“Top 10 AWS Services You Must Know for CLF-C02 & SAA-C03 Exams”

 ⚡ Top 10 AWS Services You Must Know for CLF-C02 & SAA-C03 Exams ⚡


If you're preparing for the AWS Cloud Practitioner (CLF-C02) or AWS Solutions Architect Associate (SAA-C03), you *must* understand the core AWS services that power the cloud.  

These 10 services form the foundation of most AWS questions — and mastering them will boost your exam score and real-world confidence. 🚀


☁️ 1. Amazon EC2 (Elastic Compute Cloud)


EC2 lets you launch virtual servers in the cloud.  

You choose the instance type, operating system, and storage, then pay only for what you use.  

➡️ Think of it as renting a virtual computer from AWS.


💾 2. Amazon S3 (Simple Storage Service)


S3 is used to store any kind of data — files, backups, logs, or media.  

It’s highly durable (99.999999999% durability!) and scalable.  

You only pay for the storage you actually use.

🗂️ 3. Amazon RDS (Relational Database Service)


RDS makes it easy to set up, operate, and scale relational databases in the cloud.  

It supports MySQL, PostgreSQL, Oracle, SQL Server, and Amazon Aurora.


🧱 4. AWS Lambda


Lambda lets you run code *without provisioning servers*.  

Just upload your function, and AWS runs it automatically when triggered.  

Perfect for automation, APIs, and event-driven apps.


🌍 5. Amazon CloudFront


CloudFront is AWS’s Content Delivery Network (CDN).  

It speeds up website performance by caching your content closer to users globally.


🧭 6. Amazon Route 53


This is AWS’s DNS service — used for domain registration, routing, and health checks.  

It helps users connect to your website or app efficiently and securely.


🔐 7. AWS IAM (Identity and Access Management)


IAM controls access to your AWS resources.  

You use it to manage users, roles, and permissions safely — a key topic in both CLF-C02 and SAA-C03 exams.

💡 8. Amazon VPC (Virtual Private Cloud)


VPC lets you create a private network inside AWS.  

You define your own IP ranges, subnets, and routing — giving you full control over networking and security.


🧰 9. AWS CloudFormation


CloudFormation automates infrastructure deployment using templates.  

Instead of creating resources manually, you write a YAML or JSON file — and AWS builds it for you.


📊 10. Amazon CloudWatch


CloudWatch monitors your AWS resources and applications.  

You can track metrics, set alarms, and get insights into performance and costs.

🎯 Exam Tip


Most AWS exam questions describe a *scenario* — and you must identify which service solves the problem.  

So, don’t just memorize definitions — understand **how** and **when** to use each service.
