Then you choose an instance size, the desired amount of RAM, storage, capacity and speed. You can opt for encrypted volumes and choose your replication factor from three to five to seven nodes. For larger apps you can opt to run a sharded cluster and select backups.
"Atlas scales with your application" Nelson said, so if you need more disk space you simply access your cluster and change the parameters.
While you cycle through these options the pricing will change on the right hand side before you decide to launch the cluster. Pricing starts at $0.026 per hour for 2 GB of memory and 10 GB of storage, depending on which region you use and scales up depending on instance sizes, storage performance, and backup schedules.
Forrester analyst and author of its Database-as-a-Service market overview Noel Yuhanna told Computerworld UK that this move to DaaS was inevitable from MongoDB and that "having a common framework, being able to scale as much as on-premise on the cloud, tooling and compatibility will be critical."
When asked if he thought this would be a good financial move for MongoDB, Yuhanna said: "It will have a big impact on income. Not overnight, but over the next few years."
Carl Olofson, research vice president at IDC said: "This is critical for [MongoDB]. If you're a database vendor and you don't have a Database-as-a-Service offering then you aren't fully engaged."
