Cloud Computing Architecture [With Components & Advantages]

What is Cloud Computing?

Cloud is the most popular service in today’s world. Almost everything is stored on the cloud due to its long list of benefits. Services like servers, databases, networks, cryptocurrency, analytics, etc. are hosted through the cloud over the internet. Cloud is famous for its on-demand availability and storage. The clouds are basically data centers present over the internet.

Cloud means ‘distributed computing;’ the data centers are distributed over the internet, and you can access them using the internet at any time from anywhere with no clustering due to space availability issues. Instead of buying the data centers and infrastructure, organizations can rent different cloud computing components from a cloud service provider and access anything with it. The prices are nominal and budget-friendly.

The simplest example of cloud service is the backup of photos from your smartphone to the cloud. A large amount of data is hosted on the internet, and you can access it whenever you need it. Your smartphone gets rid of the extra storage without deleting your captured memories.

Cloud Computing Architecture

Architecture refers to the actual building blocks of any system. Cloud computing architecture includes various cloud computing components, bundled up to form a fully functional system.

It can broadly be classified into two parts:

Front End

It is the user interactive platform, and it’s ideally for the users to provide their requirements. It includes local networks, browsers, and web APIs and development kits.

The front end provides a menu for the user to convey their needs and perform tasks on the cloud.

The software for the client’s end consists of client-based applications and browsers.

The main hardware part at the client’s end is the Client Network. The front end is easy to use, and the format is available for users to get hassle-free services. The user need not take care of the back end processes. Everything will be provided with a click.

Back End

The back end building of the cloud draws in the front end plan. It includes hardware and limits and is arranged on an inaccessible specialist. The cloud controls this back end cloud plan in the center. Back end cloud building should be generous and reliable, as it sustains the whole system using the cloud. The prime pieces of back end cloud building are: 

  • Application: The application is a significant part of the back-end designing. It insinuates the UI that the back end offers to the end customer to send requests. This layer of the back end manages the client’s sales and necessities. 
  • Organization: It is a captivated zone of back end cloud designing. Thus, it adds functions to the entire back end plan. The organization handles each endeavor that abruptly spikes for the disseminated registering system. A segment of the cloud organizations is application improvement in terms of condition, storage, and web organizations. 
  • Cloud Runtime: The term ‘Cloud Runtime’ is the spot that associations run. No doubt, a cloud working structure. Absolutely when we make progressions with the assistance of virtualization programming, they are called Hypervisors. A hint of the basic hypervisors is Oracle Virtual Box, Oracle VM for x86, VMWare Fusion, etc. 
  • Cutoff: Distributed capacity is the place where the data of a cloud application stands or resides. In any case, all of them have a typically submitted locale for passing on limits. A pattern of the instance of the cutoff is solid-state drives, hard drives, Intel Optane DC Persistent limit, etc. The specialist cover structure is taken care of in the cloud back end arranging. Additionally, especially in a circumnavigated area taking care of the structure, the thing scatters drive as indicated by the necessities of the OS in the cloud to run swarm affiliations.
  • Establishment: The motor that arranges all the cloud computing components is called structure. It wires the CPU, Motherboard, Graphics Processing Unit (GPU), network cards, invigorating pro cards, and so on. The foundation models dependably rely on the uncommon loads of the customers.

Components of Cloud Computing Architecture

There are several components of cloud computing:


It is also known as Virtual Machine Monitor. It acts as a virtual operating system for the user, allowing them to manage the guest operating system to use the cloud. It consists of software, hardware, and firmware that combine and run the virtual machine to use the cloud.


The administration programming assigns explicit assets to explicit undertakings and is answerable for the impeccable working of any cloud condition. In specialized terms, the executive is the ‘middleware,’ and it arranges between the front end and back end engineering in a distributed computing framework. The executive’s programming comprises different plans and the systems that help build the cloud exhibition.

This administration programming gives numerous highlights, for example, on-time conveyance of capacity, legitimate security, untouched access, and numerous different offices. This is one of the significant pieces of Cloud Computing design. One of the significant highlights of this is the consistent examination, the executives of managing calamity, and emergency courses of action.


Every cloud system needs to be deployed first. It consists of all mandatory installations and configurations for the cloud. There are three models of deployment to initiate it.

  • SaaS – Software as a Service 

Offering circulated processing organizations through approved programming or participation. In this transport model, the end-customers don’t need to buy or present any gear in their territories.

  • PaaS – Platform as a Service

PaaS model offers a phase that allows the end-customers to make and run similarly as administer applications on the cloud. In PaaS, an outcast master association empowers hardware and programming instruments.

  • IaaS – Infrastructure as a Service 

This model energizes PC hardware like frameworks organization development, laborers, accumulating, and worker ranch space as a help. It moreover fuses the movement of virtualization advancement and working system.


The network is the most important component of the architecture. It binds the connection of the cloud. It connects the front end to the back end.

Benefits of Cloud Computing

  • Speed and Latency

The cloud services increase latency, and hence, the speed increases. Speed is the need in today’s times. Cloud showers us with fast speed technology.

1. What are the disadvantages of Cloud Computing?

Despite its benefits, it also has a fair share of issues. Cloud downtime is the biggest disadvantage of cloud computing. Like any other setup, a cloud is likely to experience technical glitches such as downtime, outage, and reboot. These issues can cripple the business processes and can cause heavy damage also. Implementing effective plans for cloud downtime could be an effective resolution. The next disadvantage of cloud computing is the limited access. A cloud service provider manages, analysis, and monitors cloud infrastructure. As a customer, the access to infrastructure is limited. You may be able to work with data services, monitor the cloud, etc. Still, you will not be able to regulate administrative tasks like accessing servers, managing firmware, and installing regular updates.

2. What are the standard ways to minimize risks on the cloud?

Security breaches are expected; however, it is important to understand how to mitigate the risks. You must be aware of how the cloud provider model works as it will also be your responsibility to watch your network. Implementing security is the next way to keep away from security risks. Next is encryption. Encryption should be used anywhere and everywhere possible. For all the sensitive data and information, multi-factor authentication must be enabled. Finally, following a risk-based approach is the only way to ensure protection to secure assets and data.

3. Is the cloud right for a business?

Companies are rapidly shifting to the cloud due to several reasons. The major contributors behind the shift are factors such as scalability, flexibility, etc. However, from an operational point of view, you must analyze all the reasons to evaluate if you need to transition to the cloud. Scaling cloud could be quick, but you must have answers to whether or not your business demands it. Cost, technology landscape, ease of migration, and service are the areas that will benefit the most; hence, you must weigh your IT setup accurately. Once you have answers to all the questions, moving your business to the cloud will be easy.
