A Sneak Peek at the “Calico Certified Operator: AWS Expert” Course

This One’s All About You

Recently, we released our new “Calico Certified Operator: AWS Expert” course. You can read more about why we created this course and how it can benefit your organization in the introductory blog post.

This blog post is different; it’s an opportunity for you, the potential learner, to get a glimpse of just a few interesting parts of the course. You won’t learn all the answers here, but you’ll learn some of the questions!

If you find that you already know the answers, then you’re all set to grab yourself a shiny badge. If not, consider taking some time to invest in your personal development and pick up some new knowledge in AWS and container networking—really current and relevant knowledge.

Let’s take a sneak peek at what the “Calico Certified Operator: AWS Expert” course has to offer.

Considering Cluster Types

There are several ways to build a Kubernetes cluster in AWS. There is no single “right” way. What are the considerations your organization should have in mind, and how can you help your organization make an informed choice?

You will review, amongst many other things, how to decide:

Viewing enabled and running services on Linux with systemctl

A vast majority of Linux systems these days are using systemd – a suite of programs aimed at managing and interconnecting different parts of the system. Systemd started replacing the init process back in 2014 and is now the first process that starts when most Linux systems boot. To get a quick peek, you can run a command like this, which verifies that process 1 is indeed systemd. On this system, two additional systemd processes are currently also running.$ ps -C systemd PID TTY TIME CMD 1 ? 00:00:59 systemd <=== 1244 ? 00:00:00 systemd 54429 ? 00:00:00 systemd To see a little more detail, try the command below. The blank within the quotes is meant to prevent related processes like systemd-journald from showing up in the list.To read this article in full, please click here

Cisco preps now for the hybrid workforce

Work-from employees will no longer be treated as a second-class citizen, which means they will get best-in-class technology including SD-WAN appliances, cellular backup alternatives, zero trust security support and maybe even battery backup.That’s at least part of the plan for hybrid workers now and moving forward, said Cisco’s Todd Nightingale, executive vice president and general manager of the company’s Enterprise Networking & Cloud business. “The ‘return-to-office’ concept is a myth--it’s a world we have left behind.”To read this article in full, please click here

Hedge 93: Dinesh Dutt and Observability

We talk a lot of about telemetry in the networking world, but generally as a set of disconnected things we measure, rather than as an entire system. We also tend to think about what we can measure, rather than what is useful to measure. Dinesh Dutt argues we should be thinking about observability, and how to see the network as a system. Listen in as Dinesh, Tom, And Russ talk about observability, telemetry, and Dinesh’s open source network observability project.

How to Listen to the Hedge

The Hedge is over 90 episodes now … I’m a little biased, but I believe we’re building the best content in network engineering—a good blend of soft skills, Internet policy, research, open source projects, and relevant technical content. You can always follow the Hedge here on Rule 11, of course, but it’s also available on a number of services, including—

I think it’s also available on Amazon Music, but I don’t subscribe to that service so I can’t see it. You can check the Podcast Directory for other services, as well. If you enjoy the Hedge, please post a positive rating so others can find it more easily.

Feds’ demand for software standards could boost enterprise security

Enterprises can look for more transparency from software vendors after the Biden Administration’s recent mandate that software bills of materials be provided by companies attempting to do business with the federal government.Software bills of materials, frequently abbreviated to SBOMs, aren’t a new concept. The idea comes from the manufacturing sector, where it’s often crucial for buyers to fully understand the components and materials that were used to make a particular piece of equipment.The 10 most powerful companies in enterprise networking 2021 For example, a train engine might contain parts that aren’t rated for certain levels of vibration stress, making it unsuitable for use on a particular type of track. The goal of an SBOM is similar, listing all the proprietary, open source, and licensed components being used in a particular piece of software, so that a buyer can review it and check whether any of those components are outdated or insecure.To read this article in full, please click here
