The case for open standards: an M&A perspective
Very few organizations use IT equipment supplied by a single vendor. Where heterogeneous IT environments exist, interoperability is key to achieving maximum value from existing investments. Open networking is the most cost effective way to ensure interoperability between devices on a network.
Unless your organization was formed very recently, chances are that your organization’s IT has evolved over time. Even small hardware upgrades are disruptive to an organization’s operations, making network-wide “lift and shift” upgrades nearly unheard of.
While loyalty to a single vendor can persist through regular organic growth and upgrade cycles, organizations regularly undergo mergers and acquisitions (M&As). M&As almost always introduce some level of heterogeneity into a network, meaning that any organization of modest size is almost guaranteed to have to integrate IT from multiple vendors.
While every new type of device from every different vendor imposes operational management overhead, the impact of heterogeneous IT isn’t universal across device types. The level of automation within an organization for different device classes, as well as the ubiquity and ease of use of management abstraction layers, both play a role in determining the impact of heterogeneity.

Terraforming Cloudflare: in quest of the optimal setup
This is a guest post by Dimitris Koutsourelis and Alexis Dimitriadis, working for the Security Team at Workable, a company that makes software to help companies find and hire great people.
This post is about our introductive journey to the infrastructure-as-code practice; managing Cloudflare configuration in a declarative and version-controlled way. We’d like to share the experience we’ve gained during this process; our pain points, limitations we faced, different approaches we took and provide parts of our solution and experimentations.
Terraform world
Terraform is a great tool that fulfills our requirements, and fortunately, Cloudflare maintains its own provider that allows us to manage its service configuration hasslefree.
On top of that, Terragrunt, is a thin wrapper that provides extra commands and functionality for keeping Terraform configurations DRY, and managing remote state.
The combination of both leads to a more modular and re-usable structure for Cloudflare resources (configuration), by utilizing terraform and terragrunt modules.
We’ve chosen to use the latest version of both tools (Terraform-v0.12 & Terragrunt-v0.19 respectively) and constantly upgrade to take advantage of the valuable new features and functionality, which at this point in time, remove important limitations.

InfluxDB 2.0
docker run --name influxdb -p 9999:9999 quay.io/influxdb/influxdb:2.0.0-alphaPrometheus exporter describes an application that runs on the sFlow-RT analytics platform that converts real-time streaming telemetry from industry standard sFlow agents. Host, Docker, Swarm and Kubernetes monitoring describes how to deploy agents on popular container orchestration platforms.
- sflow-rt-analyzer,
URL: http://10.0.0.70:8008/prometheus/analyzer/txt - sflow-rt-dump,

The first collects metrics about the performance of the sFlow-RT analytics engine, the second, all the metrics exported by the sFlow agents, and the third, is a flow metric (see Flow metrics with Prometheus and Grafana).
Updated 19 October 2019, native support for Prometheus export added to sFlow-RT, URLs 1 and 2 modified to reflect new API.

Islamabad Chapter Brings First Internet Governance Event to Quetta, Pakistan
The 5th Pakistan School on Internet Governance (pkSIG 2019) was successfully held last month in Quetta, Pakistan. This represents a significant achievement for the Internet Society Pakistan Islamabad Chapter as it played an instrumental role in bringing the first-ever Internet Governance event to the provincial capital of Balochistan.
For those who may not know, Balochistan has the largest land area among the four provinces of Pakistan, yet it is the least populated and least developed. Only 27% of its population lives in urban areas and Internet penetration is low. Finding adequate sponsors, and more importantly, diversity among the students to participate was a critical concern. But, pkSIG 2019 in Quetta proved to be one of the best editions of this school.
Over 60 people (one-third of them female) registered for the event, including students, professionals, startup founders, speakers, and some guests who showed keen interest in the program. Following a four-week long process of registration and shortlisting, 35 students were selected for pkSIG 2019 and five were awarded fellowships. Since all the sessions were livestreamed, a sizeable audience participated online as well. (The sessions and presentations are available online.)
“It’s our fifth consecutive year conducting pkSIG – Continue reading
VMware NSX Killed My EVPN Fabric
A while ago I had an interesting discussion with someone running VMware NSX on top of VXLAN+EVPN fabric - a pretty common scenario considering:
- NSX’s insistence on having all VXLAN uplink from the same server in the same subnet;
- Data center switching vendors being on a lemming-like run praising EVPN+VXLAN;
- Non-FANG environments being somewhat reluctant to connect a server to a single switch.
His fabric was running well… apart from the weird times when someone started tons of new VMs.

Red Hat Ansible Tower offers value by allowing automation to scale in a checked manner - users can run playbooks for only the processes and targets they need access to, and no further.
Not only does Ansible Tower provide automation at scale, but it also integrates with several external platforms. In many cases, this means that users can use the interface they are accustomed to while launching Ansible Tower templates in the background.
One of the most ubiquitous self service platforms in use today is ServiceNow, and many of the enterprise conversations had with Ansible Tower customers focus on ServiceNow integration. With this in mind, this blog entry walks through the steps to set up your ServiceNow instance to make outbound RESTful API calls into Ansible Tower, using OAuth2 authentication.
This is part 3 in a multi-part series, feel free to refer to part 1 and part 2 for more context.
The following software versions are used:
- Ansible Tower: 3.4, 3.5
- ServiceNow: London, Madrid
If you sign up for a ServiceNow Developer account, ServiceNow offers a free instance that can be used for replicating and testing this functionality. Your ServiceNow instance needs to be able Continue reading
