In this post, we talk about the benefits of caching in generative AI applications. We also elaborated on a few implementation strategies that can help you create and maintain an effective cache for your application.

MaiCoin is a leading cryptocurrency exchange and brokerage platform in Taiwan. The MaiCoin platform previously ran on a set of Amazon ElastiCache deployment clusters on Redis OSS. This post explores MaiCoin’s practical approaches using RedisShake for migrating from Amazon ElastiCache for Redis OSS to Amazon ElastiCache for Valkey using blue/green deployment strategies.

As a global leader in the online travel industry, Booking.com continuously works to improve the travel experience for its users. Latency is a key factor in achieving this—nobody likes waiting for their search results to be returned. In this post, we share how Booking.com designed a well-architected Amazon ElastiCache-based feature platform, achieving ultra-low latency and high throughput, to ensure the best possible user experience.

re:Invent is a great opportunity for customers and builders who use AWS to share what they have built and why, architectural patterns, and best practices in the form of breakout sessions and workshops. In case you missed some of these sessions, or you wanted to get caught up on why customers like Expedia, Scopely, Adobe, and Amazon.com are building on ElastiCache, you can read this helpful summary of some of the ElastiCache highlights from re:Invent 2025.

This post shows how to build a semantic cache using vector search on Amazon ElastiCache for Valkey. As detailed in the Impact section of this post, our experiments with semantic caching reduced LLM inference cost by up to 86 percent and improved average end-to-end latency for queries by up to 88 percent.

Today, we’re announcing a new integration between Mem0 Open Source, Amazon ElastiCache for Valkey, and Amazon Neptune Analytics to provide persistent memory capabilities to agentic AI applications. This integration solves a critical challenge when building agentic AI applications: without persistent memory, agents forget everything between conversations, making it impossible to deliver personalized experiences or complete multi-step tasks effectively. In this post, we show how you can use this new Mem0 integration.

Amazon Ads enables businesses to meaningfully engage with customers throughout their shopping journey, reaching over 300 million audience in the US alone. Delivering the right ad to the right customer in real time at a global scale requires highly available, low-latency infrastructure capable of processing tens of millions of requests per second. In this post, […]

Alight Solutions is a leading cloud-based human capital technology and services provider that has focused its operations on integrated benefits administration, healthcare navigation, and employee experience solutions. In this post, we share how Alight Solutions transformed their caching infrastructure using ElastiCache while maintaining strict performance requirements, achieving over 60% cost reduction, 70-80% reduction in operational overhead, migration of gigabytes of data with sub-0.5 millisecond performance for millions of users, and a 99.99% reduction in incident rate.

In this post we show you how to build a secure Amazon ElastiCache for Valkey cluster using Terraform, implementing best practices and comprehensive security controls including encryption, authentication, and network isolation.

GroundTruth, an advertising platform leading the way in location- and behavior-based marketing, empowers brands to connect with consumers through real-world behavioral data to drive real business results. As our advertising platform scaled to process increased volume of ad requests and third-party segment ingestion, maintaining our Aerospike-based caching infrastructure introduced significant operational complexity and rising costs, while also compromising performance and limiting our ability to scale efficiently. To meet our requirements we implemented Amazon ElastiCache for Valkey, which streamlined our operations, improved reliability, and reduced costs. In this post, we walk through our migration journey, covering the migration strategy we adopted, the optimizations we made to reduce cost by 45%, reliability improvements including reducing write failures by 20x, and operational gains from managed service capabilities.
