FinOps and cost-governance rollout for a US SaaS scale-up

B2B SaaS company, Austin

Challenge
Cloud spend had grown 3x faster than revenue over two years with no one owning it; every engineering team provisioned its own resources with no tagging standard, so finance could not attribute cost to product lines when the board asked for unit economics.
Solution
We introduced a tagging standard enforced at deploy time, built cost dashboards broken out by product line and environment, and right-sized or decommissioned unused resources found in the audit. A monthly cost-review ritual now catches drift before it compounds.
Results
  • Monthly cloud spend down 31% with no performance regression
  • 100% of resources tagged and attributable to a product line
  • Unit cost per active customer now tracked monthly for the board

Replatforming a high-street homewares retailer's online shop

High-street homewares retailer, UK

Challenge
The retailer's web shop ran on a heavily customised platform that had fallen two major versions behind. Page loads averaged over four seconds on mobile, promotions needed a developer to set up, and the Christmas peak had taken the site down twice in the previous two years.
Solution
We rebuilt the storefront as a headless front end on a composable commerce back end, migrated catalogue and order history, and moved hosting to a managed cloud platform with autoscaling. Merchandisers now run promotions themselves. We load-tested to three times the previous peak before cutover.
Results
  • Mobile page load down from 4.2 seconds to 1.3
  • First peak season handled with 0 minutes of downtime
  • Promotion set-up moved from developer tickets to 15 minutes in admin

Planning-applications portal for a district council

District council, South East England

Challenge
The council's public planning register ran on a server in the basement, fell over during busy consultations, and displayed documents in a way that residents found hard to search. Comments were submitted by email and copied into the case file by hand, which took a planning officer most of Monday.
Solution
We rebuilt the planning portal on a managed cloud platform with a searchable register, map-based browsing and a structured comment form that files directly against the application. Officers moderate comments from a queue; the old server was decommissioned after a three-month parallel run.
Results
  • Portal uptime during consultations at 99.9% over the first year
  • Comment handling reduced from most of a day to 45 minutes weekly
  • Public document searches up 3x with no increase in phone enquiries

Zero-downtime Azure migration for a Manchester scheduling SaaS

Workforce scheduling SaaS firm, Manchester

Challenge
The platform ran on two rented servers in a colocation facility. A disk failure had caused a nine-hour outage, customers were asking about resilience in procurement questionnaires, and the engineering team of six had no capacity to plan a migration while shipping features.
Solution
AGS designed an Azure landing zone with infrastructure as code, containerised the application and moved the database using replication so cut-over happened in a maintenance window of minutes. We ran two rehearsals, handed over runbooks and stayed on for hypercare for the first month.
Results
  • Cut-over completed with 4 minutes of planned downtime
  • Monthly hosting cost down 23% against colocation
  • Migration delivered in 9 weeks

FAQ

Cloud Ops & Migration: questions, answered.

How does AGS migrate us to the cloud without downtime?

AGS builds sequenced migration plans with a rollback path at every stage, so a move to AWS, Azure, or GCP doesn't become a weekend of firefighting. We map dependencies across every workload before touching one, move a low-risk workload first to prove the process, then tune once workloads have settled. Vantage Telecom migrated core billing with zero downtime.

What is a cloud migration rollback plan and why does it matter?

A rollback plan is a tested path back if a cutover doesn't go as planned. It matters because an unrecoverable migration is how downtime horror stories start. AGS defines cutover and rollback steps before moving anything, and proves the process on a low-risk workload first, so you're never committed without an exit.

How do you know which workloads are ready to move to the cloud?

We run a workload assessment that gives you a clear picture of what's cloud-ready and what needs re-architecture first. Dependency mapping and sequencing come before a single workload moves, so nothing migrates in the wrong order. That assessment shapes the sequenced move plan and the rollback steps defined for each stage.

Which cloud platforms does AGS migrate to?

AGS runs migrations to AWS, Azure, and GCP. The approach is the same across all three: map dependencies before touching a workload, sequence a move plan with cutover and rollback steps, prove it on a low-risk workload, then right-size and cost-tune once workloads have settled in. The goal is a migration you won't have to explain later.
