Cost estimates

Assumptions

The estimate below assumes:

• Tenant has 1 team containing 100 users.
• Administrator opts to create a custom domain name and obtain an SSL certificate for the site.
  • When purchased through Azure, this is typically ~$12 for a domain name, and $75/year for the SSL certificate.
  • If you choose to use Azure Front Door, that adds a monthly cost of $46 (for 2 routing rules + minimal bandwidth consumption).

The template defaults to using Azure Front Door, to reduce the cost of trying out and experimenting with the template, rather than requiring you to get a custom domain outright. For instance, you can run your instance for a few days, then turn off the services, and only pay for your actual Azure usage when the services were on.

Estimated load

Data storage: Up to 1 GB usage of azure table storage.

Table data operations (monthly):

• Storage is called to add new idea.
  • 1 team member adds 3 ideas per day = 90 ideas per month = 90 write calls to storage.
  • Total number of write calls for TeamIdeaEntity table = 100 users * 90 ideas = 9000 calls.
• Storage is called to update existing idea.
  • 1 team member updates 1 idea per day = 30 ideas per month = 30 write calls to storage.
  • Total number of write calls for TeamIdeaEntity table = 100 users * 30 ideas = 3000 calls.
• Storage is called to delete existing idea.
  • 1 team member deletes 10 ideas per month = 10 delete calls to storage.
  • Total number of delete calls for TeamIdeaEntity table = 100 users * 10 ideas = 1000 calls.
• Storage is called to update total votes count for idea.
  • 1 team member upvotes/downvotes 20 idea per day = 600 per month = 600 write calls to storage.
  • Total number of write calls for TeamIdeaEntity table = 100 users * 600 ideas = 60000 calls.
• Storage is called to set up team preferences.
  • 1 team updates preference settings 2 times a month = 2 per month = 2 write calls to storage.
  • Total number of write calls for TeamPreferenceEntity table = 1 team * 2 calls for update/insert = 2 calls.
• Storage is called to add idea to user's private list.
  • 1 team member adds 1 idea to private list per day = 30 ideas per month = 30 write calls to storage.
  • Total number of write calls for UserPrivatePostEntity table = 100 users * 30 ideas = 3000 calls.
• Storage is called to delete idea to user's private list.
  • 1 team member deletes 1 idea from private list per day = 30 ideas per month = 30 delete calls to storage.
  • Total number of delete calls for UserPrivatePostEntity table = 100 users * 30 ideas = 3000 calls.
• Storage is called to retrieve user's private list.
  • 1 team member views private list 10 times per day = 300 times per month = 300 read calls to storage.
  • Total number of read calls for UserPrivatePostEntity table = 100 users * 300 ideas = 30000 calls.
• Storage is called to fetch team preferences.
  • For updating preferences, existing record is fetched = 2 per month = 2 read calls to storage.
  • Total number of read calls for TeamPreferenceEntity table = 1 team * 2 calls = 2 calls.
• Azure Search service reads data for indexing.
  • For instantly reflecting data in Azure Search service, indexer is triggered manually whenever change happens to database
• Considering all write calls mentioned previously:
  • Total number of read calls for TeamIdeaEntity table = 73000 write calls = 73000 read calls.
  • Total estimated read calls: 103,002
  • Total estimated write calls: 79,002
  • Total storage calls: 182,004

Estimated cost

IMPORTANT:

• This is only an estimate, based on the assumptions above. Your actual costs may vary.
• Prices were taken from the Pricing on 09 June 2020, for the West US 2 region.

SKU recommendations

The recommended SKU for a production environment is:

• App Service: Standard (S1)
• Azure Search: Basic (The Azure Search service cannot be upgraded once it is provisioned, so select a tier that will meet your anticipated needs).
