The #IoT and #DNS | @ExpoDX #BigData #AI #IIoT #DigitalTransformation

The Internet of Things will result in an increasing need for scalable DNS services

JANUARY 8, 2014 02:00 PM EST

When we talk about the impact of BYOD and BYOA and the Internet of Things, we often focus on the impact on data center architectures. That's because there will be an increasing need for authentication, for access control, for security, for application delivery as the number of potential endpoints (clients, devices, things) increases. That means scale in the data center.

What we gloss over, what we skip, is that before any of these "things" ever makes a request to access an application it had to execute a DNS query. Every. Single. Thing.

Maybe that's because we assume DNS can handle the load. So far it's done well. You rarely, if ever, hear of disruptions or outages due directly to the execution of DNS. Oh, there has been some issues with misconfiguration of DNS and of exploitation of DNS (hijacking, illicit use in reflection attacks, etc...) but in general there's rarely a report that a DNS service was overwhelmed by traffic and fell over.

dns-center-iotThat is exactly the problem. We've been successful with scaling DNS.

"Success breeds complacency. Complacency breeds failure. Only the paranoid survive." - Andrew Grove.

In the face of rapidly expanding endpoints (things), it behooves us all to take a second look at DNS and ensure it's ready to meet the challenge.

This is not just about availability. Remember operational axiom #2 - as load increases, performance decreases. That's true for DNS, too. It doesn't get a pass. That's why it's called an axiom, after all, because it's kind of the law, like gravity.

Browsers do a good job of obfuscating the latency incurred by DNS, and native mobile applications never show such gory details, so it's difficult for a user to separate latency associated with an overloaded DNS service from a generally poorly performing application. Not that they care, actually. A slow app is a slow app to an end user. They aren't interested in the gory details, they're interested in speedy applications. Period.

Interestingly, though, the Internet of Things is made up of more than just users. Lots of devices and applications make up the myriad endpoint "overlay" network created by connections between these devices and "things".

Devices don't care about latency (unless of course they're being driven by users, then the users care, but the devices surely don't). But the thing about DNS is that the latency is generally incurred at initial connection time. There's no way to differentiate before a connection is made whether it's a device or a real, live person on the other end. Even after a connection is made, UDP isn't exactly the most verbose of protocols and it's nearly impossible to differentiate via UDP, too. You've only got a few headers, and none of them offer insight into what kind of endpoint is making the request.

The imperative, then, is to ensure really fast connections and responses to every single query.

That may mean you need to reevaluate your DNS infrastructure to ensure it's ready to handle the coming flood of "things". Test and verify the maximum queries per second (QPS) your systems can manage while maintaining what your business defines as acceptable latency. Make sure to plot out latency based on connections and queries per second to get an idea of at what point your DNS starts to become part of the performance problem.

As the Internet expands and more devices and users are accessing your applications, it would be a mistake to forget about DNS. We all know the old saying about "assuming" things - and that certainly holds true when you simply assume your DNS is able to handle the increasing load.

Be paranoid. Test often. CYA(pps).


DXWorldEXPO LLC, the producer of the world's most influential technology conferences and trade shows has announced the conference tracks for CloudEXPO | DXWorldEXPO 2018 New York.

DXWordEXPO New York 2018, colocated with CloudEXPO New York 2018 will be held November 11-13, 2018, in New York City.

Digital Transformation (DX) is a major focus with the introduction of DXWorldEXPO within the program. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term.

A total of 88% of Fortune 500 companies from a generation ago are now out of business. Only 12% still survive. Similar percentages are found throughout enterprises of all sizes.

Cloud computing is now being embraced by a majority of enterprises of all sizes. Yesterday's debate about public vs. private has transformed into the reality of hybrid cloud: a recent survey shows that 74% of enterprises have a hybrid cloud strategy. Meanwhile, 94% of enterprises are using some form of XaaS - software, platform, and infrastructure as a service.

With major technology companies and startups seriously embracing Cloud strategies, now is the perfect time to attend and learn what is going on, contribute to the discussions, and ensure that your enterprise is on the right path to Digital Transformation.

Every Global 2000 enterprise in the world is now integrating cloud computing in some form into its IT development and operations. Midsize and small businesses are also migrating to the cloud in increasing numbers.
