High-availability hosting FAQ

What is high-availability hosting?
High-availability hosting uses redundant servers, storage and networks with automatic failover, so an enterprise site stays online even when hardware fails or traffic spikes.
Which host is best for high availability?
SiteGround leads thanks to its redundant Google Cloud backbone and auto-scaling, with A2 Hosting and DreamHost close behind on resilient cloud infrastructure.
Do I need high-availability hosting for an enterprise?
If downtime costs your business revenue or trust, yes. A high-availability setup keeps a critical enterprise site online through faults and busy periods, unlike a single shared server.
Is cloud hosting the same as high availability?
Not always. Cloud hosting can spread a site across servers, but true high availability adds automatic failover and redundancy. Check the host offers both, not just cloud scaling.
How much does high-availability hosting cost?
Entry cloud plans start near $80 to $100 a month, and larger redundant setups cost more. The intro tiers shown here start lower, from $0.80 to $3.95, on shared or entry cloud plans.
