Electronic access control systems consist of hardware devices that control entry into any private premises. Theft breaches and break-ins are common crimes in business environments. Electronic access control systems are widely used because of that. ## Why an EACS software is critical? EACS software manages hardware devices, and it denies entry to unauthorized users or raises alarms on intrusion by thieves or criminals. The safety of people is directly associated with the proper execution of the EACS software. And that's why the system must always be available to security officers who must react immediately to the slightest incident. ## Key players list in EACS The key players in EACS are: * dormakaba Holding (Switzerland) * ASSA ABLOY (Sweden) * Johnson Controls (Ireland) * Allegion plc (Ireland) * Honeywell International (US) * Identiv Inc. (US) * Nedap N.V. (Netherlands) * Suprema HQ (South Korea) * Thales Group (France) * Bosch Security Systems (Germany) * NEC Corporation (Japan) * IDEMIAs (France) * HID (US) * TIL Technologies (France) ## SafeKit brings two solutions for redundancy and high availability of a EACS software ### Redundancy and high availability at the application level In this type of solution, only application data are replicated. And only the application is restared in case of failure. ![Redundancy at the application level for a EACS software](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20168%2074'%3E%3C/svg%3E)![Redundancy at the application level for a EACS software](https://safekit.eviden.com/wp-content/uploads/2023/02/application-ha-4.png) This solution requires a technical understanding of the application. You need to define which services to restart, specify the application folders to replicate, and configure a virtual IP address for failover. But this solution is platform agnostic and works with applications inside physical machines, virtual machines, in the Cloud. Any hypervisor is supported (VMware, Hyper-V...). ### Examples * Video management: [Milestone (Management, SQL, Log, Event)/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/milestone-xprotect-corporate-high-availability-synchronous-replication-failover/) * Video management: [Genetec (SQL)/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/genetec-sql-server-the-simplest-high-availability-cluster-with-synchronous-replication-and-failover-between-two-redundant-servers/) * Access control: [Nedap (AEOS, SQL)/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/nedap-high-availability-synchronous-replication-failover/) * New application (define services to restart, application folders to replicate, a virtual IP address for failover): [Windows](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/windows-high-availability-software-synchronous-replication-failover/), [Linux](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/linux-high-availability-software-synchronous-replication-failover/) ### Redundancy and high availability at the virtual machine level In this type of solution, the EACS software is put inside a virtual machine. The full Virtual Machine (VM) is replicated and restarted (Application + OS). ![Redundancy at the virtual machine level for a EACS software](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20184%20107'%3E%3C/svg%3E)![Redundancy at the virtual machine level for a EACS software](https://safekit.eviden.com/wp-content/uploads/2023/02/vm-ha-4.png) The advantage of this solution is that it does not require a technical understanding of the application; you only need to define the location of the VM files where the application is installed. This solution is generic for any EACS software. However, it works only with Windows/Hyper-V and Linux/KVM, but not with VMware. This is an active/active solution with several virtual machines replicated and restarted between two nodes. ### Examples * Building management: [Siemens Desigo CC/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-desigo-cc-redundancy-high-availability-cluster-active-active/) * Video management and access control: [Siemens Siveillance suite/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-siveillance-redundancy-high-availability-cluster-active-active/) * New application (define the location of the VM files folder where the application is installed): [Windows/Hyper-V](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/hyper-v-replication-automatic-failover-load-balancing/), [Linux/KVM](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/linux-kvm-high-availability-replication-automatic-failover-load-balancing/) More comparison between [VM HA vs Application HA](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/vm-ha-vs-application-ha/#vm-ha-vs-application-ha) ## SafeKit, a recognized solution on the security market ### Milestone has chosen SafeKit SafeKit is deployed in 30+ countries with the video management software of Milestone. [SafeKit is validated by Milestone](https://www.milestonesys.com/technology-partner-finder/evidian/milestone-redundancy-and-high-availability/) for redundancy and high availability of the management server.
