Blockchain IaaS Vs PaaS Vs SaaS – Key Differences



Cloud computing is the distribution of computing resources on-demand over the internet. Cloud computing allows users to access computational resources without having to maintain actual gear. Cloud computing resources can be delivered in a variety of ways. These delivery models provide different levels of abstraction for the user, and each has pros and cons based on the developer's goals. Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS) are three of the most prevalent delivery models (SaaS).

For modern businesses, blockchain technology is appealing. However, because the technology is new and unfamiliar to many people, there are risks in deployment due to technical change.

Furthermore, the restricted talent pool of blockchain professionals, combined with their high pricing, creates significant barriers to blockchain adoption. So, how might the Blockchain IaaS vs. PaaS vs. SaaS argument help businesses overcome their fears about blockchain adoption?

Surprisingly, the IaaS, PaaS, and SaaS models all pertain to the ways used to enable businesses to adopt blockchain technology. In discussions regarding cloud computing, you may have heard terms like IaaS, PaaS, and SaaS. These models are used by cloud service providers to deliver their services to businesses, and the same could be said for Blockchain.

Blockchain as a Service (IaaS)

The Infrastructure as a Service (IaaS) paradigm for delivering Blockchain is quite similar to the cloud service delivery model. It refers to the delivery of services with access to a fully provisioned and on-demand computer infrastructure. The Infrastructure might be managed more easily over the internet.

Companies could benefit from on-premises computing resources when using the blockchain IaaS paradigm. They do not, however, have to worry about in-house infrastructure deployment, maintenance, or operations. IaaS also offers potential features such as resource management and scalability.

Consumers must rent resources like storage, hardware components, and processing resources in order to use them as needed. As a result, businesses might easily pay for additional resources when they require increased performance.

Simultaneously, when operations require limited resources, corporations might scale down to save money.

Through a dashboard or an API, users have complete control over their Infrastructure. Users would have to manage various components of block chain IaaS, such as runtime environments, operating systems, data, applications, and middleware, due to the increased level of control.

Enterprises can combine Blockchain IaaS functionality with cloud services to create a blockchain IaaS solution. The complexity of obtaining, installing, operating, and maintaining the computing resources required for blockchain-based applications would be reduced by using cloud services.

Benefits of Iaas

So, what are the potential benefits of implementing blockchain solutions using the IaaS model?

  • Blockchain IaaS reduces the need for pricey equipment. Furthermore, on-demand resource utilization improves the IaaS model's cost-effectiveness.

  • IaaS in Blockchain could provide a more modular and flexible approach, making it easier to build new ideas and solutions.

  • The IaaS model has a lot of potential for increasing efficiency because of the easily available resources.

  • The cloud provider manages the installation and maintenance of physical components for blockchain infrastructure, allowing developers to focus on their work.

  • IaaS contributes to shorter development lifecycles by allowing for greater scalability and flexibility.

Drawbacks of IaaS

With the block chain IaaS concept, businesses might potentially benefit from scalability based on their performance requirements. While the IaaS service delivery strategy for Blockchain has numerous benefits, it also has certain drawbacks.

Here's a rundown of the drawbacks of using Blockchain as an IaaS.

  • Vendor lock-in could result from a lack of migration rules and tools.

  • Data transfer between virtual machines and host infrastructure is rife with security risks.

  • Users must gain a better understanding of blockchain development as well as assume responsibility for infrastructure security and upkeep. Without major changes, legacy systems would not be able to take advantage of the full potential of Blockchain IaaS solutions.

Blockchain as a PaaS (Platform as a Service)

Blockchain as a PaaS (Platform as a Service) paradigm is also a notable mention among cloud computing service delivery options. The comparison of Blockchain IaaS vs. PaaS vs. SaaS has shifted the spotlight to PaaS significantly. It focuses on providing greater functionalities for developers to simply create, execute, and manage their own apps.

For a variety of reasons, significant technology players have started paying attention to Blockchain PaaS. It can assist businesses in expanding their commercial capabilities while also fine-tuning their plans. All you have to do is entrust the management and maintenance of the blockchain infrastructure to the Blockchain PaaS service provider.

Surprisingly, many major cloud service companies correctly predicted the potential of Blockchain when launching their BPaaS offerings.

The most significant benefit of the PaaS model for Blockchain is that it facilitates and accelerates blockchain adoption. PaaS eliminates the requirement for integration and installation procedures entirely.

Many experts have indicated that Blockchain PaaS is appropriate for developers seeking opportunities to construct blockchain-based applications. There are no duties for managing operating systems, Infrastructure, software upgrades, or storage in the paradigm. Most importantly, PaaS for Blockchain is appealing to businesses interested in entering the blockchain space.

Advantages of PaaS

Some of the advantages of the Blockchain PaaS approach are as follows −

  • With the speedier invention, testing, and deployment of innovative blockchain solutions, you may save time.

  • Major maintenance efforts and enhancements by service providers have improved cost-efficiency.

  • Developers without technical knowledge could use the Blockchain Platform as a Service paradigm to access blockchain functionality.

  • In addition, Blockchain PaaS enables higher workload scalability.

  • The Platform as a Service strategy allows developers to concentrate on building and to upgrade the key functionalities of their applications.

Drawbacks of PaaS

However, Blockchain PaaS has some drawbacks, including the following −

  • Like the IaaS service delivery paradigm, the Blockchain Platform as a Service approach presents opportunities for vendor lock-in.

  • With Blockchain, the PaaS model also entails giving over control of your data to service providers, which raises security concerns.

  • Without considerable customization, legacy systems could not adequately align with the BPaaS concept.

  • The events and operations in the backend, i.e., on the side of the cloud service providers, are opaque to users.

Blockchain as a Software as a Service

The blockchain Software as a Service model would be the final element in the Blockchain IaaS vs. PaaS vs. SaaS comparison. The SaaS concept entails the delivery of on-demand Software to assist customers in connecting with and using applications via the internet. The Blockchain as a Service (BaaS) paradigm is also known as the Blockchain as a Service (BaaS) model.

It enables organizations working on the design, development, and deployment of blockchain applications to construct, administer, and maintain cloud-based infrastructures. The Blockchain SaaS model has proved critical in broadening the spectrum of blockchain technology's uses.

The SaaS paradigm for blockchain applications allows users to use cloud services for designing, hosting and operating blockchain-based apps.

Benefits of SaaS

The following are some of the significant benefits of the Blockchain SaaS model −

  • With the Blockchain Software as a Service approach, providers take care of essential hardware components, upgrades, middleware, storage, and servers, resulting in significant cost savings.

  • The Blockchain Software as a Service concept assures that the application is always available.

  • The second significant advantage of the Blockchain SaaS model is the ease with which service providers can effectively maintain it.

  • The Blockchain Software as a Service method, most importantly, allows for speedier deployment times.

Drawbacks of SaaS

The Blockchain SaaS model, like the IaaS and PaaS models, has its own set of drawbacks. They are, for example.

  • Vendor lock-in could be exacerbated by higher expenses and the difficulty of switching vendors.

  • The Blockchain as a Service concept does not allow for sufficient flexibility.

  • By providing service providers with control over their data, users must make a compromise in terms of openness and control.

  • For integration with on premise services and applications, BaaS providers provide limited functionality.

  • Security and performance are additional concerns with Blockchain SaaS. Because the service provider maintains and manages the service, the vendor is solely responsible for its performance and security.
