What is AWS used for?

AWS is used to run applications, store data, analyze information, build artificial intelligence solutions, and back up critical systems, without investing in hardware upfront. Companies use it to grow fast, gain availability, and pay as they go.

What are the main AWS services?

The most widely used are compute (on-demand servers and serverless functions), object storage, managed databases, networking and security, and data and AI services. Almost any solution is built from these building blocks.

How does a company get started with AWS?

The safest path is to work with an AWS partner that designs the architecture, sets up security from the start, and guides adoption or migration. That avoids costly mistakes and makes the most of the platform from day one.

AWS is not free, but it offers a free tier designed for trying the platform: more than thirty services that are always free within monthly usage limits, plus an initial exploration plan with time-limited credits for new accounts. It works well for learning and prototyping. For real business use, the model is pay-as-you-go, billed in US dollars, and it is worth sizing the spend before starting.

What Is AWS? Meaning and Clear Guide

Q: What is AWS in simple terms?

AWS (Amazon Web Services) is Amazon's cloud computing platform. Instead of buying and maintaining its own servers, a company uses AWS infrastructure over the internet —compute, storage, databases, and more— and pays only for what it consumes.

Q: Why do companies choose AWS?

For its breadth of services, its maturity in security and compliance, its global presence of regions, and its pay-as-you-go model. That lets you start small, scale when needed, and turn large capital investments into operating expense.

Q: What does the acronym AWS stand for?

AWS stands for Amazon Web Services. It is Amazon's cloud computing division, launched in 2006, and today it is a business in its own right, separate from the e-commerce operation it grew out of. When someone says "we are on AWS", they mean their systems run on that platform.

AWS (Amazon Web Services) is Amazon’s cloud computing platform: a set of infrastructure and software services that companies use over the internet to run their applications, store their data, and build solutions, without having to buy or maintain their own servers. It is the most widely used cloud in the world and the foundation on which many organizations modernize their technology.

What does the acronym AWS stand for?

AWS stands for Amazon Web Services, the cloud computing division Amazon launched in 2006. Today it is a business of its own, separate from the e-commerce operation it grew out of, and the most common reference point when people talk about the cloud in a business context.

What exactly is AWS?

Traditionally, a company that needed to run a system had to buy servers, install them in a data center, maintain them, and replace them periodically. That means a large upfront investment and a team dedicated to caring for that hardware.

AWS changes that model. Instead of owning the infrastructure, the company uses it as a service: it turns on the resources it needs, uses them for as long as required, and pays only for what it consumes. Amazon takes care of the data centers, the power, the hardware, and its maintenance; the company focuses on its product and its business.

What problem does the AWS cloud solve?

The big shift is moving from owning infrastructure to consuming it on demand. That solves several common pain points:

The upfront investment stops being a barrier. There is no need to guess how much hardware to buy for the coming years; you start small and grow with real demand.
Capacity adjusts on its own. When a traffic spike arrives —a campaign, a month-end close— resources scale up; when it drops, spending drops too.
Time to market shrinks. Spinning up a new environment takes minutes instead of weeks of purchasing and configuration.

Main AWS services

AWS offers hundreds of services, but almost any solution is built by combining a few fundamental blocks:

Compute: on-demand virtual servers and serverless options that run code without managing machines.
Storage: durable, scalable storage of files and objects, ideal for backups, content, and application data.
Databases: managed engines —relational and non-relational— where AWS handles backups, patching, and high availability.
Networking and security: private networks, access control, encryption, and secure connectivity between the company’s systems and the cloud.
Data and artificial intelligence: services to analyze information, build a data lake, and create generative AI solutions.

Why do companies choose AWS?

Beyond the number of services, there are deeper reasons:

Maturity in security and compliance. AWS maintains international certifications and tools that help meet each industry’s regulations, which is decisive in regulated sectors such as banking, insurance, or healthcare.
Global presence of regions. Infrastructure is distributed across regions around the world, which makes it possible to bring applications closer to users and design disaster-recovery plans.
Pay-as-you-go model. You are billed in US dollars for what you actually consume, which turns large capital investments into predictable operating expense.
Ecosystem and community. A broad network of partners, documentation, and certified talent makes it easy to find expert support.

Where does AWS run for companies in Peru?

For clients in Peru and Chile, the most used region is AWS Virginia, for its direct fiber link and broad service catalog; and AWS has already announced the AWS Santiago region in Chile, which will make it possible to keep data closer once it goes live. The region is chosen based on latency, cost, and the compliance requirements of each project.

Beyond the regions, AWS operates a local zone in Lima for workloads that demand very low latency for Peruvian users — a case of edge computing worth evaluating when response speed directly affects the business. You can see how we work each market in our presence in Peru.

AWS as a foundation to grow

Adopting AWS is rarely just “moving servers to the cloud.” Done well, it is the opportunity to put security in order, gain availability, and open the door to application modernization and advanced analytics. That is why the first step matters as much as the destination.

At Caleidos we support that journey as a cloud consultancy and AWS partner, with a portfolio of services that spans from strategy and migration to continuous operation, and with cases in production documented in our case studies.
