Microsoft Azure vs Neon DB

• Azure starts its database pricing at $7.59/mo, whereas Neon offers a free entry point, though Neon’s storage overage cost is significantly steeper at $0.35/GB compared to Azure’s $0.08/GB.
• Memory scaling reaches 16 GB for both platforms, but Azure provides up to 250 GB of disk storage in its upper tiers, dwarfing Neon’s 50 GB limit.
• Azure’s vCPU allocation is more generous, offering up to 4 vCPU cores, while Neon caps out at 2 vCPU, reflecting their focus on serverless architecture rather than traditional provisioned hardware.
• Egress penalties remain tight across both, with Azure charging $0.09/GB and Neon at $0.10/GB for traffic exceeding bundled quotas.

Azure operates on standard provisioned hardware, which is better suited for predictable, high-IOPS workloads where you need consistent access to disk performance. Because it relies on fixed infrastructure, you are essentially paying for the idle time of the vCPU and RAM, which provides stability for long-running transactions. Neon, by contrast, uses a storage-disaggregated model common in modern cloud-native environments. This allows for rapid branching and scaling, but you pay a premium for that flexibility through higher storage overage rates. If your database size is small but your compute needs are bursty, Neon avoids the waste of paying for a full-time Azure instance, but heavy storage growth will quickly turn Neon’s lower base price into a liability.

Choosing between these two comes down to your storage growth pattern and the necessity of dedicated compute. Azure is the safer bet for applications with massive, static datasets that exceed the 50 GB threshold Neon imposes. Neon works best for development environments or small, highly dynamic applications where the ability to spin up and tear down instances outweighs the cost of per-gigabyte storage spikes.
