Using cloud computing to develop businesses requires a solid foundation of knowledge as well as having a well-prepared plan. One of the most important thing is the decision to choose between infrastructure as a service (IaaS) or Platform as a service (PaaS). IaaS and PaaS, while there are many similarities, we can find a few important differences between the two platforms to help users get the most appropriate choice. Here are some solutions to solve this problem.

What is Iaas?

IaaS is a model in which the use of enterprise hardware such as servers, storage and core networks are delivered as a service. Enterprises will provide on-demand services, while empowering customers to config the operating system, software and database.

IaaS is one of the core values of cloud computing. If businesses want to fully integrate its work to the cloud, the functions and duties of the hardware will be moved up here. The main attraction of using IaaS solution is that businesses can scale up or down depending on its needs and capabilities. IaaS also contribute to reducing the cost of investing in hardware as well as the costs incurred for the purchase and use of the archive.

What is PaaS?

While IaaS provides external hardware to create a storage environment, PaaS provides a platform for developing applications that can be distributed over the Web. That makes PaaS capable of allowing multiple developers to work on source code simultaneously.

In the PaaS environment, developers can test, develop, deploy and host applications through an online service. This online service allows developers to focus more on developing applications rather than hardware maintenance, which is inherently supported by PaaS. IaaS and PaaS are both helping to reduce the investment cost, allowing an IT environment more focused on strategy rather than hardware maintenance.

Where Things Get Complicated

Contrary to the thinking that IaaS and PaaS are significantly different, the 2 platforms have a lot of similarities. This is the result of the integration of the existing tools with the IaaS services. These tools allow simultaneously deploy various types of different cloud environments.

So, in theory, enterprises can create a cloud like what PaaS can provide. Enterprises can test, deploy, develop, host and maintain applications within the cloud while maintaining the required computational, storage and network your IT environment in another cloud.

This has led to speculation that the IaaS and PaaS will eventually be combined into a unified model. However, the use of IaaS to develop into PaaS waste more time than using an available PaaS cloud.

When You Should Use IaaS

IaaS provides many benefits, but a structural change in infrastructure can cause many difficulties. IaaS model is ideal for companies wishing to expand the scale of resources quickly and often. IaaS can meet the demand for these jobs require a high strength immediately, and can arrange for a dilated softer period

These companies that may not have much capital can also benefit from IaaS. When businesses do not need to invest in hardware, it will be easier by saving operating costs and maintenance. This allows companies to focus more on strategy than maintaining the infrastructure.

Fundamentally, IaaS is an ideal solution for any company looking for an effective way to expand the infrastructure needs according to users’ needs. Instead of working too much or too little, IaaS makes everything easier because it can be customized according to the different needs. However, these benefits can be offset if a company can build a huge repository of personal data.

When You Should Use PaaS

PaaS excel when multiple developers work on a single application. It allows simultaneous use of a single source with the ability to automatically test and deploy.

Unlike IaaS, PaaS typically requires the use of a specific and exclusive language. This can cause a problem if a company wants to switch to different PaaS providers. With this disadvantage, businesses should better study PaaS vendors thoroughly before applications are developed.

Choosing the Easiest Path

With both IaaS and PaaS services, now there are many benefits to be achieved, and also need to think about using the platform that best suits company situation. While IaaS focuses more on storage, networking and computing, IaaS providers are starting to offer tools that allow implementing similar experiences with PaaS platform. When these tools can be developed into a specific PaaS platform, the benefits that it brings can be more than the usual PaaS platform.
