Amazon Web Services (AWS) is one of the most popular cloud platforms in the world, offering a vast ecosystem of cloud computing solutions. In this post, we'll explore the basics of AWS and some key services that every beginner should know about.


🎯 What is AWS?

AWS is a cloud computing platform by Amazon, offering on-demand services like compute power, storage, databases, and networking. These services allow businesses to reduce infrastructure costs, scale globally, and innovate faster. AWS is widely used by startups, enterprises, and developers for building, deploying, and managing applications in the cloud.


🛠️ Core AWS Services You Should Know

Here’s an overview of some fundamental AWS services, organized into common categories:

1. Compute Services

AWS offers various services to provide virtual machines and serverless computing:

  • EC2 (Elastic Compute Cloud):

    Virtual servers that you can configure to run your applications. You get control over the OS, CPU, and memory.

  • Lambda:

    A serverless service that runs your code in response to events. No need to manage servers; you’re only charged for the execution time.

  • ECS (Elastic Container Service):

    Orchestrate Docker containers efficiently with AWS.


2. Storage Services

AWS provides scalable storage solutions for data of any type and size:

  • S3 (Simple Storage Service):

    Store files and objects in the cloud with high availability. Ideal for backups, static websites, and big data.

  • EBS (Elastic Block Store):

    Block-level storage for EC2 instances, similar to hard drives.

  • Glacier:

    A low-cost storage service for long-term data archiving.


3. Database Services

AWS also offers managed databases to handle relational and non-relational data:

  • RDS (Relational Database Service):

    Fully-managed relational databases like MySQL, PostgreSQL, and SQL Server.

  • DynamoDB:

    A NoSQL database for fast and scalable applications.

  • Redshift:

    A data warehousing service for big data analytics.


4. Networking and Security

Security and networking are crucial for any cloud deployment:

  • VPC (Virtual Private Cloud):

    Create a logically isolated section of AWS to launch your resources.

  • CloudFront:

    A Content Delivery Network (CDN) to deliver content faster to users across the globe.

  • IAM (Identity and Access Management):

    Manage access to AWS resources securely with policies and permissions.


5. Monitoring and Automation

AWS provides tools to monitor resources and automate tasks:

  • CloudWatch:

    Monitor AWS resources and applications in real-time with alarms and logs.

  • CloudTrail:

    Track all API calls and user activity for auditing and compliance.

  • Elastic Beanstalk:

    Automate application deployment and scaling with minimal effort.
