Innovation Myths

Innovation has gained a sort-of mystical aura in our world. Move fast and break stuff. We recognize and lionize innovators in just about every way possible. The result is a general attitude of innovate or die—if you cannot innovate, then you will not progress in your career or life. Maybe it’s time to take a step back and bust some of the innovation myths created by this near idolization of innovation.

You can’t innovate where you are. Reality: innovation is not tied to a particular place and time. “But I work for an enterprise that only uses vendor gear… Maybe if I worked for a vendor, or was deeply involved in open source…” Innovation isn’t just about building new products! You can innovate by designing a simpler network that meets business needs, or by working with your vendor on testing a potential new product. Ninety percent of innovation is just paying attention to problems, along with a sense of what is “too complex,” or where things might be easier.

You don’t work in open source or open standards? That’s not your company’s problem, that’s your problem. Get involved. It’s not just about protocols, anyway. What about certifications, training, and Continue reading

Injecting Machine Learning And Bayesian Optimization Into HPC

No matter what kind of traditional HPC simulation and modeling system you have, no matter what kind of fancy new machine learning AI system you have, IBM has an appliance that it wants to sell you to help make these systems work better – and work better together if you are mixing HPC and AI. …

Injecting Machine Learning And Bayesian Optimization Into HPC was written by Timothy Prickett Morgan at The Next Platform.

What are data centers? How they work and how they are changing in size and scope

A data center is the physical facility providing the compute power to run applications, the storage capabilities to process data, and the networking to connect employees with the resources needed to do their jobs.Experts have been predicting that the on-premises data center will be replaced by cloud-based alternatives, but many organizations have concluded that they will always have applications that need to live on-premises. Rather than dying, the data center is evolving.It is becoming more distributed, with edge data centers springing up to process IoT data. It is being modernized to operate more efficiently through technologies like virtualization and containers. It is adding cloud-like features such as self-service. And the on-prem data center is integrating with cloud resources in a hybrid model.To read this article in full, please click here

What are data centers? How they work and how they are changing in size and scope

A data center is a physical facility that enterprises use to house their business-critical applications and information. As they evolve from centralized on-premises facilities to edge deployments to public cloud services, it’s important to think long-term about how to maintain their reliability and security.What is a data center? Data centers are often referred to as a singular thing, but in actuality they are composed of a number of technical elements. These can be broken down into three categories: Compute: The memory and processing power to run the applications, generally provided by high-end servers Storage: Important enterprise data is generally housed in a data center, on media ranging from tape to solid-state drives, with multiple backups Networking: Interconnections between data center components and to the outside world, including routers, switches, application-delivery controllers, and more These are the components that IT needs to store and manage the most critical resources that are vital to the continuous operations of an organization. Because of this, the reliability, efficiency, security and constant evolution of data centers are typically a top priority. Both software and hardware security measures are a must.To read this article in full, please click here

The Week in Internet News: New York City Sued for Homework Gap

A virtual gap: Homeless advocates and legal groups have sued New York City for a lack of reliable Internet access in the city’s 27 homeless shelters, Reuters on WTVBam.com reports. Thousands of students living in the homeless shelters are struggling to keep up with virtual school during the COVID-19 pandemic, the plaintiffs say. The city has promised to install WiFi service in the shelters. New York City recently returned to virtual school after COVID-19 rates ticked up.

Repair it yourself: The European Parliament has voted to make it easier to repair electronic devices outside of the company that sold them, Euronews.com says. The legislation would allow independent repairs without hurting the value of the device during trade in, a move that’s a “major blow” to big device makers.

Device spying: The Singapore-based developer of smartphone application Muslim Pro, targeted at Muslim users, has denied allegations that it is selling the personal data to the U.S. military, The Straits Times reports. Developer Bitsmedia says it is immediately ending relationships with its data partners, however. Vice.com recently reported that the app was among several selling personal data to the U.S. military.

Seeing is believing: a client-centric specification of database isolation

Seeing is believing: a client-centric specification of database isolation, Crooks et al., PODC’17.

