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.

AWS WAF features and specs

  • Scalability
    AWS WAF is designed to scale automatically with your application. It can handle high traffic loads without manual intervention, making it suitable for dynamic and unpredictable environments.
  • Ease of Integration
    AWS WAF easily integrates with other AWS services such as CloudFront, Application Load Balancer, and API Gateway, providing a seamless security solution within the AWS ecosystem.
  • Custom Rule Configuration
    Users can define custom rules and policies to suit specific security requirements. AWS WAF provides a flexible rule creation environment, enabling the creation of complex firewall rules.
  • Managed Rules
    AWS WAF offers a set of pre-configured managed rules that provide protection against common threats such as SQL injection and cross-site scripting, which saves time and effort for administrators.
  • Comprehensive Logging and Monitoring
    AWS WAF integrates with AWS CloudWatch and AWS Kinesis Firehose to provide detailed logging and monitoring capabilities. This helps in tracking, analyzing, and reacting to security events in real time.
  • Cost-Effectiveness
    AWS WAF operates on a pay-as-you-go pricing model, allowing businesses to scale costs with usage. This can be particularly cost-effective for smaller organizations or startups.

Possible disadvantages of AWS WAF

  • Complexity
    While AWS WAF offers powerful features, its setup and configuration can be complex, especially for users who are not familiar with AWS or web security concepts.
  • Initial Learning Curve
    New users may find it challenging to get up to speed with AWS WAF due to the need to understand AWS services and security rules syntax. This initial learning phase can be time-consuming.
  • Rule Processing Latency
    In some cases, the processing of complex rules can introduce latency in response times. This may impact the performance of high-speed applications that require minimal delay.
  • Service Dependency
    AWS WAF is deeply integrated within the AWS ecosystem. As a result, its effectiveness is dependent on the use of other AWS services, which may not be ideal for multi-cloud strategies.
  • Cost for Heavy Usage
    While the pay-as-you-go model can be cost-effective for small-scale operations, businesses with high traffic volumes might find the cumulative costs to be significant.
  • Limited Offline Capabilities
    AWS WAF is designed primarily for protecting online applications. Offline or on-premise applications require different solutions, and AWS WAF may not be well-suited in these scenarios.

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...
