The Twelve-Factor App - 2 views

shared by munyeco on 20 Jul 14 - No Cached
  • 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).

    "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.

How the DevOps revolution informs software architecture - O'Reilly Radar - 0 views

  •  
    "Ford noted the growing relationship between software architecture and DevOps. The interdependence of the two disciplines is evident within Ford's company: "One of the things that we're really adamant about now," he said, "is that someone from DevOps and operations should be a full-time member of a software development team … you cut way down on churn and other sorts of useless engineering activities.""

Microservices and PaaS - Part I | ActiveState - 0 views

  • Instead of building software that resembles our existing organizations, we should figure out how we want our software to look, then build the organization around that. Or reorganize it if it's already in place.

      Las implicancias de esta idea en nuestra organización...
  • When deploying a new feature, enhancing or fixing an existing capability, or deploying an experimental line of code, the previous code remains available and accessible. New code is deployed alongside the old code, with mechanisms in place to instantly route to one or another version.
  • Importantly, the old code is not replaced, but remains part of the system, and is kept running. If, as is often the case, the widespread introduction of the new feature results in unforeseen consequences, the feature flag can be toggled off, and the old version is instantly used instead.

  • In a microservices architecture, an application is comprised of a number of small, independent composable services that interact by way of an external published protocol, such as REST, or a messaging service.
  • Each service is focused on an individual targeted business capability, and thus its scope is minimized. For functionality out of scope, the microservice calls out to other microservices via the published protocol.
  • Small independent microservices can be built using the technology best suited for their requirements. No longer does every application component need to be built on a common company-mandated language and framework such as Java/Spring or Ruby on Rails.
  • Similarly, there's no reason to standardize on a single persistence layer across an entire application. Some microservices might best be served by Redis, others by Oracle.
  • Each microservice can be updated independently, no longer requiring the entire application to be redeployed.
  • Microservices drastically improve the time required to push out a new update, allowing a much more agile development process.
  • Many organizations consist of specialized silo teams (UI, database, API, etc) where costly handoffs and intercommunication are required to coordinate all the pieces of application construction. These handoffs cause overhead, and the need for them should be eliminated.
  • With small teams, each focused on an individual microservice, Netflix enables developers to push code to production, instead of getting mired in a complex deployment process involving several teams.
  • With microservices, the old IT mindset just doesn't work.
  • A centralized IT department cannot possibly cover the wide array of technologies spanning all microservices.
  • Instead a DevOps structure, where each team is responsible for the management of the corresponding microservice, is essential.
  • Enable developers to concoct systems of their choosing with minimal or no interaction from IT, management, VPs, hardware or other groups. "Self Service" is one of the major capabilities offered by the cloud and there's every reason to take advantage of this.
  • Now, IT can be considered as a cloud API available to the developer on-demand 24x7, instead of a complex, process-mired division hidden behind obscure process.

Docker Acquires SDN Technology Startup SocketPlane.io - The New Stack - 1 views

  •  
    "In an indication of how rapidly the containerized technology ecosystem is metastasizing, SocketPlane.io - a startup venture founded just last October with the goal of building a controller-less software-defined network model for Docker environments - is being acquired by Docker, Inc., the two organizations jointly announced Wednesday morning. SocketPlane creates a networking abstraction for Docker containers at the socket layer. It connects containers without the need for a network controller, either physical or virtual. Put another way, it facilitates a software-defined network by letting the containers be the network."

All about Apache Aurora | Twitter Blogs - 1 views

  •  
    "What is Aurora? Platforms like Twitter operate across tens of thousands of machines, with hundreds of engineers deploying software daily. In this type of environment, automation is critical. Aurora is software that keeps services running in the face of many types of failure, and provides engineers a convenient, automated way to create and update these services. To accomplish this, Aurora leverages the Apache Mesos cluster manager, which provides information about the state of the cluster. Aurora uses that knowledge to make scheduling decisions. For example, when a machine experiences failure Aurora automatically reschedules those previously-running services onto a healthy machine in order to keep them running."
