5/4/2020: New Feature
Instant Cloud now support end-to-end encryption and disk encryption on both AWS and Azure. Please find the updated security document on the website.
3/13/2020: New Features
Notifications can be automatically generated when a specific situation may require your attention:
- a license remaining credit is low,
- a license is about to expire,
- or a machine is running out of memory (usage over 90%).
Notifications are enabled by default for Bronze, Silver, and Gold licenses with default thresholds. You may need to review the settings of your licenses to enable or disable the notifications and adjust the thresholds according to your needs. In the license panel, you can open the detail page and edit the notification settings in the notifications tab. Notifications can be enabled or disabled for each license. You can also provide several thresholds to trigger notifications. Please click the link here to learn more.
2/18/2020: New Features
Support of Gurobi Optimizer 9.0.1
Version 9.0.1 is now supported in addtion to 8.0 and 8.1. In addition, we have recently released a new credit notification feature for our Gurobi Instant Cloud users. With this new feature, you will receive automatically generated notifications, via the notification panel or email, whenever your current license credit drops below a pre-set threshold. The purpose of these notifications is to alert you to the fact that your credit is low – so that you can take the necessary actions to ensure that your licenses are always credited with sufficient funds and thereby avoid service disruptions.
11/25/2019: New Features
Support of Gurobi Optimizer 9.0
The version 9.0 is now supported in addition to 8.0 and 8.1. The client versions 7.0 and 7.5 are deprecated and will be removed in January 2020. We encourage all clients to upgrade to 8.1 or 9.0 versions. If your pools are currently using version 8.x, it will automatically support 9.0. Clients can also mix 8.x and 9.0 with the same pool, so that you can upgrade them progressively.
1/11/2019: New Features
The statements are now available directly in the Cloud Manager with a summary and a cost breakdown chart by pool, machine type or region. The machine usage provides more details with sorting and filtering. The statements can be downloaded as a CSV or HTML file. A REST API endpoint is also provided to retrieve the data programmatically.
10/22/2018: New Features
Support of Gurobi Optimizer 8.1
The version 8.1 is now supported in addition to 8.0.1. Clients can start upgrading to the latest version.

4/24/2018: New Features for the v8 Engine Only
Better Security and Easier Integration with HTTPS
With the v8 engine, all the communications between the clients and the Gurobi Instant Cloud are using the HTTPS protocol. This means that your communications are secured and encrypted using standard internet protocols. In addition, Gurobi servers enforce the latest encryption policies (TLS v1.2 and above only). For better security, the dedicated machines started by Instant Cloud on your behalf cannot be accessed directly, and all communications must transit through a secured and highly-available region router acting as a reverse proxy. This also facilitates the integration with clients as only the standard HTTPS protocol and standard port 443 need to be open if a firewall is in place. For customers who have used versions v6.x and v7.x, the new v8 engine will simplify their network integration, as there is no need to open ports 61000 to 65000 anymore. Also, please note that the pool fixed IP feature of v6.x and v7.x engines is not available for v8 as we have replaced the protocols by internet standards.
Active Job List
The v8 engine now provides visibility into the jobs running on the machines. The Instant Cloud Manager has a new menu option to list the jobs currently running or queued on all active machines and pools. The list also contains recently ended jobs with a status:
- completed: the job ended successfully
- aborted: the job was aborted
- disconnected: the connection with the client was lost because the client terminated or experienced a network issue
- idle timeout: the client was still connected but was idle for too long (see IdleJobTimeout)
- failed: the job running on the server experienced an unexpected problem and failed, for example the job went out of memory.
Note that when a machine is terminated, the job executed on this machine will disappear from this list. If you need to keep visibility on all executed jobs, see the Job History feature below. It is also possible to select jobs and abort them.
Active Job Dashboard
From the active job list, the detailed job dashboard can de displayed. The job dashboard provides different views about a given job in order to let an optimization expert monitor the job execution:
- general job information and status
- current KPIs of the model and the algorithm
- changed parameters passed to the job
- charts showing the progress of the optimization
- live engine log
While the active job list provides a view of jobs currently queued, running or recently ended, the job history provides a persistent list of ended jobs. The new job history menu option lets you browse and filter these jobs. The engine log can also be downloaded. When using this feature, the job metadata and the engine logs are stored on the Instant Cloud secured servers for a maximum of 90 days. This feature can be disabled on selected pools or machines in the options panel.
It is now possible to scale up or down your pools using the Instant Cloud Manager or the REST API. A pool defines a number of compute servers that is actually the minimum number of servers. So when a client starts a pool, the pool will be ready when this number of servers is ready. Then, you can scale up by requesting additional servers to be added to the pool. When servers are added, they automatically join the cluster of compute servers of the pool and start processing new jobs or jobs already queued in existing servers. The pool will scale down automatically by using the existing idle shutdown parameter. This means that any server being idle for this time limit will be terminated, up to completely terminate the pool. The pool can also be explicitly scaled down by reducing the number of servers. In this case, if a machine must be stopped but it is already running a job, it will be moved into a draining mode where new jobs will not be processed while running ones will be processed normally. When these jobs have completed, the machine will be automatically terminated. For better monitoring, the pool view displays the number of machines that are starting, stopping and the ones that are ready.
The machines are now reporting the current CPU and memory usage. These metrics are displayed in the machine view.
Idle Job Timeout
A parameter has been added to specify the duration limit after which the job will auto-terminate when there is no command sent to the server. This is useful to avoid using resources when some clients may leave their connections open (for example in an interactive python shell) while not being active. Clients can set this timeout using the CSIDLETIMEOUT parameter or using the IDLETIMEOUT property in the license file. The default value is 30 minutes. The pool or machine option can be used to set a larger timeout globally that will override the client default.
Extended REST API
The REST API has several new endpoints to support the monitoring of active jobs, the access to job history and the management of pool scaling. See the REST API reference documentation for more details.
4/24/2018: Global Updates
In order to provide better support on heavily used regions, we have decided to focus our resources on 5 regions:
- us-east-1 (N. Virginia)
- us-west-1 (N. California)
- eu-central-1 (Frankfurt)
- ap-northeast-1 (Tokyo)
- ap-southeast-2 (Sydney)
As a consequence, we are discontinuing the support of 3 regions and if you had pools using these regions, they will be automatically moved to the nearest one as follows:
- eu-west-1 (Ireland) is replaced by eu-central-1 (Frankfurt)
- us-west-2 (Oregon) is replaced by us-west-1 (N. California)
- ap-southeast-1 (Singapore) is replaced by ap-southeast-2 (Sydney)
Supported Engine Versions
As we are now supporting the new v8 engine, we have removed the support of v6.0 and v6.5 in Instant Cloud. Our policy is to support the last two major versions, namely v8 and v7.x. If you had pools and preferences using these versions, they will be automatically upgraded to v7.0.
7/12/2017: Added Support for the v7.5 Engine
The new v7.5 engine can now be selected in the dropdown menu of the engine versions of your pools and machines. Note that the version of the client and the machines or pools must match. If you had existing pools, they will still use the current version. When you are ready to use the v7.5, you will need to manually update the version of your pools to match the client so that you can upgrade at your own pace.
