MMCloud User Guide
MMCloud Architecture
MMCloud has several components that interact with cloud services to ensure mobility for submitted jobs so that, for example, jobs run to completion on Spot Instances.
Cloud Service Providers
To use MMCloud, you need an account with a Cloud Service Provider.
Containers provide a standardized and repeatable way to package, deploy, and manage applications in the cloud.
Job Schedulers and Workflow Management Systems
MMCloud includes a job scheduler for running batch jobs in the cloud.
Obtaining an OpCenter License
Deploying OpCenter in AWS
Deploying OpCenter in Google Cloud
Using the OpCenter Web Interface
The OpCenter provides a web interface to activate the license and to submit and manage jobs.
Using the MMCloud CLI
Submitting a "Hello World" Job Using the Web Interface
The web interface provides a form that you complete to submit a job.
Submitting a "Hello World" Job Using the CLI
Use the MMCloud CLI to submit a job.
Running a Batch Job
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.
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.
Support and Troubleshooting
SpotSurfer removes the risk of running stateful applications on Spot Instances while reducing costs significantly.
When enabled, WaveRider allows OpCenter to optimize cloud resources by moving jobs as the resource demands change.
SurfZone is a cost management feature that helps limit the amount spent on cloud computing each month.
Gateway Service
The gateway service provides a reverse proxy so that a job can migrate from one host to another without interrupting client connections.
WaveWatcher displays real-time resource utilization graphs on a per job basis.
CLI Command Reference
Use the float CLI commands to interact with the OpCenter; for example, to submit and manage jobs.
OpCenter Configuration Parameters
Configurable parameters control the behavior of the OpCenter.
