SAP HANA Cloud Sizing: Choosing the Right Instance on AWS, Azure and OCI
Memory Sizing Rule
HANA is an in-memory database — instance selection is driven entirely by RAM. Rule: 2x active dataset size in RAM. 100GB active data = 256GB RAM minimum for production.
Certified Instances — 256GB HANA HA
| Cloud | Instance | On-Demand/mo | 3yr RI/mo |
|---|---|---|---|
| AWS | r6i.8xlarge x2 | $2,949 | $1,182 |
| Azure | E32s v5 x2 | $2,944 | $1,089 |
| GCP | n2-highmem-32 x2 | $3,066 | $1,381 |
| OCI | E4.Flex 32 OCPU x2 | $1,495 | $999 |
OCI delivers 256GB HANA HA at approximately 50% of AWS/Azure cost.
HA Architecture
- Primary node: active HANA serving transactions
- Secondary node: synchronous standby, 60-120 second failover
- Backint backup to object storage every 6h incremental, full weekly
Storage
Data volume: 1.5x memory. Log volume: 0.5x memory. Use premium SSD — target 500MB/s throughput, 50,000 IOPS for 256GB system.
