Product@SpotInst here. Just fyi, we have customers launch Spark workloads that require 300G RAM and we are able to efficiently deliver this capacity by ensuring that the underlying infrastructure is shared with other pods that are not memory bound. We bin-pack, scale up and down quickly, while allowing you to have warmed-up spare capacity when needed to ensure that your pods/tasks are serviceable immediately.

Fwiw, Product@SpotInst here. Might I suggest that you give us a try. We ward off against this specific scenario by calculating a Spot score based on Instance Type/AZ and deliver flexibility with a choice of different instance types.

Fwiw, Product@SpotInst here. Curious what makes you arrive at this conclusion? At SpotInst we have customers who migrate between Spot <--> RI <--> OD everyday.

Fwiw, I lead Product for Ocean at SpotInst. Your analysis is _spot_ on :). At SpotInst, we predict interruptions by calculating a Spot Market Score which is based on Instance Family, Type and AZ (using historic data). This allows us to spread pods/workloads across a variety of spot instance types while delivering an SLA. As an additional data point, we have a mix of stateless/stateful workloads running 24x7 on our platform. For critical/management workloads/apps, RI could make a lot of sense and we can dynamically buy/sell those on your behalf, delivering a fully-managed Spot <--> RI <--> OD solution where needed.

Full Disclosure: I, Manik Taneja, am the Product Manager for all the open source efforts at Docker and work on the Moby Project.

As suggested here, the blog post only talks about installing the Docker Community Edition (CE) that is published under Apache 2.0 License. This is the official incarnation of the Docker Product and is provided to have:

- a consistent user experience across different linux distributions - strong security guarantees - regular bug fixes and updates

Moby Project serves as the upstream for the entire Docker Product and includes all open source components that make up Docker, such as runc, containerd, notary, moby, infrakit, linuxkit, libnetwork, hyperkit, vpnkit, datakit, etc.
