The Right Formula to Estimate Budget for Backend Infrastructure Needed for a Mobile App

• 1. Determine expected user base and usage patterns:

  Estimate the number of active users and their interaction with the app. Calculate the average number of actions (e.g., uploads) each user performs monthly.

• 2. Calculate data storage requirements:

  Estimate the total data generated by user actions. Choose a cloud storage service and determine the cost per GB. Multiply the total data by the cost per GB to find the monthly storage cost.

• 3. Assess compute resource needs:

  Determine the compute resources required to handle user interactions. Calculate the total compute hours needed per month and multiply by the cost per compute unit to find the monthly compute cost.

• 4. Estimate data transfer costs:

  Calculate the total data transfer involved in user actions. Determine the cost per GB for data transfer and multiply by the total data transfer to find the monthly cost.

• 5. Account for additional services:

  Include costs for database services, monitoring, backups, and other necessary infrastructure components. Estimate a monthly cost for these additional services.

• 6. Sum up the monthly costs:

  Add the costs from storage, compute, data transfer, and additional services to get the total monthly backend infrastructure budget.

• 7. Calculate the annual budget:

  Multiply the total monthly budget by 12 to estimate the annual budget for the backend infrastructure.

An Illustrative Example You Can Use

Replace the bold numbers with your own data to get a result for your project.

To help you better understand, let’s take a fictional example. Imagine you are developing a mobile app that allows users to upload and share photos. To estimate the budget for the backend infrastructure, you first need to determine the expected user base and usage patterns.

Let's assume you anticipate 100,000 active users in the first year, with each user uploading an average of 10 photos per month. This results in 1,000,000 photo uploads per month. If each photo is approximately 2 MB, you will need to handle 2,000 GB (or 2 TB) of data storage per month.

For storage, you might choose a cloud service like Amazon S3, which costs around $0.023 per GB for the first 50 TB per month. Therefore, the monthly storage cost would be 2,000 GB * $0.023 = $46.

Next, consider the compute resources needed to handle user requests and process uploads. Assume each user interaction requires 0.1 compute units, and each compute unit costs $0.05 per hour. With 100,000 users interacting with the app for an average of 10 minutes per day, you have 100,000 * (10/60) = 16,667 compute hours per day, or 500,010 compute hours per month. The monthly compute cost would be 500,010 * 0.1 * $0.05 = $2,500.

Additionally, you need to account for data transfer costs. If each photo upload and download involves 2 MB of data transfer, and assuming 50% of the photos are downloaded once, the total data transfer is 3,000 GB per month. With a data transfer cost of $0.09 per GB, this results in a monthly cost of 3,000 * $0.09 = $270.

Finally, consider additional costs such as database services, monitoring, and backups, which might add another $500 per month. Summing these costs gives a total monthly backend infrastructure budget of $46 (storage) + $2,500 (compute) + $270 (data transfer) + $500 (additional services) = $3,316.

Therefore, the estimated annual budget for the backend infrastructure would be $3,316 * 12 = $39,792. This detailed estimation provides a comprehensive view of the costs involved in supporting the backend infrastructure for your mobile app.
