This is the fifth part in the DevOps 101 series and it’s time to talk about automation. Before we get into it, I just want to recap what DevOps is. Microsoft’s Donovan Brown sums it up nicely in a single sentence: DevOps is the union of people, process, and products to enable continuous delivery of value to our end users. The important thing to remember here is the order in which he talks: people, process, and products. That’s the way DevOps works.

The demand for cloud services is rising. Databases have been popular tools for a long time. However, the landscape is changing, with cloud databases becoming increasingly popular.

MongoDB is one of the most popular NoSQL databases in the world, used by millions of developers to store application metrics from e-commerce transactions to user logins. The MongoDB Enterprise plugin for Grafana — which is available for users with a Grafana Cloud account or with a Grafana Enterprise license — unlocks all of the data stored in MongoDB as well as diagnostic metrics for monitoring MongoDB itself for visualization, exploration, and alerting.

The enterprise data warehouse (EDW) provides access to business data stored in a denormalized structure called a star schema, which makes it easy to analyze, visualize, and forecast essential business metrics. Business intelligence (BI) reporting makes use of the data warehouse for real-time self-service dashboards, custom visualizations, data marts, decision-making reports, and machine learning (ML).

We need to remove a vmstorage node from VictoriaMetrics cluster gracefully. Every vmstorage node contains its own portion of data and removing the vmstorage node from the cluster creates gaps in the graph (because replication is out of scope).

As a long-time database consultant, I’ve fixed more blocking problems in database systems than I can count. Often this blocking has resulted from conflicts between processes needing to read rows while those rows are being modified.

A study from ManageForce estimated the cost of a database outage to be an average of $474,000 per hour. Long database outages are the result of poor design concerning high availability.
