Introduction
Amazon Web Services (AWS) is the most extensive and widely used cloud platform globally, with over 200 fully-featured services available from data centers worldwide. AWS is used by millions of clients, including the fastest-growing startups, most prominent corporations, and top government agencies, to reduce costs, improve agility, and accelerate innovation.
Businesses have traditionally had to construct and maintain infrastructure to operate on-premises applications. Businesses may utilize the Software-as-a-Service (SaaS) model to consume applications hosted online, allowing them to cut costs by only paying for what they use, experience smooth and easy functionality updates, and seamlessly interface with their current data and systems.
Application Services
AWS offers a number of managed services that may be used with apps. The next section takes a high-level look into application services.
Amazon API Gateway
The Amazon API Gateway service is a fully managed service that allows developers to easily construct, publish, maintain, monitor, and protect APIs of any size. Organizations may develop an API that works as a "front door" for apps to access data, business logic, or functionality from back-end services like Amazon EC2 workloads, AWS Lambda code, or any web application. Traffic management, permission and access control, monitoring, and API version management are all handled by Amazon API Gateway while accepting and processing hundreds of thousands of concurrent API calls.
Amazon Elastic Transcoder
Amazon Elastic Transcoder is a cloud-based media transcoding service. It's intended to be a highly scalable and cost-effective means for developers and organizations to convert (or transcode) media files from their original forms into versions that can be played on mobile phones, tablets, and computers.
Amazon Simple Notification Service (Amazon SNS)
The Amazon Simple Notification Service (Amazon SNS) is a web service that organizes and coordinates the delivery of messages to recipients. There are two sorts of customers on Amazon SNS: publishers and subscribers, commonly known as producers and consumers.
Publishers connect with subscribers asynchronously by creating and sending messages to a topic, which serves as a logical access point and communication channel. When subscribers are subscribed to a subject, they consume or get the message or notification using one of the supported protocols.
Amazon Simple Email Service (Amazon SES)
Amazon Simple Email Service (Amazon SES) is a low-cost email service that allows businesses to send transactional emails, marketing messages, and other types of material to their consumers. Receiving messages and delivering them to an Amazon S3 bucket, calling custom code through an AWS Lambda function, and publishing notifications to Amazon SNS are possible with Amazon SES.
Amazon Simple Workflow Service (Amazon SWF)
Developers may use Amazon Simple Workflow Service (Amazon SWF) to create, run, and grow background tasks using parallel or sequential phases. Amazon SWF may be viewed as a cloud-based, fully managed state tracker and task organizer. Suppose your application's steps take more than 500 milliseconds to complete. In that case, it's critical to maintain the processing status and give the option to recover or retry if a job fails, according to established architectural patterns. Amazon SWF assists businesses in achieving this level of dependability.
Amazon Simple Queue Service (Amazon SQS)
Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that is quick, reliable, and scalable. Decoupling the components of a cloud application is straightforward and cost-effective using Amazon SQS. Organizations may use Amazon SQS to send any amount of data at any speed without missing messages or requiring other services to be constantly accessible.
