RavenDB 4.0 is going to have a completely free community edition that you could use to run production systems. We do this with the expectation that users will go with the community edition and either will be happy there or upgrade at some point to the commercial editions.

As part of the restructuring we are doing, we intend to also significantly simplify the support model. Our current support model is per RavenDB instance with professional support costing 2,000$ per instance and production (24/7) support costing 6,000$. We got a lot of feedback on this being complex to work with. In particular, the per instance cost meant that operations would need to talk to us during redeployments in order to maintain coverage of all their RavenDB instances.

As part of the Great Simplification we do in 4.0 we also want to tackle the issue of support. As a result, with the rollout of the RavenDB 4.0 RC we are going to move to flat support costs.

• Professional Support will cost 15% of the license cost and give you access to our support engineers with a guaranteed next business day response time.
• Production Support will cost 30% of the license cost and give you access to the core team members with 24/7 availability.

This is a significant reduction in price, because we are trying to encourage more people to get support and our previous approach was unbalanced.

The community support will continue to be offered, obviously, but we have no SLA around issues raised there.

The commercial support options will only be available for the Professional and Enterprise editions.

Here is how the costs change between RavenDB 3.x and RavenDB 4.5 for production support:

	RavenDB 3.x	RavenDB 4.0	Savings
Standard + Production Support	6,698$	5,843$	15% reduction
Enterprise 4 Cores + Production Support	9,152$	6,864$	33% reduction
