What is the minimum period I can obtain Enterprise On-ramp or Enterprise Support?

I apologize, but I don't have specific information about the minimum commitment period for AWS Enterprise On-Ramp or Enterprise Support based on the provided sources. The sources do not mention any details about minimum contract lengths or the ability to obtain these support plans for short-term periods like 1 to 3 months.

AWS Enterprise On-Ramp and Enterprise Support are typically designed for businesses with ongoing, critical workloads in AWS, suggesting they are usually longer-term commitments. However, without explicit information about minimum periods or short-term options, I cannot definitively state whether a 1 to 3 month period is possible or if there's an annual commitment requirement.

For the most accurate and up-to-date information regarding the minimum period and flexibility of these support plans, I recommend contacting AWS directly or speaking with an AWS sales representative. They would be able to provide you with the specific details about commitment periods and any potential options for shorter-term engagements that might be available for your particular situation.
