Platform Wind Tunnel, Part I: Heroku


For well over 100 years, engineers have utilized wind tunnels to study the effects of aerodynamic forces on airplanes, buildings, automobiles, and other structures. This testing is conducted as part of a full suite of analyses intended to demonstrate, among other things, the ability of these structures to withstand various forms of stress.

Optimizing Bosh-Lite Deployment Times

featured-polycloud-green This post continues our CI pipeline series. In this edition, we talk about how we optimized the pipeline’s Cloud Foundry deployment step (into bosh-lite on AWS) from previously over one hour to about 20 minutes, resulting in shorter feedback cycles and therefore faster development.

Using Docker For CI Pipelines

featured-dcloud A previous post explained CI pipelines for loggregator, and this post zooms in on why the Cloud Foundry engineering team uses Docker and how. A background is given and covers the problems faced without Docker and the benefits. Then, one of our top engineers, Johannes Petzold, explains how we use it and the issues we've seen.

Docker Service Broker for Cloud Foundry

featured-clouds-whale Pivotal's Cloud Foundry team is a fan of Docker. In this post, learn how the Docker service broker for Cloud Foundry allows users to expose and provision services offerings that run inside a Docker container and bind applications to those services. One of Pivotal's expert Docker and Cloud Foundry engineers covers everything from the broker use cases for multi-database engine tests, log draining, known limitations, and information to get started using Docker and Cloud Foundry.

Session Replication on Cloud Foundry

featured-polycloud-green Recently, the Java Buildpack added support for session replication using Redis. This support complements the existing session affinity (i.e. sticky sessions) that Cloud Foundry already supports. So now, in addition to having sessions routed to the instance they were created on, sessions will also survive the loss of that instance. The Java Buildpack will auto-configure Redis-based Session Replication for you when it notices that you’ve bound to a specially identified Redis service. This post describes how this works.

Experience NO LIMITS: Join Pivotal at VMware VMworld US 2014

featured-vmworld-NoLimits This weekend Pivotal will join forces with VMware and our collective customers at VMworld 2014. Pivotal will lead six sessions covering various uses and areas of Cloud Foundry and Pivotal CF. Attendees will also be the first to get a preview of the new Pivotal CF Mobile Services which will accelerate how companies can develop mobile applications, by offering critical services for things like push notifications, API gateways and data sync that are built into the platform. Additionally, you can find Pivotal experts demoing Pivotal products such as the Pivotal Big Data Suite and Pivotal CF in booth #941, located towards the center by the VMware booths.

An Overview of Loggregator CI Pipelines

featured-CF-logo-partA Cloud Foundry at Pivotal recently set up new continuous integration pipelines for loggregator, using Thoughtworks’ Go (not to be confused with Go, the programming language.) This is the first in a planned series of related blog posts; its intention is to provide an initial overview of our pipelines.

How To Win In Mobile App Development, Quickly

featured-PCF-mobile With over a billion smartphones, which 90% of people keep within arm’s reach at all times, businesses must shift their development priorities to “mobile first”. There is a popular concept that today every company is becoming a software business. The reality now is that every company must become a MOBILE software business. To support that endeavor, Pivotal looked to the technology and expertise of the Xtreme Labs team (acquired in 2013), who have developed over 400 mobile apps, with 400 million downloads, helping to bake their mobile development best practices into our vision for the third platform. Today, we announce the next step in that journey: Pivotal CF Mobile Services.
