OMG wouldn't that contained jobs thing be saving me like days of work right now, especially if it contained the SSIS packages too!

Just considering the backup piece, I feel like this could lead to problems. Right now we use instance level backup jobs which loop through all the databases sequentially and back them up one at a time. What happens if each database contains its own backup job and they are all scheduled to start at exactly the same time? That could really put a strain on both the disks that hold the mdf files and the location where the backup is being written. I also feel like that would be complicating one of the parts of our jobs that are rather simple now. DBAs know which databases in an instance need which kinds of backups, and can manage them together. If the backups were managed at the database level, we suddenly have 10s, 100s, or even 1000s of individual backup jobs and schedules to maintain.

Once SQL Agent and SSIS are ported to Azure, I expect they will be contained at the database level, functionality which would probably trickle down to the on-prem version of SQL Server as well.

Easily. Microsoft could add logic that allows jobs with the same name to be scheduled sequentially.
Don't forget, this isn't something you manage and maintain constantly. How often do you revisit backup jobs and schedules? How often do you move databases? It's rare.

This is somewhat off-topic and yet its related. Steve, you mentioned a link using the text "a little reading" in your article. On the website simpletalk.com, I believe. Well, as is the case with a great many useful websites, my employer blocks them. So, instead of "a little reading", for me its "no reading at all!!!!!!!!!!"

So would someone please be kind enough to give me a short synopsis as to what that link describes? I'd appreciate it.

Actually both Chrome and Edge are complaining about the security certificate for the SimpleTalk site. Yikes!

Really it's an article that talks a bit about the history of containers and how they differ from VMs. Essentially a container reuses much of the host kernal and base system on Linux. On Windows, it uses most of the core Windows functionality, but provides some separation for applications. This is primarily to allow things like Java 8 and Java 9 to both exist in a single container, where they might not normally be allowed on the same OS host. Many types of applications struggle to have multiple versions of the app running at the same time. Containers allow separation.

I can imagine quite a flexible constraint system based on time, whether the database has (non-system) peers on the instance, signals/events, specifying whether parallelism is allowed or not, etc. These rules should be specified within the contain with values, events and signals passed in to each container to evaluate.

I hope they add linked servers but for each database.
