Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
Azure Functions pricing
Event-driven compute on demand
- No upfront cost
- No termination fees
- Per-second billing
Azure Functions provide a serverless development experience supporting a robust set of event triggers and data bindings.
US government entities are eligible to purchase Azure Government services from a licensing solution provider with no upfront financial commitment, or directly through a pay-as-you-go online subscription.
Important—The price in R$ is merely a reference; this is an international transaction and the final price is subject to exchange rates and the inclusion of IOF taxes. An eNF will not be issued.
Azure Germany is available to customers and partners who have already purchased this, doing business in the European Union (EU), the European Free Trade Association (EFTA), and in the United Kingdom (UK). It provides data residency in Germany with additional levels of control and data protection. You can also sign up for a free Azure trial.

Azure Functions pricing
Azure Functions consumption plan is billed based on per-second resource consumption and executions. Consumption plan pricing includes a monthly free grant of 1 million requests and 400,000 GB-s of resource consumption per month per subscription in pay-as-you-go pricing across all function apps in that subscription. Azure Functions Premium plan provides enhanced performance and is billed on a per second basis based on the number of vCPU-s and GB-s your Premium Functions consume. Customers can also run Functions within their App Service plan at regular App Service plan rates.
| Meter | Price | Free Grant (Per Month) |
|---|---|---|
| Execution Time* | $-/GB-s | 400,000 GB-s |
| Total Executions* | $- per million executions | 1 million executions |
Note—A storage account is created by default with each Functions app. The storage account is not included in the free grant. Standard storage rates and networking rates charged separately as applicable.

Pricing details
Executions
Functions are billed based on total number of requested executions each month for all functions. Executions are counted each time a function is executed in response to an event, triggered by a binding. The first million executions are included free each month.
Resource consumption
Functions are billed based on observed resource consumption measured in gigabyte seconds (GB-s). Observed resource consumption is calculated by multiplying average memory size in gigabytes by the time in milliseconds it takes to execute the function. Memory used by a function is measured by rounding up to the nearest 128 MB, up to the maximum memory size of 1,536 MB, with execution time calculated by rounding up to the nearest 1 ms. The minimum execution time and memory for a single function execution is 100 ms and 128 mb respectively. Functions pricing includes a monthly free grant of 400,000 GB-s.
Azure Functions can be used with Azure IoT Edge at no charge.
Premium plan
Azure Functions Premium plan provides the same features and scaling mechanism used on the Consumption plan (based on number of events) with no cold start, enhanced performance and VNET access. Azure Functions Premium plan is billed based on the vCPU and memory that your functions consume.
| Meter | Price |
|---|---|
| vCPU duration | vCPU: $- |
| Memory duration | Memory: $- |
Functions Proxies
The same pricing applies to Functions Proxies. A proxy is a function that is triggered by an HTTP request. Memory used by a proxy is less than 128 MB. Proxy execution time is the round-trip time (request to response), because the proxy needs to stay up to keep the HTTP connection alive. If a proxy triggers a function, the function execution and memory usage is counted separately.
Pricing example
A function with observed memory consumption of 512 MB executes 3,000,000 times during the month and has an execution duration of one second. Monthly billing would be calculated as follows:
