Kubernetes enabled qualities small companies didn't dream before.

I can implement zero downtime upgrades easily with Kubernetes. No more late-day upgrades and late-night debug sessions because something went wrong, I can commit any time of the day and I can be sure that upgrade will work.

My infrastructure is self-healing. No more crashed app server.

Some engineering tasks are standardized and outsourced to the professional hoster by using managed serviced. I don't need to manage operating system updates and some component updates (including Kubernetes).

My infrastructure can be easily scaled horizontally. Both up and down.

I can commit changes to git to apply them or I can easily revert them. I know the whole history perfectly well.

I would need to reinvent half of Kubernetes before, to enable all of that. I guess big companies just did that. I never had resources for that. So my deployments were not good. They didn't scale, they crashed, they required frequent manual interventions, downtimes were frequent. Kubernetes and other modern approaches allowed small companies to enjoy things they couldn't do before. At the expense of slightly higher devops learning curve.
