Cloud Data Management: Techniques, Challenges, and Best Practices

2 March 2025 Afzal Badshah, PhD Comments 0 Comment

Cloud Data Management is a critical aspect that ensures the efficient storage, retrieval, processing, and security of data across distributed cloud environments. With the increasing volume of digital data, traditional storage systems are no longer sufficient. Cloud computing provides scalable and distributed solutions for managing data efficiently, integrating technologies such as Hadoop Distributed File System (HDFS), Google File System (GFS), and Microsoft Dryad/SCOPE. The detailed tutorial can be accessed here. 1. Key Concepts of Cloud Data Management Cloud data management…

Hypervisors in Cloud Computing

13 February 2025 Afzal Badshah, PhD Comments 0 Comment

A hypervisor, also known as a virtual machine monitor (VMM), is a critical software layer in virtualization technology. It allows multiple virtual machines (VMs) to run on a single physical hardware system by managing and allocating resources such as CPU, memory, and storage to each VM. Hypervisors ensure that each VM operates independently, with isolated environments, while sharing the underlying hardware. Imagine you have a single powerful computer, and you want to run multiple operating systems like Windows, Linux, and…

Cloud Computing Architectures and Deployment Models

10 February 2025 Afzal Badshah, PhD Comments 0 Comment

Cloud Computing Architectures Cloud computing architecture refers to the various components and technologies that work together to deliver cloud-based services. These architectures define how computing resources are organized, managed, and delivered over the Internet. The main components of cloud architecture include front-end and back-end platforms, cloud-based delivery models, and networking infrastructure. You can visit the detailed course on cloud computing here. Visit the detailed tutorial here. Front-End Architecture This is the client-side interface that allows users to interact with cloud…

Virtualization in Cloud Computing

9 February 2025 Afzal Badshah, PhD Comments 0 Comment

Imagine you have a powerful personal computer at home. You are a single person, and you can utilize it up to a maximum of 30%, while the remaining 70% of the resources are wasted. How can you make full use of your computer’s potential? Introduction to Virtualization Virtualization is a technology that allows multiple virtual environments to run on a single physical hardware system. It works by abstracting hardware resources such as CPU, memory, and storage, creating virtual versions of…

Introduction to Cloud Computing

3 February 2025 Afzal Badshah, PhD Comments 2 Comments

Cloud computing is a technology paradigm that enables users to access computing resources—such as servers, storage, databases, networking, software, and more, over the internet instead of maintaining physical hardware. These resources are on-demand, scalable, and cost-effective, making cloud computing a vital component of modern IT infrastructure. The full tutorial can be accessed here. Key Characteristics of Cloud Computing On-Demand Self-Service Cloud computing allows users to provision computing resources automatically without requiring human intervention. This feature enables users to scale resources…

Cloud Computing Explained: Introduction, Technologies, Applications & Challenges

24 June 2024 Afzal Badshah, PhD Comments 109 Comments

We encounter cloud computing every day. For instance, if you use an Android phone, your photos and videos are likely backed up to a cloud service like Google Drive. Similarly, if you use Microsoft OneDrive, your data is copied to the cloud. Cloud computing also supports our email services, social media, and messaging apps like WhatsApp. But what exactly is cloud computing? Cloud computing can be defined as a utility service. Just like electricity, gas, or water, cloud computing provides…

Cloud Storage Future & Its Opportunities

9 November 2022 Afzal Badshah, PhD Comments 147 Comments

The future of the Cloud Storagee is no less than a dream. AI-enabled objects (e.g, self-driving vehicle), the web of IoT devices, and 5G connectivity (i.e, mobile communication technology) is changing the way of living. The recent advances in smart technology generate massive data traffic. The 51 billion devices forecast is a big number: even seven times greater than the whole world population. These devices will increase the annual size of the global data sphere up to 175 ZB. Another report…

Issues and challenges in Cloud Storage: What you Need to Know

28 September 2022 Afzal Badshah, PhD Comments 2 Comments

Cloud Storage provides storage services as a vitalized environment where a user has no control over the data. In such a situation, a user may ask questions like “where exactly is my data located?”, “what happens if I delete my data?” and “is the deleted data really deleted?”. From home appliances to industrial enterprises, the Information and Communication Technology (ICT) industry is revolutionizing the world. We are witnessing the emergence of new technologies (e.g, Cloud computing, Fog computing, Internet of…

What is Regional Computing? How Can it Address the Social Big Data Effects?

23 September 2022 Afzal Badshah, PhD Comments 1 Comment

Regional Computing is similar to edge or fog computing, placed near the users’ end to process and store the data at the regional level, rather than migrating it to the cloud. Regional computing drastically minimizes turnaround time, transfer time and costs. Social media cloud servers are located at a long distance, resulting in delays and large workload, leading to low performance and high costs. Regional computing can be used to solve this problem, which already has about 104 billion global investments in the form of edge and fog computing (Badshah et al., 2020, Badshah et al., 2019, Social Networks Statistics, 2021).
