KubeCon + CloudNativeCon India 2025: My experience

1 Reply

From scaling Kubernetes, observability, powering huge AI projects to real stories from PepsiCo, Flipkart, and Intuit, KubeCon + CloudNativeCon India 2025 in Hyderabad was a deep dive into where cloud-native ecosystem is headed. Here’s my personal experience about the event.

I had the chance to attend KubeCon + CloudNativeCon India this year. Its a two-day technical conference packed with thoughtfully curated keynotes, tech talks, and lightning sessions from the people shaping the Kubernetes ecosystem and the cloud-native world. The event also featured ~30 product/solutions booths showcasing solutions to help organizations with Kubernetes workloads, security, scaling, observability, platform engineering and their AI journey. Before we get into more details, take a look at these key numbers and details:

Held at Hyderabad International Convention Centre (HICC).
Happened on 6-7 August 2025.
Sessions
- 12 Keynote sessions
- 10 lightning talks
- 56 Tech sessions on K8s, Observability, Scaling, Security, AI + ML, Platform engineering, etc.
Approx ~4000 registrations

The 2026 KubeCon India is announced to be held in Mumbai!
Watch this event’s session recordings, available on the CNCF YouTube Channel.
Review session slides from speakers who provided them via the event schedule.

With so much on the agenda, it’s very difficult for one person to attend everything. That’s why pre-planning is essential for events of this scale. It was worth creating a schedule focused on the sessions and booths that match your interests. The Sched app made this much easier, helping me build my personal agenda so I wouldn’t miss anything important.

My experience

I traveled with my team to attend the event, and ignoring the travel fatigue, we made it to HICC by 8 AM for the check-in formalities. We were ready after security checks done and we received our event badges. The venue welcomed us with tea, coffee, and cookies – a much-needed warm-up before a day packed with technical deep dives.

By 9:30, as per the agenda, the keynote sessions started. The crowd was so massive that the main hall quickly filled up, but crew arranged adjacent halls with big screens for live streaming. We settled into one of those adjacent halls, but due to some technical glitches with the screen and audio, we decided to head back to the main hall and stand along the sides just to catch the keynotes live. After an hour of inspiring talks (and sore legs :D), we stepped out for a break and then dove into exploring the product and solution booths.

The booths were sparkling with energy! Attendees deep in conversations with booth teams, exploring new features and solutions – it was a energetic sight! It was great to see fresh graduates in the mix, already well-versed in cloud technologies. The enthusiasm was contagious, and of course, no developer conference is complete without a shower of freebies and laptop stickers. We do collected a healthy stash!

The iconic “Kubestronauts” blue jackets were turning heads throughout the venue. It’s a title one can earn by completing five Kubernetes and cloud-native certifications, a badge of honor that carries serious weight in the Kubernetes world today. Seeing a few Kubestronauts proudly sporting those jackets was truly inspiring!

We split up to cover more ground, each visiting different booths. My own highlights are the insightful discussions I had at the AWS and Nudgebee booths. Both offered interesting perspectives and solutions worth exploring further.

The organizers smartly arranged lunch across multiple dining designated areas, which helped spread out the crowd and made it possible for attendees to enjoy a peaceful, crowd-free meal.

We contiunued the second day with similar agenda of attending sessions and booths gathering every possible bit of the information that could help us keeping tab of the Cloud Native and Kubernetes world and industry progress in those domains. ArgoCD scaling, Platform Engineering, EKS Auto mode, EKS dashboards, Observability, AI integration for troubelshooting and Ops to name a few.

I also ran into a former colleague and reconnected with some contacts from AWS I had worked with in the past during the event. Also, got to see some open source community leaders, some well known personalities from Kubernetes/Cloud world in person. These technical conferences are they best way to network and socialize!

Reflections on AWS Summit Mumbai 2025

I had the opportunity to attend the AWS Summit Mumbai 2025 on June 19th. In this post, I’ll be sharing my insights and reflections from the event.

AWS Summit,Mumbai!

AWS Summit is not a AWS re:Invent!

The AWS Summit is a regional tech conference held multiple times a year, designed to showcase majorly customer stories, real-world use cases, product applications, and technical journeys powered by AWS. It’s focused on knowledge sharing and community engagement rather than major product announcements.

In contrast, AWS re:Invent is AWS’s global, annual flagship event. It’s where the company unveils new services, features, and products, alongside deep-dive technical sessions, training, and certification opportunities.

So, if you’re attending an AWS Summit, don’t expect groundbreaking announcements. Instead, think of it as a community event focused on learning, networking, and exchanging experiences with the local digital and tech ecosystem.

AWS Summit Mumbai 2025

AWS Summit Mumbai 2025 was focused on sharing the stories and products that harnesses the power of Cloud Computing and AI for accelerating digital transforming journey of India. Yes, a lot of AI was in the air!

