Based on another mission critical application CCRC , which required high throughput & to scale linearly and support upto 2.5 million hits per day (check with CCRC team), we decided to put it on Physical C-Series servers with local storage (SSD) after comparing with the throughput from Openstack platform, . Here we have done JBOD config for better I/O throughput.
The major difference here is the storage as well as more compute (CPU & Memory) resource. With Local SSD & huge CPU x Memory, we have achieved very good application performance.
But it seems we were not utilizing the entire resource wrt CPU & Memory. So we came up with a new architecture which I am going to share.
This Arch covers the complete Active/Active database Multi DC setup.
GSS will direct the connections
