The most common causes of cloud overspend in data and the techniques to cut it without losing performance: sizing, formats, queries and frequencies.
The cloud makes scaling easy, but also makes overspending easy without noticing. In data projects — compute- and storage-intensive — overspend is especially easy to accumulate. The good news: much of it is avoidable.
Cloud cost optimisation in data is the set of practices to reduce infrastructure spend without sacrificing performance or reliability, matching consumption to what the business actually needs.
Overspend is not eliminated once and for all: workloads change, data grows and new inefficiencies appear. In a managed service, this watch and adjustment is part of the operation, so each process consumes the minimum necessary.
Optimisation is not a one-off cleanup but a continuous cycle, or savings erode as workloads grow.
Cloud overspend in data comes from idle capacity, inefficient queries, heavy formats and excessive refresh frequencies — most of it avoidable. Right-sizing, query and format optimisation and right frequencies cut the bill without losing performance, but only if done continuously.
Idle capacity, inefficient queries, heavy formats and excessive refresh frequencies. Most is avoidable with optimisation.
No. Done well, it reduces spend while maintaining or improving performance, matching consumption to real need.
No. It must be continuous, because workloads and data change. In a managed service it is part of the operation.
Right-sizing and shutting down idle resources, optimising queries and partitioning, using compressed columnar formats, and adjusting refresh frequency.
It varies, but removing idle capacity and tuning queries and formats often cuts a significant share of the data cloud bill.
The provider, continuously, as part of the operation — so each process consumes the minimum necessary without you watching it.
