Future-proofing Your Apps: Cloud Foundry and Node.js

by June 27, 2012

Most real-world applications we ship to consumers or enterprises are multi-year projects. In the cloud era, newer technologies (programming languages, runtimes, frameworks) are created faster than ever. While most of them fail to get any traction, once in a while a technology becomes popular because it solves a problem or set of problems extremely well.
Now in such an era, if you make a large investment for a multi-year project on a PaaS that only supports one technology and some other technology comes along that happens to solve your problem better, then you are stuck. You have unintentionally become a victim of vendor lock-in. The heart of your problem is that your PaaS, and hence your app, was not future-proofed to begin with.

Heads Up on Some New Cloud Controller Features

by June 20, 2012

As I discussed in my post at the end of April, the Cloud Controller is undergoing major surgery and this work is being done in the cloud_controller_ng repo. If you are following the review stream for the cloud_controller_ng project, its time to take note of the new Organization and AppSpace objects. These objects are the foundation of several new features we are rolling out this year:

operational collaboration
advanced quota management and control
custom domains and assorted application features

This post will focus on the objects themselves and will discuss operational collaboration to demonstrate their significance. Other features will be discussed in subsequent posts.

Deploying Tomcat 7 Using the Standalone Framework

by June 18, 2012

The new standalone framework support greatly increases the number of different types of non-Web applications that can run on Cloud Foundry, including application servers. This tutorial will walk you through the steps to deploy a “hello world” application in a Tomcat 7 container on Cloud Foundry. Currently, Cloud Foundry leverages Tomcat 6 to host Java web applications. While the team is working to support Tomcat 7 as a first-class container, it is very straightforward to use the standalone application support to run Tomcat 7 in the meantime, which is particularly useful for applications that leverage Servlet 3.0.

Administer Cloud Foundry with Mobile Apps

by June 14, 2012

One of the neat things about Cloud Foundry is that, because the code is open source, it’s easy to see how the administration tools (such as the command line-based vmc) work. The Cloud Controller component has a REST API, which provides the ability to query and modify the Cloud Foundry environment. That means it is relatively straightforward to build a management user interface tailored to the platform you are using, or to the requirements and needs of a specific set of users.
To illustrate this, I made a really brief video which I tend to use when I’m speaking about the Cloud Foundry platform and ecosystem.

Open Web Foundation Agreement for Activity Streams Signed

by June 13, 2012

At Cloud Foundry we care about making life easier for web developers and API developers. Open source helps developers reuse code. Open standards help developers reuse protocols and schemas. We are pleased to announce that VMware has furthered its commitment to open standards with a signed agreement on Activity Streams specifications. VMware signed the Open Web Foundation Agreement (OWFa) for the JSON and Atom Activity Streams specifications, which gives application developers confidence in implementing these open specifications when building web applications and services.
What is OWFa?
In short, the Open Web Foundation Agreement is a promise made by the signing company that they will not assert IP Claims over the work covered in the specification.

OWFa 1.

Redis in Action with Cloud Foundry

by June 12, 2012

Redis is a popular open source, advanced key-value store project sponsored by VMware. It has been a Cloud Foundry core service from day one and is widely adopted by developers who love its performance and flexibility. In the following guest post we introduce Dr. Josiah L. Carlson who discusses his upcoming book Redis in Action and  describes how Redis is continuing to change the lives of developers.
Guest blog by Dr. Josiah L. Carlson, a well-known contributor on the Redis mailing list
Over the last several years, a wide variety of non-relational databases have been created to offer varying balances of performance, reliability, and non-relational data models.

Cloudfuji Accelerates Delivery of Its Open Source Application Store with Cloud Foundry

by June 7, 2012

Unlike most Platform as a Service offerings today, the open and extensible nature of Cloud Foundry means developers will not be locked into a single cloud or remain beholden to the feature set delivered based on a vendor’s timeline. This month, in our series of guest blogs by application developers, we are featuring the story of Cloudfuji, a modern business application store that uses Cloud Foundry to keep itself nimble and focused on getting to market quickly.

Guest blog by Sean Grove, co-founder of Cloudfuji:
We built Cloudfuji, our modern business application store, on the principle that amazing apps should be 1) easy to make, 2) easy to find, and 3) seamlessly work together.
