In this chapter, we have covered Docker deployment on public clouds Microsoft Azure and AWS. Both cloud providers provide a competitive container service for customers. This chapter helps to explain the detailed architecture of the AWS EC2 and Microsoft Azure Container Service architecture. It has also covered installation and troubleshooting for all the deployment steps of the container cluster. This chapter has covered the blue-green deployment scenario and how it can be supported in AWS EC2, which is mostly necessary in the case of modern SaaS applications. Finally, we have covered Docker Beta, for AWS and Azure, which was launched recently and provides easy migration of containers from a development environment to a production environment as they are same. Container-based applications can be easily deployed and scaled with Docker Beta, as this service is very well coupled with the IaaS of the cloud providers.
