• Real-Time Workloads: These workloads process data and respond immediately. Examples: live chat applications, financial trading platforms, or online games.

3. Based on Deployment Model:

• Infrastructure as a Service (IaaS): Gives users the highest level of control but also the most responsibility. Users manage everything from the operating system, networking, and storage up to the application layer.

• Platform as a Service (PaaS): The cloud provider takes care of the lower-level infrastructure, allowing users to focus on developing and deploying their applications.

• Software as a Service (SaaS): Applications are offered as fully managed services, accessed over the Internet. Users don’t need to worry about any underlying infrastructure or software maintenance.

4. Based on Cloud Native Technology:

• Virtual Machines (VMs): The traditional building block of cloud infrastructure; each application is deployed within a self-contained virtual machine, providing a high level of isolation and control.

• Containers: Offer lightweight and portable packaging for applications, enabling faster deployment and greater scalability. They are ideal for microservices-based architectures where applications are broken down into smaller components.

• Serverless Computing: Focus shifts to code only, with the cloud provider managing all underlying infrastructure. Best suited for unpredictable workloads with short, event-driven tasks like image processing or responding to API requests.

Tasks That Are Suitable for the Cloud Workloads

With the diverse range of cloud workloads laid out, let’s delve into the types of tasks that are particularly well-suited for this powerful technology:

1. Scalable Applications: Cloud workloads excel at accommodating fluctuating demands. Applications with unpredictable or bursty traffic patterns, like e-commerce platforms during sales or social media apps during peak hours, benefit from the cloud’s ability to scale resources up or down seamlessly.

2. Data-Intensive Tasks: Cloud environments offer vast, scalable storage solutions, making them ideal for handling large datasets and complex data processing needs. Tasks like scientific research, big data analytics, and machine learning training can efficiently leverage cloud resources.

3. Collaborative Workloads: Cloud-based applications enable seamless collaboration and information sharing in real-time, regardless of geographical location. Teams can work on documents, projects, and data simultaneously, fostering improved communication and productivity.

4. Content Delivery Networks (CDNs): Cloud workloads are instrumental in powering CDNs, geographically distributed networks of servers that deliver content like web pages, videos, and images to users with minimal latency. This, in turn, ensures a fast and smooth user experience for geographically dispersed audiences.

5. Continuous Integration and Continuous Delivery (CI/CD): Cloud platforms streamline the CI/CD pipeline, automating the process of building, testing, and deploying applications. Hence users can achieve faster development cycles, improved code quality, and quicker delivery of new features.

6.
