Four Layers of Cloud Computing Architecture

  1. The Hardware Layer

    These strata are responsible for handling the physical assets of the cloud. These physical assets could include switches, servers, routers, cooling systems, and power.

  2. The Infrastructure Layer

    These strata are also referred to as the virtualization strata. The infrastructure strata create a pool of storage capacity and computing resources by dividing the physical resources. This division is done by utilizing virtualization technologies such as VMware and KVM.

  3. The Platform Layer

    The platform strata are based on top of the infrastructure strata. The composition of this strata is made up of operating systems and the required structures.

  4. The Application Layer

    These strata consist of real cloud provisions. These provisions are utilized for Web Services, Business Applications, and Multimedia Services


What are the Components of Cloud Computing Architecture?

  • Front-end platform: This platform consists of mobile devices, small clients, and big clients.
  • Back-end platform: It comprises of storage and servers.
  • Cloud-based delivery: This refers to anything that the cloud service provider is offering to the end-users from the cloud. This is done through some platforms, software, and infrastructure.

What You Should Know About Front end Architecture

Everything that the end-user interacts with is comprised of the front end platform. It is a wider collection of different sub-components that collaborate to provide the user interface. The front-end architecture makes up an important part of how the end-user connects to the cloud computing architecture. This architecture consists of components such as web applications, local networks, and web browsers.

Main Front end Architecture

Below are certain components that comprise the main front-end architecture:

  • Software

    The software component in the front end architecture is the software that operates on the user’s side. The software component in the front end architecture basically makes up the client-end applications or browsers.

  • User Interface

    These components refer to all the elements that the end-user access in order to process requests or execute any function on the Cloud. Examples of common cloud-based user interfaces include Gmail, Google Docs, etc.

  • Client System or Network

    This is an important part of the front end platform. It refers to the hardware at the end user’s side. This component can be any input device or PC. When it comes to cloud computing architecture, the client-side system does not need any super ability in order to process the heavy data. The cloud has the capacity to store the whole heavy data and also process it.

What You Should Know About Back end Architecture

It is the duty of the back end architecture to support the front-end platform. It consists of the hardware and storage components and they are both located on a remote server. It is the function of the cloud service provider to oversee and manage the back-end cloud platform.

Typically, the back end cloud architecture should usually be robust. This is because it contains the entire infrastructure on the cloud.

Components of Back end Architecture

Below are the basic components of back-end cloud architecture:

  • Storage

    The data of a cloud application resides in the Cloud storage. Different Cloud service providers offer different data storage. One thing they all have in common is a dedicated section for cloud storage. Examples of storage are hard drives, Intel Orange Optane DC Persistent storage, solid-state drives, etc.

    The hard drives in the server bays form storage in the cloud backbend architecture. Particularly in a cloud computing architecture, the software divides the drives according to the needs of the OS in the cloud. This is done in order to operate a plethora of services.

  • Security

    This is a crucial aspect of any cloud computing architecture. Security structures are developed by keeping the debugging process in mind. Debugging would not be any much of a problem when the need arises.

    In order to make sure security is guaranteed in a cloud computing system, the first thing to do is constant storage backup. Thereafter, you can affect virtual firewalls and other necessary elements that are critical in cloud security architecture.

  • Cloud Runtime

    This concept refers to where the services run. It is synonymous with a cloud operating system where virtualization-related technology is utilized. The benefit of virtualization on cloud architecture is that it enables multiple runtimes on the same server.

    When you utilize virtualization software to create runtimes, they are called Hypervisors. Examples of top hypervisors are VMWare Fusion, Oracle VM for x86, and Oracle Virtual Box, etc.

  • Application

    This is a prominent aspect of the back-end architecture. It entails the user interface that the back-end platform provides the end-user with, in order to send queries. This aspect of the back-end platform is responsible for addressing the client’s demands and needs.

  • Infrastructure

    This refers to the system that directs all cloud software services. The workloads of the clients will always determine the infrastructure models. Examples of the infrastructure are Graphics Processing Unit (GPU), the CPU, Motherboard, accelerator cards, network cards, etc.

  • Service

    The whole back-end cloud architecture receives utility from this essential aspect of the back-end cloud architecture. It is the function of the Service to manage every task that operates on the cloud computing architecture.

    Some of the cloud services include web services, storage, and app development environment. It is necessary to also mention that service can carry out a vast range of functions on the cloud runtime.

  • Management

    If the function of the management software to distribute certain resources to certain tasks. It is tasked with the smooth operation of any cloud architecture without any errors.

    In technical jurisdiction, management is the ‘middleware’. This means that it harmonizes between the front-end and back-end platforms in a cloud computing architecture.

  • Internet

    The Internet is an avenue through which front end and back end platforms can interact and communicate with each other.

What Is Cloud-based Delivery?

As earlier expounded, cloud-based delivery is any form of operation or function that a provider can offer through infrastructure, software, and platforms.

Therefore, if your business uses Google Drive or Office 365, then you are making use of cloud-based delivery. In addition, other cloud-based delivery subscriptions like Platform-as-a-Service (PaaS), Infrastructure-as-a-Service (IaaS), etc., are made possible.

These are just a few of the different subscriptions an individual or organization can purchase in order to use the software that is commonly referred to as Software-as-a-Service (SaaS). This is all thanks to technological innovations like virtualization and hypervisors.

You should know that Cloud-based delivery can be done both privately and publicly through the Internet. In fact, it can be retained within an organization’s network when delivered over an intranet. A combination of both is also possible.

Software as a Service (SaaS)

This cloud computing service is also referred to as cloud application services. This delivery model involves the provision of cloud computing services through authorized software or subscription.

It is not necessary for the end-users to purchase or install any hardware for this cloud-based delivery model in their respective locations. This is because in most cases, SaaS applications operate directly via the web browser. This consequently eliminates the need to download or install the applications.

Below are some popular examples of SaaS:

  • Google Apps
  • Salesforce Dropbox
  • Slack
  • HubSpot
  • Cisco WebEx

Platform as a Service (PaaS)

Platform as a Service can also be referred to as cloud platform services. In a way, it possesses certain similarities with SaaS. However, the point of divergence is that PaaS offers a platform for the creation of software. On the other hand, SaaS enables access to software over the Internet without the requirement of any platform.

The essence of PaaS as a cloud-based delivery model is to provide the end-users with the opportunity to create, operate, and also manage apps on the cloud computing architecture. In this delivery model, a third-party service provider organizes the hardware and software components.

Examples of PaaS are listed below:

  • Windows Azure
  • Magento Commerce Cloud
  • OpenShift

Infrastructure as a Service (IaaS)

It can also be referred to as Cloud Infrastructure Services. Here, this cloud-based delivery model supports computer hardware such as storage, data center space, and networking technology as a service. It further helps to deliver virtualization technology and operating system. It is the responsibility of Infrastructure as a Service to manage middleware, application data, and runtime environments.

Examples of Infrastructure as a Service Includes:

  • Amazon Web Services (AWS) EC2
  • Google Compute Engine (GCE)
  • Cisco Metapod

What is a Cloud Services Network?

The cloud services network enables the end-user to develop a data center or to access the service provider’s data center. This will help the end-user to have on-demand access to different resources such as services, server, application, network, and storage.
