Aspera Transfer CLUSTER Manager
Aspera's award winning Aspera Transfer Cluster Manager (ATCM) is an essential management system for provisioning, monitoring, managing and auto-scaling of Aspera transfer clusters. ATCM provides Autoscale capabilities that allow the Aspera transfer nodes to self-scale in today's dynamic cloud environments. The technology is used by the Aspera Transfer Service and is available for customers using Aspera On Demand. The core capabilities are an autoscale cluster manager service for elastic autoscaling of transfer hosts and client load balancing and automatic cluster configuration, the new node/v4 multi-tenant secure access key system, and a new cluster management UI for managing policies and reporting on transfers across the cluster. ATCM supports Aspera On Demand clusters on SoftLayer, AWS and Azure.
Administrators have a comfortable web UI and corresponding set of APIs for all necessary cluster management tasks. Provisioning can be achieved using customizable templates, access keys can be created for Amazon, Azure, Azure SAS, IBM COS, and Google. Advanced storage features such as AWS Infrequent access, AWS Reduced Redundancy, AWS Server side encryption at rest AES 256 or KMS, Azure Page BLOB, Block Blob and Cool storage are all supported. ATCM works in tandem with ScaleKV, Aspera's distributed and scalable in memory data store for aggregating all transfer authorization, management and reporting data across the cluster.
The Autoscale functionality is complemented by ScaleKV, the scale out data store for distributed, high throughput collection, aggregation and reporting of all transfer performance and file details across the Autoscale cluster.
The service provides automatic start/stop of transfer server instances, automatic balancing of client requests across available instances, monitoring and restart of all critical services on the server instances, and configurable service levels to manage maximum transfer load per instance, available idle instances for "burst", and automatic decommissioning of unused instances.
FAST TRANSFERS OF VERY LARGE FILES AND DATA SETS TO/FROM THE CLOUD
Moving huge files and data sets or massive file repositories globally to and from your cloud infrastructure can be very challenging. Traditional transfer software technologies are slow and unreliable, and shipping physical disk storage is time consuming, expensive and exposes your data to unnecessary security risks. Using the web interface, the Aspera Transfer Cluster Manager enables you to set user-defined policies that automatically manage the provisioning and deprovisioning of servers in a cluster to quickly accommodate large spikes and drops in transfer loads.
OPTIMIZED TO MEET SLAS AND CUT COSTS
The ATCM manages transfer throughput SLAs and compute/bandwidth costs with elastic scaling. The service is part of the Aspera transfer server software stack, and automatically manages the number of server instances needed to support client transfer demands based on user-defined policies and automatically manages the number of nodes in use and booted up in reserve but idle.
HIGH AVAILABILITY AND LOAD BALANCING
As transfer loads increase and decrease, nodes are moved from idle to available for client requests, and from available to highly utilized and back again based on user-defined load metrics such as tolerances for low and high transfer throughput and online burst capacity. If the minimum number of available nodes drops below the user-defined threshold, the cluster manager boots up new nodes automatically, and then brings them back down when they are no longer needed. Similarly, unavailable/down nodes are automatically detected and restarted, and client requests are re-pointed to healthy nodes.
COMPATIBLE ON ALL MAJOR CLOUDS
Works in conjunction with Aspera Direct-to-Cloud storage - infrastructure independent. All of the Autoscale capabilities are implemented in the Aspera software and thus are portable across cloud providers. Includes support for AWS, SoftLayer, and Azure autoscale clusters.
SCALEABLE, ROBUST TRANSFER MANAGEMENT & REPORTING
All transfer initiation and management scales across the cluster with ScaleKV technology, a new Aspera created scale out data store for distributed, high throughput collection, aggregation and reporting of all transfer performance and file details across the autoscale cluster, and transfer initiation across the cluster.
CLUSTER API CAPABILITIES
Key API capabilities provided by the Cluster:
- Query transfer status across the cluster - The new transfer API (node/v4) returns transfer progress and details across the entire cluster. Transfer statistics are automatically sharded across the memory of all nodes in the cluster, keeping up with very high transfer rates and number of sessions.
- Transfer using all nodes in the Cluster - The new transfer API (node/v4) allows third party applications to initiate transfers that use multiple / all nodes in the cluster for throughput beyond the capability of a single node, and automatic failover and fault tolerance.
- Securely Support Multiple Tenants - New mulit-tenant secure access key system (node/v4) allows Aspera administrators of applications such as Files, faspex and Shares to securely support multiple tenants on the same cluster with private access to separate cloud storage and transfer reporting.
- Report transfer status and usage by Tenant - The transfer API (node/v4) allows queries of transfer history by access key to securely report history and usage by access key tenant. (Aspera On Demand usage reporting is being enhanced with usage by access key.)
CLUSTER MANAGEMENT UI
A New web-based cluster management UI manages access keys, cluster configuration including Autoscale policy and in memory data store for transfer statistics.
Key features include:
- Configuring auto-scale policies and transfer node (aspera.conf) templates and automatically implementing these on new and running clusters
- Configuring and installing SSL certificates for Aspera nodes
- Enhanced service monitoring and management to monitor and restart key Aspera services and automatically decommission failed nodes
- Live cluster upgrade allowing a cluster manager to migrate a live running cluster to a new machine image version without disrupting running transfers.
- Enhanced resilience to failure including ability to backup and restore the cluster state, options to back the main state store on a clustered database (AWS RDS, Azure ClearDB), and in failure recovery, the ability to launch new node images with configuration from the backup.
- Easy duplication of cluster template configurations through the UI
- Create access keys for all supported Aspera transfer cluster platforms (AWS, Softlayer, Azure in 3.7)
- Health monitoring and restart of all critical Aspera services on individual instances.
- Updating of aspera.conf file across all nodes in the cluster.
- View all active and completed transfers with filters by access key
The Aspera Transfer Cluster Manager is core technolgy in the Aspera Transfer Service and is available for customer-managed deployment as an Aspera on Demand subscription with pricing based on a committed amount of data transferred. The ATCM is packaged as a virtual machine image and can provision clusters of Aspera servers leveraging a deployment template. The clusters are deployed in a virtual private cloud (VPC).

What's New with Autoscale Cluster Manager
The recent releases of the Autoscale Cluster Manager and cluster nodes include the following Transfer Performance Enhancements for Amazon:
