Move hot-cache workloads to Dragonfly Cloud
Dragonfly Cloud is a managed Redis- and Memcached-API-compatible service with self-serve "Flex" and custom-priced "Business" tiers. As of 2026-03-27, Dragonfly's pricing page shows Flex as pay-as-you-go with a pricing calculator example of "$8.00/GB/month" for AWS and notes that cloud-provider network charges are extra; it also advertises up to 20% annual-commit discounts and $100 trial credits. Dragonfly positions cost around provisioned memory rather than node-count planning, and its cloud page says customers can often reduce infrastructure costs versus Redis Enterprise and ElastiCache. For a cost-sensitive hot-cache where Redis-specific enterprise features are not the reason you stay, Dragonfly now has a clear hosted-cost story.
When to choose
Best for cost-sensitive plus low-ops cache workloads where Redis protocol compatibility is important but Redis Cloud's dedicated pricing floor or node-based scaling is hard to justify. The decisive factor is whether you can accept a migration project and validate behavior under Dragonfly's compatibility model in exchange for materially simpler cost math.
Tradeoffs
Pros: lower advertised hosted cost, managed service across AWS/GCP/Azure, Redis/Memcached API compatibility, simpler memory-based sizing. Cons: pricing examples are region-dependent, network charges are extra, and savings examples assume memory-efficiency gains that may not match every dataset.
Cautions
Do not treat the calculator's lower total as guaranteed savings: the pricing page explicitly assumes 20% data compression gains versus Redis and excludes cloud-provider network charges. Migration is not always instant even though Dragonfly markets itself as a drop-in replacement; its migration docs say you still need to choose between simpler snapshot/restore, replication for reduced downtime, or more complex sentinel-promotion paths for minimal downtime.
Stay on Redis Cloud and upgrade deliberately to Redis 8.x
Redis Cloud remains the most direct way to stay on official Redis while avoiding server-side OSS license compliance work. As of 2026-03-27, Redis pricing lists Free up to 30 MB, Essentials from "$0.007/hour" with a stated total of "$5/month," and Pro from "$0.014/hour" with a "$200/month" minimum for dedicated deployments. Redis's licensing page says Redis 8 and later are tri-licensed under RSALv2, SSPLv1, and AGPLv3, while Redis 7.4 through 7.8 remain RSALv2 or SSPLv1 and Redis 7.2 and earlier remain BSD-3-Clause. Redis Cloud docs list Redis 8.4, 8.2, 8.0, 7.4, and 7.2 release-note tracks, showing that Redis 8-era features are available in the hosted product.
When to choose
Best for enterprise or low-ops teams that want the official Redis roadmap, managed service support, and commercial licensing separation from AGPL concerns. The decisive factor is whether Redis Cloud's pricing floor and upgrade caveats are acceptable compared with the migration and validation cost of leaving.
Tradeoffs
Pros: official Redis distribution, commercial hosted product, established managed-service features, clear path to Redis 8.x. Cons: dedicated Pro starts at a much higher monthly minimum than Dragonfly's self-serve positioning, and Redis 8 upgrades can introduce behavioral changes.
Cautions
As of 2026-03-27, the Redis 8 licensing shift has already occurred: Redis 8 is tri-licensed and Redis 7.4 through 7.8 are still RSALv2/SSPLv1. For Redis Cloud users, the bigger migration blocker is not license compliance on the managed service but Redis 8 behavior changes: Redis's 8.0 release notes warn that ACL behavior changes because Search, JSON, time series, and probabilistic commands are folded into existing ACL categories, which can widen or narrow effective permissions if you use custom ACL rules.
