Let's understand when solutions can and should be used, depending on the problems existing in organizations.

How to use IaaS
If you are responsible for a corporate data center, you know that to activate and maintain any application it is necessary to consider absolutely all aspects related to the system's hardware and software.

The first block of concerns includes basic issues such as physical space, power and cooling, as well as the assembly of the entire infrastructure for georgia email list internet access, local network, load balancers and secure remote access. Completing this block, you should think about the servers and storage devices that your application requires.

When we move to the cloud environment, this first block of elements is offered as Infrastructure as a Service (IaaS) . In other words, when you hire an instance or virtual machine as IaaS, you get a server with storage that is connected to a network and you don't need to worry about any physical aspect of all this hardware.

It is up to you to access these machines and install all the necessary software. Major IaaS providers include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

How to use PaaS
We know that for the application to work correctly there are still important issues to worry about, such as the Operating System , its updates, adjustments and protections. We also need some kind of front-end such as HTTP servers or session virtualizers. Finally, we need to install and maintain a database on the available storage device.

When this second block of elements is part of the cloud offering, we are talking about Platform as a Service (PaaS) . PaaS offerings are usually tied to specific development frameworks.

This is important because the operating system, database and front-end issues are adjusted to work well with a given environment. This way, you can hire PaaS to run your .NET, Java, PHP, Ruby on Rails or Django application, among others.

Typically, the PaaS provider offers some environment options for each type of framework and you will have to adapt to these restrictions. This way, you are responsible for developing the application code and you only have to follow some procedures to export this code to the PaaS infrastructure.

All maintenance of the production environment is handled by the PaaS provider, which keeps the entire system completely automated. In addition to Google and Microsoft , other providers are available and scaling an application is very simple.

How to use SaaS
Software as a Service (SaaS) is a complete proposal where you only use the software that the provider has developed. In this case, your only concern is with customizing the software in order to ensure its efficiency and good use.

The vast majority of SaaS offerings are based on web applications that all users access via a browser. Common examples include Google Apps and Microsoft Office 365, where you can purchase cloud-based email services and office applications, or SalesForce and Pipedrive, which offer sophisticated CRM solutions.

Solutions to Different Problems
As you can see, IaaS, PaaS and SaaS serve different purposes and are therefore complementary solutions . If you have a specific application with many particularities, it is likely that only IaaS can serve you in the cloud.

If you have an application developed using the most well-known frameworks on the market, PaaS is likely to be the quickest and simplest way to migrate to the cloud, taking advantage of all the automation that this model offers.

Finally, if your needs fit into off-the-shelf solutions, SaaS offers the fastest alternative to using the cloud.

Orchestration and Automation
For both IaaS and PaaS models, it is essential to analyze the orchestration and automation tools that are available from the provider and how you can interact with them to ensure that the scalability of the solution is as smooth and automatic as possible.

Furthermore, this tool facilitates all tasks related to the high availability of your system and the creation of Disaster Recovery strategies . Offers vary between different providers and generally the most complete and flexible solutions allow your application to be more easily ported to the cloud, enjoying the benefits of this environment more efficiently.
