Introducing VMware Transit Connect for networking and security on VMware Cloud on AWS

As you migrate and expand your deployments on VMware Cloud on AWS, your network connectivity provides the foundational infrastructure for all workloads in your SDDCs. When you then scale across multiple SDDCs — which also need to network with several data centers and tens or even hundreds of VPCs — scaling network connectivity becomes a critical challenge.  

In this context, we’re excited to announce a number of new networking and security capabilities on VMware Cloud on AWS. 

• SDDC Groups – a way to organize SDDCs together for ease of management
• VMware Transit Connect –high bandwidth, resilient connectivity for SDDCs in an SDDC Group
• Multi-Edge SDDCs – the ability to add network capacity for north-south traffic to the SDDC

Together, these new features enable seamless connectivity to your SDDCs from on-prem data centers and AWS VPCs while unlocking the capacity you need to efficiently drive your workloads in the cloud. 

Let’s take a closer look at each one. 

SDDC Groups 

SDDC Groups enable customers to manage multiple SDDCs as a single logical entity. This simplifies operations while maintaining the flexibility that customers rely on. SDDCs in a Group can be interconnected with VMware Transit Connect, and Continue reading

Can You Spare a Minute? Network Time Security Featured on The Hedge Podcast

Are you interested in finding out more about Network Time Protocol (NTP), Network Time Security (NTS), and discovering why synchronized time is an essential foundation for online security?

Today is International Podcast Day, so why not spend it listening to the The Hedge Podcast #49: Karen O’Donoghue and Network Time Security.

Network Time Protocol (NTP) is one of the oldest Internet protocols in use. It enables the synchronization of clocks on computer networks to within a few milliseconds of standard universal coordinated time (UTC).  Accurate time is also a critical component for online security, and many security mechanisms, such as Transport Layer Security (TLS) and digital signature creation and verification, depend on accurate timekeeping. 

Updated Mechanism 

NTP’s security mechanisms, however, were designed back in an era when the risk of attack was unlikely. Due to the continued expansion of the Internet, these mechanisms have become outdated. Work has been underway for many years in the Internet Engineering Task Force (IETF) Network Time Protocol Working Group to develop replacement technology, which will help to secure the Internet’s time synchronization infrastructure well into the future. The result of this work is in the Continue reading

You Can’t Do Everything, And That’s Okay

You’re a responsible human–a reliable person who does everything that’s expected and more. Congratulations! Here’s more work to do.

Yep, that’s the rub. If you’re good at your job and other people notice, you get never-ending opportunities to prove once again how good you are. More work to do, and more work to do, and more. The balance in your life is lost as you drown under a pile of opportunities and challenges with deliverables, due dates, and project managers scheduling recurring meetings to get status updates.

No Good Deed Goes Unpunished

If you’ve been through a few jobs, no doubt you’re familiar with this cycle. You leave the old job with a sense of relief, having transitioned your projects to others in a ceremony known as “the hand-off.” You chuckle a bit to yourself as your co-workers and manager who clearly didn’t grasp what all you were handling go glassy-eyed as you talk them through it.

You start the new job with a lightness in your heart. No projects. No due dates. No recurring meetings. The anxiety of getting familiar with a new company, figuring out your role, learning the politics, sure–there’s all that to contend with. But Continue reading

Nigeria’s IXPs – Enabling Better Connectivity, Faster Internet Delivery, and Improving Internet Service

Nigeria grew its local Internet traffic from  30% to 70% in the past eight years, connecting more people, increasing speed, and reducing costs. They did this through Internet Exchange Points (IXPs), according to the Internet Society report Anchoring the African Internet Ecosystem: Lessons from Kenya and Nigeria’s Internet Exchange Points Growth.

Between 2012 and 2020, the number of peering networks has grown from 30 to 71 and new exchange platforms have been set up in Abuja, Kano, and Port Harcourt. More networks and more IXPs increased the amount of Internet traffic exchanged in Nigeria from 300 Mbps to peak traffic of 125 Gbps in Lagos.

Muhammed Rudman started the Internet Exchange Point of Nigeria (IXPN) in 2006, when the industry was developing. Most networks did not peer in Nigeria. One major submarine cable, Sat3, offered services across the country with others getting service via VSATs. This meant ninety-nine percent of websites were hosted abroad.

