MID-less vs MID ACC configuration

My customer wants to deploy ACC-V to 11,000 End User Devices and because those devices are air-gapped i.e. do not have access to an on-prem MID Server we are thinking of a MID-Less ACC installation.   What I need to know is what are the pros and cons of MID-Less vs using MIDs (with a public facing IPs)?  Are there performance concerns since the loadbalancing would be performed by ServiceNow's Loadbalancing in a MID-Less configuration vs MID Server Loadbalancing.   Also, what other concerns or considerations such as security and deployment would there be?   Any docs, best practices or helpful suggestions will be much appreciated.

Hi Buddy,

First, one key point: MID-less ACC still requires outbound HTTPS to ServiceNow. If the devices are truly air-gapped (no outbound access at all), MID-less won’t work and you’d need an offline collection/import approach instead.

If the devices can reach the internet via a proxy, then MID-less is a solid option.

MID-less ACC – Pros

  • No MID servers to deploy or maintain (big win at 11k devices)

  • No internet-facing infrastructure on your side

  • ServiceNow handles scaling and availability

MID-less ACC – Cons

  • Requires outbound HTTPS and proxy/cert setup

  • Some troubleshooting shifts to network/security teams

  • Pilot first to confirm ACC-V coverage

MID-based ACC (public MIDs)

  • More control, but you’re exposing MIDs to the internet

  • Higher security, patching, and operational overhead

  • Load balancing and scaling become your responsibility

Performance

  • Usually not a major issue either way

  • Bigger concerns are agent frequency, data volume, and proxy capacity

Essentially:
If endpoints have any outbound access, MID-less is usually simpler and safer.
If they have no outbound access, neither MID-less nor public MIDs will work — offline collection is the only option.
