Reducing Your Database Hosting Costs: DigitalOcean vs. AWS vs. Azure


If you’re hosting your databases in the cloud, choosing the right cloud service provider is a significant decision to make for your long-term hosting costs. This is especially apparent in today’s world where organizations are doing whatever they can to optimize and reduce their costs.

Over the last few weeks, we have been inundated with requests from SMB customers looking to improve the ROI on their database hosting. In this article, we are going to compare three of the most popular cloud providers, AWS vs. Azure vs. DigitalOcean for their database hosting costs for MongoDB® database to help you decide which cloud is best for your business.

Comparing Cloud Instance Costs

So, which cloud provider provides the most cost-effective solution for database hosting? We compare AWS vs. Azure vs. DigitalOcean using the below instance types:

AWS EC2 instances
Azure VM instances
DigitalOcean Droplets

Since database hosting is more dependent on memory (RAM) than storage, we are going to compare various instance sizes ranging from just 1GB of RAM up to 64GB of RAM so you can see how costs vary across different application workloads.

Let’s take a look at the monthly cost (720 hours) of database hosting for standalone, on-demand, dedicated instances on AWS, Azure, and DigitalOcean. As you can see from the graph below, DigitalOcean database hosting provides significant cost savings over both AWS and Azure. Additionally, their Droplet pricing is extremely simple and easy to understand – $5/GB.

DigitalOcean Hosting FAQs

Is my database cluster still highly available?

Yes. All of our high availability options are offered in DigitalOcean, including 2 Replicas + 1 Arbiter, 3 Replicas, and custom replica set setups. DigitalOcean does not have the concept of availability zones (AZ), so we distribute the nodes across MongoDB DigitalOcean Regions – ScaleGrid different regions. For example, in the US, we distribute nodes across New York 3, New York 2, and New York 1.

Does it affect latency?

Yes, you can see an increase in latency. Ideally, we would want to see both the application and the database in the same data center. So, if you’re hosting your application in AWS or Azure and moving your database to DigitalOcean, you will see an increase in latency. However, the average latencies between AWS US-East and the DigitalOcean New York data center locations are typically only 17.4 ms round trip time.

How can I migrate?

ScaleGrid provides an Import wizard to migrate data from one cluster to another. If you have any special needs for your migration, please contact
