RDP (Remote Desktop Protocol) is a protocol that allows a user to remotely access and control a graphical user interface (GUI) of another computer over a network. RDP can be used to install applications, configure settings, and perform administrative tasks on a cloud-hosted server. RDP is supported by Windows-based operating systems and some Linux distributions. RDP can also be accessed by using third-party software or web browsers. RDP provides a secure and encrypted connection between the client and the server, and supports features such as audio, video,clipboard, printer, and file sharing. RDP would be the best solution for a company that needs GUI-based server access to migrate an application to a cloud hosting platform.

SSH (Secure Shell) is a protocol that allows a user to remotely access and execute commands on another computer over a network. SSH can be used to install applications, configure settings, and perform administrative tasks on a cloud-hosted server. SSH is supported by most operating systems, including Windows, Linux, and macOS. SSH provides a secure and encrypted connection between the client and the server, and supports features such as port forwarding, tunneling, and file transfer. However, SSH does not provide a GUI-based access, but rather a command-line interface (CLI) that requires the user to type commands and view text-based output. SSH would not be the best solution for a company that needs GUI-based server access to migrate an application to a cloud hosting platform.

SFTP (Secure File Transfer Protocol) is a protocol that allows a user to securely transfer files between two computers over a network. SFTP can be used to upload or download files to or from a cloud-hosted server. SFTP is supported by most operating systems, including Windows, Linux, and macOS. SFTP provides a secure and encrypted connection between the client and the server, and supports features such as file permissions, directory listing, and resume interrupted transfers. However, SFTP does not provide a GUI-based or a command-line access to the cloud-hosted server, but rather a file transfer interface that requires the user to specify the source and destination paths of the files. SFTP would not be the best solution for a company that needs GUI-based server access to migrate an application to a cloud hosting platform.

HTTPS (Hypertext Transfer Protocol Secure) is a protocol that allows a user to securely access and exchange information with a web server over a network. HTTPS can be used to browse, submit, or retrieve web pages or data from a cloud-hosted server. HTTPS is supported by most web browsers and web servers, including those that run on Windows, Linux, and macOS. HTTPS provides a secure and encrypted connection between the client and the server, and supports features such as authentication, authorization, and cookies. However, HTTPS does not provide a GUI-based or a command-line access to the cloud-hosted server, but rather a web-based interface that requires the user to use a web browser and follow the web server’s logic and navigation. HTTPS would not be the best solution for a company that needs GUI-based server access to migrate an application to a cloud hosting platform. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, page 161-162; CompTIA Cloud Essentials+ Certification Training, CertMaster Learn for Cloud Essentials+, Module 4: Management and Technical Operations, Lesson 4.2: Cloud Networking, Topic 4.2.3: Remote Access Protocols
