OpenDBWorks

Cloud MSP · Data Migration · Open-source DB

Cloud and databases,
owned by one team.

Multi-cloud managed services, data migration from commercial databases to open source and the cloud, and open-source database installation, support and tuning. Backed by 27+ years of hands-on DBA experience, from infrastructure to data under one standard.

Core businesses

Three core businesses

One team connects infrastructure, migration and databases, so you do not have to split accountability.

Databases

Four open-source engines, one operating standard

Each engine has its own HA model, backup tooling and tuning levers. We follow engine-specific best practice while keeping one standard for documentation, health checks and change management.

RDBMS

PostgreSQL

Streaming and logical replication, Patroni failover, PgBouncer pooling, WAL-based PITR.

MySQL

InnoDB tuning, Group Replication and InnoDB Cluster, ProxySQL, 8.0 → 8.4 LTS upgrades.

Services

The full database lifecycle

Engage us for a single project phase, or keep us on an ongoing maintenance agreement.

Architecture & installation

Topologies sized to your workload and availability goals, OS/storage/parameter standards, automated installs.

High availability & replication

Automatic failover, read scaling, disaster-recovery sites and switchover rehearsals.

Backup, recovery & PITR

Backup design that starts from your RPO/RTO, with scheduled restore tests.

Performance tuning

Evidence-based work on wait events, execution plans, indexes, parameters and schema.

Monitoring & alerting

Metrics, thresholds and alerts with PMM, pg_stat_statements, Telegraf and Grafana.

Upgrades & migration

Major-version upgrades and Oracle/Tibero → PostgreSQL/MySQL moves (ora2pg and more).

All servicesSupport plans

Migration

From commercial databases to open source — verifiably

Drawing on Oracle and Tibero operations experience, we run assessment → schema/code conversion → data migration → validation → cutover.

  1. Assess

    Inventory of objects, PL/SQL and SQL patterns with an effort report (e.g. an ora2pg report).

  2. Convert

    Types, sequences, packages and triggers converted; application SQL changes scoped.

  3. Migrate & validate

    Full load plus change sync; row counts, checksums and business-query results compared.

  4. Cut over

    Cutover and rollback plan proven in rehearsal, followed by stabilisation support.

How we work

We start with a diagnosis and finish with documentation

  1. Assess

    Collect versions, topology, resources, incident history and metrics; rank risks and priorities.

  2. Design & agree

    Agree target architecture, scope, change procedure and rollback criteria in writing.

  3. Build & improve

    Validate on staging, apply to production, confirm the effect with before/after metrics.

  4. Hand over & operate

    Deliver runbooks, checklists and incident procedures; continue under maintenance if you wish.

Why OpenDB Works

Why OpenDB Works

27+ years as DBAs

Hands-on operation of Oracle, MySQL/Aurora, PostgreSQL, MariaDB, Tibero and more.

Evidence-based tuning

We explain with metrics, plans and before/after comparisons — not hunches.

Everything documented

Designs, runbooks and checklists are deliverables, so knowledge stays with your team.

Safe change

No production change without staging validation, an approved window and a rollback plan.

Shall we start by reviewing your cloud and databases as they are today?

Tell us your clouds, database versions, topology and concerns, and we will propose an assessment scope and approach.
