What is an SSH
SSH, also known as Secure Shell or Secure Socket Shell, is a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network.
SSH also refers to the suite of utilities that implement the SSH protocol. Secure Shell provides strong authentication and encrypted data communications between two computers connecting over an open network such as the internet.
SSH is widely used by network administrators for managing systems and applications remotely, allowing them to log into another computer over a network, execute commands and move files from one computer to another.
Secure Shell (SSH)
SSH connections have been used to secure many different types of communications between a local machine and a remote host, including secure remote access to resources, remote execution of commands, delivery of software patches and updates and other administrative or management tasks.
The connection is private (or secure) because symmetric cryptography is used to encrypt the data transmitted. The keys for this symmetric encryption are generated uniquely for each connection and are based on a shared secret that was negotiated at the start of the session.
The server and client negotiate the details of which encryption algorithm and cryptographic keys to use before the first byte of data is transmitted.
Protect & secure your connection
When you use a public WiFi connection (for example at Starbucks or the airport), all your browsing activities when connected to a hotspot can be monitored or spied on. This allows that the person sitting next to you can read your communication easily. The worst thing is it's easy for hackers to create two Wi-Fi Hotspots, which might confuse you if it's connected to the original hotspot but in reality it's a trap.
When connected to public WiFi, unsafe WiFi, all your data including the most sensitive data such as credit card information can be very easily stolen by hackers. With the power and quality grade encryption, a VPN protects and secures your browsing sessions and keeps data from snoopers and hackers.
Cloud Server Definition
A cloud server is a sensible server that is constructed, facilitated and conveyed through a distributed computing stage over the Internet. Cloud servers have and display comparative abilities and usefulness to an ordinary server however are gotten to remotely from a cloud specialist organization. A cloud server may likewise be known as a virtual server or virtual private disjoin.
A cloud server is principally an Infrastructure as a Service (IaaS) based cloud benefit display. There are two sorts of cloud server: coherent and physical. A cloud server is thought to be legitimate when it is conveyed through server virtualization. In this conveyance demonstrate, the physical server is sensibly circulated into at least two coherent servers, each of which has a different OS, UI and applications, in spite of the fact that they share physical parts from the basic physical server.
Though the physical cloud server is additionally gotten to through the Internet remotely, it isnt shared or dispersed. This is usually known as a devoted cloud server.
