IaaS has a number of key benefits for organizations, which include but are not limited to these: --
- Usage is metered and priced on the basis of units (or instances) consumed. This can also be billed back to specific departments or functions.
- It has an ability to scale up and down infrastructure services based on actual usage. This is particularly useful and beneficial where there are significant spikes and dips within the usage curve for infrastructure.
- It has a reduced cost of ownership. There is no need to buy assets for everyday use, no loss of asset value over time, and reduced costs of maintenance and support.
- It has a reduced energy and cooling costs along with "green IT" environment effect with optimum use of IT resources and systems.

Structured storage is designed, maintained, and implemented by a cloud service provider as part of a PaaS offering. It is specific to that cloud provider and the way they have opted to implement systems, so special care is required to ensure that applications are not designed in a way that will lock the cloud customer into a specific cloud provider with that dependency. Unstructured storage for auxiliary files would not lock a customer into a specific provider. With volume and object storage, because the cloud customer maintains their own systems with IaaS, moving and replicating to a different cloud provider would be very easy.

Problem management is focused on identifying and mitigating known problems and deficiencies before they are able to occur, as well as on minimizing the impact of incidents that cannot be prevented. Continuity management (or business continuity management) is focused on planning for the successful restoration of systems or services after an unexpected outage, incident, or disaster. Availability management is focused on making sure system resources, processes, personnel, and toolsets are properly allocated and secured to meet SLA requirements. Configuration management tracks and maintains detailed information about all IT components within an organization.

The Russian government requires all data and processing of information about its citizens to be done solely on systems and applications that reside within the physical borders of the country. The United States, European Union, and Japan focus their data privacy laws on requirements and methods for the protection of data, rather than where the data physically resides.

Explanation
Cross-site scripting (XSS) is an attack where a malicious actor is able to send untrusted data to a user's browser without going through any validation or sanitization processes, or where the code is not properly escaped from processing by the browser. The code is then executed on the user's browser with the user's own access and permissions, allowing an attacker to redirect their web traffic, steal data from their session, or potentially access information on the user's own computer that their browser has the ability to access.
