cloud service models

You’ve already seen the PaaS, IaaS, and SaaS acronyms for the various cloud service models if you’ve been around cloud computing for a while. Cloud service models specify various levels of shared responsibility that a cloud provider and a cloud tenant are responsible for handle. Cloud computing provides different cloud models for deployment to its users as it works as a service provider.

Introduction to Cloud Service Models

Public cloud services are delivered to numerous people through the web. SaaS services provide companies with data storage and management features. Often, these are services for process automation, marketing, collaboration, and data organization. In this model, the applications are hosted by a cloud service provider and publicized to the customers over internet.

  • A private cloud is close related to virtualizationbut provides many of the benefits of public clouds, such as elastic scaling and resource sharing.
  • This infrastructure includes the physical servers, storage devices, processors, routers, switches, load balancers, and power distribution units that cloud providers maintain.
  • However, PAYG model is particularly beneficial for small and medium businesses who want to adopt cloud management services but are hesitant due to the high costs involved.
  • Today’s economic situation and environment require the ability to react quickly and respond to changing conditions and needs of consumers.
  • A private cloud is kept for confidential data and backups, which allows you to use less in-house storage space and use the small team for its maintenance.
  • For both mid-sized and small firms, this has shown to be of considerable assistance.

If you have no interest in the underlying infrastructure then PaaS takes agility to another level by enabling developers to focus more on business requirements and less on technical requirements. PaaS permits you to have admittance to computing power required to deliver new features or products to market quickly; the value of this far outweighs other benefits such as cost reduction. A further aspect of PaaS will give rise to business model alternatives with billing, monitoring, and metering capabilities. The full-service platform signifies that independent software vendors and IT divisions can enhance and deliver applications online utilizing third-party infrastructure services. With this deployment model, customers are generally looking to purchase functionality and pay for its use.

They can also develop customised AI applications by fine-tuning existing models, and run the models online using Alibaba Cloud or deploy them on other cloud platforms, the company added. Global cloud managed service market was valued at USD 86.32 billion in 2021, and it is expected to reach a value of USD 130.1 billion by 2028, at a CAGR of 10.2% over the forecast period (2022–2028). Microservices development is the process of creating software applications using code independent of one another and the platform they are built on. Once developed, each microservice has its distinct workflow and uses clear, standardized APIs for communication. To make it simple for developers to find the appropriate service and to comprehend the use of governance guidelines, these services are specified in the form of a catalog. IaaS is the most versatile cloud service because you have control over the configuration and management of your application’s running hardware.

IaaS provides computing architecture and infrastructure apart from that data storage, virtualization servers, and networking. Bare Metal as a Service – Some enterprises feel uneasy about migrating workloads to a virtualized cloud environment that’s shared with other customers. An alternative to IaaS and PaaS is Bare Metal as a Service, or BMaaS. It provides a way for enterprises to complement virtualized cloud services with a dedicated server environment with the same agility, scalability, and efficiency as the cloud. In particular, BMaaS is a great choice for enterprises that need to perform short-term, data-intensive processing—such as media encoding or render farms—without latency or overhead delays. PaaS is similar to IaaS, except that your cloud service provider also provides the operating system and databases.

PaaS (Platform-as-a-Service)

PaaS providers make available a development environment to application developers to develop, test, deliver and manage software applications. The vendors conventionally incorporate standards for development, channels for distribution, and payment mechanisms. It helps to remove the complexities of servers and provides a serverless architecture. You can focus on the business logic, and everything in the background is taken care of by service providers—all you have to worry about code development.

DaaS – Desktop as a service ensures a reliable, consistent experience for the remote use of programs, applications, and files anywhere, anytime. Plan out detailed data storage and security strategy to streamline the business process. You need to determine whether to deploy on a private or public cloud. Developers can easily build and deploy web-based software applications. PaaS suppliers handle all permitting for operating systems, development tools, and all that else remembered for their foundation.

Shared Responsibility Model:

HaaS differs from IaaS in the way that users have the bare hardware on which they can deploy their own infrastructure using most appropriate software. In IaaS, you buy complete resources rather than purchasing server, software, datacenter space or network equipment. At this week’s cloud event, known as the Apsara Conference, Alibaba also unveiled a range of upgraded database products and systems to help customers with cloud technologies. At the company’s cloud unit annual conference that opened Thursday, Alibaba said its ModelScope platform of AI models is available to global developers and researchers. The models cover various fields from computer vision to natural language processing.

Recently, cloud service providers have begun offering on-premises “private cloud” services. For example, IBM Cloud Private delivers an application platform for developing and managing on-premises, containerized applications. These new services help alleviate some of the management and capital expenses related to on-premises cloud architectures. The virtual machines and networking services are operated by the cloud provider, and the cloud tenant deploys their applications into the managed hosting environment. Infrastructure as a Service is basically hardware devices, such as network devices, visualized servers, storage, etc.

