MySQL · Percona · MariaDBMySQL, tuned, replicated, and never down.
In short: MySQL is the world's most widely used open-source relational database, owned by Oracle and accessed via SQL. Its default InnoDB engine provides ACID transactions, and it scales through replication and InnoDB Cluster. Percona Server is a drop-in MySQL distribution with extra performance, observability, and operational tooling.
Expert MySQL & Percona consulting — performance tuning, high availability, migration, and 24/7 DBA support from one specialist team. Median 10× query speedup, contractual 99.99% uptime SLA.

What we do
Full-spectrum MySQL engineering
From a 4-second query to a zero-downtime cutover — we've seen it, fixed it, and documented the runbook.
Performance Tuning
InnoDB buffer-pool sizing, query and index optimization, slow-query analysis — median 10× speedup.
High Availability
InnoDB Cluster, Group Replication, ProxySQL routing, and Orchestrator for sub-15-second failover.
Replication & Scaling
GTID replication, read-replica fan-out, Vitess sharding, and InnoDB Cluster for horizontal scale.
Percona Expertise
Percona Server, XtraDB Cluster, XtraBackup, PMM observability, and the Percona Toolkit.
Migration & Cloud
Oracle/SQL Server → MySQL, plus RDS, Aurora, and Cloud SQL migrations with zero-downtime cutover.
Security & Compliance
TLS, at-rest encryption, audit logging, least-privilege roles — hardened for SOC 2, HIPAA, PCI DSS.
Performance tuning
From slow to blazing fast
in days, not months
We don't guess — we instrument. Slow-query log, EXPLAIN ANALYZE, pt-query-digest, and Performance Schema drive a median 10× query improvement.

Replica Lag
High availability
Always on. Engineered that way.
InnoDB Cluster with Group Replication, ProxySQL routing, and Orchestrator-managed topologies — tested with quarterly failover drills. Real 99.99% uptime, not a theoretical SLA.
Incident response
A P1 page, handled in under 15 minutes.
When replica lag or a runaway query brings production down, a named engineer responds — not a ticket queue. Runbook-driven fixes applied online, with a blameless postmortem after.
Replica lag > 60s — read traffic degrading
Named DBA in under 15 min, not a ticket queue
Runaway full-table scan on orders (no index)
pt-online-schema-change added covering index, online
Lag cleared, p99 4.2s → 180ms — total 14 min
Pre-Migration Assessment
Oracle / on-prem → MySQL 8.0
Estimated cutover window: < 10 minutes
Migration
Move to MySQL without the downtime
Oracle and SQL Server → MySQL, or self-hosted → RDS/Aurora. We pre-validate schema and charset, load with mydumper or AWS DMS, replicate the binlog to zero lag, and cut over in a sub-10-minute window.

FAQ
Common questions
Do you provide 24/7 MySQL support?
Yes. Our SRE team offers round-the-clock monitoring, alerting, and incident response with agreed SLAs — P1 under 15 minutes.
Can you help with zero-downtime MySQL upgrades?
We design replica-based or blue/green cutovers with validation and rollback plans to avoid downtime, including major-version jumps onto MySQL 8.4 LTS and legacy/EOL migrations off MySQL 5.7 and 8.0.
What MySQL distributions do you support?
Oracle MySQL, Percona Server, and MariaDB — self-hosted and managed (Amazon RDS, Aurora, Cloud SQL, Azure Flexible Server).
How do you tune slow MySQL queries?
We use the slow-query log, EXPLAIN/EXPLAIN ANALYZE, pt-query-digest, and Performance Schema to find the worst offenders, then fix them via indexing, query rewrites, and InnoDB configuration.

Compare with Other Databases
JusDB operates production fleets across most major engines. If you're weighing alternatives, here are the most common ones our customers compare against.
PostgreSQL
If you're evaluating a move off Oracle or want richer JSON / window-function support than MySQL's stock optimizer offers, PostgreSQL is the usual next stop.
MongoDB
Teams whose schema is outgrowing relational rigidity (deeply nested documents, polymorphic event payloads) typically pair MySQL with MongoDB for the unstructured surface.
SQL Server
Common when an enterprise stack already runs Windows / .NET and the procurement path to SQL Server licenses is easier than a new MySQL deployment.
TiDB
MySQL-wire-compatible with horizontal scalability — the natural escape hatch when a sharded MySQL fleet starts costing more than it earns.
