There’s no better way to learn something than to get hands-on. Tigera is excited to present its brand new (and completely free!) self-paced workshops for containers and Kubernetes. Each workshop comes with your own provisioned sample application (Hipstershop) and Calico Cloud lab environment for a limited time.
The first self-paced workshop we’ve launched is on compliance for containers and Kubernetes. Let’s take a closer look at why you should enroll in our compliance workshop and what you’ll gain.
From the Payment Card Industry Data Security Standard (PCI DSS) to the Health Insurance Portability and Accountability Act (HIPAA) to the General Data Protection Regulation (GDPR), most industries must meet certain compliance requirements when it comes to handling personal data. This could mean implementing resource access control, isolating workloads with sensitive data, or enforcing more advanced security controls such as logging all customer confidential data transactions. No matter what sort of controls you need to implement, the compliance auditor will require proof of compliance, such as what security controls are currently in place, whether control changes can be detected, and if compliance can be verified on demand. The ephemeral nature of Kubernetes can make it Continue reading
It took vendors like Cisco years to start supporting routing protocols between MLAG-attached routers and a pair of switches in the MLAG cluster. That seems like a no-brainer scenario, so there must be some hidden complexities. Let’s figure out what they are.
We’ll use the familiar MLAG diagram, replacing one of the attached hosts with a router running a routing protocol with both members of the MLAG cluster (for example, R, S1, and S2 are OSPF neighbors).

The Hedge December update contains information about upcoming episodes and training—listen in for the inside scoop!
My next live training course is coming up on the 16th of December: Troubleshooting. This is one of those classes where I’m taking formal training from a former life (electronic engineering) and applying it to the networking world. From the description—
Troubleshooting is a fundamental skill for all network engineers, from the least to most experienced. However, there is little material on correct and efficient troubleshooting techniques in a network engineering context, and no (apparent) live training in this area. Some chapters in books exist (such as the Computer Networking Problems and Solutions, published in December 2017), and some presentations in Cisco Live, but the level of coverage for this critical skill is far below what engineers working in the field to develop solid troubleshooting skills.
This training focuses on the half-split system of troubleshooting, which is widely used in the electronic and civil engineering domains. The importance of tracing the path of the signal, using models to put the system in context, and the use of a simple troubleshooting “loop” to focus on asking how, what, and why are added to the half-split method to create a complete theory of troubleshooting. Other concepts covered in this course are the Continue reading
Today on the Tech Bytes podcast we explore two outages of big-time cloud applications with sponsor ThousandEyes, a Cisco company. These outages share a common thread, in that the network was up and the applications were reachable, but problems on the backend meant the applications weren’t available. We discuss what happened and offer takeaways to minimize business disruptions.
