SAAS & SAASSELECTMultiple levels ofredundancy—including harddrives, servers, and network“clusters”—ensure the safety ofclient data by removing anypotential single point of failure.REDUNDANCYSystem BackupsYardi SaaS and Yardi SaaS Select are designed around a system architecture that includes multiplelevels of redundancy to ensure maximum protection of client data. Client programs and linked filesare stored on RAID disk arrays. Every hosted client database is replicated on a separate hard drive,which, in turn, is replicated on a server. Within each data center, multiple independent networkclusters provide another level of redundancy by removing any potential single point of failure. Inaddition, all client databases and their log files (transaction logs) are copied to a separate backupserver. Log files are backed up at 30-minute intervals, so database transactions can be readilyrecovered to a specific point in time if the original log files are unavailable.Furthermore, all client data is backed up nightly to a secure, on-site FTP server that is accessible to adesignated user for each client. As an added precaution, Yardi strongly recommends that clientsregularly download and archive their database backups from this client-accessible server. Nightlybackups of client data are stored on the FTP server for two weeks, after which they are deleted tomake room for new backups. If necessary, clients may purchase longer periods of storage on theserver.Business Continuity PlanYardi replicates every “live” Microsoft SQL or Oracle database in real-time to a standby server at ageographically remote recovery data center. These standby servers are designated as recovery serversand are used only for that purpose, as in the case of a catastrophic failure affecting an entire datacenter. Using a secure VPN connection to access the Internet, we transfer all database transactionsand client user default paths in real-time to these servers.Yardi initiates recovery after access to the client’s hosted site has been unavailable for 24 hours. Yardiwill have each client’s database restored within five business days and will notify each client as theirdatabase becomes available. For an additional service fee, these recovery periods can be adjusted tomeet specific client needs. We also offer business continuity for other hosted applications; please seeyour Yardi representative for details.6
SAAS & SAASSELECTBackup generators, redundantHVAC, and multiple ISPs ensurethat site and network operationare never compromised.Site and Network RedundancyEach data center is equipped with backup generators to ensure an uninterrupted power supply (UPS)for the site in the event of a catastrophic power failure. Similarly, every data center has redundantheating, ventilation, and air conditioning (HVAC) to ensure that the controlled server environmentessential for optimal system performance is not compromised by hardware failure. In addition, Yardihosting uses multiple ISPs for each of its data centers to ensure uninterrupted Internet access in theevent that any single provider’s network becomes compromised.Collectively, these precautionary measures equate to uninterrupted business continuity for Yardi SaaSand Yardi SaaS Select clients, enabling them to focus their energy where it counts—on maximizingthe productivity and profitability of their business.SCALABILITYClients can readily increaseprocessing capacity as theirbusiness grows, withouthaving to purchase, install, andmaintain additional hardwareand software.Growing with the ClientOne of the key benefits of our SaaS solutions is the ease with which they allow clients to increase theirprocessing capacity as their business grows. Yardi’s data centers maintain excess capacity at all times,so clients can add new users and modules quickly as demands increase. No matter how rapidly ourclients grow, there are always enough servers on the Yardi network to meet their needs readily.Conversely, if clients ever need to scale back their operations, they can do so without having to suffera loss of investments made in unused software and hardware.7
