Cloud Architecture: meet the three layers and the 3 types
Cloud architecture is the ideal way how you define and configure a particular model of functional interaction of so-called cloud layers – divided into three levels, IaaS, PaaS, and SaaS – to reach the desired goals for the organization that is creating a cloud system.
The layers are considered as abstractions, which are used for administrators, developers, architects and others involved in a project of architecture and cloud development can articulate your ideas, plan actions and evaluate the decisions taken.
In this post, we’re going to get more details of each of the three layers of the Cloud architecture, in addition to clarifying and define three types of cloud.
The 3 LAYERS of the CLOUD ARCHITECTURE
When planning the design and the development of a cloud system cloud layers are used figuratively, in the same way, that usamosmetáforas in our day to day to explain better and more precisely what we want to transmit to others.
Note that the three acronyms refer to a service (usually charged per period) which, depending on the level and usage model, involves different objectives and functionalities.
See more details about each of the layers of the Cloud architecture and its advantages:
IAAS: Infrastructure as a Service
Infrastructure as a service means and encompasses the hardware, such as network components, drives, storage devices, servers, and other physical elements of the system.
On this layer of Cloud architecture, the client or user takes advantage of physical estainfraestrutura provided to control operating systems, store files, and applications.
PAAs: Platform as a Service
Platform as a service. Here the architecture and cloud development platform for deals, that is: the structure of the application and operating systems accessed.
In fact, it would be the way to make cloud applications using the tools and languages compatible with the standards of the company offering the service.
Is a service tailored for small businesses develop software,
SaaS: Software as a Service
The level of Cloud architecture called Software as a Service is that with which you interact when using Google Apps or even Facebook and LinkedIn.
This is the layer that the applications developed are made available to final customers, with or without collection of fees for the service, depending on your level of sophistication or monetization model.
TYPES OF CLOUDS
Now that you already understand the Cloud architecture levels meet their three guys.
Protected by security measures, such as firewalls, private clouds are for the indoor use of corporations who don’t want to risk your data, and sensitive information stays vulnerable.
It is the same scheme of a public cloud but restricted to members of an organization.
As the name implies, it is a mixture of the two previous concepts. The services are shared between public and private space, and management responsibilities are divided in the same way.

We can conclude that the Cloud architecture must determine how to combine each of these elements cited to define the best system performance or business wants to structure, integrating the best way each of the layers.
A good architecture and cloud development cannot be interpreted simply as the integration of several servers. It is necessary to promote managing information flows, with constant monitoring, security and guaranteed mediated the ability to meet the disruptive users.
