As builders and developers, many of us are aware of the principle of Don’t Repeat Yourself (or DRY) and practice it every day. Entire runtimes and programming languages have been developed by taking that principle to an even higher level, with the core idea of writing software once and having it run on many different […]

The Amazon Corretto team introduces the open source Heapothesys benchmark, a synthetic workload that simulates fundamental application characteristics that affect garbage collector (GC) latency. The benchmark creates and tests GC load scenarios defined by object allocation rates, heap occupancy, and JVM flags, then reports the resulting JVM pauses. OpenJDK developers can thus produce reference points […]

Many AWS customers—startups and large enterprises—are on a path to adopt machine learning and deep learning in their existing applications. The reasons for machine learning adoption are dictated by the pace of innovation in the industry, with business use cases ranging from customer service (including object detection from images and video streams, sentiment analysis) to […]

As the dust settles after another re:Invent closes, I wanted to put together a quick summary of all the open source-related announcements that happened in the run up to this year’s re:Invent and the week itself. If you are interested in open source in mobile web development, devops, containers, security, big data and data analytics, […]

Amazon runs thousands of Java production services; both we and our customers depend heavily on  various distributions of the JDK (Java Development Kit). In 2016 we started building Amazon Corretto, our OpenJDK binary distribution, and started using it to run AWS and other Amazon services. In 2018, we open sourced Corretto and made it available […]

Optimizing the size of Docker images has several benefits. One of these is faster deployment times, which is very important if your application needs to scale out quickly to respond to an unexpected traffic burst. In this post, I’ll show you an interesting approach for optimizing Docker images for Java applications, which also helps to […]
