‫Now let's talk about DocumentDB.
‫So the same way we had Aurora as the way for AWS
‫to implement a sort of big cloud native version
‫of PostgresSQL and MySQL,
‫we have DocumentDB, which is an Aurora version for MongoDB.
‫So MongoDB, if you don't know,
‫that's the logo on the top right corner of your screen.
‫It is another NoSQL database,
‫and you need to remember this for the exam.
‫So DocumentDB is a NoSQL database,
‫and it's based on top of the MongoDB technology.
‫So it's compatible with MongoDB.
‫So MongoDB is used to store query and index JSON data,
‫and you have the same similar deployment concept
‫as Aurora with DocumentDB.
‫So that means it's a fully managed database.
‫It's highly available.
‫Data is replicated across three availability zones,
‫and the storage will grow automatically
‫in increments of 10 gigabytes
‫up to 64 terabytes of storage, all of this, okay?
‫And DocumentDB has been engineered so it's can scale
‫to workloads with millions of requests per second.
‫So at the exam, if you see anything related to MongoDB,
‫think DocumentDB, or if you see anything related
‫to NoSQL databases, think DocumentDB and also DynamoDB.
‫That's it for this lecture.
‫I hope you liked it,
‫and I will see you in the next lecture.