It kicked off with the Keybote from AWS leaders: Sandeep Dutta – President – AWS India and South Asia and Ganapathy Krishnamoorthy VP – Databases – AWS. The keynote also included the the talks from Industry leaders: Dr. Tapan Sahoo (Head of Digital Enterprise and Information & Cyber Security, Maruti Suzuki India) and Rajesh Chandiramani (CEO, Comviva).

Keynote was followed by nearly 40+ breakout sessions in various technologies like databases, AI, observability, FinTech, etc. that showcased how industry in India is leveraging the power of AWS and AI to shape their future.These sessions were categorized into 6 tracks :

Building for Scale
Generative AI on AWS
Migration and modernization
AWS for Data
Security, compliance & resilience
Innovate with AWS Partners

The experiences at the venue included builders zone (offering hands-on to latest AWS services), Industry hub (business tailored, cloud native solution products), Business innovation hubs (convergence point for organizations), AWS Game Day (2-hours hackethon mainely focused on usage of AWS AI services) and AI Hub (Hands-on to AWS AI services).

My experience at AWS Summit Mumbai 2025

The event was really well organized and took place at the impressive Jio World Convention Centre in Mumbai. The venue itself was top-notch, and the food—breakfast, lunch, and high tea—was genuinely delicious.

Even though the space is huge, the number of attendees made it feel a bit crowded at times. There were some cool photo spots set up that captured the spirit of Mumbai, which added a nice local vibe to the event.

The breakout sessions were intense—over 40 sessions packed into just three hours (1:30 PM to 4:30 PM)! Even with a plan in place, it was tough to jump from one session to another, especially with sessions happening in different halls. You’d almost always miss the first few minutes of the next session. A 5-minute buffer between sessions would’ve made a big difference.

There wasn’t much time left for networking or checking out the booths unless you sacrificed a bit of your lunch or break time. That said, the overall vibe was electric—full of tech buzz, especially around AI. I also ran into a few former colleagues, which was a really nice, nostalgic surprise!

Understand and learn about data center tier. The article explains the data center standardization matrix: tier 1 to tier 4 along with its eligibility criteria.

Data center tiers

Most of our readers are system administrators and surely come across term call data center tiers in their sysadmin life. This article will walk you through what is data center tiers? Different types of data center tiers, what is tier 1, tier 2, tier 3, and tier 4 data center? Which tier data center have maximum availability? etc.

All these might be interview questions for system architects at the beginner level. As a sysadmin its always good to know data center tiers so that you are well verse with your company infrastructure and can decide if that can really deliver on SLAs defined in your environment.

Without further delay, lets start with our topic.

What is data center tier?

Datacenter tier is the standardization matrix that defines overall performance, availability, fault tolerance capability, operating environment of a data center. It defines how the data center is fault-tolerant, how it can sustain to failures of various components, power, connectivity links, etc. It defines availability being offered for hosted servers.

Basically data center tier helps customers to determine which tier is best suitable for their application depending on the SLA requirement and data critical index they have. Mission-critical services should be hosted under a higher tier data center whereas less critical data should be hosted in lower-tier data centers. Obviously cost is another factor here too. As you go on high with tier, cost increases for hosting.

Different data center tiers

There are 4 data center tier standards defined by Uptime Institute. They are as below :

Tier 1: Non-redundant capacity and single power, connectivity distribution
Tier 2: Tier 1 feature + redundant capacity
Tier 3: Tier 2 features + Multiple independent power, connectivity distribution + onsite energy production system
Tier 4: Tier 3 features + All components are fault-tolerant, continuous cooling equipment.

A detailed list of requirements to be fulfilled by the data center to be eligible for specific tier is available here.

Data center tier deciding factors :

Datacenter to be eligible for certain tier it should complete certain criteria (as we saw above). There are many factors that affect/help in achieving those criteria. These factors are as below –

Datacenter design, location
Mechanical infrastructure design
Technology infrastructure design
Electric power distribution
Cables distribution
Network and internet connectivity distribution
Fire protection
Security in terms of soft security and physical security controls like biometric etc
Energy production, use, efficiency
Waste management
Environmental control and effects
Cooling management
Capacity management

Accepted downtime and availability tier wise

Tier 1: 99.671% uptime, 28.8 hours downtime per year
Tier 2: 99.749% uptime, 22 hours downtime per year
Tier 3: 99.982% uptime, 1.6 hours downtime per year
Tier 4: 99.995% uptime, 26.3 minutes downtime per year

That’s all I have to share with you about data center tier standards. Feel free to point out mistakes, suggestions, feedback in the comments section below.

Happy Sysadmin Day 2017!!

First of all,

Happy Sysadmin Day to all our readers

Yes, its 28 July 2017! System Administrator Appreciation Day 2017!

Sysadmin day is normally last Friday of July month. This year its 18th annual Sysadmin day.

