Hi all! Welcome to my next blog. Today I am going to share about a tech meetup which was I attend recently. The meetup was organized by Code On JVM at Contentstack.
That was a great experience for me. The environment(Contentstack) was truly inspiring, such a great place to work and learn. We had three insightful presentations that deepened my understanding of Java and its ecosystem.
One of the highlights for me was getting introduced to the CMS world, especially the concept of Headless CMS, which was completely new to me.
Let's see about Headless CMS.

Why it's called “Headless”?

• The “head” is the front-end (like a website or app).
• “Headless” means the CMS doesn’t have a built-in front-end. It just provides content via APIs (usually REST or #GraphQL), and developers build the front-end separately.

Example:

This example will give you a clear understanding. It’s Like a Box of Content.

• You fill the box (headless CMS) with your articles, images, etc.
• Then your developer takes the content out and shows it however they want.

Usage difference between Traditional CMS and Headless CMS:

Use Traditional CMS when:

• You only need a website
• You want less coding
• You want to get started quickly

Use Headless CMS when:

• You want to build multiple platforms (app, website, etc.)
• You want more flexibility in design and code
• You have developers to build the front-end

How it Works:

• Content creators write/manage content in the CMS (text, images, etc.).
• The CMS exposes this content via an API.
• Front-end developers fetch the content and display it using any framework (React, Vue, Angular, mobile app, etc.).

Examples of Headless CMS:

• Contentful
• Strapi
• Sanity
• DatoCMS
• Prismic
• Hygraph (formerly GraphCMS)

That's it, guys. I hope I gave a basic clear explanation about Headless CMS. Thank you for reading my blog. Will see you in my next Blog.

Attended the Grafana & Friends Meetup Yesterday!

I usually have a question. As a developer, i have logs, isn’t that enough. With curious mind, i attended Grafana & Friends Chennai meetup (Jan 25th 2025)

Had an awesome time meeting fellow tech enthusiasts (devops engineers) and learning about cool ways to monitor and understand data better.
Big shoutout to the Grafana Labs community and Presidio for hosting such a great event!

Sandwich and Juice was nice

Talk Summary,

1⃣ Making Data Collection Easier with Grafana Alloy
Dinesh J. and Krithika R shared how Grafana Alloy, combined with Open Telemetry, makes it super simple to collect and manage data for better monitoring.

2⃣ Running Grafana in Kubernetes
Lakshmi Narasimhan Parthasarathy (https://lnkd.in/gShxtucZ) showed how to set up Grafana in Kubernetes in 4 different ways (vanilla, helm chart, grafana operator, kube-prom-stack). He is building a SaaS product https://lnkd.in/gSS9XS5m (Heroku on your own servers).

3⃣ Observability for Frontend Apps with Grafana Faro
Selvaraj Kuppusamy show how Grafana Faro can help frontend developers monitor what’s happening on websites and apps in real time. This makes it easier to spot and fix issues quickly. Were able to see core web vitals, and traces too. I was surprised about this.

Techies i had interaction with,

Prasanth Baskar, who is an open source contributor at Cloud Native Computing Foundation (CNCF) on project https://lnkd.in/gmHjt9Bs. I was also happy to know that he knows **parottasalna** (that’s me) and read some blogs. Happy To Hear that.

Selvaraj Kuppusamy, Devops Engineer, he is also conducting Grafana and Friends chapter in Coimbatore on Feb 1. I will attend that aswell.

Saranraj Chandrasekaran who is also a devops engineer, Had a chat with him on devops and related stuffs.

To all of them, i shared about KanchiLUG (https://lnkd.in/gasCnxXv) and Parottasalna (https://parottasalna.com/) and My Channel on Tech https://lnkd.in/gKcyE-b5.

Thanks Achanandhi M for organising this wonderful meetup. You did well. I came to Achanandhi M from medium. He regularly writes blog on cloud related stuffs. https://lnkd.in/ghUS-GTc Checkout his blog.

Also, He shared some tasks for us,

1. Create your First Grafana Dashboard.
Objective: Create a basic Grafana Dashboard to visualize data in various formats such as tables, charts and graphs. Aslo, try to connect to multiple data sources to get diverse data for your dashboard.

2. Monitor your linux system’s health with prometheus, Node Exporter and Grafana.
Objective: Use prometheus, Node Exporter adn Grafana to monitor your linux machines health system by tracking key metrics like CPU, memory and disk usage.


3. Using Grafana Faro to track User Actions (Like Button Clicks) and Identify the Most Used Features.

Give a try on these.
