Yau is a Professor at Arizona State University’s School of Computing, Informatics, and Decision Systems Engineering, and has published over 200 papers in the areas of distributed systems, cloud computing, and performance evaluation. Lau is a Professor at Hong Kong Polytechnic University and his research interests include cloud and mobile computing, computer networks, and distributed systems. Together, they bring a wealth of knowledge and expertise to the topic of cloud computing.
What is Cloud Computing?
In simple terms, cloud computing is the delivery of computing services over the internet. This includes storage, servers, networks, software, and analytics. Users can access these services on a pay-per-use or subscription basis, making it a flexible and cost-effective solution for businesses and individuals. The data and applications are stored and managed by a network of remote servers, allowing users to access them from any device with an internet connection.
Types of Cloud Computing
There are three main types of cloud computing: public, private, and hybrid. Public cloud computing is when services are offered over the internet by a third-party provider, while private cloud computing involves creating a dedicated cloud environment for a specific organization. Hybrid cloud computing combines aspects of both public and private clouds, allowing companies to store sensitive data on a private cloud while still accessing public cloud services.
Techniques and Applications
Yau and Lau cover a wide range of techniques and applications of cloud computing in their book. These include virtualization, which allows for the creation of virtual machines or containers for running applications on a single physical server. They also discuss techniques for ensuring security and reliability in cloud computing, such as encryption and fault tolerance.
The authors also dive into the various applications of cloud computing, including software as a service (SaaS), infrastructure as a service (IaaS), and platform as a service (PaaS). SaaS involves the delivery of software applications over the internet, IaaS provides access to computing resources such as servers and storage, and PaaS offers a platform for developers to build and deploy applications.
Benefits and Challenges
One of the main benefits of cloud computing is its scalability, allowing businesses to easily scale their resources as needed without the cost and maintenance of physical infrastructure. It also provides increased efficiency, as multiple users can access resources and work collaboratively in real-time. However, with the benefits come challenges, such as data security and privacy concerns, vendor lock-in, and potential downtime and outages.
Conclusion
In conclusion, Cloud Computing Techniques and Applications by S. S. Yau and H. C. Lau offers a comprehensive look at the various techniques and applications of cloud computing. The book is a great resource for those looking to gain a deeper understanding of this rapidly evolving technology. As more businesses and individuals turn to the cloud for their computing needs, it is essential to stay informed and up-to-date on the latest techniques and applications.
