This chapter was focused on containers in Azure. Azure provides multiple services that are either native or compatible with containers. These services are relatively new features and newer capabilities are being added to them on an on-going basis. Some of the important Azure services related to containers are Azure Container Registry, Azure Container Instances, Azure Kubernetes Service, and Azure App Service. There are other services, such as Azure Service Fabric, which supports hosting containers, and function app containers, which supports running functions in containers. Containers can be hosted either as IaaS or PaaS. Both have their advantages and disadvantages, and organizations should evaluate their requirements and choose an appropriate service for their containers. It is important to know which container service to use in different scenarios, as that would be a key factor for success for an architect in Azure.
