The combined company will be worth roughly $146 billion. T-Mobile CEO John Legere will lead the new firm and Sprint CEO Marcelo Claure will serve on the board.
Cloud computing is a lot more than “someone else’s computer” and it annoys the hell out of me when people keep trotting out this tired old excuse. There is much more to service delivery than compute power. You do yourself and your customers a disservice if you don’t do your research.
A few years ago it was fashionable to dismiss cloud as “just someone else’s computer”, e.g.:
There is no cloud. It's just someone else's computer. pic.twitter.com/9d3S5chWQq

In a time when most cloud computing was Infrastructure as a Service, there was an element of truth to it. But…
The problem is that there’s still people thinking this. Check these recent tweets.
These people don’t realize that the world has moved on a long way. There is much more to cloud computing than just “someone else’s computer.”
Consider a simple example, like email. To provide email services from “my computer” I also need power, cooling, rack space, servers, storage, networking, operating system, software, application configuration and maintenance, etc…not to mention the operational expertise to keep it all going.
As a Product Manager at Cloudflare, I spend quite a bit of my time talking to customers. One of the most common topics I'm asked about is configuration management. Developers want to know how they can write code to manage their Cloudflare config, without interacting with our APIs or UI directly.
Following best practices in software development, they want to store configuration in their own source code repository (be it GitHub or otherwise), institute a change management process that includes code review, and be able to track their configuration versions and history over time. Additionally, they want the ability to quickly and easily roll back changes when required.
When I first spoke with our engineering teams about these requirements, they gave me the best answer a Product Manager could hope to hear: there's already an open source tool out there that does all of that (and more), with a strong community and plugin system to boot—it's called Terraform.
This blog post is about getting started using Terraform with Cloudflare and the new version 1.0 of our Terraform provider. A "provider" is simply a plugin that knows how to talk to a specific set of APIs—in this case, Cloudflare, but Continue reading
So, I recently went to my first RSA Conference. It’s something I’ve had on my radar for a while but never had the opportunity to do. However, with Security Field Day coming up later this year I thought it was high time I went to see what everything was about. Here are some ideas that I came up with during my pilgrimage to the big security conference.
The INE Bootcamps site is finally here! We constantly strive to make our products and buying experience better, which is why we decided to give our bootcamps their very own website. As INE continues to grow, we plan on rolling out even more bootcamp dates, locations and types, all of which can now be found at bootcamps.ine.com.
Ready to get started on your certification journey? Check out our Bootcamps Site for yourself.
In part one of our series on ECMP, we discussed the basics of ECMP, the recent changes that have been made and Cumulus’ part in moving the ball forward for Linux networking. Now, it’s time to get a little more technical and review how advancements in ECMP development for IPv4 and IPv6 have made ECMP what it is today — and what it can be in the near future.
Hashing algorithms
Hashing algorithms are the biggest component of ECMP behavior, so it makes sense for us to talk for a moment about what we specifically mean when we refer to each one.
1.) Per-packet hash
This hash was the original hashing algorithm used in the kernel’s ECMP behavior. It is trivially simple to understand as it basically uses a pseudo random number in the kernel at the time packet is being processed (jiffies) to determine which link in an ECMP bundle the traffic will use for egress. With this algorithm in place, each packet for a single flow could use a different link to get to the destination. This leads to all kinds of bad behaviors in TCP and higher level applications/protocols Continue reading
The framework simplifies the connection between GCP services and a GCP-hosted Kubernetes cluster or an on-premises Kubernetes cluster.
The company has developed Ethernet switch chips for data centers. It competes against Broadcom, Barefoot, and Cavium.
Ericsson brings 5G to Italy; Cisco enhances its SAN offerings; NetFoundry and AWS team up on IoT.
Thanks to all who joined us for the Pulse Secure 2018 Next-Gen Data Center Networking Report Webinar: A Trust Model for Multi-Cloud Networks and Applications Beyond Zero Trust.
The next phase of the operator's 5G trials will include at least 100 base stations in each of the five test cities. The trials will use equipment from multiple vendors including Ericsson, Nokia, Huawei, and ZTE.
In this episode of Packet Pushers, it’s AWS networking. You use AWS and think you know what you need to know? Maybe, but our guest today can probably share a thing or two you didn t even know were things when it comes to networking in the Amazon public cloud.
Our guest is Nick Matthews, Principal Solutions Architect at Amazon Web Services. Nick focuses on networking and security.
Nick pinged us, hoping to share his perspective on cloud networking from the inside. Come and have a look.
We talk about how networking basics do–and don’t–map to the cloud, and how the architecture of cloud applications influence network design and operations.
We also explore AWS networking elements under the hood, such as Hyperplane, and how trends such as SD-WAN and SDN influence Amazon networking.
