  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 ac...

Cloud computing  is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote  data center  managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.   Compared to traditional on-premises IT, and depending on the cloud services you select, cloud computing helps do the following: Lower IT costs:  Cloud lets you offload some or most of the costs and effort of purchasing, installing, configuring, and managing your own on-premises infrastructure.  Improve agility and time-to-value:  With cloud, your organization can start using enterprise applications in minutes, instead of waiting weeks or months for IT to respond to a request, purchase and configure supporting hardware, a...

  SSH Meaning| SSH Protocol Definition SSH stands for  Secure Shell or Secure Socket Shell . It is a cryptographic network protocol that allows two computers to communicate and share the data over an insecure network such as the internet. It is used to login to a remote server to execute commands and data transfer from one machine to another machine. The SSH protocol was developed by  SSH communication security Ltd  to safely communicate with the remote machine. Secure communication provides a strong password authentication and encrypted communication with a public key over an insecure channel. It is used to replace unprotected remote login protocols such as  Telnet, rlogin, rsh, etc ., and insecure  file transfer protocol  FTP . Its security features are widely used by network administrators for managing systems and applications remotely. The SSH protocol protects the network from various attacks such as  DNS spoofing , IP source routing, and IP ...

  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 ...

  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 u...

  Switching When a user accesses the internet or another computer network outside their immediate location, messages are sent through the network of transmission media. This technique of transferring the information from one computer network to another network is known as  switching . Switching in a computer network is achieved by using switches. A switch is a small hardware device which is used to join multiple computers together with one local area network (LAN). Network switches operate at layer 2 (Data link layer) in the OSI model. Switching is transparent to the user and does not require any configuration in the home network. Switches are used to forward the packets based on MAC addresses. A Switch is used to transfer the data only to the device that has been addressed. It verifies the destination address to route the packet appropriately. It is operated in full duplex mode. Packet collision is minimum as it directly communicates between source and destination. It does no...
