RAID 5 is a disk array configuration that uses parity to provide fault tolerance and data recovery. RAID 5 can tolerate the failure of one disk, but not two or more disks. If a second disk fails during the resynchronization process, the data on the RAID 5 array will be lost and unrecoverable. The only way to make the server fully operational is to restore the data from a backup source.

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.

Playbook and templates are two things that must be used to deploy a cloud solution to its provider using automation techniques. A playbook is a file or script that defines a set of tasks or actions to be executed on one or more cloud resources or systems. A playbook can automate and standardize the deployment and configuration of cloud solutions using tools such as Ansible, Chef, Puppet, etc. A template is a preconfigured image or blueprint of a cloud resource or system that contains an OS, applications, settings, etc., that can be used to create new resources or systems quickly and consistently. A template can simplify and speed up the deployment of cloud solutions using tools such as AWS CloudFormation, Azure Resource Manager, Google Cloud Deployment Manager, etc.
