AWS S3 FTP is a game-changer for secure file transfers. It allows you to transfer files to and from Amazon S3 using the File Transfer Protocol (FTP) protocol.
With AWS S3 FTP, you can easily transfer large files without worrying about security risks. This is because S3 is a highly secure service that uses SSL/TLS encryption to protect data in transit.
This means you can transfer files to and from S3 without exposing your sensitive data to the internet. AWS S3 FTP also supports both active and passive modes, making it compatible with most FTP clients.
Using AWS S3 FTP, you can transfer files up to 5 TB in size, making it ideal for large-scale file transfers.
Cloud Storage
Amazon's Simple Storage Service (S3) is a block-storage system that can store petabytes of data at a very low cost of $0.02 per month per GB.
Data availability is a top priority, and S3 shines with automatic replication of saved data to a minimum of three segregated data centers, offering eleven 9's of durability.
Files can get cluttered on FTP servers, but S3's automatic data retention policies can help keep things organized without any additional cost.
Files can be reclassified and moved to Amazon's tape storage equivalent after reaching a user-defined age, bringing the data storage cost down to $0.004 per month per GB.
S3 also allows for automatic deletion of files after reaching a different user-defined age beyond the tape-backup age.
File uploads can trigger events, such as running custom code against the newly uploaded file, or putting a message on a queue for further processing.
Benefits and Features
AWS S3 FTP offers a fully managed, serverless File Transfer Workflow service that makes it simple to set up, execute, automate, and monitor file processing. You can utilize native AWS services for processing, analytics, reporting, auditing, and archiving with your data safely stored in Amazon S3.
There are no upfront costs, and you pay only for the use of the service. This means you can take advantage of AWS S3 FTP without breaking the bank.
AWS provides a wide-variety of products in the Infrastructure, Platform, and Software-as-a-Service (IaaS, PaaS, and SaaS) spaces, including a storage service, S3, and Availability Zones (AZs). Each AZ is a physical data center where all the servers live, connected to each other with a private fiber-optic network to minimize latency.
The resiliency of each region in AWS comes from how Amazon selects the physical location of the AZs, diversifying them as much as possible in terms of flood plains and power grid attachment. This minimizes single points of failure within a region.
Couchdrop with S3 uses encrypted transfers (SFTP, FTPS) and supports AWS IAM roles for secure access management.

Features of
Amazon Web Services (AWS) is a powerhouse when it comes to providing a robust infrastructure for your team's devops environment. One of the biggest features that AWS provides is inherent resiliency in its services, specifically in storage service S3 and Availability Zones (AZs).
AWS' infrastructure is divided into regions, which are further divided into Availability Zones. Each AZ is essentially a physical data center where all the servers live, connected to each other with a private fiber-optic network to minimize latency between locations.
The resiliency of each region in AWS comes from how Amazon selects the physical location of the AZs, diversifying them as much as possible in terms of flood plains and power grids to minimize single points of failure within a region.
High-Availability architecture at AWS suggests spreading your servers across multiple AZs with a managed elastic load balancer directing traffic to healthy AZs. If an AZ goes down, the resiliency of the region lives on, and the load balancer will shift traffic to the remaining healthy AZs.
AWS offers a wide variety of products in the Infrastructure, Platform, and Software-as-a-Service (IaaS, PaaS, and SaaS) spaces. Here are some of the key features:
- Resilient storage service S3
- Availability Zones (AZs) for high-availability architecture
- Managed elastic load balancer for traffic redirection
- Support for multiple protocols, including SFTP, FTPS, and FTP
