Amazon S3 Share Folder and Files

Share Amazon S3 folders over the Internet and share files online from AWS data centers. Maintain data privacy and control. Turn S3 into your file sharing center with colleagues and business partners.

Unleash the File Sharing Power of AWS S3

Amazon S3, for the most part, is known as the best cloud storage service in the market for its industry-leading scalability, data availability, security, and performance. Cloud storage is a natural fit for sharing across the Internet as compared to traditional on-premise file servers behind a corporate firewall. However, making S3 folders public may be the only default quick way to share. For those with security in mind, creating AWS IAM users for S3 file sharing sounds too complicated. You need a good solution to unleash the secure file sharing power of AWS S3. 

Share files with co-workers, customers and partners

Sending emails with several attachments was a norm over the years when it comes to sending files to co-workers or business partners. However, share a folder was never easy with email attachments. Sharing large file was impossible and got blocked by email services. With Amazon S3, it is much easier to share files and folders over the Internet since every file and folder has a default "web link" representation. AWS S3 has the building blocks for file sharing and the S3 storage by default is enterprise ready. All that we need is a solution to put-it-together into a nice easy-to-use and yet secure file sharing solution.

Use Case 1 - Files for Accountants 

Accountants works on Quickbooks and need supporting documents from clients to close the books. They create web links represent folders from AWS S3 and send the link to clients that they help with book keeping. Those who received links, with password protection can securely upload documents to their accounts, without the need of sending email attachments or uploading to Dropbox.

Use Case 2 - House Pictures

Real estate agents going out to the houses in the market and take pictures of the house on their iPhones and iPads. The pictures are uploaded to Amazon S3 as the company's centralized media folder. Graphical designers back at the head quarter use a s3 mapped drive and Photoshop to enhance those house pictures before the house is posted for sale with nice picture presentations.

Use Case 3 - Business Analytic

Company needs to share a big folder of data with external data analytic firms for data mining and business intelligence. Instead of uploading tons of data to public sharing sites, the company is using CentreStack hybrid cloud file server to link several file server folders with Amazon S3 and share big folders with external firm securely. When the project is done, the external sharing stops and data stays within the control of the company.
