Examples
of Software as a Service (SaaS) include virtual desktops, communication, email,
and games. Infrastructure as a Service (IaaS) example includes servers,
storage, a virtual machine, and the network itself. Examples of the Platform as
a Service (PaaS) would include web servers, development tools, and databases.
Identity as a Service (IDaaS) can include directory management, provisioning,
or single sign-on services (SSO).

SaaS
deployments give organization the ability to run software that is installed on
the cloud. This can be cost effective as it eliminates the expense of hardware
acquisition and maintenance, as well as software licensing, installation and
support. However, businesses must rely on outside vendors to provide the
software, maintain, track and report accurate billing and facilitate a secure
environment for the business’ data. Providers that experience service disruptions
impose unwanted changes to service offerings, experience a security breach or
any other issue can have a significant effect on the customers’ ability to access
their data. Organization that uses SaaS deployments should first understand
their provider’s service-level agreement, and ensure it is enforced. With that
said, I would include Database servers-Student access, Centralized
Assessments, VPUB, Alfresco Database, VCASTLE Environment, LMSVids in the list of
SaaS deployments from the ECPI Cloud Services diagram.

Platform
as a Service (PaaS) provides organizations the capability to deploy software onto
the cloud infrastructure whether it is consumer-created or acquired
applications created using programming languages, libraries, services, and
tools supported by the provider. Organizations do not have the ability to
manage or control the underlying cloud infrastructure including network,
servers, operating systems, or storage. Instead, administrators are given control
over the deployed applications and possibly configuration settings for the
application-hosting environment. Therefore, I would include Database Servers-Student
access, Centralized Assessments, VCASTLE Environment, LMSVids in the list of
PaaS deployments from the ECPI Cloud Services diagram.

Infrastructure
as a Service (IaaS) is the foundation of cloud computing. Instead of purchasing
or leasing space, buying severs and other utilities, then paying for labor to
actually get the job done, many organization have turned to cloud storage and
other infrastructures. An IaaS provider allows organizations to rent space in a
virtual data center. Users may access the virtual data center via the Internet.
This type of cloud computing provides the “raw materials” for IT administrators,
and users usually only pay for the resources they consume. This includes CPU
cores, RAM, hard disk or storage space, and data transfer. I would include
Database Servers-Student access, Alfresco Database, VPUB in the list
of IaaS deployments from the ECPI Cloud Services diagram.

Identity-as-a-Service
(IDaaS) can be defined as any solution connecting users through secure
identities to IT resources delivered as an on-going service. Directory
Services– essentially the core user store of an organization’s users. These
identities can be delivered to IT resources through a cloud-based platform
which is often called Directory-as-a-Service® and is employed via multiple
protocols. Delivered as a SaaS-based service, this category is at the forefront
of any company’s identity management strategy. Directory Extensions–
on-premises directory services. Applications such as Microsoft Active Directory
and OpenLDAP are limited in what support is offered. I would include Faculty/Student
on and off campus, Email Server, Xendasktop, Centralized Assessments, Database
Servers-Student access, Alfresco Database, VPUB, and Campus Moodle Server.
