What is AWS?

The complete cloud computing platform provided by Amazon is called Amazon Web Services (AWS). It offers a wide variety of scalable and adaptable services made to make it simple for organizations to develop and implement apps and services. Computing power, storage, databases, networking, analytics, machine learning, and other services are all part of AWS’s comprehensive service offering. 

Why learn AWS?

Learning from the Amazon Web Service course has many advantages and is very beneficial for both people and businesses. Here are a few strong arguments for learning AWS:

  1. Career Advancement: Companies across sectors are quickly embracing AWS, the top cloud service provider. Your career chances can be greatly improved by having AWS skills and certifications, which can lead to a variety of job options in cloud architecture, development, operations, and more.
  2. Industry Standard: AWS is now accepted as the benchmark for cloud computing. Your ability to work with the most popular cloud platform will increase as a result of your understanding of AWS, making you a desirable asset on the job market.
  3. Flexibility and Scalability: AWS provides a wide range of services that let companies adjust their infrastructure according to demand. You may use these services to create and construct very scalable, adaptable, and affordable solutions by learning AWS.

What is Serverless Computing?

Developers may concentrate only on building and delivering code using the serverless computing cloud computing approach, which eliminates the need to maintain underlying servers. In this approach, server provisioning, scalability, and infrastructure upkeep are handled by the cloud provider, such as AWS Lambda. Developers may respond to events by executing their code in a serverless environment, with the cloud provider handling the resource allocation depending on demand automatically. 

Since customers only pay for the actual computing time and resources used, serverless computing has benefits including decreased operational overhead, greater scalability, and cost optimization. It makes it possible for developers to create highly scalable, event-driven apps without having to deal with server administration.

Serverless Computing with AWS

AWS’s serverless computing paradigm enables developers to create and deploy apps without worrying about maintaining infrastructure or servers. AWS provides a full range of serverless services, with AWS Lambda serving as the foundation.

  • AWS Lambda: AWS Lambda is a computing service that executes your code in response to events like modifications to a DynamoDB table or changes to data in an Amazon S3 bucket. Without installing or managing servers, you may create code in a variety of computer languages and run it using Lambda. In response to incoming requests, Lambda automatically scales your code, delivering excellent availability and performance.
  • API Gateway: For your serverless apps, creating, publishing, and managing APIs is simple with AWS API Gateway, a fully managed service. It serves as a front door for your APIs, including functions such as caching, authentication, and authorization. You may build RESTful APIs or WebSocket APIs to communicate with your serverless functions using API Gateway since it integrates with AWS Lambda without any issues.
  • AWS DynamoDB: A NoSQL database service called DynamoDB offers serverless applications with quick and scalable storage. It enables easy connection with Lambda and allows for the highly available and long-lasting storage and retrieval of data. Because of its adaptable data schema and built-in scalability, DynamoDB is a great option for serverless applications with a range of workloads.
  • Step Procedures: AWS You may create serverless processes and coordinate many AWS services with Step Functions. You may use it to graphically create and carry out complicated processes, specifying the order of the stages and taking care of error management and retries. Step Functions’ integration with Lambda, API Gateway, and other services gives serverless application orchestration a strong tool.
  • AWS EventBridge: Serverless applications may respond to events from many sources inside the AWS environment thanks to the event bus service EventBridge. By enabling you to specify event rules and route events to destinations like Lambda functions, SNS topics, or Step Functions, it supports event-driven architectures. The serverless application’s many components may communicate with one another seamlessly thanks to EventBridge, which makes event-driven architectures simpler.

Benefits of Serverless Computing with AWS

  1. Scalability: Using AWS serverless services, your applications are scaled according to demand, allowing you to handle any workload without worrying about setting up or managing servers.
  2. Cost-Effectiveness: With serverless computing, costs are optimized, and operational overhead is decreased because you only pay for the actual computing time and resources used by your applications.
  3. Simplified Management: By handling infrastructure management tasks like patching, scaling, and availability, AWS frees up developers to concentrate on building code and adding value.
  4. Agility and Time-to-Market: By allowing developers to quickly iterate and release code changes without the requirement for infrastructure setup, serverless computing with AWS offers shorter development cycles and shorter time-to-market.
  5. Integration and Ecosystem: Serverless options are effortlessly integrated with AWS’s vast ecosystem of services. Your serverless apps may benefit from a variety of AWS services, including AI/ML, databases, communications, and analytics.


In the field of application development, serverless computing has emerged as a game-changer, and AWS provides a full range of services to embrace this paradigm shift. You can design and deploy apps without worrying about infrastructure maintenance with AWS Lambda, API Gateway, and other serverless services. Serverless architecture is an appealing option for companies of all sizes because of the auto-scaling features, pay-per-use pricing, and seamless connection with other AWS services.
