In this chapter, we have looked at the implications of developing and deploying applications to a cloud environment. We have considered how containers work, how to deploy containerized applications to a cloud platform, and an alternative model: serverless computing. We also presented the 12-factor model principles for the development of cloud-native applications.

We then looked at Hyperledger Composer as an accelerator for developing blockchain solutions. We explored various features, including using authentication, multiuser mode, and data source configuration.

This book provides information on creating simple applications using IBM Watson IoT Platform and Hyperledger Compose. These are far from being the only platforms and tools that support IoT and blockchain solutions, but the concepts are the same and can be applied. If you are interested in extending capabilities with the explained tools, both Watson IoT and Hyperledger Fabric / Composer,  provide extensive documentation on how to use them as well as a large number of community provided articles through out the internet but, our thought is that practice is the best way to understand whether they fit or not to a given solution so, even if you do want to learn how to use the toolkit, just try, simple use cases are good teachers.
