Benefits of having MID servers on AWS vs On-Prem. Which will be better and why ?

Right now we have MID servers on both AWS Cloud and On-Prem but I want to understand the benefits of having MID server on a cloud infrastructure compared to On-Prem. Cloud is good for applications but is it good for MID servers ?

Hi Avro,

I was expecting that you are having probably mixed environment and because of that you asked this question. From my perspective I would stick to main idea which is similar to this:

MID server is extension of ServiceNow to connect to local resources where you are not able to connect directly from cloud where ServiceNow SaaS is hosted. Even not mentioning VPN which is another option but used in very specific situations.

Therefore my suggestion would be to place MID server close to devices which you are connecting to and not move them far away and have VPN between your MID server cloud and your intrnal network, unless you have many MID servers hosted in public cloud and specific usage of that.

Advantage of scaling and bursting performance you would probably use in case you are running performance extensive tasks on MID server and then answer is YES = use cloud and flexible scaling and elasticity.

On other side when you using it for integrations (eg. LDAP, ODBC, REST or SOAP) then it is not so crucial for CPU performance as it mostly forward messages which retrieves via ECC queue. In that case I would go more for easier and safer networking solution and if you are still interested in elasticity and scaling on premise I would suggest you to use MID server running in docker container which gives you much more flexibility even onsite.

Did I answer your question? Was it helpful or you need more help. If you ask generic question I can answer also in generic mode. Please let me know if interested in MID server running on premise in Linux Docker container. Can share that as well.

Kind regards,

David

The Management, Instrumentation, and Discovery (MID) Server is a Java application that runs as a Windows service or UNIX daemon on a server in your local network. The MID Server facilitates communication and the movement of data between a ServiceNow instance and external applications, data sources, and services.
