Compare Dragonfly vs. Terracotta

Dragonfly serves as a seamless substitute for Redis, offering enhanced performance while reducing costs. It is specifically engineered to harness the capabilities of contemporary cloud infrastructure, catering to the data requirements of today’s applications, thereby liberating developers from the constraints posed by conventional in-memory data solutions. Legacy software cannot fully exploit the advantages of modern cloud technology. With its optimization for cloud environments, Dragonfly achieves an impressive 25 times more throughput and reduces snapshotting latency by 12 times compared to older in-memory data solutions like Redis, making it easier to provide the immediate responses that users demand. The traditional single-threaded architecture of Redis leads to high expenses when scaling workloads. In contrast, Dragonfly is significantly more efficient in both computation and memory usage, potentially reducing infrastructure expenses by up to 80%. Initially, Dragonfly scales vertically, only transitioning to clustering when absolutely necessary at a very high scale, which simplifies the operational framework and enhances system reliability. Consequently, developers can focus more on innovation rather than infrastructure management.

Terracotta Server Platform is an open source server platform that provides distributed in-memory data management for applications using Terracotta technologies such as Ehcache and TCStore. It enables clustered caching by allowing applications to connect to a Terracotta Server and store cache data across server-side resources. The platform can be deployed as a simple two-node tandem or expanded into a larger Terracotta Server Array for added scalability, performance, and failover protection. Terracotta Server helps teams manage large volumes of data in memory, making it useful for workloads that need fast access to shared cached data. Its key capabilities include high availability, configurable health monitoring, automatic node reconnection, and simplified capacity planning. The platform supports JDK 17 or higher and can be started from a local kit or Docker image. Developers can connect clustered Ehcache clients using Java or XML configuration and define server-side off-heap resources for cache storage. Commercially supported versions from IBM offer additional capabilities such as fast-restart persistence, advanced management, and security features. Terracotta Server Platform is a practical option for teams that want to extend Ehcache with distributed caching and improve application performance across clustered environments.
