Is Cloud the New Mainframe? (medium.com) 86

Long-time Slashdot reader theodp writes: IBM mainframes were the original onsite private cloud," begins retired software engineer Billy Newport in Is Cloud the New Mainframe? And while there were many things to like about the mainframe (including "crazy high availability numbers which today's cloud vendors can only dream of"), cost was not one of them. "As the application usage grows," Newport explains, "the bill grows and the control of the bill is largely in IBM's hands. You use more, you pay more [...] Unfortunately, while compute is elastic, budgets are not [...] Inevitably, customers try to migrate workloads from the mainframe to 'cheaper' platforms but these projects can be very expensive to do and they do fail more often than people realize."

"Today's Cloud kind of looks exactly the same as the mainframe scenario," Newport warns. "Companies have rushed to get on the cloud with the cool kids. I predict many companies will try to rush to reduce cloud expenditure and will find migrating onsite to be an expensive proposition if it's even possible.

      But we aren't connecting dumb terminals to the cloud (with some exceptions). The cloud is far more analogous to the commodity servers in a company's data centers today than it is to mainframes. Moving away from mainframes was in part because commodity servers gave more flexibility, and the cloud provides even more flexibility than owning your own servers. The cloud is a continuation of the forces which moved us away from mainframes in the first place, not a movement back towards the mainframe.

      There are appropriate use cases for both cloud and data center. There is some overlap but not as much as there is difference.

      Most of my jobs were at places with pretty high 24x7 uses but inevitably some genius new CTO would sell cloud to the board of directors so he could put his stamp on the business and fluff his nest.

      Who was responsible to figure out how to move from data center (often multiple global dc) to cloud? Yup, me.

      First thing was doing a rough cost estimate for building brand new dc opex (3 year) + capex budget for each. For my loads the price difference over 3 years was typically about 8x more expensive to have cloud. Stretch it to 4 or 5 years and it only got worse for cloud because there was lots of dc hardware that was good for 5 years but rental costs never go down.

      Then once in you're cloud it's really easy to lose track of some random cost when you've got thousands of line items going on so nor you have to pay someone for tools to watch and manage your expenses because the Amazon ones suck. It doesn't behoove them to provide effective cost management tools for large scale deployments.

      Then you've got to do daily/weekly/whatever review of your cloud usage to make sure you're not flying off the rails so you're spending more time doing paperwork and budget review than in a data center where costs are static.

      And of course since everything is easy to pop up and shut down, the CTO wants you to give some devs access to spin up their own servers or even fill environments. Naturally they don't shut them down when done or tell you when they're done so during a review you're looking at a huge ass line item and ask dev manager about some environment and the answer is "oh, I'm not sure, you should ask them if they still need it". Which they don't but it's been running for weeks for no reason.

      I've successfully and happily used cloud for long term backup storage, as a DR site, as a secure site for contractors to do work, and as a small well defined site for specific devs teams working on a well watched and managed project. But for 24x7 not very bursty loads, good luck. I wish you well if you moved your entire environment into cloud for non-trivial sized environments.

      Otoh, if I had very bursty traffic or needed it for a one off like Christmas season sales or similar then cloud would be fucking awesome. Spin it up after thanks giving. Turn if off after new years. Winning.

      Obviously, ymmv, but this has been my experience over the years.

              There's a discussion in there. There are some minor advantages but some significant disadvantages that are not immediately obvious. The bottom line is that cost savings make you dependent on the cloud provider in perpetuity, and the expense of making yourself capable of shifting to a new provider when the deal gets worse eat up whatever administrative savings there are.

        • And owning a datacenter is quite expensive.

          • The cost of building and operating a datacenter for a static environment is actually quite reasonable. What gets expensive is when you did it wrong in the first place or your needs change drastically. Many companies got caught with their pants down having grossly underestimating their reliability requirements and had to spend stupid sums of money to address it. Many companies tried to cut costs by skimping on maintenance and process management. Cloud or Co-Lo work for different things, but the CTO or CFO's

          • Most clouds, including AWS and Azure donâ(TM)t have automatic global redundancy. You put your data in a single âregionâ(TM), which often actually means a single datacenter. As many have noticed over the years, even Amazon is not resilient to weather events and software/hardware failures. If you want multi-region redundancy, not only does it cost money, you also have to add transfer fees from region-to-region and that costs money.

          They'll all certainly sell you very classical VMs, just with more room to scale them up or down or bring more online than you probably have at home; but you are starting to look at architectural changes if you wander into the "managed instance" or "serverless" offerings(Cosmos or Aurora DB; AWS Lambada or Azure Functions; S3 buckets; etc.)

        ...the CTO wants you to give some devs access to spin up their own servers or even fill environments. Naturally they don't shut them down when done...

        This is the biggest problem I see with the cloud. It's that unknown cost increase risk. And it applies to all parts of the topic. In addition to what you said, Devs take shortcuts in their coding because they have "unlimited" resources. They stop caring about scaling or cpu cycles. It just needs to pass the testing. They also go JIT on all processing; no more efficient batch processing or dedicating a single CPU to do one task for the next 30 min. Each atomic action is its own process accelerated by the number of resource workers you apply to it. This ends in high overhead at the hardware level that you eventually pay for.

