Let&#x27;s say you have a CMS which pushes content to your site. You also want to make the whole site searchable, so you index your content into (e.g) Elasticsearch. Kafka is great for this because you can put the content onto Kafka&#x27;s message queue and then have a service reading from it which then put&#x27;s it into Elasticsearch. It scales well, too. So let&#x27;s say your site takes off and you have hundreds of articles published a day (not to mention updates, deletions etc) - these events can all be sent to kafka and it will maintain the order as well as still be fast. You can also have many many services reading (consuming) from it simultaneously and it will handle it nicely.<p>Basically, if you want to get data from one place to another and care about order, Kafka is a good solution. It acts as a middleman between services.
