The Technical Value of Cloud Computing

Cloud computing has evolved as a formidable technological intervention in recent times, which changed the conventional perceptions of computing. It has completely transformed the ways in which companies obtained, operated, and managed their computing resources. Most important of all, cloud computing enables a highly flexible and agile computing environment for coping with the rapidly changing needs of the business and enterprise sector. 

The flexibility of cloud computing is one of the foremost traits for which it could promote the adoption of new technologies like blockchain. Cloud computing can definitely play a crucial role in addressing the concerns of complexity in implementation of blockchain solutions. This is where the “as a Service” model comes into the picture.

“as a Service” Model

The “as a Service” annotation basically points out the approach followed for delivering specific services. As of now, the most common and earliest models continue to enjoy formidable popularity. They are Infrastructure as a Service or IaaS, Platform as a Service or PaaS, and Software as a Service or SaaS. Blockchain solutions can also be delivered through these models, and enterprises need to find a suitable alternative for their requirements. 

Therefore, the Blockchain IaaS vs PaaS vs SaaS comparison is definitely necessary to find out the best alternative among them. Now, it is important to obtain a clear impression of Blockchain IaaS as well as PaaS and SaaS alongside their advantages and setbacks. The information could help in setting a perfect foundation for comparing them on the basis of different factors. 

Blockchain as IaaS 

Blockchain delivered in the Infrastructure as a Service or IaaS model features direct similarity with the cloud service delivery model. IaaS basically implies delivery of services with access to a completely provisioned and on-demand computing infrastructure. The infrastructure could be subject to flexible management over the internet. 

In the case of blockchain IaaS model, companies could gain the advantage of on-premises computing resources. However, they don’t have to worry about deployment, maintenance, and operations of in-house infrastructures. IaaS also delivers promising functionalities for easier resource management and scalability. 

Consumers have to rent the resources like storage, hardware components, and computation resources for using them according to their needs. So, enterprises could easily pay for more resources when they need more performance. At the same time, organizations could also scale down to save costs when operations need limited resources. 

The users exert complete control over their infrastructure through a dashboard or an API. With the higher degree of control in blockchain IaaS, users would have to take care of managing certain aspects such as runtime environments, operating systems, data, applications, and middleware.               

Enterprises can leverage the functionalities of blockchain IaaS with the services of a cloud provider. Cloud services would reduce the complexity of purchasing, installing, operating, and maintaining the computing resources required for blockchain-based applications. 

So, what are the promising advantages of choosing the IaaS model for blockchain solutions?

  • Blockchain IaaS ensures limited investment in expensive equipment. Furthermore, on-demand resource usage also improves cost-effectiveness of the IaaS model.   
  • IaaS in blockchain could offer a better modular approach and flexibility, thereby enabling the easier development of new ideas and solutions. 
  • The readily available resources offer adequate prospects for improving efficiency through the IaaS model.
  • Cloud provider takes care of setup and maintenance of hardware components for blockchain infrastructure, thereby empowering opportunities of productivity for developers. 
  • The prolific improvements in scalability and flexibility with IaaS also contribute to faster development lifecycles. 
  • Enterprises could also discover the benefit of scalability according to their performance requirements with the blockchain IaaS model.

While there are many value propositions associated with the IaaS service delivery approach for blockchain, it also features certain limitations. Here is an outline of the setbacks you can find with blockchain as IaaS. 

  • Lack of migration policies and tools could lead to vendor lock-in.
  • Security threats are prominent in data communication between virtual machines and host infrastructure.
  • Users need improved know-how of blockchain development alongside taking over responsibility for security and maintenance of infrastructure.
  • Legacy systems could not leverage the full potential of blockchain IaaS solutions without radical modifications.

Blockchain as PaaS

Platform as a Service model is also a prominent mention among the service delivery models in cloud computing. The discussion on Blockchain IaaS vs PaaS vs SaaS comparison has been turning the limelight towards PaaS profoundly. It focuses on helping developers with better functionalities for easily creating, running, and managing their own applications. 

Blockchain PaaS has been gaining attention from notable players in the domain of technology for various reasons. It can help enterprises expand their business functionalities alongside refining their strategies. All you have to do is rely on the Blockchain PaaS service provider for management and maintenance of the blockchain infrastructure. 

Interestingly, many leading cloud service providers have anticipated the potential of blockchain rightly in introducing their BPaaS services. The most primary advantage of the PaaS model for blockchain is the better and easier adoption of blockchain. PaaS completely takes away the need for integration and installation procedures. 

As a matter of fact, many experts have stated that Blockchain PaaS is suitable for developers seeking opportunities for developing blockchain-based applications. The model does not impose any responsibilities for management of operating systems, infrastructure, software updates, or storage. Most important of all, PaaS for blockchain is also appealing for enterprises that want to dive into the domain of blockchain. 

The Blockchain PaaS model presents the following advantages.

  • Better time efficiency with faster creation, testing, and deployment of new blockchain solutions.
  • Improved cost-efficiency with major maintenance tasks and upgrades by service providers.
