MongoDB Dynamic Scaling

The ability to scale dynamically is one of the most important requirements for your MongoDB hosting deployment in the cloud, as you want to be able to scale up your deployment with minimal impact.

At ScaleGrid, we allow you to perform a dynamic, in-place scale to scale up your MongoDB clusters to any instance type or size through our Dedicated and BYOC DBaaS plans.

1. Login to the ScaleGrid console, and visit your MongoDB cluster details page.
2. Click on the 'Scale' icon under the 'Overview' tab.
3. Select the new size that you want to scale to.
4. Review the configuration details of your scale operation directly below, then click the 'Scale' button.

Your MongoDB Cluster will now dynamically scale

From that point on, ScaleGrid takes over and provides a dynamic, in-place scale. This is implemented as a rolling operation where we perform the following tasks to scale your deployment:

• Take down one node at a time
• Update the instance type
• Update the disk size
• Update the disk IOPS (if necessary)
• Bring the node back up
• Wait for it to sync up
• Repeat to dynamically scale all nodes

So in this way, as a rolling operation, you can dynamically scale your MongoDB deployment online. The only impact on your application is that you will see a failover of the master from one node to another.
