Interpreting A/B test results: false negatives and power

The Netflix TechBlog

We then used simple thought exercises based on flipping coins to build intuition around false positives and related concepts such as statistical significance, p-values, and confidence intervals. As a result, if the test treatment results in a small reduction in the latency metric, it’s hard to successfully identify?

Bring Your Own Cloud (BYOC) vs. Dedicated Hosting at ScaleGrid

Scalegrid

These are advanced cloud configurations that allow you to protect your databases from the internet. At ScaleGrid we recommend you deploy your clusters on private VPC subnets so that your database is not routable from the internet. Deploying your application and database on the same VPC also provides the lowest possible latency path.

A Decade of Dynamo: Powering the next wave of high-performance, internet-scale applications

All Things Distributed

The cloud-hosted version would need to be: Scalable – The service would need to support hundreds of thousands, or even millions of AWS customers, each supporting their own internet-scale applications. Today, DynamoDB powers the next wave of high-performance, internet-scale applications that would overburden traditional relational databases.

Amazon EC2 Cluster GPU Instances - All Things Distributed

All Things Distributed

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. Where to go from here?
