How do IaaS, PaaS, and SaaS Relate to Cloud Hosting?

Cloud   is no longer a buzzword. It is essential for all businesses. With automatic updates, exclusive features, affordability, and computing resources, Cloud is becoming a part of almost all businesses. But when you make your decision of migrating to the Cloud, you must understand which cloud computing model to go for. 

IaaS, PaaS, and SaaS are the most popular cloud computing models that companies prefer when they consider opting for Cloud hosting

To achieve the benefits, businesses can either go for any of these models. They can also use the combination of these cloud computing models. It completely depends on your business requirement. 

To achieve the desired results, you must have a deep understanding of what IaaS, PaaS, and SaaS are. And, how are they beneficial for your business? 

IaaS- Infrastructure as a Service 

IaaS is a model that helps businesses avoid the hassle of procuring data center infrastructure and physical servers. In this model, the service provider offers computing resources like servers, virtual machines, operating systems, hypervisors, networking hardware, storage, In short, it offers businesses cloud-based alternatives in place of on-premise infrastructure. 

Using the IaaS cloud computing model, your business will be able to gain real-time insights and save big on the cost of infrastructure. The delivery of the services takes place over the Internet. With this model, you have complete freedom to pick the resources as per your business requirement. This model is not just cost-effective but can also cater to the needs of multiple users. 

Advantages of IaaS 

  1. It is a much safer option than investing in huge infrastructure and offers immense reliability. 
  2. You can easily scale up and down your resources as per your business requirement. 
  3. It comes with a pay-as-you-use model that means no hidden cost is involved. 
  4. Since the data stays on the managed cloud, you don’t need to worry about the point of failure. 
  5. It frees you from the hassle of buying and maintaining hardware. 

PaaS- Platform as a service

PaaS offers a cloud environment that allows users to build, manage, and deliver apps. Although it functions very much like IaaS but comes with additional tools like a database management system, and others. A PaaS service provider will provide the client with essential hardware and software over the internet which developers can use to design and create applications. 

The delivery of PaaS services takes place over the internet. In comparison to IaaS services, PaaS adds a layer of managed services to it. Similar to IaaS, PaaS providers’ infrastructure includes servers, storage, and networking but also middleware, tools for development, database management systems, and more. 

Advantages of PaaS

  1. It offers both time-effective and cost-effective solutions to the developers. 
  2. It gives developers the freedom to focus on the creative side and development.
  3. You don’t have to worry about the software updates and security patches. 
  4. It doesn’t require extensive knowledge to operate the PaaS services. 
  5. It is future-proof and offers you access to state-of-the-art data centers. 

SaaS- Software as a service 

SaaS applications are used by IT professionals, business users, and individuals. The products cover everything from personal entertainment, such as Netflix, to advanced IT tools. Unlike IaaS and PaaS, SaaS is often marketed to both B2C and B2B users. 

Applications that run on a SaaS provider’s servers are known as SaaS applications, web-hosting applications, on-demand applications, or hosted applications. The provider manages applications’ security, availability, and performance. 

An independent software vendor (ISV) may contract third-party cloud providers to host an application as part of a software as a service (SaaS) distribution model. An application using the SaaS model is hosted in the cloud. Software providers either host applications and related data on their servers, databases, and networks, or they contract cloud providers to host the application in their data centers.

Advantages of SaaS

  1. SaaS services save you money because they automatically scale up and down based on usage levels.
  2. Using SaaS allows workers to access data and apps from any computer or mobile device with Internet access. 
  3. To protect your mobile computing system, you don’t need to hire a security expert.
  4. Many SaaS apps can be run directly from a web browser, which eliminates the need for downloading and installing software, although some apps may require plugins. 
  5. SaaS services also save you money because they automatically scale up and down based on usage levels.

You just need to find the cloud computing model that will suit your requirement just right. So, wait no more and migrate to Cloud hosting or any of these cloud computing models to take your business to new heights.
