This is the best solution to achieve the objective of reducing current RTO (Recovery Time Objective) from 12 hours to one hour, and RPO (Recovery Point Objective) from one day to eight hours, at the lowest cost possible, for a website that uses mostly static files and a small relational database. RTO is a metric that measures how quickly a system or service can be restored after a disruption or disaster. RPO is a metric that measures how much data can be lost or how far back in time a recovery point can be without causing significant impact or damage. To reduce RTO and RPO, the administrator should implement a website replica in the cloud with auto-scaling using the smallest possible footprint. A website replica is a copy or backup of a website that can be used for recovery or failover purposes. Auto-scaling is a feature that allows cloud resources or systems to adjust their capacity and performance according to demand or workload. Using auto-scaling with the smallest possible footprint can minimize costs by using only the necessary resources and scaling up or down as needed. The administrator should also use DNS (Domain Name System) to shift the load from on premises to the cloud. DNS is a service that translates domain names into IP addresses and vice versa. Using DNS, the administrator can redirect traffic from the on-premises website to the cloud replica in case of a disruption or disaster, and vice versa when recovery is complete.

Explanation
A type 1 hypervisor is what would best meet the requirements of high-performance VMs (Virtual Machines), more secure, and has system independence for a company that wants to move its environment from on premises to the cloud without vendor lock-in. A hypervisor is a software or hardware that allows multiple VMs to run on a single physical host or server. A hypervisor can be classified into two types:
Type 1 hypervisor: This is a hypervisor that runs directly on the hardware or bare metal of the host or server, without any underlying OS (Operating System). A type 1 hypervisor can provide benefits such as:
High-performance: A type 1 hypervisor can provide high-performance by eliminating any overhead or interference from an OS, and allowing direct access and control of the hardware resources by the VMs.
More secure: A type 1 hypervisor can provide more security by reducing the attack surface or exposure of the host or server, and isolating and protecting the VMs from each other and from the hardware.
System independence: A type 1 hypervisor can provide system independence by allowing different types of OSs to run on the VMs, regardless of the hardware or vendor of the host or server.
Type 2 hypervisor: This is a hypervisor that runs on top of an OS of the host or server, as a software application or program. A type 2 hypervisor can provide benefits such as:
Ease of installation and use: A type 2 hypervisor can be easily installed and used as a software application or program on an existing OS, without requiring any changes or modifications to the hardware or configuration of the host or server.
Compatibility and portability: A type 2 hypervisor can be compatible and portable with different types of hardware or devices that support the OS of the host or server, such as laptops, desktops, smartphones, etc.
