The core Elastic product: search
When you think of search, you probably think about Google. But on the engineering side, developers need to search through a lot of stuff, especially logs of what’s happening on their servers and apps. Elasticsearch, and the managed service for it that Elastic (the company) provides, is a database and search engine for doing just that.
Elasticsearch’s primary use cases revolve around things that commonly need, well, search. One big theme centers around infrastructure management, but teams also use it for security and even user facing search engines. It’s also most commonly used with what’s called the ELK stack, which is a series of adjacent tools that help you use Elasticsearch like Kibana and Logstash.
Another database? Some taxonomy
Yet another database !? Yes, my dear readers, another database. But Elasticsearch isn’t like other databases; it’s use case specific, meaning it was designed for doing specific things with particular types of data...
