cloud-computing vs blockchain

There is a lot of buzz around some of the latest new trending technologies that have captured people’s attention. Some of these are still being developed, while others may be already here but not yet used by mainstream users. 

Here we’ll list down three of the emerging technologies which we believe might be the ones to go mainstream before everything else. You might want to look into them. 

Top Three Latest trending technologies

Blockchain technology 


Blockchain has been making waves for quite some time now as many businesses explore ways to use this distributed ledger technology to improve their operations. It was first introduced back in 2009 by Satoshi Nakamoto, who wrote up the Bitcoin whitepaper, which has now become the world’s most popular cryptocurrency. 


Blockchain is essentially an open-source, decentralized database where data can’t be changed once recorded on it without going through every single node on the network. This means there’s no room for fraud, tampering, or errors when transactions take place, thanks to its decentralized nature. 


And because everyone has access to these records, they can see everything that happens within the system.


In addition to financial services, governments worldwide also consider using blockchain to record voting results or even create digital IDs. With so much potential in-store, blockchain will likely keep evolving and find applications outside finance soon.


How Does Blockchain Truly Work?

To fully grasp the concept behind blockchain, you should know what a block actually is. A block consists of lots of lines of codes containing relevant data related to that specific transaction.


Once set, blocks cannot be modified unless someone else confirms the change. Think of it as a permanent logbook recording activity taking place on the chain. Because anyone connected to the network can read it, both sides ensure accuracy and transparency during payment settlement. 


Moreover, blockchain prevents double-spending, thus preventing coins from getting hoarded by miners. All these factors result in faster confirmation times and reduced fees for participants in each exchange. The only way to make a double-spending attack on a blockchain is with a 51% attack (malicious users collude with each other to manipulate the transaction confirmation).

In an established blockchain network such as Bitcoin or Ethereum, this is very hard to do. If you want to know why, read more about blockchain in my What Is A Blockchain guide.

Cloud Computing

After blockchain, cloud computing is another interesting trend in the IT sector. Cloud computing refers to storing your files online in the cloud to make them accessible from anywhere. You don’t need to download them onto your computer whenever you wish to view them. 


Instead, it allows users to connect to remote servers and get their content instantly via an internet connection. While traditional computers require hard drives (or SSD) locally installed into them, cloud storage uses multiple interconnected devices across different locations, hence the name “cloud” referring to clouds surrounding us everywhere.


With so much information stored online nowadays, security has become increasingly important. That’s why cloud providers usually implement advanced security measures like intrusion detection systems, firewalls, and other security measures to ensure the user data is guarded properly. 


As it turns out, cloud computing is becoming one of the fastest-growing sectors globally. Last year alone, we saw $243 billion spent on public cloud infrastructure compared to only $92 billion on private clouds.

The Use Cases Of Blockchain As Compared To Cloud Computing:


Above, we mention both blockchain and cloud computing to be the top trending tech. But what are the actual differences between their use cases?


Since its inception, blockchain technology has not really taken off despite the blowup of cryptocurrency prices last year. That being said, nowadays, companies are exploring various ways to leverage blockchain to improve their business processes. 


There are several industries leveraging this technology to streamline their existing practices. One notable example is the healthcare industry, where patients maintain complete ownership of their medical history and personal details. Thanks to blockchain, doctors can easily review patient histories and conduct follow-ups conveniently. Another good example would be the supply chain industry which allows food producers to track products throughout production, delivery, packaging, distribution, and sales. 


Lastly, retail stores can also utilize this mechanism to monitor inventory levels and order fulfillment simultaneously.


For example, IBM collaborated with DNV GL, to develop a platform powered by smart contracts and blockchain. The service aims to provide reliable transaction processing between parties involved in shipping activities. By doing so, it cuts costs associated with managing reconciliation procedures and ensures speedier payments. 


Blockchain adoption outside the crypto speculation space is not as fast as cloud computing due to how complicated the process is (since it requires consensus and more decentralization)

How About The Use Cases Of Cloud Computing?

On the contrary, cloud computing is relatively straightforward and easy to understand. Basically, it involves renting space in a server owned by a provider, giving you full control of those resources. So long as you pay rent for the usage, you will continue accessing your files regardless of whether you own the device you’re currently working on. 


If you’re looking for extra protection and security, you could choose a reputable hosting firm offering SSL certificates. Aside from securing your data, cloud computing also offers flexibility and scalability.


For instance, let’s say you’re planning to host a website for your small business. Since you’ve got limited funds, you’d probably opt for shared web hosting, which provides cheap monthly plans shared among thousands of websites hosted on the same physical machine. On the other hand, dedicated servers offer exclusive access to hardware components, including CPU, RAM, GPU, etc., allowing you to scale up anytime you wish.


Most internet businesses nowadays rent spaces via cloud computing.


Virtual Reality (VR)

Last but not least, Virtual Reality (more explanation on Wikipedia) has become a hot topic over the past few years after Oculus Rift was launched in 2016. VR headsets enable users to immerse themselves in 3D worlds created on high-end PCs running specialized software.


While VR contents are already available for mobile hardware, most developers still prefer developing content for VR headset on the PC due to better hardware specification. Still, the mobile VR gaming experience isn’t bad either, just that the user experience won’t be as good.


How Does Virtual Reality Truly Work?

While VR gaming is great and fun, it doesn’t necessarily mean that playing VR games will always require owning expensive equipment. Well, if you fancy yourself as a casual VR enthusiast, try building your own headset using cardboard instead, just like how Google instructs us to do so. 


Virtual reality headsets usually consist of two parts: display unit and head tracking module. Display units come in various forms, including OLED screens, LCD monitors, micro displays, and others. Meanwhile, the latter includes external sensors equipped with accelerometers and gyroscopes along with electronic circuits responsible for measuring movement. 


Both parts communicate wirelessly with corresponding processors inside the game device. Head tracking modules determine the orientation of the viewer based on tracked movements. To play VR games, you must pair your smartphone or PC to the VR goggles. After that, you simply launch the app and start enjoying the immersive VR content.


As mentioned earlier, Google Cardboard is a common type of VR headset available in the market nowadays. It typically contains a simple display made of plastic sheets covered with mirrored material to reflect light emitted from phones’ LED panels. If you plan to experiment with VR and want zero compromises, you can try Oculus, a VR headset by Facebook for PC equipment.

Other top trending technologies


Aside from blockchain, cloud computing, and virtual reality, there are plenty of other technological trends worth mentioning. They are artificial intelligence (AI), Internet of Things (IoT), Big Data analytics, nanotechnology, green energy projects, and 5G networks. The list goes on and on. We won’t discuss all of them right here but we will write more about them in the future.


Moreover, you shouldn’t forget about augmented reality (AR), and mixed reality (MR), which you can say are similar technologies to VR. These technologies are expected to bring revolutionary changes in our lives in terms of navigation, interaction, education, training, entertainment, advertising, marketing, social networking, etc. For one, I can’t wait for these technologies to take off
