ScaleOut StateServer(R) is an in-memory data grid (distributed cache), which runs as a distributed software service on a set of dedicated virtual servers. It stores data objects in memory, makes them instantly accessible to networked Web or application servers, and scales to handle large workloads.
ScaleOut StateServer is an in-memory data grid (IMDG), also called a distributed cache, which runs as a distributed software service on a set of dedicated virtual servers to help scale application performance. It stores an application's data objects in memory, makes them instantly accessible to networked web or application servers, and scales to handle large workloads. Stored objects can be uniformly accessed by clients using a fully consistent storage model, and the grid enables simultaneous access by different clients to data objects stored on different grid servers. Once provisioned, ScaleOut StateServer automatically balances the amount of storage used by each server in the grid to scale throughput and maintain fast response times. As new servers running ScaleOut StateServer are provisioned, they automatically rebalance the workload to expand storage capacity and throughput. High availability is built into every feature of ScaleOut StateServer to support the needs of mission-critical applications. A comprehensive set of Java, C/C++, .NET, and REST APIs enable applications to directly access the IMDG as a key/value store using create/read/update/delete semantics. APIs also can perform a wide variety of operations, such as querying objects by their properties and handling asynchronous events. AWS instances include Standard Support for ScaleOut StateServer. Premium support packages are available directly from ScaleOut Software.
Highlights
Fast, Scalable Performance: Scales to hundreds of server instances to provide fast response times for large workloads. This gives your applications the performance and scalability they need, and the flexibility to grow or shrink the grid as required.
Ease of Use: Self-organizes by automatically combining server instances into a uniformly accessible and scalable in-memory data grid. No configuration steps are required for creating a grid membership, failover, partitioning, or client-side caching.
Powerful, Advanced Features: Includes highly automated cloud deployment, fully consistent data storage, parallel query, object browser, parallel backup/restore, object locking, object timeouts and dependencies, event handling, and much more.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Pricing is based on actual usage, with charges varying according to how much you consume. Subscriptions have no end date and may be canceled any time. Alternatively, you can pay upfront for a contract, which typically covers your anticipated usage for the contract duration. Any usage beyond contract will incur additional usage-based costs.
Additional AWS infrastructure costs may apply. Use the AWS Pricing Calculator to estimate your infrastructure costs.
You pay by the hour based on the EC2 instance type you run ScaleOut StateServer on. Each dimension maps to a specific instance size, so your rate reflects the compute and memory of the machine you choose. Options span general-purpose, compute-optimized, memory-optimized, and burstable instance families, in sizes from large up to the largest available. Because the software scales by adding servers, you can run it across a cluster and control cost by matching instance types to your workload. There is no upfront commitment; billing tracks the hours each instance runs.
Top-of-mind questions for buyers
What does one hourly unit map to, and how is it counted?
Each dimension maps to one running EC2 instance of the named type, billed per hour. Your rate reflects that instance's compute and memory. Running the software across several servers in a cluster means each instance meters its own hours, and those charges add together on your invoice.
Am I charged when an instance is stopped or powered off?
Software charges track the hours each instance runs. A fully stopped instance stops accruing hourly software fees. Underlying AWS storage or other AWS resources tied to a stopped instance may still incur AWS charges, but the ScaleOut StateServer licence meters running time only.
What happens to my cost as I add servers to scale the grid?
ScaleOut StateServer scales by adding servers to the cluster. Each added instance bills at the hourly rate for its own instance type. Total cost grows with the number and size of running instances, since the software meters each instance separately by the hour.

An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
To administer this product after deployment, if the Web Management Console was enabled, please visit http://<server>:4000/console/ (port 4000 is configurable during deployment). Alternatively, ScaleOut Software, Inc. provides ScaleOut Management Console on Windows, which can be installed separately and used for both deployment and management.
To acquire these tools on your management workstation, download and install the latest ScaleOut StateServer Remote Client installer for Linux operating systems or the ScaleOut StateServer installer for Windows systems from our Support Downloads page: http://www.scaleoutsoftware.com/support/support-downloads/. On Windows operating systems, select the Remote Client/Cloud Mgt. setup type.
Once installed, please see the ScaleOut StateServer User Guide for step-by-step instructions to manage ScaleOut StateServer on Amazon Web Services. This help file can be found in the product installation directory on your local system, or online at http://www.scaleoutsoftware.com/support/product-documentation/. On Windows systems, this help file is also available in the Start menu. Once opened, please review the sections under Deploying SOSS in the Cloud, including both the Overview and Deploying in Amazon Web Services sections.
Client applications running as a single instance or as multiple instances can connect to and make use of a deployed in-memory data grid using APIs provided by the ScaleOut StateServer Remote Client libraries. Client applications can run either within Amazon Web Services or on remote client systems. Please install the ScaleOut Remote Client libraries on all instances or servers that need to access a deployed in-memory data grid. Follow the instructions in the Product Documentation to enable a client application to dynamically connect to a named data grid within Amazon Web Services. These instructions explain how to configure the client configuration file, soss_client_params.txt, which the user stages in the ScaleOut StateServer installation folder on each client instance or remote client system prior to starting the client application.
