AWS Serverless Platforms
We Work With

AWS serverless eliminates infrastructure management entirely — you write the code, and AWS provisions, scales and patches everything underneath it. Organisations that adopt it typically cut infrastructure costs by 40-70% versus traditional server-based hosting.

AWS Fargate

We pair Fargate with services like ECS and EKS to remove the need to provision, patch or manage servers — you enable and pay for resources per application, with isolation built in by design for stronger security.

AWS Lambda

Through this event-driven compute service we build pay-as-you-go workloads, workload-aware scaling logic and precise event integrations without ever managing a server. Lambda processes trillions of requests every month.

Choosing the right architecture

Serverless vs Traditional Cloud
vs Containers

Cloud architecture choice affects cost, scalability and delivery speed — here's how serverless compares to EC2-based hosting and container orchestration.

Factor AWS Serverless (Lambda / Fargate) Traditional Cloud (EC2) Containers (ECS / EKS)
Server Management None — fully managed by AWS Full server management required Container orchestration required
Pricing Model Pay only per execution (millisecond billing) Pay 24/7 whether idle or busy Pay for running container capacity
Auto Scaling Instant, automatic, virtually unlimited Manual or scheduled autoscaling Configurable autoscaling
Deployment Speed Seconds to deploy new functions Minutes to hours for provisioning Minutes per container build/deploy
Best For Event-driven apps, APIs, microservices, variable traffic Long-running, heavy compute workloads Complex microservices needing full control
Cost Efficiency Up to 70% lower operational costs Higher ongoing infrastructure cost Moderate cost
Connecting every layer

AWS Serverless Integration
Services

Application integration on AWS serverless is what connects each decoupled piece of your application together — here's what we reach for most.

Amazon EventBridge

A serverless event bus that connects applications, blending real-time data from your own services, SaaS apps and AWS services into one stream.

AWS Step Functions

A serverless function orchestrator that sequences Lambda functions and AWS services into reliable, visualised business workflows.

Amazon SQS

A message queuing service that helps decouple and independently scale serverless applications, microservices and distributed systems.

Amazon SNS

A fully managed messaging service enabling application-to-person and application-to-application communication at scale.

Amazon API Gateway

Gives your programmers a scalable, secure backend for mobile and web applications, so front-end and back-end teams can link up cleanly.

AWS AppSync

Helps build GraphQL APIs quickly, giving front-end developers the ability to query multiple databases and services through a single endpoint.

Where your data lives

AWS Serverless
Data Store Services

We build serverless services across every layer of your stack, including the data layer that needs to scale exactly the way your compute does.

Amazon S3

Cloud storage for any volume of data, letting your serverless functions read and write objects without managing a single disk.

Amazon DynamoDB

A NoSQL database service that lets us stand up tables handling any level of requested traffic without capacity planning.

Amazon RDS Proxy

A fully managed database proxy for Amazon RDS that makes serverless apps more scalable, resilient to failures, and better protected.

Amazon Aurora Serverless

An on-demand, auto-scaling database configuration that starts up, shuts down and scales capacity automatically as your app needs it.

Why teams go serverless

Top Benefits of
Serverless App Development

Serverless architecture changes the economics and speed of shipping software — here's what our clients see most often.

Pay Per Usage

Millisecond-level billing means you're charged only for the compute time your functions actually consume, not idle capacity.

Effortless Deployment

New functions ship in seconds through automated pipelines, so features and fixes reach production far faster than server-based releases.

No Server Management

AWS handles provisioning, patching and availability, so your team spends its time on application logic instead of infrastructure upkeep.

Higher Scalability

Functions scale from zero to thousands of concurrent executions automatically, handling traffic spikes without manual intervention.

Cost Savings

Removing idle infrastructure typically cuts operational costs by 40-70% versus always-on, traditional server-based hosting.

Reusable Components

Functions and integration layers are built to be shared across projects, so new applications reuse proven, tested building blocks.

★★★★★
Large scale MongoDB development delivering multi type content within complex collections with embedded typing and logic and in multiple languages on AWS. Technically complex but delivered faultlessly. Thanks everyone at Eternal, job very well done!
Richard P.Bournemouth, GB
★★★★★
The Eternal team did an excellent job setting up our application. It was a complex scenario with several legacy issues, but they worked swiftly and communication was excellent, all managed through a very helpful online project management system. I will definitely be using them again in the future
David H.Leeds, GB
★★★★★
Great team to work with, they fixed a very difficult problem which 5 other coders could not figure out. They did in an hour. Amazing team, will hire again for future projects.

Common questions

FAQs on AWS Serverless
App Development

Q

What are serverless applications in AWS?

Serverless applications in AWS are cloud-based applications where AWS manages the underlying infrastructure automatically. Developers write code using services like AWS Lambda, Amazon API Gateway and Amazon DynamoDB without provisioning or maintaining servers. These applications scale automatically, improve availability, and charge only for actual usage.

Q

What are the five major components of serverless development?

The five major components are a web server, a Function-as-a-Service (FaaS) layer such as AWS Lambda, a security token service (STS), user authentication, and a database such as Amazon DynamoDB or Aurora Serverless.

Q

Which company provides the best AWS serverless development services?

Eternal Web Pvt Ltd is a leading AWS serverless application development company with 15+ years of experience, 15+ AWS certified developers and 99+ happy clients globally — offering end-to-end serverless solutions using AWS Lambda, Fargate, API Gateway and DynamoDB across the US, UK and India.

Q

What are the use cases for serverless development?

Common use cases include trigger-based tasks, RESTful APIs, asynchronous processing, security checks, continuous integration and delivery, real-time data processing, chatbot backends and IoT event handling.

Q

What are the future aspects of serverless computing?

Serverless computing is the modern trend in cloud architecture, making it far simpler to build, deploy and scale apps. Developers can focus purely on their code, without provisioning servers or installing software to run it.

Q

Can a serverless app be completely automated?

Yes — serverless applications can be fully automated using AWS Lambda and AWS CodePipeline, enabling continuous delivery, infrastructure as code with AWS CloudFormation or CDK, and zero-downtime deployments.

Q

What is the difference between microservices and serverless?

Microservices is an architectural pattern where applications are built as independently deployable services, often in containers. Serverless is an execution model where a cloud provider runs your code in response to events without managing servers. Microservices define how you structure your app; serverless defines how you run it.

Q

How much does AWS serverless app development cost?

Cost depends on project scope, team size and engagement model. Eternal offers flexible hiring — hourly, part-time or full-time dedicated developers — while the underlying pay-per-use infrastructure can reduce operational costs by 40-70% compared to traditional hosting.

Q

What is the difference between AWS serverless and traditional cloud hosting?

Traditional cloud hosting requires you to provision, manage and pay for servers 24/7, even during idle time. AWS serverless eliminates server management entirely — you only pay for actual compute time, and applications auto-scale instantly with no idle cost.

Q

What industries benefit most from AWS serverless architecture?

Hotel and Wellness, Manufacturing, Finance, Real Estate, Logistics and Distribution, Jewellery, Travel and Hospitality, and Lighting all benefit — as does any industry with variable traffic or event-driven workflows.
