Zero-Disruption Migrations: A 90-Day Blueprint for Moving Off AWS

Your engineering team's most expensive hours aren't spent building features—they're spent managing cloud costs that spiral 28% year-over-year while delivering 27% waste (Flexera 2025).

The numbers tell a stark story: 84% of organisations cite cloud spend management as their top infrastructure challenge, while 54% avoid migration due to complexity fears. Meanwhile, 57% struggle to hire the IT talent needed to solve these problems internally.

The result? A vicious cycle where costs climb, engineering velocity drops, and solutions feel too risky to attempt. Traditional migrations freeze feature development for months— creating a cure that seems worse than the disease.

Here's our 90-day blueprint that breaks this cycle: protect your roadmap while systematically reclaiming up to 50% of your cloud budget with fixed monthly costs.

The Migration Paradox¶

Most companies face an impossible choice: accept spiraling costs or risk months of frozen development during migration. This false dilemma exists because traditional approaches treat infrastructure and product development as competing priorities.

The hidden cost of inaction: For a company spending £2M annually on cloud, 27% waste equals £540K—enough to fund multiple senior engineers. But the real cost is opportunity: while your team debugs cost allocation, competitors ship faster.

Why migrations fail: 46% of cloud projects are deemed too complex to manage internally (CNCF 2024), yet companies attempt them without expert guidance, leading to timeline overruns and feature freezes.

Our approach flips this script by running migration tasks parallel to sprints rather than replacing them.

Our Approach¶

Our blueprint runs alongside your existing sprints, never replacing them:

    Cut-over & Optimise  :m4, 2025-03-02, 30d

The key insight: Migration tasks pair with sprints rather than replacing them. Your product team maintains velocity while our infrastructure specialists handle the technical heavy lifting.

Cost predictability: Unlike cloud bills that fluctuate with usage spikes, you get a fixed monthly invoice that makes budgeting straightforward. No more surprise charges or complex cost allocation—just predictable infrastructure costs that scale with your business, not your traffic patterns.

Results & Proof¶

IoT Solar Water Pump Company: Migrated from Google Cloud to bare-metal infrastructure, stabilising costs for two years while cutting request latency by 50%. The client shifted focus from managing data pipelines to core business expansion and product development.

"Working with Lithus has been a game-changer. Their support has been rock-solid. They've stabilised our costs, halved our latencies, and freed up our engineers. We've entrusted them with multiple ventures over the years, and they've always been a reliable and trusted partner in our work."
— Toby Hammond, CEO, Futurepump

Government & NGO Projects Client: Deployed flexible infrastructure with step-up cost structure aligned to funding cycles. Established seamless continuous deployment for multidisciplinary teams (front-end, back-end, hardware) while avoiding third-party software costs through internal business software deployment.

"Having Lithus onboard has been invaluable. Their expertise and flexibility have given us the ability to tackle increasingly complex projects without having to hire. We punch above our weight, in no small part because of Lithus."
— Samson Sahmland-Bowling, CEO, Open Energy Labs

The numbers across our client portfolio demonstrate consistent, measurable impact. Cost reduction averages 30-50% savings, with no up-front migration fees. Performance improvements are equally dramatic, with 50% latency reduction being typical as workloads move from shared cloud infrastructure to dedicated bare-metal resources.

Beyond the immediate financial and technical gains, the broader business impact proves even more valuable. Engineering teams report being freed from constant infrastructure firefighting, allowing them to focus on core product development and innovation. This operational relief translates directly into business growth, with clients confidently expanding into new markets and launching ambitious projects they previously couldn't resource properly.

The consistency of these outcomes reflects our systematic approach: we don't just migrate infrastructure, we transform how companies think about and manage their technical foundation.
