Old way (Adobe Commerce Cloud / PaaS):
Think of it like renting an apartment where you still have to fix the leaky tap, repaint the walls, and upgrade the wiring yourself. Adobe gave you the servers/cloud infrastructure, but your team (or an agency) still had to handle updates, patches, scaling, and maintenance.
Adobe Commerce Cloud / PaaS means you need to manage servers, deployments, updates, or patches etc. by manually
New way ACaCS ( ACCS)/ ( SaaS):
Now it’s like staying in a serviced apartment/hotel. Adobe takes care of everything behind the scenes — the building, repairs, upgrades, security — and you just focus on living there (i.e., running your store: adding products, managing customers, running sales).
ACCS means you don’t manage servers, deployments, updates, or patches anymore — Adobe does it all for you automatically, and you just log in and run your online store.
