Hi Community, My company builds Stock Trading Systems and we are using Cloudstack for hosting the services we need for distributing Live Market Data Prices to around 100,000 Concurrent Users.
Id like to know, has anyone hit any performance/throughput limit with Cloudstack before? And if so, what was your traffic like? What was your scenario? How did you overcome it? Im asking this because if there was a limit, we’d like to know early on and see how to avoid it. This is our setup, Per Datacenter. # 1 VPC with 2 Subnet # Virtual Router System Offering set at 4Core,4GB memory (Hyperthreaded, no oversubscription) # Virtual Router has redundancy turned off # Data Source -> Autoscale Group 1 (Around 20 VMs) -> Autoscale Group 2 (Around 40 VMs) -> Autoscale Group 3 (Around 20 VMs) -> End Users via APIs # Each VM is around 16 Core, 32GB (Hyperthreaded, no oversubscription) # Because we are using VPCs, I believe Cloudstack only deploys 1 Virtual Router that is used for all subnets, load balancing, autoscaling, routing, NAT, Private Gateway etc. # In our current On Prem Setup, our internet uplink can peak at 5Gb, Per Datacenter. (We assume the traffic is the same in Cloud). # Mainly distributing data via RestAPIs and Websocket APIs Regards, Bryan
