I wonder if that is really true or: 1) The reseller doesn't know how it runs over Azure (I had this with vendors sticking to in-house Sharepoint vs Sharepoint online mostly from a "we don't know how" angle we found out) or 2) Does the reseller also make money from in-house vs on Azure? Like, their hardware? Anything like that? Just curious. I mean, he could also honestly think that Azure isn't there yet either. I cou…

Sometimes with heavily DB bound apps, it's a performance/scalability issue. Doubly so if the app's DB relies on aggressive locking for most/all of its transactions. You can do it with clouds but you often pay through the nose for the adequate storage (or cheat with 512GB of RAM these days.) I've seen folks spend 3-4x more money (almost all of the excess to the SAN vendor) to get a VMware setup (because snapshots and…

So much this.

We always said to use "the right tool for the right job", isn't it? There are a lot of apps for which virtualized infrastructure is just not a good fit from a technical standpoint. When these end up in the cloud because suits decided OpEx is sweeter than CapEx, they suffer horribly; the customer ends up paying more (because prolonged I/O spikes in the cloud can be hugely expensive), the application runs slower than it did 5 years ago on commodity hardware, and nobody is happy.

Still, suits decided cloud it must be, so cloud it will be. Sometimes the IT sector is depressing.

ILPIP look promising. I'll try it, thanks! Speed test though... hm... 22Mbit/s is not exactly unrestricted, plus not sure how long is the burst that "speedtest-cli" makes. In my experience A0's uplink is burstable (but unusably slow when recovering from a burst), with long-term average being bang-on 5Mbps. I do of course see exactly one "my" private IP in traceroute, but I'm not talking about that. I meant there are…

Yeah, the ICMP stuff could be a bit annoying :)

My comment about the traceroute was because you previously said that you've found those weird IP addresses between the VM and Internet. That's not how I actually see it, but I get your point, too.

The ones you identify as packet loss are just the ones you didn't get an ICMP back. I don't know anything about your background, but as per my experience with networking I've stopped considering traceroute as something remotely useful further than the first hop long ago, especially on environments outside my control (i.e. Internet). There are things out there like ICMP throttling and the fact that I could send you the "TTL Expired" ICMP identifying myself with any IP address. Remember the "Star Wars traceroute"? http://www.theregister.co.uk/2013/02/15/star_wars_traceroute... (doesn't seem to work for me now).

You're missing something very significant: Compilation jobs involve a lot of forking. Forking, memory accesses, and TLB differences across various VM architectures can have an enormous impact on performance. For example, we found two orders of magnitude performance difference between PV and HVM on ec2 on fork-heavy CI jobs. A difference between 3 and 30 minutes. This difference is trivially reproducible by measuring…

that wasn't always the case. i remember times where pv could be faster on a lot of forks. however you can't compare pv/hvm vs kvm vs hyperv since the difference between pv and hvm is caused by a totally other aspect than the comparsion between hvm, kvm and hyperv. also note hyperv got way better in windows server 2012. also note that fork() involvs "lots of" io computations which could also be a driver problem and th…

>that wasn't always the case. i remember times where pv could be faster on a lot of forks

32bit, or 64bit pre-virtualization hardware extension (vt-x/d, ept, amd equivalents) are really the only ways this should have been the case. Each time you make a fork() system call on 64bit PV you're making an extra context switch and flushing the TLB that an HVM instance does not need

I'm not fooling myself into seeing this as anything but a "you scratch my back, I'll scratch yours" setup. RedHat is getting a ton out of this, and so is Microsoft. Who's the main target for Azure? Enterprise companies who trust Microsoft implicitly. When an exec comes to the head of IT and says "we need to be on the cloud! I read about it!", Azure eases the transition by being able to go to vendor you've already bee…

It's not a trust thing. Microsoft is wheeling and dealing with Azure. So you won't get a deal on O365 or Dynamics anymore, but you can buy Azure credits at a discount. They are using Azure as a loss leader to get you hooked, then the price goes up. This new SaaS world is kind of like buying cars.

Given the pricing compared to AWS and others, I don't think they're losing money on it... It was my first choice when I stopped self-hosting a windows server for some personal projects/sites. Though I'm on about the smallest option, and that is running me around $10-12 a month, I'm using CloudFlare in front of the 5 websites on that box.