Sysadmin! He/she is the one who keeps your digital world running from behind the scenes. Anything digital you use right from your computer to your ATM card machines, sysadmin is behind them to keep them running healthy. Sysadmin never gets any appreciation he deserves. He works 365 days of year-round the clock even in graveyard shifts. His clock always ticks to make services available all the time. When systems are down everyone else is at ease, the only sysadmin is the one who gets all the heat and overworked to get systems back up. You can not imagine the digital world without sysadmin!

What is sysadmin day

It is a day dedicated to the appreciating system administrator. They are the real hero keeping your digital world running! So why not dedicate one day to appreciate the work they do for you! Appreciate their hard work, their holiday sacrifices, their tolerance when they take heat during downtime, their extra workloads keeping your digital infra up to date. Let’s appreciate at least one sysadmin today by greeting them, gifting them, exchanging little talk with them & expressing thankfulness!!

There are few ways you can appreciate your sysadmin listed here on sysadminday.com. Those are really worth considering.

Cheers!!

Thank you readers (mostly all of you are sysadmins!) for stopping by! Enjoy your day! And yes, for my Linux buddies – Have a happy shell!

Blog enhancements for better SEO

KernelTalks implemented few blog enhancements for better SEO and reader engagement. Addition of SSL, AMP & browser push notifications to blog

SSL, AMP and notification! Blog enhancements.

A few months ago we did blog enhancement for better speed and cleaner look by adding premium theme built on Genesis framework and CDN support for lightning-fast page loads. This month we are adding a few more enhancements and features to blog which helps us build better SEO and people engagement.

SSL support

We have added SSL support to our blog. Now kerneltalks.com loads over https protocol (more secured). Information sends to us will be secured over the internet. Since many of you already know, SSL is one more factor to rank pages in search by Google. This implementation will help us building good ranks in Google search results and building more organic traffic.

Blog is now AMP ready

Google in recent times declared AMP (Accelerated mobile pages) as one of the ranking factors. AMp ensures loading pages on mobile devices almost in no time. This is done via removing all scripts, styling, and very limited special HTML tagging of page. KernelTalks now AMP ready! Now our posts are listed in google results with AMP lightning icon!

AMP pages

You can even view the amp version of kerneltalks by appending /amp to any of our URLs in the browser. We are more closer to the audience with lower bandwidth and loading our pages lightning fast even on mobile devices. If you want to customize and stylish your AMP pages try plugin named AMP for WP. It has all customization you need along with the option to configure AdSense ads.

Browser push notifications

One more reader engagement option enabled for kerneltalks. We have started browser push notifications (supports Chrome, Firefox, Safari) which will notify you about our new articles whenever you open up your browser. You can opt into these notifications by clicking allow in a popup window when you now visit kerneltalks.com. We are using Onesignal push utility for this. This is the best free service allowing unlimited subscribers so you can go for it if you are looking for one for your blog.

That’s all for now! Keep blogging! Let us know your feedback about our blog in the comments.

8 Wannacry ransomware memes take over the Internet

Gallery of wannacry ransomware memes that take over Internet after major cyber attack broke over the weekend.

Wannacry ransomware memes

As everyone is aware the Internet world has been hit by ransomware called WannaCry last weekend. It was a nightmare for Wintel admins as their whole weekend was burned into patching windows servers in their environments. Obviously Linux world was pretty quiet since WannaCry targeted Windows operating systems only.

No wonder, the Internet got filled with lots of memes about this cyber attack. I collected a few of them here:

Read & share !

Note: Image credits are links from where I collected that image. The origin/creator of the image might be different.

If you have any meme about wannacry let us know in comments!

Its a century! Celebrating 100 posts!

Here we are on the 100th block! Kerneltalks journey of 4 months reaching a milestone of 100 posts! Crawling web of Linux, Unix & scripts for the goodness of sysadmin!

And here we are!!!! on 100th post!!!!

kerneltalks.com was registered in Oct 2016, to take a journey of kerneltalks.blogspot.com further into wider space. In 3-4 months of the span, KT has grown to 100 posts database of Linux, Unix, and Script related stuff. We have observed 40K pageviews in this period and a continuously growing organic search number!

There were a couple of technology enhancements done to run KT smoothly and give an awesome reading experience to all its readers.

KT started getting feedback, questions from its readers over email. Social branding is one of the aspects KT just started and advancing at a low pace day by day. As of today, KT having 377 fans on its Facebook page, 5 Google+ followers, 15 Twitter followers, 19 Feed readers, and 28 email subscribers. Totaling 444 social followers. Although these numbers look pretty small they are growing and yes they are not paid ones!

KT also gained a leap in Alexa ranking. Currently its ranked 4,00,728th popular website in the world and 33,529th in India. If you are into blogging and know what is Alexa, you definitely love these numbers!

I hope the same continuity in the future and would like to see these numbers greatly raised when KT reaches 200 posts milestone! Till then, have a good time! Happy surfing!!
