In this first chapter, you will learn about the differences between batch and stream processing, create your first stream, manage its permissions, write to it and read from it.

What is streaming and why does it matter?

Batch vs stream

Producers and destinations

Managing Firehose delivery streams

Getting ready for the first stream

Creating roles

IAM users vs. roles

Permissions practice

S3 bucket creation

Working with the Firehose delivery stream

Create your first Firehose stream

Writing to a Firehose stream

Reading Firehose data

Streaming in the cloud

The next step in your streaming data journey is learning how to use transformational lambda functions to go serverless. Through hands-on exercises, you will add lambda layers and trigger lambda functions on specific conditions.

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.
