Failover
With SIOS SANless application-aware clustering and replication in place, you can automate real-time failover and achieve the goal of high availability and resilience. Because we’ve chosen a software-based approach, failover occurs in the data plane, so there’s no need to spin up a new instance following an incident. Everything is already running, in sync, and ready. Furthermore, failover is immediate and it’s predictable. That is what you need when dealing with mission-critical workloads. Consider that many of the mission-critical applications you use were not designed to operate in the cloud, so even if your infrastructure is resilient, the application itself represents a single point of failure. Without replication, application monitoring, and real-time failover automation, you risk loss of revenue, security degradation, or worse.
SIOS Technology
Depending on the size of your enterprise and the industry in which it operates, an hour of downtime can cost $1 million or more, and 90% of organizations report costs of at least $300,000 per hour. Beyond that simple loss of revenue are soft costs associated with reputation damage, lost productivity, missed transactions, and more. Revenue protection is only part of the equation; it is about protecting the business.
Disaster recovery
Any design for high availability and resilience must also take into consideration the risk of a non-IT disaster that disrupts operations. Natural disasters like fires, earthquakes, and floods, or disasters caused by humans like the accidental severing of a trunkline or an act of sabotage conspire to bring operations to a sudden halt. Clustering, replication, and failover all play into disaster recovery, but there are additional considerations that must be addressed. For disaster recovery (DR), you’re going to want geographic distance between your primary site and your DR site to minimize the risk that a regional event doesn’t affect both. That means you’re going to want asynchronous (or near real-time) data replication.
