Redundancy

Responsibility

Simployer is responsible for providing stable access for our customers 24 hours pr. day, 365 days pr. year according to our SLA.

Redundant environments

In order to achieve our promise in the SLA we rely on redundant environments with our hosting providers. In practical terms this means that we have load balancers that distributes traffic to many parallel nodes (comparable to servers if you like). I a node fails or needs to be taken offline for maintenance, the traffic is automatically distributed to the other nodes. We also have redundancy on gateway and infrastructure level, so if a whole environment (gateway and nodes) fails or needs to be taken offline for maintenance, we can redirect traffic to secondary environments. Across our hosting providers we mainly rely on Kubernetes (K8s). This is an open-source platform designed to automate the deployment, scaling, and management of containerized applications. It is widely used to orchestrate containerized workloads and services, ensuring they run efficiently and reliably.

Infrastructure as code

All our hosting environments are provisioned through code. By not relying on individual hardware and manual man-power, we can spin up new hosting environments instantly to our needs.

Zero downtime deploys

Because of our redundant environments and infrastructure as code, we are able to deploy new versions of our products without any down time for our customers and honor our SLA.
