How will Clinicea handle downtime
Data durability and fault tolerance is secured by maintaining multiple copies of all data in different physical nodes located across fully independent physical sub-systems such as server racks and network routers. At any one time, we keep three replicas of data running—one primary replica and two secondary replicas. If hardware fails on the primary replica, our system auto-detects the failure and fails over to the secondary replica. In case of a physical loss of the replica, our system creates a new replica automatically. Therefore, there are at least two physical transactionally consistent copies of your data in the data center, at any given moment.
Backups are no longer daily, as that would lead to a loss of data between the between first backup and the second one. SQL Azure offers real-time snapshots of data down to the last 5 minutes. This is offered as part of the “Premium Series Offering” i.e., P1 onwards. Clinicea is an early adopter of this service as well and hence our clients enjoy real-time snapshots as well.
Every component of Clinicea architecture i.e., Servers, routers, switches, load balancers, firewall, and database is exclusively hosted within highly secure data centers managed and operated by Microsoft Global Foundation Services (GFS). These geographically dispersed data centers comply with key industry standards, such as ISO/IEC 27001:2005, for security and reliability. They are managed, monitored, and administered by Microsoft operations staff that have years of experience in delivering the world’s largest online services with 24 x 7 continuity.
To ensure you get the complete picture, downtime is still possible in the event that Microsoft Azure itself goes down. This though a rare event, has happened. Once in 2 years, we do hear of global outages where Amazon, Google, Facebook, or Azure goes down for a few hours due to new a vulnerability identified in their system. Unfortunately, there is no solution to that as of today, if the hosting company itself goes down. Other than that, Clinicea by itself is well architected with redundancy and high availability built-in with the use of only cloud Paas services, multiple auto-scale nodes, and real-time health check-driven automated switchovers, to ensure uptime under all circumstances.
