Distributed cloud is still developing in line with the progression of the technologies around the world that keep changing. So today we going to discuss about Distributed Cloud: Research Challenges. Distributed Cloud Computing comes with lot of threats. It rarely designed from the start, but build out of existing infrastructures. To prevent such threats, it need to keep up with the technologies while facing some obstacle through the process.
The first challenge that bothers analyzing suitable programming models, primitives and abstractions for distributed cloud computing. Nowadays, distributed cloud computing entrust on the virtual machines as a operation model but a programming model is still lacking. More improvement has been made over the years in the design of network programming languages giving higher standards of abstraction.
Next challenge is consistency and it connected to the programmability and also abstraction. Multiple round-trip times are needed to obtain stronger consistency. This can be achieve through trade-offs between the strength of a consistency model and performance.
Last but not least, the challenge that distributed cloud could face is privacy and security. Distributed cloud can boost privacy by keeping data local such as in the neighborhood. Still nowadays, we are still long way from applying this locality. Data may transmit far even to reach at a close cloud because we do not have the mechanisms for path control. Besides, multi-tenant clouds may really escalate the number of entities a user has to trust. Usually privacy comes at a performance expense that needs to be deliberate in design phase.
