What is Cloud Computing?
A Cloud is a combination of services, network, hardware,storage and interfaces that helps delivering computing as a services.

Types of Cloud
1.) Public Cloud: The set of Hardware, Networking, storage, services, applications and interfaces owned and operated by a third party for use by other companies or individual is the public cloud.
2.) Private Cloud: The set of Hardware, Networking, storage, services, applications and interfaces owned and operated by an organization for the use of its employees, partners or customers.
3.) Hybrid Cloud: Most company use a combination of Public and Private cloud.

Types of Services
1.) IAAS(Infrastructure as a services): IAAS is the delivery of services , including an OS, storage, Network and various utility software element on a request basis.
Example are: Google compute Engine, Amazon EC2, Microsoft Azure VM
2.) PAAS(Platform as a services): PAAS is a mechanism for combining infrastructure as a services with an abstracted set of middleware services, software, development and deployment tools.
Example are: Google App Engine, Amazon Elastic Beanstalk, Microsoft Azure App service
3.) SAAS(Software as a services): SAAS is a business application created and hosted by a provider in a multi-tenant model.
Example are: Gmail,Google Drive 


Cloud Provider
1.) Amazon
2.) Google
3.) MICROSOFT
4.) Alibaba
5.) IBM

Cloud Computing: VM & Container

-
Image
Traditional Era: In this era, we have physical servers, organisations ran their application on physical servers.It was expensive for organisation to maintain many physical servers. Virtualized Era:  It is allow you to run multiple virtual machine on a single physical server CPU. VM has own operating system that's why VMs are in heavy weight in nature.  HyperVisor *   creates VM on physical servers. Container Era: Containers are similar to VMs but they are light weight in nature because containers share machine's Operating system. Container RunTime Engine  *   help to creates container on physical servers. *HyperVisor: I t is known as vm monitor. It is a software that creates and run VMs.   Types of HyperVisor: HyperVisor- 1:   The hypervisor runs directly on the underlying host system. It is also known as a “Native Hypervisor” or “Bare metal hypervisor”. It does not require any base server operating system. It has direct access to hardware resources. ...

What is the best definiton of Capacitors in 2021

-
Image
CAPACITORS A Capacitor is a passive component that has the ability to store the energy in the form of potential difference between its plates. It resists a sudden change in voltage. The charge is stored in the form of potential difference between two plates, which form to be positive and negative depending upon the direction of charge storage. A non-conducting region is present between these two plates which is called as dielectric. This dielectric can be vacuum, air, mica, paper, ceramic, aluminum etc. The name of the capacitor is given by the dielectric used. Symbol and Units: The standard units for capacitance is Farads. Generally, the values of capacitors available will be in the order of micro-farads, pico-farads and nano-farads.  The Capacitance of a capacitor is proportional to the distance between the plates and is inversely proportional to the area of the plates. Also, the higher the permittivity of a material, the higher will be the capacitance. Th...
