Resource Requirements

Kubernetes

Minimum Node Resources

We recommend that you have at least 3 nodes that each offer 4 CPU Cores and 16 GB of Memory per zone, and that you have at least 2 zones that your cluster is available from (to reduced the change of downtime from your Cloud provider) in order to support a majority of traffic with just the core platform.

Also, for every Destination you want supported, have an additional .5 CPU Core and 1GB Mem. available per region for every 1,000 events/sec for your peak expected traffic.

The minimum recommended size of our platform is, per zone:

  • 3x Load Balancer (.25 CPU, .5 MEM)
  • 3x Ingestors (.25 CPU, .25 MEM)
  • 2x Routers (.25 CPU, .5 MEM)
  • 1x Forwarder per Destination (.5 CPU, 1 MEM)

Calculating Scaling

The platform is set to automatically scale to meet event demand, so if you expect a large range of events or ever-increasing peaks of traffic, please leave plenty of headroom or set your cluster to autoscale.

The Load Balancer, Ingestor and Router will each autoscale roughly by one pod for every 1,000 events/sec over the minimum rate.

To calculate the amount of Forwarders you will need, take the amount of Destinations you want the platform to support and multiply it by the amount of events per second you expect at peak volume. Then, compare it against the amount of Destinations and take the higher number.

For example, if I want to support Google Analytics, Facebook Pixel, and Pinterest on my platform only, and I expect 500 events/sec. Then, I would expect 3 Forwarders.

(3*(500/1000)) = 1.5 < 3

However, supporting those 3 Destinations at 5000 events/sec, I should expect to need 15 Forwarders to handle that traffic.

(3*(5000/1000)) = 15 > 3

Supported Cloud Providers

Currently Verified Kubernetes Providers:

  • Google Cloud Platform (GCP)
  • Amazon Web Services (AWS)

Coming Soon:

  • Digital Ocean (DO)
  • Microsoft Azure

Load Balancer


Our platform will spin up an internal Load Balancer and connect it with your Cloud Provider which, depending on your Cloud Provider, may create ingress rules or spin up resources that are represented outside of Kubernetes. The only manual step that is currently required is for you to link the DNS records to Ingress instances created for the Load Balancer, as our platform takes care of the rest. Learn more about how Kubernetes leverages Ingress with Cloud Providers on their Docs.

Message Queues


We support connecting our services between different Stateful Message Queues in order to provide data durability and allow for finer connecting control for you to send data to other parts of your platform.

Our currently supported queues are:

  • Confluent Kafka
  • AWS Kafka (MSK)
  • Google PUB/SUB

Coming Soon:

  • Azure Service Bus (planned)
  • AWS Kinesis (planned)
  • NATS (investigating)
  • Pulsar (investigating)

Although we do not have current support for queues managed from within the platform, we are planning to introduce it this year. This will prevent you from having to link any externally provided services, however the total amount of resources needed will be much higher.
