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.

Qu'est-ce que la diffusion en continu et pourquoi est-elle importante ?

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.

Going serverless

Creating and running Lambda functions

Serverless vs servers

Lambda function components

Reading data from S3 based on an event

Your first live lambda!

Adding a lambda layer

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

Qu'est-ce qui alimente les systèmes que nous utilisons tous les jours sans nous en rendre compte, comme la détection des fraudes qui garantit la sécurité de nos transactions ou les feux de signalisation qui assurent la fluidité du trafic ? La réponse est le streaming data (données générées en continu par différentes sources) et les technologies sans serveur, comme Amazon Kinesis et AWS Lambda.
<br /> <br />
Dans ce cours, vous apprendrez à tirer parti de ces puissantes technologies en aidant un ingénieur en données fictif nommé Cody. Votre objectif est de l'aider à collecter des données en temps réel à partir de véhicules appartenant à la ville, d'analyser ces données et d'envoyer des alertes pertinentes, comme des avertissements de vitesse, aux conducteurs. En utilisant Amazon Kinesis et Firehose, vous apprendrez à ingérer des données provenant de millions de sources avant d'utiliser Kinesis Analytics pour analyser les données au fur et à mesure qu'elles se déplacent dans le flux. Vous créerez également des fonctions sans serveur dans AWS Lambda qui déclencheront conditionnellement des actions en fonction des données reçues. À la fin de cette formation, vous saurez comment créer des tableaux de bord ElasticSearch en direct avec AWS QuickSight et CloudWatch et, je l'espère, aider Cody à mener à bien son ambitieux projet.

D'autres services AWS (entités de confiance) peuvent porter un chapeau pour obtenir des autorisations supplémentaires.

NEVER peut-il avoir un AWS ACCESS KEY et SECRET

Les politiques d'autorisation leur sont attribuées à l'aide de IAM
