Open-source cloud frameworks: A work in progress – Computerworld
When IT consultancy OpenCredo set out to launch three new applications within seven months for a major insurance underwriter, it had three goals in mind: Trim development time from the usual years-long pace, allow for frequent changes from the client, and build a system that can handle unpredictable traffic spikes.
By using the Cloud Foundry open-source framework along with other open-source software, OpenCredo eliminated "heavy lifting" such as configuring virtual machines and adjusting the size of storage volumes, says CEO Russell Miles. The framework allowed developers to write code locally, share it with the client, and automate the integration, testing, and deployment of application components.
Among other advantages, Cloud Foundry makes it easier to scale an application by adding more instances without downtime, Miles says. Because of the way it works with other open-source software, new features can be added in minutes rather than hours.
