What are the most used AWS services?

Introduction

Amazon Web Services (AWS) is one of the leading cloud computing platforms used by businesses, developers, and organizations across the globe. What makes AWS stand out is not just the sheer number of services it offers but also how widely and reliably those services are used. From hosting websites to managing data, AWS certification course in Chandigarh offers tools that fit nearly every IT need. For someone new to the cloud or exploring AWS, it can be helpful to know which services are used most frequently and why they are essential. In this article, well explore the most popular AWS services and how they support modern digital infrastructure.

Why Some AWS Services Are More Popular Than Others?

While AWS provides over 200 cloud services, not all are used equally. The most popular ones tend to be:

• Simple to set up and manage
  
  

• Cost-efficient and scalable
  
  

• Flexible across industries
  
  

• Essential for everyday cloud computing tasks
  
  

These services are often the foundation for cloud infrastructure, web hosting, machine learning, security, and application development.

1. Amazon EC2 (Elastic Compute Cloud)

EC2 is perhaps the most widely used AWS service. It allows users to launch and manage virtual servers, also known as instances, in the cloud.

Why EC2 is popular:

• Flexible pricing and instance types
  
  

• Ideal for web hosting, app servers, and backend systems
  
  

• Supports multiple operating systems
  
  

• Scalable from a single instance to thousands
  
  

Its often considered the engine that powers many cloud-based applications.

2. Amazon S3 (Simple Storage Service)

S3 is a highly durable and scalable storage service that allows users to store any amount of data at any time.

Key Use Cases:

• Backup and recovery
  
  

• Hosting static websites
  
  

• Media storage (videos, images, files)
  
  

• Application data storage
  
  

Why S3 stands out:

• 99.999999999% durability (11 nines)
  
  

• Easy file management with buckets
  
  

• Integration with many other AWS tools
  
  

S3 is a go-to solution for businesses that need secure, reliable storage without managing hardware.

3. Amazon RDS (Relational Database Service)

RDS is a managed service for running relational databases like MySQL, PostgreSQL, SQL Server, and Oracle.

Advantages of RDS:

• No need to manage database software manually
  
  

• Automated backups, updates, and scaling
  
  

• High availability and multi-zone replication
  
  

It's used heavily by developers who want to focus on their applications instead of database administration.

4. AWS Lambda

Lambda is a serverless computing service that lets you run code without provisioning servers.

Why Developers Love Lambda:

• Pay only for the compute time you use
  
  

• No server maintenance required
  
  

• Great for event-driven tasks (e.g., image processing, data pipelines)
  
  

• Integrates well with other AWS services like S3, DynamoDB, and API Gateway
  
  

Its perfect for microservices, automation, and building lightweight cloud-native applications.

5. Amazon CloudFront

CloudFront is a content delivery network (CDN) that delivers data, videos, and web pages with low latency and high transfer speed.

Benefits of CloudFront:

• Global edge locations for fast delivery
  
  

• Reduces load on your origin server
  
  

• Works well with S3, EC2, and custom applications
  
  

• Built-in DDoS protection
  
  

Web applications and media-heavy platforms use CloudFront to improve performance and user experience globally.

6. AWS IAM (Identity and Access Management)

IAM is critical for managing user access and permissions across AWS resources.

Why IAM is essential:

• Controls who can access what in your AWS environment
  
  

• Supports multi-factor authentication (MFA)
  
  

• Offers detailed permission control with policies and roles
  
  

• Enhances security for teams and organizations
  
  

IAM is often one of the first services set up in any AWS environment to ensure secure access control.

7. Amazon DynamoDB

DynamoDB is a fully managed NoSQL database known for its performance and scalability.

Why Its Popular:

• Handles millions of requests per second
  
  

• Ideal for mobile apps, gaming, and IoT
  
  

• Serverless and auto-scaling
  
  

• Easy integration with AWS Lambda
  
  

DynamoDB is chosen when fast, flexible, and scalable data storage is needed without complex setup.

8. AWS CloudWatch

CloudWatch is a monitoring service used to track metrics, logs, and events in your AWS environment.

What It Helps With:

• Detecting unusual behavior
  
  

• Setting up alarms and auto-scaling triggers
  
  

• Logging errors and performance issues
  
  

• Monitoring application health
  
  

For any business running applications on AWS, CloudWatch provides the visibility needed to maintain performance and uptime.

9. AWS Elastic Load Balancing (ELB)

ELB automatically distributes incoming traffic across multiple targets (like EC2 instances).

Benefits of ELB:

• Improves application availability
  
  

• Supports auto-scaling
  
  

• Works with both public-facing and internal applications
  
  

When building scalable systems, ELB is key for handling large volumes of traffic without failure.

10. AWS Route 53

Route 53 is a DNS (Domain Name System) web service used to manage domain names and routing.

Why It's Commonly Used:

• Easy to register and manage domains
  
  

• Reliable and fast domain routing
  
  

• Integrated with other AWS services
  
  

• Supports health checks and routing policies
  
  

For businesses needing website routing or custom domain management, Route 53 is the go-to tool.

Conclusion

AWS provides a powerful set of services, but the most commonly used ones are those that solve fundamental business problems from compute and storage to database management and security. Whether you're hosting a website, building an application, or processing big data, these services offer a solid, scalable foundation. Understanding the most used AWS services helps beginners prioritize their learning and professionals design efficient cloud architectures. By focusing on services like EC2, S3, Lambda, RDS, and IAM, you can get the most out of AWS and confidently build solutions that work reliably in the cloud.
