Designing Portable Applications With Cloud Foundry

by December 13, 2012

In the cloud computing world, preserving a choice of clouds is critical. The risks of being locked into a single cloud are substantial. Cloud Foundry provides an abstraction layer for deploying and scaling applications and preserves the ability to move between clouds today and into the future.
In this guest blog, Mark Geene and Vineet Joshi, Co-Founders of Cloud Elements, a Cloud Foundry Core application developer, provide guidance on how to design cloud portable applications while not compromising performance or functionality.
Why Portability is Important

We often find that the cloud provider clients select when they first develop their application does not meet latency, uptime or redundancy requirements as their application scales.

Preserving Cloud Application Portability – Introducing Cloud Foundry Core

by November 13, 2012

The Cloud Foundry team is happy to announce Cloud Foundry Core  –  a program designed to preserve cloud application portability.
In the cloud computing world, preserving a choice of clouds is critical. The risks of being locked into a single cloud are substantial. Pricing, reliability, geographic location and compliance can all vary between clouds. Business requirements will evolve over time, necessitating the ability to move between clouds, whether public to private, private to public or between public cloud providers.

Cloud Application Portability Made Easy – Introducing Cloud Foundry Core

by November 13, 2012

The Cloud Foundry community is happy to announce Cloud Foundry Core  –  a program designed to make cloud application portability easier than ever. Cloud Foundry Core provides a baseline of common capabilities and an open mechanism to instantly validate application portability. Today we announce five Cloud Foundry Core compatible instances. AppFog, Tier 3, Uhuru Software, Micro Cloud Foundry™ and CloudFoundry.com are now Core compatible as part of their commitment to preserving cloud portability.

New Release of Micro Cloud Foundry

by November 8, 2012

We are excited to announce a new version of Micro Cloud Foundry™ with a new set of features. Among those new features is a new process to streamline frequent updates so that we can maintain compatibility between Micro Cloud Foundry and any Cloud Foundry-based clouds, including CloudFoundry.com.
If you don’t have a Cloud Foundry
account yet, sign up here.
Micro Cloud Foundry is a complete version of the Cloud Foundry open PaaS, but it runs in a single virtual machine on a developer’s computer. Micro Cloud Foundry exemplifies how a multi-cloud approach to PaaS can help developers easily develop and test their applications locally and deploy to any Cloud Foundry-based clouds with no code or configuration changes.

Build a Real Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB 2.0 – Part III

by September 11, 2012

In Part II of this series, we covered the architecture needed for persisting the Activity Streams to MongoDB and fanning it out in real-time to all the clients using Redis PubSub.

Since then, some exciting new Node.js features for Cloud Foundry were launched. In addition, the MongoDB version on Cloud Foundry has been upgraded to 2.0.
In this blog post we will cover how to:

Use Mongoose-Auth to store basic user information, including information from Facebook, Twitter, and Github, and how we made this module with native dependencies work on Cloud Foundry
Use Mongo GridFS and ImageMagick to store user uploaded photos and profile pictures
Perform powerful stream filtering, thanks to new capabilities exposed in MongoDB 2.

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.

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.

How OpenCredo Launched Three New Products in Seven Months with Cloud Foundry

by March 22, 2012

From the beginning, Cloud Foundry has been about simplifying the development, deployment and operation of cloud applications.  In this second post in a series of guest blogs by application developers, we bring the story of OpenCredo and how Cloud Foundry helped to launch three new products for a major insurance company in just seven months instead of what would typically take years.
