The Cloud Computing Infrastructure Key Concepts

When it comes to cloud computing infrastructure, the virtualized resources are hosted by an IT department or the service provider and delivered to the users over the internet or a network. Such resources include virtual machines as well as components including a computer, servers, network switches, memory, storage, firewalls, and load balance devices etc.

In cloud computing architecture that refers to the back end and front end of the cloud computing environment, cloud computing infrastructure is comprised of back end components.

Businesses utilize cloud computing infrastructures to run their applications. When compared to subscription-based pricing models and payment structures that enable the users to subscribe to the vendor services for a set price, the cloud computing infrastructure is usually bought with the use of a pay-per-use model. In the pay-per-usage model, users pay only for the consumed services, generally on a weekly, monthly or hourly basis.

Understanding the Cloud Services SaaS, PaaS, IaaS

Instead of purchasing cloud computing infrastructure from certain cloud computing vendors or provider, businesses may also build cloud infrastructure on-premises. Once cloud providers maintain cloud infrastructure, an environment is a public cloud. When organizations who use cloud maintains cloud infrastructure, an environment can be a private cloud. When both user and cloud provider own pieces of cloud infrastructure, an environment is known as a hybrid cloud.

Anyway, choose from the three types of cloud computing services that need you for your company and end-users.

These are three categories of cloud computing services, however, a very simplified way of differentiating these flavours of Cloud Computing is as follows;

SaaS applications are designed for end-users, delivered over the web
PaaS is the set of tools and services designed to make coding and deploying those applications quick and efficient
IaaS is the hardware and software that powers it all – servers, storage, networks, operating systems

Cloud Computing Infrastructure Components 

Cloud computing infrastructure typically consists of storage devices, servers, cloud management software, network, platform virtualization, and deployment software.

  • Hyper visor

It’s a low-level program or firmware that serves as a virtual machine manager. It enables anyone to share a single physical instance of cloud resources between some tenants.

  • Management Software

It helps you to configure and maintain infrastructure.

  • Deployment Software

It helps to integrate and to deploy the application on the cloud.

  • Server

It helps to compute resource sharing and provides some services including de-allocation and resource allocation, providing security, and monitoring resources.

  • Network

It’s the most important component in cloud computing infrastructure. It enables you to connect cloud services online. It’s also possible to deliver the network as a utility online, which only means that the customers may customize the network protocol and route.

  • Storage

Cloud will keep different replicas of storage. If one of the resources for storage fails, it may be extracted from another one that makes cloud computing much reliable and efficient.

Infrastructural Constraints

Some of the constraints that cloud infrastructure must implement are below:

  • Transparency

In cloud computing, one of the premises is that the services are transparently delivered whatever the physical implementation in the cloud. The transparency is a foundational concept in cloud computing. It’s actually another form of virtualization where various resources appear to the users as a single resource. It’s unlikely that single servers or resources will always be sufficed to satisfy the demand for a provisioned resource.

  • Scalability

Scaling up application delivery solutions aren’t that simple as scaling up an app for the reason that it involves configuration or re-architecting the network. Therefore, an application delivery solution is required to be scalable that will require virtual infrastructure so that the resource can be de-provisioned and provisioned easily.

  • Intelligent Monitoring

For you to achieve on-demand scalability as well as transparency required of mega data centre in the cloud, control nodes like application delivery solution will require intelligent monitoring capabilities. It’ll need to understand when a certain server is overwhelmed and once network conditions are affecting the application performance adversely. It needs to determine the services and applications being served from the cloud and understanding when behaviour is outside the accepted norms. While functionality may be implemented externally in a huge management monitoring system, once the control nodes see clients, the state of applications, and the network, it’s in the best position to understand real-time conditions as well as the performance of involved parties without the need of heavy lifting of correlation which would be needed by external monitoring systems.

  • Security

Cloud’s mega data centre must be architect securely. The control node must also be secured. Read more about cloud computing security benefits for online business.

The Basics of Cloud Computing Infrastructure

Clouds may be private or public and provide some IT capabilities as a Service. With this in mind, what does cloud mean when it comes to infrastructure?

While the cloud services may vary in implementation detail, they share common cloud computing infrastructure elements and these include:

  • Multi-tenancy and metering.

Another attribute of a cloud service is that this is consumed by several customers. Cloud management software and cloud computing infrastructure should support the ability to logically or physically segregate the data storage and traffic associated with various customers and to track service usage closely per customer so that the user may be charged for or reported on.

  • Self-service interfaces.

A trademark of cloud solutions is that the users can invoke them through the web interface without the assistance of a service provider. Therefore, an important part of cloud computing infrastructure is support for the web-oriented service application programming interface. Usually, a web portal is made available to the service users and in some cases, the API is exposed to the service users so that they may establish their own apps that call API.

  • Pervasive virtualization.

Without this and the ability to utilize pooled IT resources efficiently and flexibility, it is difficult to imagine cloud computing. Typically, cloud computing infrastructure uses network virtualization and storage and server virtualization.

  • Pervasive automation.

To meet them instantaneously and unpredictable user demands, cloud solutions make use of software, which automates the scaling and provisioning of storage, networking resources, and compute.

Cloud Computing Infrastructure Is More Than a Data Center

An overlooked, yet critical dimension of cloud architecture is public internet. In many cases, end-users interface with cloud services through online and cloud service performance is susceptible to the internet’s inherent variability. It’s true even for the private enterprise cloud services if the users access the service through mobile devices or geographically dispersed.

Today, a lot of companies help private and public cloud operators deliver high-performing cloud solutions online to end-users connecting anywhere across the globe, from any kind of device.
