The Framework of Serverless Architecture

Serverless Architecture consists of the following components

1.   Application or Website: This the User Interface rendered in Java, Python, .Net Core etc., Which allows the users to interact with a simple static web server.

2. Web Server: A simple yet robust web server which can serve all the static HTML, CSS and js files of the website or app.

3. Compute Service: A computer service runs the code in response to an HTTP request. In other words, this function reads and writes the databases to provide JSON responses. This is the key enabler in serverless architecture.

4. Security Token: This will generate temporary API and Secret keys for the website users. These credentials are used to invoke the compute service to communicate with the server.

5. Authentication: This component helps in creating user sign-in and sign-up functions for the websites and applications. It also has options to authenticate users through social networking providers such as Facebook, Twitter etc.,

6. Virtual Data Centre: This is the pool of cloud infrastructure that takes care of storage and networking. It consists of physical data storage hardware and servers.

Infrastructure as Service (IaaS): In this type of service the users will have direct access to the cloud servers and associated resources via a dashboard. The website developer can rent virtual data center and save on the cost associated with the purchase and maintaining computer servers, cloud networks, and storage. This is the most flexible cloud computing model and provides the users true control over the infrastructure and flexibility in scaling.

The Framework


Platform as Service (PaaS): In this type of cloud computing service, the environment to run the code and the server maintenance is taken care by a third-party service provider. All the web developers need to do is write the code on the platform and it will run and execute the backend processes.

The Framework 

Function as Service (Faas): This is the most simplified form of cloud services. The developer only needs to provide the code for the application to run; all the events from there are taken care by the service provider. The FaaS service provider will offer the application framework managed by the cloud service provider.
