How to choose: answering the main questions
What is critical for ABS and processing systems?
Disk latency and reliability: NVMe in RAID10, ECC, dual power supplies, DBMS clustering. Peak loads at the end of the day and reporting dates are factored into the calculation from the start.
Redundant data center?
The financial sector standard is an active-passive setup in a different building/city: database replication with RPO measured in seconds. We design site pairs and test failover procedures.
Encryption and auditing?
SED drives with hardware encryption, TPM, boot integrity control, and IPMI logs. We prepare schemes and regulations for regulatory inspections and internal audits.
