The Cloud and Cloud Architecture Explained - Computer Stuff They Didn't Teach You #15

Most folks are just using the cloud as "a virtual machine in the cloud." This is an easy but somewhat naïve perspective. Let's talk about persistent cloud storage, the VMs that sit on top of that, and the software that sits in top of that and try to demystify the cloud. We'll use Azure as the example but this is a nondenominational video.

[@alpsavasdev]

[@mrallelectriccarlunacy]

"There's the Azure computer, and then there's a Google computer, and I understand that there's a popular bookstore that has a computer." ROFL :D

[@KenSherman]

Great presentation. I loved how you cautiously explained it. 36:45 What's more is you alerting ⚠️ us of a real time attack or hacking attempt that took place up to the millisecond from some point in time. Not sure why someone would do that, but it was a great experience to see on the dashboard for training/demo purposes.

[@GabrielBeaver]

The Azure doc and the drawing of the lines at the beginning is VERY relatable 😂 The funny part is I’ve been on both sides of this, being in the industry. The cloud is confusing is very true statement. Another excellent video in this series Scott!

[@mytechnotalent]

Very thoughtful and careful approach to your explanation. For a lot of us I think this really helps to better visualize the big picture. Thank you again Scott!

[@travissmith8180]

Hi Scott, I've seen a lot of classes over my career suffixed with things like processor, handler, queue, system, service, repository, invoker, etc. When I first got into development, I really struggled with knowing why people used these suffixes as they seemed really vague. It would be great if you did a video that tackled this.

[@mwonsil]

I wish more people in IT would watch this video. Cloud is a spectrum from Co-loc to Serverless. This is a great explanation of how one can get to "Joy". Thanks Scott!

[@morosis82]

Serverless is awesome. I use it at work for API stuff a lot, and once you get your head around it it's fantastic. That said, it doesn't do everything, and we have lots of applications running in everything from on-prem application servers, to containers, to serverless, and queues, all interacting. Integration is fun.

[@anpascally]

do you know why I love this guy's videos? I know he is master at his job but another thing is that his English is perfect. People like me, whose native language is not English and want to learn these stuff on internet have issues because of speaker/youtuber accent, speaking too fast etc. But this guy tells everything so smootlyh and understandable. I really appreciate of your videos and respect you. Best regards.

I'm one of those who didn't know you can have more than one app on a cloud. Thank you so much for sharing your knowledge. Looking forward to see more from you and wish you well.

[@morosis82]

It depends. What he is talking about here is a sort of abstracted virtual machine where you don't have to worry about the operating system and can deploy virtual appliances (in the form of application servers) that have been predefined. In this case, rather than having a virtual machine that you then need to install say IIS on, then configure it, add your site, perhaps some routing rules if you run more than one site, etc. You instead abstract away the OS and just say I want to run an IIS based website and Azure sets up the virtual machine with the appropriate software stack to do so. It might do that with a container technology, but you don't really care exactly *how* you get a webserver, just that you want one. This is slightly different to I want a website and don't really care where it's run, and then the service provider can move that application container where they want as long as it meets the service goals.

[@MikevanKuik]

Thank you for explaining that so calm and clearly. Would you be willing to do a video on a (small) example project with say: * A website * A storage solution (blob or whatever is appropriate) where the images for that site could be stored * A database (sql / mysql) * A dashboard which will give the insights on usage and costs. Starting from scratch Azure and the like all are very daunting. There are so many options so even for a small project like a blog this can become a mayor undertaking to figure out what to use.

[@dickmcglade]

I never write on youtube comments but felt the need to this time. Watched an intresting random video the other day that I thought might help a college get his head round powerpoint and obs in the end was interesting for me and now this apsolute gem.

[@mau_lopez]

Fantastic video, I have several instances of Azure SQL Database and a couple of VM's. I'm very happy with the service but really know very little about everything else Azure (and others) have to offer, so today I had a glimpse of what else is up there in the cloud explained in a very clear and enjoyable way. I didn't know that some dashboards, telemetry and costs can be so detailed. Thanks a lot Mr. Hanselman.

Hey Scott. Loving your work as always Mr. A suggestion for future episodes. Perhaps you could consider including someone that would be asking the questions around the topic?

Love the way you teach..love the part after 19:00 example

[@HugRunner]

Great video Scott! The no BS-approach is much appreciated! I think that what intimidates me from using a cloud service like Azure, is that it's so much harder to get a grasp on what the final price is before I have subscribed and tested things out already. Right now I'm using a traditional web hotel, where I get 200 GB space, unlimited domains, MS SQL and MySQL-databases, and I can mix Linux and Windows on the same package, and all this for about $20/month. The problem though is that the provider lags behind on support for newer version of .NET. It doesn't even have Core support yet. But, at least I know what I get and how much it costs. I know there are calculators to approximate the cost for cloud services, but I still don't feel confident to give it a try, especially when the calculation often seems to add a lot of cost for adding additional storage space. I have 3-5 .NET projects and around 15 Linux/Apache-sites, none of which is super demanding. Do you have any advice for someone in this situation? What services should I look at in Azure to get something similar to what I have but with support for new tech, without the cost going through the roof? Could you perhaps do a video or blog touching on storage, e.g. if you need a file server for your app?

