0/10
Write-Back Cache
Improves write performance by writing data to cache first and then to storage. Benefits include faster write operations and reduced load on storage.
Content Delivery Network (CDN)
Optimizes delivery of web content and services. Benefits include reduced latency, high availability, and scalability.
Read-Through Cache
Guarantees that only the most recent data is provided to the client. Benefits include data consistency and ease of implementation.
Cache-Aside
Improves performance by loading data into the cache only when necessary. Benefits include precise control over cache entries and reduced unnecessary caching.
Time To Live (TTL)
Defines the lifespan of data in the cache which helps in managing the staleness of cached data. Benefits include automatic cache invalidation and simplified cache updates.
Geographical Load Distribution
Distributes client requests based on geographical location. Benefits include reduced latency, localized content, and balanced load among servers.
Write-Through Cache
Ensures data consistency between cache and storage system. Benefits include immediate updates and simple design.
Write-Around Cache
Reduces the cache being flooded with write operations. Benefits include less cache memory usage and reducing the risk of cache pollution.
Cache Invalidation
Ensures that outdated or incorrect data is removed or updated in the cache. Benefits include consistency, accuracy, and control over the cached data.
Distributed Hash Table (DHT)
Provides a decentralized method to store and retrieve data. Benefits include scalability, fault tolerance, and distributed nature.
