    Removing WALinuxAgent from your Azure instance

    Azure’s supplied Linux images come preinstalled with the Azure Linux Agent, a process that manages virtual machine interaction with the Azure Fabric Controller, such as providing the oh-so-useful availability status and the VM name to Azure. It also performs self-updates, by the way.

  • Installing Caddy as a service in your cloud instance

    Installing Caddy as a service in your cloud instance

    Caddy should be everyone’s server of choice. Especially lazy people, and that’s everyone. This blog is served by Caddy. It is a modern web server written in Go. It does automatic HTTPS configuration. TF is automatic you ask? Take this blog for example – if it were to run in Nginx, the config file would look like this:

    If you have taken a look in your January 2020 invoice from your GCP subscription, you would notice a new line that resembles this:

That is 750 hours per month of free usage, which you can either leave it on 24/7, or spin up 750 instances for 1 hour. Either way, it is within the free tier.

    AWS Lightsail US$3.5/mo instance reviewed

    This is a personal, independent review of the service which I have paid for, and is in no way affiliated with AWS.

    As mentioned in the inauguration article, I was in the market for a VPS with excellent internet connectivities to improve my streaming experience for content hosted in certain countries.

  • Comparing cloud instance performance across different providers

    Comparing cloud instance performance across different providers

    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.

    Quick config and optimization of your cloud instance

    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 than CentOS.

    Setting hostname and timezone

    After SSH-ing into the terminal, the first two things you’d want to do is update the hostname and timezone settings of your VM. These can be done by the following commands:
