Feed: Neo4j Graph Data Platform. Author: Yolande Poirier. Graph Data Science features are now available in Bloom 2.3! Just select the Graph Data Science icon and choose from the available algorithms. The GDS plugin needs to be installed on the database for self-managed users, or you can use AuraDS. To get an idea of what Bloom and Graph Data Science are capable of, read Zach Blumenfeld ’s blog on using graph technology on a freight forwarding logistics network. In this first blog in the series, he gets us started with experimentation and visualization of supply chain data using ... Read More

Feed: Neo4j Graph Data Platform. Author: Yolande Poirier. We are very proud to announce the 2022 Neo4j Connected Data Fellowship in partnership with the International Consortium of Investigative Journalists (ICIJ). The fellowship, first initiated in 2017, is inspired by the ability of graph databases to strengthen reporting and help journalists understand large datasets. This technology was essential in uncovering ICIJ’s prize-winning investigations, including the Panama Papers, Pandora Papers, and the FinCEN Files. The 2022 fellowship brings an independent, dedicated data scientist to work with the ICIJ to help make sense of complex data and promote greater transparency. The ICIJ ... Read More

Feed: Neo4j Graph Data Platform. Author: Yolande Poirier. A new course is available on GraphAcademy for Building Neo4j Applications with Java! Michael Hunger and I collaborated to create a hands-on course that starts with a project skeleton and guides users through writing code to build a completed IMDB-clone application with Neo4j and Java. In the app, we can store and query users, movies, genres, people, and user favorites. The data that feeds the fully-fledged application includes the MovieLens recommendation dataset, augmented with themoviedb.org movie and cast data. Data results are presented to the user through a beautiful webpage supported ... Read More

Feed: AWS Compute Blog. Author: Marcia Villalba. This post is written by Christian Müller, Principal AWS Solutions Architect and Maximilian Schellhorn, AWS Solutions Architect When running applications on AWS Lambda, you have the option to use either one of the managed runtime versions that AWS provides or bring your own custom runtime. The following blog post provides a walkthrough of how you can create and optimize a custom runtime for Java based Lambda functions. Builders might rely on customized or experimental runtime behavior when creating solutions in the cloud. The Java ecosystem fosters innovation and encourages experiments with the current ...

Feed: AWS Compute Blog. Author: Benjamin Smith. This post is written by Mark Sailes, Senior Specialist Solutions Architect. This blog post shows how to optimize the performance of AWS Lambda functions written in Java, without altering any of the function code. It shows how Java virtual machine (JVM) settings affect the startup time and performance. You also learn how you can benchmark your applications to test these changes. When a Lambda function is invoked for the first time, or when Lambda is horizontally scaling to handle additional requests, an execution environment is created. The first phase in the execution environment’s ... Read More

Feed: AWS Compute Blog. Author: Rick Armstrong. This post is written by: Bill Chan, Enterprise Solutions Architect According to a report from Grand View Research, “the global application server market size was valued at USD 15.84 billion in 2020 and is expected to expand at a compound annual growth rate (CAGR) of 13.2% from 2021 to 2028.” The report also suggests that Java based application servers “accounted for the largest share of around 50% in 2020.” This means that many organizations continue to rely on Java application server capabilities to deliver middleware services that underpin the web applications running their ...

Feed: AWS Compute Blog. Author: Julian Wood. This post is written by Dhiraj Mahapatro, Senior Specialist SA, Serverless and Christian Mueller, Principal Solutions Architect Modern secure applications establish network connections to other services through HTTPS. This ensures that the application connects to the right party and encrypts the data before sending it over the network. You might not want unauthenticated users to connect to your service as a service provider. One solution to this requirement is to use mutual TLS (Transport Layer Security). Mutual TLS (or mTLS) is a common security mechanism that uses client certificates to add an authentication ... Read More
