The short version

  • Each has a real cost: CosmosDB autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used; DigitalOcean data transfer overage charged at $0.01 per GiB beyond included allowances
  • They diverge on capability: CosmosDB covers Global Distribution, DigitalOcean covers Droplets (VPS).
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CosmosDB

  • Autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used
  • Provisioned throughput is charged in every region the account is replicated to, so multi region accounts multiply the RU bill
  • Storage charges cover data, indexes and backups in each replicated region
  • Egress out of Azure and between regions is charged, though ingress is free
  • The free allowance is one account per Azure subscription, limited to 1,000 RU/s and 25 GB
  • RU/s rates vary by region and are only shown through the pricing calculator rather than a flat published rate

DigitalOcean

  • Data transfer overage charged at $0.01 per GiB beyond included allowances
  • Free tier includes only 3 static sites; additional static sites require paid upgrade
  • Container registry free tier capped at 500 MiB storage; exceeding requires paid tier
  • Functions free tier allows 90,000 GiB-seconds monthly; overages billed on usage basis
  • GPU Droplets require minimum monthly commitment for lower hourly rates; on-demand significantly more expensive

Answered from the vendors’ own pages

CosmosDB: Is there a free tier for Azure Cosmos DB?

Yes, Cosmos DB offers a free tier with 1,000 RU/s of throughput and 25 GB of storage per month for the lifetime of the account, available to new accounts.

DigitalOcean: How much does a DigitalOcean Droplet cost?

The cheapest Basic Droplet is $4.00 per month, or $0.00595 per hour, and includes 1 vCPU, 512 MiB of memory, 10 GiB of SSD and 500 GiB of transfer. The next step up is $6.00 per month with 1 GiB of memory, 25 GiB of SSD and 1,000 GiB of transfer.

Source
CosmosDB: How is Cosmos DB priced after the free tier?

Cosmos DB uses three billing models: provisioned throughput billed per request unit per second, vCore pricing for certain APIs, or serverless consumption pricing where you pay only for requests processed. Reserved capacity offers 20% discount for one year or 30% for three years.

DigitalOcean: How is DigitalOcean billed?

Droplets are billed hourly as well as monthly, and DigitalOcean states that Bundled Plan and v5 Droplets are billed on a per second basis with a 60 second minimum charge.

CosmosDB: Can I change my pricing model after choosing one?

No. Once you select a compute pricing model and API, they cannot be changed. This choice is permanent for that database.

Source
DigitalOcean: What does the cheapest DigitalOcean plan include?

At $4.00 per month you get a single vCPU, 512 MiB of memory, 10 GiB of SSD storage and 500 GiB of outbound transfer. That is the smallest Basic Droplet DigitalOcean sells.

Source
CosmosDB: Is there a trial period for Cosmos DB beyond the free tier?

Azure offers a 30-day free trial account for all Azure services. Additionally, Azure AI customers may be eligible for a 90-day free Cosmos DB subscription through the Azure AI Advantage program.
