Analysis of IT Infrastructure Components, Cloud, and Virtualization

This report provides a comprehensive overview of IT infrastructure components, including computer hardware platforms (SoC, community development, custom platforms), operating system platforms (AmigaOS, FreeBSD, Linux, Windows, macOS, etc.), and enterprise software applications. It explores networking/telecommunications platforms (WAN, MAN, LAN, VPN), data management and storage, and internet platforms. The report delves into cloud computing and virtualization, detailing their use cases and benefits, such as dynamic scaling of applications. It covers cloud computing service models (SaaS, PaaS, IaaS), cloud hosting services, and the core categories within cloud computing. The document also addresses cloud security issues, including dynamic scaling, subpoena issues, collocation issues, infrastructure security, and trust. It outlines the roles and responsibilities of an IT infrastructure manager, emphasizing peer and reporting staff management, vendor management, and the establishment of standards and procedures. The report also includes a bibliography of relevant sources.

Data
management and
storage:
It to the management
of the data storage
equipment's that are
used to store the user /

data. So it is a tool or
set of processes used
by an administrator to
keep your data and
storage equipment’s
safe.

consultations are
contacted for
integrating the services
of a system.
Internet
platforms:
Internet as a
collaboration platform.
Internet as a online

platform.
Internet as a education
platform.
Security issues
Cloud security issues mainly revolve around the
following issues:
Dynamic scaling of
applications with the support
of Cloud computing
The introduction of cloud computing has enabled the organizations to make
their applications scalable. The cloud computing services has certain core
categories. These are different in character and services. Cloud computing
service covers almost all online services. Cloud hosting services offers
three hybrid cloud models of cloud services.
Role and responsibility of an
IT infrastructure manager
Cloud Computing
Cloud computing is the
delivery of computing
services—servers, storage,
databases, networking,
software, analytics and more
—over the Internet (“the
cloud”). Companies offering
these computing services
are called cloud providers
and typically charge for
cloud computing services
based on usage
Virtualization
Virtualization is a
concept in computing
wherein we hide the
real resources and the
complexities of their
implementation from
end users, for various
benefits such as
security, optimization,
consolidation etc.
Use of cloud
computing and
virtualization
The cloud computing and
virtualization provides the
enterprises with the solution
that would help them in
automating their business
processes.
SaaS:
SaaS transfers
the task of
software
management
and
deployment to
other services.
PaaS:
PaaS takes care
of operating
system, network
infrastructure and
server hardware.
IaaS:
IaaS provides
their clients a
direct access to
their servers
and storage.
Dynamic
Scaling:
On-demand self-
service Ubiquitous
network access
Elasticity and
scalability Horizontal
and Vertical
Scalability
Resource Pooling
Pay-per-use
Standardized
interfaces
The subpoena issue:
Legally if the data are subpoena then
nothing force the cloud provider to
notify the user. This is a huge deal
because the users have no way to
know about the subpoena and resist it.
The collocation issue:
When an application runs in the cloud the user has no
idea who run a VM on the same hardware. It is fairly
easy for an attacker to use a VM that run on the same
hypervisor to steal your data.
The infrastructure security issue:
When in the cloud the user is relying on the cloud
provider to secure the underlying infrastructure. Since
there is no way to audit it, using a given cloud provider
it is basically a leap of faith for the user.
The trust issue:
Attesting code in the cloud is a difficult problem. It is
possible to virtualize the TPM.
