Thoughts from the clouds
After some questions in my previous blog post CLI-based analysis of an ExpressRoute private peering I decided to write an addition that includes what Expressroute Global Reach looks like for the CLI lover. In essence, Global Reach allows to use Microsoft’s backbone network for onprem-to-onprem communication. But how does it do it exactly? I have … Continue reading ExpressRoute Global Reach under the covers

Other posts in the series: Part 1: Intro and SDN Plugin Part 2: Internet and Intra-cluster Communication Part 3: Inter-Project and … Continue reading A day in the life of a packet in Azure Redhat Openshift (part 2)
I have been wanting to look into this for a while now, and I finally found a good excuse to do it. You might have read my series of posts on AKS networking, the goal of this is doing something similar with Azure Redhat Openshift (ARO). This is part 1 of a blog series around … Continue reading A day in the life of a packet in Azure Redhat Openshift (part 1)
I have to apologise because of skipping last month’s update, what has led to a massive update today.

Without any doubt, … Continue reading Tetration analytics, ACI 2.0 and much more!
Lately I have been involved in quite some conversations, where organisations have shown a lot of interest in the integration between Cisco ACI and F5 BigIP and BigIQ (or should I say iWorkflow?). As you might know, Cisco ACI offers the option to integrate L4-L7 services in the network. What does this mean? Optionally, you … Continue reading What do Cisco ACI, microsegmentation, service insertion, REST and Docker containers have in common?
Do you have a network lab to try out new technologies? Then you might have experienced this problem: you finished testing technology A, and you start testing technology B. For that you need to reconfigure your devices, obviously. Now you need to try out something new in technology A, for example a new functionality brought … Continue reading Using NX-API to deploy full networks
Lately there seems to be a lot of buzz in the press about combining Cisco ACI and VMware NSX to achieve a comprehensive SDN solution. Nothing bad with that, other than it creates some times the perception that NSX and ACI need themselves mutually. And hence this post, since I disagree with this perspective. First … Continue reading Are ACI and NSX complementary solutions?

I recently got from F5 colleagues the idea, why not working on an automation use case showing the integration between ACI and F5. One use case they see often in their customer basis is autoscaling of Web farms: some system is looking at the load on the servers, and if that load grows over a … Continue reading The network is *not* in my way
