What Are The Service Models Of Cloud – In today’s blog, we compare different models of cloud computing. Each model has its pros and cons; We have tried to cover the most important ones.
Let’s go into more detail and discuss the differences and pros and cons of different cloud computing models.
What Are The Service Models Of Cloud
Infrastructure as a service model is designed for companies that do not want to maintain their own data centers and manage infrastructure. An IaaS provider manages the hardware infrastructure (server, storage, network) and makes it available as a virtual resource on the Internet.
Design Your Cloud Operations
Cost Control – With IaaS, you pay for resources via a pay-as-you-go model – you only pay for the resources you use. There is no huge investment in infrastructure as the provider manages the infrastructure.
Scale easily – IaaS simplifies horizontal and vertical scaling – when you need more resources, you scale; When you don’t need it – you lower it.
Sophisticated security controls – Although major cloud platforms offer excellent security controls and adhere to many security standards, you may struggle to properly implement security policies.
As a platform-as-a-service model, developers use the platform to develop and deploy software. PaaS enables developers to quickly develop and deploy apps without worrying about infrastructure. The provider offers a range of email, image, video processing, database or other services that can be easily integrated into custom software.
The Basics Of Cloud Computing
Simple Management – PaaS providers maintain the infrastructure, so you have to manage everything. The Services can be accessed from any computer with an Internet connection and an Internet browser.
Speed of development – The platform provides many tools for common development problems like image and video processing, analytics and more that help you develop custom software faster.
Inability to meet predictable scaling needs – Compared to IaaS, PaaS platforms are harder to adjust to meet immediate and unpredictable spikes in demand.
In the software as a service model, the platform provider hosts the application and makes it available to users over the public Internet. With this model, users do not need to install any software on their computer or server – the application is available through any popular Internet browser. In the SaaS model, users don’t have to worry about software updates – the provider handles maintenance so the application is up-to-date.
Iaas Vs Paas Vs Saas
Instant access and ease of use – As soon as you create an account with the SaaS product, you’re ready to use it. The provider manages the software, so you have to worry about software updates.
Simple Scaling – As a user, you don’t have to worry about scaling. You add more users to the Platform or switch between different plans or subscriptions.
No control over infrastructure – As a user, you have no control over the provider’s cloud infrastructure. If the provider experiences any issues or incidents with the infrastructure, your application will also be affected.
Integration with internal applications – Most SaaS applications offer some form of API to integrate with other services. Your internal application may be outdated, making it difficult to integrate SaaS applications with your existing internal applications without any APIs.

The SaaS model is designed to deliver apps as-is; As a User, you subscribe to and use the Service immediately. You don’t have to deal with anything; The provider does everything in terms of application updates and hardware management.
The PaaS model is designed for developers; The platform offers unique services that accelerate development and application deployment.
The IaaS model is designed for companies that want full control of their infrastructure without any of the work associated with data center management. Infrastructure resources are presented as virtual resources on the Internet; With this model, you have simple scale with an efficient pay-as-you-go pricing model.

Cloud Computing Threats: Beyond Vulnerabilities
No matter where you are in your cloud journey, understanding basic concepts such as the different types of cloud service models is critical to your success in the cloud. These cloud computing service models provide different levels of control, flexibility and management capabilities. By learning more about the models, their benefits, and the different ways to deploy this infrastructure, you can choose the approach that best suits your business needs.
Different cloud computing service delivery models serve different needs, and determining which model is best for you is an important first step as you move to the cloud. The three main models are IaaS, PaaS, and SaaS.
IaaS is one of the most flexible cloud computing models. The infrastructure and its features are delivered in a fully remote environment, allowing customers direct access to servers, networks, storage and availability zones. Also, IaaS environments have automated deployments, which make your operations faster than manual deployments. Some examples of IaaS vendors include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. In such environments, the vendor is responsible for the infrastructure, but users still have full control over identity access management, data, applications, runtime, middleware, operating systems, and virtual networks.
What Is Iaas? How Is It Different From Saas And Paas?
Another cloud computing service delivery model is Platform as a Service (PaaS). PaaS is a subset of IaaS, except that customers are only responsible for identity access management, data, and applications. Instead of being responsible for hardware and operating systems like IaaS, PaaS helps you focus on implementing and managing your applications. Less need for resource storage, capacity planning, software maintenance and patching. Some examples of PaaS include Windows Azure, Google AppEngine, and AWS Elastic Beanstalk.
The most popular of the three models is SaaS, where deployment is outsourced to third-party services. Customer’s sole responsibilities are identity access management, data and software management. SaaS offers the complete package between IaaS and PaaS as infrastructure, middleware, and web-based applications can be accessed anytime, anywhere, regardless of platform. SaaS vendors include CRM services such as Salesforce and product software services such as Google Apps. A key benefit of SaaS is that it lowers software ownership costs and eliminates the need for IT staff to manage software so you can focus on what your company does best. Another benefit of SaaS that is relevant to today’s business is that SaaS is considered the best option for remote collaboration. With SaaS, your applications can be accessed from any geographic location and your company is not responsible for managing the hardware.
Each cloud computing service model has different advantages when considering which model is best for your business needs, projects and goals.
While IaaS gives you full control over your infrastructure, some businesses may decide they don’t need to manage their applications and infrastructure themselves. IaaS is considered a good fit for SMEs and startups that do not have the resources or time to purchase and build infrastructure for their own network. Also, large companies may prefer to have full control and distribution of their infrastructure, so they can choose powerful tools for IaaS as a paid and remote option. A disadvantage of IaaS is that it is more expensive than PaaS and SaaS cloud computing models, but it reduces costs in the sense that it eliminates the need to deploy hardware on premises.

PaaS is a good choice if you want to reduce time to market due to remote flexibility and accessibility of your application. So, if your project involves multiple developers and vendors, each can get quick access to computing and network resources through PaaS. PaaS may also be used by a team of developers to test software and applications.
SaaS is a viable option for small companies that need to start e-commerce quickly, or for short-term projects that require quick, easy, and cheap collaboration from both.
