On-prem Technical Requirements

Minimum System Requirements

Fiddler is horizontally scalable to support the throughput requirements for enormous production use-cases. The minimum system requirements below correspond to approximately 20 million inference events monitored per day (~230 EPS) for models with around 100 features, with 90 day retention.

• Kubernetes namespace
• Compute: 96 vCPU cores
• Memory: 384Gi
• Persistent volumes: 500 Gi storage across 10 volumes
  • POSIX-compliant block storage
  • 125 MB/s recommended
  • 3,000 IOPS recommended
• Ingress Controller: Ingress-nginx or AWS/GCP/Azure Load Balancer Controller
• DNS: FQDN that resolves to an L4 or L7 load balancer/proxy that provides TLS termination

Kubernetes Cluster Requirements

As stated above, Fiddler requires a Kubernetes cluster to install into. The following outlines the requirements for this K8 cluster:

• Node Groups: 2 node groups - 1 for core Fiddler services, 1 for Clickhouse (Fiddler's event database)

• Resources:

  • Fiddler : 48 vCPUs, 192 Gi
  • Clickhouse : 64 vCPUs, 256 Gi [tagged & tainted]

• Persistent Volumes: 500 GB (minimum) / 1 TB (recommended)

• Instance Sizes

  Instance Size	AWS	Azure	GCP
  Minimum	m5.4xl	Std_D16_v3	c2d_std_16
  Recommended	m5.8xl	Std_D32_v3	c2d_std_32
