Cutting a Perth business's Azure storage bill by 60% with automated tiering
A Perth business was spending about $5,000 a month on Azure storage. We analysed how their data was actually being used and set up automated lifecycle rules to move ageing data down to cheaper access tiers — cutting the bill to roughly $2,000 a month, a saving of around $3,000 every month (~$36,000 a year) with nothing deleted and no change to how staff work.

The challenge
A Perth business was spending around $5,000 every month on Azure storage and asked us to bring the cost under control. Cloud storage bills creep up quietly: data lands in Azure's default 'Hot' access tier — priced for frequent access — and simply stays there long after anyone last opened it. Years of files, backups and logs were all sitting on the most expensive tier, whether they were used daily or hadn't been touched in years. The client wanted the spend cut without losing any data or disrupting how their team works.
What we did
We started by analysing how the data was actually being accessed — how much was live and in daily use versus how much was ageing and rarely, if ever, opened. Azure Blob Storage offers several access tiers priced for different access patterns: Hot (frequent access, most expensive to store), then Cool and Cold (progressively cheaper to store, for data accessed infrequently), and finally Archive (the cheapest storage of all, for data you almost never need to retrieve). Rather than move anything by hand, we configured automated lifecycle-management rules that tier data down based on how long it had gone without being modified: data untouched for 45 days moves to the Cool tier, data untouched for 180 days moves to the Cold tier, and data untouched for 2 years moves to the Archive tier. The rules run continuously in the background, so data keeps flowing to the right-priced tier as it ages, with no ongoing manual effort.
The outcome
The Azure storage bill dropped from around $5,000 a month to roughly $2,000 — a saving of about $3,000 every month, on the order of $36,000 a year — with no data deleted and no disruption to the business. Files staff use regularly stayed on fast, hot storage; only genuinely ageing data moved down to the cheaper tiers, and it can still be retrieved when needed (archived data takes longer to rehydrate, which is the trade-off for its very low storage cost). Because the lifecycle rules are automated, the saving is permanent and self-maintaining rather than a one-off clean-up — a good example of how a short, focused piece of cloud cost-optimisation work can pay for itself many times over.
