Let's walk through the full steps to generate a new personal_rsa key for your personal projects (if it doesn't already exist), set up the SSH configuration for both accounts, and smoothly switch between them.

Step 1: Check for Existing SSH Keys

First, let's check if you already have a personal SSH key, such as personal_rsa or id_rsa.

Run this command to list the SSH keys in your ~/.ssh/ directory:

ls ~/.ssh/

To build a short demo for AWS Forecast, you’ll want to focus on the key steps involved in setting up, training, and generating predictions. Here's a simple guide to create a short demo:

1. Define the Scope of the Demo (5-10 minutes)

• Objective: Show how to upload historical data, train a model, and generate predictions using AWS Forecast.
• Example Use Case: Predict demand for a product based on historical sales data.

2. Prepare Your Data (1 minute)

• Use a simple time-series dataset (e.g., historical sales, demand data, or temperature).
• Format the dataset as CSV with columns such as timestamp, item_id, and demand.
• Make sure the dataset is in a format acceptable by AWS Forecast (e.g., Amazon S3 CSV file).

What is OpenSearch and Amazon OpenSearch Service

OpenSearch is a distributed, community-driven, Apache 2.0-licensed, 100% open-source search and analytics suite used for a broad set of use cases like real-time application monitoring, log analytics, and website search. OpenSearch provides a highly scalable system for providing fast access and response to large volumes of data with an integrated visualization tool, OpenSearch Dashboards, that makes it easy for users to explore their data. OpenSearch is powered by the Apache Lucene search library, and it supports a number of search and analytics capabilities such as k-nearest neighbors (KNN) search, SQL, Anomaly Detection, Machine Learning Commons, Trace Analytics, full-text search, and more.

Amazon OpenSearch Service is an AWS-managed service that lets you run and scale OpenSearch clusters without having to worry about managing, monitoring, and maintaining your infrastructure, or having to build in-depth expertise in operating OpenSearch clusters

AWS Certified Data Engineer - Associate DEA-C01: Key Concepts and Best Practices

Passing the AWS Certified Data Engineer – Associate DEA-C01 exam is a significant achievement. As you transition from studying to applying your knowledge, it’s essential to understand and implement best practices across various AWS services. This blog will explore critical areas, including change data capture (CDC), performance tuning, access control, and more.

Implementing CDC-Based Upserts in a Data Lake

Efficiently managing data lakes is crucial for scalable analytics. Using Apache Iceberg with AWS Glue, you can implement a CDC-based upsert mechanism, ensuring your data lake remains up-to-date with minimal performance overhead. This approach supports efficient query performance by avoiding full data scans and focusing on incremental changes. For more information, refer to the [blog on implementing CDC-based upserts](https://aws.amazon.com/blogs/big-data/implement-a-cdc-based-upsert-in-a-data-lake-using-apache-icebe

For a real-world use case, we can choose sample e-commerce order data to set up a Security Analytics detector to protect against ransomware attacks. E-commerce platforms are frequent targets due to the valuable financial data they hold.

Use Case: Protecting E-commerce Order Data from Ransomware

Scenario:

We want to set up a Security Analytics detector in Amazon OpenSearch Service to monitor for ransomware activities like data exfiltration and system state backup deletion, commonly seen in ransomware attacks like BlackCat and LockBit.
