Architecture best practice for NAV integration

(0) ShareShare
ReportReport
Posted on by MZ_980 103

I have a requirement where our NAV instance is going to be the system of record and we'll have Dynamics CRM, a canvas app, a portal and a web site connect to it.  I would like to create a service layer between NAV and the apps for security reasons and in case of the NAV endpoints changing I would only have to change the endpoints in the service layer and not in the apps.  Is this a common practice or is this unnecessary?  If you have any other suggestions, please let me know.

Thanks!

    Are you referring to something more than the required 3 tier architecture? It is common to have more than 1 service tier for accessing the main DB. Generally you would have them on different vm’s or boxes. Same vm or box is fine but they have the same server dependency that way.

    Hi Josh.  Thanks for replying.  I'm not sure of the reasoning for having multiple service layers.  Wouldn't that negate the advantage of having a single place to manage API access?

    Multiple service tiers enables load balancing. You could use one for the api and the other for user logins. Just an option not fundamental

    Makes sense.  Can you recommend some websites that would have this architecture diagram?

    Hello,

    I am unaware of specific Microsoft documentation but some partners did publish about it; e.g.:

    www.tecman.co.uk/.../275-the-benefits-of-an-azure-load-balancer-with-dynamics-365-business-central

    Thanks.
