ExaGrid updates and streamlines its backup appliances

I'm a sucker for the underdog, so shame on me for focusing on the big guys for so long. It's time to change that with some news from ExaGrid, a competitor of Dell EMC and HP Enterprise in the data backup appliance market.Earlier this month, ExaGrid announced it has increased the capacity of its Tiered Backup Storage appliances while also reducing its offerings from nine systems to seven. Appliances of any size can be mixed and matched in a cluster of up to 32 appliances.ExaGrid also changed the naming convention of the appliances to better reflect their capacity. For example, the discontinued bottom-of-the-line EX3000 had 3TB of full backup capacity, while the new bottom-end appliance is the EX6, with 6TB of full backup capacity storage.To read this article in full, please click here

BGP: What is border gateway protocol, and how does it work?

Finding the best way to get from Point A to Point B is easy if you’re drawing a straight line on a piece of paper, but when Point A is your computer and Point B is a website halfway around the world, things get a bit trickier.In the latter case, Border Gateway Protocol (BGP), the routing protocol used by the global internet, is used to find the best path by weighing the latest network conditions based on reachability and routing information. BGP manages how data packets get delivered between the large networks that make up the internet and makes it possible for the internet as we know it to operate efficiently.What is Border Gateway Protocol? BGP has been called the glue of the Internet and the postal service of the internet. One comparison likens BGP to GPS applications on mobile phones. If you were driving from Boston to Los Angeles, the GPS app decides the best route possible using existing knowledge of road conditions, traffic jams, and whether you want to travel on a toll road. Sometimes, the shortest path is not always the best path. BGP is like having a continuously updated map of the internet from Continue reading

Data Privacy Day 2021 – Looking ahead at the always on, always secure, always private Internet

Data Privacy Day 2021 - Looking ahead at the always on, always secure, always private Internet
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:

The Future of Network Engineering; some possibilities through 2040 and beyond

Incident 1: October, 2006 Sydney Australia – Simply put, someone hit me with a tough question. Totally out of the box and very much to the point, so to the point that it took me years to swallow the impact. The question was an innocent one asked by one of the sharpest software engineers I […]

Serious 10-year-old flaw in Linux sudo command; a new version patches it

Linux users should immediately patch a serious vulnerability to the sudo command that, if exploited, can allow unprivileged users gain root privileges on the host machine.Called Baron Samedit, the flaw has been “hiding in plain sight” for about 10 years, and was discovered earlier this month by researchers at Qualys and reported to sudo developers, who came up with patches Jan. 19, according to a Qualys blog. (The blog includes a video of the flaw being exploited.)To read this article in full, please click here

The Hedge Podcast #66: Daniel Migault and the ADD Working Group

The modern DNS landscape is becoming complex even for the end user. With the advent of so many public resolvers, DNS over TLS (DoT) and DNS over HTTPS (DoH), choosing a DNS resolver has become an important task. The ADD working group will, according to their page—

…focus on discovery and selection of DNS resolvers by DNS clients in a variety of networking environments, including publicnetworks, private networks, and VPNs, supporting both encrypted and unencrypted resolvers.

In this episode of the Hedge, Daniel Migault joins Alvaro Retana and Russ White to discuss Requirements for Discovering Designated Resolvers, draft-box-add-requirements-02.

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.

Automating data center expansions with Airflow

Automating data center expansions with Airflow

Cloudflare’s network keeps growing, and that growth doesn’t just come from building new data centers in new cities. We’re also upgrading the capacity of existing data centers by adding newer generations of servers — a process that makes our network safer, faster, and more reliable for our users.

Connecting new Cloudflare servers to our network has always been complex, in large part because of the amount of manual effort that used to be required. Members of our Data Center and Infrastructure Operations, Network Operations, and Site Reliability Engineering teams had to carefully follow steps in an extremely detailed standard operating procedure (SOP) document, often copying command-line snippets directly from the document and pasting them into terminal windows.

But such a manual process can only scale so far, and we knew must be a way to automate the installation of new servers.

Here’s how we tackled that challenge by building our own Provisioning-as-a-Service (PraaS) platform and cut by 90% the amount of time our team spent on mundane operational tasks.

Choosing and using an automation framework

When we began our automation efforts, we quickly realized it made sense to replace each of these manual SOP steps with an API-call equivalent and Continue reading
