Throughput
SOME TIPS & GUIDANCE
Performance of
outbound connection
Multiple agents often
increase throughput
No throttling on

BizTalk tier does not
impact performance
Some #devops
POWERSHELL, VISIBILITY & GROUP POLICIES
• Group policy settings to allow/designate resources
• Event & audit logs available
• Agent comes with PowerShell cmdlets
