Panda Edge pricing

PandaEdge functions are priced based on two main components:

1. Memory allocation and execution duration

2. Number of invocations

Memory Pricing

Memory is priced based on GB-seconds with different tiers:

Memory Allocation	Price Multiplier	Example
≤ 256MB	1.0x (base price)	Default tier
≤ 512MB	1.2x	20% premium
≤ 1024MB	1.5x	50% premium
≤ 2048MB	2.0x	100% premium
> 2048MB	3.0x	200% premium

Base memory price: $0.0000167 per GB-second

Invocation Pricing

Each function invocation is charged at a flat rate:

• $0.0000002 per invocation

Cost Calculation

Your hourly cost is calculated as:

Memory Cost = GB * seconds * invocations * $0.0000167 * tier_multiplier
Invocation Cost = invocations * $0.0000002
Total Cost = Memory Cost + Invocation Cost

Example Calculations

Example 1: Basic Function (256MB)

• Memory: 256MB (0.25GB)

• Duration: 0.012 seconds

• Invocations: 14 per hour

Memory Cost = 0.25GB * 0.012s * 14 * $0.0000167 * 1.0
            = $0.0000007014

Invocation Cost = 14 * $0.0000002
                = $0.0000028

Total Cost = $0.0000035014 per hour

Example 2: High Volume API (256MB)

• Memory: 256MB (0.25GB)

• Duration: 0.1 seconds (minimum)

• Invocations: 100,000,000 per month (~138,889 per hour)

Monthly Memory Cost = 0.25GB * 0.1s * 100,000,000 * $0.0000167 * 1.0
                   = $41.75

Monthly Invocation Cost = 100,000,000 * $0.0000002
                       = $20.00

Total Monthly Cost = $61.75

Average Hourly Cost = $61.75 / (30 * 24)
                   = $0.0858 per hour

Example 3: High Volume Processing (512MB)

• Memory: 512MB (0.5GB)

• Duration: 0.5 seconds

• Invocations: 100,000,000 per month (~138,889 per hour)

Monthly Memory Cost = 0.5GB * 0.5s * 100,000,000 * $0.0000167 * 1.2
                   = $501.00

Monthly Invocation Cost = 100,000,000 * $0.0000002
                       = $20.00

Total Monthly Cost = $521.00

Average Hourly Cost = $521.00 / (30 * 24)
                   = $0.7236 per hour

Example 4: Data Processing (2GB)

• Memory: 2048MB (2GB)

• Duration: 2 seconds

• Invocations: 10 per hour

Memory Cost = 2GB * 2s * 10 * $0.0000167 * 2.0
            = $0.001336

Invocation Cost = 10 * $0.0000002
                = $0.000002

Total Cost = $0.001338 per hour

Important Notes

1. System Limits:

   • Default limit: 1000 invocations per minute

   • Maximum memory allocation: 2048MB (2GB)

   • Memory allocations beyond 2048MB are not allowed

   • Contact support for custom limits

2. High Volume Considerations:

   • 100M invocations/month ≈ 138,889 invocations/hour

   • Memory allocation significantly impacts cost at high volumes

   • Optimize execution duration for cost efficiency

   • Consider memory tier pricing multipliers

3. Memory Allocation:

   • Default is 256MB if not specified

   • Choose the right memory tier based on your function's needs (up to 2048MB)

   • Higher tiers cost more but might execute faster

   • At high volumes, even small memory/duration optimizations matter

4. Cost Optimization Tips:

   • Keep functions small and focused

   • Minimize execution time

   • Choose appropriate memory allocation

   • Consider cold starts in your architecture

   • For high volume, optimize memory and duration first

5. Billing Frequency:

   • Costs are calculated hourly

   • Each hour's metrics are collected and stored independently

   • You can monitor costs through the dashboard

Usage Tiers

1. Low Volume (1,000 invocations/month):

   • 256MB, 0.1s duration

   • Monthly cost: ~$0.0006

   • Good for development/testing

2. Medium Volume (1,000,000 invocations/month):

   • 256MB, 0.1s duration

   • Monthly cost: ~$0.62

   • Typical for small production apps

3. High Volume (100,000,000 invocations/month):

   • 256MB, 0.1s duration

   • Monthly cost: ~$61.75

   • Enterprise-level usage

4. Cost Scaling:

   • Costs scale linearly with invocations

   • Memory tier multipliers apply to memory costs only

   • Duration optimization becomes critical at high volumes

Monitoring and Cost Control

1. Real-time Metrics:

   • Function invocations

   • Execution duration

   • Memory usage

   • Hourly costs

2. Cost Management:

   • Set budget alerts

   • Monitor usage patterns

   • Optimize based on metrics

   • Scale efficiently

3. High Volume Tips:

   • Monitor average duration closely

   • Consider memory vs duration tradeoffs

   • Set up alerts for unusual patterns
