Choosing between self-hosted and cloud solutions is not binary. The best approach depends on your specific requirements for cost, control, compliance, and operational capacity.
Self-hosting makes sense when you have sensitive data requiring strict access controls, predictable high-volume workloads where cloud costs would escalate, regulatory requirements mandating data residency, or existing infrastructure that can be leveraged.
Cloud services excel when you need rapid scaling for unpredictable workloads, prefer operational simplicity over control, have distributed teams requiring global access, or want to minimize upfront capital expenditure.
Most businesses benefit from a hybrid approach: self-hosting core business systems and data while using cloud services for collaboration, communication, and burst capacity. The key is understanding your actual requirements and total cost of ownership for each option.
