Feed: Redis. Author: Redis Growth Team. Citi Bike remains the nation’s favorite bike share program. With over 20,000 bikes scattered across Manhattan, Brooklyn, Queens, and the Bronx, getting from A to B has never been easier. It’s cheap, it’s convenient and it’s green. And most notably, it’s popular. Thanks to this Launchpad App, you’re now able to discover how many bikes are used at different times, throughout each day, in different neighborhoods across the city.  Despite New York offering other modes of transport, those who are committed to a healthier and greener way of living can plan their trips in ...

Feed: AWS Architecture Blog. Event driven programs use events to initiate succeeding steps in a process. For example, the completion of an upload job may then initiate an image processing job. This allows developers to create complex architectures by using the principle of decoupling. Decoupling is preferable for many workflows, as it allows each component to perform its tasks independently, which improves efficiency. Examples are ecommerce order processing, image processing, and other long running batch jobs. Amazon Simple Storage Service (S3) is an object-based storage solution from Amazon Web Services (AWS) that allows you to store and retrieve any amount ... Read More

Feed: CIO. Author: . Data mining definitionData mining, sometimes used synonymously with “knowledge discovery,” is the process of sifting large volumes of data for correlations, patterns, and trends. It is a subset of data science that uses statistical and mathematical techniques along with machine learning and database systems. The Association for Computing Machinery’s Special Interest Group on Knowledge Discovery and Data Mining (SigKDD) defines it as the science of extracting useful knowledge from the huge repositories of digital data created by computing technologies.The idea of extracting patterns from data is not new, but the modern concept of data mining began ...

Feed: Blog – Hazelcast. Author: Neil Stevenson. It’s said a wise person learns from their mistakes, and a wiser person learns from the mistakes of others. In this blog, we’ll look at some common mistakes made when deploying Hazelcast, so you can avoid them and be that wiser person. In other words, what are the “anti-patterns” that don’t ensure failure, but do make problems more likely? Here we’ll look at the top 5. The good news is it’s not a top 10. The following 5 are the ones we see the most. 1. A 2-Node Cluster Hazelcast is a distributed ... Read More

Feed: Blog – ArangoDB. Author: Vaidas Gasiunas. This article presents a case study of using AQL queries for detecting complex money laundering and financial crime patterns. While there have been multiple publications about the advantages of graph databases for fraud detection use cases, few of them provide concrete examples of implementing detection of complex fraud patterns that would work in real-world scenarios.  This case study is based on a third-party transaction data generator, which is designed to simulate realistic transaction graphs of any size. The generator disguises complex financial fraud patterns of two kinds:  Circular money flows: a big amount ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: David Johnsen. Customer IoT applications require rapid over the air (OTA) updates to maintain the state of their IoT things. This becomes increasingly important as IoT fleets grow. Jobs for AWS IoT Device Management is a feature to push updates to targeted edge devices. Each job targets devices in static or dynamic AWS IoT thing groups. Static thing groups include a set of specified IoT things while dynamic thing groups contain things that match a specified query and automatically update if things are added that match this query. This ... Read More

Feed: AWS Big Data Blog. AWS customers often segment their workloads across accounts and Amazon Virtual Private Cloud (Amazon VPC) to streamline access management while being able to expand their footprint. As a result, in some scenarios you, as an AWS customer, need to make an Amazon Managed Streaming for Apache Kafka (Amazon MSK) cluster accessible to Apache Kafka clients not only in the same Amazon VPC as the cluster but also in a remote Amazon VPC. A guest post by Goldman Sachs presented cross-account connectivity patterns to an MSK cluster using AWS PrivateLink. Inspired by the work of Goldman ... Read More

Feed: AWS Compute Blog. Author: Talia Nassi. Amazon DynamoDB is a fully managed, serverless NoSQL database. In this post, you learn about the different DynamoDB patterns used in serverless applications, and use the recently launched Serverless Patterns Collection to configure DynamoDB as an event source for AWS Lambda. Benefits of using DynamoDB as a serverless developer DynamoDB is a serverless service that automatically scales up and down to adjust for capacity and maintain performance. It also has built-in high availability and fault tolerance. DynamoDB provides both provisioned and on-demand capacity modes so that you can optimize costs by specifying capacity per ... Read More

Feed: AWS Compute Blog. Author: Talia Nassi. The recently launched Serverless Patterns Collection is a repository of serverless examples that demonstrate integrating two or more AWS services. Each pattern uses either the AWS Serverless Application Model (AWS SAM) or AWS Cloud Development Kit (AWS CDK). These simplify the creation and configuration of the services referenced. The Serverless Patterns Collection is both an educational resource to help developers understand how to join different services, and an aid for developers that are getting started with building serverless applications. By using these patterns, you can experience first-hand what is possible in the realm of ... Read More
