Peak Delivery is a senior-led UK consultancy. We design and deliver cloud, infrastructure and modern workplace platforms for organisations where the architecture has to stand up to real scrutiny — financial services, defence, utilities and the public sector.
Enterprise-scale landing zones on Azure and AWS, aligned to the Microsoft Cloud Adoption Framework. Identity, networking, policy, governance — built once, built correctly, ready to onboard new regions and workloads.
Azure Virtual Desktop and Windows 365, Microsoft 365 (Exchange, Teams, Intune, SharePoint), and the conditional-access and device-management layer that holds it all together. Real experience replacing Citrix at enterprise scale.
Identity-first security, Zero Trust segmentation, SASE, and cloud connectivity (ExpressRoute, hub-and-spoke, regional architectures). Designs that survive scrutiny from security teams and assessors alike.
Cloud-first strategy, data centre exit, divestment and acquisition integration. Track record leading the technology workstreams when organisations restructure — including separations for global PLCs.
Illustrative engagements — clients anonymised. Specifics available on request.
Designed and delivered an enterprise AVD platform for a global workforce, replacing legacy Citrix infrastructure. Built on a CAF-aligned landing zone with regional onboarding, governance and security controls baked in from the start.
Technical lead for the platform underpinning one of Europe's largest defence estates. Owned high-level designs and the architecture team, with hardening and assurance held to CESG-aligned standards throughout.
Architected a Microsoft 365 remote learning platform for one of the UK's largest education estates during the pandemic. Identity, Intune, conditional access and DLP delivered as one integrated stack — under serious time pressure.
Peak Delivery is led by Stephen Allison, a senior Solutions Architect with more than twenty years' experience across financial services, defence, utilities, education and the public sector.
The work spans the lifecycle: Azure and AWS landing zones, AVD and modern workplace, hybrid infrastructure, Zero Trust networking, and the M&A and divestment programmes where architecture has to hold up under commercial as well as technical pressure.
Every engagement is led directly. No juniors fronted by senior names, no offshore handoffs — you get the architect in the room, on the call, and at the whiteboard.
Whether you're scoping a landing zone, planning an AVD rollout, navigating an M&A separation, or wrestling with a cloud programme that's stalled — drop a line. Initial conversations are confidential and obligation-free.
