Cloud & DevOps Company in London

Decide what you want the operating model to look like at handover; the quote follows from that: a scoped landing zone build on AWS, Azure, or GCP for a London fintech or insurer, a full platform engineering engagement (EKS or AKS with ArgoCD, observability on Datadog or Splunk, policy-as-code, secrets, DORA-aligned third-party register entries), or an ongoing platform-as-a-service retainer for a London engineering team. Scope drivers include organisation structure, identity federation, network topology, baseline Terraform modules, and a reference CI/CD pipeline aligned with FCA OpResil and PRA SS2/21 expectations. London rates reflect the regulatory documentation overhead, the DORA and FCA OpResil compliance work that generic DevOps shops do not deliver, and the City of London talent premium. We quote fixed-fee on scoped deliverables, never open T and M on platform work.

FCA Operational Resilience (PS21/3 for solo-regulated firms, alongside PRA SS1/21 for dual-regulated) required firms to identify important business services, set impact tolerances, map the resources supporting each IBS, and test severe-but-plausible scenarios, with the March 2025 deadline now passed for firms to remain within their impact tolerances. Our landing zones encode the technical controls: per-IBS account or subscription boundaries, mapped dependencies in the Terraform module graph, immutable logs supporting tolerance breach detection, automated chaos engineering with AWS Fault Injection Simulator or Chaos Mesh for severe-but-plausible scenario testing, and runbook outputs that feed your FCA self-assessment. We coordinate with your operational resilience function on the IBS catalogue but own the technical evidence that proves you remain within tolerance during a tested disruption.

The Digital Operational Resilience Act (DORA) came into force across the EU on 17 January 2025 and applies to UK branches of EU financial entities and UK subsidiaries servicing EU clients. DORA codifies ICT risk management, ICT-related incident reporting, digital operational resilience testing (including threat-led penetration testing for significant firms), ICT third-party risk management with a contractual register of information, and information sharing arrangements. Our DORA-aligned engagements deliver the register of information mapped to your AWS, Azure, GCP, and SaaS dependencies, contractual clauses aligned with the DORA Articles 28 to 30 requirements (right to audit, sub-outsourcing controls, exit strategies), and the ICT incident classification and reporting workflows the European Supervisory Authorities expect. For firms with both UK FCA OpResil and EU DORA obligations we deliver a unified evidence model rather than two parallel documentation tracks.

AWS eu-west-2 (London) opened in 2016 and is the default primary region for UK regulated workloads because it places data inside the UK boundary, which simplifies UK GDPR and Data Protection Act 2018 evidence packs. eu-west-1 (Ireland) is the default DR region because it is the largest, most-mature AWS region in Europe with the deepest service availability, and the UK-EU adequacy decision (currently in place until December 2025, with extension under negotiation) keeps data flows lawful. We adjust this default in two scenarios. First, if your data classification rules out any EU storage (rare but seen in defence-adjacent or sensitive government work), we switch DR to a UK-only posture using AWS Local Zones or an Azure UK South plus UK West pairing. Second, if Brexit data flow constraints tighten or adequacy lapses, we have eu-west-3 (Paris) and Azure France Central documented as alternates. The decision is driven by your data classification, not by hyperscaler convenience.

Yes. PRA SS2/21 (and the parallel FCA SYSC 8 framework) covers outsourcing and third-party risk management for PRA-regulated firms, with material outsourcing arrangements requiring written agreements, exit strategies, and PRA notification under SUP 15. Our engagements deliver the technical artefacts that make the supervisory expectation defensible: documented data flow diagrams covering every cloud and SaaS dependency, exit strategy runbooks tested at least annually (not just written), sub-outsourcing controls expressed as contractual constraints flowed down to AWS, Azure, and GCP, and concentration risk analysis showing whether your hyperscaler dependency creates a systemic single point of failure. For Material Outsourcing arrangements we coordinate with your third-party risk function on the PRA notification but own the technical evidence that supports it.

Both, depending on your risk posture. GitHub Actions is the de facto standard for London product engineering teams (including most London SaaS and increasingly the challenger banks like Monzo and Starling) and we deliver hardened reusable workflows, OIDC federation to AWS or Azure, environment protection rules with required reviewers, and secret scanning plus dependency review enforced on every pull request. For air-gapped finance estates (typically core banking, trading systems, or any Lloyd''s market workload subject to PRA SS2/21 material outsourcing) we deliver self-hosted GitLab on EKS with JFrog Artifactory for binary management (the standard for City of London finance), Sigstore Cosign for signed artefact verification, and the change advisory board integration your operational risk function requires. Pipeline outputs feed your existing Splunk or ELK SIEM with retention configured to FCA SYSC 9 and PRA Rulebook requirements.

London observability stacks are more diverse than New York''s Datadog default. Datadog is common in the challenger bank and SaaS layer, Splunk dominates the bulge bracket and Lloyd''s market for log management and SIEM (driven by its long-standing London presence and historic financial services adoption), Grafana plus Prometheus plus Loki plus Tempo is the open-source default for engineering-heavy teams, and ELK remains widely deployed for log analytics. Our engagements typically include APM with distributed tracing, infrastructure monitoring tagged per important business service for FCA OpResil mapping, log management with retention tied to FCA SYSC 9 record-keeping requirements (currently five years for most categories), real user monitoring on customer surfaces, and synthetics for critical user journeys. SLOs are defined per IBS with error budgets that link to your impact tolerances, so a sustained SLO breach automatically triggers your operational resilience self-assessment workflow.

Yes. Crown Commercial Service frameworks (Cloud Compute, G-Cloud 14, Digital Outcomes) govern most UK government cloud procurement, and London firms working on local authority, NHS, or central government contracts often need framework alignment even when not the primary supplier. We build inside AWS UK regions and Azure UK regions with the appropriate impact level (typically OFFICIAL with OFFICIAL-SENSITIVE handling), deliver the NCSC Cloud Security Principles documentation, Cyber Essentials Plus evidence, and ISO 27001:2022 control mappings that public sector buyers require. We do not lead G-Cloud listing but deliver the technical artefacts that support a supplier''s submission, including data residency proofs, encryption and key management documentation, and the staff vetting and physical security mappings the buyer''s due diligence demands.
