I wanted to avoid posting on Prophecy and I know this will be a very unpopular low vote post and damage my ranking.
But I can't help myself again!
These slides just screams "Buy Oracle" even if it is $100+ USD and you need to fill in that WB form to receive the quarterly dividends to ensure you are not taxed too much.
There is also a partnership fee when joining the Oracle Partner Network. I know as the company I work for is part of the OPN.
On top of that, there are ongoing certification fees and certification expires after 2 years. - but of course you have a choice to do it once and not do it again.
Then of course there's commissions etc... to Oracle for being a partner which cuts into the margins.
On the move to Oracle Cloud I have a feel this will cost quite a bit and need new hires to maintain emite and Snare on Oracle Clloud Infrastructure. Hence the mention about the hosting cost. Hopefully for shareholders the containers before the move were running latest versions so it would be less labour intensive. Prophecy had no choice because it is obvious that some of their government and NGO clients are making the move to Oracle Cloud. This is why it makes more sense to buy Oracle shares instead.
I could get into more detail on Virtual container image maintenance etc.. on OCI but that will be beyond the scope of this post and will just confuse everyone more. You can do a google search on Patch Hypervisor or Host and Virtualbox for a basic primer of what this could involve but I can assure it is a pain when you patch your Linux system only to find your little Virtual machines and docker stuff suddenly don't work.
Having said that, I think the cycle of moving off deprecated systems in OCI on average is about about 2-3 years.

You are probably aware from the last Sydney meetup about my background in Oracle Cloud so feel free to probe me a bit more on this.
