The Top Reasons to Use AWS

AWS is a cloud platform that offers a wide range of services, from basic infrastructure and storage to AI and analytics tools.

AWS has built a reputation among developers over the years. It gives teams the tools to handle everything from setting up basic infrastructure to running complex applications. The platform lets you create, test, and deploy applications without buying extra hardware or software. With services like EC2 instances, load balancers, S3 buckets, and Lambda, you can spin up resources on demand and only pay for what you use.

So why do so many companies end up on AWS? Here’s a look at some of the main reasons.

Cloud services: A bit of history

Cloud computing became viable in the 1960s when computers started moving away from bulky mainframes toward smaller, remote servers.

AWS is one of the longest-running cloud platforms. It offers storage, networking, analytics, and plenty more. Virtualization technology lets you deploy applications faster and more cheaply than traditional infrastructure. AWS also provides high availability, strong security, and data protection.

Pricing varies based on region, usage, capacity, and the services you need. That flexibility is part of why AWS stands out from competitors.

Characteristics of AWS

• AWS is a cloud computing platform with storage, computing, and networking services.
• It serves everyone from small businesses to large enterprises.
• You pay only for what you use, making it cost-effective for scaling.
• It has multiple layers of security to protect your data.

What is cloud computing?

Cloud computing means accessing shared computing resources—servers, storage, networks, applications—over the internet without managing physical hardware yourself.

You get computing on demand, without dealing with the complexity of maintaining your own network or server room. The ability to deliver data quickly and reliably makes cloud computing practical for most businesses.

Types of cloud services

Cloud services fall into three main categories:

• Infrastructure as a Service (IaaS) — Virtual machines and networking you configure yourself
• Platform as a Service (PaaS) — A ready-to-use development environment with OS, middleware, and tools
• Software as a Service (SaaS) — Complete applications running in the cloud that you access directly

IaaS gives you virtualized hardware and lets you spin up VMs on demand. You pay based on compute power and duration. You can scale up or down whenever you need.

PaaS provides the virtual resources plus the software stack—operating system, middleware, development frameworks, and a database management system. You focus on building, not managing the underlying infrastructure.

SaaS means using a complete software product (like a CRM, office suite, or accounting tool) that runs on the provider’s servers. No local installation, no access to the underlying infrastructure—you just use the service.

When to choose AWS

AWS works for startups and large organizations alike. Whether you’re running a small website or migrating a whole data center, AWS has services that fit. It offers everything from RoboMaker (for robotics) to Lightsail (a simple virtual private server for basic workloads).

AWS now provides some of the highest compute and storage options available. It has 136 virtual machine types across 26 families, handling workloads from small web apps to the largest HPC and SAP environments.

Machine learning and AI

For ML and AI workloads, AWS offers GPU-enabled virtual machine types with high-end configurations. If you need a physical server for compliance reasons, Bare Metal-as-a-Service is available. For virtualized workloads, features like placement groups let you control which hardware your computing and storage run on.

One thing to note: AWS doesn’t support custom VM sizes. It provides fixed configurations rather than letting you dial in exact vCPU and RAM combinations. Unlike some cloud providers, AWS doesn’t bundle GPUs into every VM family—you can only get GPUs with specific instance types.

Cloud storage on AWS comes with options like dynamic resizing and different disk types (standard and SSD). Unlike some competitors, AWS doesn’t cap IOPS based on disk size. Pay more and you get more IOPS, even on smaller disks.

Relational database services

AWS supports managed databases for MySQL, PostgreSQL, MariaDB, Oracle, and MS SQL through RDS. It also offers Aurora—AWS’s own MySQL- and PostgreSQL-compatible databases with Oracle-like performance at a fraction of the cost. AWS has been investing heavily here, with Multi-Master and serverless versions in development.

For NoSQL databases, DynamoDB has been AWS’s offering for about five years, evolving from their earlier SimpleDB. AWS also provides Neptune (graph databases) and ElastiCache (caching for key-value data).

Networking

AWS built its networking portfolio over time. It started with VPC (Virtual Private Cloud) and related features like security groups, network ACLs, and access gateways. Early on, users still had to set up their own NAT servers and firewalls. AWS kept adding managed services based on customer feedback—now it offers NAT Gateway, VPN Gateway, Transit Gateway, Direct Connect Gateway, and a VPN client service. No need to deploy OpenVPN servers just to access your cloud VMs.

Network security

AWS provides managed services for DDoS protection (AWS Shield), a web application firewall (WAF), and tools like Inspector, Config, and CloudTrail for inventory, policy management, and auditing. GuardDuty handles threat detection.

Data security

AWS encrypts most storage services by default. It offers key management through KMS and CloudHSM. Macie uses AI for data loss prevention.

Queuing, messaging, and notifications

For queuing and messaging, AWS has Amazon MQ (AMQP-enabled) and SQS. For streaming, it offers Kinesis and a managed Kafka service. SNS handles multi-channel notifications—SMS, mobile push, email—and integrates with other AWS services for loosely coupled, event-driven architectures.

AWS serves U.S. government customers through GovCloud regions. Customers needing to operate in China can use the AWS China region, operated through third-party partners.

Wrapping up

Cloud services help organizations save time and work more efficiently.

AWS is one of the biggest cloud providers with an enormous product catalog. It offers scalability, performance, reliability, and flexibility while cutting costs for infrastructure maintenance.

With fast provisioning, a usable interface, solid support, and global reach, AWS works well for businesses of all sizes looking for a cloud platform that fits their needs.
