The short version

  • Only Azure Functions has a free tier, so it costs nothing to try first.
  • Each has a real cost: Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that; Sysdig custom pricing requires sales contact, difficult to compare costs

Where each one falls short

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

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward

Sysdig

  • Custom pricing requires sales contact, difficult to compare costs
  • No published pricing tiers or calculator available
  • Primarily focused on cloud-native environments
  • Requires integration with existing SIEM or monitoring tools for full visibility
  • Steep learning curve for runtime security concepts

Answered from the vendors’ own pages

Azure Functions: Does Azure Functions have a free tier?

Yes, Azure Functions includes a monthly free grant of 1 million requests and 400,000 GB-seconds on the Consumption Plan, or 250,000 executions and 100,000 GB-seconds on Flex Consumption.

Source
Sysdig: How does Sysdig achieve real-time threat detection?

Sysdig uses runtime intelligence with kernel-level system visibility, capturing live system calls to detect threats at machine speed, typically within 2 seconds.

Source
Azure Functions: What is Azure Functions' pricing model?

Azure Functions uses usage-based pricing. Consumption plans charge per second of resource consumption and per execution, measured in gigabyte-seconds and rounded to the nearest 128 MB.

Source
Sysdig: What is runtime intelligence and how does it differ from configuration-based security?

Runtime intelligence reveals what is actually executing in cloud environments through kernel-level visibility, rather than relying on theoretical risks from configuration analysis alone.

Source
Azure Functions: What is the minimum execution time for Azure Functions?

The minimum execution time is 100 milliseconds on Consumption plans. Premium plans charge based on core seconds and allocated memory.

Source
Sysdig: What cloud platforms does Sysdig support?

Sysdig supports AWS, GCP, Azure, and IBM Cloud with multiple regional data centers across US, EU, and other regions.

Source
Sysdig: Does Sysdig integrate with existing security tools?

Yes, Sysdig integrates with existing SIEM and monitoring tools to provide unified security visibility across cloud infrastructure.
