You have a smooth running big data application - let’s say Hortonworks - in production. But you have lately observed the NameNode is always over 90% utilization. You want to do something about it. With ROBIN, it is as easy as adjusting the brightness of your smartphone.
Without ROBIN, you’ll have to first bring down your Hortonworks cluster for maintenance.. Recreate your NameNode configuration in another container. Copy data from the original NameNode to the new one. Manually modify the Hortonworks configuration to remove the old NameNode, followed by manually adding the new one. Then bring up your Hortonworks cluster. All this while your developers don’t have access to their Hortonworks cluster.
With ROBIN, you can simply slide a slider to increase or decrease CPU, memory and storage IOPs resources to any container, such as the under duress NameNode in this example, using one click operations. Life couldn’t be simpler! Just as easily as you can increase resources, while the application is running, you can also decrease them when the need goes down.
