Single-Node Deployments

In single-node deployments, the Tamr Core platform is deployed on a single server.

Tamr Core must be deployed on a dedicated server. Only Tamr Core and its dependencies can run on this server. This requirement applies to on-premise and cloud-native deployments, where Tamr Core is deployed on a physical server or a virtual machine (VM) environment.

Tamr does not support deployments in which Tamr Core is installed on a server that also runs other applications.

importantimportant Important: Tamr Core cannot operate on disks that are more than 80% full. With release v2022.001.0, Tamr Core validation scripts verify that at least 20% disk space is available.

Sizing Guidelines

In general, Tamr Core performance scales linearly with computational resources. The specifications that follow use the following "t-shirt" sizes:

  • Large: 1M to 10M records
  • Medium: 100k to 1M records
  • Small: up to 100k records

For larger volumes, Tamr offers cloud-native deployments that can be scaled to meet your needs.

Specifications for On-Premise Deployments

Tamr Core can run entirely on a single server.

Deployment Resource Specification
Large CPU 32 cores
Memory 256 GB
Disk 5TB SSD
Medium CPU 16 cores
Memory 128 GB
Disk 2TB SSD
Small (minimum) CPU 8 cores
Memory 64 GB
Disk 1TB SSD

XFS is the recommended file system for all Tamr Core deployments.

PostgreSQL Deployment Requirements

For single-node Azure and GCP deployments, Tamr only supports installing Postgres on the same server as Tamr Core.

For single-node AWS deployments, Tamr recommends installing Postgres on the same server as Tamr Core. If required, you can install Postgres on a separate AWS RDS Postgres instance using the Tamr AWS RDS Terraform module. If deploying via RDS, you must follow the terraform module instructions in Deploying Tamr on AWS and ensure that there is a route between the Tamr Core VM and the RDS network.

NGINX Deployment Requirements

NGINX is a reverse proxy server configured to allow clients to access Tamr Core securely over HTTPS, and is a critical component in the Tamr Core network security layer. For more information, see Requirements for NGINX version support, Installing NGINX, and Configuring HTTPS.

For non-production environments, configuring a firewall (below), NGINX, and HTTPS is strongly recommended but not required.

importantimportant Important: If you do not configure a firewall, NGINX, and HTTPS in a non-production deployment, all users on the network will have access to the data. Use a unique password for this deployment.

Firewall Requirements

For cloud deployments on AWS, Azure, or Google Cloud Platform, use the firewall provided by the cloud provider. This allows you to have control over and visibility into the firewall from the cloud console. See the following:

For on-premise VM deployments, use the firewall provided by the operating system.

Firewall configuration requirements:

  • Allow only internal access to Tamr Core default port 9100 (via TCP).
  • Open port 443 for HTTPS, with a restrictive IP range that you specify using IPv4 addresses in CIDR notation, such as 1.2.3.4/32.
    Note: If you plan to forward HTTP traffic to HTTPS, also open port 80.

Included Services and Ports

Securing Tamr Core Ports

When configuring the firewall, only open port 443 and any ports required by your system administrators to outside traffic. Tamr Core default port 9100 should be accessible ONLY inside the firewall.

Note: If you plan to forward HTTP traffic to HTTPS, also open port 80.

Tamr Core Microservices

A single-node deployment provides access to these microservices at the following default ports. In addition, they are available via a proxy at the default Tamr Core port (TCP 9100).

Optional administrative ports can be found at each of the above ports +1. For example, an administrative port for 9020 is found at 9021. They include endpoints for operational information and ensure that a heavy user request load cannot prevent administrative requests from getting through.
