Amazon Macie: A Comprehensive Solution for Data Security and Privacy

Wed, 10 Sep 2025 08:00:00 +0200

I. Introduction to Amazon Macie

Amazon Macie is a fully managed data security service provided by AWS. It uses machine learning and pattern matching to automatically discover, classify, and protect sensitive data stored in Amazon S3. It provides risk visibility, generates findings when security or privacy issues are detected, and automates protective actions. A 30-day free trial is included for automated S3 bucket evaluation and data scanning.

I. Overview of Amazon Inspector

Amazon Inspector is an automated vulnerability management service on AWS that automatically discovers workloads such as EC2 instances, container images in ECR, and Lambda functions, and continuously scans them for software vulnerabilities and unexpected network exposures.
It generates findings used to prioritize patches based on a contextualized risk score, which adapts the CVSS score according to the environment (e.g., absence of open ports).

AWS Containers

I. Introduction

Containers encapsulate an application and all its dependencies in an isolated and reproducible environment. Unlike virtual machines, containers share the host system’s kernel, making them lighter, faster to start, and easier to deploy.

This approach has revolutionized the software lifecycle by improving the portability of applications between environments (development, testing, production).

AWS offers several services to build, manage, orchestrate, and run containers. Each service fits a specific level of control, user expertise, or application type.

Global Availability of EC2 Instance Types

Wed, 13 Aug 2025 07:57:39 +0200

I. Introduction

When designing infrastructure on AWS, one of the first technical decisions involves the EC2 instance types used. However, this decision cannot be made in isolation: the regional availability of instance types varies by geographic location, impacting your architecture’s resilience, scalability, and cost.

This article explains in detail how to understand and anticipate this global availability, with a clear approach directly applicable by developers, DevOps engineers, and data scientists.

I. What is Amazon EC2 and what is it used for?

AWS Expert: Amazon EC2 (Elastic Compute Cloud) is an on-demand infrastructure service that allows you to launch virtual servers — called instances — in the cloud. It is used to host web applications, run data processing, serve as development environments, or simulate production loads.

What makes EC2 powerful is its scalability and flexibility. You can start with a small instance for testing, then scale up to high-capacity clusters without switching platforms. Developers also love the full control they get over configuration, open ports, attached disks, and more.

3 Simple Ways to Save Up to 90% on EC2 Costs: Spot Instances

Fri, 02 May 2025 17:08:49 +0200

I. Introduction to Spot Instances

Amazon EC2 Spot Instances offer a powerful way to drastically reduce cloud computing costs. Designed to utilize unused Amazon EC2 capacity, these instances are available at a price up to 90% lower than On-Demand instances.

While these savings are appealing, Spot Instances are not suitable for all workloads. They are ideal for flexible, interruption-tolerant, or distributed jobs such as data processing, machine learning training, or performance testing.

Real-Time, Real-Easy: Deploying WebSockets

Mon, 21 Apr 2025 16:06:29 +0200

I. WebSocket Protocol Architecture and Workflow

Establishing a WebSocket involves an initial HTTP(S) handshake, followed by a protocol upgrade to WebSocket.

Main Steps:

Step	Description
1. HTTP Upgrade	The client sends an HTTP request with the `Upgrade: websocket` header.
2. Acceptance	The server validates the upgrade and switches to WebSocket mode.
3. Communication	Data is exchanged in frames, asynchronously and bidirectionally.

Example upgrade request:
