Interesting recipe for moving from dedicated servers to the cloud with MongoDB:
You could bring up the new instances on EC2 and add them to the set. Once they were synced, set the priorities of the
dedicated servers to 0 (so they won’t become master), make sure one of the EC2 servers becomes master, and then take the old servers offline.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
