 Types of cloud computing

Public cloud is a type of cloud computing in which a cloud Service Provider makes computing resources—anything from SaaS applications, to individual Virtual machines (VM), to bare metal  to complete enterprise-grade infrastructures and development platforms—available to users over the public internet. These resources might be accessible for free, or access might be sold according to subscription-based or pay-per-usage pricing models. Public cloud is a Multi-tenant environment —the cloud provider's data center infrastructure is shared by all public cloud customers. In the leading public clouds—Amazon Web Services (AWS), Google Cloud, IBM Cloud, Microsoft Azure, and Oracle Cloud—those customers can number in the millions.


Private cloud is a cloud environment in which all cloud Infrastructure and computing resources are dedicated to, and accessible by, one customer only. Private cloud combines many of the benefits of cloud computing—including elasticity, scalability, and ease of service delivery—with the access control, security, and resource customization of on-premises infrastructure. A private cloud is typically hosted on-premises in the customer's data center. But a private cloud can also be hosted on an independent cloud provider’s infrastructure or built on rented infrastructure housed in an offsite data center.

Hybrid cloud is just what it sounds like—a combination of public and private cloud environments. Specifically, and ideally, a hybrid cloud connects an organization's private cloud services and public clouds into a single, flexible infrastructure for running the organization’s applications and workloads. The goal of hybrid cloud is to establish a mix of public and private cloud resources—and with a level of orchestration between them—that gives an organization the flexibility to choose the optimal cloud for each application or workload and to move workloads freely between the two clouds as circumstances change. This enables the organization to meet its technical and business objectives more effectively and cost-efficiently than it could with public or private cloud alone.

Switch Vs. Router

  Switch Vs. Router | Difference between Switch and Router The switch and router are the two essential components of a network. Although both are the connecting devices in a network, and sometimes people assume them as the same, both have different functionality. In this topic, we will see how the switch and  router are differentiated from each other. What is a Switch? A switch is a networking device, which provides the facility to share the information & resources by connecting different network devices,  such as  computers, printers, and servers,   within a small business network. With the help of a switch, the connected devices can share the data & information and communicate with each other. Without a switch, we cannot build a small business network and cannot connect devices within a building or campus. Types of Switch There are mainly two types of switches in the network, which are given below: Unmanaged Switches The unmanaged switches are mainly used for basic connectivi

IP Address Format and Table

  IP Address Format and Table IP address is a short form of "Internet Protocol Address." It is a unique number provided to every device connected to the internet network, such as Android phone, laptop, Mac, etc. An IP address is represented in an integer number separated by a dot (.), for example, 192.167.12.46. Types of IP Address An IP address is categorized into two different types based on the number of IP address it contains. These are: IPv4 (Internet Protocol version 4) IPv6 (Internet Protocol version 6) What is IPv4? IPv4 is version 4 of IP. It is a current version and the most commonly used  IP  address. It is a 32-bit address written in four numbers separated by a dot (.), i.e., periods. This address is unique for each device. For example, 66.94.29.13 What is IPv6? IPv4 produces 4 billion addresses, and the developers think that these addresses are enough, but they were wrong. IPv6 is the next generation of IP addresses. The main difference between IPv4 and IPv6 is t

SNMP (Simple Network Management Protocol)

  SNMP (Simple Network Management Protocol) SNMP was defined by  IETF (Internet Engineering Task Force) . It is used to manage the network. It is an internet standard protocol that monitors devices in IP networks and collects and organizes the information (data) of these devices. SNMP is supported by most network devices such as the hub, switch, router, bridge, server, modem, and printer, etc. The concept of SNMP is based on the manager and agent. A manager is like a host that controls a group of agents, such as routers. SNMP Manager:  It is a computer system that monitors network traffic by the SNMP agent, and it queries these agents, takes answers, and controls them. SNMP Agent:  It is a software program that is located in a network element. It collects real-time information from the device and passes this information to the SNMP manager. Management components It has two components SMI MIB SNMP: It defines the structure of packets that is shared between a manager and an agent. SMI (S
