Amazon FSx Overview:

• Amazon FSx is a fully managed service for launching high-performance third-party file systems on AWS.
• It provides a range of options for different use cases, including Lustre, Windows File Server, NetApp ONTAP, and OpenZFS.
• Each FSx type is optimized for specific workloads and offers various features and integrations.

Amazon FSx Types:

1. Amazon FSx for Windows File Server:
   • Fully managed Windows File Server share drive supporting SMB protocol and NTFS.
   • Integrates with Microsoft Active Directory for user security.
   • Supports ACLs, user quotas, and can be mounted on Linux EC2 instances.
   • Scalable performance, ranging up to tens of gigabytes per second and millions of IOPS.
   • Offers SSD for low-latency workloads and HDD for cost-effective storage.
   • Supports Multi-AZ deployment for high availability and daily backups to Amazon S3.
2. Amazon FSx for Lustre:
   • Distributed file system for large-scale computing, ideal for machine learning and HPC.
   • Scales to hundreds of gigabytes per second, millions of IOPS, and sub-millisecond latency.
   • Offers SSD for low latency and HDD for throughput-intensive workloads.
   • Seamlessly integrates with Amazon S3 for data access and storage.
   • Supports deployment options: scratch file system for temporary storage and persistent file system for long-term storage.
   • Compatible with on-premises servers via VPN or Direct Connect.
3. Amazon FSx for NetApp ONTAP:
   • Managed NetApp ONTAP file system compatible with NFS, SMB, and iSCSI protocols.
   • Ideal for migrating workloads running on ONTAP or NAS from on-premises to AWS.
   • Broad compatibility with various operating systems and AWS services.
   • Features auto-scaling, replication, snapshots, data compression, and de-duplication.
   • Supports point-in-time instantaneous cloning for testing new workloads.
4. Amazon FSx for OpenZFS:
   • Managed OpenZFS file system compatible with NFS protocol.
   • Designed for migrating ZFS workloads to AWS.
   • Supports broad compatibility with operating systems.
   • Offers high performance with up to 1 million IOPS and low latency.
   • Features snapshots, compression, low cost, and point-in-time instantaneous cloning.

Key Points:

• Each Amazon FSx type caters to specific use cases, offering scalability, performance, and compatibility with different protocols and operating systems.
• Understanding the characteristics and features of each FSx type is crucial for selecting the right file system for specific workload requirements.

Amazon FSx offers two main file system deployment options: scratch file system and persistent file system. Let's delve into each:

Scratch File System (Amazon FSx for Lustre):

• Purpose: Temporary storage for short-term processing of data, optimized for high bursts of performance.
• Data Replication: Data is not replicated, meaning there's only one copy of the data. If the underlying server fails, data loss occurs.
• Performance: Provides exceptionally high bursts of performance, typically six times that of a persistent file system.
• Throughput: Offers high throughput, such as 200 megabytes per second per terabyte of throughput.
• Use Cases:
  • Short-term data processing where data loss is acceptable.
  • Workloads requiring optimization of costs by avoiding data replication.
• Architecture: Compute instances connect to FSx across Availability Zones (AZs), with the scratch file system having only one copy of the data.