That said, nothing big, and planning to migrate things to linux solutions but time and motivation don't always align for personal stuff at the end of the work day.

They seem to be one of the better options if you need hosted windows anything as part of your cloud strategy. And having played around with Azure's other services [1], it seems to work pretty well all around. I did find the default interfaces for Azure's storage a bit difficult to work with, so I created a wrapper with imho a nicer interface.

Why is weird? you do spect that Spring MVC gives you a full Restful experience?, it can give you a good REST experience, but is not for that, the same case with ASP.NET MVC is not spected to give a premier example is RESTFul services that is why Web API exists, and as someone who has used both, Java and .NET, I can tell you that Web API is simpler and as powerfull.

It's weird because there is no good reason to force you to use a different routing system in order to use REST routing. It's especially surprising considering how Rails-inspired it is otherwise.

Obviously you are misinformed, becuase ASP.NET MVC and Web API share the same Route Handler, heck, even I could make my own framework and use the same Route Handler, because it is a decoupled module, so, I invite you to learn more about the topic before making such ignorant statements.

Azure has been mostly Linux Applications for a while now. Whenever Enterprise wants a contract they almost exclusively think Red Hat. So this makes sense for both of them to team up.I also don't see any fallout in the community because of this. Since Ubuntu ruling the cloud instances this also makes sense for Red Hat.

Ubuntu rules cloud instances elsewhere? I almost always see the choices as CentOS or RedHat. But that might be my myopic view cause I am always just looking for those right off the bat.

It depends on what you are going to use it for.

Ubuntu has gotten some solid traction in the "web" end of things, while RH is more "infrastructure".

In the last 5 years we've experimented with Linux on top of hyper-v a few times. The basic I/O, compile & runtime performance was significantly inferior to xen & kvm (didn't bench against vmware, phasing it out due to cost), it wasn't worth any effort to even deploy apps for testing. Therefore I don't see Linux on hyper-v being a compelling option for the cost conscientious technical officer or lead engineer.

Main problem with Hyper-V: getting into the admin console with anything but IE. Yes, really.

Vmconnect(1) is a local exe. The best experience for a console to your Hyper-V VM is remote desktop, but that requires a Windows guest and virtual networking. If you are trouble shooting networking or boot, or are using Linux guests, vmconnect is very easy to use (no network required) and works great.

I'm not sure of any way to get a console through IE. Can you explain?

Actually, in public Internet traceroutes are reasonably reliable. It's corporate networks where you would expect weird stuff like that.

> (About #12, WTF? Weird!)

There is a fairly boring explanation to that. Similar to public IPv4 exhaustion, RFC1918-style private IPv4 addresses can easily be exhausted in a big private network as well. If you have noticed, MS has actually run out of RFC1918, and uses RFC6598 (a.k.a. 100.64.0.0/10) network in Azure for their "classic" segment. 100.64.0.0/10 was not supposed to be used as RFC1918-style general-purpose private IP space, but rather as a local side of a CGN pool. But then again, if you squint a bit, well... it's still private, so will never be advertised into the Internet, so it's fair game to use it if you run out of RFC1918, right?

Some people choose to squint even further, and declare anything that is not advertised into public BGP as a fair game. I've seen a big ISP "borrowing" 44.0.0.0/8 (amateur radio AX.25) subnet to deploy video segment of their huge "triple-play" network. 33/8 (US DoD) is also popular as "borrowed" private space, 1/8 was fairly popular until it actually became real public address space handed to APNIC (oops!). Now we have an example of using 25/8 like that as well.

C# is a decent language if you like imperative programing. .NET MVC, though, is far from impressive. The routing is crap, Razor is designed to encourage you to dump C# straight into your views, and in general it feels like a "let's do Rails in C#", which I really don't see as the future of web development.

As is yours, so why bicker?

C#/.NET is also my favourite, but it's not the be-all and end-all of web development. It might be the best for all of your projects, but not for everyone else.

It has it's flaws, like everything else, and I'm happy for you that you haven't used it (or anything else) for long enough to discover them.
