This is called a bridge model.įigure 1 – Overview of SaaS architecture model.īoth silo and pool models have their own pros and cons, and you must understand their trade-offs. You can also combine silo and pool per layer basis such as compute, database, network, or per microservice. The pool model, on the other hand, refers to a model where all or part of the infrastructure is shared across all of the tenants. There is no sharing construct, so you can draw clear boundaries between tenants. The silo model is a way to provision dedicated infrastructure for each tenants. It can be divided into two types of models: silos and pools. Tenant Isolation Modelįirst, let’s review the basic SaaS architecture model. In the following sections, we’ll look at design patterns you can choose to create a multi-tenant SFTP function, taking into account requirements such as tenant isolation, performance, cost, and compliance. So, what is the best way to build an SFTP server in a multi-tenant way? In a multi-tenant SaaS environment where all tenants share the same underlying infrastructure, you need robust, highly available, performant, and also cost-effective way to serve tenants requirements.

In such cases, the alternative to create an SFTP endpoint for customers can be considered.

Or, you may want to synchronize data between your SaaS application and a third-party external services like a CRM, but not all solutions support HTTP. For example, if you offer solutions like hosting a website you may want to allow customers to upload contents via SFTP, so that developers could easily introduce release pipeline automation using these protocols. These protocols are sometimes required, even if your application is constructed as web-based SaaS delivery model. Since the content is not encrypted in FTP (File Transfer Protocol) communication, you should secure connection with SSL/TLS (FTPS) or replaced with SFTP to protect customer sensitive data. SFTP/FTPS/FTP is a common standard protocol for transferring files between a server and a client. In this case, HTTP(S) is used as the protocol, but some may want to exchange data via different protocols such as SFTP due to customer requirements or technical limitations. Today, SaaS providers typically use web-based user interface (UI) to display data in a human-readable format or fill in forms to modify data. There are several ways SaaS vendors can make data accessible to customers. AWS Transfer Family allows you to quickly provide your customers with a managed, scalable SFTP endpoint and securely exchange data back and forth to Amazon S3 or EFS. You don’t need to manage servers or take care of scaling. This post explores how SaaS vendors can build secure, scalable, and cost-effective data exchange mechanisms using SFTP (SSH File Transfer Protocol) with AWS managed services.ĪWS Transfer Family securely scales your recurring business-to-business file transfers to Amazon Simple Storage Service (Amazon S3) and Amazon Elastic File System (Amazon EFS) using SFTP, FTPS, and FTP protocols. Creating secured mechanisms to achieve tenant isolation on your own is possible, but usually requires significant effort and consumes valuable time.

How to securely segregate tenant data and how to provide data access to customers will vary depending on the SaaS solution’s architecture and its requirements. Or to use EC2 instance and get node.js installed.By Hiroto Sakuraya, Partner Solutions Architect – AWSĭata security is a particularly important topic for multi-tenant software-as-a-service (SaaS) applications that handle customers’ sensitive data. We can create separate Lambda function for each operation. Can all the above operations (checksum, decrypt and decompression) be performed using Lambda function. Can Lambda function be able to reach to FTP server in DC1 which is sitting behind a firewall. I thought of using Lambda function but how will network side of things work. No agent can be installed on any of the On Premise server Only need to run the SFTP operation once on daily basis These flat files wont be accessed frequently and will be saved for audit purposes. These files will be required for 12 months and then deleted.

Store the flat files (from zip file) in AWS London region in S3. Get the zipped file from on premise server in DC!, and perform following : DEcrypting, perform check on checksum and DEcompression. Data Centre 1 cannot be reached via Public internet.īut it has a connectivity to Data Centre 2 via MPLS.ĭatacentre 2 has Direct Connect Link Set up with AWS Ireland.

I am new to AWS and looking for guidance to design a FTP solutionĪ zipped file (encrypted) plus a checksum file will be available on FTP server in Data Center 1 (once daily at around 1 am).
