Software as a Service (SaaS) is a cloud delivery model where software applications are provided over the Internet. Users can access these applications through a web browser without needing to install or maintain them on their devices. SaaS makes it easier to use software on a subscription basis, with updates and maintenance handled by the provider.

Ques-27. What is PaaS, or platform as a service?

Platform-as-a-Service (PaaS) is a cloud computing model where users rent hardware and software over the internet. It provides tools for building, running, and managing applications without needing to install or maintain infrastructure. This allows developers to focus on coding rather than setup.

Ques-28. What is Infrastructure As A Service (IAAS) in cloud computing?

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. It offers basic infrastructure like servers, storage, and networking, allowing businesses to rent rather than own hardware. Users can scale resources on demand and only pay for what they use.

Ques-48. How does Rate-Limiting work?

Rate limiting controls the amount of traffic a server or API can handle by restricting the number of requests from a client within a given time frame. It helps prevent abuse, ensures fair use, and protects the system from being overwhelmed.

The mechanisms of Rate Limiting are as follows:

  • Fixed Window: The fixed window algorithm limits requests within set time intervals, such as 100 requests per minute.
  • Sliding Window: The sliding window algorithm dynamically resets the request count based on the timing of the last request, providing more granularity.
  • Token Bucket: In the token bucket algorithm, requests are allowed as long as tokens, representing capacity, are available and replenished at a fixed rate.
  • Leaky Bucket: The leaky bucket algorithm processes requests at a steady rate, similar to the token bucket, ensuring smoother traffic flow.

Ques-49. What is encapsulation in cloud computing?

In cloud computing, encapsulation refers to the abstraction and isolation of services, data, or resources into a secure and independent "container" that hides the implementation details from the user. Encapsulation allows users to interact with cloud services through a defined interface without needing to understand the underlying infrastructure, technologies, or processes.

  • Abstraction: Users access services without knowing the backend complexity.
  • Security: Encapsulation helps isolate resources, protecting them from unauthorized access.
  • Modularity: Components are packaged independently, improving scalability and maintenance.
  • Simplicity: Encapsulation simplifies cloud service usage, allowing focus on functionality rather than implementation.

Ques-50. How does Cloud Computing Use Resource Replication?

In cloud computing, resource replication involves creating multiple copies of data, applications, or services across various physical or virtual locations to ensure high availability, fault tolerance, and load balancing. This redundancy helps the cloud infrastructure deliver reliable performance and minimizes downtime in case of failure.

Here are the several ways to use resource replication:

  • Data Replication: Data replication involves storing copies of data across multiple data centers to prevent loss during failures.
  • Service Replication: Service replication runs multiple instances of an application to distribute load and improve responsiveness.
  • Geo-Replication: Geo-replication stores resources in different geographical locations for faster access and disaster recovery.
  • Load Balancing: Load balancing distributes user requests across resources to ensure smooth performance during high demand.
