Cloud computing and Blockchain
In the various forms and features of IT industry, Cloud computing has been very actively brought into play because it has successfully emerged as an indispensable piece of engineering science, to provide infrastructure and data service requirements with negligible endeavours, very high level of flexibility and affordability. There has been a rapid growth in Cloud computing adaptation, but the information security concerns have not been addressed properly. These problems need to be resolved soon, because it seems that they are obstructing the growth of Cloud computing. Meanwhile, to offer security mainly in the areas of authenticity, confidentiality and integrity, blockchain has appeared on the horizon as the principal technology. This technology, wherever employed, makes everything decentralized. The decentralized servers receive all the information by the distributed ledger technology, which gets these data and keeps track of them too. This way, it works only with code, and therefore, it cannot be tampered with.
Advantages of the integration
1.The significant challenge of computing which is privacy and security, is effectively taken care of when blockchain technology is integrated with cloud computing. Most of the users feel that data loss and leakage are the biggest threats of cloud computing. Blockchain offers security and protection of databases by way of encryption of data.
2. Many users also feel that transparency and visibility are hindrances to cloud security too. The distributed and decentralized system of blockchain enables transparency. Interfering with data is prevented by public blockchain which makes every activity visible. It is almost impossible to fiddle with data stored on the blockchain.
3. Even if data from a computer on a blockchain network is tampered with or erased, data stored in other gadgets on the network remain unaffected. So there is absolute reliability, genuineness and no loss of data.
4. Since third-party providers are involved in Cloud computing, a crash or downfall of these external vendors can bring about a humongous loss of data for the concerned organizations. However, blockchains are not involved with third-party service providers and work with codes. So, deploying of blockchain technology is a much safer option.
5. Ownership of data is facilitated by blockchain which helps, to say the least. The data stays permanently on blockchain. It offers traceability too, as a result, it’s easy to know, how, when and where the data is being used. It identifies the user as well. So, this is actually full audit and authentication benefit which the evidence and history of all transactions and alterations made along the way provide.
The blockchain system can be highly advantageous and favourable in spheres of performance enhancement and functionality due to its special characteristics. Improvement in security of Cloud computing is another aspect which it can effectively take care of. Since Cloud computing mostly deals with large amount of data and works on a centralized architecture, there is always a risk of forgery and deception. Likelihood of the central server being hacked is immense which will make the whole system impaired and lopsided without any backup of data. Recovery of data will be impossible. Deploying blockchain in Cloud computing will prevent these problems to arise in the first place.
