High-availability infrastructure, so one failure does not take you offline.
We design systems with no single point of failure: load balancing, replicated databases, automatic failover, rolling releases, backups you have restored and alerts that reach you first.
What "high availability" means in practice
High availability does not mean that nothing ever breaks. It means that when one piece breaks, such as a server, a disk or a network link, another piece takes over and customers barely notice. The work is finding the single points of failure and removing them, one by one.
Most outages come from the same short list: one database with no replica, one server running the whole application, a deployment that cannot be rolled back and a backup that nobody has tested. Each of these has a known fix, and the fixes have to be tested on purpose, because failover that has never been exercised is a guess.
What we build
No single point of failure
We map the path of a request, from DNS to database, and add redundancy at each step that can fail.
Replicated database with failover
A primary with replicas and an automatic failover process, tested by switching it off on purpose.
Load balancing and health checks
Traffic spreads across several nodes, and unhealthy ones are taken out automatically.
Safe releases
Rolling deployments with automatic rollback, so shipping new code does not take the service down.
Backups and monitoring
Backups with scheduled restore tests, and dashboards and alerts that tell you something is wrong before your customers do.
How we work
Map the risks
We list the single points of failure and rank them by how likely and how costly they are.
Remove them in order
We fix the biggest risks first, and test each fix by breaking it on purpose.
Write the runbooks
We document what to do when each thing fails, so the answer does not live in one person's head.
Keep it healthy
We can monitor and maintain the system with your team, or hand it over.
Questions
How much uptime can you guarantee?
We do not guarantee an uptime figure. We design to remove single points of failure and we prove each failover by testing it. The result is measured in your monitoring.
Do I need Kubernetes?
Not necessarily. Many teams get high availability from simpler container setups. We choose the smallest tool that does the job and that your team can run.
Does this work on dedicated servers as well as in the cloud?
Yes. The principles are the same. On dedicated servers, redundancy has to be designed in, and we do that.
Will you work with our engineers?
Yes. We document as we go and train your team, or we run the system together with them.
