Cloud computing remains a bit 'suspect when it comes to security, and not without reason. Many notable cloud services, like Google's Gmail, are just a password away from being violated, even if the advanced security options are available for this service.
Every time a business puts in the hands of third their data, some suspicion is warranted.
A solution consists in ' Adopt Google Apps, including Gmail, Google Docs, Google Calendar, Google Groups, Google Sites, Google Video, and for $ 50 per user to 'year. Among its features was announced less than the automatic backup and disaster recovery at no additional cost.
Rajen Sheth, senior product manager for Google Apps, said that customers of Google Apps does not have to worry about backup or disaster recovery.
Disaster recovery, he explains, is usually measured in terms of RPO (Recovery Point Objective) and RTO (Recovery Time Objective). RPO is the amount of acceptable data loss in case of power - the gap between the backup - and RTO is the amount of acceptable downtime before it is restored.
For large enterprises in implementing Storage Area Network (SAN), RPO and RTO are often an hour or less, says Sheth.
"For customers of Google Apps, our design goal is zero RPO and RTO our design goal is an immediate failover," he says in the blog post. "We do this through live or synchronous replication: every action in Gmail is simultaneously replicated in two data centers at once, so that if a data center does not work, almost immediately the transfer of data to the other . "
Sheth riconosce che nessun sistema è perfetto. Ma l'imperfezione è parte del piano di Google.
"Progettiamo per il fallimento", ha detto Sheth in una e-mail. "Operiamo su scala così grande che ci sono sempre server e rack server che devono essere mantenuti e migliorati. La nostra infrastruttura è progettata per darci la possibilità di intervenire quando è necessario, senza impatto sugli utenti.
