According to 1, cloud service models are categories of services that cloud providers offer to users and businesses. The three cloud service models are:

• Software as a Service (SaaS): The provider delivers software applications over the internet that users can access via web browsers or mobile apps. Examples: Gmail, Salesforce, Netflix.
• Infrastructure as a Service (IaaS): The provider offers computing resources such as servers, storage, networks and virtual machines that users can rent and manage via a web portal or an API. Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP).
• Platform as a Service (PaaS): The provider offers a web-based environment where developers can build cloud applications using a database, operating system and programming language provided by the provider. Examples: Heroku, Google App Engine, AWS Elastic Beanstalk.

Based on these definitions12, the cloud service model that provides compute, network and storage resources through self-service portal is Infrastructure as a Service(IaaS)34. This is because IaaS allows users to rent and manage computing resources via a web portal or an API without having to maintain the underlying elements2.

In a full mesh topology, every switch is connected to every other switch, providing multiple paths for redundancy and performance. This setup is ideal for meeting performance requirements and ensuring that there is always a path available even if one link fails, fulfilling the need for redundant ISLs.

A Demilitarized Zone (DMZ) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger, untrusted network, typically the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external attacker only has access to equipment in the DMZ, rather than any other part of the network. This mechanism secures internal assets while allowing Internet-based access to selected resources.
