Amazon ElastiCache makes it easy to set up, manage, and scale distributed in-memory cache in the AWS Cloud. It provides a high performance, resizable, and cost-effective in-memory cache, while removing complexity associated with deploying and managing a distributed cache environment. With Amazon ElastiCache Serverless, you can create a highly available cache in under a minute without infrastructure provisioning or configuration, and never have to worry about capacity. Amazon ElastiCache is Redis OSS- and Memcached-compatible.

Whitepapers and reports

Explore recent analyst reports and whitepapers for Amazon ElastiCache.


IDC found that interviewed organizations achieved significant value from using Amazon ElastiCache to manage the real-time performance of applications. Through reduced costs, greater staff efficiencies, and business enablement, IDC calculated that interviewed organizations achieved a total average annual benefit of $3.9 million per year, resulting in a three-year ROI of 449%.


Microservices-based applications have revolutionized the way applications are built by breaking down monolithic applications into smaller, independent services that communicate with each other. A best practice for microservices-based applications is to use in-memory caching to overcome data fragmentation and network latency challenges. This paper covers the advantages of microservices, the need for performance optimization, high availability, and how a cache-based messaging layer facilitates inter-microservice communication.


This e-book is a comprehensive guide to using Amazon ElastiCache with Redis OSS compatibility to build high performance applications. We provide a brief background on caching and when to use it. Then, we quickly dive deep core data modeling patterns, resource optimization, and advanced data types and patterns.

Watch Amazon ElastiCache experts speak on the latest innovations and enhancements with the most recent re:Invent breakout sessions, and learn how customers used Amazon ElastiCache within their application architecture.


Introducing Amazon ElastiCache Serverless                                       

With ElastiCache Serverless, you no longer have to provision, plan for, or manage your cache cluster capacity. ElastiCache Serverless helps you get started in under a minute with a distributed in-memory cache and instantly scales in and out to support even the most unpredictable application traffic patterns. In this session, learn how ElastiCache Serverless works and how it can help you accelerate application performance.


Caching improves performance and significantly reduce your cloud spend. Learn how you can save up to 55% in cost and gain up to 80x faster read performance using Amazon ElastiCache with Amazon RDS for MySQL (versus RDS for MySQL alone). Also, you will understand about the financial advantages of caching Amazon Aurora and Amazon RDS workloads, how to identify which of your databases would benefit the most from caching, and review practical examples of how to realize performance gains and cost savings.


Learn how HBO Max uses Amazon ElastiCache to cost-effectively scale and delight more than 76 million subscribers around the world. ElastiCache is a fully managed, in-memory data store that boosts application performance and reduces latency to microseconds. In this session, HBO Max shares how ElastiCache allows them to deliver ultra-fast, device-specific landing pages to their subscribers, manage seasonal spikes from highly anticipated worldwide releases, and realize significant cost savings. Learn how ElastiCache is designed to boost performance of your workloads and review its latest features.


Learn how ADP built a highly scalable and available cloud-native application suite and microservices platform, leveraging a broad array of AWS services, including Amazon ElastiCatche. Key benefits for ADP, which are passed on to its customers, include more efficient workflows, higher scalability and performance, more rapid innovation turn-around, and a more cost-effective infrastructure.


Learn how Carbon by Indigo supports farmers and helps them to get paid for the carbon credits they generate from regenerative agriculture. Jacob walks us through how they used Amazon ElastiCache and other AWS services to process petabytes of satellite imagery to determine the amount of carbon credits that were generated by farmers.


Heimdall Data: Query Caching Without Code Changes (2021)

Query caching improves database scale and application response times. However, it requires additional development with data integrity risk. In this episode, we explain how you can cache and invalidate with confidence into Amazon Elasticache as a SQL results cache using the Heimdall Proxy. Deployment requires no application changes.


Airbnb used Redis OSS extensively as an in-memory data store to reduce latency and provide sub-millisecond response for their website, search, images, payments, and more. They migrated from self-managed Redis OSS to fully-managed Amazon ElastiCache to reduce operational overhead and improve availability. They also realize multi-Availability Zone support, automatic failover, and maintenance.
