Redis in 2026: the licensing context
You can't talk about Redis hosting in 2026 without the licensing story. Redis changed its license away from open source (BSD) in 2024, which spawned forks — most notably Valkey (a Linux Foundation project, drop-in compatible) — and prompted many cloud providers to offer Valkey alongside or instead of Redis. Functionally they're compatible today, but it's worth knowing what you're actually running and under what license. Antirez (Redis's creator) returned and Redis re-added an open-source option (AGPL) in later releases, so the landscape is still settling.
For practical purposes: pick a managed offering, confirm whether it's Redis or Valkey, and know that your client code is almost certainly identical either way.
What you use Redis for (it changes the host choice)
| Use case | Durability need | Notes |
|---|---|---|
| Cache | Low (can rebuild) | Eviction policy matters most |
| Session store | Medium | Losing sessions logs users out |
| Queue / jobs (BullMQ, Sidekiq) | High | Persistence + reliability matter |
| Rate limiting / counters | Low-medium | Latency matters |
| Pub/Sub / realtime | Ephemeral | Connection limits matter |
A pure cache can tolerate a provider with no persistence. A job queue cannot. Match the offering to the job.
The providers
Redis Cloud (Redis Inc.)
The first-party managed service from the company behind Redis. Full feature set including Redis modules (search, JSON, time series), HA, and global options. If you want the canonical, fully-featured Redis with first-party support, this is it.
Amazon ElastiCache / MemoryDB
ElastiCache offers managed Redis/Valkey with strong AWS integration; MemoryDB is a Redis-compatible *durable* primary database with multi-AZ persistence — useful when you want Redis semantics but real durability. Great if you're on AWS.
Upstash
Serverless Redis with per-request pricing and an HTTP API — excellent for serverless/edge functions where persistent TCP connections are awkward. Scale-to-zero economics suit spiky, low-baseline workloads.
Google Memorystore
Managed Redis/Valkey on GCP with HA tiers, integrated into the Google Cloud ecosystem.
PandaStack
Disclosure: my platform. PandaStack runs managed Redis (via KubeBlocks on GKE) as a database you attach to your app, with scheduled and manual backups. The value is integration, not competing on Redis modules: add Redis to your PandaStack app and the connection string is injected automatically, so your cache/session/queue store is wired in without manual config.
REDIS_URL=redis://default:pass@host:6379This is especially handy for the common pattern of app + Postgres/MySQL + Redis all in one place — your Laravel/Rails/Node app gets its cache and queue backend next to its database.
Honest limits: PandaStack's Redis is aimed at being the cache/queue/session store next to your app, not a fully-featured Redis-modules platform (no managed RediSearch/JSON module suite like Redis Cloud). Free-tier instances are dev/hobby sized. For very large, modules-heavy, or globally-replicated Redis, Redis Cloud and the hyperscalers offer more specialized options.
The configuration choices that bite people
Eviction policy
If you use Redis as a cache, set a maxmemory and an eviction policy. The default in some setups is noeviction, which means once memory fills, writes fail instead of evicting old keys. For a cache you almost always want allkeys-lru or allkeys-lfu:
maxmemory 256mb
maxmemory-policy allkeys-lruPersistence
- RDB snapshots: periodic point-in-time dumps. Lower overhead, possible data loss between snapshots.
- AOF (append-only file): logs every write, more durable, more I/O.
- For a queue, you want AOF (or a durable offering like MemoryDB). For a pure cache, persistence may be unnecessary.
Connections
Reuse a single client/pool per process. Opening a connection per operation is the classic way to exhaust a Redis instance's connection limit under load.
