    System Requirements

    The Spectro Cloud SaaS platform is also available as self hosted on-premise deployment. The On-Premise version is a dedicated instance of the platform hosted in customer's VMware environment. Spectro Cloud on-prem is available in two modes:

    • Quick Start Mode - A single VM deployment of the platform ideal for PoC purposes.
    • Enterprise Mode - A multi node highly available version for production purposes.

    The sections below describe the common requirements for both the deployment modes and highlight specific requirements, if any for these modes.

    vSphere Environment Prerequisites

    • General requirements
      • vCenter version : 6.7 and above
      • NTP configured on all ESXi Hosts.
    • Zone Tagging

      Zone tagging is required for dynamic storage allocation across fault domains when provisioning workloads that require persistent storage. This is required for installation of Spectro Cloud Platform itself and also useful for workloads deployed in the tenant clusters if they have persistent storage needs. Use vSphere tags on data centers (k8s-region) and compute clusters (k8s-zone) to create distinct zones in your environment.

      As an example, assume your vCenter environment includes three compute clusters, cluster-1, cluster-2, and cluster-3, that are part of datacenter dc-1. You can tag them as follows :-

      vSphere ObjectTag CategoryTag Value

      Note: The exact values for the k8s-region and k8s-zone tags can be different from the ones described in the above example, as long as they are unique.

    • Permissions

    The following permissions are required for the account used to install the platform :-

    Network Requirements

    • Outgoing access from the platform VMs to the internet either directly or via a proxy.
    • An IP Address (static or DHCP) for the quick start virtual machine (also used as an installer for enterprise version).
    • A block of 5 IP addresses reserved for enterprise cluster. One IP address for each of the three enterprise cluster VMs. An IP to be used as VIP and an additional IP reserved for rolling upgrades.
    • Interconnectivity across all the 3 VMs on all ports.
    • Connectivity from the Virtual Machines to the vCenter.
    Make sure that your Datacenter CIDR IP address does not overlap Kubernetes PodCIDR range. Kubernetes PodCIDR range settings can be changed during installation.

    Proxy Requirements

    • If a proxy is used for outgoing connections, it should support both HTTP and HTTPS traffic.

    • Connectivity to the following domains and ports should be allowed :-

    Hardware Requirements

    The following section provides the hardware requirements for Spectro Cloud Platform VMs for various capacity levels.

    • Concurrent Tenant Clusters - The number of concurrent tenant cluster provisioning or deletion requests.

    • Total Managed Clusters - The number of parallely running tenant clusters.

      The size of the tenant cluster in terms of the number of nodes or size of the nodes does not impact the capacity guidance below.

    For high availability purposes, it is recommended that you deploy the 3 VMs across 3 compute clusters.

    Best Practices

    The following steps are optional but recommended for production environments.

    • DNS Mapping

      A DNS is used to access Spectro Cloud Management Console. While the Virtual IP Address (VIP) configured on the platform can be used to access the platform, it is recommended that you reserve a DNS for this purpose and map it to the VIP after installation.

    • SMTP Settings

      Configure SMTP settings to enable the Spectro Cloud platform to send out email notifications. Email Notifications are sent out to new users when they are initially on-boarded to the platform so they can activate their accounts as well as to reset their password at a later time.

    • Trusted Certificate

      Configure your platform with a trusted CA certificates.

    • FTP Location for backups

      Configure a FTP location for platform backups and schedule daily backups.
