AWS is the #1 cloud provider for open-source database hosting, and the go-to cloud for MySQL deployments. As organizations continue to migrate to the cloud, it’s important to get in front of performance issues, such as high latency, low throughput, and replication lag with higher distances between your users and cloud infrastructure. While many AWS users default to their managed database solution, Amazon RDS, there are alternatives available that can improve your MySQL performance on AWS t

Get a closer look with visualizations, metrics, and SLAs. Monitoring has always been a big part of solutions design. It is a continuous process of data collection about a system for the purpose of analyzing that system. Monitoring is usually done in an active way, with a tool pinging or probing a system in order to get responses. Those responses are then analyzed to better understand how the system is performing.
SQL Performance

There are multiple methods to look at poorly performing queries in SQL Server, notably Query Store, Extended Events, and dynamic management views (DMVs). Each option has pros and cons. Extended Events provides data about the individual execution of queries, while Query Store and the DMVs aggregate performance data. In order to use Query Store and Extended Events, you have to configure them in advance – either enabling Query Store for your database(s), or setting up an XE session and starting it.

We recently learned about a major breakthrough: Google says it has achieved “quantum supremacy” with a 53-qubit computer. I will steer clear of a lengthy explanation of quantum computing, which I’m not really competent to give. Quantum supremacy itself is a simple concept: it means performing a computation that could not be performed on a classical computer.
