Containers are ideal to package microservices because, while providing isolation to the microservice, they are very lightweight, and you don't incur a lot of overhead when deploying many microservices as you do with virtual machines. That makes containers ideal for cloud deployment, where allocating a whole virtual machine 
for each microservice would be cost prohibitive.

All major cloud providers, such as Amazon AWS, Google's GCE, Microsoft's Azure and even Alibaba Cloud, provide container-hosting services these days. Google's GKE has always been based on Kubernetes. AWS ECS is based on their own orchestration solution. Microsoft Azure's container service was based on Apache Mesos. Kubernetes can be deployed on all cloud platforms, but it wasn't deeply intergated with other services until today. But at the end of 2017, all cloud providers announced direct support for Kubernetes. Microsofts launched AKS, AWS released EKS, and Alibaba Cloud started working on a Kubernetes controller manager to integrate Kubernetes seamlessly.
