Bloomberg wins the 2023 Superuser Awards.


Bloomberg has won this year’s Superuser Awards, which recognizes organizations that have used open infrastructure to improve their business while contributing back to the OpenInfra community. The news was announced today by the OpenInfra Foundation.

As an open source first company, Bloomberg has made great strides in adopting and contributing back to open source software over the past two decades. Open infrastructure has been a key driver throughout this process, playing a pivotal role in enabling their business to rapidly stand up on-premise cloud infrastructure across the globe to accommodate their growth. Open source cloud technology also enables them to improve the power efficiency of the data centers and helps reduce their carbon footprint.

Bloomberg is heavily involved in the OpenInfra community and user base. They have also played a role in advancing multiple open source technologies and are very active in the Python community.

In 2023, Bloomberg launched a Free and Open Source Software (FOSS) Contributor Fund (, an open source funding initiative of which Apache Arrow, Curl and Celery were chosen by Bloomberg employees and open source contributors as the inaugural recipients of the grants.

Another achievement is their global compute and storage investment consisting of over 400K OpenStack cores, several petabytes of RAM and hundreds of petabytes of replicated Ceph block and object storage. In addition, they also run hundreds of bare-metal and virtual Kubernetes clusters. More recently, they have also enacted plans to expand their open infrastructure footprint into the networking arena with SONiC, in the hope to leverage to manage the multi-terabit class network fabric.

Bloomberg overcame many interesting operational hurdles in the past year, e.g., as part of a newly renovated object storage platform, they have IDed and helped resolve a multi-site RGW synchronization bug in Ceph (BUG #57562) that arose at high levels of concurrency. While upgrading the OS and firmware across their fleet of thousands of infrastructure servers with zero downtime, they IDed and worked with the community to resolve a tricky live-migration issue upstream (BUG 1982284) that prevented their rolling hypervisor deployments from being transparent to the customers.

They have expanded their private cloud infrastructure and BGP-based IP networking fabric globally. These technologies are now in use by more than 8,000 developers on multiple continents. They also started evaluating different tiers of file and block storage to fill high-performance infrastructure needs. With the use of OpenStack’s vendor-neutral design, they can rapidly incorporate these emerging technologies into their infrastructure with ease.
