Transitioning Away From Legacy IT

One of the more exciting things I saw at Dell Technologies World this week was the announcement by VMware that they are supporting Microsoft Azure now in additional to AWS. It’s interesting because VMware is trying to provide a proven, stable migration path for companies that are wanting to move to the cloud but still retain their investments in VMware and legacy virtualization. But is offing legacy transition a good idea?

Hold On For One More Day

If I were to mention VLAN 1002-1005 to networking people, they would likely jump up and tell me that I was crazy. Because those VLANs are not valid on any Cisco switches save for the Nexus line. But why? What makes these forbidden? Unless you’re studying for your CCIE you probably just know these are bad and move on.

Turns out, they are a legacy transition mechanism from the IOS-SX days. 1002 and 1004 were designed to bridge FDDI-to-Ethernet, and 1003 and 1005 did the same for Token Ring. As Greg Ferro points out here, this code was tightly bound into IOS-SX and likely couldn’t be removed for fear of breaking the OS. The reservation continued forward in all IOS branches except Continue reading

Start with your business goals and decide which metrics are required to accurately measure the state of these goals. For example, say an ISP wishes to ensure that their subscribers get the best performance possible during peak usage time — this can be monitored by measuring the oversubscription ratio and uplink utilization of the terminating device. The required metrics to do this are the number of connected sessions, ifHCInOctets, ifHCOutOctets, ifHCSpeed of the uplink from the terminating device. —Tim Raphael @APNIC

What is the best threat management system for a business network? It’s a difficult question to answer because threat management isn’t about finding a single solution to every problem; it’s about layering multiple solutions in a way that offers the best protection against a variety of threats. —Diana Shtil @Dark Reading

Tomorrow, the House Judiciary Committee will host what’s likely to be a wide-ranging discussion of how social media companies moderate content, in its hearing on Filtering Practices of Social Media Platforms. While the hearing is sure to include some spectacle and grandstanding, make no mistake: This is a deeply serious issue that deserves thoughtful consideration by policymakers, companies, and users alike. Here are a few key themes we Continue reading

VMware and VeloCloud announce their networking and security strategy

It’s been a few months since VMware closed its acquisition of VeloCloud, a prominent SD-WAN provider. In that time, the two companies have worked to integrate their products, and recently they announced a unified strategy called the Virtual Cloud Network.The strategy fully supports the migration of applications and data out of the enterprise data center to the cloud and to branches — and with IoT, pretty much anything can be considered a branch today, as VeloCloud claims to have a customer with ocean-going ships as branches. The result is that many enterprises are in a position where their applications are everywhere, and their data is everywhere. This has profound implications on the network that needs to support all of this.To read this article in full, please click here

Dogfooding Cloudflare Workers

On the WWW team, we’re responsible for Cloudflare’s REST APIs, account management services and the dashboard experience. We take security and PCI compliance seriously, which means we move quickly to stay up to date with regulations and relevant laws.

A recent compliance project had a requirement of detecting certain end user request data at the edge, and reacting to it both in API responses as well as visually in the dashboard. We realized that this was an excellent opportunity to dogfood Cloudflare Workers.

Deploying workers to www.cloudflare.com and api.cloudflare.com

In this blog post, we’ll break down the problem we solved using a single worker that we shipped to multiple hosts, share the annotated source code of our worker, and share some best practices and tips and tricks we discovered along the way.

Since being deployed, our worker has served over 400 million requests for both calls to api.cloudflare.com and the www.cloudflare.com dashboard.

The task

First, we needed to detect when a client was connecting to our services using an outdated TLS protocol. Next, we wanted to pass this information deeper into our application stack so that we could act upon it and Continue reading

HPC Container Security: Fact, Myth, Rumor, And Kernels

It is fair to say that containers in HPC are a big deal. Nothing more clearly shows the critical nature of any technology than watching the community reaction when a new security issue is discovered and released.

In a recent announcement from the team over at Sylabs, they stated that multiple container systems on kernels that do not support PR_SET_NO_NEW_PRIVS were now vulnerable. This was big news, and it obviously spread like a proverbial wildfire through the HPC community, with many mostly voicing their upset that the initial announcement came out at the start of a long holiday weekend …

European Agenda on Digital for Development: Can the Multistakeholder Approach Help?

The year 2017 was an important milestone in moving forward the European agenda for Digital for Development (D4D). The European Commission (EC) paper on mainstreaming digital technologies into EU development policy and the European Council conclusions on Digital for Development have activated the European development community to share opinions and ideas on how to help bridge the global digital divide.

In the past month, we have had a couple of open events in Brussels to discuss this important issue. The European Parliament’s EPP group hosted a public hearing on Digitalisation for Development to collect ideas and to push for more progress. Two weeks later, the EC held the first multistakeholder meeting for Digital4Development with a focus on Africa.

Building a Balanced Agenda

There are a number of pillars of activities that most stakeholders agree on. These include Internet access with a focus on last mile; Internet as an enabler across different sectors; skills; and entrepreneurship. During the recent meetings, the EC, the national development agencies and the private sector showcased impressive and innovative digitalisation programmes.

However, several stakeholders pointed out that while it is important to continue to invest in Internet access, this is no longer enough. We need Continue reading
