Repost: Using MP-TCP to Utilize Unequal Links

In the Does Unequal-Cost Multipathing Make Sense blog post I wrote (paraphrased):

The trick to successful utilization of unequal uplinks is to use them wisely […] It’s how multipath TCP (MP-TCP) could be used for latency-critical applications like Siri.

Minh Ha quickly pointed out (some) limitations of MP-TCP and as is usually the case, his comment was too valuable to be left as a small print at the bottom of a blog post.

NetApp dumps its HCI hardware in favor of Kubernetes

NetApp, one of many players in the hyperconverged infrastructure (HCI) hardware business, plans to end production of its NetApp HCI hardware and focus instead on its Project Astra Kubernetes platform.HCI is split into two categories, software and hardware. On the software side, it's roughly an even split in marketshare between Nutanix and VMware. On the hardware side, IDC and Gartner both list HCI leaders as HP Enterprise, Dell Technology, Cisco Systems, and "the rest of the market." You can guess what category NetApp falls into.

Heavy Networking 567: Why You’ll Use A Service Provider Edge Cloud (Sponsored)

In today's sponsored Heavy Networking podcast, Juniper Networks is here to make the case that service providers are building cloud services at the edge that enterprises can take advantage of. Joining us is Kevin Hutchins, SVP, Strategy & Product Management at Juniper, to assert that service providers can thrive and compete in a cloud-based economy, and that Juniper will be a key part of that ecosystem.

Introduction To gRPC

As the world of network automation continues to evolve, we are seeing different options emerge in how we programmatically interface with our devices. In this episode we take a look at one of the newest and more interesting methods, gRPC. gRPC was developed by Google as a way to execute remote procedure calls in the orchestration of their system and includes such concepts as Protocol Buffers, authentication, bidirectional streaming, and flow control. Join us as we dive into how gRPC works, why it’s different than what you may already know, and why you may want to look into using it to orchestrate your infrastructure.

The History of Identity with Pamela Dingle

While identity is not directly a networking technology, it is closely adjacent to networking, and a critical part of the Internet’s architecture. In this episode of the History of Networking, Pamela Dingle joins Donald Sharpe and Russ White to discuss the humble beginnings of modern identity systems, including NDS and Streettalk.

Docker Series B: More Fuel To Help Dev Teams Get Ship Done

Today we’re excited and humbled to announce Docker’s Series B raise of $23 million to accelerate our mission of delivering tools development teams love to quickly take their ideas from code to cloud. The round was led by Tribe Capital with participation from our existing investors, Benchmark and Insight Partners. Arjun Sethi, Tribe co-founder and partner, will join the Docker board. 

This would not have been possible without the Docker team: Thank you for giving each other your best, every day, despite the disruptions of the refocusing, the pandemic, the overnight switch to work-from-home, and so much more. We also thank our developer community of users, contributors, customers, partners, and Docker Captains – your enthusiastic engagement throughout this past year was invaluable.

Hit Refresh

Tribe sees in Docker what we saw in November 2019 when we refocused the company: the opportunity to build on the bottoms-up developer love of the Docker experience and provide a collaborative app development platform for development teams to accelerate getting their ideas from code to cloud. And that’s just what we did.

Key inputs to Tribe’s investment decision were our results this last year, which included attracting 80,000 developer participants to DockerCon 2020, adding Continue reading

Automatic Platform Optimization post-launch report

Last year during Birthday Week, we announced Automatic Platform Optimization for WordPress (APO): smart HTML caching for WordPress sites using Cloudflare. Initial testing across various WordPress sites demonstrated significant improvements in performance metrics like Time to First Byte (TTFB), First Contentful Paint (FCP), and Speed Index. We wanted to measure how APO impacted web performance for our customers since the launch.

In the blog post, we answer the following questions:

• How fast is Automatic Platform Optimization? Can you demonstrate it with data?

We will show real-world improvements for several performance metrics.

• Is Automatic Platform Optimization flexible enough to integrate smoothly with my WordPress site?

We have added and improved lots of features since the initial launch.

• Will Automatic Platform Optimization work when used with other plugins?

We will cover the most common use cases and explain how Automatic Platform Optimization could be fined-tuned.

Measuring performance with WebPageTest

We use WebPageTest as a go-to tool for synthetic testing at Cloudflare. It measures web performance metrics in real browsers, is highly programmable, and could scale to test millions of sites per day. Among the benefits of synthetic testing are easy to produce results and their relatively high reproducibility.

Ransomware: How to make sure backups are ready for a real attack

The best way to avoid paying ransom to attackers who have infected your systems with ransomware is to have those systems adequately backed up so you can wipe them and restore them from safe backups. Here are several options for making sure those backups are up to the task.In this article, backup refers to any system that you're going to use to respond to a ransomware attack, including old-school backup systems, replication systems, and modern hybrid systems that support backup and disaster recover. For simplicity’s sake, they’ll all be referred to as backup here. More about backup and recovery:To read this article in full, please click here

Using YAML Instead of Excel in Network Automation Solutions

One of the attendees of our network automation course asked a question along these lines:

In a previous Ansible-based project I used Excel sheet to contain all relevant customer data. I converted this spreadsheet using python (xls_to_fact) and pushed the configurations to network devices accordingly. I know some people use YAML to define the variables in Git. What would be the advantages of doing that over Excel/xsl_to_fact?
