  The Memory Machine Cloud web interface and CLI have a rich set of options that allow you to customize the container runtime environment.
- Configuring Data Volumes
  A job that generates file system I/O requires a definition for one or more file systems.
- Controlling Virtual Machine Types
  The selection of virtual machine types can be restricted by using an allow list or a deny list (or both).
- Service Templates
  Service templates simplify the procedure for submitting jobs that include many options.
- Filters
  Use filters to limit a command to a subset of all jobs, hosts, or gateways.
- Handling Job Failures
  The error policy determines how job failures are handled.
- Securing MMCloud
- Upgrading OpCenter
  If a later version of OpCenter software is available, an OpCenter instance can be upgraded even if jobs are currently running.

Working with OpCenter

Introduction

The OpCenter is the control point for MMCloud. All interactions with the OpCenter use the web interface, the Web CLI shell, or float CLI commands in a terminal session. The web interface also provides a dashboard and graphical displays of resource utilization.

Although most features can be invoked using any of the three methods, the CLI in a terminal session offers the most functionality. For example, you must use the CLI in a terminal session to upgrade the OpCenter software (software upgrades are not possible using the other two methods).

Most users only run a subset of the float CLI commands in their everyday use of OpCenter for running workloads. A detailed float command reference is available; this section provides summary descriptions for common use cases.
