This will be what takes containers into the mainstream businesses. Companies may adopt docker or other instead of this, but Microsoft creating their own version of it means its a viable technology. Im more interested in the new frameworks and technologies that get adopted because of this than the fact that its in use. Traditional Java web projects that are hosted on Tomcat/JBoss don't run well inside containers but there are technologies like Node.js that lend themselves to containerization. Open source .NET is now a viable option for linux deployments, and Microsoft's new containers. It will be an interesting couple of years as this shakes out.
- lgas 11y agoCan you elaborate on, or point me to some reading on the issues with containerizing tomcat and/or jboss? This is not something I've encountered before and may become an issue for me soon. Thanks.
- tokenizerrr 11y agoIn my experience the Tomcat/JBoss tend to be a relatively large overhead, but since they can run multiple "war" files under the same overhead this is not as much a problem when running a single container for multiple applications. But when you containerize them you'd like to run one instance per application which will multiply the already significant overhead. Not sure if this is what the GP was referring to, but just my 2 cents.
- jsprogrammer 11y agoMicrosoft creating their own version means the technology is viable? I think people have been using 'the technology' for years, without any input from Microsoft. It doesn't need to be anointed by Microsoft to be 'viable'.
- kirinan 11y agoFor the tech enthusiast and the visionaries, you are correct; It is a very viable technology. However the majority of people that deploy software are rather conservative and unless they see a market leader such as Microsoft with a solution they don't deem the technology safe to use. This is well documented in a lot of literature like Crossing the Chasm but can be observed frequently if you work at a larger non-tech oriented company. Whether or not this notion is actually correct is debatable but it doesn't change the validity of it.
- at-fates-hands 11y agoThis also means a lot of Microsoft shops who have a lot of Docker enthusiasts will be able to pitch this to thier bosses, who might not have been on board prior to this since it wasn't an enterprise MS product. This will open a TON of doors for everybody.
- rbanffy 11y agoI think that when a "market leader" finally adopts technologies that were in use for more than a decade by their competition, it's safe to assume the tech got mainstream...
- protomyth 11y ago> It doesn't need to be anointed by Microsoft to be 'viable' Well, in a lot of corporations its viable when the big analyst companies say its viable (Gartner and Forrester Research) and they tend to be "nudged" by Microsoft. It once was does IBM have an offering in this space and then it became does Microsoft. // one more soul crushing things done in corporate IT
- bydo 11y agoBSD had jails for well over a decade before Linux containerization took off; Microsoft entering the space could very well be good for all participants. A rising tide, etc.
- rsync 11y agoTo be fair, there were things like usermode linux (UML) that were (roughly) contemporary to jail, circa late 2001 / early 2002.
- imh 11y agoAssume a generous reading of the comment, like, "It must be good if Microsoft is jumping on the bandwagon."
- frostmatthew 11y ago> Microsoft creating their own version means the technology is viable? Keep in mind nearly all technologies are used mostly at non-tech companies (e.g. far more software is written by developers not working for a software company) and the software/IT teams at these companies usually prefer solutions from the large/major tech names they know/trust. Microsoft having their own version of something means a lot more businesses will consider using it.
- kbenson 11y agoIt doesn't mean it wasn't viable before, it's just another piece of evidence, which many more people will be exposed to, that it is viable.
- Confusion 11y agoMicrosoft creating their own version means it will be perceived as viable by many more people.
- dordoka 11y agoCould you please explain what kind of issues did you find running tomcat/jboss inside containers? We've been running several apps on docker and so far no problem. Thanks a lot in advance.
- spullara 11y agoEssentially, Java is already run like containers, that container being an application server of some sort. Very rarely is Java software really dependent on specific packages being installed or even which operation system aside from a particular Java VM. When you add another container layer you generally are just adding more overhead and further you have issues with correctly setting some tunable parameters like heap sizes vs container memory sizes, etc. It works, it just isn't very ideal.
- dordoka 11y agoThanks for your reply spullara. We might be one of those rare cases where we do need different packages and libraries for each applications. It's the pain that we have to suffer having to maintain several "legacy" apps. Regarding your view on an app server being a container of some sort, I do agree. We are actually starting to develop apps to be run using embeded app servers (with Spring Boot), as it fits better when running apps using docker.
- spullara 11y agoMakes sense. I've been recommending Dropwizard for years for similar reasons.
- kirinan 11y agoTomcat/Jboss are resource hogs and tend to not do well in sandboxed environments as it takes away a lot of the configurability/tuning that they provide/need for scaling. In addition, people tend to deploy multiple applications per application server to keep resources requirements down: containizeration tends not to lend itself to multi-application stategies (in particular resource heavy applications like those that run on the JVM). This is far from something that makes java an impossibility but it changes the techniques enterprises are accustomed to. Technologies like Jetty provide a good solution to the problem, and will probably see wider adoption as containers become more prevalent.
- pweissbrod 11y agoAt first I was like :D Then I was like :( App containers are SORELY needed in microsoft ecosystem. But whats up with the HyperV vendor lock-in? Looks like to those of us already investing in vmware or EC2 etc get the shaft...
- johngossman 11y agoWindows Server Containers will absolutely work in other hypervisors. You need to be running Windows as a guest OS obviously.
- eldavido 11y agoHi John Former-MS guy here working in SV. I could tell you work at MS by some of the terms you use which aren't common outside the company (e.g. "SKU") but MS people say a lot ;) You should set up your profile on HN so that people know you're an MS guy and write a bit about yourself. I would email you directly, but your profile is blank.

- cbd1984 11y agoIt's been a viable technology ever since IBM started doing it in the 1960s, with VM. Oh, wait. This isn't VM. This is something less-featureful than VM which will, possibly, eventually evolve into VM after a lot of hair-pulling. My mistake.
