Was treibt die Systeme an, die wir jeden Tag benutzen, ohne es zu merken, wie z.B. die Betrugserkennung, die unsere Transaktionen sicher macht, oder die Verkehrssignale, die für einen reibungslosen Verkehrsfluss sorgen? Die Antwort sind Streaming-Daten (Daten, die kontinuierlich von verschiedenen Quellen erzeugt werden) und serverlose Technologien wie Amazon Kinesis und AWS Lambda.
<br /> <br />
In diesem Kurs lernst du, wie du diese leistungsstarken Technologien nutzen kannst, indem du einem fiktiven Dateningenieur namens Cody hilfst. Dein Ziel ist es, ihr dabei zu helfen, Echtzeit-Datenströme von stadteigenen Fahrzeugen zu sammeln, die Daten zu analysieren und relevante Warnungen wie Geschwindigkeitswarnungen an die Fahrer zu senden. Mit Amazon Kinesis und Firehose lernst du, wie du Daten aus Millionen von Quellen einlesen kannst, bevor du Kinesis Analytics nutzt, um die Daten zu analysieren, während sie sich durch den Stream bewegen. Du wirst auch serverlose Funktionen in AWS Lambda erstellen, die basierend auf den empfangenen Daten bedingte Aktionen auslösen. Am Ende dieser Schulung wirst du wissen, wie du mit AWS QuickSight und CloudWatch Live-Dashboards mit ElasticSearch erstellst - und hoffentlich Cody geholfen haben, ihr ehrgeiziges Projekt zu vollenden.
