I can see Gemfire is available for download at https://network.pivotal.io/products/pivotal-gemfire#/releases/2804/file_groups/500.
Will I have to pay once I download and install it? Can I use it without restrictions and without professional support?
What features does it have in addition to what is provided in the open source Apache Geode?
What is the license cost if I have to purchase Pivotal Gemfire?
