You've probably heard "blockchain" as one of many next-generation IT initiatives, logically it has its advantages and disadvantages, especially in relation to Datacenters. However, blockchain's growing influence can provide organizations with a competitive advantage when used properly.
Currently, blockchain technology is one of the biggest trends in the industry. According to surveys in recent months by top consulting firms, they said they believe blockchain technology is widely scalable and has achieved widespread adoption. In addition, nearly 80% also reported that their executive teams believe there is a compelling business case for using blockchain within their organization, and are discussing how to integrate it into their current strategies.
Blockchain is a state-of-the-art technology of highly secure and immutable records. Bad actors cannot break into the system or falsify the data stored in it. This distributed ledger technology records transactions and related data in a distributed manner, at the same time, which avoids a single point of failure and validates every piece of information it stores.
Compared against traditional databases, which store data in rows, columns, tables and files, a blockchain is decentralized and managed by computers in a peer-to-peer network. It stores data in chained blocks; during a transaction, each block of data is sent to each computer node on the network, where it is authorized and then securely attached to the blockchain. Once added, a block cannot be modified. Likewise the validation process ensures that the data is unique and legitimate, with timestamps to prove it. If someone tries to change a block, copy it or change its status, the network of computers that make up the blockchain is immediately alerted and no one can add new blocks to the chain until the problem is fixed. So you would have to try to make a change simultaneously in several locations.
Security is easily the biggest advantage of blockchain, followed by resiliency. Each block is continuously reconciled by a network of computers. If one node fails, it cannot bring down the whole system because all the other nodes have a copy of the ledger, in short a synchronization issue, not trivial.
There are several types of blockchain and a wide variety of uses in different sectors. The financial sector currently leads the way in blockchain adoption due to the way the technology can simplify the transaction process and blockchain as well.
In terms of "Datacenters" architecture, blockchain takes a different approach to data storage.
Blockchain uses decentralized architecture to manage and store data.
The blockchain network may consist of dozens, hundreds or thousands of computers spread around the world, in different locations. Then then, a blockchain breach succeeds, hackers would have to take down several computers in the network, and even then, the blockchain data storage is encrypted, which minimizes the security risk.
These strengths compete directly with traditional data center storage. Data centers house massive amounts of data in a single location. This centralization puts them at risk of natural disasters and local area outages. To add some redundancy and prevent data loss, organizations can copy data and store it in other locations; however, this process can be time-consuming and costly, and creates excess information that also needs protection.
Blockchain data storage can provide higher levels of security, reliability, redundancy, resiliency and transparency. Its distributed nature allows users to have a greater degree of control over where they store their data, which also affects accessibility and availability. So, accessibility and continuity can become a detractor from the decentralized approach. To retrieve a block of data, different nodes in the network must synchronize, validate and extract the block; this can take considerable time, depending on the location and load of the nodes. Traditional data centers can provide much faster speeds and greater impact in terms of data availability levels.
Blockchain security, while quite advanced, is not perfect either. As more users adopt the technology, bad actors will get better at finding and exploiting holes in blockchain. For now, however, it provides much better data security than in-house and cloud storage.
To summarize, cost is an important factor that determines whether organizations may choose to adopt blockchain. Although blockchain is becoming more popular every day, it is still not widespread among organizations, at least not at the same level as cloud storage, which is cheap and available in many forms today.
For data center teams pursuing a blockchain approach, start by reevaluating the data center infrastructure. Consider how to pivot resources, and start implementing and moving toward a decentralized architecture. Start thinking about how to set up a peer-to-peer network that can handle a blockchain workflow. The blockchain vogue also demands more reliable power, high-performance equipment that can process blocks of data quickly, and more intense cooling to keep that equipment from overheating during intense computations. The faster users can write and validate blocks, the better. So take these requirements into account and invest accordingly.
Traditional data center architecture must fundamentally transform to meet blockchain's demand for increased traffic and availability, which includes having staff with specialized blockchain skills.
In conclusion, it is imperative to consider blockchain as a highly secure, distributed data processing strategy with the advantages of being able to granulate processing blocks into small particles in the Metaverse.
