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.

Analyzing streaming data

In this final chapter, you will discover how to monitor your stream's performance using logs, metrics, alarms and dashboards. You will use Elasticsearch and build your own Kibana dashboard.

Monitoring and visualizing streaming data

Apa yang menggerakkan sistem yang kita gunakan setiap hari tanpa kita sadari, seperti deteksi penipuan untuk menjaga keamanan transaksi atau lampu lalu lintas yang membuat arus kendaraan tetap lancar? Jawabannya adalah data streaming (data yang dihasilkan terus-menerus dari berbagai sumber) dan teknologi tanpa server—seperti Amazon Kinesis dan AWS Lambda.
<br /> <br />
Dalam kursus ini, Anda akan mempelajari cara memanfaatkan teknologi kuat tersebut dengan membantu seorang data engineer fiksi bernama Cody. Tujuan Anda adalah membantunya mengumpulkan data streaming waktu nyata dari kendaraan milik kota, menganalisis data tersebut, dan mengirim peringatan yang relevan seperti peringatan kecepatan kepada pengemudi. Dengan Amazon Kinesis dan Firehose, Anda akan belajar cara mengumpulkan data dari jutaan sumber sebelum menggunakan Kinesis Analytics untuk menganalisis data saat data mengalir dalam stream. Anda juga akan membuat fungsi tanpa server di AWS Lambda yang akan memicu tindakan secara kondisional berdasarkan data yang diterima. Pada akhir pelatihan ini Anda akan mengetahui cara membuat dasbor ElasticSearch langsung dengan AWS QuickSight dan CloudWatch—dan semoga membantu Cody menyelesaikan proyek ambisiusnya.
