What is AWS?

Amazon Web Services (or AWS) is a comprehensive cloud platform from the e-commerce giant Amazon. It provides software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). To understand AWS logic, think about the evolution of electricity supply.

Initially, factories built their own plants to supply their facilities. Over time, governments and private investors built large plants that would supply electricity to various cities, factories, and homes. With this new model, factories would pay much less per unit of energy, thanks to the economies of scale of large power plants. AWS was designed and grew based on similar logic.

In 2006, Amazon had positioned itself as the world's leading online retailer, a place it still maintains today. Continuous execution of such a massive operation required an extensive and sophisticated infrastructure. This provided Amazon with in-depth knowledge of managing large-scale networks and server systems.

Therefore, AWS was launched in 2006, when Amazon sought to make the technology infrastructure it had built and the knowledge it acquired available to businesses and individuals. AWS was one of the first pay-per-use (PAYG) computing models that could scale performance, storage, and computing based on changing customer needs.

Amazon Web Services provides cloud services for dozens of data centers and multiple Availability Zones (AZ) spread across regions of the world. Each AZ contains multiple data centers. Customers can configure virtual machines and replicate their data across multiple AZs for a highly resilient system that resists server or data center failure.

AWS services

Since its inception, AWS has become an essential cloud computing technology. Here are some of the essential AWS offerings:

• Amazon S3
• AWS Data Transfer Products
• Amazon EC2 (elastic computing cloud)
• Amazon SNS (Simple Notification Services)
• Amazon KMS (Key Management System)
• Amazon lambda
• Route 53

Amazon S3

This tool is used for Internet backup and is the cheapest storage option in the object storage category. The best part: You can retrieve stored data from almost anywhere when you need it.

AWS Data Transfer Products

As the name implies, these are migration, data collection, and data transfer products that help you collect data seamlessly. They also allow you to monitor and analyze data in real-time.

Amazon EC2 (elastic computing cloud)

This provides secure and scalable computing capacity, depending on your needs. The service is designed to make web-scale cloud computing more accessible.

Amazon SNS (Simple Notification Services)

This is a notification tool that delivers messages to large numbers of subscribers by email or SMS. You can send alarms, service notifications, and other messages designed to draw attention to important information.

Amazon KMS (Key Management System)

This is a security tool that uses 256-bit encryption for your data. It also protects you from hackers and cyber attacks.

Amazon lambda

This service executes your code depending on specific events and manages the dependent resources. You don't have to manage or provision servers, and how much you pay depends on how long it takes to run your code. It saves a lot of money compared to services that charge hourly rates.

Route 53

This is a cloud DNS service that does not require you to maintain a separate DNS account. It was designed to provide businesses with a reliable and cost-effective method of directing users to Internet applications.
