MySQL is an open-source relational database management system (RDBMS), developed by Oracle, and one of the most widely used in the world. It uses the SQL language to store, query, and update data and is the foundation of a large portion of web, e-commerce, and management software applications.

It offers ACID transactions with the InnoDB engine, replication for high availability and read scalability, and a rich ecosystem of tools. Its MySQL expertise also applies to MariaDB and Percona Server, which maintain broad compatibility.

We work on four levels. Queries : EXPLAIN and the slow query log identify the most expensive operations and full table scans to eliminate. Indexes : they must cover frequent searches without overloading writes.

Schema : Correct data types and load-appropriate structures reduce space and access times. Server configuration : InnoDB buffer pools, logs, connections , and I/O must be sized based on the hardware and actual load.

Every modification must be measured before and after: this is the method we apply in every tuning intervention.

Because the database is often the most critical component of the infrastructure: a slowdown or data loss immediately translates into service disruptions and costs.

Professional management ensures stable performance, verified backups, timely security updates, and a proven disaster recovery plan. And when something goes wrong, the cause is identified and resolved promptly, not by trial and error.

Additionally, an experienced DBA designs the database for growth: more data and more users without compromising performance and security.

MySQL is developed by Oracle, with an open source Community edition and a paid Enterprise edition that adds tools and commercial support.

Percona Server for MySQL is a MySQL-compatible distribution that adds diagnostics, security, and performance management features available in MySQL's Enterprise edition only.

MariaDB was born as a fork of MySQL by the project's original developers and has gone its own way, with specific features and storage engines: compatibility with MySQL remains broad but not complete.

The choice depends on the applications, versions in use, high availability tools and budget: we help you evaluate it with concrete data.

With a faster and more stable database, infrastructure costs under control and the certainty of being able to recover data in the event of a failure.

We address performance optimization, troubleshooting, high availability, migrations, and disaster recovery, both through targeted interventions and ongoing management.

The most common signs are four: increasing response times , with queries or pages becoming slow; instability , with crashes, reboots, or connection errors; high resource consumption , with CPU, memory, or disk constantly under pressure; inconsistent data , with replicas lagging or becoming misaligned.

The causes could be missing indexes, inefficient queries, an unsuitable configuration for the load, or replication issues. An initial analysis allows you to understand where to intervene and what priorities to set.

Both. For companies that already have an in-house team, we offer targeted interventions for individual issues: incident resolution, tuning, migration, and disaster recovery planning.

For those requiring continuous support, we offer complete database management, either independently or alongside your staff, with defined monitoring, maintenance, and SLAs.

The fee is monthly and there are no long-term commitments: you can interrupt the service at any time with 30 days' notice, so you can manage the transition without disruptions.

Yes. Managed Server provides its services in compliance with the General Data Protection Regulation (EU Regulation 2016/679). Data relating to your infrastructure and support requests are processed within the European Union and deleted within 30 days of completion of the services.

We apply the principles of privacy by design and privacy by default, with encryption, access controls, and periodic review of procedures. For databases containing personal data, we help you properly configure access, encryption, and retention.

For large databases, we perform hot physical backups with Percona XtraBackup or Mariabackup, without disrupting the service, along with logical dumps with mysqldump or mydumper when portability is required. We also retain binary logs, allowing you to restore the database to a precise point in time before a failure or accidental deletion.

Copies are stored off the production server, with an agreed-upon retention policy, and verified with periodic, documented recovery tests.

Yes. We configure primary-replica replication, even with GTID, to distribute reads and have an always-updated copy ready to take over, and multi-primary clusters with Galera, MariaDB Galera Cluster, or Percona XtraDB Cluster where you need to write to multiple nodes.

We complete the architecture with replication lag monitoring and a proxy such as ProxySQL or HAProxy to route connections and manage failover, and we document procedures to follow in the event of a node failure.