“The terrain was tough,” says Rudman, an IT veteran and founding Chief Executive Officer of IXPN, which is based in Lagos, Nigeria’s largest city. Approaching Internet service providers, he was often asked how many networks were already peering. Without any networks exchanging traffic, he’d often hear, “When you Continue reading

Python Pieces: PyEnv and Venvs

In my last post, we talked about PyEnv and how it can help manage your local Python environments. As it turns out it can also help you manage virtual environments as well! However – pursuing this functionality took me down a rabbit hole that was a bit deeper than expected. The way that PyEnv works causes some behaviors (and on my end assumptions) to change which made me start questioning some of the things that I’ve always just taken for granted. In other words – prepare yourself to go down the rabbit hole with me.

At first glance PyEnv promised the same sort of awesome automagically context switching craziness that we saw previously work with Python versions. However – the virtual environment management implementation with PyEnv felt rather foreign (and maybe a little clunky?) to me. Most notably, as I pointed out in my last post, the .zshrc alias provided to make the auto activation piece work slows down my terminal immensely which is why I omitted using it. A slow terminal is about the worst thing I can think of…

That said – I still think it’s worth reviewing what it can offer so you can Continue reading

Introducing Cloudflare Radar

Unlike the tides, Internet use ebbs and flows with the motion of the sun not the moon. Across the world usage quietens during the night and picks up as morning comes. Internet use also follows patterns that humans create, dipping down when people stopped to applaud healthcare workers fighting COVID-19, or pausing to watch their country’s president address them, or slowing for religious reasons.

And while humans leave a mark on the Internet, so do automated systems. These systems might be doing useful work (like building search engine databases) or harm (like scraping content, or attacking an Internet property).

All the while Internet use (and attacks) is growing. Zoom into any day and you’ll see the familiar daily wave of Internet use reflecting day and night, zoom out and you’ll likely spot weekends when Internet use often slows down a little, zoom out further and you might spot the occasional change in use caused by a holiday, zoom out further and you’ll see that Internet use grows inexorably.

And attacks don’t only grow, they change. New techniques are invented while old ones remain evergreen. DDoS activity continues day and night roaming from one victim to another. Automated scanning tools look Continue reading

Speeding up HTTPS and HTTP/3 negotiation with… DNS

In late June, Cloudflare's resolver team noticed a spike in DNS requests for the 65479 Resource Record thanks to data exposed through our new Radar service. We began investigating and found these to be a part of Apple’s iOS14 beta release where they were testing out a new SVCB/HTTPS record type.

Once we saw that Apple was requesting this record type, and while the iOS 14 beta was still on-going, we rolled out support across the Cloudflare customer base.

This blog post explains what this new record type does and its significance, but there’s also a deeper story: Cloudflare customers get automatic support for new protocols like this.

That means that today if you’ve enabled HTTP/3 on an Apple device running iOS 14, when it needs to talk to a Cloudflare customer (say you browse to a Cloudflare-protected website, or use an app whose API is on Cloudflare) it can find the best way of making that connection automatically.

And if you’re a Cloudflare customer you have to do… absolutely nothing… to give Apple users the best connection to your Internet property.

The Next Generation of Cognitive Campus Workspaces

Campus networks are undergoing another massive transition in the COVID teleworking era. With this fundamental shift and as administrators consider an interconnected IoT (Internet of Things) environment, the boundary between the office, home, teleworker and user is converging. Security concerns with ever-increasing threat vectors are substantiated. How does one secure an IoT environment and guard against malware and outbreaks? How is the network impacted as some workloads shift to the cloud? Why do we cope with wired and wireless silos? The challenge lies in successfully transitioning the existing siloed campus into an integral data-driven model for clients, users and devices from IoT to cloud with a common experience, while addressing security and availability needs with lower operational costs. These are the key requirements of the third-generation campus evolution as shown in the figure below.

Recovering deleted files on Linux with testdisk

When you delete a file on a Linux system, it isn’t necessarily gone forever, especially if you just recently deleted it.Unless you rubbed it out with a tool such as shred, the data will still be sitting on your disk—and one of the best tools for recovering deleted files, testdisk, can help you rescue it. While testdisk has a wide range of functionality including recovering lost or damaged partitions and making non-booting disks bootable again, it’s also frequently used to restore files that were deleted by mistake.In this post, we’ll take a look at how you can recover deleted files using testdisk and what each step in the process looks like. Since the process requires quite a few steps, you’re likely to feel more comfortable running through them once you’ve done it a few times.To read this article in full, please click here