Last week we looked at Elle, which detects isolation anomalies by setting things up so that the inner workings of the database, in the form of the direct serialization graph (DSG), can be externally recovered. Today’s paper choice, ‘Seeing is believing’ also deals with the externally observable effects of a database, in this case the return values of read operations, but instead of doing this in order to detect isolation anomalies, Crooks et al. use this perspective to create new definitions of isolation levels.

It’s one of those ideas, that once it’s pointed out to you seems incredibly obvious (a hallmark of a great idea!). Isolation guarantees are a promise that a database makes to its clients. We should therefore define them in terms of effects visible to clients – as part of the specification of the external interface offered by the database. How the database internally fulfils that contract is of no concern to the client, so long as it does. And yet, until Crooks all the definitions, including Adya’s, have been based on implementation concerns!

Improving the Resiliency of Our Infrastructure DNS Zone

Improving the Resiliency of Our Infrastructure DNS Zone

In this blog post we will discuss how we made our infrastructure DNS zone more reliable by using multiple primary nameservers to leverage our own DNS product running on our edge as well as a third-party DNS provider.

Improving the Resiliency of Our Infrastructure DNS Zone

Authoritative Nameservers

You can think of an authoritative nameserver as the source of truth for the records of a given DNS zone. When a recursive resolver wants to look up a record, it will eventually need to talk to the authoritative nameserver(s) for the zone in question. If you’d like to read more on the topic, our learning center provides some additional information.

Here’s an example of our authoritative nameservers (replacing our actual domain with example.com):

~$ dig NS example.com +short
ns1.example.com.
ns2.example.com.
ns3.example.com.

As you can see, there are three nameservers listed. You’ll notice that the nameservers happen to reside in the same zone, but they don’t have to. Those three nameservers point to six anycasted IP addresses (3 x IPv4, 3 x IPv6) announced from our edge, comprising data centers from 200+ cities around the world.

The Problem

We store the hostnames for all of our machines, both the ones at the Continue reading

Internet Society Continues Strong Support for the IETF’s Critical Work on Open Standards

large meeting room with many people sitting on chairs

Open standards and the role they play are an important part of what makes the Internet the Internet. A fundamental building block of the Internet and everything it enables, open standards allow devices, services, and applications to work together across the interconnected networks that make up the Internet that we depend on every day. 

In fact, every moment you are online, even just reading this blog post, you are relying on open standards such as DNS, HTTP, and TLS. They are a critical property of what we call the Internet Way of Networking.

Since its inception, the Internet Engineering Task Force (IETF) – a global community of thousands of engineers who are working each day to create and improve open standards to make the Internet work better – has been at the center of technical innovation for the global Internet. In addition to the standards themselves, the open processes and principles through which they are developed ensure the evolution of Internet technologies that meet the need of the growing number of devices and uses that empower people around the world to connect, share, learn, and more. This places the work of the IETF, and other groups focused on open Continue reading

Zero trust planning: Key factors for IT pros to consider

Moving away from VPNs as a means to protect corporate networks at the perimeter and moving toward zero-trust network access requires careful enterprise planning and may require implementing technologies that are new to individual organizations.ZTNA employs identity-based authentication to establish trust with entities trying to access the network and grants each authorized entity access only to the data and applications they require to accomplish their tasks. It also provides new tools for IT to control access to sensitive data by those entities that are deemed trusted.To read this article in full, please click here

Worth Exploring: Pluginized Protocols

Remember my BGP route selection rules are a clear failure of intent-based networking paradigm blog post? I wrote it almost three years ago, so maybe you want to start by rereading it…

Making long story short: every large network is a unique snowflake, and every sufficiently convoluted network architect has unique ideas of how BGP route selection should work, resulting in all sorts of crazy extended BGP communities, dozens if not hundreds of nerd knobs, and 2000+ pages of BGP documentation for a recent network operating system (no, unfortunately I’m not joking).
