What are the Three Cloud Computing Service Delivery Models?

Visual services inspired the cloud computing service delivery models that currently dominate the market. The customers outsource their business to a service provider that hosts their software and databases on their cloud network for those unfamiliar with cloud computing systems. The service provider may charge a fee based on the service-level agreement.

The key benefits of such distribution models are their scalability and lower average maintenance costs. According to recent research, nearly 90% of businesses use cloud computing services in some form. SUSE, for example, provides integrated cloud computing solutions by deploying an open-source operating system that is highly scalable and high-performance.

The following are the three primary cloud computing service delivery models:

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)

Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) is a cloud storage service that lets businesses rent or lease servers depending on how much they use them. Clients use servers on public and private cloud networks instead of physical servers.

The key benefit of this setup for cloud computing service is that users can run any programme or operating system on the cloud server rather than purchasing and maintaining a physical server on their premises. In addition to lowering overall costs, IaaS lowers the costs of server maintenance and updates.

 Since the IaaS provider can handle the tedious tasks and do the heavy lifting for you, you may not need expert workers to manage several servers on-site constantly.

Another benefit of IaaS is the quick access to servers. IaaS gives business executives who have offices in various locations worldwide or communicate with foreign customers the opportunity to segregate their data.

IaaS automatically scales up and down depending on your demand, meaning that clients don’t need to worry about scaling up and fiddling with expansive hardware whenever they want to use additional memory or storage. Instead, everything is completed in real-time without wasting time and money formerly spent making modifications to the physical server.

Features and benefits

Features and benefits of IaaS in cloud computing service delivery models-

• Platform virtualization

 • Dynamic scaling

 • Reduced vendor lock-in

 • Automated operations

 • Virtual server space 

• GUI and API-based access 

• Load balancing capability

 • Pay-as-you-go model

Platform as a Service (PaaS)

Platform as a Service (PaaS) is a cloud networking configuration that enables a client to build, run, and manage software and applications on a service provider’s cloud platform. In this scenario, the service provider is responsible for providing a framework that includes, among other things, a database, storage space, operating systems, and middleware.

Depending on the client’s needs, the service provider allows the client to customize the platform resources according to their preferences. Software developers are increasingly turning to PaaS because it helps them to concentrate on the application and data. The service provider manages the platform, ensuring that the user has access to the tools required to improve their application while the developers fix system errors and prepare the public release software. The service provider adapts to the needs of the customer. A customer usually accesses the cloud-hosted hosted platform through a web browser. Many PaaS providers charge their customers on a pay-per-use basis, meaning they only pay for the services they use. Paying a flat monthly fee to use all of the platform’s products, on the other hand, is a viable choice.

Features and benefits

Features and benefits of PaaS in cloud computing service delivery models-

• Extensive pre-coded applications 

• Supports mobile workers 

• Rapid product creation

• Web-based user experience

• Multi-tenant architecture

• Third-party incorporation 

• Future evidence

Software as a service (SaaS)

Because of its popularity, SaaS is the most well-known of the three cloud computing service delivery models. In this model, the client’s software is hosted on the service provider’s cloud platform. The client can give multiple users access to the app by storing it on the cloud network. The main benefit of SaaS is that it allows a client to serve thousands of customers without having to maintain infrastructure on their premises. As developers release new features and functions, these professionals update the software for each client. Depending on the service level agreement, the client data can be stored on the cloud or at a local server.

Features and benefits

Features and benefits of SaaS in cloud computing service delivery models-

• Service that is available on demand

• Network that is self-contained

• Provisioning that is automated

• This is a multi-tenant model.

• Login with only one sign-on

• Billing based on a subscription

• Ideal for collaboration from afar

4. Unified Communications-as-a-Service (UCaaS)

Amid the current crisis, unified communications-as-a-service (UCaaS) is becoming more common. This service model provides users worldwide with communications continuity and remote collaboration services through the cloud network. Furthermore, this service model offers enhanced security and reliability, allowing remote workers to operate in a stable, virtualized cloud environment without interruption. As working from home becomes the standard and the digital workplace becomes the future of work, UCaaS services are being adopted by both SMEs and large companies to keep their teams linked while they work remotely. The UCaaS platform allows mobile workers to communicate and collaborate over the phone and video calls and share files, documents, and resources through cloud infrastructure.

Features and benefits

Features and benefits of UCaaS in cloud computing service delivery models-

  • Centralized management
  • Improved response time
  • Voice/VoIP technology
  • Audio/video conferencing
  • Supports BYOD
  • Rich data channel
  • Advanced security
  • Instant connectivity across devices

Conclusion

You can come across multiple SaaS platforms when surfing the web without realizing it. Emails, financial accounting tools, data services, images, customer relations management, and billing are all examples of SaaS websites hosted by service providers. While customers directly benefit from cloud computing services due to scalability, service providers hosting the software on the cloud can similarly earn profit. A symbiotic relationship between user and provider evolves because these companies can easily give consumers free trials, various billing options, and management software without the need to maintain a massive database and complex systems.
