Günlük hayatta fark etmeden kullandığımız sistemleri — örneğin işlemlerimizi güvende tutan dolandırıcılık tespiti ya da trafiğin akışını düzenleyen trafik ışıkları — hangi teknoloji çalıştırıyor? Cevap: akış verileri (farklı kaynaklar tarafından sürekli üretilen veriler) ve Amazon Kinesis ile AWS Lambda gibi sunucusuz teknolojiler.
<br /> <br />
Bu derste, bu güçlü teknolojilerden nasıl yararlanacağını, kurgusal bir veri mühendisi olan Cody’e yardım ederek öğreneceksin. Amacın, şehir araçlarından gerçek zamanlı akış verisi toplamasına, bu veriyi analiz etmesine ve sürücülere hız uyarıları gibi ilgili bildirimler göndermesine yardımcı olmak. Amazon Kinesis ve Firehose kullanarak milyonlarca kaynaktan veri almayı; ardından veri akış içindeyken Kinesis Analytics ile analiz etmeyi öğreneceksin. AWS Lambda’da, gelen veriye göre koşullu olarak eylem tetikleyen sunucusuz fonksiyonlar da çalıştıracaksın. Eğitimin sonunda AWS QuickSight ve CloudWatch ile canlı ElasticSearch panoları oluşturmayı bilecek — ve umarız Cody’nin iddialı projesini tamamlamasına yardım etmiş olacaksın.
