# 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.