Cloud security follows what’s known as the shared responsibility model, meaning the duty of protecting cloud computing infrastructure is shared between the client and the provider. The provider must secure the physical infrastructure , the network infrastructure, the storage and computing systems, and their applications. Clients must secure the systems and infrastructure they use to access cloud services and the applications they develop and host on cloud infrastructure. From an architectural standpoint, the parts of a cloud model come together to form the cloud computing architecture.

Platform as a Service (PaaS)

On the other hand, SaaS delivers a complete cloud application that clients can begin using with little-to-no upfront work. But, clients can’t access the underlying infrastructure for things like scaling or performance optimization. The client’s access to and control over each aspect of cloud computing infrastructure varies depending on the service model of the cloud offering. Cloud services are obliged to use the latest and most efficient data security measures due to the large quantity of data handled through their cloud systems. Security of customer data is a prerequisite, as well as being a daily function. Hence, cloud services use security systems that utilize a distributed architecture that can absorb, filter, and deflect malicious requests that pose a threat to the system.

As a result, Cloud Computing might be considered the next step in the advancement of Virtualisation. Cloud computing infrastructure typically refers to the hardware and software that enables cloud computing. Hardware and software include storage devices, processors, networking equipment, operating systems, user interfaces, and applications.

Public Cloud

The different cloud deployment models examples include Software as a Service , Platform as a Service and Infrastructure as a Service . These business models can be classified and assessed by means of maturity models and the unique value chains that they offer for different industries. Cloud computing refers to offering computing services from servers in a network. Cloud computing is typically more secure than most private data centres. Providers of Cloud infrastructure also give tools and architectural alternatives for isolating workloads, encrypting data, and detecting possible threats. Parallely, public clouds operate on a shared responsibility paradigm, in which the user is responsible for the security of the data and applications stored on the Cloud.

It introduces enterprises to a virtualization environment where services facilitate cloud platforms and applications to connect and function. IaaS addresses compute services, in the form of a set of virtual machines with combined storage, processing capability, as well as other related services and network connectivity. This empowers multiple applications, maintained by different cloud consumers, to mutually share common physical resources, such as servers and storage.

It might turn out to be difficult to switch PaaS suppliers since the application is constructed utilising the seller’s tools and explicitly for their foundation. To switch sellers, designers may have to either revamp or vigorously change their application. Stages offered as a help ordinarily incorporate middleware, so designers don’t need to fabricate it themselves. Middleware is vital for running an application; however, end clients don’t communicate with it.


Frontend cloud computing infrastructure consists of applications, machines, and user interfaces. Therefore, organizations that use cloud services should be able to select deployment models that work best for their operations. Function as a Service is a concept of serverless computing where a service is hosted remotely to enable the deployment of functions in the cloud. FaaS uploads functional blocks of code which are activated by specific events. With FaaS, there is no need to manage cloud infrastructure or application runtimes as there is no consumption of IaaS resources. It means a cloud provider is giving you complete software like servers, databases, and application codes in the form of service.

Characteristics of SaaS

SaaS redistributes the task of managing software and its deployment to third-party services. American companies can be forced to access your data, according to the Patriot act. Besides that the new DSGVO regulations require every European company to host sensitive data in Europe instead of America. Apart from image problems and intellectual losses such a loss would entail, the European law can fine up to 4% of the comapany’s yearly revenue if some regulations are violated. Users can easily access the vast computing power available on IaaS Cloud platform.

Off-premises services, or public cloud services, are typically delivered by a cloud service provider and can be one of several service model types. For service providers, PAYG model allows them to offer cloud management services at a lower cost. They can also scale their services up or down as per the customer’s needs without any upfront investment. For customers, PAYG model provides them with the flexibility to use only what they need and pay only for what they use. However, PAYG model is particularly beneficial for small and medium businesses who want to adopt cloud management services but are hesitant due to the high costs involved. With PAYG, they can start small and scale up as their business grows.

You need to check if they provide support all the time before choosing your service provider. Therefore, you should make sure that the service provider’s data centers are compliant and secured. Not only did he drastically improve our backend architecture and nearly eliminate our tech-debt, he also taught us a great deal and pushed our company forward in the right direction. Justin is an expert architect who deeply understands how backend systems should be designed and is able to eloquently explain these concepts to members of the team who are less experienced. Many companies do not make use of their data, even though enormous new opportunities are hiding in plain sight. To process these huge amounts of data, a stable public cloud or Kubernetes is required, to make use of distributed processing and autoscaling.What We Do ?
