Question: What is the difference in pricing between ElastiCache and API Gateway Cache?

Answer

Amazon Web Services (AWS) offers various caching solutions to improve the performance of your applications. Two prominent services include Amazon ElastiCache and Amazon API Gateway caching.

ElastiCache Pricing

Amazon ElastiCache pricing depends on the instance type and the region where your instances are running. Charges accrue by the hour, per each hour or partial hour your ElastiCache node runs. There are no upfront costs, and you pay only for what you use.

You can find more details on the official ElastiCache Pricing Page.

# Example of how you might create and configure an ElastiCache cluster using Boto3 import boto3 client = boto3.client('elasticache') response = client.create_cache_cluster( CacheClusterId='my-memcached-cluster', Engine='memcached', CacheNodeType='cache.r5.large', # Pricing varies by node type NumCacheNodes=10, # other configuration options... )

API Gateway Cache Pricing

API Gateway caching comes at an additional hourly cost and varies depending on the cache size you select. Caching in API Gateway reduces the number of calls made to your backend and improves latency.

You can find more details on the official API Gateway Pricing Page.

# Example of how you might enable caching on a stage in API Gateway using Boto3 import boto3 client = boto3.client('apigateway') response = client.update_stage( restApiId='my-api-id', stageName='prod', patchOperations=[ { 'op': 'replace', 'path': '/cacheClusterEnabled', 'value': 'true' }, { 'op': 'replace', 'path': '/cacheClusterSize', 'value': '0.5' # Pricing varies by cache size }, # other configuration updates... ] )

While both services offer caching capabilities, their use-cases and pricing models are different. You would choose between them based on the requirements of your specific application.
