Cloud Computing is gaining acceptance and increasing in popularity. Organizations often rely on Cloud resources to effectively replace their ‘in-house’ computer systems. In a Cloud environment, an instance is typically accepted to be a virtual system resource, established within that Cloud. Multiple instances can also form one logical instance. Multiple instances can be contained within a single node. The Cloud itself consists of multiple nodes.

In order to facilitate a Digital Forensic Investigation (DFI) a Digital Forensic Process (DFP) is followed. The DFP defines a finite number of steps to aid in the successful completion of the DFI. Isolating the environment is generally accepted within the Forensic Community to be an integral part of a Forensic process. We contend that this isolation is also needed in a DFI. The isolation prevents any further contamination of or tampering with possible evidence.

This paper serves as a starting point for a possible Digital Forensic Process (DFP) to facilitate an investigation in a Distributed Instance System (DiS) environment. It focuses on the process to isolate an instance. Conditions are introduced to act as a guide for the successful isolation of an instance. It also considers the complications that can occur when doing a digital DFI in a DiS.
