October 2025 is still tough in cloud computing, as Amazon Web Services and Microsoft Azure two major cloud providers experience a massive outage, affecting a multimillion userbase, and who knows how many systems worldwide. Not only do these massive outages expose the fickle and brittle nature of the increasingly well-connected global cloud infrastructures, they also reiterate the cloud’s complexity and demand for solid development and infrastructure oversight. In this article, we break down both outage incidents including the timing, the technical cause of the incidents, overview of the service impact, and much-needed lessons for cloud architects and DevOps dots.

Logs to Alerts with CloudWatch Filters
Why Alarms Matter in Cloud Infrastructure
Proactive monitoring for reliable cloud systems
The Critical Role of Monitoring
In any modern cloud-based architecture, monitoring and alerting play a critical role in maintaining reliability, performance, and security.
Beyond Just Logs
It’s not enough to just have logs-you need a way to act on those logs when something goes wrong. That’s where CloudWatch alarms come.
The Cost of Being Reactive
Imagine a situation where your application starts throwing 5xx errors, and you don’t know until a customer reports it. By the time you act, you’ve already lost trust.
Alarms prevent this reactive chaos by enabling proactive monitoring—you get notified the moment an issue surfaces, allowing you to respond before users even notice.
The Risks of Operating Without Alarms
!
Missed Error Spikes
You might miss spikes in 4xx/5xx errors that indicate growing problems.
⌛
Reactive Mode
You’re always proactive instead of reactive.
👁️
Lack of Visibility
Your team lacks visibility into critical system behavior.
🔍
Diagnosis Challenges
Diagnosing issues becomes more difficult without early signals.
The CloudWatch Alarm Solution
Due to all the reasons above, that’s why I decided to implement AWS CloudWatch Alarms using Metric Filters—a cost-effective, powerful way to monitor logs and trigger alerts based on specific patterns.

Technical Case Study: Amazon Redshift and Athena as Data Warehousing Solutions
Introduction
Modern data architectures demand flexible, scalable, and cost-effective solutions that can handle diverse analytical workloads. Amazon Web Services offers multiple data warehousing approaches that serve different needs:
- Amazon Redshift: A petabyte-scale, fully managed data warehouse designed for complex analytical queries
- Amazon Athena: A serverless query service that allows direct querying of data in S3.

Cloud Red Teaming – Simulating Attacks with Open-Source Tools
What if your cloud environment isn’t as secure as you think? As businesses rush to the cloud, attackers follow exploiting misconfigurations, weak access controls, and hidden vulnerabilities. Cloud red teaming flips the script, letting you simulate real-world attacks before hackers do. But how? With open-source tools, you can safely test defenses, uncover gaps, and stay ahead.
Ready to see if your cloud can withstand the storm? Let’s dive in.
