MySQL and MariaDB are optimal open-source databases for most relational database workloads.
WE TAKE ON THE CHALLENGE
At ITD, we have developed applications and solutions for many clients through the platform that MySQL has to offer. Our team provides strategies from the start of your installation, operational support, and migration of your applications to the cloud. Additionally, we offer MySQL support services, 24/7 DBA services, use case analysis, requirements gathering, detailed deployment plans, capacity planning, and cluster design: MySQL NDB Cluster, Galera Cluster for MySQL, Amazon Aurora, and MariaDB Galera Cluster.
OUR SERVICES
MySQL is very easy to set up and run. However, there are certain best practices that database specialists are experts in, which developers often overlook. A classic example is establishing an appropriate backup strategy and performing regular testing. Our team of DBAs manages your MySQL databases 24/7/365. We combine industry best practices with our experience and integrate them with our various platforms. Additionally, ITD Consulting can provide reports on which servers comply with these best practices and which do not.
Moving your databases to a managed cloud service such as Oracle Cloud, Azure, or Google Cloud is a good idea. However, it’s essential to ask: How do you decide what to move based on your application needs and cost? At ITD Consulting, we monitor the performance of your MySQL database using metrics such as CPU, disk latency, network latency, and memory usage, along with features used to quickly identify which of your databases are "cloud-ready" based on the different capabilities of Oracle Cloud, Azure, and Google Cloud. In addition, a detailed report is created recommending how it should be implemented in the cloud and how much it will cost.

MYSQL NDB CLUSTER
NDB Cluster is the distributed database system underlying MySQL Cluster. It can be used independently of a MySQL server with users accessing the cluster through the NDB API (C++). "NDB" stands for Network Database.
From the MySQL server perspective, the NDB cluster s a storage engine for storing row tables.
MySQL Cluster uses the MySQL server to provide the following capabilities in addition to the Ndb Cluster: SQL analysis/optimization/execution capability. Connectors to applications via JDBC, ODBC, etc. Cross-table join mechanism. User authentication and authorization. Asynchronous data replication to other systems.
Galera Cluster for MySQL provides immediate data recovery, constant system activity, and scalability for your future growth.
True active multi-master cluster. Thanks to this feature, you can read and write on any node at any time. It also has synchronous replication, so there is no slave lag: no data is lost during node lock. This service is fully coupled, as all nodes share the same state. Divergent data between nodes is not allowed. Multiprocessing is a great feature that ensures better performance under any workload. It does not involve master-slave failover operations or the use of VIP. Hot Standby. Finally, there is no downtime measurement during failover, as the latter is not present in the service.
GALERA REPLICATION
Galera replication occurs at the time of transaction confirmation, by transmitting the transaction write set to the cluster for application. The client connects directly to the DBMS and experiences behavior close to native DBMS.
The basic difference between synchronous and asynchronous replication is that "synchronous" ensures that if changes occur in one node of the cluster, they occur in other nodes "synchronously." "Asynchronous" does not guarantee the delay between applying changes in the "master" node and propagating changes to the "slave" nodes. The delay can be short or long; it’s a matter of luck. This also implies that if the master node fails, some of the latest changes may be lost.
An additional benefit of Galera Cluster is the assurance of good cloud support. Automatic node provisioning makes scaling and elastic scaling operations simple. Galera Cluster has proven to have extremely good performance in the cloud, especially when using multiple instances of small nodes across multiple data centers: AWS zones or even in wide area networks.
