To 2): if the container is provided by a 3rd Party, i.e. neither by the OS nor by the MS owners, a clean architectural solution (considering the SO spirit) would be that the the container provider take care of the container updats caused by the OS updates - this is the work of the "copyer", not the the "origine" owner. Why so? Because OS is not a service - it is a part of the environment where the service provider - the container owner - operates and provides its 'container' service to the MS-consumer. Today, I've heard about "container orchestration". Are we once again placing a card ahead of a horse? Who set the rule 'one MS - one container'? IMO, this is not rational rule becuse requires additional (not resource) maintenence of identity of multiple containers (images) for several MS tha need the same containers. - Michael Sent: Tuesday, March 06, 2018 at 1:54 AM From: "Ken Laskey" <> To: "Mike Poulin" <> Cc: Subject: Re: [soa-rm] Invitation: Oasis/NGINX+ Discussion @ Wed Feb 28, 2018 9am - 9:45am (PST) () 1) VM has a full OS running on the VM. Any supported OS can run on a VM. A container uses the same OS as the host. The major benefit is the image is much smaller because it makes use of the host OS and only packages what is needed besides what the OS provides. It also takes less time to spin up a container. 2) The container is an image running on top of the host OS. It is only what is needed to enable an exact duplicate of a machine running some app. A VM could also be such an image but it is much larger because it has the full OS and takes longer to spin up. I am assuming a consumer of an image subscribes to notifications that the image has been updated. It is a reasonable approach but not necessarily the only one.

Do I have the same understanding as you? 2) what does mean a " copy of my machine" and why the one whose machine/image is copied should care of notifying the copiers; isn't this is duty of the copier to have a correct current copy?

The following are possible points for discussion: - how do I keep a microservices’ data store in synch with other data stores (dedicated to individual microservices or an enterprise data store)? - when an application uses several microservices, are those microservices in the same container (VM?) or separate containers for each? - from previous question, what are the considerations for communicating among the microservices in the same container or across containers? - With microservices, I am concerned that we’ll see benefits in the short term but end up with an unwieldy set of near duplicates when there is no time invested to discover if someone else has already solved your problem, especially when their solution will be better than yours. - To what extent is MS just packaging and reuse is you locally spinning up a copy of my machine image so you get to use my solution while avoiding the remote networking overhead? The challenge is for me to notify you when I change/update my image and then you staying in synch with me to the extent that updating is necessary and provides you value. I have a meeting offsite until 11:30 ET but I should be back in my office by noon. My apologies if I am late but I expect others in the OASIS TC can keep you occupied :). Looking forward to the discussion.
