memcached features and specs

  • High Performance
    Memcached is incredibly fast and efficient at caching data in memory, enabling quick data retrieval and reducing the load on databases. Its in-memory nature significantly reduces latency.
  • Scalability
    Memcached can be easily scaled horizontally by adding more nodes to the caching cluster. This allows it to handle increased loads and large datasets without performance degradation.
  • Simplicity
    Memcached has a simple design and API, making it easy to implement and use. Developers can quickly integrate it into their applications without a steep learning curve.
  • Open Source
    Memcached is free and open-source software, which means it can be used and modified without any licensing fees. This makes it a cost-effective solution for caching.
  • Language Agnostic
    Memcached supports multiple programming languages through various client libraries, making it versatile and suitable for use in diverse tech stacks.

Possible disadvantages of memcached

  • Data Volatility
    Memcached stores data in RAM, so all cached data is lost if the server is restarted or crashes. This makes it unsuitable for storing critical or persistent data.
  • Limited Data Types
    Memcached primarily supports simple key-value pairs. It lacks the rich data types and more complex structures supported by some other caching solutions like Redis.
  • No Persistence
    Memcached does not offer any data persistence features. It cannot save data to disk, so all information is ephemeral and will be lost on system reset.
  • Size Limitation
    Memcached has a memory limit for each instance, thus, large-scale applications may need to manage multiple instances and ensure data is properly distributed.
  • Security
    Memcached does not provide built-in security features such as authentication or encryption. This can be a concern in environments where data privacy and security are critical.

Docker Hub features and specs

  • Wide Availability
    Docker Hub is a widely used repository for Docker images, making it easy to find and share container images.
  • Ease of Use
    The interface of Docker Hub is user-friendly and straightforward, allowing for easy navigation and management of images.
  • Integrated with Docker CLI
    Docker Hub seamlessly integrates with Docker's command-line interface, facilitating smooth operations for pulling, tagging, and pushing images.
  • Automated Builds
    Docker Hub supports automated builds from source code repositories, ensuring that Docker images are always up-to-date with the latest code changes.
  • Third-Party Repository Support
    Docker Hub supports linking and synchronizing with third-party source code repositories, enabling continuous integration and deployment workflows.
  • Free Tier
    Docker Hub offers a free tier which allows users to access core functionalities and host a limited number of private repositories without cost.

Possible disadvantages of Docker Hub

  • Rate Limits
    Docker Hub enforces rate limits on image pulls for anonymous and free-tier users, which can hinder CI/CD pipelines and other automated systems.
  • Security Concerns
    Publicly available images on Docker Hub might be susceptible to vulnerabilities and malicious software, posing potential security risks if not properly vetted.
  • Limited Private Repositories
    The free tier of Docker Hub allows for only a limited number of private repositories, which might not be sufficient for larger projects or organizations.
  • Performance Variability
    The speed and reliability of Docker Hub can sometimes be inconsistent, affecting the performance of operations like image pulls and pushes.
  • Limited Enterprise Features
    Docker Hub may lack some advanced features and integrations needed for enterprise environments, which might require additional tools or services.

Redis vs. KeyDB vs. Dragonfly vs. Skytable | Hacker News
Quick ask: I don’t see “some” of the other offering out there like MemCached… what was the criteria used to select these? I don’t see any source of how the test where run, specs of the systems, how the DB where set up, etc. Would be very valuable to have in order to attempt to re-validate these test on our own platform. I also came back and saw some of your updates...
Memcached vs Redis - More Different Than You Would Expect
So knowing how the difference between Redis and memcached in-memory usage, lets see what this means. Memcached slabs once assigned never change their size. This means it is possible to poison your memcached cluster and really waste memory. If you load your empty memcached cluster with lots of 1 MB items, then all of the slabs will be allocated to that size. Adding a 80 KB...
Redis vs. Memcached: In-Memory Data Storage Systems
Memcached itself does not support distributed mode. You can only achieve the distributed storage of Memcached on the client side through distributed algorithms such as Consistent Hash. The figure below demonstrates the distributed storage implementation schema of Memcached. Before the client side sends data to the Memcached cluster, it first calculates the target node of the...

Why Redis beats Memcached for caching
Both Memcached and Redis are mature and hugely popular open source projects. Memcached was originally developed by Brad Fitzpatrick in 2003 for the LiveJournal website. Since then, Memcached has been rewritten in C (the original implementation was in Perl) and put in the public domain, where it has become a cornerstone of modern Web applications. Current development of...

Docker Hub Reviews

Repository Management Tools
The Docker Hub can be very easily defined as a Cloud repository in which Docker users and partners create, test, store, and also distribute Docker container images. Through the use of Docker Hub, a user can very easily access public, open-source image repositories and at the same time – use the same space to create their own private repositories as well.
