Do you remember when Cisco introduced UCS servers in 2009? One of the attributes of Cisco UCS that contributed to its huge success are service profiles: the possibility of describing the configuration and personlity of a server in a declarative language, and deploying it in multiple pieces of hardware. After a while, Cisco extended that concept … Continue reading If you like Cisco UCS or ACI, you are going to love Azure (Stack)
You might have read my previous blog on how important collaboration software can be for creating an effective DevOps culture. A couple of things have happened since I wrote that blog: Azure Functions make serverless computing possible in Azure Microsoft has launched Teams, more or less playing in the same category as Cisco Spark and … Continue reading Bringing together Dev and Ops with Serverless Computing (Azure Functions)
This is an exciting post, since it is the first one I write since I joined the Microsoft team. One of the things that have surprised me is the amount of open source solutions that you can deploy effortlessly in Azure. Services ranging from a simple RHEL or Ubunto machine, to complete open source solutions … Continue reading Using Ansible to Create and Manage Linux Workloads in Azure
Last three years have been the hell of a ride for me personally at Cisco. Ever since Cisco acquired Insieme, I had the privilege of working on this new approach for data center networking. In an extremely exciting moment in the network industry fueled by the SDN hype, it looked as if every network professional suddenly … Continue reading So long Cisco, hello Microsoft!
Imagine you are an IT admin. Your cellular rings while you are drinking your ritual cup of tea in the cafeteria: “why don’t you answer on our Instant Messenger? We have a serious problem in our production environment”. So much for your tea break. Anyhow, back to your desktop, and on to the Incident Management … Continue reading A Recipe for DevOps: APIs + Collaboration + Analytics

If you thought that 2 years after ACI’s launch the speed of innovation would decrease, just have a look at all the new stuff below (and I assure you, it is not all of it). 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
You might remember my old post on Linux container integration with ACI by using the “network=none” option in the old Docker implementation: http://erjosito.tumblr.com/post/110063660087/cisco-aci-and-linux-containers. In the meantime, the networking concept in Docker has considerably evolved, including in the latest releases the concept of network driver plugins (https://docs.docker.com/engine/extend/plugins_network/). Contiv (https://contiv.io) is one of those plugins, that enhances the … Continue reading Demo with Docker containers and Cisco ACI integration: Contiv
