Always-on customer platforms

When customers arrive all at once, the data platform behind your service decides whether they stay. Digitalis designs and runs highly available platforms on Apache Cassandra, Apache Kafka and Kubernetes that keep latency low and stay online through traffic spikes, with 24×7 support.

What an always-on platform makes possible

  • Handle event-day spikes. Capacity is planned for the busiest hour, so peaks do not slow the service.
  • Give customers instant access to their data. Records such as bets, orders or posts are available the moment customers ask for them.
  • Stay online through failures. Replication across zones and data centres means a failed node or site does not take the service down.
  • Grow without a rebuild. Platforms scale out across more machines as the customer base grows.

What we bring

The services and technologies behind it

Architecture designed for the busiest hour

We design for peak load, high availability and disaster recovery from the start, with capacity planned around real traffic patterns.

Consultancy services

Distributed databases for data that must always be available

Replicated, fault-tolerant storage keeps customer data available and fast, even when parts of the platform fail.

Our technologies

Event-driven services that scale independently

Event streaming and container orchestration let each part of the service scale on its own, so a spike in one area does not slow the rest.

DevOps and SRE services

24×7 support for the moments that matter

Specialist engineers monitor the platform around the clock and respond to incidents day or night.

24×7 managed service

Frequently asked questions

How do you prepare a platform for peak events?

We plan capacity against expected peaks and agree runbooks with your team, and our engineers watch the platform around the clock.

Why use Apache Cassandra for always-on services?

Apache Cassandra replicates data across nodes and data centres with no single point of failure, so it keeps serving reads and writes when hardware or a whole site fails.

Can you fix a platform that already struggles at peak?

We start by reviewing architecture, capacity and configuration, then fix the bottlenecks in order of impact. Where the design itself is the limit, we plan a step-by-step move to a more scalable one. See migration and modernisation.

Do you work on any cloud?

We are cloud-agnostic and work on any cloud, including hyperscalers such as AWS, Azure and Google Cloud, European sovereign clouds such as Scaleway and IONOS, and on-premises or hybrid environments. See our cloud-agnostic services.
