The initial effort to decrease hosting total cost of ownership (TCO) is wrapping up. This squad was hugely successful by reducing day to day disk use of up to 30% for large deployments. The ticket covering this work will be released in CHT 5.0.
However, while testing this initial Hosting TCO 1.0 feature, it became clear that there was another big disk use pain that our deployments feel: the huge amount of disk space the CHT needs to upgrade. This can be up to 5x of free space needed. For example, if a large deployment had 1.8 TB of data and was on a 4TB disk they would have 55% of free disk space - plenty of room to grow for months, or possibly years! However, they would need to get to upgrade to a 9TB disk to have enough free space to upgrade. This is a massive imposition.
To better visualize the issue, here’s a chart where you can see an impressive >30% gain that was achieved labeled “TCO 1.0”. As well, you can see the ~500% ephemeral space needed for the upgrade - this is labelled “TCO 2.0” - as this is where the focus of 2.0 will be:
Hence, Hosting TCO 2.0 has been born. The squad will be composed of exactly the same members as the current squad, but with a focus on reducing disk space during upgrades.
For anyone interested in joining the squad or dropping in on our weekly call, please see the calendar and check for the Tuesday “Hosting TCO Squad Call”. All are welcome!
