Hey @PanasonicIndia One month back I raised the service request and one of executive came and inserting bathroom cleaning acid into washing machine. Entire system was damaged. after that simple close my request. @PanasonicIndia kindly look into it.

[SIVA KUMAR KOONA @KOONASIVA]

Hi @airtelindia Team
Recently I raised more than 3 complaints. Without a proper solution, you people just closed the tickets.
Also, your service engineers behave very unknowingly.

@SwiggyInstamart
Guys, be careful. @SwiggyInstamart delivery partners cheat the customers. They updated the status as delivered without delivering the product, and in the call, they used abusive words.

Becoming AWS Data Engineer (Quick Guide) 📄

There are 100s of services available on Amazon Web Services, the thing is you don't need to learn all of them.

You need to focus on 10-20 services that you might use as a Data Engineer and services for other work (networking/access management)

📈 AWS Services for Data Engineers:

✅ Simple Storage Service (S3):
It is an object storage (you can store anything) basically, the center of your work, all of the data you will get will be stored here for future processing.

✅ AWS Glue:
Want to write ETL (Extract, Transform, Load) jobs in Python/Spark without worrying about servers? Glue is a serverless service where you just need to focus on writing your code and everything will be taken care of by AWS

✅ Amazon Redshift:
So you processed data and wrote the ETL script, where to load it? Yes! Data Warehouse. Amazon Redshift is a fully managed data warehouse service that makes it simple to analyze all your data using standard SQL and your preferred business intelligence (BI) tools.

✅ Amazon EMR (Elastic MapReduce):
Maybe you already have your processing scripts on on-premise servers written in Hadoop/Spark and want to migrate to a similar system then EMR is the way to go.

It is a managed big data platform that makes it easy to process large amounts of data using open-source data processing frameworks like Apache Hadoop and Apache Spark.

✅ AWS Lambda:
Want to run quick scripts on specific times/triggers/events? Lambda is your best friend!

AWS Lambda is a serverless computing service that enables you to run your code without managing servers. This service can be used to run data engineering workflows and transform data in real time.

✅ Amazon Athena:
Why load data on Data Warehouse, when you can just direct run SQL query on top of actual files? Athena is an ad-hoc query interface that you can use for SQL queries directly on top of files stored on S3 buckets

✅ Kinesis:
Want to process real-time data, analyze it, and store it? Kinesis is used for this type of work, just like Apache Kafka, you can process real-time data using Kinesis.

✅ DMS (Data Migration Service):
I spent my early data engineering days working on migration projects and DMS makes your life so much easier.

There are many more services you can focus on such as EC2, IAM, VPC, Batch, Sagemaker, etc...

If you want to learn all of these services by building a project then check below👇🏻

Everyone should own a faceless Youtube channel that earns $5000/m

Sadly, 99% people think this takes years to achieve

Here’s how to do it in the next 30 days:
