4 Best IBM Aspera Alternatives for Large File Transfers

IBM Aspera Alternative: Fast File Transfer of Large Files

IBM Aspera is a well-known data transfer solution. It’s used by many companies as an FTP replacement and does well transferring large files at high speed around the globe. It’s based on the point-to-point User Datagram Protocol (UDP) that overcomes Transmission Control Protocol/Internet Protocol (TCP/IP) insufficiency over long-distance Wide Area Networks (WAN). 

Although it achieves maximum speed in point-to-point data transfers, IBM Aspera is not the best solution for other use cases, such as multi-directional transfer and sync. 

Specifically, Aspera is a poor choice if you need to:

  • Synchronize or distribute files to several locations in real-time (e.g., remote offices and cloud regions).

  • Synchronize files bidirectionally between 2 or more systems. 

  • Keep several geographically distributed servers in sync.

  • Collaborate on the same file among multiple contributors or editors, within or across multiple locations. In general, Aspera isn’t useful in remote work use cases where large, high-value digital assets need to be synchronized behind the scenes by contributors in a person-to-person fashion.

By contrast, Resilio Connect uses a P2P (peer-to-peer) architecture to achieve the fastest transfer, sync, and replication speeds in the industry. We’ve achieved transfer throughput speeds of 100+ Gbps and have transferred 500 GB of data in GCP from London to Australia in 50 seconds.

Resilio Connect can sync file changes in any direction across your entire environment quickly, reliably, and efficiently, regardless of file size or physical distance. For example, contributors working on a large digital asset can make changes and rapidly sync them with as many other contributors as they choose. 

This, alongside Resilio’s proprietary WAN optimization technology, makes our solution a superior alternative to IBM Aspera in many scenarios.

In this post, we’ll review how Resilio Connect compares to IBM Aspera in several use cases. We’ll also summarize 3 additional IBM Aspera alternatives for large file transfers.

Use Cases for Aspera vs. Resilio Connect

File Transfer to Several Teams (Resilio Connect Wins)

Resilio Connect outperforms Aspera when you need to transfer files to or between end users on several teams. In fact, Resilio excels at synchronizing files of any size and type, and many millions of files in real-time and across any network. 

Our solution combines a P2P architecture and proprietary WAN optimization technology to maximize your environment’s bandwidth and fully utilize any network. 

It also splits files into blocks that are sent concurrently and independently to several destinations. Combining the networks between machines into a single meshed network significantly increases the transfer speed, which leads to faster delivery of the files.

In addition, Resilio’s unique P2P architecture overcomes the downsides of traditional point-to-point (aka client-server) architectures used by solutions like Aspera. These traditional architectures come in one of two options:

  • Hub and spoke, in which data must always pass through a central hub to reach its destination. This hampers transfer speeds, as clients must always send their data to the hub, which in turn transfers it to other devices. This also presents a single point of failure — i.e., if the hub server goes down, file synchronization across the entire environment fails.

  • Follow the sun, in which data must pass between devices in a rigid sequence, e.g., from Server 1 to Server 2 to Server 3, and so on. This model suffers from many of the downsides of the hub-and-spoke model.

Due to these drawbacks, point-to-point transfers are not suitable for scenarios where files need to be concurrently transferred or synchronized to multiple systems in parallel. 

With Resilio Connect’s P2P architecture, all devices in your environment can take part in the transfer or sync process. Combined with file chunking, this enables you to take advantage of your environment’s full bandwidth, resulting in transfer speeds that are 3–10x faster than traditional point-to-point solutions.

This also means you can scale distribution and sync in any direction. Resilio’s P2P architecture sends a single file to as many other places as needed. As a result, it takes the same time to distribute or sync files across hundreds of servers as it does to just 2 servers.

Additionally, the P2P architecture doesn’t have a single point of failure. If one or more servers, storage devices, or network connections go down, this won’t break the replication process. Instead, Resilio can dynamically route around the outage and find the optimal path to deliver files to their destination.

Synchronize Files Across Locations (Resilio Connect Wins)

Aspera and its FASP protocol are focused on fast file transfer between two endpoints. But when you need to keep several geographically distributed servers in sync, Resilio Connect is the winner and provides an excellent Aspera alternative. 

Resilio Connect can easily monitor tens of millions of files for changes and deliver changed files extremely fast to multiple locations. As with transferring files to several teams, Resilio’s P2P and file chunking functionality increases flexibility and transfer speed while also ensuring reliability by eliminating single points of failure.

Resilio Connect also employs WAN optimization in the form of our proprietary Zero Gravity Transport™ (ZGT). Designed for spotty, slow, and unreliable connections, ZGT is ideal for several use cases, including fast file sync across geographically distributed locations, remote data collection and ingestion in extreme environments, and more.

ZGT measures packet loss, latency, and throughput over time. This enables it to adjust and maintain consistent speeds and adapt to changing conditions in real-time. 

ZGT works by:

  • Constantly probing the RTT (Round Trip Time) using a congestion control algorithm to identify and maintain the ideal data packet send rate.

  • Retransmitting lost packets in groups once per RTT to decrease unnecessary retransmissions.

  • Using interval acknowledgments for groups of packets to enhance transfer speed, with each acknowledgment containing information about lost packets.

Distribute Files to Several Locations (Resilio Connect Wins)

Aspera is a strong point-to-point large data transfer solution. Conversely, Resilio Connect’s P2P multidimensional data transfer provides concurrent and independent data transfer to several destinations. It works very well with cloud, on-premise geographically distributed servers, or any combination of the above. Multidimensional block-level data transfer outperforms synchronous point-to-point file transfer in all multi-destination transfer scenarios.

File Transfer To or From Cloud/Private Object Storage (Resilio Connect Wins)

There are many data transfer needs when you work with the cloud. IBM Aspera and Resilio Connect have similar results with the simple use case of uploading or downloading data quickly from cloud object storage.

However, Resilio Connect outperforms Aspera as a file transfer solution in more complex use cases, such as:

  • Creating a master copy of the project and distributing it between teams.

  • Sharing assets from the cloud with geographically distributed teams.

  • Uploading data to the cloud and delivering to another location.

  • Connecting any local server or NAS to the cloud.

File Transfer of a Few Large Files from Team A to Team B (Tie)

Aspera and Resilio Connect are both capable solutions when you need to send a few files between two locations over the WAN. Both are compatible with popular operating systems like Windows and Linux, and both are faster and more reliable than File Transfer Protocol (FTP) for large data sets and big data. The key difference is how they accomplish their transfers.

Rather than accelerate data, Aspera removes traffic bottlenecks by optimizing bandwidth efficiency at all stages of the transfer. In addition, it respects other traffic, preventing congestion and ensuring all transfers proceed in a timely fashion.

Resilio Connect, meanwhile, employs ZGT, which overcomes packet loss and latency regardless of distance. In addition, Resilio Connect does have an advantage when working over the local area network (LAN) since it can fall back to TCP/IP, which delivers high performance while being less aggressive to local traffic.

Transfer a Few Files to External Partners (Aspera Wins)

When you need to send a number of files or do file sharing with external partners, have a nice UI, the ability to leverage WAN-optimized speed inside a browser, and have available bandwidth, Aspera is the better choice.

Other Key Benefits of Resilio Connect
