 CLOUD COMPUTING
➢ INTRODUCTION :-
Cloud computing is a
technology that allows
users to access and use
computing resources—
such as servers, storage,
databases, networking,
software, and more—over
the internet instead of
owning and maintaining
physical hardware and
software on-premises .

It essentially means storing and accessing data and applications over the
internet rather than on your local computer's hard drive or a company's
on-site data center.

Cloud computing emerged as a major shift in the IT

industry, moving away from the traditional on-premises data centers to
a model where IT resources are delivered as services over the internet.
This shift has allowed businesses of all sizes to leverage enterprise-level
technology with minimal upfront investment, democratizing access to
powerful computing resources. Cloud computing refers to the on-
demand delivery of IT resources over the internet with pay-as-you-go
pricing. It provides a range of services, from virtual machines and
storage to databases and networking, all hosted on a provider's remote
data centers.
➢ HISTORY OF CLOUD COMPUTING :-
1. Early Concepts and Foundations (1950s - 1970s):-
a) Mainframe Computing: The origins of cloud computing can be
traced back to the 1950s and 1960s, with the development of
mainframe computing. Organizations used centralized mainframes to
perform large-scale computing tasks, accessed by multiple users via
"dumb terminals." This concept of shared resources laid the
groundwork for cloud computing.
b) Time-Sharing: In the 1960s, the idea of time-sharing emerged,
where multiple users could access a single computer system
simultaneously. This allowed more efficient use of expensive
computing resources and was a precursor to the modern cloud model
of resource sharing.

2. Emergence of Virtualization (1970s - 1990s):-

a) Virtual Machines (1970s): IBM introduced virtualization
technology in the 1970s with the development of the virtual machine
(VM), which allowed multiple operating systems to run on a single
physical machine. This was a critical step toward the abstraction and
resource pooling seen in cloud computing.
b) Client-Server Computing (1980s - 1990s): The 1980s and
1990s saw the rise of client-server computing, where applications
were distributed between client devices and centralized servers. This
model helped establish the concept of decentralized computing, which
would later evolve into cloud computing.

3. The Birth of the Internet and Web Services (1990s):-

a) The Internet Boom: The widespread adoption of the internet in
the 1990s created the necessary infrastructure for cloud computing. It
enabled the development of web-based applications and services,
making it possible to deliver software over the internet.
b) Application Service Providers (ASPs): In the late 1990s,
Application Service Providers emerged, offering businesses access to
software applications over the internet. Although limited in scope, ASPs
were early examples of what would eventually become Software as a
Service (SaaS).

4. The Formalization of Cloud Computing (2000s):-

a) Amazon Web Services (AWS) Launch (2006): The modern era of
cloud computing began with the launch of Amazon Web Services (AWS) in
2006. AWS introduced Elastic Compute Cloud (EC2) and Simple Storage
Service (S3), which allowed users to rent virtual machines and storage
over the internet. AWS popularized the concept of Infrastructure as a
Service (IaaS) and was a major catalyst for the cloud computing
revolution.
b) Google and Microsoft: Following AWS, other tech giants like
Google and Microsoft entered the cloud market. Google introduced
Google App Engine in 2008, a Platform as a Service (PaaS) offering, while
Microsoft launched Azure in 2010, providing both IaaS and PaaS services.
c) SaaS Growth: Around the same time, Software as a Service (SaaS)
gained traction with companies like Salesforce.com offering CRM solutions
over the internet. SaaS became popular for its ease of use, scalability, and
cost-effectiveness.

5. Expansion and Maturation (2010s – Present):-

a) Hybrid and Multi-Cloud Strategies: As cloud computing matured,
organizations began adopting hybrid and multi-cloud strategies, combining
public and private clouds to optimize their IT infrastructure. This approach
offers greater flexibility, security, and cost control.
b) Edge Computing and IoT: The growth of the Internet of Things (IoT)
and the need for real-time data processing led to the rise of edge
computing, where data is processed closer to the source rather than in a
centralized cloud. This complements traditional cloud computing by
addressing latency and bandwidth concerns.
➢ CHARACTERISTICS :-
1.On-Demand Self-Service: Users can provision computing
resources such as server time and network storage automatically as
needed, without requiring human intervention from the service provider.
This allows for rapid scalability and flexibility in resource management.

2. Broad Network Access: Cloud services are available over the

network and can be accessed through standard mechanisms by various
devices, including laptops, tablets, smartphones, and workstations. This
accessibility ensures that resources are available to users regardless of
their location or the device they are using.

3. Resource Pooling: Cloud providers pool computing resources to

serve multiple customers using a multi-tenant model. These resources,
such as storage, processing, memory, and network bandwidth, are
dynamically allocated and reallocated according to demand. Users typically
do not know the exact location of the provided resources, which could be
spread across various data centers.

4. Rapid Elasticity: Cloud computing offers rapid scalability, meaning

resources can be quickly scaled up or down to meet the current demand.
This elasticity is often automated, allowing for seamless scaling without
user intervention, making it possible to handle sudden increases or
decreases in workload efficiently.

5. Measured Service: Cloud systems automatically control and

optimize resource use by leveraging a metering capability at some level of
abstraction appropriate to the type of service (e.g., storage, processing,
bandwidth). Resource usage can be monitored, controlled, and reported,
providing transparency for both the provider and consumer, typically on a
pay-per-use or subscription basis.

6. Multi-Tenancy: Multi-tenancy refers to the sharing of resources

and services among multiple clients or users. Each user’s data is isolated
and remains invisible to others, ensuring privacy and security .
7. Scalability and Flexibility: Cloud computing enables businesses to
easily scale resources up or down based on current needs. This scalability
provides flexibility to handle varying workloads and can help
organizations optimize their costs by only paying for the resources they
actually use.

8. Resilience and Redundancy: Cloud providers typically offer built-in

resilience and redundancy, ensuring high availability and minimizing
downtime. Data and applications are often replicated across multiple
locations, allowing for automatic failover in case of hardware failures or
other disruptions.

9. Security: While security is a shared responsibility between the cloud

provider and the user, cloud providers typically offer advanced security
measures, including encryption, identity and access management, and
compliance with various industry standards. They invest heavily in
securing their infrastructure, although users must also implement best
practices to protect their data.

10. Automation: Cloud environments often include automation

features that help manage and deploy resources efficiently. Automation
tools can handle tasks such as scaling, monitoring, and maintaining
services, reducing the need for manual intervention and minimizing the
risk of human error.

➢ BENEFITS :-