[@shanselman]

$20 is pretty amazing. I don’t think Azure can ever beat that

[@HugRunner]

@@shanselman Yes, I do understand that it's not possible for Azure to compete with the normal or budget web hotels out there in terms of price, but let's say I were to set up 5 .NET Core/5 projects on Azure, with 5 MS SQL-databases and domains. Would one App Service in Windows-environment (or should it be Linux?) suffice? You didn't talk much about IIS (or Kestrel) in this video, I assume all of that would be taken care of so that a .NET Core App would run the same on either OS/environment?

[@marcpanther7924]

Scott, can you convince the Win10 team to allow easy creation of ramdisks like in Linux? (no 3rd party apps)

[@mrallelectriccarlunacy]

My VS solution that writes several GB of binaries would love that. Trying to use 3rd party ones makes me wish it was a supported feature in Windows, even if it was limited to Pro and Enterprise or sold in the store for an additional fee.

[@daraoladapo]

Enjoyed the part where MS folks pull out that Azure services diagram and get people more confused rather than explain from the basics and fit into user scenario. I enjoy explaining Azure using scenarios and fit into the needs of the person I'm explaining to.

[@bluesdog88]

Thanks Scott for breaking it down into byte sized chunks, excellent presentation! I'm still a little confused by the web apps a little, are they talking about websites, or applications like Office. I'm not sure how i got this line of thinking, might be confused with deploying desktops over a LAN and thinking that is the same thing. So when they dockerise an application does that mean you can containerize your adobe apps when someone says web apps i immediately think facebook or something

[@morosis82]

Not sure which web apps you're talking about, but in terms of Scott's website essentially what he's talking about is an abstracted IIS, for example. How it is deployed is irrelevant, just that you have a website hosting platform that you can put a site on and configure to do certain things, and Azure deploys that how they see fit on the abstracted virtual machine that you also don't see. Office 365 is a webapp, Facebook is a webapp, a virtual desktop isn't really, it's more like a managed service, or Infrastructure as a Service - you can run whatever apps you like on a windows desktop environment, but the OS itself is abstracted and patches etc managed by Azure, for example. Think more like the old mainframe/thin client infrastructure, except delivered virtually over the network to any client you may have available at the time. Containers are generally more for non-gui type apps - you can containerise user applications, but generally you would containerise something like a game server, or a piece of support software like a database server that a user app might talk to. We use this in development all the time, so we can spin up mock supporting services for the piece of software we are currently working on. Containerisation is just a nice way of saying bundling the software with all the dependencies it needs to run, and sandboxing it so it can't talk to anything it's not allowed to (you can open ports and things, but generally it's sandboxed). You still need to define the setup within that container, what you need and how it gets installed. It can't see anything outside the container, unless you explicitly map part of your filesystem into it, or a shared network filesystem, for example. In your example, the adobe container would need to have your project mapped into it on some sort of filestore, it can't generally access your local filesystem. What that allows you to do is run this piece of software anywhere you like, on any container infrastructure, on a dev machine, or a cloud server, or under a kubernetes that might decide it needs 10 of them for the load. That container does just one thing, it's the infrastructure around it that ties things together to fulfil a purpose. Serverless goes one step further - you don't care how or where a piece of code runs, only that it does. It might be in a container (probably is), but it's not on a specific vm or anything, the service provider decides how they manage that. You just have an API exposed to the web, and a piece of code that does something when it's called, and perhaps some configuration to allow it to talk to the hosted database server you also spun up that you don't care how or where it runs, just that it does. The database server is more like an application as a service, you don't have access to the VM it's running on, just access to a database. My experience is with AWS (and proxmox) so terms might be slightly different but does basically the same thing.

[@bluesdog88]

@@morosis82 WOW Matthew, thanks so much for the detailed explanation, i kind of got that a virtual desktop deployed over a network wasn't the same as a cloud solution, when you talk about facebook as an app are you talking about the phone app? If so then that's easy! I guess i haven't had much exposure to command line tools like databases etc, anyway thanks, gives me a lot of food for thought to get this stuff down, cheers!

[@morosis82]

@@bluesdog88 NO worries, have been on a bit of a journey recently myself, gone from full java backend monolithic system programmer to AWS cloud serverless in the last year or so. Virtual desktops can live in the cloud too, not just a local network, Amazon Workspaces is one example. Haven't used it, but looking at setting something up on my homelab to do something similar when I'm away from work/home. Facebook is a web application in that you don't store anything locally, all of your interactions are via a browser (or a phone app, but honestly mostly that's just a thin veneer over a web component). They're different from a traditional web page in that they are dynamic and you don't really go from page to page but open dialogs and transition states - react is the language used for their UI, and I've been using that at work also. And databases aren't command line tools anymore. Things like RDS and DynamoDB in AWS are cloud based DB's where you don't even need to know the host, the system, just the schema you want to load and how to poke at it. Takes about 10 mins to set up and get some lambda's behind an api gateway poking at it if you want to prototype things, all through a fairly convenient web form configuration (assuming you're down with that lingo, might take longer if you have to learn what lambda, api gw and dynamo are ;)
