Cloud computing is a model for delivering on-demand computing resources like servers, storage, and applications as a service. The model includes various technical services that support it. The three technical services that support cloud computing are:
VPN Connectivity: VPN or Virtual Private Network is a technology that provides secure remote access to a private network. VPN connectivity is essential for cloud computing because it allows users to access cloud resources securely over the internet. VPN connectivity ensures that the data sent between the user's device and the cloud resource is encrypted and secure.
Extended SAN Services: SAN or Storage Area Network is a high-speed network that connects servers to storage devices. Extended SAN services allow users to access storage resources that are located in different geographical locations. This service is essential for cloud computing because it enables users to access data from anywhere in the world.
Layer 3 Network Routing: Layer 3 network routing is a service that enables the routing of data between different networks. This service is essential for cloud computing because it allows users to access cloud resources from different locations. Layer 3 routing ensures that the data sent between the user's device and the cloud resource is routed efficiently and securely.
The other technical services mentioned in the question are also important for cloud computing, but they are not part of the three services that support it.
IP localization: IP localization is the process of determining the geographical location of an IP address. Although it can be useful in certain cloud computing scenarios, it is not a critical service that supports cloud computing.
Redundant connections: Redundant connections are backup connections that ensure that there is no downtime in case of a network failure. While this service is important for ensuring high availability of cloud resources, it is not a critical service that supports cloud computing.
Network-monitored power sources: Network-monitored power sources are devices that monitor and manage the power supply to network devices. This service is essential for ensuring the availability of network devices, but it is not a critical service that supports cloud computing.
