A Type 2 hypervisor differs from a Type 1 hypervisor in that it runs on top of another operating system rather than directly tied into the underlying hardware of the virtual host servers. With this type of implementation, additional security and architecture concerns come into play because the interaction between the operating system and the hypervisor becomes a critical link. The hypervisor no longer has direct interaction and control over the underlying hardware, which means that some performance will be lost due to the operating system in the middle needing its own resources, patching requirements, and operational oversight.

Infrastructure as a Service pools the compute resources for platforms and applications to build upon, including CPU, memory, and storage. Applications are not part of an IaaS offering from the cloud provider.

A reservation is a minimum resource that is guaranteed to a customer within a cloud environment. Within a cloud, a reservation can pertain to the two main aspects of computing: memory and processor. With a reservation in place, the cloud provider guarantees that a cloud customer will always have at minimum the necessary resources available to power on and operate any of their services.

A virtual area network (VLAN) can span any networks within a data center, or it can span across different physical locations and data centers.

Virtual private networks (VPNs) are commonly used to allow access into trust zones. Via a VPN, access can be controlled and logged and only allowed through secure channels by authorized users. It also adds an additional layer of encryption and protection to communications.

No matter what kind of application, system, or hosting model used, encryption is 100 percent dependent on encryption keys. Properly securing the keys and the exchange of them is the biggest and most important challenge of encryption systems.

With static masking, a separate and distinct copy of the data set is created with masking in place. This is typically done through a script or other process that takes a standard data set, processes it to mask the appropriate and predefined fields, and then outputs the data set as a new one with the completed masking done.

The functions of the management plane are typically exposed as a series of remote calls and function executions and as a set of APIs. These APIs are typically leveraged through either a client or a web portal, with the latter being the most common.

With international operations, systems ultimately cross many jurisdictional boundaries, and many times, they conflict with each other. The major hurdle to overcome for an organization is the lack of an ultimate international authority to mediate such conflicts, with a likely result of legal efforts in each jurisdiction.

The concept of shares within a cloud environment is used to mitigate and control the request for resource allocations from customers that the environment may not have the current capability to allow. Shares work by prioritizing hosts within a cloud environment through a weighting system that is defined by the cloud provider. When periods of high utilization and allocation are reached, the system automatically uses scoring of each host based on its share value to determine which hosts get access to the limited resources still available. The higher the value a particular host has, the more resources it will be allowed to utilize.

Deletion merely removes the pointers to data on a system; it does nothing to actually remove and sanitize the data. As such, the data remains in a recoverable state, and more secure methods are needed to ensure it has been destroyed and is not recoverable by another party.

Due to the lack of an adequate privacy law or protection at the federal level in the United States, European privacy regulations generally prohibit the exporting or sharing of PII from Europe with the United States. Participation in the Safe Harbor program is voluntary on behalf of an organization, but it does require them to conform to specific requirements and policies that mirror those from the EU. Thus, organizations can fulfill requirements for data sharing and export and possibly serve customers in the EU.

With multitenancy, eDiscovery becomes more complicated because the data collection involves extra steps to ensure that only those customers or systems that are within scope are turned over to the requesting authority.

Under the Federal Rules of Civil Procedure, data custodians are assumed and expected to have full and comprehensive knowledge of the internal design and architecture of their systems. In a cloud environment, especially with PaaS and SaaS, it is impossible for the data custodian to have this knowledge because those systems are controlled by the cloud provider and protected as proprietary knowledge.
