Each new product license comes with 30-day free maintenance and support. If you would like to continue to benefit from priority technical support and get access to all new version releases after this initial 30-day period, you can purchas an AMS (Annual Maintenance Subscription. The AMS is usually valid for 12 months from the original product license purchase date, even if purchased later.
