Reviewing Prerequisites

Before you download and install Anypoint Flex Gateway, ensure that you review and fulfill the following prerequisites.

Permission Requirements

Running Flex Gateway requires the following permissions:

  • Manage Servers and Read Servers permissions in Runtime Manager

Your Anypoint Platform Admin can add these permissions in Access Management. See Manage Team Permissions for more information.

Your Anypoint Platform Admin can also add a Connected App with the appropriate permissions. See Connected Apps for more information.

To register Flex Gateway using a Connected App, the following scopes are required:

  • Manage Servers

  • Read Servers

  • View Organization

Software Requirements

Flex Gateway is not supported on Windows or in Docker running on Windows.

Software Requirements for Kubernetes and OpenShift Deployments

Running Flex Gateway requires:

  • A minimum of either Kubernetes 1.21 or OpenShift 4.8.

  • Ingress v1 (stable), which requires specifying apiVersion: networking.k8s.io/v1 as the API version in your configuration resources.

  • A private cloud or data center.

    Or, a cloud provider such as the following:

    • Google Kubernetes Engine (GKE)

    • Amazon Elastic Kubernetes Service (Amazon EKS)

    • Azure Kubernetes Service (AKS)

  • A minimum Helm version of 3.0.0 is required.

Software Requirements for Linux Deployments

Flex Gateway runs on the following Long Term Support (LTS) versions of Linux:

  • Amazon Linux 2023

  • CentOS 8

  • Debian (Buster, Bullseye, Bookworm)

  • Red Hat Enterprise Linux (8, 9)

  • Red Hat Enterprise Linux (8, 9) on IBM Power (ppc64le)

  • Ubuntu (Bionic, Focal, Jammy)

Flex Gateway is designed to run in cloud-native architectures. You can therefore only install one gateway instance per Linux VM. Multiple installations on a single VM are not supported.

Software Requirements for Container Deployments

Flex Gateway supports the following:

  • Docker

  • Podman

Additionally, Flex Gateway supports the following container orchestration services:

  • Amazon Elastic Container Service (Amazon ECS)

  • Azure Container Service (ACS)

  • Google Cloud Run

  • AWS Fargate

Hardware Requirements

A single Flex Gateway can support multiple backend APIs. To support more backend APIs, you can deploy multiple replicas or additional Flex Gateways.

Flex Gateway requires the following minimum hardware configuration:

  • CPU: 0.2 vCPU

  • Processor: Intel or AMD-64

  • Memory: 200 MB

Increase replica memory for higher throughput and increased performance. To support 200 APIs, each with two applied policies, at 150 transactions per second (TPS), Flex Gateway requires the following:

  • CPU: 0.2 vCPU

  • Processor: Intel or AMD-64

  • Memory: 1.5 GB

Ports, IPs, and Hostnames Allowlist Requirements

For Flex Gateway to communicate with MuleSoft-managed online Anypoint Platform APIs and services, you must add the following hostnames and ports of external resources to the allowlist:
