While perhaps not a HPC product, the popular in memory cache is often seen in HPC applications to serve inputs to the calculation nodes or store results and intermediate data from the highly parallel computation.

The change is effective immediately and will apply to all future releases. It may also additionally impact the naming of products that do not use the Redis codebase but are compatible such as Upstash.

The most significant impact of the change is to prevent third parties, such as cloud providers, from offering the product as a managed service without first becoming a Redis partner.

I believe Azure Cache for Redis will continue to be available (with additional features, being a licensed product) though other services, such as those offered by Digital Ocean, are likely to be affected.