        Management basically encourages this because they want quick turn around and high execution. They get this image by thinking we reduced infrastructure demand turnarounds, without realizing that developers also spent that time thinking about program algorithms and design and collaboration and investment costs and ROI.

        I want to add that availability isn't that great with the cloud. When you go cloud, all the pieces are very high availability. But your devs start making a huge complex web of connections and dependencies. And your end2end product issue now encompasses a complex network of functions, infrastructure, vendors, service desks, and ticket tracking.

        Even for scalability, if your transaction set is in sync with your competitors or suppliers, the cloud does a poor job of seasonal scaling. Everyone wants it at the same time and that region does slow down (ie: retail in the US) at that time. It works wonderfully when you are offset because you are basically time sharing the hardware.

        To me, Mainframes were costly because of being underutilized, and the Cloud is costly because of inefficient over utilization.

        The way I see it, 2+2 always has a minimum cost. And getting closest to that minimum is sometimes on prem backend, smart clients, or cloud depends on the situation. It's always a mix of the various infrastructure.

        I am primarily a cloud architect, but I have very rarely seen examples where lifting and shifting an on-premise suite of applications to the cloud is a good idea. For the most part the only times I see it as beneficial is when a significant re-architecture / re-design is taking place, and the company is taking advantage of cloud services far beyond just having virtual machines in the cloud. The business value has more to do with lower development costs and faster speed to market than long term maintenance costs.

        We basically use our own cloud nowadays. Basically, clusters of redundant proxmox servers running in several datacenters. You pay a fixed price for each hardware server you use and that's it. Much cheaper that way and no vendor lock-in at all.

          We have a local hybrid/cloud provider here where you can rent servers or cloud instances with specific servers. Their support is very good as is the reliability. What is flaky is the ProxMox install image. Always in Beta. Fair enough, ProxMox is so good it would be competition for them.

      What seems to be a major point for our org is that by moving an entire system from shared IT owned infrastructure to the cloud the business now gets to see - and pay full TCO of - whatever it is they're using - no more hidden costs absorbed by IT in the datacentre and other related areas. That gives them much more information about the usefulness of their products and the cost to run and replace them.

If your HQ being disconnected from the Internet means no work getting done, then on site is the way to go. If you want to be able to restore a failed server ASAP rather than waiting for 3rd party support, on site is the way to go.

    His argument that "because it was expensive last time (mainframe utilization reduction) then it will be expensive again this time (cloud utilization reduction) falls on its face when you consider the extensive use of containers in the cloud and the fact that the modern UI host is a browser rather than a 3270 terminal tied to the back-end hardware.

    Similarly to the last time, one of things that is going to drive suborganizations away from the cloud is the way the cloud has become ensconced in a bureaucratic priesthood just like occurred in the mainframe era. Back then you had suborgs going rogue and buying a VAX for their team to cut their reliance on the mainframe. This allowed them to cut their budgets, but a big motivator was it removed the control of the priesthood. I think we will see similar behaviors with the cloud. The cloud relationship, like the mainframe relationships is landing at the corporate HQ where "big decisions" are made. This more than anything is the root cause of cloud malaise that I am seeing.

        The current push by the cloud providers is provide "PostgreSQL compatible" data stores which have much higher performance numbers.

It is worse than buying Oracle licenses - at least then you ran them on prem. Now you run a closed source db on their servers.

      Lots of companies are looking critically at their cloud computing bills. Not to mention the hilarity that happens when someone posts the customer list on an unsecured cloud server. More and more software packages are advertising their non-subscription model as a feature too.

      ... they could very well run on their own premises, at least partially, for much cheaper ...

      Have you dealt with the nightmare that is IT?

      You might think we'll just run a server on premises but you're missing the thousands of details that will run you ragged dealing with IT.

        Yes.

        So what? I'm not talking about getting Joe-the-accountant to manage the server on his spare time. There are people whose job it is to do IT right. Just like heart surgery and space exploration are very complicated subjects and there are heart surgeons and astronauts to do the job.

        The point is that when you do your own IT - meaning you hire people who build and manage your IT infrastructure correctly, at least the part that covers the base needs of your organization if you still want to retain the cloud

          Sounds like you haven't dealt with IT.

          If your project depends on some IT person doing a lot of things right, good luck.

          There is zero incentive to help you in any way. If everything works great, IT won't even be mentioned.

          And, they have every leverage against you since your project completion depends on them and you have really nothing to offer them.

          If you do the IT yourself or if the IT team are your underlings, maybe. But, any big institution IT is an absolute nightmare to deal with.

    • Well spoken. Computer elites like elites of  any-stripe hatehatehate giving up control over those they consider "lesser" & inferior. Nekbeerdz and C-suites would glue-together  usrland PC keyboard keys given 1/2 a second. 
  • The shift from cloud back to server closets is already happening. Only, this time they are calling it "edge computing".

