Companies favor distributed caching solutions in modern web applications because they deliver the advantages of scalability and consistency, and high availability. The drawback of local caching becomes apparent when applications exist across different servers or containers because it restricts data storage to individual application instances. Such situations result in data inconsistency because each application instance preserves an independent version of the data within its local cache. Distributed caching eliminates problematic data inconsistencies because it deposits data on shared servers which all application instances can access for consistent and current cache content.
Distributed caching provides scalability as its main advantage. Applications using distributed caches can grow horizontally through new node additions which enables them to process bigger datasets and increased requests. This approach works best for cloud-native programs serving a large user base who need maximal efficiency. A distributed cache incorporates fault tolerance features because it duplicates cached information throughout its nodes so data remains safe when one node fails. Managed infrastructure via central control systems allows to track and update and maintain their cache facilities efficiently. The application performance and reliability benefits from distributed caching by delivering a scalable and robust solution.
