In just three short years, Amazon DynamoDB has emerged as the backbone for many powerful Internet applications such as AdRoll , Druva , DeviceScape , and Battlecamp. You can enable the DynamoDB Streams feature for a table with just a few clicks using the AWS Management Console, or you can use the DynamoDB API. DynamoDB Streams.

I had my website with funny photos and links to favorite websites live on the internet, and better yet, I could edit directly on the server. It’s safe to say WordPress, the platform now powering 40% of the internet, won that battle, but MovableType paved the way for Jamstack CMSs in the future. But, when it worked, it was magical.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. In exchange, your team gains maintainability and developer efficiency, of course. But this consideration needs to be deliberate. Still, it’s not that difficult , and its support is coming, e.g. it’s available since Apache 2.4.26.

In fact, this is been proven by our customers as Amazon Aurora remains the fastest growing service in AWS history. We are increasingly seeing customers wanting to build Internet-scale applications that require diverse data models. The opposite is true. What we experienced at Amazon.com was using a database beyond its intended purpose.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.

Three years ago, as part of our AWS Fast Data journey we introduced Amazon ElastiCache for Redis , a fully managed in-memory data store that operates at sub-millisecond latency. ElastiCache for Redis Multi-AZ capability is built to handle any failover case for Redis Cluster with robustness and efficiency.

For example, the most fundamental abstraction trade-off has always been latency versus throughput. Modern CPUs strongly favor lower latency of operations with clock cycles in the nanoseconds and we have built general purpose software architectures that can exploit these low latencies very well.Â
