Upgrading Cloud Infrastructure Made Easier and Safer Using Cloudflare Workers and Workers KV

Upgrading Cloud Infrastructure Made Easier and Safer Using Cloudflare Workers and Workers KV

This is a guest post by Ben Chartrand, who is a Development Manager at Timely. You can check out some of Ben's other Workers projects on his GitHub and his blog.

At Timely we started a project to migrate our web applications from legacy Azure services to a modern PaaS offering. In theory it meant no code changes.

We decided to start with our webhooks. All our endpoints can be grouped into four categories:

  1. Integration with internal tools i.e. HelpScout, monitoring endpoint for PagerDuty
  2. Payment confirmations
  3. Calendar integrations i.e. Google Calendar
  4. SMS confirmations

Despite their limited number, these are vitally important. We did a lot of testing but it was clear we’d only really know if everything was working once we had production traffic. How could we migrate traffic?

Option 1

Change the CNAME to point to the new hosting infrastructure. This is high risk. DNS takes time to propagate so, if we needed to roll back, it would take time. We would also be shifting over everything at once.

Option 2

Use a traffic manager to shift a percentage of traffic using Cloudflare Load Balancing. We could start at, say, 5% traffic to the new infrastructure Continue reading

Intel announces new data center processors and more

The Consumer Electronics Show (CES) may seem like an odd place to announce server processors, but Intel knows full well the eyes of the tech world are on the show. And what better place to corral a bunch of journalists?First up was shipment of the new Xeon Scalable CPU, code-named Cascade Lake, featuring improved artificial intelligence (AI) and memory capabilities. Cascade Lake is the first to feature support to the company's Optane DC persistent memory and instruction set, called DL Boost, to facilitate AI-based deep learning (DL) inference.Optane memory goes in the memory slots and has the persistence of flash but better performance. Think of it as a cache between the SSD and the main memory. It will also support multiple terabytes of memory per socket.To read this article in full, please click here

Geo IP Databases are Highly Inaccurate

Lots of network monitoring platforms use GeoIP databases to track/monitor sources. These databases are, perhaps, 75% accurate (for some definition of accurate). This is your regular reminder to have a sense of caution about location based on public IP address. John S. and his mother Ann live in the house, which is in Pretoria, the […]

How edge computing can help secure the IoT

Data created by Internet of Things (IoT) sensors must be secured better, say some. A simple password-on-device solution is no longer sufficient thanks to increasing data protection regulations, a new public awareness of tracking, and hugely proliferating devices. A new kind of architecture using Security Agents should be aggressively built into local routers and networks to handle IoT security and computation rather than offloading the number-crunching to a data center or the cloud, or indeed trying to perform it on the resource-limited IoT device, IEEE researchers say. In other words, IoT security should be handled at the network level rather than device for best results.To read this article in full, please click here

The Internet Is Knowledge and Knowledge Is Power

Adisa Bolutife is a 22-year-old open access advocate based in Lagos, Nigeria. A graduate of the University of Lagos with a degree in and electronics engineering, he is passionate about issues related to access, technology, inclusion, and Internet Governance. In 2016, Bolutife founded Open Switch Africa, where he leads a group of students, researchers, and academics to advocate for open access in research, education, and data in Nigeria. He is also a co-founder and director of Digital Grassroots, a global initiative that works to improve digital literacy in local communities. He is an Internet Society 2017 Youth@IGF fellow and an alumnus of the UNESCO Youth Leadership Workshop on Global Citizenship Education, Mozilla Open Leaders, and OpenCon 2017.

Like many people around the world, the Internet has contributed largely to the person I am today – building my knowledge base through access to a wealth of information. Without the Internet, a lot of things would not be as easy as they are right now.

As a recent graduate, I can relate to the fact that the Internet has been extremely helpful in aiding and improving student learning and research, as I can cite academic resources online and watch Continue reading

Coding for Others

Writing code with the mindset that others are going to view and contribute, even for personal projects, improves the overall project and provides benefits to yourself.
