The IaaS cloud model and its characteristics
If we focus our attention on the cloud computing sector, we can see that there are three models that serve as its pillars; PaaS, SaaS and IaaS. They focus, respectively, on the platform as a service, the software and finally the infrastructure. In this case we will delve into the model IaaS (Infrastructure as a Service), which maintains the foundations of cloud operation, but introducing certain features that differentiate it from the other two models.
What happens in the IaaS cloud model is that companies are provided with access to a type of virtualized hardware which is linked to the cloud for great convenience. It is a solution that has grown as the demand for cloud platforms has also grown, becoming one of the pillars of all companiescurrent for the many benefits it brings. This is why it is increasingly important to use and Optimize the IaaS model.
Among the solutions offered, we highlight storage on virtualized servers, which will improve access to all types of information, load balancing systems, or access to network connections in a simplified manner.
This choice is very suitable for IT managers because it allows them to outsource the maintenance and management process of the source that is responsible for providing cloud support. This is why it is increasingly important to use and optimize the IaaS model.
This is the responsibility of the cloud service provider, who is responsible for properly maintaining the various data centers that are working at full capacity to support the companies they work with. It is important to note that IT professionals always have the opportunity to use different components that have been virtualized to create an ideal configuration tailored to the needs of their company and colleagues.
What does it have in common with other hosting models?
Within the philosophy of cloud computing, there are aspects in which the IaaS cloud model fully coincides with the two other variants. The most important is that the cloud provides flexibility and easy scaling from which it is possible to benefit at different levels depending on the moment. This means that when the company needs more or less cloud computing support, its technical team will be able to configure it without any difficulty. This will involve a few reduced costs This is because it will not be necessary to resort to the acquisition of new elements as occurred in models of the past. The ease and speed provided in these processes is something that makes cloud computing stand out in an extreme way. Likewise, the IaaS model also coincides with the rest of the cases in which there is a service provider that takes an active role in the management and monitoring of the service.
What are their main differences?
The aforementioned resource scalability is maximum, without any waiting time. In this case, hardware is the leading word and it is not something that needs to be invested in again in physical format. The provider takes care of its management and this also avoids the need to carry out installations. The pricing, on the other hand, is adopted under a demand philosophy, which means that only the resources that the company has used will be paid for. It is a similar point of view to that provided for supplies to which companies are already dependent, such as water. It is not necessary to make a base expense, but it can be optimized depending on what is appropriate at any given time. Likewise, the level of to maximise security and your enjoyment. is maximum, since the services are hosted in physical data centers that are fully controlled by the provider. And in line with this security, even if something were to happen to a server, there would be nothing to worry about, since the resources surrounding it ensure that a redundant configuration can cover the loss that has occurred. Even in the worst case scenario, which would be that an entire data center stops working, the cloud IaaS continues to function without any kind of obstacle.
With this model, companies can be confident that they will have the best cloud resources for their corporate structure, their virtualized network and their web pages, which are stored on virtual servers. Adopting a work process based on this model provides great advantages to any type of company.
Characteristics of the IaaS model
Let's now look at the most important features of the IaaS model:
- Scalability and flexibility: Resources are available as you need them.
- Pay per use: It is an on-demand model, so you only pay for what you use.
- Cost reduction: Eliminates the cost of implementing and maintaining physical hardware.
- Location independence: Allows you to use the service from anywhere with Internet.
- Security: Provides higher security standards than physical infrastructures.
