The new database is opening up significant career opportunities for data modelers, admins, architects, and data scientists. In parallel, it’s transforming how businesses use data. It’s also making the traditional RDBMS look like a T-REX.
Our web-centric, social media, and internet-of-things are acting as a sea-change to break traditional data design and management approaches. Data is coming in at increasing speeds, and 80% of it cannot be easily organized into the neat little rows and columns associated with the traditional RDBMS.
Mobile Location Based Services are on the rise. After several false starts back in the mid 2000s, every mobile user now depends on their phones to tell them where they are, where their friends are, and to engage with social media like Facebook and Foursquare. A report by Juniper Research suggests this market is expected to breach over $12 billion next year, where it hardly existed a few years ago at all.
This is in part because mobile apps have become ubiquitous now. In order to remain relevant, businesses need to interact socially and have a web store to remain accessible to their wandering customers.
Building a geographically aware application from scratch sounds daunting and like a lot of initial data setup. It doesn’t have to be. Products like vFabric Postgres (vPostgres) can be used along with the PostGIS extensions to perform geographic-style queries. Then, public data and an open source visualizer can be used to transform the query into a meaningful result for your application or end user.
By using RabbitMQ, SockJS, Cowboy, Erlang, and more, his team built a highly scalable, customizable solution for real-time comments based on websockets. His talk, Realtime Web @ HuffingtonPost, was for developers of real-time, Erlang-based solutions—he covered architecture, lessons learned, pitfalls, and future improvements. The presentation objectives included:
Why they went with Erlang and SockJS for the commenting platform
How they integrated RabbitMQ routing to power the subscription architecture
How they managed subscriptions for real time channels
Their plans to extend the framework into an open source solution
Where they want other mechanisms for publishing comments outside of RabbitMQ Continue reading →
Two of the hottest topics in technology today are “mobile” and “cloud.” They are at the top of most CTOs list of objectives, yet they also seem to be the ones most shrouded in mystery. So where do you start?
This past year, at VMworld 2012 San Francisco and Barcelona, I ran a session where we built a complete database-backed web application from scratch using the SpringSource Tool Suite and the Grails framework for Java. Then, we published the application to Cloud Foundry—our open Platform-as-a-Service offering. Finally, we proceeded to build a mobile application that consumed the data from the web application built earlier. I broke a cardinal rule by doing the entire session live, but it all went off without a hitch and audience participation with the application was an absolute blast. By the time we were done, we had built two applications from the ground up, and folks had an application that looked, smelled, and tasted like a native mobile application running on their phones. And, we did all of this in less than one hour! Continue reading →
In this article (and demonstration further below), we will show you six steps that give you an idea of how easy it is to provision using VAS. We will show you how to install VAS and use it to provision vFabric tc Server across three nodes along with a WAR file. The explanation below refers to examples from RubyGems.org and GitHub/vFabric/VAS-Ruby-API along with the latest VAS documentation.
To put it simply, vFabric Application Director (AppD) automates deployments. That might sound trivial at first, but it can automate an entire deployment for all the tiers of complex application, in the right order, with the right configurations, across multiple cloud and/or virtual infrastructures, and without ANY human intervention. If you are just hearing about AppD, you can learn about it quickly here:
