"Introduction In the modern era, software is commonly delivered as a service: called web apps, or software-as-a-service. The twelve-factor app is a methodology for building software-as-a-service apps that: Use declarative formats for setup automation, to minimize time and cost for new developers joining the project; Have a clean contract with the underlying operating system, offering maximum portability between execution environments; Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration; Minimize divergence between development and production, enabling continuous deployment for maximum agility; And can scale up without significant changes to tooling, architecture, or development practices. The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc). Background The contributors to this document have been directly involved in the development and deployment of hundreds of apps, and indirectly witnessed the development, operation, and scaling of hundreds of thousands of apps via our work on the Heroku platform. This document synthesizes all of our experience and observations on a wide variety of software-as-a-service apps in the wild. It is a triangulation on ideal practices for app development, paying particular attention to the dynamics of the organic growth of an app over time, the dynamics of collaboration between developers working on the app's codebase, and avoiding the cost of software erosion. Our motivation is to raise awareness of some systemic problems we've seen in modern application development, to provide a shared vocabulary for discussing those problems, and to offer a set of broad conceptual solutions to those problems with accompanying terminology. The format is inspired by Martin Fowler's books Patterns of Enterprise Application Architecture and Refactoring. Who should

Bueno. Eso. Compartí el que me di cuenta que puso antes Pablo en vez del original por error, pero la idea entre ambos, si la obviedad es tolerable, es idéntica :) Está muy bien estructurado en cuanto que cada factor depende de los demás a la vez que los promueve. Permite un enfoque general que incluye prácticas de arquitectura - y de armado cotidiano de productos - que posibilitan llegar donde yo entiendo - según me voy enterando - que es el lugar a donde llegar. Sin embargo, creo que ni éste departamento en sus sistemas más nuevos cumple todos y cada uno de aquellos factores. Esto, lejos de ser una crítica, es una invitación para que revisemos si es el único método posible - cosa improbabilísima - o el mejor método - también bastante improblable - a seguir. Lo que sí sostengo como un absoluto - quien no lo haría - es que es un método practicable. Mi aporte mínimo es defenderlo como uno bueno.

"OpenStack and Docker will continue to dominate the open source cloud discussion. But Docker may prove to gain the most as it is also breeding a diverse ecosystem of open source projects. OpenStack is primarily contained (no pun intended) to the development of its own cloud operating system. It does integrate with OpenShift, for example, but for the most part the different groups within OpenStack do the lion's share of development. Docker's influence is such that it is affecting the overall open source community. The projects that are closely tied to Docker, such as Ansible, will continue to grow as developers seek tools to use with the fast growing container technology."

"The Cloudera Development Kit, or CDK for short, is a set of libraries, tools, examples, and documentation focused on making it easier to build systems on top of the Hadoop ecosystem. The goals of the CDK are: Codify expert patterns and practices for building data-oriented systems and applications. Let developers focus on business logic, not plumbing or infrastructure. Provide smart defaults for platform choices. Support piecemeal adoption via loosely-coupled modules."

"Apache Giraph is an iterative graph processing system built for high scalability. For example, it is currently used at Facebook to analyze the social graph formed by users and their connections. Giraph originated as the open-source counterpart to Pregel, the graph processing architecture developed at Google and described in a 2010 paper. Both systems are inspired by the Bulk Synchronous Parallel model of distributed computation introduced by Leslie Valiant. Giraph adds several features beyond the basic Pregel model, including master computation, sharded aggregators, edge-oriented input, out-of-core computation, and more. With a steady development cycle and a growing community of users worldwide, Giraph is a natural choice for unleashing the potential of structured datasets at a massive scale."

"But when Mark Russinovich, Microsoft's CTO for Azure, took the stage at Build 2015 in San Francisco Wednesday morning to demonstrate how containerized microservices applications work in Windows Server. [...] As is his wont, he dove right in to a demonstration of using Docker Build (on a PowerShell command line) to package and deploy an ASP.NET web site as a Docker container. [...] He took only a few seconds to package the web site into a container image, then he ran the package with the docker run command. [...] And then he paused, took the temperature of the room, and may have recognized that Windows developers may have been completely confused by what they were seeing. [...] So Russinovich asked for a show of hands of folks in the room who might have heard of something called Linux. (Don't worry, he's done this before.) [...] He then used a new build of Visual Studio, running in Windows, to publish the container to the Linux host. He then proceeded to debug the running Linux app, including setting a remote breakpoint, from Visual Studio. [...] Without saying so explicitly, Mark Russinovich was obsoleting much of Windows Server before developers' eyes."

"Figaro is a probabilistic programming language that supports development of very rich probabilistic models and provides reasoning algorithms that can be applied to models to draw useful conclusions from evidence. Both model representation and reasoning algorithm development can be challenging tasks. Figaro makes it possible to express probabilistic models using the power of programming languages, giving the modeler the expressive tools to create a wide variety of models. Figaro comes with a number of built-in reasoning algorithms that can be applied automatically to new models. In addition, Figaro models are data structures in the Scala programming language, which is interoperable with Java, and can be constructed, manipulated, and used directly within any Scala or Java program."

"Comdb2 is a relational database built in-house at Bloomberg L.P. over the last 14 years or so. It started with a modest goal of replacing an older home-grown system to allow databases to stay in sync easier. SQL was added early in its development, and it quickly started replacing other relational databases in addition to its original goal. Comdb2 today holds a good chunk of Bloomberg's data, and is continually developed by a dedicated team."

Jasmine is a behavior-driven development framework for testing JavaScript code.

Data.js is a data representation framework for Javascript. It is being developed in the context of Substance, a web-based document authoring and publishing engine. It took some inspiration from various existing libraries such as the Google Visualization API or Underscore.js.  You can report bugs and discuss features on the GitHub issues page, on Freenode IRC in the #_substance chann el, post questions to the Google Group, or send tweets to @_substance. With Data.js you can: Model your domain data using a simple graph-based object model that can be serialized to JSON. Traverse your graph, including relationships using a simple API. Manipulate and query data on the client (browser) or on the server (Node.js) by using exactly the same API. 

Mucho por decir no hay.... "Adobe also suggested that Web application developers in the future would be using HTML5 rather than Flash."

Otro approach mas generador de oportunidades para la empresa podría haber sido sumar al SDK un compilador que produzca html5 en lugar de flash. Y sin duda mucho mejor recibido por todos sus clientes actuales y por todos los que vienen invirtiendo en flex!
