Solarflare Launches Revolutionary Cloud Onload Application Acceleration Platform

More than 25 percent of today’s cloud data center servers are wasted; platform unleashes these servers for revenue generation

IRVINE, Calif., May 7, 2019 – Solarflare, the leader in application-optimized network solutions, today announced the Cloud Onload® application acceleration platform designed to allow data centers to reclaim 25 percent or more in server resources, by improving server efficiency and performance. The first in a planned family of application acceleration products, Cloud Onload is the cornerstone of the company’s plan to remove billions of dollars of waste from today’s private and public cloud infrastructure investments. Customers can convert wasted servers into valuable services for their customers, leading to increased revenue and lower costs.

“Today’s consumers expect advanced e-commerce shopping experiences, enhanced video streaming, and generally higher service levels at falling, or at most, equal prices,” said Russell Stern, president and CEO at Solarflare. “Our groundbreaking Cloud Onload application acceleration platform is a major step forward for data centers that want to provide superior end-user experiences, while saving millions of dollars in new infrastructure investments.”

According to International Data Corporation, cloud IT infrastructure revenues surpassed traditional IT infrastructure revenues for the first time in the third quarter of 2018, and totaled $66.1 billion for the year. Cloud Onload disrupts this trend by significantly reducing how much operators must spend to build out their cloud data centers. A large cloud data center operator undertaking a million-server buildout can achieve equivalent capacity with 25 percent fewer servers using Cloud Onload, resulting in a savings of over $1 billion. The software improves the scalability of all network applications for cloud networks based on Linux, which The Linux Foundation says runs 90 percent of the public cloud workload and IDC has identified as the only endpoint operating system growing at a global level.

“Solarflare’s patented kernel bypass technology, which has become the de facto standard for the world’s electronic trading platforms, enables Cloud Onload to improve application acceleration by as much as 10X while significantly reducing CPU utilization,” said Steve Pope, co-founder and CTO at Solarflare. “The demand for this approach grows with the adoption of faster networks and modern web applications.”

How Cloud Onload Accelerates

Cloud Onload dramatically accelerates and scales a data center’s network-intensive in-memory databases, software load balancers and web servers so a single server can do the work of four with improved reliability, enhanced quality of service (QoS) and higher return on investment. 

The platform reduces latency while increasing transaction rates for nearly all network-intensive Transmission Control Protocol (TCP) applications on physical servers as well as in virtualized environments. Benchmark testing has demonstrated the following performance improvements:

  • In-memory databases including Couchbase, Memcached and Redis: 2X
  • Software load balancers including NGINX and HAProxy: 2-10X
  • Web servers/applications including NGINX and Node.js: 50 percent

Data centers can use the platform to achieve Remote Direct Memory Access (RDMA)-like performance without any modifications to existing software applications. Tailored to run in any Linux environment, whether open source, bare metal, virtual machine or container, Cloud Onload is fully POSIX compliant to ensure compatibility with TCP-based applications, management tools and network infrastructures.


Available now, Solarflare’s Cloud Onload application acceleration platform runs on 10/25/40/50/100GbE networks. For more information about Cloud Onload, visit

RedFit IDC SKEDD Connector

Sponsored by Wurth Electronics and Mouser Electronics

Why attach a header connector to your PCB when you really don’t need one? If you’re plugging a ribbon cable into your board, particularly for a limited-use function such as provisioning, diagnostics, or testing, it can be costly and clunky to add a header connector to your BOM, and introduce yet another component to pick and place. Wouldn’t it be great if you could plug directly into your board with no connector required on the PCB side? In this episode of Chalk Talk, Amelia Dalton chats with Ben Arden from Wurth Electronics about Redfit, a slick new connector solution that plugs directly into standard via holes on your PCB.
