Data Privacy Day 2021 – Looking ahead at the always on, always secure, always private Internet
Welcome to Data Privacy Day 2021! Last year at this time, I was writing about how Cloudflare builds privacy into everything we do, with little idea about how dramatically the world was going to change. The tragedy of the COVID-19 pandemic has reshaped the way we go about our daily lives. Our dependence on the Internet grew exponentially in 2020 as we started working from home, attending school from home, and participating in online weddings, concerts, parties, and more. So as we begin this new year, it’s impossible to think about data privacy in 2021 without thinking about how an always-on, always secure, always private Internet is more important than ever.
The pandemic wasn’t the only thing to dramatically shape data privacy conversations last year. We saw a flurry of new activity on data protection legislation around the globe, and a trend toward data localization in a variety of jurisdictions.
I don’t think I’m taking any risks when I say that 2021 looks to be another busy year in the world of privacy and data protection. Let me tell you a bit about what that looks like for us at Cloudflare. We’ll be spending a lot of time in Continue reading
Businesses Can’t Afford to Lose Trust in the Encrypted Economy, and Neither Can You
End-to-end encrypted platforms have become an important means to establish online trust for businesses and individuals globally – and law enforcement/intelligence services are struggling to keep up.
Their unfamiliarity and uncertainty is reflected in the ambiguity of political discourse on the subject. On one hand, the European Union endorses strong encryption within data protection laws such as GDPR. On the other, attempts to intercept end-to-end-encrypted communication between suspicious parties resurface over and over again.
The Council Resolution on Encryption, adopted by the Council of the European Union, is the latest example. Politicians continue to strive for both strong end-to-end encryption and getting targeted access to information when – from a security and technology standpoint – the two concepts are at odds. Symbiosis is only possible in political rhetoric.
As the co-founder of an end-to-end encrypted cloud service, I am deeply concerned at how demands for access to encrypted data will affect the security of thousands of businesses and the millions of clients who rely on them in the EU and worldwide.
The Digital Economy Is at Risk
Our digital economy depends on the widespread use of strong encryption. This includes end-to-end encryption, within organizations of all shapes and sizes.
Build Virtual Lab Topology: VirtualBox Support
When I blogged about release 0.2 of my lab-building tool, Kristian Larsson was quick to reply: “now do vrnetlab”. You could guess what my reply was (hint: “submit a pull request”), but I did realize I’d have to add multi-provider support before that would make sense.
Release 0.3 adds support for multiple virtualization providers. You can run six different platforms on vagrant-libvirt (assuming you build the boxes), and I added rudimentary support for Vagrant provider for VirtualBox:

Day Two Cloud 082: You Don’t Need A Service Mesh
Today's Day Two Cloud podcast speaks with the creator of the Envoy proxy, Matt Klein, about the challenges of networking, load balancing, and service discovery in microservices architectures. The upshot? Depending on what you're trying to do and why, you may not need a service mesh. You may not need microservices. Sometimes a VM is just right.
