I'm weighing the pros and cons of sticking with AWS for everything versus utilizing a hybrid approach where I run most workloads on a cheaper provider or an on-prem setup. My plan is to handle compute and databases on a cheaper provider like Hetzner or on-prem while using AWS for managed services that add real value, such as ECR, S3, Secrets Manager, and potentially SQS/SNS in the future. I've had good experiences with my own servers, and I find them easier to manage than some AWS options. I'd like to know if this hybrid model is practical for small teams or early-stage businesses. Are there major drawbacks I should be aware of, like networking issues, costs, or reliability concerns? Also, is this a sustainable long-term approach, or am I setting myself up for a difficult transition later? Any personal experiences with similar setups would be greatly appreciated!

What’s your main motivation for going hybrid? Have you calculated if the savings will actually make it worth the extra complexity?
Using AWS services in a hybrid fashion can work well. Just be prepared for authentication complexities; IAM Roles Anywhere is a good approach. For S3, if you're pulling lots of data, keep an eye on those egress fees. If it's mostly for user uploads, consider using CloudFront to help with costs. And since you’d be accessing AWS over the public internet, think about investing in Direct Connect for better reliability and latency.
Many of our clients have successfully adopted this approach. They find that the savings from cheaper infrastructure outside AWS can offset any increased egress costs. It’s definitely feasible!
If you’re set on a hybrid model, consider alternatives for some AWS services. For example, use Backblaze instead of S3 or Kafka instead of SQS. Sure, AWS services are convenient, but trying to piece everything together can be a headache if you want to maintain flexibility with your compute resources.
One major concern with a hybrid setup like this could be egress costs and latency. Managing multiple providers means dealing with different CI/CD tools, which can be a hassle. Plus, permissions can get tricky; for instance, using AWS's EKS IRSA can be complex if you’re working cross-provider. I also wonder if you're using Fargate for long-running pods because that can get pretty pricey, especially compared to EC2.
Fargate does have savings plans, but generally, for long-running tasks, EC2 tends to be more cost-effective. It definitely adds overhead to manage AMIs and scaling, so keep that in mind!
I've definitely used Fargate for 24/7 apps before, but costs do add up fast compared to straight EC2 instances.
Totally get your point! Mixing and matching feels appealing, but sometimes it's not as straightforward as it seems. Balancing managed services with personal control can be tough.
