Are you trying to decide if you should use MongoDB or DocumentDB? With the recent controversy surrounding licensing with MongoDB, it can be confusing to decide which option is right for your company or project. Amazon decided the core MongoDB code is challenging to scale while remaining highly available. Amazon wrote their implementation, which is compatible with the Apache 2.0 open source MongoDB 3.6 API. MongoDB, Inc. has also recently changed their license to make future imitations more difficult. To do this, they created an entirely new license called the Server Side Public License.
