Feed: AWS Architecture Blog. Organizations across every industry and sector are looking to easily and cost-effectively process vast amounts of data. Amazon EMR offers a way to instantly provision as much or as little capacity as needed to perform data- intensive tasks. When launching Amazon EMR, the IPs of the primary (master) and core node are automatically assigned at the starting point. However, you may need to set up static private IPs for an Amazon EMR cluster to connect to systems within your on-premises data center. For example, if your on-premises data center has firewall policies set to allow access ... Read More

Feed: Planet MySQL; Author: Continuent; First off: Happy 15th birthday, Hadoop! It wasn’t an April Fool’s joke then, and it isn’t today either: Hadoop’s initial release was on the 1st of April 2006 :-) As most of you will know, Apaches Hadoop is a powerful and popular tool, which has been driving much of the Big Data movement over the years. It is generally understood to be a system that provides a (distributed) file system, which in turn stores data to be used by applications without knowing about the structure of the data. In other words, it’s a file system ... Read More

Feed: AWS Big Data Blog. This post is co-written by Mei Long at Upsolver.  Software as a service (SaaS) based applications are in demand today, and customers have growing need for adopting many of them in their use cases.

Feed: Featured Blog Posts - Data Science Central. Author: Varvara Masalitina. How extensive must data sets be to be considered as big data? For some, a slightly larger Excel spreadsheet is “big data”. Fortunately, there are certain characteristics that allow us to describe big data pretty well. According to IBM, 90% of the data that exists worldwide today was created in the last 2 years alone. Big Data Analysis in Healthcare could be helpful in many ways. For example, such analyzes may also counteract the spread of diseases and optimize the needs-based supply of medicinal products and medical devices. In ... Read More

Feed: Planet PostgreSQL. 29 Mar Is Greenplum Database “just a big sharded PostgreSQL”? Post Views: 641IntroductionWhat is Greenplum Database? This is on of PostgreSQL forks optimized for OLAP and analytics workloads. In my opinion the second life of GreenplumDB began in 2015 year. In this year Greenplum became the open source project. The current 6 version based on PostgreSQL 9.4, and the Greenplum Community is actively developing the 7 version, which should be compatible with PostgreSQL 13! So, this is really cool! But what prompted me to write this article? The fact is that sometimes we are confronted with the opinion ... Read More

Feed: Actian. Author: Jeremy Hankinson. On-Premise, you’re groundedThe emergence of the Hadoop Distributed File System (HDFS) and the ability to create a data lake of such unprecedented depths – on standard hardware no less! – was such a breakthrough that the administrative pain and the hardware costs involved with building out an HDFS-based analytic solution were acceptable casualties of innovation. Today, though, with an analytic tool like Actian Avalanche containerized, running in the cloud, and taking advantage of Google Kubernetes Engine (GKE), there’s no reason to put up with those pains. Indeed, because Avalanche on GKE treats compute and storage ... Read More
