Feed: AWS Big Data Blog. Perimeter security helps secure Apache Hadoop cluster resources to users accessing from outside the cluster. It enables a single access point for all REST and HTTP interactions with Apache Hadoop clusters and simplifies client interaction with the cluster. For example, client applications must acquire Kerberos tickets using Kinit or SPNEGO before interacting with services on Kerberos enabled clusters. In this post, we walk through setup of Apache Knox to enable perimeter security for Amazon EMR clusters.It provides the following benefits: Simplify authentication of various Hadoop services and UIs Hide service-specific URLs/Ports by acting as a Proxy Enable SSL ...

Feed: Blog Post – Corporate – DataStax. Author: Louise Westoby, Senior Director, Product Marketing. Historically, software was monolithic. In most cases, development teams would have to rewrite or rebuild an entire application to fix a bug or add a new feature. Building applications with any sense of speed or agility was largely out of the question, which is why software suites like Microsoft Office were generally released once a year. Much has changed over the last decade or so. In the age of lightning-fast networks and instant gratification, leading software development teams are adopting DevOps workflows and prioritizing CI/CD so ... Read More

Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. Almost a decade ago, Neo4j took off as a transactional graph database management platform. Just a year after its initial launch, a new, powerful query language called Cypher was introduced to allow expressive, efficient querying and other interactions with the graph data in Neo4j. Today, Neo4j supports graph analytics including implementation of a wide variety of state-of-the-art graph algorithms with custom optimizations for Neo4j’s graph database model. It achieves unmatched performance in scalability, routinely running millions or even billions of nodes and edges.The next natural step for the platform in 2019 is ... Read More

Feed: Radar. Author: Mac Slocum. Both quantitatively and qualitatively, the Radar team has uncovered a growing wave of change in software development and architectural trends. Organizations are increasingly choosing the combination of cloud, containers, and orchestration to implement microservices as their directional architecture. The need to support business processes and customer expectations—and to have flexibility, adaptability, and scaling for new projects and for migrating legacy systems—has organizations embracing the interrelated technologies and approaches we call Next Architecture. In this report, we cover background, technology and business drivers, and key components that define the Next Architecture concept. Every company has a ... Read More

Feed: Oracle Blogs | Oracle Blogs. The machine learning expertise at Oracle isn’t concentrated in a single department or R&D effort, it’s dispersed all over the world. That was made clear recently when more than 250 of the company’s experts spent three days together at Oracle headquarters for a machine-learning summit. It took an hour just to get through a lightning-round of introductions at one minute per team. “We represent the oldest profession in the world,” joked one engineer introducing his team. “I’m talking about construction, the tools that help the pharaohs build the pyramids.” Seemingly every vertical market, from ...

Feed: Blog – Hazelcast. Author: Rafal Leszko. I’m sure you use caching somewhere in your system. This can be either to improve performance, reduce backend load, or to decrease downtime. Everybody uses caching. Caching is everywhere. However, in which part of your system should it be placed? If you look at the following diagram representing a simple microservice architecture, where would you draw the “cache” rectangle? There is more than one right answer to this question. You could place the cache inside each service or as a completely separate cache server. You could also put it in front of each ... Read More

Feed: Planet PostgreSQL. If you’re like me, understanding SQL is taking you a long time. And some efforts. It took me years to get a good mental model of how SQL queries are implemented, and then up from the lower levels, to build a mental model of how to reason in SQL. Nowadays, in most case, I can think in terms of SQL and write queries that will give me the result set I need. In most cases, because some parts of SQL are still complex, and I don’t practice as much as I used to. In particular, newer PostgreSQL ... Read More

Feed: Recent Announcements. Today, PySpark and SparkR users must install their dependencies on each host in a cluster. As a result, teams operating multi-tenant clusters struggle to keep up with specific library versions and manage dependencies, limiting developer productivity, increasing the time spent preparing a cluster for use, and adding complexity to cluster upgrades.  Using Hadoop 3, Docker, and EMR, Spark users no longer have to install library dependencies on individual cluster hosts, and application dependencies can now be scoped to individual Spark applications. This is achieved by running Spark applications in Docker containers instead of directly on EMR cluster ... Read More
