Amazon S3	Uploading and downloading objects Setting bucket policies and ACLs Configuring lifecycle rules Setting up static website hosting
Amazon EBS	Creating snapshots Resizing volumes Modifying volume type Attaching/detaching volumes from EC2 instances
Amazon EFS	Mounting file systems to EC2 instances Managing access points Configuring backup policies Monitoring performance and usage
Amazon FSx	Creating and managing file shares Setting up data deduplication (for Windows File Server) Configuring data compression (for Lustre) Managing backups
AWS Storage Gateway	Creating and managing volumes or tapes Configuring caching settings Managing file shares (for File Gateway) Monitoring gateway health and performance

Best practices for getting started

As you begin your journey with AWS Storage as a Service, keep these best practices in mind:

1. Start small and scale: Begin with a small, non-critical workload to familiarize yourself with the services before migrating larger datasets.
2. Use AWS CLI and SDKs: Leverage these tools for automation and programmatic access to your storage resources.
3. Implement proper tagging: Use tags to organize and track your resources from the beginning.
4. Monitor your usage: Set up AWS CloudWatch to monitor your storage usage and performance metrics.
5. Secure your resources: Implement the principle of least privilege using IAM roles and policies.
6. Leverage AWS documentation: AWS provides extensive documentation and tutorials for each service.
7. Consider AWS training: AWS offers free digital training and paid certification programs to deepen your knowledge.

“When we first started with AWS Storage as a Service, we made sure to thoroughly test each service in a sandbox environment before deploying to production. This approach allowed us to understand the nuances of each service and optimize our configurations without risking our live data.” – Mark Rodriguez, DevOps Lead at a cloud-native startup

Common pitfalls to avoid

As you get started with AWS Storage as a Service, be aware of these common mistakes:

• Overlooking security: Don’t leave S3 buckets publicly accessible or EBS volumes unencrypted.
• Ignoring costs: Monitor your usage and set up billing alerts to avoid unexpected charges.
• Neglecting backups: Even though AWS services are highly durable, always implement a backup strategy.
• Over-provisioning: Start with what you need and scale up, rather than over-provisioning from the beginning.
• Forgetting about data transfer costs: Be aware of data transfer costs, especially when moving data between regions or out of AWS.

By following these guidelines and best practices, you’ll be well on your way to effectively leveraging AWS Storage as a Service for your organization’s needs.
