At the end you will find the answers as well with diagram if applicable.

Questions

  1. OAuth2 and good understanding of JWT Authentication flow
  2. Cloud Computing vs Cloud Native
  3. gRPC (gRPC Introduction - YouTube)

Cloud native refers to the principles and practices of building and running applications that are designed to fully leverage the benefits of cloud computing. Examples of cloud native technologies include:
  1. Containers (e.g. Docker) for packaging and deploying applications
  2. Kubernetes for container orchestration and management
  3. Serverless computing (e.g. AWS Lambda, Azure Functions) for running code without provisioning or managing servers
  4. Microservices architecture for building and deploying applications as a set of small, independent services
  5. Infrastructure as code (e.g. Terraform, CloudFormation) for provisioning and managing cloud resources using code
  6. Continuous integration and delivery (CI/CD) for automating the building, testing, and deployment of code changes
One example of a company that has adopted cloud native practices is Netflix. They use a combination of technologies like Amazon Web Services (AWS), Cassandra, and Netflix OSS to power their streaming platform, which serves millions of users.

Cloud computing is a model for delivering computing resources, such as storage, processing power, and software applications, over the internet. Examples of cloud computing services include:
  1. Infrastructure as a service (IaaS), such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), which provide virtualized computing resources such as virtual machines, storage, and networking.
  2. Platform as a service (PaaS), such as Heroku, AWS Elastic Beanstalk, and Azure App Service, which provide a platform for deploying and running applications without the need to manage underlying infrastructure.
  3. Software as a service (SaaS), such as Salesforce, Office 365, and Google Workspace, which provide access to software applications over the internet.
One example of a company that uses cloud computing is a retail company which uses AWS to run its e-commerce platform. The company uses a combination of services like Amazon Elastic Compute Cloud (EC2) for virtual servers, Amazon Simple Storage Service (S3) for storage, and Amazon Elastic Block Store (EBS) for databases. The company also uses AWS Elastic Beanstalk for deploying and managing its applications and Amazon CloudFront for content delivery. This allows the company to scale its computing resources up and down as needed, and only pay for what it uses.

Q 1) There are several other types of software applications:

  1. Platform as a Service (PaaS): PaaS provides a platform for customers to develop, run, and manage applications and services without the need for them to build and maintain the underlying infrastructure.
  2. Infrastructure as a Service (IaaS): IaaS allows customers to rent computational power, storage, and network resources on-demand, over the internet.
  3. On-Premises Software: On-premises software is installed and run on the customer's own servers and computers, rather than being hosted in the cloud.
  4. Desktop software: Software that is installed on a single computer or workstation and not available over a network or the internet.
  5. Mobile Application: Applications that are designed to run on mobile devices, such as smartphones and tablets.
  6. Server-based Software: Software that runs on a server and can be accessed by multiple users over a network.
  7. Open-source software: Software that is freely available to use, modify, and distribute to anyone.
It's important to note that many modern application are hybrid. For example, a saas application can make use of PaaS or IaaS infrastructure and thus have features that blur the lines of the traditional categories. As well, certain application can be a SaaS application on one hand, but also offer a desktop version to certain customers, it ultimately depends on the provider and the market they are catering to.

Q 2) IaaS vs PaaS vs Saas
