Understanding Amazon Route 53 Routing Policies: A Comprehensive Guide

Amazon Route 53 is a highly scalable and reliable Domain Name System (DNS) web service introduced to route end users to Internet applications. One of the key features of Route 53 is its ability to route traffic using different routing policies, depending on your needs. Each policy helps you optimize traffic management, improve availability, and create a more resilient application infrastructure. In this post, we’ll take a deep dive into the seven main routing policies available in Route 53.

1. Simple Routing Policy

How to Optimize Amazon Redshift for Faster and Seamless Data Migration

When it comes to handling massive datasets, choosing the right approach can make or break your system’s performance. In this blog, I’ll take you through the first half of my Proof of Concept (PoC) journey—preparing data in Amazon Redshift for migration to Google BigQuery. From setting up Redshift to crafting an efficient data ingestion pipeline, this was a hands-on experience that taught me a lot about Redshift’s power (and quirks). Let’s dive into the details, and I promise it won’t be boring!

Stream and Analyze PostgreSQL Data from S3 Using Kafka and ksqlDB: Part 2

Introduction

In Part 1, we set up a real-time data pipeline that streams PostgreSQL changes to Amazon S3 using Kafka Connect. Here’s what we accomplished:

  • Configured PostgreSQL for CDC (using logical decoding/WAL)
  • Deployed Kafka Connect with JDBC Source Connector (to capture PostgreSQL changes)
  • Set up an S3 Sink Connector (to persist data in S3 in Avro/Parquet format)

In Part 2 of our journey, we dive deeper into the process of streaming data from PostgreSQL to S3 via Kafka. This time, we explore how to set up connectors, create a sample PostgreSQL table with large datasets, and leverage ksqlDB for real-time data analysis. Additionally, we’ll cover the steps to configure AWS IAM policies for secure S3 access. Whether you’re building a data pipeline or experimenting with Kafka integrations, this guide will help you navigate the essentials with ease.

Can Cloud Data Be Hacked? Common Threats and How to Secure Your Cloud Environment

Cloud computing has become integral to our daily lives, often in ways we don’t even notice. The cloud has transformed how we manage and access data, from backing up photos on smartphones to sharing files and collaborating on documents. However, the cloud isn’t immune to security risks like any online platform. Cyberattacks targeting cloud data are a real concern and deserve careful attention. 

In this blog, we’ll explore the potential vulnerabilities of cloud storage and share actionable steps to protect your data effectively.

Top 10 Lessons Learned from Failed Cloud Migrations: What Went Wrong?

What separates successful cloud migrations from disastrous ones?

Cloud migration is often hailed as the ultimate solution for scalability and cost-efficiency, yet many companies find themselves stuck in rising costs, security vulnerabilities, or operational chaos. Why do these failures happen?

Is it poor planning, unrealistic expectations, or simply the wrong approach? In this blog, we’ll uncover the stories behind failed cloud migrations, the lessons they teach, and how businesses can turn potential disaster into long-term success.

10 Lessons From Past Cloud Migration Failures

Cloud migration has transformed how businesses operate, but not all journeys to the cloud have been smooth. Many migrations fail due to common pitfalls that, if identified early, can be avoided. Here are 10 crucial lessons derived from past cloud migration failures:
