Welcome to the Journey of Cloud Engineering

In traditional IT environments, security was built around the network perimeter. Firewalls! VPNs! Internal networks!!! If you were inside the network, you were trusted; but, cloud changed everything. Today, users access systems from: Homes Airports Mobile devices Multiple countries SaaS platforms Hybrid environments The perimeter is no longer the network. The perimeter is identity!!! Why Identity Is the Core of Modern Cloud Architecture Every cloud system depends on answering one fundamental question: Who are you; and what are you allowed to do? Whether you are: Logging into a CRM Accessing SharePoint Deploying infrastructure Querying a data warehouse Using a SaaS platform Identity is verified before anything happens. This is why Identity & Access Management (IAM) is not just an IT function; it is a core architectural component . What Enterprise Identity Actually Includes Modern cloud identity platforms typically handle: 1. A...

So far in this journey, we’ve discussed cloud databases and how they power applications. But here’s a critical shift: Databases run transactions. Data warehouses drive decisions!!! This distinction becomes more important as organizations grow. Let me ask you: Is your production database optimized for: Handling user logins? Processing transactions? Updating records in milliseconds? Or is it optimized for: Aggregating millions of records? Running complex analytical queries? Powering executive dashboards? Trying to do both on the same system often leads to performance bottlenecks. OLTP vs OLAP – The Core Difference At the heart of this discussion are two different system designs. OLTP (Online Transaction Processing) Used by live applications. Fast inserts and updates Highly normalized data Consistency-focused Short queries Examples: E-commerce checkout CRM updates ERP transactions OLAP (Online Analytical Processing) Used f...

Every application, no matter how small or large, revolves around one thing: data . User accounts, transactions, messages, configurations, logs, analytics - all of it lives in a database. Without a database, most applications simply cannot function. But the way databases are managed has changed dramatically with the cloud. Let me start with a simple question: Would you rather spend your time building features - or patching database servers at 2 AM? This is exactly the problem that Database as a Service (DBaaS) was designed to solve. The Traditional Way: Self-Managed Databases Before cloud platforms matured, organizations managed their own databases. This involved: Provisioning servers Installing database software Configuring storage Setting up backups Monitoring performance Applying security patches Planning capacity Every part of the database lifecycle was the responsibility of the IT team. This approach offered full control , but it also came with: ...

Once you understand cloud fundamentals and basic web architecture, the next big question appears: Which cloud provider should I choose for hosting my web application? The three major players ( Microsoft Azure , Amazon Web Services , and Google Cloud Platform) ,  all offer powerful hosting solutions; however, they don’t approach the problem in exactly the same way. Choosing the “best” cloud is not about popularity. It’s about matching your workload, team skills, and business goals . Let’s break this down from a cloud engineering perspective. What Matters When Hosting a Web App? Before comparing providers, ask these questions: Do I need full server control or managed platforms? How much traffic will the app handle? How important is global reach? Do I need enterprise integrations? What is my team already familiar with? Your answers shape the decision far more than feature lists. Azure: Enterprise Friendly and Microsoft - Centric Azure is often the natural c...
