To really take advantage of cloud, software must be optimized to run in the cloud. This presentation explores what it means to be "Cloud Native" and looks at a real open source project that has built a complete Cloud Native platform. Cloud is not just a better way to run existing software, there are core enhancements that need to be made to software to enable it to run really effectively in a cloud environment. Often the first thought is about massive scalability, but actually there are other key enablers: multi-tenancy, metering, dynamic distribution, self-service and incremental deployment and testability. This presentation explores these enablers and looks at how an Open Source project (Carbon) built on Apache technology was re-built to be cloud native. The presentation will cover not just the concepts but dive into the practical issues in making a cloud native system and also explore which Apache technologies can help along the way.
