I am wondering whether the "ArcGIS desktop perpetual license" has technical support and product updates. What's happen if i don't purchase the "maintenance subscription" after I get an ArcGIS desktop perpetual license ?
You get maintenance for the first year including updates. Beyond that period, if you want upgrades and support you will need maintenance. Check with your esri distributor
But keep in mind that the "included" ArcGIS Online account and ArcPro license is annual and will most likely go away if you do not keep up on maintenance. But as Dan mentioned, this should be discussed with your customer rep or distributor for what actually works for you.
