Google Cloud's compute services focus on innovation and scalability:
Compute Engine: Google Cloud's virtual machine service, offering a range of machine types and customisation options.
Cloud Functions: Google Cloud's serverless compute service, similar to AWS Lambda and Azure Functions. Supports multiple programming languages and integrates with other Google Cloud services.
Google Kubernetes Engine (GKE): Google Cloud's managed Kubernetes service, built on Google's experience with container orchestration. GKE offers advanced features and scalability.
Cloud Run: A serverless compute platform that allows you to run containers without managing infrastructure. Supports HTTP requests and event-driven applications.
App Engine: A PaaS offering for building and deploying web applications and mobile backends.
2. Storage Solutions Comparison
Cloud storage is essential for storing data and ensuring its availability, durability, and security.
AWS Storage Solutions
Amazon S3 (Simple Storage Service): Object storage for storing and retrieving any amount of data. Offers high durability, scalability, and security.
Amazon EBS (Elastic Block Storage): Block storage for use with EC2 instances. Provides persistent storage for operating systems, applications, and data.
Amazon EFS (Elastic File System): A fully managed network file system for use with EC2 instances. Allows multiple instances to access the same file system simultaneously.
Amazon Glacier: Low-cost archival storage for infrequently accessed data.
AWS Storage Gateway: Connects on-premises applications to AWS storage services.
Azure Storage Solutions
Azure Blob Storage: Object storage for storing unstructured data, such as text, images, and videos.
Azure Disk Storage: Block storage for use with Azure Virtual Machines. Provides persistent storage for operating systems, applications, and data.
Azure Files: A fully managed file share service that allows you to access files from anywhere.
Azure Archive Storage: Low-cost storage for rarely accessed data.
Azure Data Lake Storage: Scalable and secure data lake for big data analytics.
Google Cloud Storage Solutions
Cloud Storage: Object storage for storing and retrieving any amount of data. Offers high durability, scalability, and security.
Persistent Disk: Block storage for use with Compute Engine instances. Provides persistent storage for operating systems, applications, and data.
Cloud Filestore: A fully managed network file system for use with Compute Engine instances.
Cloud Storage Nearline and Coldline: Low-cost storage options for infrequently accessed data.
3. Database Offerings Comparison
Cloud databases provide scalable, reliable, and managed database services.
AWS Database Offerings
Amazon RDS (Relational Database Service): Supports various database engines, including MySQL, PostgreSQL, Oracle, SQL Server, and MariaDB.
Amazon Aurora: A MySQL- and PostgreSQL-compatible relational database built for the cloud.
Amazon DynamoDB: A NoSQL database service that provides fast and predictable performance at any scale.
Amazon Redshift: A data warehouse service for large-scale data analytics.
Amazon DocumentDB: A fully managed NoSQL document database service that is compatible with MongoDB.
Azure Database Offerings
Azure SQL Database: A fully managed relational database service based on SQL Server.
Azure Database for MySQL: A managed MySQL database service.
Azure Database for PostgreSQL: A managed PostgreSQL database service.
Azure Cosmos DB: A globally distributed, multi-model database service that supports NoSQL and relational data.
Azure Synapse Analytics: A data warehouse service for large-scale data analytics.
Google Cloud Database Offerings
Cloud SQL: Supports various database engines, including MySQL, PostgreSQL, and SQL Server.
Cloud Spanner: A globally distributed, scalable, and strongly consistent database service.
Cloud Datastore: A NoSQL database service for web and mobile applications.
BigQuery: A data warehouse service for large-scale data analytics.
Cloud Memorystore: In-memory data store service for caching and real-time data processing.
4. Pricing Structures and Cost Analysis
Understanding the pricing structures of each platform is crucial for cost optimisation.
AWS Pricing: AWS offers a variety of pricing models, including pay-as-you-go, reserved instances, spot instances, and savings plans. Frequently asked questions can help clarify specific pricing questions.
Azure Pricing: Azure also offers pay-as-you-go, reserved instances, and spot virtual machines. Azure Hybrid Benefit allows you to use on-premises Windows Server licences in the cloud.
Google Cloud Pricing: Google Cloud offers pay-as-you-go, sustained use discounts, committed use discounts, and preemptible VMs. Google Cloud also offers custom machine types for precise resource allocation.
Each provider has a pricing calculator to help estimate costs based on your specific needs. It's essential to carefully analyse your workload requirements and choose the most cost-effective pricing model. Factors like instance types, storage capacity, data transfer, and usage patterns all impact the final cost. Consider using cost management tools to monitor and optimise your cloud spending.

Google Cloud Security: Google Cloud offers a range of security services, including Cloud IAM, encryption, network security, and compliance certifications. Google Cloud Security Command Center provides visibility into your security posture and helps you identify and remediate threats.
All three providers comply with various industry standards and regulations, such as ISO 27001, SOC 2, and HIPAA. It's essential to review the compliance certifications of each platform and ensure that they meet your organisation's specific requirements. A robust security strategy should include data encryption, access control, network segmentation, and regular security assessments.
