What will you get out of this course?

To create, secure, and operate APIs without managing servers, use AWS API Gateway and Lambda Host SPAs.

User authentication should be included in serverless apps.

Run applications in the cloud whenever you want.

What is AWS?

AWS is an Amazon company that offers people, businesses, and governments expect to be paid on-demand cloud computing platforms and APIs. Through AWS server farms, these cloud computing web services provide dispersed computing processing power and software tools. Amazon Elastic Compute Cloud is one of these services, giving users access to the online computer cluster that is always up and available. The majority of a real computer's functionality is replicated by the virtual machines offered by AWS, which additionally come with pre-installed application packages like web servers, databases, and others.

Managing relationships with customers. One can choose from a variety of operating systems, networking, hard disk/SSD storage, hardware central processing units (CPUs), and graphics processing units (GPUs) for processing, among other things.

What is API?

Application programming interfaces allow for interaction among two or more computer programs (API). It is a form of software interface that gives other software programs a service. An industry standard or document known as an API specification describes how to build or use this kind of connection or interface. If a computer complies with this standard, it is deemed to provide or expose an API. Both the specification and the execution are referred to as "APIs"s.

APIs, also known as application programming interfaces, are software stepping stones that allow for the interaction of two applications. Every moment you use a mobile phone app, such as Facebook, send an sms alert, or check the weather, you utilize an API.

What is AWS Serverless API?

The incredibly simple and user-friendly AWS API Gateway tool enables developers to create and maintain HTTP endpoints and link them to particular AWS resources.

Furthermore, it provides advanced capabilities that enable application teams to configure distinctive domains, authorization procedures, caching, and other characteristics for the APIs. API Gateway is the primary element of serverless APIs because it is responsible for creating the connection between a particular API and the function responsible for responding to requests to that API.

To demonstrate the main concepts of a serverless API, We'll build a tiny virtual whiteboard application. There will be just two primary endpoints: POST for putting messages on a whiteboard and GET for collecting the three most recent messages. Using the AWS Serverless Application Model and Amazon DynamoDB as the serverless database component, we will create our architecture.

What advantages does the AWS Serverless API offer?

A reduction in complexity

They can help reduce the complexity of the system as a whole by directing queries to a single location. If your back services are varied, this is extremely helpful. To do this, you can streamline your application's user interface, combine several requests into one, or rewrite requests in a way that your backend operations can execute them more quickly. As a result, your program may be easier to use for both programmers and end users.

Security

By verifying and validating queries, API gateways can add an extra layer of security before they reach your backend services. By standing in front of your application, they can act as a firewall between it and the external world by filtering traffic and only permitting requests that comply with your security standards to pass through.

Increased effectiveness

By storing commonly used and requested data, API gateways can distribute demand over multiple servers. By not having to collect it each time a query comes in, your service would save time and effort.

Who may take this course?

Who prefers to focus on the crucial business strategy instead of the infrastructure needed to host an API and/or SPA?

Anyone who wants to use modern techniques to create highly affordable and flexible web applications

Anyone who frequently uses APIs and/or SPAs and wants to understand how to create flexible, cheap web apps should take this course.

Any developer who appreciates the "Dev" element of "DevOps" but would be happy to see the "Ops" element simplified.
