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: Sebastian Estevez. Yesterday at ApacheCon, our very own Patrick McFadin announced the public preview of an open source tool that enables developers to run their AWS DynamoDB™ workloads on Apache Cassandra. With the DataStax Proxy for DynamoDB and Cassandra, developers can run DynamoDB workloads outside of AWS (including on premises, in other clouds, and in hybrid configurations). The Big Picture The cloud has changed computing forever, and as cloud services continue to evolve up the stack, the new capabilities they offer developers come with trade-offs. One of the trade-offs developers, architects, and ... Read More

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. Attend the Strata Data Conference in New York, September 23-26 to learn how ML, AI, and data are converging. The Strata Data Conferences helped chronicle the birth of big data, as well as the emergence of data science, streaming, and machine learning (ML) as disruptive phenomena. Strata attracts the leading names in the fields of data management, data engineering, analytics, ML, and artificial intelligence (AI). For nearly a decade, it’s provided a venue for developers, data and ML engineers, data architects, data scientists, and others to acquire or hone skills, explore provocative ideas, and network ...

Feed: AWS Compute Blog. Author: Rachel Richardson. This post is courtesy of Wallace Printz, Senior Solutions Architect, AWS, and Christian Mueller, Senior Solutions Architect, AWS.Many cloud-native application architectures take advantage of the point-to-point and publish-subscribe (“pub-sub”) model of message-based communication between application components. This architecture is generally more resilient to failure because of the loose coupling and because message processing failures can be retried. It’s also more efficient because individual application components can independently scale up or down to maintain message-processing SLAs, compared to monolithic application architectures. Synchronous (REST-based) systems are tightly coupled. A problem in a synchronous downstream dependency has an ... Read More

Feed: Microsoft Azure Blog. Author: Tyler Fox. This is the fourth blog post in a four-part series on monitoring on Azure HDInsight. Monitoring on Azure HDInsight Part 1: An Overview discusses the three main monitoring categories: cluster health and availability, resource utilization and performance, and job status and logs. Part 2 is centered on the first topic, monitoring cluster health and availability. Part 3 discussed monitoring performance and resource utilization. This blog covers the third of those topics, workload metrics and logs, in more depth. During normal operations when your Azure HDInsight clusters are healthy and performing optimally, you will likely ... Read More

Feed: AWS Compute Blog. Author: Ignacio Riesgo. This post is contributed by Mahmoud ElZayet | Specialist SA – Dev Tech, AWS Modern application development processes enable organizations to improve speed and quality continually. In this innovative culture, small, autonomous teams own the entire application life cycle. While such nimble, autonomous teams speed product delivery, they can also impose costs on compliance, quality assurance, and code deployment infrastructures. Standardized tooling and application release code helps share best practices across teams, reduce duplicated code, speed on-boarding, create consistent governance, and prevent resource over-provisioning. Overview In this post, I show you how to ... Read More
