Clean Install of TOS Aurora on GCP

Overview

This procedure is for the clean installation of TOS Aurora on Google Cloud Platform (GCP). To add a node to an existing cluster, see Adding a Node on GCP. For all other installation and upgrade options, see Installing and Upgrading.

Tufin Orchestration Suite (TOS Aurora) includes SecureTrack, SecureChange and SecureApp. You will specify the applications you want to enable, when you run the install command.

Tufin Orchestration Suite should be treated as high-risk security resource, similar to how you would treat any LDAP product (for example, Active Directory). Therefore, you should only install Tufin Orchestration Suite in an appropriately secured network and physical location, and only authorized users should be granted access to TOS products and the operating system on the server.

UDP traffic is not supported in GCP.

High Availability (HA)

High availability is supported for GCP over three availability zones, giving you a higher level of resilience and availability when deploying on this cloud platform. Note that all availability zones must be in the same region. See High availability.

Remote Collectors (RCs)

Remote collectors can be deployed on GCP. They are supported in and between different GCP regions.

Prerequisites

General Requirements

  • This procedure must be performed by an experienced Linux administrator with knowledge of network configuration.

  • If you have made a previous unsuccessful attempt to install TOS Aurora, you must uninstall and reboot before reinstalling (see Uninstalling TOS)

  • IP tables version 1.8.5 and above. IP tables must be reserved exclusively for TOS Aurora and cannot be used for any other purpose. During installation, any existing IP tables configurations will be flushed and replaced.

  • Your servers must have sufficient CPUs, disk storage and main memory for TOS Aurora to work effectively. The resources required can be categorized by system size.

    To evaluate the size of system you need, see Sizing Calculation for a Clean Install.

  • Once TOS Aurora has been installed, changing the host name or IP address will require reinstalling - see Changing IP Address/Host Names. If you want to change the host name of the node, do so before running the tos install command.

    If you need assistance, consult with your sales engineer or Tufin support.

  • Tufin Orchestration Suite should be treated as high-risk security resource, similar to how you would treat any LDAP product (for example, Active Directory). Therefore, you should only install Tufin Orchestration Suite in an appropriately secured network and physical location, and only authorized users should be granted access to TOS products and the operating system on the server.

  • If you are using NFS, your backup server needs to be running NFS 4.

Operating System Requirements

  • You must know the resources you will need - CPU cores, RAM, disk space and the load-model parameter <LOAD>, provided by your account team, based on the procedure Calculate resources - clean install.

  • All resources need to be dedicated to the TOS Aurora machine. Do not use shared CPU or memory and if the datastore is shared, the disk performance must meet the requirements at all times.

  • Do not install any software on your server before or after the deployment of TOS Aurora that is not specified in the current procedure.

  • Select a storage type of SSD. Take into consideration that TOS requires 7,500 IOPS and the throughput expected will average 250MB/s with bursts of up to 700MB/s.

  • The iptables must be 1.8.6 or later.
  • You will need to allow access to required Ports and Services.
  • Allocate a 24-bit CIDR subnet for the Kubernetes service network and a16-bit CIDR subnet for the Kubernetes pods network (10.244.0.0/16 is used by default).

    The pods and services networks must be inside the following private networks: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16. In addition, ensure that the dedicated CIDR for the service network and pods network don't overlap with:

    • Red Hat Enterprise Linux 8.10

    • The physical addresses of your TOS Aurora servers (see below)

    • Your primary VIP, Syslog VIP or external load balancer IP (see below)

    • Any other subnets communicating with TOS or with TOS nodes

  • Once TOS Aurora has been installed, changing the host name or IP address will require reinstalling - see Changing IP Address/Host Names. If you want to change the host name of the node, do so before running the tos install command.

  • You need to configure a separate partition for /opt, a separate disk for etcd, and the boot disk needs at least 300 GB of available storage. The /opt partition will contain your data, which will increase over time. Most of your available disk space should be allocated to this partition and the minimum is determined by the load model parameter (small, medium, large) provided by your account team. Minimum sizes for all partitions:

    Minimum Partition Sizes

    Boot disk

    /opt/

    (Small)*

    /opt/

    (Medium)*

    /opt/

    (Large)*

    etcd

    Central cluster / remote cluster primary data node / HA data nodes 300 GB 80 GB 170 GB 370 GB 128 GB
    Worker node (central and remote clusters) 150 GB 70 GB 70 GB 70 GB N/A

    *Small, medium and large refer to the load model parameter provided by your account team.

    We recommend allocating /opt partition all remaining disk space after you have partitioned the boot disk and etcd.

  • Select a storage type of SSD. Take into consideration that TOS requires 7,500 IOPS and the throughput expected will average 250MB/s with bursts of up to 700MB/s.

  • Secure boot must be disabled.

  • If you are using NFS, your backup server needs to be running NFS 4.
