Performance of MFT Cloud Service (MFTCS) with File Storage Service (FSS) using a Hybrid Solution Architecture in Oracle Cloud Infrastructure (OCI) by Shub Lahiri

Executive Overview

MFT Cloud Service clusters in Oracle Cloud Infrastructure Classic (OCI-C) are provisioned with database file storage system (DBFS) for shared storage as discussed in one of our earlier blogs[1]. In Oracle Cloud Infrastructure (OCI), customers also have the option of using File Storage Service (FSS) for shared storage. FSS can be used for high throughput use cases where a large number of large files have to be processed within MFTCS. But this alternative of high performance comes at a cost of resiliency. The backup and recovery of the DBFS is automatically achieved by the backup of the database. Although, the backup and recovery recommendations for FSS are well-documented, the implementation has to be managed in a custom layer.

This blog shows the usage of FSS for shared storage in an MFTCS cluster but the same concepts can be applied to meet the shared storage requirements of SOACS as well.

This blog describes a way to setup a high-volume file transfer process within MFTCS in OCI, where files are received in embedded SFTP server and then transferred to a remote Object Storage endpoint in OCI-Classic within Oracle Public Cloud (OPC).

Solution Approach

Use Case Basic Requirements

The overall use case can be described as follows and is also exemplified in Fig.2 below.

  • An external SFTP client sends multiple files of different sizes concurrently via SFTP to the embedded SFTP server running in MFT Cloud Service (MFTCS) within OCI.
  • MFT Server, upon receipt of the files, transfers it to an object file storage service in OCI-Classic domain URL.
  • As the MFT transfers are being executed, multiple concurrent file downloads are also processed by the SFTP server, embedded within MFTCS.
Solution Architecture

The configuration of MFT to receive files via SFTP has been discussed in one of my earlier blogs[2]. In that post, we had shown how MFT can receive files via its embedded SFTP server and save them in a local file system. In this article, we extend the use case by modifying the file system of the target endpoint to point to an object storage service endpoint within an OCI-Classic domain. The shared storage layer of DBFS is replaced with FSS. Apache jMeter is used to simulate the concurrent upload and download traffic volume, comprising of files in different sizes.
