Cloud Architecture & Modernization

Architecture that uses the cloud, rather than merely running in it.

Overview

Most estates arrive in the cloud shaped by the datacentre they left. Nextherrion reshapes them: managed services where they remove operational burden, elasticity where load actually varies, and resilience designed around what the business can tolerate losing rather than around a default.

Architecture review and design, cloud-native modernization, resilience and scalability engineering, and the security posture underneath it.

Cloud Architecture Review

An assessment of the estate as it stands — cost, resilience, security posture and the decisions that are constraining it.

Cloud-Native Architecture

Designing around managed services, elasticity and failure isolation, so the platform does work you would otherwise operate yourself.

Application Modernization for Cloud

Changing applications so they can actually use what cloud offers — statelessness, horizontal scale, externalized configuration.

WHAT WE DO

Cloud Architecture Services We Offer

Containers & Orchestration

Containerized workloads and orchestration where the estate justifies the operational cost. Where it does not, we say so.

Serverless Architecture

Event-driven and serverless designs for workloads whose shape suits them — spiky, intermittent, or bound to events rather than uptime.

Resilience & Disaster Recovery

Recovery objectives agreed with the business first, then architecture to meet them — and tested, because untested recovery is a plan, not a capability.

Scalability Engineering

Designing for the load you expect and the load you would rather survive, including how the system degrades when it exceeds both.

Cloud Security Architecture

Identity, network boundaries, secrets and least-privilege access designed in, since cloud misconfiguration is a more common cause of exposure than intrusion.

OUTCOMES

What Better Architecture Changes

Managed services instead of managed servers
Capacity that follows demand
Failure contained to one component
Recovery that has been tested
Security designed in
Costs that scale with use

FAQ

Frequently Asked Questions

Do we need Kubernetes?

Sometimes. It suits estates with many services and the team to operate it, and is considerable overhead otherwise. It should be a decision with a reason attached.

Serverless or containers?

Workload shape decides it. Spiky and event-driven work suits serverless; long-running or latency-sensitive work often does not.

How much resilience do we need?

As much as the business can justify paying for. That starts as a conversation about acceptable downtime and data loss, not as a technical choice.

Is our current architecture wrong?

Usually not wrong, just shaped by earlier constraints that no longer apply. Review identifies which of those are now costing you.

Can we modernize without downtime?

Largely, with phased change and parallel running. Some cutovers need a window, and those are identified and scheduled rather than discovered.

How do you keep cloud costs under control?

Architecture decides most of it — the right service, the right size, and switching things off. Monitoring catches the rest before the bill does.
