They are many, like Amazon Aurora database, which is a MySQL and PostgreSQL-compatible relational database, which gives it the strengths and weaknesses of SQL databases. Also Amazon DynamoDB, which is a key-value noSQL database, again, which gives it the strengths and weaknesses of SQL databases.
- What’s the difference between a FIFO and a standard queue?
“Standard queues provide at-least-once delivery, which means that each message is delivered at least once.
FIFO queues provide exactly-once processing, which means that each message is delivered once and remains available until a consumer processes it and deletes it. Duplicates are not introduced into the queue.”
From amazons website.
- How can the server be assured a message was properly received?
By waiting for a packet from the client that tells the server that the message was actually delivered.
