Tucha started as an ISP in 2005 and became the first IaaS provider in Ukraine in 2012, now offering hundreds of virtual machines. The document discusses their adherence to open-source software principles and outlines IPv4 addressing plans for various server types within their infrastructure. Additionally, it mentions tasks for improving network management, such as naming conventions and cross-replication for MySQL servers.

- 2. About Tucha Here I’ll be telling something about our company (started as an ISP in 2005), our cloud experience (back in 2012 we were the first who started to provide IaaS in Ukraine), our cloud’s volume (several hundreds of virtual machines), our adherence to OSS ideology and so on. It would be amazing to have it illustrated somehow :)
