Cloud Computing Fundamentals: -
Definition of cloud computing ?
Cloud computing is a model for enabling convenient, on demand network access to a shared pool
of configurable computing resources (e.g., networks, servers, storage, applications, and services)
that can be rapidly provisioned and released with minimal management effort or service provider
interaction. Cloud computing users avoid capital expenditure (CapEx) on hardware, software,
and services when they pay a provider only for what they use.
principles of cloud computing?
1. Enablement: Plan for cloud computing as a strategic enabler, rather than as an
outsourcing arrangement or technical platform.
2. Cost/benefit: Evaluate the benefits of cloud acquisition based on a full understanding of
the costs of cloud compared with the costs of other technology platform business
solutions.
3.
Enterprise risk: Take an enterprise risk management perspective to manage the adoption
and use of cloud.
4. Capability: Integrate the full extent of capabilities that cloud providers offer with internal
resources to provide a comprehensive technical support and delivery solution.
5. Accountability: Manage accountabilities by clearly defining internal and provider
responsibilities.
6. Trust: Make trust an essential part of cloud solutions, building trust into all business
processes that depend on cloud computing.
cloud architecture and infrastructure.
Cloud Computing Architecture is divided into two parts, i.e., front-end and back-end. Front-end
and back-end communicate via a network or internet. A diagrammatic representation of cloud
computing architecture is shown below:

Front-End
 It provides applications and the interfaces that are required for the cloud-based service.
 It consists of client’s side applications, which are web browsers such as Google Chrome
and Internet Explorer.
 Cloud infrastructure is the only component of the front-end. Let's understand it in detail.

Front-end - Cloud Computing Architecture
 Cloud infrastructure consists of hardware and software components such as data storage,
server, virtualization software, etc.
 It also provides a Graphical User Interface to the end-users to perform respective tasks.
Back-End
It is responsible for monitoring all the programs that run the application on the front-end
It has a large number of data storage systems and servers. The back-end is an important and huge
part of the whole cloud computing architecture, as shown below:
Back-end - Cloud Computing Architecture

Benefits of Cloud Computing Architecture
The cloud computing architecture is designed in such a way that:
 It solves latency issues and improves data processing requirements
 It reduces IT operating costs and gives good accessibility to access data and digital tools
 It helps businesses to easily scale up and scale down their cloud resources
 It has a flexibility feature which gives businesses a competitive advantage
 It results in better disaster recovery and provides high security
 It automatically updates its services
 It encourages remote working and promotes team collaboration
