Blockchain and Cloud Computing in Data Security and Efficiency

Overview

At present, data security is more important for individuals. As we all know, data generation is increasing for storage, and we require many data centers, which is impossible because it takes a large area of land and huge amounts of money and time to create it. This data center problem is rectified by using the cloud.

Cloud provides services over the internet, so you do not have to store data on a physical device and install software in your local system. You can directly use services over the internet.

The second problem that we discussed earlier is data security. Blockchain is a good solution because it stores data in a decentralized way. We will get to know more about this in this blog.

Cloud Computing

Cloud computing makes computer resources such as servers, storage, databases, and apps available always over the internet. Instead of buying and maintaining actual gear, customers can rent resources from cloud service providers on a pay-as-you-go basis. The adaptability of resources to demand enables this model to develop, evolve, and operate financially. AWS, Microsoft Azure, and Google Cloud Platform are among the most popular cloud services. By using cloud computing, individuals and businesses can focus on their core competencies instead of worrying about constantly updating and maintaining their infrastructure.

Blockchain

Blockchain is a decentralized, distributed, and digital ledger that allows secure information to be shared over the network. It records every transaction that is shared over the network, and these records are called blocks, which are linked through cryptography. Each block connects the previous block’s hash, timestamp, and the shared transaction data. The first and most famous cryptocurrency, bitcoin, is based on blockchain technology. The popularity of the blockchain is increasing because of its potential to provide high security to the data.

Use of Blockchain in cloud computing

In cloud computing, blockchain can be used to create a decentralized network of nodes that can be used to share data and process power. So, using that, we can minimize the need for a single centralized provider. Instead, they can store and share their data in a decentralized network of computers that does not completely depend on one single company, and they will not be in the control of one company.

This type of infrastructure can provide many advantages, including high security, improved scalability, and high availability. In addition, we can make a system that is not very feasible with traditional cloud-based architectures.

For example, blockchain is used to share data over the internet in a decentralized network of nodes, making a decentralized file storage system more secure than the current file storage system.

Blockchain technology can be used in the Cloud of Things. This is referring to the interconnection of the physical devices with the internet. We are using smartwatches, which are also connected to the internet using some technology, currently the Internet of Things. Still, as we know, in the present time, data generation is more, and storing and processing that data is somehow difficult using the Internet of Things, so this is one more way to use blockchain in the cloud.

How does this work?

If we have blockchain-based infrastructure, each node will be responsible for storing a copy of the blockchain in every node. When a new branch is added to the blockchain, all the nodes in the network will have to update the nodes with the new information. This allows a transparent and secure way of storing the data. We can also use this infrastructure to manage the data efficiently.

Comparison of Blockchain vs Cloud

Both technologies are offering different services. Cloud computing offers services like storing and accessing the data over the internet. On the other hand, blockchain is a distributed and decentralized database that stores data records over the internet. There are some points on which we can compare these two:

• Data access: In the cloud, users can access the data online, same goes for blockchain, but here, the data is encrypted using some functions.
• Cost: Cloud can be costly because businesses need to pay for using the services for storage and bandwidth but blockchain seems more cost-effective because no third-party cost is involved.
• Data visibility: The data in the cloud is mutable. Anyone can change the data, but the data in the blockchain is immutable, which means you have to add a new block to that existing block if you want to change something.
• Data security: In terms of data security, both cloud and blockchain have advantages. Data is stored in servers secured by firewalls in the cloud, and in blockchain, cryptographic techniques are used to secure the data.

Real-world applications and use cases

• Finance: Blockchain secures financial transactions by ensuring transparency and reducing the likelihood of fraud. Cloud-based financial systems use blockchain to speed up financial procedures and enhance data security.
• Healthcare: Using blockchain technology to secure cloud-based patient records and medical data, unchangeable records can be produced to ensure data integrity and privacy.
• Supply Chain Management: Blockchain technology in cloud computing reduces fraud and boosts supply chain transparency by tracking items and verifying product authenticity.
• Government and Voting Systems: Blockchain technology can secure digital voting systems, ensuring transparency and thwarting tampering, while cloud computing provides the infrastructure needed for scalability and accessibility.

Conclusion

The continued cooperation between these two technologies will probably spur additional advancements and uses as technology develops, influencing the direction of digital ecosystems.
