Cache

A Cache represents a managed in-memory data store for caching, session storage, and real-time workloads. It supports Redis and Memcached engines. On AWS this is ElastiCache, on GCP Memorystore, and on DigitalOcean a Redis database (Memcached is not supported on DO).

Config

Property	Type	Required	Description
name	string	yes	Unique resource name
id	string	no	Explicit ID (auto-generated UUID if omitted)
provider	string	no	Provider label for multi-provider configs
tags	Record<string, string>	no	Arbitrary key-value metadata
engine	'redis' | 'memcached'	yes	Cache engine
instanceType	string	yes	Instance type (provider-specific, e.g. cache.t3.micro)
network	Vpc | string	no	Vpc for network placement
memorySize	number	no	Memory size in GB (GCP Memorystore)
nodeCount	number	no	Number of nodes (clustered Redis)
version	string	no	Engine version (e.g. '7.0')
authEnabled	boolean	no	Enable authentication token
maintenanceWindow	string	no	Preferred maintenance window (e.g. 'sun:03:00-sun:04:00')
snapshotRetention	number	no	Snapshot retention in days (Redis)

Example

import { Vpc, Cache } from '@kykucloud/types'

const myVpc = new Vpc({ name: 'my-vpc', cidr: '10.0.0.0/16', region: 'eu-central' })

const redis = new Cache({
  name: 'session-cache',
  engine: 'redis',
  instanceType: 'cache.t3.micro',
  network: myVpc,
  version: '7.0',
  nodeCount: 2,
  authEnabled: true,
  snapshotRetention: 7,
})

Provider Support

Provider	Supported	Backend
AWS	✅	ElastiCache (Redis / Memcached)
GCP	✅	Memorystore (Redis / Memcached)
Hetzner	❌	Not available
DigitalOcean	✅	Managed Redis (Memcached not available)

Notes

• AWS ElastiCache instance types use cache.* prefix (e.g. cache.t3.micro, cache.r6g.large). Supports both Redis (with clustering) and Memcached. Multi-AZ with automatic failover for Redis.
• GCP Memorystore uses instance types like basic, standard, highmem tiers. Tier maps to memory size (GB). For Redis, the memorySize configures the instance capacity.
• DigitalOcean offers managed Redis only (no Memcached). Sizing via plan slugs.
• Network isolation: On AWS and GCP, the cache can be placed in a VPC for private network access. DO Redis is accessible via public endpoint by default.
