• Create_MAC_routine fires
o VM starts
o VM to join the domain scriptj p
o CM starts services
o CM manages users
o Idle VM’s
• Remove_MAC_routine fires
