Required cluster size To tolerate two node failures and still have ≥64 vCPUs and ≥128 GB:
- 12 nodes × (8 vCPU, 16 GB) = 96 vCPUs and 192 GB
- After losing 2 nodes → remaining 80 vCPUs and 160 GB
Block Storage (approximate)
-
Using a published example of block storage from Alibaba Cloud pricing references:
- ~$11.20/mo per 100 GB (Enhanced SSD PL0 level estimate)
- For 3 TB = 30 × 100 GB → ~$336/mo
- (Actual ESSD storage pricing depends on performance tier; this is a reasonable baseline.)
Total monthly cluster cost estimate
- Compute: 12 × 170.49 ≈ $2,045.88
- Block storage: ~$336
- Estimated total: ≈ $2,380 / month
This is an approximation; actual Alibaba console pricing may vary slightly by region and storage type.

Your startup credit tiers and returns:
| Tier | Spend Threshold | Return |
|---|---|---|
| Tier 0 | Any | $200 |
| Tier 1 | Spend $1,000 in first 3 months | Get $1,000 |
| Tier 2 | Spend next $6,000 in next 3 months | Get $4,000 |
| Tier 3 | Spend next $20,000 in next 6 months | Get ~$30,000 |
| Tiers 4 & 5 | Higher amounts (beyond 12 mo spend) | Less applicable given our usage |
-
Spend: 3 × $2,380 = $7,140
-
Credits:
- Tier 0: $200
- Tier 1: $1,000 (since spend > $1,000)
-
Net at end of Q1 = $7,140 − $1,200 = $5,940
-
Spend: 3 × $2,380 = $7,140
-
Cumulative spend now ~ $14,280
-
Eligible for Tier 2: Spend in this period ≥ $6,000
- Credit: $4,000
-
Net after Q2 additional credits = $14,280 − (previous credits $1,200 + $4,000) = $9,080
-
Spend: 6 × $2,380 = $14,280
-
Cumulative spend ~ $28,560
-
Eligible for Tier 3 (spend > $20,000 in 6-mo window)
- Credit: ≈ $30,000
-
Net after Tier 3 credits = $28,560 − (credits $30,000) = −$1,440
