Explore this comprehensive set of notes on cloud computing, covering fundamental concepts, key technologies, and practical applications. These notes delve into topics such as cloud service models (IaaS, PaaS, SaaS), deployment models (public, private, hybrid), virtualization, security in the cloud,...
Architecture of Cloud Computing
Cloud Computing , which is one of the demanding technology of the current time and
which is giving a new shape to every organization by providing on demand virtualized
services/resources. Starting from small to medium and medium to large, every
organization use cloud computing services for storing information and accessing it from
anywhere and any time only with the help of internet. In this article, we will know more
about the internal architecture of cloud computing.
Transparency, scalability, security and intelligent monitoring are some of the most
important constraints which every cloud infrastructure should experience. Current
research on other important constraints is helping cloud computing system to come up
with new features and strategies with a great capability of providing more advanced
cloud solutions.
Cloud Computing Architecture :
The cloud architecture is divided into 2 parts i.e.
1. Frontend
2. Backend
,The below figure represents an internal architectural view of cloud computing.
1. different security mechanisms in the backend for secure cloud resources,
systems, files, and infrastructure to end-users.
2. Internet –
Internet connection acts as the medium or a bridge between frontend and
backend and establishes the interaction and communication between frontend
and backend.
3. Database– Database in backend refers to provide database for storing
structured data, such as SQL and NOSQL databases. Example of Databses
services include Amazon RDS, Microsoft Azure SQL database and Google
CLoud SQL.
4. Networking– Networking in backend services that provide networking
infrastructure for application in the cloud, such as load balancing, DNS and
virtual private networks.

, 5. Analytics– Analytics in backend service that provides analytics capabillities for
data in the cloud, such as warehousing, bussness intellegence and machine
learning.
Benefits of Cloud Computing Architecture :
Makes overall cloud computing system simpler.
Improves data processing requirements.
Helps in providing high security.
Makes it more modularized.
Results in better disaster recovery.
Gives good user accessibility.
Reduces IT operating costs.
Provides high level reliability.
Scalability.
Cloud computing has commonly been referred to as a “stack” because it typically
encompasses many different types of services which have been built on top of each other
under a “cloud”. Cloud computing has been defined by the NIST (National Institute of
Standards and Technology) as a model that enables on-demand access to a shared
resource pool consisting of servers, networks, applications, services and cloud
storage which can be rapidly deployed with minimal management efforts. There are
three different types of cloud computing services namely Platform as a Service or PaaS,
Software as a Service or SaaS and Infrastructure as a Service or IaaS.
Who uses cloud services?
Almost everyone uses cloud services at least on customer bases. Nearly every online application uses
cloud services in a direct or indirect manner. Companies are on the way to pushing every aspect of their
business operations to the cloud and into the services-oriented methodology. If you use GitHub to manage
your code lifecycle or you provision servers on the cloud service providers then you are using cloud
services.
Benefits of using a Cloud Computing Stack
The advantages of using a cloud stack for your application are:
Resources are available on-demand, pacing the go-to-market methodology.
Focusing on the actual business improves the productivity of the development teams.
The knowledge of running the components is handled by the vendor with expertise
