Memcached is a valuable tool for improving the performance and scalability of applications by reducing the need to repeatedly access slower data sources such as databases. It is particularly beneficial for applications with a high read-to-write ratio and can be a key component in building highly responsive and efficient web services.

Frequently Asked Questions
Here are the basic system requirements for deploying Memcached:
Recommended hardware requirements:
CPU: 2-4 cores
RAM: 4-8GB
Storage: 20GB+ (recommended for larger setups)
Operating system:
Officially supported: Linux (various distributions), FreeBSD, NetBSD, OpenBSD, macOS, Windows.
Check the Memcached documentation for specific information.
Memcached is a high-performance, distributed memory caching system that is widely used to accelerate the performance of web applications by caching data in memory. Here are some common use cases for Memcached:
Session caching, database query result caching, full-page caching, object caching, API response caching, dynamic content acceleration, content delivery network (CDN) support, load balancer session persistence, leaderboards and counting, real-time analytics, and application-level locking.
Here are some notable alternatives to Memcached:
Redis, EHCache, Memcachedb, Couchbase, Hazelcast, Aerospike:, Apache Kafka, RocksDB, GridGain, and Tarantool.
Here are some key differentiators between Memcached and other caching solutions:
Type of storage:
Memcached: In-memory caching – stores data solely in RAM for lightning-fast access but loses data upon server restart.
Other caching: Can be in-memory (Redis), on-disk (Varnish), or database-integrated (Ehcache). Each offers different trade-offs between speed, persistence, and complexity.
Data structure:
Memcached: Simple key-value store – ideal for unstructured data like strings, objects, and arrays.
Other caching: May offer more complex data structures like lists, sets, or hashes (Redis, Couchbase) or specific object formats (Ehcache).
Persistence:
Memcached: Non-persistent by default – data vanishes when the server restarts. Persistence options exist but are less efficient.
Other caching: Can be persistent (Redis, Aerospike, Couchbase) or offer hybrid approaches (Varnish).
Scalability:
Memcached: Horizontally scales well by adding more servers to distribute the load, ideal for high-traffic applications.
Other caching: Scalability options vary depending on the specific solution.
Complexity:
Memcached: Simple setup and configuration, minimal resource requirements, making it easy to deploy and manage.
Other caching: Complexity can vary significantly. Some offer easy setup (Ehcache), while others require more configuration and expertise (Redis, Couchbase).
