Virtualization and HA, Scalability
-
@dustinb3403 thats the question problems faced by organisations implementing highly available and scalable computing resources, evaluation of potential solutions, selection of a solution for the organisation chosen and discussion and critical evaluation of implementations with particular reference to the lab systems installed.
-
The number one problem that companies face is that these topics are widely misunderstood, to the point that almost no organization is able to identify properly when then need high availability and most can't identify if they have it already. If you look at many tech communities, especially buyer focused communities, you'll find people deploying things that not only are not HA at all, but are actively undermining HA, and being convinced that they just got something very different than they did.

@scottalanmiller thanks

Unfortunately, there is so much money to be made in faking high availability that it has become a common place for businesses to run very broad scams that have gone on for so long and that no one will talk about that no one is willing to admit that it is happening because everyone knows a LOT of people that would be highly embarrassed if anyone found out that it was all a scam and that they should have seen it coming.

Is there a question or are you attempting to define virtualization?
Sounds like a hell of a homework assignment.

Pretty much.

@rojoloco its one of the question on the assignment but i was struggling with just this one

Yeah, the scope is huge.

We are struggling with it, too

The big answer, in the virtualization space today, is hyperconvergence. It is the only architecture for virtualization that is designed to address this issue rather than to address a different issue and then has to be adjusted to handle HA.
Nearly all HA deployments done today should be hyperconverged, rather than anything else.

@scottalanmiller at least you are trying to help people in my group help each other but not me

Well they are your competition, I suppose
When teachers grade on a curve, it pits students against each other rather than encouraging learning.

Technically scalability and HA are completely different concepts. But in modern system design, they come and go together, making the answer often pretty easy. Old style scalability was at odds with HA (the inverted pyramid of doom model) so finding a way to do both was challenging (read: expensive.) But with hyperconvergence, the two are essentially merged and it isn't hard to find them almost always together today. So products that solve one, almost always solve the other.

@scottalanmiller thanks for helping

Any time. We are always here and try very hard to be supportive and welcoming. We have mostly all been through the IT university process and we know how tough it is.
Glad to have you here joining us. -
Some vendors in hyperconvergence to keep an eye on would include @StarWind_Software / @KOOLER and @scale Computing, as well as HPE's Simplivity ( poking @HPEStorageGuy ) as they are leading products and companies and are all active here should you want to talk to any directly. There are lots of players getting into this market, like VMware, Dell, Nutanix, etc. and loads of confusing products. But those three are early leaders with a lot of knowledge and support.

Highly Available systems that are hyperconverged systems typically make the most sense... as Scott said, they also have the benefit of being very scalable. You can easily add more compute, storage, or other resources as needed, by adding more nodes or components to existing nodes.

@tim_g thanks

@scottalanmiller thanks for the mention. As was mentioned, Scale Computing makes scalable, highly available hyperconverged virtualization platform solutions. If there are any questions that we can answer about our products or HC concepts, we're here to assist. Sounds like a good class project and a chance to provide a lot of material for your class.
Is this written work or do you get to give a presentation?

@scale this is written work but we have done a presentation to
