Pragmatic EVPN Designs

While running the Using VXLAN And EVPN To Build Active-Active Data Centers workshop in early December 2019 I got the usual set of questions about using BGP as the underlay routing protocol in EVPN fabrics, and the various convoluted designs like IBGP-over-EBGP or EBGP-between-loopbacks over directly-connected-EBGP that some vendors love so much.

I got a question along the same lines from one of the readers of my latest EPVN rant who described how convoluted it is to implement the design he’d like to use with the gear he has (I won’t name any vendor because hazardous chemical substances get mentioned when I do).

Juniper bolsters wireless security; fights against encrypted malicious threats

Juniper is filling out its enterprise security portfolio this week by integrating support for its Mist wireless customers and adding the capability for customers to gain better visibility and control over encrypted traffic threats.With the new additions, Juniper is looking to buttress its ability to let users secure all traffic traversing the enterprise network via campus, WAN or data center. The moves are part of Juniper's grand Connected Security platform that includes a variety of security products including its next-generation firewalls that promise to protect networked resources across infrastructure and endpoints.To read this article in full, please click here

Cisco goes to the cloud with broad enterprise security service

Cisco has unveiled a cloud-based security platform it says will go a long way in helping customers protect their far-flung networked resources.Cisco describes the new SecureX service as offering  an open, cloud-native system that will let customers detect and remediate threats across Cisco and third-party products from a single interface. IT security teams can then automate and orchestrate security management across enterprise cloud, network and applications and end points.Network pros react to new Cisco certification curriculum “Until now, security has largely been piecemeal with companies introducing new point products into their environments to address every new threat category that arises,” wrote Gee Rittenhouse senior vice president and general manager of Cisco’s Security Business Group in a blog about SecureX.To read this article in full, please click here

Seamless remote work with Cloudflare Access

The novel coronavirus is actively changing how organizations work in real-time. According to Fortune, the virus has led to the “world’s largest work-from-home experiment.” As the epidemic crosses borders, employees are staying home and putting new stress on how companies manage remote work.

This is only accelerating an existing trend, however. Remote work has gained real traction in the last decade and Gartner projects that it will only continue. However, teams which are moving to a distributed model tend to do so slowly. When those timelines are accelerated, IT and security administrators need to be able to help their workforce respond without disrupting their team members.

Cloudflare Access can help teams migrate to a model that makes it seamless for users to work from any location, or any device, without the need for lengthy migrations or onboarding sessions. Cloudflare Access can be deployed in less than one hour and bring SaaS-like convenience and speed to the self-hosted applications that previously lived behind a VPN.

Leaving the castle-and-moat

When users share a physical space, working on a private network is easy. Users do not need clunky VPN clients to connect to the resources they need. Team members physically sit close Continue reading

Topology matters: how port-per-workload management strategies no longer hold up

In the beginning, there were switches. And connected to these switches were servers, routers and other pieces of gear. These devices ran one application, or at a stretch, multiple applications on the same operating system and thus IP stack. It was very much one-server-per-port; the SQL Server was always on port 0/8, and shutting down port 0/8 would affect only that machine.

This is no longer true, as network engineers well know. Physical hardware no longer dictates what, where, and how servers and other workloads exist. Cloud computing, multi-tenant virtual infrastructures and dynamically reallocated virtual resources mean that one port can cover 20 or 200 servers. Conversely, link aggregation and other forms of port density protocols mean that one server can have fault-tolerant aggregated links across one, five or 50 ports.

A new way of looking at switching—as a logical, rather than physical, topology—is required. In this view, switches aren’t so much pieces of the network architecture themselves, but simply ports that can be used to set up much more complex logical links. This article will focus on two main concepts: routing protocols (to allow better utilization of underutilized switching links) and switching protocols such as STP (those used to Continue reading

Socratic vs. Euclidean Forms of API Documentation

I was emailing a service about their documentation and while their doc was good, about one particularly tricky concept they told me that once you use it for a while, that’s when you’ll understand it.

In other words: you’ll only understand it after you understand it.

I didn’t like that response. I want documentation that takes me from an unproductive newbie to a somewhat functioning journeyperson. Not an expert, but I want to get stuff done as soon as possible. And for that you need to understand the mental model behind the API. Otherwise, how do you know how to make anything happen?

I realize it’s hard to make good documentation. I spent a lot of time writing Explain the Cloud Like I'm 10 just to communicate the mental model behind the cloud. It’s not easy.

Then I read that something that showed me there are two different styles of documentation: Euclidean and Socratic:

Euclidean - state your axioms and let users derive the rest. Easiest for the API provider, but hardest on the user. This is the most common form of documentation. You see it all the time. Each entry point in the API is sort of Continue reading
