+When using [Akka Streams](/languages-and-frameworks/akka-streams.html) to build
+reactive data transformation services you usually need to connect to several
+different services like FTP, S3 buckets, AMQP brokers or different databases.
+
+[Alpakka](https://developer.lightbend.com/docs/alpakka/current/) provides
+integration building blocks for Akka Streams to access these services in a
+reactive fashion and also contains transformations for working with XML, CSV or
+JSON structured data.
+
+Akka Streams and Alpakka combined enables us to build small reactive
+integration services with minimal resource consumption and good performance and
+are good alternative to bigger ESB solutions or integration tools.
