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:
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.
| Comparison | Memcached on Deplomo Cloud | Self-managed server setup | File-based cache |
|---|---|---|---|
| Setup and deployment | Container deployment; availability depends on service status | Setup steps depend on the server and deployment | Integration effort depends on the application |
| Read and write latency | Latency depends on the cache, network, and application | Latency depends on the operating system and workload | Disk access time depends on the storage and workload |
| Networking and access | Private-network access where configured | Firewall requirements depend on the deployment | File access controls depend on the server configuration |
| Resource management and scalability | RAM allocation within package limits | Resource changes depend on the package and service | Storage use depends on the selected caching approach |
| Behavior under load depends on workload and resources | Monitor service health and configure resources for your workload | Memory limits and application behavior affect service availability | File locking depends on the caching implementation |
The application of memcached in database optimization and web services
Applications often use caching alongside a Cloud database 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 , 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. 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.
