Reviewer for Cloud Computing

is a technology paradigm that enables on-demand access to

a shared pool of computing resources, such as servers, storage, databases, networking, and

software applications, over the internet.

• grid computing
• edge computing
• fog computing
• cloud computing

It allows organizations and individuals to scale

resources up or down as needed, reducing the need for upfront infrastructure investments.

• On-premises servers
• Cloud computing
• Traditional hosting
• Local data centers

Cloud computing has evolved from traditional on-premises

data centers and computing models.

• Historical Context and Evolution

• Cloud computing is limited to public data centers.
• Cloud computing has replaced all traditional computing methods.
• Cloud computing is only used for storage solutions.

Key historical developments include the advent of

virtualization, which allowed multiple virtual machines (VMs) to run on a single physical server

through the use of hypervisors. Additionally, the emergence of cloud service providers like

Amazon Web Services (AWS) in the mid-2000s revolutionized the cloud computing landscape.

• The decline of mainframe computers in the 1990s.
• Historical Context and Evolution

• The rise of physical servers in the early 2000s.
• The introduction of floppy disks in the 1980s.

provides virtualized computing resources over the

internet, allowing users to rent virtual machines, storage, and networking infrastructure.

• Data Storage
• Network Infrastructure
• Local Computing
• Infrastructure as a Service (IaaS)

Users

are responsible for managing the operating system and applications. Pros include flexibility and

control, but cons may include increased administrative burden.

• Users do not need to manage applications.
• Users are only responsible for hardware management.
• Users have no control over the operating system.
• Infrastructure as a Service (IaaS)

offers a development and deployment environment that

abstracts infrastructure management.

• Platform as a Service (PaaS)
• Network as a Service (NaaS)
• Software as a Service (SaaS)
• Infrastructure as a Service (IaaS)

Developers can focus on writing and deploying code,

while the platform handles scaling and maintenance. Pros include developer productivity, but

cons may include limitations on infrastructure customization.

• Increased infrastructure costs
• Platform as a Service (PaaS)

• Enhanced customization options
• Reduced deployment speed

delivers software applications over the internet on a

subscription basis.

• Software as a Service (SaaS)
• On-Premises Software
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)

Users access applications through web browsers, eliminating the need for

local installation and maintenance. Pros include accessibility and cost savings, but cons may

include data privacy concerns.

• local data storage
• hardware upgrades
• software updates and patches
