You can still use your disks to install these versions of your applications (and subsequently check for updates to these versions). The latest versions (CC2015/2017), would be particularly suitable for your retina screen, but are only available on subscription.
download the programs for use from the cloud
I suspect Adobe has lost a ton of business because of this silly "cloud" name <hey! let's call it something with cloud in it, that's what everybody's doing these days!>
In reality there's no cloud. The application installs and runs on your machine just like it always has, no change.
The difference is only in the license checks, and the payment method. Yes, you pay per month, and once a month the application calls home to verify that you did so. But if you didn't, perhaps because your Visa card was renewed and you forgot to update your payment info - it will still run for 99 days before shutting down.
It should be said that any which way you do the math, your total cost, if you want the apps to stay up to date, is less than what it would be with a perpetual license. A lot of people can't wrap their heads around that, but it's a fact.
Oh, one more thing. This is Apple. That means no guarantees that old software will run without several problems, or run at all. You may have to get on board the upgrade train whether you want it or not.
