Cloud Architecture

Home | Cloud Architecture

Cloud architecture refers to how individual technologies are integrated to create clouds : IT environments that mine, pool and share scalable resources across a network. It is how all the components and functionalities needed to build a cloud are connected to deliver an online platform on which to run applications.

Think about building a house: the cloud infrastructure incorporates all the necessary material, while the cloud architecture constitutes the project.

What does a cloud architecture look like?

Clouds are considered Platforms-as-a-Service (PaaS), as a cloud provider provides users with both the platform and the underlying IT infrastructure. To build a cloud platform, it's not enough to separate the processing capabilities from the hardware components, as happens when cloud providers offer a cloud infrastructure to users. In fact, additional levels of development are required to integrate containerization, orchestration, API (application programming interfaces), routing, security, management and automation technologies. To create an intuitive online experience, you also need to plan for user experience design.

While some cloud architectures may vary according to need, most clouds require hardware, middleware, management, and automation software. Most clouds also use virtualization to extract hardware resources in centrally managed data lakes, while some clouds, known as bare metal clouds, connect clients directly to hardware.

Types of cloud architectures

Public cloud architecture: Cloud environments built with resources, which are not owned by the end user, which can then be redistributed to other tenants.

Private cloud architecture: Often referred to as cloud environments dedicated exclusively to the end user, they are typically located inside the user's firewall and are sometimes on premise.

Hybrid cloud architecture: Multi-cloud environments, each with varying levels of portability, orchestration, and management.

Multicloud architecture: IT systems that include more than one cloud, public or private, which may or may not be networked.
