MySQL Database Experts
Enterprise MySQL consulting, modernization, and long-term stewardship for organizations running mission-critical MySQL workloads.
PALADEM’s MySQL database experts help engineering teams plan, migrate, tune, and sustain the MySQL systems their applications depend on. Whether you are working through a long-delayed MySQL 5.7 to 8.0 or 8.4 migration, moving off a self-managed instance to RDS, Aurora, or Cloud SQL, or trying to stabilize a replication topology that keeps drifting, our MySQL experts deliver work that holds up under real operational scrutiny.
Why Choose MySQL?
MySQL remains one of the most widely deployed relational databases in the world, and in 2026 its core case is straightforward: it is free, open source, very broadly supported by tooling and hosting providers, and forgiving enough for non-DBA teams to run at small and mid scale. The modern MySQL 8.0 and 8.4 LTS lines have closed most of the historical feature gap with other relational engines, adding a proper data dictionary, window functions, common table expressions, and a workable JSON implementation. Managed offerings like Amazon RDS, Aurora MySQL-compatible, Google Cloud SQL, and Azure Database for MySQL make it realistic to run production workloads without a dedicated DBA. MySQL is a particularly good fit for teams that value ecosystem maturity, predictable operations, and a large pool of people who already know how to work with it.
Our MySQL Services
MySQL Schema Design & Application Development
We design MySQL schemas and data-access layers for new applications, working from the data model outward. Our work targets current MySQL 8.0 or 8.4 LTS with sensible defaults for character set, collation, indexing, and InnoDB configuration, integrated with whatever application stack your organization runs. Every database we help deliver is shaped for the ten-year view: room to evolve, clear naming, and a schema that future engineers can actually read. This complements our broader database administration services.
MySQL Consulting & Architecture
Our MySQL consulting experts advise engineering leaders on the decisions that are hardest to reverse: MySQL versus MariaDB versus Aurora MySQL-compatible, self-managed versus managed service, replication topology, sharding thresholds, and backup strategy. We review existing deployments, identify operational and architectural risk, and deliver written recommendations your team can act on. When it helps, we work alongside your engineers to implement the patterns rather than only describing them.
Performance Optimization
Slow MySQL is usually diagnosable. We capture representative workloads with the slow query log and pt-query-digest, read EXPLAIN and ANALYZE output, and prioritize fixes by total impact. Common levers include missing or redundant indexes, join order, implicit charset conversions, bad SELECT patterns, long-running transactions, InnoDB buffer pool sizing, and replication-lag sources that turn up as stale-read complaints on the application side.
Legacy MySQL Modernization
We run staged MySQL modernizations: MySQL 5.7 to 8.0 and 8.4 LTS upgrades, MyISAM to InnoDB conversions, utf8 to utf8mb4 charset migrations, and self-managed to RDS, Aurora, or Cloud SQL moves. Our approach uses logical or physical replication for cutover, rehearsed runbooks, reconciled data verification, and a rollback plan at every step. The database remains shippable throughout the engagement. No big-bang rewrites and no undocumented cutovers.
MySQL Support & Maintenance
We provide ongoing support for production MySQL environments, including version patching, parameter tuning, backup and point-in-time recovery validation, restore drills, replication health, security review, and capacity planning. Our maintenance engagements are sized to the real surface area of your database footprint and keep your platform current with the LTS release cadence rather than letting it drift into another EOL event.
Why PALADEM?
- Built for Enterprise MySQL. Our MySQL work targets long-lived, mission-critical databases where durability, recoverability, and predictable performance matter more than chasing the newest feature.
- US-Based Architecture, Global Delivery. Senior US architects lead every engagement, supported by a global engineering team for efficient, cost-effective delivery. See our full services for how we structure engagements.
- Software Stewardship Approach. Every MySQL engagement is guided by our Software Stewardship Framework™, which treats your database as a long-lived asset to be cared for across all eight stewardship pillars rather than a one-time migration.

Learn moreFrequently Asked Questions
MySQL 5.7 hit end of life in October 2023. What is actually at stake if we have not migrated yet?
Running a post-EOL database means no more security patches from Oracle, growing distance from supported client libraries and managed-service runtimes, and rising friction every time a dependency or OS is upgraded. The business risk is less about any single vulnerability and more about accumulating exposure on a system that is almost always inside the security perimeter. A staged migration to MySQL 8.0 LTS or 8.4 LTS, with schema and query compatibility review up front, is a well-understood engagement. We assess first, sequence the work, and keep the application shippable throughout.
MySQL, MariaDB, or Aurora MySQL-compatible: which do you recommend and when?
The right answer depends on where the workload lives and how far the team has already drifted. Oracle MySQL 8.0 or 8.4 LTS is the default for teams that want to stay on the upstream fork, particularly on managed services like RDS or Cloud SQL. Aurora MySQL-compatible is a strong choice for large cloud workloads that benefit from its storage and replication architecture, with the tradeoff of AWS lock-in and some behavioral differences. MariaDB has meaningfully diverged from upstream MySQL, so it is a deliberate choice rather than a drop-in, and upgrade paths between MariaDB and MySQL are no longer seamless. We size the decision to the application and the operational model, not to a preference.
How do you approach moving a self-managed MySQL instance to RDS, Aurora, or Cloud SQL?
Managed-service migrations start with a compatibility and configuration review: engine version, character set, authentication plugin, parameter group deltas, and any features in use that the target service restricts. From there we plan the cutover: logical or physical replication from source to target, a data reconciliation step, a rehearsed cutover window, and a rollback plan. We also revisit backup, point-in-time recovery, and monitoring on the new platform rather than assuming the managed service gets it right by default. The goal is a clean cutover with documented runbooks, not a move that quietly degrades operational posture.
We are still on the utf8 charset. What is involved in migrating to utf8mb4?
The historical utf8 charset in MySQL is only three-byte UTF-8, which cannot store four-byte characters like most emoji or several Asian-language glyphs. Migrating to utf8mb4 gives you full Unicode and is the modern default, but it touches schema, connection settings, collation choices, and index key lengths. The migration needs a schema audit for oversized indexes, a coordinated change to server, database, table, and column defaults, and an application-side review of connection charset handling. We run it as a staged conversion with verification queries at each step, not a single big ALTER.
How do you tune slow MySQL queries and unstable replication?
Tuning work starts with evidence. On the query side we capture a representative workload with the slow query log and pt-query-digest, read EXPLAIN and ANALYZE output, and prioritize fixes by total impact rather than worst single query. Common levers are missing or redundant indexes, join order, implicit conversions, and bad SELECT patterns from the application. On the replication side we look at topology, binlog format, replica lag sources, long-running transactions, and whether the read pattern belongs on a replica at all. The deliverable is a prioritized plan with measured before and after numbers and a short list of queries the team can own going forward.
