To promote cloud computing and overcome privacy and security concerns, it is proposed to integrate blockchain into the cloud.
Blockchain technology and cloud computing can be combined. When the cloud is integrated with blockchain, different clouds are treated as nodes. And inter-node communication is possible in blockchain. All nodes on the same network exchange data with each other, so that each node contains a copy of the transactions.
Blockchain helps overcome some of the data security problems associated with clouds because of its properties.
Thanks to blockchain’s anonymity, personal data cannot be leaked.
Thanks to immutability, blockchain protects data from tampering.
By duplicating data, the resilience of a blockchain-enabled system can be increased.
Consider applying blockchain integration to cloud computing.
Fault-tolerant systems with data encryption
Multiple clouds can be used, each of which we don’t trust, but at any given time we trust most of them. Let’s take each cloud’s computing power and take the anti-tampering properties of the blockchain. Blockchain has redundancy properties, and different clouds (which are blockchain nodes) store the same data, which will also make the data available at all times.
Consider a scenario where blockchain is used to schedule user tasks in the cloud. To ensure confidentiality, timeliness and constant data integrity, the management system that takes a user-entered task first encrypts it and then creates an encrypted block and calculates the block hash code, then writes it to the blockchain database. Each node in the network contains a copy of each transaction, which ensures high data availability (minimizing downtime). Blockchain also helps the network withstand potential disruptions and attacks.
Cloud computing in such a system produces the work of blockchain nodes, for example, each cloud can be represented by a supernode that performs mining and validation operations physically on multiple computers, which will allow the system to scale to any size by means of a cloud provider, who can sell the work of the described system as a service.
Cloud computing has been around for years. But people are still trying to overcome some of the problems of cloud computing, such as data security, data management, compatibility, etc. But the cloud also has advantages, such as scalability.
Blockchain technology is an emerging technology, well known for its security when applied to cryptocurrencies. But it also has disadvantages, such as scalability.
By integrating blockchain into cloud computing, there are many advantages: data trust, security, scalability. There are no specific technologies that implement such integration yet, but they are not far off!
