Revolution Analytics is proud to announce the latest update to our enhanced, production-grade distribution of R, Revolution R Enterprise. This update expands the range of supported computation platforms, adds new Big Data predictive models, and updates to the latest stable release of open source R (2.14.2), which improves performance of the R interpreter by about 30%.
This release expands the range of big-data statistical analysis with support for Generalized Linear Models (GLM). Logistic (Binomial) Poisson, Gamma and Tweedie models are all supported with a high-performance C++ implementation, and you can also model any distribution in the GLM family with a custom link function written in R. Big Data GLM has been a common request from many of our customers, and beta testers have been blown away by the speed of the implementation. For example here's an example of a Tweedie regression on 8.5 million insurance claims in less than 2 and a half minutes (skip ahead to 1:10 for the demo):
We can make these computations fast by streaming data through the CPU instead of loading it all at once (which also means no data-size limitations), and by distributing the computations across multiple processors on a server or multiple nodes in a cluster. Revolution R Enterprise 6.0 now supports Linux-based clusters running IBM's Platform LSF grid software, in addition to clusters running Microsoft HPC Server. And with HPC server, you can now run big-data analytics in the Azure Cloud, as shown in this demo.
One other new feature relates to accessing data. Revolution R Enterprise has always included our XDF data format: a high-performance local filestore for Big Data in R. Making a local copy of data in XDF is a very useful if you plan to analyze the same data several times, and want to avoid the network latency of copying the data over and over. But if you don't need a local copy, you can now use the RevoScaleR data step and big-data algorithms on the source data (SAS, SPSS, ASCII or ODBC) directly. (By the way, you don't need a SAS or SPSS license to access data files in those formats, which is useful if you've switched to an R-only environment.) For example, here's an analysis of commuter behavior from 2010 NYC Community Health Survey working directly from the source SAS file:

If testing environments are constantly unavailable and affected by outages, release timelines will be affected. You can use three metrics to measure stability events for specific environments and plan around events that will affect your critical path to release.
DevOps failure is a touchy subject with some, because DevOps is typically perceived as a way to avoid failure. As a result, when you fail in a DevOps practice, the situation can seem almost hopeless. However, just as a fail-fast business approach, or the “fail and adjust sooner” methodology of Agile often proves, DevOps failures are actually a step in the right direction. They’re the first step toward learning from failures and turning your DevOps practice into one that will lead you toward even...
Every year about this time, we gaze into crystal balls to divine the future of our industry – or at least where it’s headed over the next 365 days. The result is often a triumph of incrementalism: we predict that we will get more of what we already have. The truth is, technology isn’t as revolutionary as we often think – and commenting on incremental changes alone may not help us understand what lies ahead.
Along with a few near-term predictions – so hard to resist – I’d also like to make some ...
The goal of Microservices is to improve software delivery speed and increase system safety as scale increases. Microservices being modular these are faster to change and enables an evolutionary architecture where systems can change, as the business needs change. Microservices can scale elastically and by being service oriented can enable APIs natively. Microservices also reduce implementation and release cycle time and enables continuous delivery. This paper provides a logical overview of the Mi...
In this article, we'll cover how you can monitor an application that runs on the Java Virtual Machine by going over some of the critical metrics you need to track. And, as a monitoring tool, we'll use Stackify Retrace, a full APM solution.
The application we'll monitor to exemplify these metrics is a real-world Java web application built using the Spring framework. Users can register, login, connect their Reddit account and schedule their posts to Reddit.
How is DevOps going within your organization? If you need some help measuring just how well it is going, we have prepared a list of some key DevOps metrics to track. These metrics can help you understand how your team is doing over time.
The word DevOps means different things to different people. Some say it a culture and every vendor in the industry claims that their tools help with DevOps. Depending on how you define DevOps, some of these metrics may matter more or less to you and your team.
For many of us laboring in the fields of digital transformation, 2017 was a year of high-intensity work and high-reward achievement. So we’re looking forward to a little breather over the end-of-year holiday season.
But we’re going to have to get right back on the Continuous Delivery bullet train in 2018. Markets move too fast and customer expectations elevate too precipitously for businesses to rest on their laurels.
Here’s a DevOps “to-do list” for 2018 that should be priorities for anyone w...
As we head into a new year, IT improvements and management should be top of mind for any business looking to amp up their customer experience, delivery and service in 2018. Recently, at CA World ‘17, I talked about how every business strategy is now an IT strategy. With that in mind, I have a few predictions for 2018 that I encourage companies to have on their to-do list as they look to find greater success in the new year.

The Toyota Production System, a world-renowned production system is based on the "complete elimination of all waste". The "Toyota Way", grounded on continuous improvement dates to the 1860s. The methodology is widely proven to be successful yet there are still industries within and tangential to manufacturing struggling to adopt its core principles:
Jidoka: a process should stop when an issue is identified prevents releasing defective products
We seem to run this cycle with every new technology that comes along. A good idea with practical applications is born, then both marketers and over-excited users start to declare it is the solution for all or our problems. Compliments of Gartner, we know it generally as “The Hype Cycle”, but each iteration is a little different.
2018’s flavor will be serverless computing, and by 2018, I mean starting now, but going most of next year, you’ll be sick of it. We are already seeing people write such...
Defining the term ‘monitoring’ is a difficult task considering the performance space has evolved significantly over the years. Lately, there has been a shift in the monitoring world, sparking a healthy debate regarding the definition and purpose of monitoring, through which a new term has emerged: observability. Some of that debate can be found in blogs by Charity Majors and Cindy Sridharan. 
When shopping for a new data processing platform for IoT solutions, many development teams want to be able to test-drive options before making a choice. Yet when evaluating an IoT solution, it’s simply not feasible to do so at scale with physical devices. Building a sensor simulator is the next best choice; however, generating a realistic simulation at very high TPS with ease of configurability is a formidable challenge. When dealing with multiple application or transport protocols, you would be...
It’s “time to move on from DevOps and continuous delivery.”
This was the provocative title of a recent article in ZDNet, in which Kelsey Hightower, staff developer advocate at Google Cloud Platform, suggested that “software shops should have put these concepts into action years ago.”
Reading articles like this or listening to talks at most DevOps conferences might make you think that we’re entering a post-DevOps world. But vast numbers of organizations still struggle to start and drive transfo...
The end of the year is a time for reflection. It’s when most of us are looking back at the choices, accomplishments, and mistakes of the year prior and setting goals to improve the following year. It’s also when businesses analyze the year’s trends and behaviors to determine necessary strategic changes to be made; however, if you aren’t analyzing the right metrics, such reflection is a useless effort.
Below is an excerpt from an article provided by Elad Rave, founder and CTO of Teridion, explai...
Let's do a visualization exercise. Imagine it's December 31, 2018, and you're ringing in the New Year with your friends and family. You think back on everything that you accomplished in the last year: your company's revenue is through the roof thanks to the success of your product, and you were promoted to Lead Developer. 2019 is poised to be an even bigger year for your company because you have the tools and insight to scale as quickly as demand requires. You're a happy human, and it's not just...
