AWS Essentials - Part 9 [ Application Services in AWS Cloud ]

AWS Application services have a broad range of services that helps in enhancing the rendering of the application overcloud. Main offerings include -

Amazon Elastic Transcoder - Simple Scalable Media Transcoding Amazon API Gateway - Build, Deploy, and Manage APIs AWS Step Functions - Coordinate Distributed Applications

 Step Functions

Offers a graphical console to set up and visualize the components of the application as a series of steps.

• Easy to create and run multi-step applications.
• Coordinate the components of microservices and distributed applications using visual workflows.
• Create applications from single components that each perform a discrete function to change and scale applications quickly.
• Triggers and tracks each step automatically, and retries when errors are noticed, which ensures your application executes as intended and in order.
• Logs the state of every single step. When things go wrong, it is simple to diagnose and debug issues fast. You can change and include steps without the need to write code, effortlessly evolve the application and innovate rapidly.
• Manages the underlying infrastructure and operations to ensure the application is available at all scales.

API Gateway

Fully managed service that allows developers to create, publish, maintain, monitor, and secure APIs easily at any scale.

• Serves as a “front door” for applications to access functionality, data, or business logic from your back-end services, like, code running on AWS Lambda, workloads running on Amazon EC2, or any Web application.
• Takes care of processing and accepting of concurrent API calls, including API version management, monitoring, traffic management, and authorization and access control
• Pay only for the API calls received and the data transferred.

How does AWS API Gateway work?

API Gateway Benefits

• Low-Cost and Efficient
• Performance at Any Scale
• Easily Monitor API Activity
• Streamline API Development
• Secure and Flexible
• Flexible Security Controls
• Create RESTful Endpoints
• Run Your APIs Without Servers

 Elastic Transcoder

Media transcoding in the cloud.

Businesses and developers could transcode or convert media files from their source format into versions that will playback on devices such as PCs, tablets, and smartphones.

It is designed to be user-friendly, economical, and highly scalable.
