Top List of AWS Services in 2025 - AWS PASS, IAAS and SAAS Services List

Introduction

The AWS (Amazon Web Services), is a cloud-based platform with many features and services, that provides cost-effective computing solutions. A cloud service system offers faster access to adaptable and minimal-cost IT resources that can be used to build and maintain software and databases, as well as create user-friendly software applications. No need of investing in hardware and spend a lot of time managing that hardware. The user can quickly access as many resources as needed and only pay for those resources used. The cloud computing model is based on on-demand, pay-as-you-go access to services. AWS is such a type of service. In AWS the IT infrastructure is configured as per the user requirements. The list of AWS services explains the services applicable to various cloud computing solutions.

AWS Services Overview

Cloud computing is the on-demand delivery of online services such as servers, databases, and software to users. Data storage on local machines is no longer necessary with cloud computing as virtual servers are being used which in turn stores the data on the Cloud. It allows you to access data stored on a remote server and it is used to store and access data from the global level. AWS services overview has been provided in the sections that follow.

AWS Serverless Scenario

AWS Serverless Application Mode (AWS SAM), is a serverless framework for developing applications. It allows the programmer to express functions, APIs, databases, and event source mappings using abbreviations syntax. The developer can define and model the application needed for the instance, with a few lines per resource. SAM translates SAM syntax into AWS CloudFormation syntax during deployment and executes quickly. The AWS SAM CLI can be used to get started in building SAM-based applications. SAM CLI is the command line interface applicable for building, testing, and debugging applications defined by SAM templates or the AWS Cloud Development Kit locally (CDK).

Loosely Couple Architecture of AWS

A loosely coupled architecture entails the execution of so many simple jobs. Smaller jobs usually run on a single node, consuming either one process or multiple processes with shared memory parallelization (SMP) for parallel processing inside that node. The simulation's concurrent processes, or repetitions, are post-processed to produce a single solution or discovery. Many areas use loosely coupled applications, such as Monte Carlo simulations, image processing, genomics analysis, and Electronic Design Automation (EDA). In a loosely coupled workload, the loss of one node or job usually does not cause the entire calculation to be delayed. The lost work may be completed later or excluded entirely. The configuration and efficiency of the nodes involved in the calculation can vary.

AWS Cloud Computing Models

There are mainly three models used those are IaaS, PaaS, and SaaS:

Infrastructure as a Service (IaaS)

Infrastructure as a Service, or AWS IaaS services list, includes the services, essential for building the blocks of cloud technology and provides consistent access to networking functionalities, virtual or dedicated computers, and storage space. Infrastructure as a Service gives the developer the most flexibility and management control over the resources. These services are almost similar to existing IT resources and many IT developers are already familiar.

Platform as a Service (PaaS)

Platform as a service completely eradicates the demand for companies to maintain the core infrastructure (typically hardware and operating systems), enabling you to concentrate on application deployment and maintenance. It thus helps to make the developer more productive since they do not need to bother about other operations. The AWS PaaS Services list the functions such as resource acquisition, configuration management, updating software, bug fixing, and any indistinct legwork related to running the application.

Software as a Service (SaaS).

Software as a Service offers a finished product that is operated and managed by the service provider. The user has to think about how to use that specific piece of software. A common example of a SaaS application is web-based email, which allows you to send and receive email without having to manage feature additions to the email product or maintain the servers and operating systems that the email program is running on.

AWS list of Services

The following list of AWS services covers almost all AWS Core essential services:

AWS IAM

This service provides access to AWS and resources securely. This service enables the creation of users, and groups, and allows permissions to access the resources.

EC2

EC2 stands for Elastic Cloud Compute. It is used to build virtual machines in the Cloud. The operating system in the virtual machine can be any popular OS such as Windows, Linux, macOS, and so on.

Amazon VPC

Amazon Virtual Private Cloud is the service that segregates the entire software infrastructure from outside exposure to prevent unauthorized access.

Amazon CloudFront

It is a global Content Delivery Network (CDN) service that provides support to improve website speed as well as data access from the cloud with minimal latency.

Amazon S3

Simple Storage Service or Amazon S3 is a highly secure and redundant file storage service. It belongs to the AWS storage services list. The data is saved in the 3 data centers of AWS with access from any data center. This is to maintain data flexibility without latency. When some failure happens to one of the data centers, then the data can be accessed from the other data center.

AWS Lambda

AWS Lambda is an event-driven, serverless compute service provided by Amazon Web Services that computes the code according to the event and also organizes the resources automatically, removing the need for the user to manage the resources required to execute the code.

Amazon RDS

Relational Database service RDS is a service that helps to develop dedicated databases, and user-friendly software infrastructures. It also supports popular database engines such as SQL Server, MySQL, PostgreSQL, and so on. UAWS Lambda

Amazon SNS

Simple Notification Service SNS is an event-driven service to automate the sending of messages from the Cloud. This service provides a low-cost infrastructure to carry out the mass delivery of messages to users of any platform.

Amazon SQS

Amazon Simple Queue Service (Amazon SQS) provides a hosted queue that is secure, durable, and obtainable. This service integrates and disconnects the distributed software systems and components. Amazon SQS includes standard frameworks like dead-letter queues and cost allocation tags. It offers a standard web services API that can be accessed using any programming language supported by the AWS SDK.

Amazon ELB

Amazon Elastic Beanstalk or ELB is the service that helps with the automatic creation of websites. It is useful for developers to avoid barriers in writing algorithms, codes, etc. It is capable of executing functions such as load-balancing, autoscaling, and so on.

AWS CloudFront

Amazon CloudFront is a service that improves the speed of the delivery of static and dynamic web content to users. CloudFront distributes the content using a vast network of edge data centres. When a user requests content served by CloudFront, the request is routed to the edge location with the lowest latency, ensuring that the content is delivered as quickly as possible. CloudFront delivers content instantly if the specified content is already available at the edge location with the lowest latency.

AWS Security Services

AWS security service list includes services for Identity and access management, detection and response services, Network and application protection services, and automated compliance checks

AWS Migration Services

AWS migration services list consists of the services for cloud migration. It quickly makes the developer understand the benefits of cloud migration.

AWS Storage Services

These include the services required for industry-leading adaptability, accessibility of information, protection, and effectiveness.
