Do I need API gateway for cloud and on-prem at the same time?

Not necessarily.
You only need an API Gateway if it solves a problem you actually have. For cloud + on-prem at the same time—a hybrid setup—an API Gateway is often useful, but it’s not mandatory.
When you do need one
Use an API Gateway if you want to:
- expose the same APIs to both cloud and on-prem consumers
- centralize authentication/authorization
- do rate limiting, throttling, or quotas
- handle routing to different backends
- enforce TLS termination, logging, monitoring
- hide internal services behind one consistent endpoint
- support API versioning and governance
When you may not need one
You might skip it if:
- the system is small/simple
- services are only used internally
- you already have a reverse proxy or ingress doing the needed job
- cloud and on-prem apps talk directly over private network links
- you don’t need centralized API policy enforcement
Common hybrid pattern
In hybrid environments, teams often use:
- API Gateway in cloud for public/external traffic
- internal gateway or reverse proxy on-prem for local services
- private connectivity between cloud and on-prem
Bottom line
If your goal is just connectivity between cloud and on-prem, no, not always.
If your goal is to manage, secure, and standardize API access across both, then yes, an API Gateway is usually a good idea.
If you want, I can help you decide based on your architecture and show a simple hybrid reference design.
