Why outside help

Why Kubernetes, and why an expert partner

Kubernetes has become the standard platform for modern applications and AI. Building and running it in-house takes scarce skills and a long learning curve. An experienced partner gets you to production faster, at lower cost and with fewer mistakes.

Why Kubernetes

82%
of container users run Kubernetes in production

Up from 66% two years earlier. Kubernetes is now the default way to run modern applications.

Choosing Kubernetes means choosing the industry standard.

66%
run their generative AI on Kubernetes

Share of organisations hosting generative AI models that use Kubernetes for inference.

A platform built today is ready for the AI workloads of tomorrow.

Why a partner

46%
faster to production with expert help

Full rollout took 7 months with specialist help, against 13 months done alone.

Experienced engineers skip the trial and error.

42%
use outside partners mainly for access to talent

The top reason organisations give for using external providers, ahead of cost reduction at 34%.

Senior engineers from day one, with no hiring cycle.

About

An expert team for your platform

Cloud and on-premises, reliability and security: expertise that covers a Kubernetes platform end to end.

In charge of the engineering team are senior specialists with hands-on production experience: John, who works on cloud platforms, keeping high-traffic services reliable and secure, and Nektarios, who works on-premises, operating air-gapped Kubernetes for critical infrastructure.

Together they cover the full path a workload travels, from the virtual machine and the firewall rule to the pipeline, the cluster and the dashboard that tells you everything is healthy.

Cloud and on-premThe same engineering standard in public cloud and in a sealed data centre.
Security firstSupply-chain checks, hardening and access control in every build.
Senior hands onlyThe people you speak with are the senior engineers who do the work themselves.
Documented deliveryRunbooks, diagrams and reproducible setups your team keeps.
