Cloud Computing: VM & Container

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. Examples of Type 1 hypervi

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

Best Definition of Diode in 2021

DIODE After having known about various components, let us focus on another important component in the field of electronics, known as a  Diode . A semiconductor diode is a two terminal electronic component with a PN junction. This is also called as a  Rectifier . The  anode  which is the  positive terminal of a diode is represented with  A and the  cathode , which is the  negative terminal is represented with  K . To know the anode and cathode of a practical diode, a fine line is drawn on the diode which means cathode, while the other end represents anode.  As we had already discussed about the P-type and N-type semiconductors, and the behavior of their carriers. Formation of a Diode: If a P-type and an N-type material are brought close to each other, both of them join to form a junction, as shown in the figure below.  A P-type material has holes as the majority carriers and an N-type material has electrons as the majority carriers. As opposite
