# Memcached: in-memory cache deployment

Deploy Memcached in a cloud container where available. It can reduce repeated database work when configured for your application; response time depends on the workload and resources.

## Memcached features on Deplomo Cloud

Memcached supports multithreaded operation. Network access and available resources depend on the deployment configuration.

### Multithreaded architecture

Memcached supports multithreaded operation. Throughput depends on available CPU resources, network, and workload.

### In-memory caching

Memcached stores cache entries in memory using a key-value model. Response time depends on the application and deployment.

### Reducing the load of database queries

Caching can reduce repeated database queries when the application is configured to use Memcached.

### Private-network access

Connect backend services over a private network where configured. Verify network access and avoid exposing cache services publicly.

### Client libraries and application integrations

Memcached has client libraries for several languages. WordPress plugin and framework compatibility depends on your application setup.

### Resource sizing and package limits

Set Memcached memory according to your cache needs and the RAM available in your zone package.

## Frequently asked questions about Memcached

Answers to common developer questions about Memcached, application connections, and deployment:

What is Memcached, and how can it help with website caching?

How does Memcached differ from Redis?

How do you deploy Memcached on Deplomo Cloud?

How is Memcached used with WordPress and online stores?

How is Memcached network access configured on Deplomo Cloud?

## Memcached: an in-memory cache for web applications

Memcached is an open-source, in-memory key-value cache for objects and query results. Applications can use it to cache selected data and reduce repeated database work; the benefit depends on cache design and hit rate.

### Memcached compared with file-based caching

Memcached stores cache entries in memory and supports multithreaded operation. Performance depends on resources, cache behavior, network, and workload.

### The application of memcached in database optimization and web services

Applications often use caching alongside a [Cloud database](/products/databases)  database to reduce repeated queries. The effect depends on the data cached and application behavior.

### Memcached setup and network configuration

Self-managed Memcached setup involves configuring memory limits and network access. Container deployment can simplify setup, but review the service version, resource limits, and network settings. International service creation is currently paused.

### Using Memcached with WordPress and WooCommerce

For example, when using a cache with [cloud WordPress hosting](/marketplace/apps/wordpress)  , a compatible object-cache plugin can use Memcached for selected entries. The impact on queries and page performance depends on plugin settings and the application.

### Memcached or Redis: choosing a cache for your project

Developers comparing cache options may consider [. Redis supports additional data structures and persistence options, while Memcached provides an in-memory key-value cache. Choose based on the data and features your application needs.](/marketplace/apps/redis) They hesitate. If your project requires complex data structures, processing queues (queues), message publishing and sharing systems, or persistent storage of session data on disk memory, Redis provides a more comprehensive platform. But if your goal is exclusively to quickly cache strings and web results with the least possible complexity and without the need to permanently maintain information, the memcached server is a much lighter, less expensive and more straightforward option.

### Memcached package and deployment options

The existing Free plan includes 256 MB of RAM. No promotional credits are included, and international service creation is currently paused.

## Plan a Memcached deployment

Run Memcached in an isolated container within a fixed monthly package, without managing Linux yourself.