    Yes, there are lots of nuances like processing a sensor network on-site and only sending aggregate to the cloud, but ultimately it means that less stuff is going to the cloud. And if cloud goes down for any reason, you still get to access the on-site elements...

    I agree that migrations to on-prem will happen - some already have and I read about one every couple of weeks. But I was thinking about another similarity to the mainframe environment recently. Back in 1980, when I first wrote Cobol on a mainframe, we'd submit our compile/link/run jobs, and wait for the printout with the results. Since this was a college environment, that wait was often a couple of hours, unless it was the end of a semester, in which case you may have to wait until the next day.

    All my work is in the cloud these days, usually involving AWS services such as API Gateway, Lambda, DynamoDB, etc. I do consulting work for large corporations, and they usually have a build pipline. So when I'm working on code, I get compiler or linter errors locally, but then I have to give my code to the pipeline and let it build and deploy it. The wait is usually 15 to 30 minutes, but it can be longer if the pipeline has insufficient resources. I've waited hours for a deployment to complete on on occasion.

    In the hey-days of the 90's and early 2000's, most things ran on your local workstation, which was a low-latency heaven. Unfortunately, I fear we've come full circle!

    For modern applications the premise of this story may be somewhat true, but for the world's banks, insurance companies, and governments, the mainframe will remain where it is at. Why? It's very simple. IBM mainframe operating systems are completely backwards compatible with the very first iteration of DOS/360, released in 1966 and IBM mainframes are completely hardware compatible with the first 1965-era IBM 360 mainframes. In short, you can run programs written in 1966 on the most modern IBM mainframes without recompiling the programs and they will work exactly as before with the one notable exception that they will run several orders of magnitude faster. The 64-bit Intel (and AMD) CPUs can execute anything from the DOS era but no modern operating system will support it. The same can be said about 16- and 32-bit Windows apps given that support for those has now been removed. MacOS? Nope. Linux? Nope!

    Now, in theory, you could install the Herclues emulator in the could and run your mainframe apps in the could but I wouldn't recommend it. Hercules emulates the IBM instructions, meaning it's much, much slower than Big Iron. Keep in mind that modern IBM mainframe CPU's now run at 5 ghz. Also, you might have trouble getting access to an operating system to run on it. Older IBM mainframe operating systems are in the public domain and those can be used for many legacy tasks but if your newer apps require features present in a modern one, you're out of luck because IBM is not going to let you keep it in order to run it on a competitor's environment.

    In short, if you are a company or an organization with a large software code base and you've been using mainframes for your computational needs, cloud computing does not offer much of an incentive to move to it.

  • But the "dumb terminals" are usually very capable, powerful desktops and laptops.
    Even Arm and RiscV SBCs are becoming powerful and very power efficient.
    The "cloud" is just keeping us tied to corporate money making machines when we really can do it ourselves.
    My partner pays subscriptions for "cloud" Office 365, a "cloud" accounting package and "cloud" web presence
    for her consultancy, beats me why she would do it.
    She follows advice from The IT Crowd against the advice from the BOFH.

  • Not really, if you work in the industry. Low grade hardware running on low-cost crapware, on the end of an intermittent Internet. Written by an Indian programmer on one dollar ($1) a day.
  • And while there were many things to like about the mainframe (including "crazy high availability numbers which today's cloud vendors can only dream of"), cost was not one of them.

    Did this guy actually work on a mainframe? I did, and I can tell you that uptime wasn't all that great. As a "computer operator" I had to often take the system down to perform various maintenance operations or system updates. By contrast, Azure runs at about 99.995% uptime. https://www.zdnet.com/article/... [zdnet.com] This is in line with my own experience in both Azure and AWS...the systems almost never go down.

  • Companies complain about the cost of Azure and AWS. But the only reason they can self-host cheaper, is that they cut a lot of corners. They don't do proper updates, or backups, or geo-redundancy, or power or internet redundancy. So sure, you can do things "cheaper" yourself, but at much greater risk of downtime or breach, and lower resilience in the face of disaster.

  • No, of course not.

    On-premises cloud is the new mainframe.

    Cloud is just CPU time (etc.) as a service.

    When you say mainframe what you are saying is a monolithic system that takes what you throw at it and offers extreme reliability. You can have that with your own in-house cluster built with full redundancy. That is essentially what a mainframe is, in a box. Instead of multiple identical nodes doing various jobs as needed, they have sub-processors inside the box to do specific jobs. Each approach has its own b

  • We haven't had a good "is cloud the new" discussion in, what? A decade? How very timely of us.

  • Couldn't agree more with the article. I totally agree with the problem is that even developers can become lazy and just want to "yolo shipit" the application to the amazon/gcp/azure mainframe. The management only later cops on that devs are burning cash and then they start to burn cash by asking the developers to "optimise" to reduce the cloud bill - and that requires a redesign of the core components of the application.

Remember the good old days, when CPU was singular?
