Taxonomy of attribute categories used to classify comparison data for Azure vs Oracle Cloud.
Which cloud is better for AI and machine learning?
Azure significantly leads with 180+ AI/ML services including Azure OpenAI, Azure Cognitive Services, and AutoML capabilities. Oracle Cloud offers 65+ services focused on database-adjacent analytics. Azure's advantage is its integration with OpenAI models and broader data science tools. Unless you're Oracle-dependent, Azure is the clear winner for AI/ML workloads.
Oracle Cloud has lower starting prices for compute instances ($20-30/month vs Azure $25-35/month) and generous free tier offerings, including 1GB free daily egress. However, total cost depends on workload type. For mixed workloads, Azure's 3-year reserved instances (72% discount) often become cheaper long-term. Oracle wins for pure database workloads; Azure wins for variable multi-service deployments.
Can I use Oracle Cloud with non-Oracle databases?
Yes. Oracle Cloud supports MySQL, PostgreSQL, and third-party databases, but Oracle's cloud is architecturally optimized for Oracle Database workloads. Non-Oracle users experience 15-25% performance degradation compared to native Oracle optimization. If not using Oracle databases, Azure or AWS are typically better choices architecturally.
Azure leads with 60+ global regions vs Oracle's 47 regions. This provides lower latency in most geographic areas and better disaster recovery options. Azure has stronger presence in Europe and Asia-Pacific, while Oracle has focused investments in major enterprise hubs. For global enterprises, Azure's coverage is more comprehensive.
Oracle Cloud is purpose-built for Oracle ERP systems (PeopleSoft, JD Edwards, E-Business Suite) with 25% performance optimization and automated administration. Azure supports these via integration but without native optimization. If you run Oracle ERP, OCI is mandatory for best performance. For SAP, Workday, or other ERPs, both clouds work equally well.
