Monitoring sucks.

Or at least when everything goes well.

But when a site crashes or slows down in performance, that's when you see team members pulling graphs and logs to get a clue.

Don’t wait for chaos; set up your metrics from day one.

My first experience with Prometheus has been positive. Here's what I found:

- Easy to install.
- Separate processes for each purpose: Prometheus, Alertmanager, Blackbox Exporter, etc.
- Uses YAML files! I love this because, with my DevOps background, it makes the configuration easy to understand.

I opened a website from Google, saw an error, and left for the next option. That site lost a potential customer.

This highlights the importance of monitoring systems so owners can act fast.

Boost your web apps with 6 AWS services.

My small website cost just $0.56 in December, a savings of 88.8% from the $5 on a Lightsail instance without CDN.

For my low usage, Amplify is perfect for quickly building and testing apps.

AWS offers cheaper options with growth but needs infrastructure management. Amplify simplifies setup.

Happy new year community!

Key strategies for zero-downtime network moves:

• Blue-Green: Alternate between active and idle setups.
• Canary: Test on a subset before wider release.
• A/B Testing: Compare versions via feedback.
• Phased Rollouts: Gradual feature introduction.
• Load Balancing: Evenly distribute traffic.

IPv4 vs IPv6.

It's essential to get familiar with the basic differences. IPv4 addresses have already run out. The only way to obtain them is through private resellers, which can be expensive.

In the upcoming years, we will start seeing more and more IPv6 for sure.

Merry Christmas to everyone who celebrates it! 🎅

Managing IPs and subnets is tough. Use Jinja2 and Python to save time.

Jinja2 creates dynamic content with logic.

Workflow:
1. User inputs data via CLI.
2. Python processes it with Jinja2.
3. Outputs updated config file.

Examples show Jinja2 updating `cidr_block` in Terraform resources.

Perfect scores on all Google website performance! - 100/100/100/100 😲

My little website playground with Astro and AWS Amplify has an outstanding performance.

It's a simple website, but wow, it's my first time seeing 100 score for all tests.

I began my tech career over 15 years ago, aiming to be a senior network engineer. Initially, I couldn't secure that role and worked in IT support instead, gaining indirect network experience. After 2 years, I became a network engineer.

There are many paths to your goals—stay flexible.

Astro website deployed with AWS Amplify using GitHub repo.

Now, every time I do a git push, the code gets automatically deployed.

Amplify is an interesting serverless solution to deploy React applications on the cloud. The best part is that it offers an integrated CDN globally.

Struggling to create Bash shell scripts.

Even when using ChatGPT, sometimes they might not work as expected.

I know that’s really frustrating.

I came across this cool website that checks the syntax.

Goodbye, Sydney!

After nearly 7 years in this lovely city, it's time to move back to Europe.

I'm not only moving continents; for the first time in my career of 17 years, I have decided to leave my job at AWS and build my own future as an entrepreneur.

Exciting times ahead.
