InfoQ: Containers in 2019: They're Calling it a [Hypervisor] Comeback

https://www.infoq.com/articles/containers-hypervisors-2019/

• Near the close of 2018, Amazon amped up an already-increasing interest level in the marrying of container and hypervisor technology by announcing Firecracker, a Rust-based Virtual Machine Monitor
• Around the midpoint of this year, Weaveworks introduced a new project, Ignite, which wraps Amazon’s Firecracker project with a container-lifecycle UI experience.
• One clear use case for this new marriage of hypervisor technology and containers is to add a layer of protection and isolation to potentially sensitive (or untrusted) workloads.
• User experience is also important within the hypervisor/container space: a growing number of companies, developers, and open source projects have become dependent on the simple life-cycle and user experience that Docker brought to the container world. 
• Providing “isolation flexibility” within container orchestration frameworks like Kubernetes is becoming increasingly important. Can and will we have a world where clusters can provide dynamic choice based on workload type? The answer is yes!
