A high-performance, distributed memory object caching system, generic in nature called Memcached is intended for use in speeding up dynamic web applications by alleviating database load.

Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering. The simplicity of its design promotes quick deployment, ease of development, and solves many problems facing large data caches. Its API is available for most popular languages.

Niles Partners is launching a product which will configure and publish Memcache, to produce free implementations of distributed or otherwise scalable and high availability which is embedded pre-configured tool and ready-to-launch Machine image on Azure that contains MariaDB.

Memcached basically runs on Unix-like operating systems and on Microsoft Windows. It depends on the libevent library.

A large hash table is provided by its APIs. Applications using Memcached typically layer requests and additions into RAM before falling back on a slower backing store, such as a database.

This is the general knowledge that one must have before started working on Memcache.

Let us now know what exactly its software architecture is and what its functionalities are.

Software architecture

The system uses a client-server architecture. The servers maintain a key–value associative-array; the clients populate this array and query it by key. The length of the Keys are up to 250 bytes and values can be at most 1 megabyte in size.

If we talk about the typical deployment of this architecture then it can have several servers and many clients. However, it is possible to use Memcached on a single computer, acting simultaneously as client and server. The size of its hash table is often very large. It is limited to available memory across all the servers in the cluster of servers in a data center. Where high-volume, wide-audience Web publishing requires it, this may stretch too many gigabytes.

Now talking about MariaDB, we can say that it is one of the most popular database server which is being widely used.

MariaDB turns data into structured information in a wide array of applications, ranging from banking to websites. It is an enhanced, drop-in replacement for MySQL. It is used because it is fast, scalable and robust, with a rich ecosystem of storage engines, plugins and many other tools make it very versatile for a wide variety of use cases.

MariaDB intends to maintain high compatibility with MySQL, ensuring a drop-in replacement capability with library binary equivalency and exact matching with MySQL APIs and commands.

Not only this but MariaDB provides much more than MySQL be it related to security, support etc. MariaDB development is more open and vibrant.

MariaDB combined with Memcached and Lamp provides a better and fast cached server with high level of flexibility and ease of use.
