What is Cloud Computing?
Cloud computing is a term that refers to the delivery of IT resources over the Internet. Cloud computing allows you to access various services such as computing, storage, networking, databases, analytics, and more without having to invest in or manage physical infrastructure. Cloud computing can help you reduce costs, increase scalability, improve performance, and enhance security.
What is AWS?
One of the most popular and widely used cloud computing platforms is Amazon Web Services (AWS). AWS is a subsidiary brand from Amazon which specializes in providing on-demand cloud computing services along with APIs to companies, governments and even individuals across the globe. This service is charged on a pay-as-you-go basis. AWS offers over 200 fully featured services from data centers globally. Clients can use AWS in combination with autoscaling to use more computing in times of high application usage and scale down to reduce costs when there is less traffic. In this blog, we will introduce you to some of the basic concepts and benefits of cloud computing and why cloud computing is used in AWS. We will also show you how to get started with AWS and explore some of the most common and useful cloud services that AWS provides.
Getting Started with AWS Cloud Computing Services
To get started with AWS, you need to create an AWS account. You can sign up for a free account that gives you access to the AWS Free Tier. The AWS Free Tier allows you to use certain services for free up to a certain limit of 12 months. For example, you can use Amazon EC2 (Elastic Compute Cloud), which is a service that lets you launch virtual servers in the cloud, for free up to 750 hours per month for 12 months.

- Choose your support plan (basic, developer, business, or enterprise) and click on Complete Sign Up.
By following these steps you can now create your AWS account and access the AWS Management Console. The AWS Management Console is a web-based interface that allows you to manage your AWS resources and cloud services.
Exploring Cloud-based AWS Services:
AWS offers a wide range of services for different purposes and domains. Some of the most common and useful services are:
- Amazon EC2: This service allows you to launch virtual servers in the cloud. You can choose from different types and sizes of instances (virtual machines) that suit your needs. You can also configure various aspects of your instances such as security groups, key pairs, storage volumes, network interfaces, etc.
- Amazon S3: AWS also allows you to store and retrieve large amounts of data across the web on any platform. You can create buckets (containers) and objects (files) in S3 and access them using a unique URL. You can also control access permissions, encryption options, and lifecycle policies, among others.
- Amazon RDS: This service allows you to set up, operate, and scale relational databases in the cloud. You can choose from different database engines such as MySQL, PostgreSQL, Oracle, SQL Server, etc. You can also benefit from features such as automated backups, replication, encryption, monitoring, etc.
- Amazon DynamoDB: This service allows you to create and manage NoSQL databases in the cloud. You can store and query data using key-value pairs or document structures. You can also benefit from features such as high availability, scalability, performance, consistency, etc.
- Amazon Lambda: This service enables code runtime or server management infrastructure. You can write your code in any supported language such as Python, Node.js, Java, etc., and upload it to Lambda. You can also trigger your code from various events such as HTTP requests, S3 events, DynamoDB streams, etc.
These are just some of the many services that AWS offers. You can explore more services and learn how to use them by following the tutorials and documentation that AWS provides.
Why is Cloud necessary in AWS?
Cloud computing is necessary for AWS because it provides a number of benefits, including:
