NAKIVO Backup & Replication with Site Recovery is a turn-key solution that provides integrated protection against data loss. Unlike HA and FT, disaster recovery is a much broader and more complex concept that refers to a strategy with a comprehensive set of components including: risk assessment, planning, dependencies analysis, remote site configuration, staff training, testing, automation setup, and so on. All you need to do is bring your code to start doing what you already love. In virtualization, redundancy is achieved through keeping and running identical copies of a given virtual machine on a separate host. There are two small drawbacks of fault tolerance however; it is more costly because both servers are running all the time and there is a risk of both servers going down if there is a problem with the operating system that the servers are using. addEvent(form_to_submit, 'submit', form_submit); (a[n]=a[n]||[]).hide=h;setTimeout(function(){i();h.end=null},c);h.timeout=c; ); (_above|_below) ?/g, '') + ' _below'; Fault tolerant solutions have the ability to keep operating even if a component, or multiple components, should fail. }; The availability of data and applications is a core requirement for any application, whether it is on-premises or in the cloud. if (window._old_serialize) window.serialize = window._old_serialize; Like disaster recovery, high availability is a strategy that requires careful planning and the use of tools. } else if (typeof(trackcmp_url) != 'undefined' && trackcmp_url) { How tolerant are your networks to failure? resize_tooltip(tooltip) : false; Because the cost of downtime is high, whether we are talking about dollar figures (at just 5 hours of downtime per year, the estimated dollar cost is $1.3 million based on extrapolated data from the Aberdeen Group), the lost productivity of your staff resorting to manual processes, or the lives of your patients who are at risk every second that your systems are offline.

So if something happens to resources in one data center, the other data center can take over. Managed HSM pools use a different high availability and disaster recovery model.

This way, you can make sure that your site recovery workflows are valid, and that they reflect all recent changes that took place in your IT infrastructure, in order to exclude any possible weaknesses before actual disaster hits. visitorObject('setEmail', email); if (_removed) return; With this service you can replicate an Azure VM and even on-premises VMs and physical servers to a different region (from a primary location to a secondary location). For example, in the case of Azure, one way fault tolerance has been built in is by having regions that contain multiple data centers. For example, when one of your hosts or virtual machines (VM) within a cluster fails, another VM takes over and maintains the proper performance of the system. While high availability and fault tolerance are exclusively technology-centric, disaster recovery encompasses much more than just software/hardware elements. When replicating between two sites that you control, your virtual machines’ data and replication stays on your networks and all communication with Azure is encrypted. } When your systems run into trouble, that’s where one or more of the three primary availability strategies will come into play: high availability, fault tolerance, and/or disaster recovery. }; return new_tooltip; Additionally, Microsoft Azure also offers DRaaS, or disaster recovery as a service.
