Cloud Architecture
The process of integrating individual technologies to create clouds—IT environments that abstract, pool, and share scalable resources across a network—is known as cloud architecture.
The cloud computing architecture is made up of two parts: the front end and the back end.
Front-end
The front-end infrastructure of a cloud computing business platform is essentially everything with which the end-user interacts. The user interface is the result of a larger integration of various sub-components.
User Interface

The user interface is essentially the familiar, everyday interface that you encounter on a daily basis. The cloud creates a unified environment in which end users can complete tasks without ever having to launch any software on their local machines.
Software

Front-end software architecture is what runs on the user's end. Client-side applications or browsers are in charge of presenting data to users in frontend software architecture.
Client Device or Network

The client-side device is the hardware on the end user's end. It can be any input device, such as your mouse, keyboard, or sound card, because it is an essential component of the frontend architecture.
Back-end
The back-end architecture empowers the front-end architecture. It is made up of hardware and storage that are located on a remote server.
The following are the important components of a strong backend cloud architecture:
Application

In the backend, an application is a piece of software or a platform a client can use. It means it delivers the service at the back end under the client's needs.
Service

Backend services relate to the three main categories of cloud-based services: SaaS, PaaS, and IaaS. It also controls which services the user has access to.
Cloud Runtime

Cloud Runtime in the backend refers to providing of execution and runtime platform/environment to the virtual machine.
Storage

Storage in the backend refers to providing flexible and scalable storage services and managing stored data.
Infrastructure

Cloud Infrastructure in the backend refers to hardware and software components of the cloud-like, including servers, storage, network devices, virtualization software, etc.
Management

Management in the backend refers to the management of backend components like applications, service, runtime cloud, storage, infrastructure, and other security mechanisms, etc.
Security

Backend security refers to the installation of various security techniques in the backend to provide secure cloud resources, systems, data, and infrastructure to end-users.
Internet

The internet connection serves as a conduit or bridge between the front and back end, allowing interaction and communication.
What is the Cloud Landscape?
Clouds are widely available, and they have an impact on our daily lives! Emails, social networking, retail apps, and financial transactions all rely on the cloud in some form. Cloud computing is an on-demand delivery of IT resources via the internet with pay-per-use service charges.
Instead of purchasing and maintaining products and services, you can pay as you use a cloud computing service. It saves you the time, effort, and money of doing it all yourself!

In layman's terms, cloud-based delivery refers to anything we provide to end-users via software, infrastructure, and platforms from the cloud. The following models can be used to supply cloud computing services:
Infrastructure as a Service (IaaS)
This approach provides computer hardware as a service, such as networking technology, servers, storage, and data center space. It also entails the provision of virtualization software and an operating system.
Platform as a Service (PaaS)
This paradigm provides a platform for end-users to design, run, and administer cloud-based applications. A third-party service provider provides hardware and software tools in PaaS.
Software as a Service (SaaS)
Cloud computing services are available as licensed software or as a subscription. End-users are not required to purchase or install hardware at their sites under this delivery model.
You’ll be surprised to know the popularity of these models amongst today’s deployed businesses:
- IaaS has a market share of around 12%. (up from 6 percent).
- PaaS is currently the most popular model, with a market share of around 32% and a projected increase in 2020.
- SaaS accounts for roughly 24% of all enterprise workloads (up from 14 percent in 2016).
With adoption rates like these, cloud computing is quickly becoming the norm, and many businesses are abandoning on-premise software entirely. This now must make you more curious about today’s discussion.
Cloud services reduce operational costs and provide the necessary technological resources for early and mid-stage startups as they scale. Cloud computing services enable the seamless development of critical business objectives such as product development, sales, marketing, record-keeping, and others.
IaaS vs PaaS vs SaaS
To better understand them, we can compare the three terms to modes of transportation.
IaaS is similar to renting a car. You do not own it, but you have the option to upgrade or change cars whenever you want.

PaaS is similar to taking a taxi in that you tell the driver where you want to go but do not drive the car yourself.

SaaS can be compared to public transportation, which has predetermined routes and combines rides with other people.

Now, let us look at the main differences between them:
Unlike traditional solutions, which require you to manage your own IT infrastructure and in-house software, IaaS allows you to pay as you go for storage, networking, and virtualization. Furthermore, PaaS includes additional services such as web-based hardware and software development tools. And, by "renting" full software solutions through SaaS, you get the highest level of vendor management.
How Businesses can Grow using Cloud Landscape?
Below are the mentioned benefits businesses can take advantage of using Cloud Services:

Be more productive
Cloud computing improves productivity in a number of ways. For example, you can use your accounting software to run reports to determine which products or services sell the best and which sales reps generate the most revenue.
The instant availability of accurate and up-to-date business information makes it easier to identify and correct inefficiencies within your organisation.
Keep business data up to date
Cloud computing makes it easier to keep data and records from all departments in a single place. When a business related app connects to the central database, it gets the most recent version.
Scale as necessary.
Before investing in an on-premises IT system, you must be certain that you will use it to its full potential in order to justify the significant upfront investment. It also necessitates months of planning and specification.
It's not the same with cloud computing. You can quickly expand or reduce the cloud services you use, and you only pay for the storage, apps, and computing power you need.
Automate more tasks
Cloud task automation reduces employee workloads, giving them more time to be productive. Productivity software plans out the work that needs to be done in the coming days and weeks and alerts team members well before something is due, allowing employees to accomplish more while requiring less day-to-day management.
Future of Cloud Computing
Businesses today are looking for new ways to grow and achieve their objectives. This business will continue to expand in the future thanks to cloud computing. Cloud computing is powerful and expensive, and it will continue to grow and provide numerous benefits in the future.

Cloud computing is extremely cost-effective, and businesses can use it to expand. Cloud computing has a bright future and will benefit both the host and the customer.
Below are the mentioned reasons why Cloud has a bright future:
Speed and Agility
Every business is under pressure to respond to changing business conditions more quickly. Traditional IT processes, unfortunately, are inadequate for today's speed. Provisioning resources typically takes weeks or months, slowing the business's reflexes. Because cloud computing makes resources available in minutes, so businesses can respond to new market developments more quickly.
Cost Effective
Another harsh reality of traditional IT infrastructure is its immense cost. Infrastructure necessitates physical resources such as servers, storage, and a network. However, those resources have significant operating costs, including headcount, facilities, and power. With cloud, businesses only have to pay as they use the services.
Frequently Asked Questions
What are the use cases of the IaaS model?
Disaster recovery, Cloud bursting, Automated scaling and cluster management or High-performance computing (HPC), and Big Data analytics.
What exactly can a client expect from the PaaS model?
PaaS provides a predefined and ready-to-use set of building blocks for composable applications, such as middleware, application servers, and development tools. PaaS enables your developers to spend more time developing the application while the provider manages the infrastructure.
Is Amazon AWS a Platform as a Service (PaaS)?
Not only PaaS, but AWS (Amazon Web Services) also is a comprehensive, ever-evolving cloud computing platform offered by Amazon that incorporates infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) offerings.
Is YouTube a type of cloud service?
According to Thomas Kurian, Google's cloud division leader, parts of YouTube are moving to the Google Cloud Platform. Along with other top Google properties such as its eponymous search engine, the popular video app has run on Google's own infrastructure separate from its cloud.
Conclusion
