Tricks using Cloud #3: Deploying a Serverless Telegram Bot with AWS

Tricks using Cloud #3: Deploying a Serverless Telegram Bot with AWS

Comments 0 Comment

In this episode, we’ll learn how I combined AWS services to build a lightweight monitoring service that interacts directly with a Telegram bot without deploying any server o container. When people first hear about serverless computing, they often imagine something abstract or overly complex. In reality, services like AWS Lambda and API Gateway make it possible to build real-world, production-ready applications without provisioning or maintaining any servers. Why Serverless? Serverless is not about “no servers.” It’s about abstracting infrastructure management….

How the $300B OpenAI deal redefines the race for AI infrastructure OpenAI has just signed a $300 billion deal with Oracle Cloud. This is not a standard cloud services contract — it is one of the largest tech investments in history, and it says a lot about where IT infrastructure is heading. One of the striking aspects of this deal is its energy demand: Oracle disclosed the need for about 4.5 gigawatts of electric power capacity to support the infrastructure….

AI-Optimized Infrastructure Is the New Baseline

AI-Optimized Infrastructure Is the New Baseline

Comments 0 Comment

Today, AI-optimized infrastructure is becoming the default expectation in both cloud and on-prem environments. Whether you’re building for analytics, DevOps pipelines, or customer-facing apps, AI is part of the picture and your architecture needs to be ready for it. From General Purpose to AI-First For years, cloud design was about scaling general-purpose workloads: web apps, databases, storage, batch processing. Now the journey is clear: The result? Infrastructure that’s not AI-ready is already behind. Key Infrastructure Changes 1. GPUs and AcceleratorsAI…

When talking about cloud strategy with Customers, or doing assessments, I often get this question: “Should we go public, private, or hybrid?” As a Cloud Architect, I could give a technical breakdown. But over time, I’ve learned the real answer depends on the business context. And usually we will explore all the possibilities. Public Cloud: When Agility Wins Public cloud platforms like AWS, Azure, and GCP are the go-to choice for organizations prioritizing speed, scalability, and innovation. Common Use Cases…

From Traditional VPNs to Cloud-Native Networking: What I Learned from CloudConnexa

From Traditional VPNs to Cloud-Native Networking: What I Learned from CloudConnexa

Comments 0 Comment

Over the past few years, the cloud transformation has gone far beyond computing and storage. Even the network layer — traditionally tied to on-premise infrastructure — is evolving rapidly. For many, VPN still means hardware appliances, IPSec tunnels, and a growing mess of firewall rules. But after working with CloudConnexa by OpenVPN, I started seeing secure remote access from a new angle — one aligned with modern Zero Trust principles. Traditional VPNs: What’s Not Working Anymore In client environments, I’ve…

How I Passed the AWS Security Specialty Exam – Lessons from the Journey

How I Passed the AWS Security Specialty Exam – Lessons from the Journey

Comments 0 Comment

Earlier this year, I set a personal goal: to earn the AWS Certified Security – Specialty certification. Not just for the badge, but to push myself into mastering the strategic and technical aspects of cloud-native security on AWS—something I found increasingly relevant in my day-to-day work. This wasn’t a simple study path. It became a structured, layered project of learning, revisiting concepts, and challenging assumptions I didn’t even know I had. Why I Took the Exam I already had solid hands-on experience…

Understanding DNS with an overview of AWS Route 53

Understanding DNS with an overview of AWS Route 53

Comments 0 Comment

The Domain Name System (DNS) functions like a phone directory. Instead of looking up a person’s name to find their phone number, your computer looks up a domain name to find the corresponding IP address. This process involves several types of DNS servers, including recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers like Google 8.8.8.8 or Cloudflare 1.1.1.1 or your home router that forwards DNS query to your Internet Provider’s DNS Server. For example, if we run nslookup command…

Nowadays, cloud computing has become an integral part of business operations, but with these benefits, comes the critical need for robust security measures. By ignoring them, have impact also in our private life. Most of us have own vacations photos or any other photos as backup in the cloud, and thinking that these could be hacked, it drives us crazy. Fortunately, the shared responsibility model ensures that both cloud service providers (CSPs) and customers work together to maintain a secure…

Comparing and understaning Cloud Computing Service Models with a traditional environment can be helpful in cloud journey decision. But which model can you embrace…and why ? IaaS, PaaS, SaaS are three models allow you to manage some parts of your infrastructure, or nothing at all. Let’s doing an analogy with Pizza. In a traditional infrastructure, following pizza recipe of course, we need to buy whatever we need to make an home pizza-making (cheese, tomato, dough) and we need to consume…
