- Planning to install Teracloud® Streams
  To plan for installing Teracloud® Streams, start by reviewing the information in the planning roadmap.
  - Preparing to install Teracloud® Streams
    Use the information in this topic to plan and prepare for your Teracloud® Streams installation. The plan that you create for your environment determines your tasks and choices throughout the installation process.
  - Considerations for environments with multiple resources
    Review these options and requirements for Teracloud® Streams environments before you install the product.
  - Hardware requirements
    Before you install Teracloud® Streams, ensure that the target system satisfies the minimum hardware requirements.
  - Software requirements
    Before you install Teracloud® Streams, run the dependency checker script to verify that the target system satisfies the product software requirements.
  - Domain controller service options
    A domain controller service runs on every resource in a Teracloud® Streams domain and manages all of the other services on that resource. You can set up the domain controller service as a registered Linux™ system service or an unregistered service.
  - Firewall configuration guidelines
    If firewall usage is required, the preferred configuration is to set up a firewall at the perimeter of the Teracloud® Streams cluster to restrict network access to resources in the cluster but not communication between the resources. When any communication passes through a firewall, latency is introduced. These guidelines apply to clients that are in the Teracloud Streams cluster as well as clients that are external to the cluster.
  - Linux ulimit configuration guidelines
    The default Linux™ user limit (ulimit) values might be too small for some Teracloud® Streams environments. Use these guidelines to ensure that your ulimit settings are sufficient for Teracloud Streams.
  - Name resolution requirements for resources
    All resources must satisfy the product network configuration requirements or Teracloud® Streams fails to start on the resource.
