The Re-Emergence of the Operating System

Each of the major infrastructure silos has to operate with some fixed environment in mind

Compute started its major architectural transition several years ago with the introduction of virtualization. If you pay attention to any of the IT noise today, it should be clear that storage and networking are going through their own architectural evolutions as well. But another shift is also underway: applications are fundamentally changing as well.

An interesting dynamic in all of this is that it is near impossible for each of the four major IT areas to undergo simultaneous, coordinated evolution. Change is hard enough on its own, but changing multiple variable at once makes it difficult to anchor to anything substantial. And when change does occur along multiple fronts at the same time, the task of determining causation for new found results is challenging at best.

Understanding that business underlies much of the change, the best that the industry can collectively do is to take some things as fixed and then change around that. And so we evolve each of the silos somewhat independently, trying hard to keep in mind that the environment into which they plug is also changing. At our best, we try to intersect the various changes. But when we miss, we tend to aim towards slotting into current architectural paradigms, because that allows us the best chance to make a meaningful difference in production environments. Indeed, always playing out ahead of the horizon might be great for making future progress, but it makes building a business around the resulting innovation nigh impossible.

Moving forward

And so IT as a whole continues the trudge forward.

Each of the major infrastructure silos—compute, storage, and networking—has to operate with some fixed environment in mind. The most basic thing to attach to is application infrastructure. While virtualization has made compute containers that make applications portable (the reason dynamic and change are so prominent in most marketing materials), the applications themselves have remained largely static.

Except, of course, that they haven’t.

Application architectures

Anyone watching the major web-scale players (think: Facebook, Google, Twitter, and the like) will know that the architecture for their applications is actually significantly different than what most enterprises currently think of. Applications tend to be flatter and more distributed, typically running on bare metal to avoid some of the virtualization overhead that exists in a pure hypervisor environment.

This new breed of scale-out applications would appear to mark the beginning of the application evolution. If this is truly a trend that will only increase, how will it impact the evolution of the other silos?

Software-defined everything

The prevailing chatter across the whole of IT is about software-defined everything. The view is that compute, storage, and networking will all work in cahoots to meet application requirements. The rise of controller-based architectures is prominent in both networking and storage roadmaps, and the compute side of the house embraced central control awhile back.

But what happens if the underlying assumption that applications emerge largely unscathed turns out not to be true?

It could be that the future of datacenter architectures will hinge not on the supporting infrastructure but on the applications themselves. If this is true, we could see a re-emergence of something that we haven’t really talked about in quite awhile: the operating system itself. Sure, there is still talk about Linux and all the server tools that come with it, but the actual operating system hasn’t materially changed in quite some time.

Learning from web-scale applications

If we learn anything from the web-scale companies pushing the boundaries for application performance, it should be that the future is not necessarily about the containers in which applications run. It could be about the underlying OS itself. What if the reason massively scaled companies are embracing bare metal isn’t only about the cost? There is certainly a performance aspect to it as well.

One somewhat uncomfortable conclusion here would be that all the infrastructure work involved in handling application portability across a containerized infrastructure could be somewhat transient. I don’t mean to suggest that it is not useful; there will be a relatively long transition to any kind of new application architecture. And even if there is a transition, the persistence of mainframes should tell us all that no change is absolute or all-encompassing. But a scenario where pockets of new-era applications co-exist in data centers with legacy applications seems likely. We are already seeing this with Hadoop, but I would expect to see more applications built on new architectures.

But this does mean that future-proofing datacenter investments requires a bit more nuance than just buying and planning on scale. Highly-distributed application architectures are even more dependent on east-west traffic. For every 1 byte of traffic going in and out of the datacenter, close to 1 Gigabyte transits the datacenter fabric in some current applications. This ratio likely gets even more aggressive over time.

The bottom line

How all of this plays out is anyone’s guess. We will certainly end up with a hybrid environment supporting all kinds of application architectures making use of various underlying infrastructure architectures. But none of us should be surprised when the industry starts talking a bit more broadly about the role of the operating system going forward. And if you are making plans based on a set of assumptions anchored to current architectures, it might be worth expanding the strategic aperture some to consider how this impacts current plans.

And as a final thought, if the operating system changes, is it still defined by the server, or do we end up with large, distributed operating systems? Put differently, what is the definition of the underlying platform? Are we looking at a new era of platform that includes all of compute, storage, networking, and applications? The implications would be dramatic.

As software organizations continue to invest in achieving Continuous Delivery (CD) of their applications, we see increased interest in microservices architectures, which–on the face of it–seem like a natural fit for enabling CD. In microservices (or its predecessor, “SOA”), the business functionality is decomposed into a set of independent, self-contained services that communicate with each other via an API. Each of the services has their own application release cycle, and are developed and depl...
With microservices, SOA and distributed architectures becoming more popular, it is becoming increasingly harder to keep track of where time is spent in a distributed application when trying to diagnose performance problems. Distributed tracing systems attempt to address this problem by following application requests across service boundaries, persisting metadata along the way that provide context for fine-grained performance monitoring.
The battle over bimodal IT is heating up. Now that there’s a reasonably broad consensus that Gartner’s advice about bimodal IT is deeply flawed – consensus everywhere except perhaps at Gartner – various ideas are springing up to fill the void. The bimodal problem, of course, is well understood. ‘Traditional’ or ‘slow’ IT uses hidebound, laborious processes that would only get in the way of ‘fast’ or ‘agile’ digital efforts. The result: incoherent IT strategies and shadow IT struggles that lead ...
More and more companies are looking to microservices as an architectural pattern for breaking apart applications into more manageable pieces so that agile teams can deliver new features quicker and more effectively. What this pattern has done more than anything to date is spark organizational transformations, setting the foundation for future application development. In practice, however, there are a number of considerations to make that go beyond simply “build, ship, and run,” which changes ho...

In most cases, it is convenient to have some human interaction with a web (micro-)service, no matter how small it is. A traditional approach would be to create an HTTP interface, where user requests will be dispatched and HTML/CSS pages must be served. This approach is indeed very traditional for a web site, but not really convenient for a web service, which is not intended to be good looking, 24x7 up and running and UX-optimized. Instead, talking to a web service in a chat-bot mode would be muc...
In the Bimodal model we find two areas of IT - the traditional kind where the main concern is keeping the lights on and the IT focusing on agility and speed, where everything needs to be faster. Today companies are investing in new technologies and processes to emulate their most agile competitors. Gone are the days of waterfall development and releases only every few months. Today's IT and the business it powers demands performance akin to a supercar - everything needs to be faster, every sc...

Are you someone who knows that the number one rule in DevOps is “Don’t Panic”? Especially when it comes to making Continuous Delivery changes inside your organization? Are you someone that theorizes that if anyone implements real automation changes, the solution will instantly become antiquated and be replaced by something even more bizarre and inexplicable?
Welcome to the first top DevOps news roundup of 2016! At the end of last year, we saw some great predictions for 2016.
