Alibaba Cloud MaxCompute vs IBM Db2

Alibaba Cloud MaxCompute is a web-accessible, cloud-deployed data platform with separate storage and compute. It supports data lakes, streaming ingestion, and in-database machine learning. Standard computing resources cost $22 a month on subscription, with a minimum purchase of 50 CUs. Multi-zone HA computing resources cost $28.60 a month on subscription and provide high-availability compute across multiple availability zones. For elastic capacity, Elastically reserved CUs are listed at $0.05 a month, billed hourly, with scheduled scaling and pay-as-you-go billing. Auto-elastic CUs are listed at $0.06 a month, billed hourly, with usage monitored per second, automatic scaling, and charges based on resources consumed. The pricing model is paid, with a starting pricing note of $0.05. These options separate fixed subscription capacity from elastic resource usage, while the platform’s storage and compute separation supports data workloads that need independently provisioned resources.
