AWS → GCP
To migrate your enterprise-level SaaS application from AWS to Google Cloud, you’ll need to find equivalent Google Cloud services for the AWS services you currently use, while ensuring your architecture remains compatible. Here's a service-by-service breakdown for smooth development:
1. AWS EKS (Elastic Kubernetes Service) → Google Kubernetes Engine (GKE)
Google Kubernetes Engine (GKE) is Google Cloud’s equivalent to AWS EKS. Both manage Kubernetes clusters, offering similar features like autoscaling, security, and networking.
- Migration Notes: Kubernetes manifests and Helm charts will be reusable with minimal modification, but you’ll need to handle network and security configurations specific to Google Cloud.
2. AWS RDS (Relational Database Service) → Cloud SQL / Cloud Spanner
- Cloud SQL: Supports MySQL, PostgreSQL, and SQL Server, making it a direct equivalent for most RDS instances.
- Cloud Spanner: If you need horizontally scalable, globally distributed databases with strong consistency, consider Cloud Spanner.
- Migration Notes: Database migration tools like Database Migration Service can help with the data migration, ensuring minimal downtime and compatibility.
3. AWS EFS (Elastic File System) → Filestore
Google Cloud Filestore is a fully managed NFS (Network File System) service similar to AWS EFS.
- Migration Notes: Ensure your applications are configured to use the Filestore APIs and access paths properly. Performance tiers and network configuration will need review for alignment with your AWS EFS setup.
4. AWS S3 (Simple Storage Service) → Google Cloud Storage
Google Cloud Storage is a direct equivalent to AWS S3 for object storage, supporting multiple classes of storage with similar durability and availability guarantees.
- Migration Notes: Google Cloud’s storage APIs differ slightly, so you may need to refactor your code to accommodate the differences. However, bucket management and object lifecycle policies are similar.
5. AWS Lambda (Serverless Compute) → Google Cloud Functions / Cloud Run
- Google Cloud Functions: Equivalent to AWS Lambda for small, event-driven serverless tasks.
- Cloud Run: If you need to run containerized microservices, Cloud Run (based on Knative) is a good choice for scaling container workloads.
- Migration Notes: Code migration is generally straightforward, though GCP uses slightly different event triggers and permission models.
6. AWS Parameter Store → Secret Manager / Cloud Key Management Service (KMS)
- Secret Manager: For storing secrets such as passwords, API keys, and tokens.
- Cloud KMS: For managing encryption keys and ensuring data security.
- Migration Notes: Similar management principles apply, but authentication and access policies will need revision to comply with Google Cloud's identity model.
7. AWS SES (Simple Email Service) → SendGrid / Mailgun (Third-party service)
Google Cloud doesn't have a native email service comparable to SES, so you can leverage third-party services like SendGrid or Mailgun, which integrate well with Google Cloud.
- Migration Notes: Integration through APIs will require code changes, but the overall functionality will remain similar.
8. AWS CloudWatch → Google Cloud Monitoring (formerly Stackdriver)
Google Cloud Monitoring is the equivalent of AWS CloudWatch, providing observability, logging, and alerting for your infrastructure and applications.
- Migration Notes: If you are heavily using AWS CloudWatch Logs, consider migrating to Google Cloud Logging to keep a similar flow of data.
Additional Considerations:
- IAM and Security: AWS Identity and Access Management (IAM) maps well to Google Cloud IAM, but you'll need to refactor policies and roles.
- Networking: Google Cloud’s VPC is similar to AWS VPC, but you'll need to translate networking configurations (firewalls, routing, etc.) and possibly update load balancing setups, using Google Cloud Load Balancer in place of AWS Elastic Load Balancing (ELB).
Tools for Migration:
- Google’s Database Migration Service: To migrate RDS databases to Cloud SQL.
- Migrate for Compute Engine: For VM migrations if you use EC2 instances.
- Velostrata: For handling live migrations of workloads.
