From redundant data centres to clusters and replication, right through to failover within seconds: this is how centron keeps your services up and running.
True high availability is not a single product, but rather the interplay between infrastructure, architecture and processes.
UPS, emergency power systems, separate fire compartments and multiple redundant power connections – the physical infrastructure at our data centre in Hallstadt near Bamberg.
Managed clusters with load balancing, real-time replication and automatic failover keep applications online – even if individual components fail.
cProtect replicates data every 15 minutes to a separate fire compartment within the Hallstadt data centre – with immutable data states and failover within seconds, even in the event of a ransomware attack.
24/7 monitoring with alerts and – in the case of managed services – proactive fault resolution by centron experts before users even notice anything is wrong.
These values are laid down in the service specifications and apply per calendar month. cProtect has no availability commitment of its own; the service follows the SLA of the infrastructure on which the failover system runs. For a highly available system, the High Availability Pool is therefore the foundation.
| Service | Value | Scope |
|---|---|---|
| ccloud³ VMs in the High Availability Pool | 99.8 % | per month · ccloud³ service specification |
| ccloud³ VMs in the Worker and Power Pool | 99.5 % | per month · ccloud³ service specification |
| Managed Server | 99.5 % / 99.8 % | Worker/Power Pool or HA Pool |
| Volumes and S3 Object Storage | 99.9 % | per month · service specification |
| Colocation network | 99.9 % | per month · Colocation service specification |
| cProtect replication interval | approx. 15 minutes | cProtect service specification |
| Customised SLAs | by arrangement | Managed Cluster and Full Managing |
Not every application requires geographical redundancy – but every one requires a well-thought-out plan. During the high-availability consultation, we analyse the costs of downtime, define RPO and RTO targets, and design the appropriate architecture: from a pair of load balancers to cross-site replication.
