Sky computing is a new paradigm and a further development of the cloud computing model. It is seen as a model that combines the existing clouds of different service providers into a comprehensive, interoperable sky. The concept behind sky computing is to create a cloud of clouds that behaves in a similar way to the internet, which consists of a network of networks.
Description
Sky computing aims to achieve a complete abstraction of cloud resources from different providers so that applications and users can access these resources without having to worry about where the resources or services are located in the individual clouds. The key features of Sky Computing include:
Cloud of clouds: a unified, interoperable cloud made up of numerous individual clouds. Levels of abstraction: These ensure the interoperability of clouds. Distributed infrastructure: A comprehensive infrastructure for cloud services. Dynamic scalability: Resources can be scaled dynamically across multiple clouds. Universality: Applications can be run in any cloud.
Sky Computing significantly reduces the complexity of technology and cloud resources for developers and users.
History
The idea of sky computing stems from research conducted in the early 2010s by scientists in the fields of distributed systems and cloud computing. The idea of a unified, interoperable cloud forming a cloud of clouds was first introduced in a paper by R. Buyya et al in 2008[3][4].
The concept was further developed by Ion Stoica and Scott Shenker of UC Berkeley in 2021[5]. The concept of the intercloud broker is being continued by the SkyPilot project at UC Berkeley for science[6] and the start-up Perian from Germany for industry[7].
Challenges and future prospects
Although Sky Computing has the potential to revolutionise the cloud computing landscape, a number of challenges still stand in the way. These include technical challenges, data protection and security concerns and regulatory issues. Despite these challenges, many trends indicate that the concept of sky computing could play an important role in the future.
Sky computing is expected to lead to better scalability, performance and availability of cloud-based applications while creating new opportunities for innovation and business models.
