One of the first few things you would do after getting your hands on a new cloud instance is probably to run a few bandwidth measurements on speedtest.net. I certainly do. But it gets a bit tedious having to find out the Singapore servers without a GUI. Fueled by my own laziness, I have created… Continue reading SpeedTest Singapore script
ViewQwest. China. Slow. You can make any sentence with these three words without negating them and the resulting statement will be true.
Network routing to China left quite a bit to be desired, congestion happens with a large number of packet loss during evening peak hours, typically from 8pm onwards. If your purpose of using Lightsail is to serve web content to an audience within China or is pulling contents from China servers, you may want to look elsewhere. Access to the rest of the world is good, as you would expect from an AWS data center.
Traceroute helps you quickly find out the network path and measure the transit delays of packets across the internet. The standard implementation displays only the IP or rDNS entries, which may not allow you to identify the geographic path at first glance.
We love to use Cloudflare CDN because it improves latency and uptime, and the price is just right (free) for the starter pack. Normally, a web server’s ports 80 and 443 would be opened to the public internet, with access restricted by selected IP ranges by either ASN or country, depending on what the administrator… Continue reading Allow only Cloudflare CDN servers to your web servers
If you have been in the market of shopping for a cloud instance, you will notice the offerings are deceptively similar: 1 vCPU + 1GB memory with a 20GB disk and 1TB bandwidth, for the same price. Are they really similar though? Far from it.
Let’s say you have a Cloud VM lying around with, it is entirely possible to turn it into a personal proxy for your internet traffic. It is probably not going to help you unlock region-protected content since services like Netflix and Hulu would probably have blocked the IP range operated by hosting service providers, but… Continue reading Using your cloud instance as a proxy with Dante server
So you’ve got your first Linux VM, hurray! Here is a quick prep guide to get it up to speed. In this example (and throughout this blog), I’ll assume you’re using the Debian-based Ubuntu 18.04 LTS – which is ideal as it comes with newer software packages and is quite a bit easier to manage… Continue reading Quick config and optimization of your cloud instance
In the course of the past few months, I have deep dived into a cloud journey over a myriad of service providers. From the big boys like Azure, AWS, and GCP, to the more traditional VPS hosting companies and niche cloud players such as Alibaba Cloud and Oracle Cloud. I have been a Windows guy… Continue reading Greater purpose – the journey leading to this blog
