If you are using public Wi-Fi a lot in coffee shops, hotels, malls (you know it is dangerous, right?) or you want to get access to the content that is not accessible in your region then yes you need it. So, you can buy one of those service or if you have Synology device you can configure your own VPN Server for free. Unfortunately, your own VPN Server will address only public Wi-Fi problem, for accessing content that is not available in you region you still need to buy VPN service, unless you have Synology devices in different region.

There are many cases when you want to dynamically add/remove CNAME, A/AAA records to your domain. To do that you should get familiar with yours domain registrar API (if any) and its limits (like requests per day, throttling, etc.).

Before we continue we need to add Docker support to our application we created in Part 1 of this article.

Recently I’ve tried to use official Cosmos DB Emulator on docker , but quickly encountered some issues that I’ll try to address in this article.
