What is the difference between failover and redundancy?

Redundancy is having extra components available in the case a component fails. Failover is the mechanism, be it automatic or manual, for bringing up a contingent operational plan.

What feature in Hyper-V provides high availability of applications and server workloads that are not?

How Hyper-V High Availability Works. Failover clustering is the process of combining several independent computers (called nodes) into a single group that enables a high level of availability and scalability of applications and services. Clustered servers can be connected by physical cables as well as by software.

What is redundancy in server?

What is a Redundant Server? A redundant server is like having a spare tire for your network. It’s essentially a duplicate of your system – including lines of communication and network devices – that can act as your business’s main operating system if your primary server goes down for any reason.

What is the difference between HA and redundancy?

High Availability vs. The primary goal of high availability is to ensure system uptime even in the event of a failure. Redundancy, on the other hand, is the use of additional software or hardware to be used as backup in the event that the main software or hardware fails.

What are some disadvantages of Hyper-V?

Hyper-V Disadvantages:

  • A crash of the primary OS will crash all VMs.
  • OS must be installed in order for the Hypervisor Layer to operate.
  • Frequent OS and security updates translate into more overhead.
  • Lack of support for service templates.

How Hyper-V memory management differs from other virtualization products like VMware?

The difference is that VMware offers dynamic memory support for any guest OS, and Hyper-V has historically supported dynamic memory only for VMs that run Windows. However, Microsoft added dynamic memory support for Linux VMs in Windows Server 2012 R2 Hyper-V.

Does Hyper-V have fault tolerance?

Hyper-V itself has no true fault tolerance capability. It is built on the Windows Server kernel which can compensate for some hardware failures, but overall, it relies on hardware features to provide true fault tolerance.

What is failover clustering in Hyper-V?

What is Hyper-V failover cluster? Failover cluster is a set of several similar Hyper-V servers (called nodes), which can be specifically configured to work together, so that one node can take the load (VMs, services, processes) if another one goes down or if there is a disaster.

How does Hyper-V make server management easier?

By supporting a broad range of guest operating systems, Hyper-V enables businesses handle workloads more efficiently, and to manage both virtual and physical resources using the same industry-standard tools.

What is the App-V management server?

Provides a centralized console to manage App-V infrastructure and delivers virtual applications to both the App-V Desktop Client and a Remote Desktop Services Client. The App-V management server authenticates, requests, and provides the security, metering, monitoring, and data gathering required by the administrator.

Can App-V be deployed in a highly available service level?

Microsoft Application Virtualization (App-V) system configurations can take advantage of options that maintain a high available service level. The following sections will help you understand the options to deploy App-V in a highly available configuration.

What is the dual admin management method for App-V?

Studio and the App-V servers must remain synchronized, particularly for user permissions. This is called the dual admin management method because App-V package and application access requires both Studio and the App-V server consoles. This method works best in closely coupled App-V and Citrix deployments.

What is Microsoft Application virtualization (app-V)?

Microsoft Application Virtualization (App-V) lets you deploy, update, and support applications as services. Users access applications without installing them on their own devices.
