As data grows exponentially, the modern Hadoop ecosystem provides not only a reliable distributed aggregation system that delivers data parallelism, but also analytics for great data insights. In this article Monica Beckwith, starting from core Hadoop components, investigates the design of a highly available, fault tolerant Hadoop cluster, adding security and data-level isolation.
The new “Hadoop in Practice. Second Edition” book by Alex Holmes provides a deep insight into Hadoop ecosystem covering a wide spectrum of topics such as data organization, layouts and serialization, data processing, including MapReduce and big data patterns, special structures along with their usage to simplify big data processing, and SQL on Hadoop data.
This series takes the reader on a journey from determining the business case for APIs to a design methodology, meeting implementation challenges and maintaining public APIs on the Web over time.
Datameer, a big data analytics application for Hadoop, introduced Datameer 5.0 with Smart Execution to enhance the data analytics. InfoQ spoke with Matt Schumpert from Datameer about the new product.
Our understanding of SOA has changed over the last 15 years. We review and update the Principles of Service Orientation providing a more business-focused & less technology-specific perspective. 6
Ganesh Prasad proposes separating governance and management in SOA projects to make sure that right dependencies are used throughout the system in order to promote agility and reduce costs and risks.
What are the practical concerns associated with running microservice systems? And what you need to know to embrace the power of smaller services without making things too hard? 2
Many Web API designers claim their are RESTful, but their APIs have little in common with REST. What can be done to make a web service API truly RESTful? 8
Sytze Harkema explains how to save and retrieve relational SQL data into a NoSQL key-value store as implemented by FoundationDB, an open source, scalable, fault tolerant and ACID database.
In this article, authors discuss Model Driven Engineering (MDE) practice based on a survey and found that developers use MDE to develop key parts of a system instead of generating whole systems.
Ganesh Prasad proposes minimizing service dependencies in a SOA implementation rather than avoiding point-to-point connections in order to obtain a more flexible system that can evolve over time.
