Label:If you have completed the development of your new MongoDB application and are now ready to deploy it into your product, you and your operations team will need to discuss some key issues:
What is the best deployment practice?
What key metrics do we need to monitor to ensure that the application meets its required service levels?
How can I determine the timing of adding shards?
