Database solutions and cloud migration
Faster queries, safer data, and a cloud move without the weekend outage.
Database architecture, performance tuning and migration to AWS or Google Cloud, for PostgreSQL, MySQL, SQL Server and warehouse platforms.
The problem
Slow queries, a server under someone's desk, backups nobody has tested, and an application that cannot grow because the database cannot keep up.
Moving to the cloud or a new database is risky if it is done as one big switch. It needs a plan that keeps the business running throughout.
What we build
- Database architecture and schema design for new applications
- Performance tuning: indexes, query rewrites, partitioning, caching
- Migrations from on-premise servers to AWS or Google Cloud
- Migrations between engines, such as SQL Server or MySQL to PostgreSQL
- Backup, recovery and high-availability setups that are tested
How it works
The current system is profiled, a target is designed, data is replicated in parallel, validated, and cut over with a rollback plan.
- Step 1ProfileMeasure workload, slow queries, data volume and dependencies.
- Step 2Design targetChoose engine, sizing and architecture; estimate running costs.
- Step 3ReplicateCopy and sync data to the target while the old system runs.
- Step 4ValidateCompare row counts, checksums and application behaviour.
- Step 5Cut overSwitch during a planned window, with a tested rollback.
Deliverables
- Assessment and target architecture
- Migration plan with rollback
- Migrated and validated database
- Monitoring, backup and recovery runbook
Typical stack
- SQL
- Google Cloud
- Python

Questions
Will there be downtime?
Most migrations need a short cut-over window. We plan it for your quietest hours and rehearse it beforehand.
Can you help with running costs?
Yes. Right-sizing instances, storage tiers and query optimisation often lower cloud bills noticeably.
