It offers automatic sustained use discounts, meaning you automatically get lower prices for running virtual machines for a significant portion of the month, without needing to pre-purchase RIs. Committed Use Discounts (CUDs) offer even greater savings for one- or three-year commitments. GCP also has per-second billing for many services, which can be more cost-effective for short-lived workloads. Their focus on data analytics and AI services often comes with competitive pricing for those specific use cases.
3. Security, Compliance, and Data Governance Features
Security is paramount in cloud computing. All three providers invest heavily in security, offering robust features and compliance certifications, though their approaches and strengths vary.
AWS Security
AWS operates under a shared responsibility model: AWS is responsible for the security of the cloud, while the customer is responsible for security in the cloud. AWS offers a comprehensive suite of security services, including Identity and Access Management (IAM), network security (VPC, Security Groups, Network ACLs), data encryption (KMS, S3 encryption), and compliance certifications (ISO 27001, PCI DSS, GDPR, HIPAA, IRAP for Australia). Its extensive documentation and security best practices are well-established.
Azure Security
Azure also adheres to a shared responsibility model. Leveraging Microsoft's long-standing enterprise security expertise, Azure offers strong identity and access management through Azure Active Directory, which integrates seamlessly with on-premises AD.
