Cloud computing has evolved to be the game changer in the present-day fast-paced digital world of ours. It has revolutionized business in terms of information storage and access, people accessing online services and activities. As a business person, developer, or simply someone who uses computers, cloud enables you to realize your digital lifestyle.
What is Cloud Computing?
Cloud computing provides computing services, including servers, storage, databases, networking, software, analytics and intelligence, over the Internet (the cloud) to realize faster innovation and flexible resources and economies of scale. Companies can rent access to unlimited applications or storage, and with data, cloud service providers rent them the physical data centers or servers.
Essence of Cloud Computing
On-Demand Self-Service : This feature enables consumers to use resources such as storage area or servers, and so on, on demand and with no human interaction.
Accessibility: Access to services is provided on the internet and it can be reached by any device with connection.
Resource Pooling: Cloud suppliers offer to several clients with the possibility of scaling resources which are dynamically assigned.
Rapid Elasticity: Ability to adjust the resources rapidly with regards to demand.
Metered Service: Cloud systems have metering of resources consumed in automatic optimized control.
Kinds of Cloud Computing
Public Cloud
They are third-party providers, such as AWS, Microsoft Azure Google Cloud, and are provided and delivered with internet delivery and shared across many users.
Private Cloud
Belonging to one organization only. It is more secured and controllable and it might be more expensive and demanding on management.
Hybrid Cloud
Integrates both the public and the privately managed clouds, enabling both the data and applications to be transferred between the two clouds and thus provides desirable flexibility.
Types of Cloud Computing :
Cloud Computing Service Models
IaaS Infrastructure as Service
Provides the delivery of the virtualized resources (e.g., servers, storage) over internet.
Ex: Amazon EC2
PaaS Service (platform as a service)
Provides hardware and software tools on the internet, mostly used in development of applications.
An example is Google App Engine.
A Service as of software (SaaS)
Provides the software applications on a subscription basis through the internet.
Exemple de cas d’utilisation: Dropbox, Microsoft 365.
The strengths of using Cloud Computing are:
Cost effective – pay as you go.
Scalable: Easily expand and reduce in both directions, according to whatever demand has.
Reliable: Makes possible Disaster recovery, data backup and high availability.
Safe: There are advanced security measures to protect confidential information.
Eco-Friendly : green can be made through resourcefulness that can minimize carbon footprints
