Thanks to horizontal scalability and a large number of modules, Hadoop is a technology available for every enterprise, no matter the size, and capable of meeting even the most unusual requirements. The use of such modules as MapReduce, HDFS, Kafka, Spark and their implementations provided by Apache, Clouder, Hortonworks or Microsoft allows us to match a specific version of the software or service to the existing customer environment. Our extensive knowledge of Microsoft Azure and Amazon Web Services clouds allows us to look at Big Data not only as on-premise solutions but also as cloud services.
