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.

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.

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.
Infrastructure as Code (IaC) can work great for a single user, but what happens when lots of people are pushing changes? Scott Lowe and guest Tim Davis talk about the challenges of scaling IaC beyond a single engineer and provide practical insight into ways to address these challenges. Tim is Developer Advocate at Env0.

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:
We will show real-world improvements for several performance metrics.
We have added and improved lots of features since the initial launch.
We will cover the most common use cases and explain how Automatic Platform Optimization could be fined-tuned.
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.

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?
Whenever you’re choosing a data store for your network automation solution you have to consider a number of aspects including:
This section explains the process how to build an on-prem Cisco Viptela based SD-WAN control plane system. It starts by setting up an enterprise Certificate Server using the Cisco CSR1000V cloud router. Next, it goes through the process of root certificate generation. The rest of the chapter explains the initial configuration and certification installation processes from vManage, vBond, and vSmart viewpoints.

Palo Alto Networks CloudBlades and AWS Transit Gateway Connect can automate the setup of SD-WAN networks from branch offices to the public cloud. Here's how.

What percentage of business-impacting application outages are caused by networks? According to a recent survey by the Uptime Institute, about 30% of the 300 operators they surveyed, 29% have experienced network related outages in the last three years—the highest percentage of causes for IT failures across the period.
A secondary question on the survey attempted to “dig a little deeper” to understand the reasons for network failure; the chart below shows the result.
We can be almost certain the third-party failures, if the providers were queried, would break down along the same lines. Is there a pattern among the reasons for failure?
Configuration change—while this could be somewhat managed through automation, these kinds of failures are more generally the result of complexity. Firmware and software failures? The more complex the pieces of software, the more likely it is to have mission-impacting errors of some kind—so again, complexity related. Corrupted policies and routing tables are also complexity related. The only item among the top preventable causes that does not seem, at first, to relate directly to complexity is network overload and/or congestion problems. Many of these cases, however, might also be complexity related.
The Uptime Institute draws this same lesson, though Continue reading
Palo Alto Networks sponsors today's Tech Bytes. We drill into key differentiators of the Prisma SD-WAN platform including its use of machine learning, the unique CloudBlades offering, and its app-defined approach to path selection and policy enforcement. Our guest from Palo Alto Networks is Rohan Grover, Senior Director of Product Management.
