High availability provides access to critical business applications and data in the event of a service disruption.
This blog aims to create a knowledge base for HA in Aspera.
Aspera's Core Technology
- Aspera utilizes its patented FASP (Fast, Adaptive, and Secure Protocol) technology to achieve unprecedented speeds in file transfers. FASP overcomes the limitations of traditional transfer protocols by optimizing data transfer based on network conditions, adapting to fluctuations in bandwidth, and ensuring security through encryption.
- In the dynamic landscape of data-intensive workflows, organizations are constantly seeking solutions that provide high speed and reliability in file transfers. Aspera, a groundbreaking file transfer technology developed by IBM, has emerged as a leader in this space, offering a High Availability, High-Speed Transfer Server that addresses the evolving needs of data-driven enterprises. This blog post will delve into the key features and benefits that make Aspera a standout choice for organizations seeking a cutting-edge file transfer solution.
Understanding High Availability in Aspera
High availability refers to a system's ability to remain operational and accessible, even in the face of hardware failures, software issues, or unexpected disruptions. Aspera's commitment to high availability ensures that its users experience minimal downtime, allowing for continuous data transfer operations critical for today's dynamic business environments.
How Aspera HSTS High Availability Cluster works
Companies using Aspera's solutions often include those in media and entertainment, healthcare, finance, research, and other industries with high-volume data transfer needs.
- We will have 3 HSTS servers with common shared storage, we would select any of the HSTS servers that would act as primary and the rest as the replicas.
- We could consider one HSTS server as a master node that contains all the details of the HSTS servers like the primary server and replicated servers.
- HSTS hires a Redis client to interact with the Redis database.
- Redis Sentinel monitors the Redis database and shifts the control to replicated servers if the primary server failover.
- When an HSTS cluster is configured successfully we can test it by creating an Aspera HSTS node on any of the servers whether it is primary or the replicated server, that node API would be reflected in all the servers in a cluster, and the same thing occurs for deletion if we delete the node API, it would be deleted in the all of the servers.
- This is how the HSTS cluster environment is set up with highly available servers whenever a failover occurs or the primary HSTS server fails due to any reason, the Redis database would help, and with a minimum time of 5 minutes, the replicated server takes control and becomes the primary server.
Key Components of Aspera's High Availability Architecture
- Multiple Server Instances: Aspera achieves high availability by allowing the deployment of multiple server instances across geographically distributed locations. This redundancy minimizes the impact of server failures, ensuring that users can seamlessly access the transfer service.
- Load Balancing: Load balancing is pivotal in distributing incoming data transfer requests across the available server instances. This not only optimizes resource utilization but also enhances fault tolerance, as traffic is redirected in the event of a server failure. Popular load-balancing solutions like Nginx or HAProxy can be integrated with Aspera.
- Automatic Failover Mechanism: Asensuring Apera's high availability architecture incorporates an automatic failover mechanism, that if one server instance becomes unavailable, the system seamlessly switches to an operational instance. This minimizes disruption and keeps data transfer workflows running smoothly.
Considerations for implementing Aspera's High Availability
Geographic Distribution
Strategically deploy server instances across geographically distributed locations to ensure optimal performance and minimize.
- Latency: This geographic diversity enhances the overall high availability of the system.
- Monitoring and Maintenance: Implement robust monitoring tools to keep track of server health, network conditions, and overall system performance. Regular maintenance, including updates and security patches, is crucial to sustaining high availability.
- Disaster Recovery Planning: While high availability mitigates many risks, having a comprehensive disaster recovery plan in place is essential. This includes regular backups, documentation, and procedures for restoring operations in case of unforeseen events.
- Load Balancing: Integrate load balancing mechanisms to evenly distribute incoming network traffic across multiple server instances. This ensures that no single server becomes overwhelmed, optimizing resource utilization and preventing potential points of failure.
- Redundancy: Incorporate redundancy at various levels, such as server hardware, network connections, and data storage. Redundant components and failover mechanisms help maintain continuous operations even if one component experiences a failure.
- Scalability: Design the infrastructure to scale dynamically based on demand. Scalability allows the system to adapt to changing workloads by adding or removing resources as needed, ensuring consistent performance during both regular operations and peak usage periods.
- Network Connectivity: Ensure reliable and redundant network connectivity between geographically distributed server instances. A well-designed network infrastructure with redundant connections helps maintain communication and data transfer even if one network path experiences issues.
- Automated Failover: Implement automated failover mechanisms to detect and respond to server failures quickly. Automation reduces the response time, minimizing downtime and ensuring a seamless transition to backup resources in the event of a failure.
- Testing and Simulation: Regularly conduct testing and simulation exercises to validate the effectiveness of the high availability setup. This includes simulating various failure scenarios and observing how the system responds to ensure that the recovery mechanisms function as expected.
- Documentation and Training: Maintain comprehensive documentation of the high availability architecture and procedures. Provide training for the operations team to ensure they are familiar with the system's configuration, monitoring tools, and response procedures in the event of a failure.
- Compliance and Security: Adhere to industry compliance standards and implement robust security measures to protect the high availability infrastructure from potential threats. Regularly audit and update security protocols to address emerging vulnerabilities and maintain a secure environment.
- Vendor Support and Updates: Stay informed about updates, patches, and support provided by Aspera. Regularly apply updates and patches to ensure that the system benefits from the latest features, performance improvements, and security enhancements.

Aspera Console
Description: Aspera Console is a web-based interface as a central management interface for configuring, monitoring, and managing Aspera transfer servers and workflows.
High Availability Features: The console’s active/passive architecture requires a load balancer that monitors the health of each node and directs the traffic to the currently active system. One system is active and the second system is passive. The passive system becomes active if the active system goes down; when the faulty node recovers, it comes back online in a passive state but is available for failover if the active system fails.
