Google Cloud Compute Services

Compute Engine: Google Cloud's virtual machine service, offering a range of machine types and customisation options. Known for its sustained use discounts.
Cloud Functions: Google Cloud's serverless compute offering, comparable to AWS Lambda and Azure Functions.
Cloud Run: A managed compute platform that allows you to run stateless containers via HTTP requests. Supports both container images and source code.
Google Kubernetes Engine (GKE): The original Kubernetes service, built on Google's experience with container orchestration. Provides robust features and integration with other Google Cloud services.

2. Storage Solutions Overview

Cloud storage solutions provide scalable and durable storage for data of all types.

AWS Storage Solutions

Amazon S3 (Simple Storage Service): Object storage for storing and retrieving any amount of data. Highly scalable and durable, suitable for backups, archives, and media storage.
Amazon EBS (Elastic Block Storage): Block storage volumes 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 sharing files between EC2 instances. Useful for applications that require shared storage.
Amazon Glacier: Low-cost archive storage for infrequently accessed data. Ideal for long-term backups and compliance archiving.

Azure Storage Solutions

Azure Blob Storage: Object storage similar to Amazon S3, for storing unstructured data such as images, videos, and documents.
Azure Disk Storage: Block storage for Azure Virtual Machines, providing persistent storage for operating systems and applications.
Azure Files: A fully managed file share service that can be accessed over SMB protocol. Enables file sharing between virtual machines and on-premises systems.
Azure Archive Storage: Low-cost storage for archiving data, similar to Amazon Glacier.

Google Cloud Storage Solutions

Cloud Storage: Object storage for storing and retrieving data, offering different storage classes for varying access frequencies and cost requirements.
Persistent Disk: Block storage for Compute Engine instances, providing persistent storage for operating systems and applications.
Filestore: A fully managed network file system for sharing files between Compute Engine instances.
Cloud Storage Nearline and Coldline: Low-cost storage options for infrequently accessed data, similar to Amazon Glacier and Azure Archive Storage.

3. Database Offerings

Cloud providers offer a range of database services, from relational databases to NoSQL databases.

AWS Database Offerings

Amazon RDS (Relational Database Service): Supports various database engines, including MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server. Simplifies database administration tasks.
Amazon Aurora: A MySQL and PostgreSQL-compatible relational database engine that offers improved performance and availability.
Amazon DynamoDB: A fully managed NoSQL database service that provides fast and predictable performance at any scale. Ideal for applications with high read/write throughput.
Amazon Redshift: A data warehouse service for large-scale data analysis and business intelligence.

Azure Database Offerings

Azure SQL Database: A fully managed SQL Server database service. Offers scalability, security, and high availability.
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 various NoSQL data models.
Azure Synapse Analytics: A data warehouse service for big data analytics.

Google Cloud Database Offerings

Cloud SQL: A fully managed relational database service that supports 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 analysis.

4. Pricing Models and Cost Analysis

Understanding the pricing models of each provider is crucial for managing cloud costs.

AWS Pricing: Offers various pricing models, including pay-as-you-go, reserved instances, and spot instances. Provides detailed cost management tools and calculators. AWS also offers our services to help you optimise your cloud spend.
Azure Pricing: Similar to AWS, Azure offers pay-as-you-go, reserved instances, and spot virtual machines. Provides cost management tools and Azure Cost Management + Billing.
Google Cloud Pricing: Offers sustained use discounts, committed use discounts, and preemptible virtual machines. Provides cost management tools and Cloud Billing.

Each provider has different strengths in terms of pricing. AWS is often considered competitive for established workloads, while Google Cloud's sustained use discounts can be advantageous for long-running applications. Azure's hybrid benefit can reduce costs for organisations already invested in Microsoft licences. When choosing a provider, consider what Sli offers and how it aligns with your needs.

5. Security Features and Compliance

Security is a top priority for all cloud providers.

AWS Security: Offers a wide range of security services, including IAM (Identity and Access Management), KMS (Key Management Service), and CloudTrail (audit logging). Complies with numerous industry standards and regulations.
Azure Security: Provides security services such as Azure Active Directory, Key Vault, and Azure Security Center. Complies with various industry standards and regulations.
Google Cloud Security: Offers security services such as Cloud IAM, Cloud KMS, and Cloud Audit Logging. Complies with numerous industry standards and regulations. It's important to learn more about Sli and how we can help you navigate the complexities of cloud security and compliance.

All three providers offer robust security features and compliance certifications. The specific security requirements will depend on the industry and regulatory environment.

6. Developer Tools and Ecosystem

The developer tools and ecosystem can significantly impact the ease of building and deploying applications.

AWS Developer Tools: Offers a comprehensive suite of developer tools, including SDKs, CLIs, and IDE integrations. Has a large and active community and a vast ecosystem of third-party tools and services.
