Components of the Backend Platform
Application
The backend software is the backbone the client interacts with from the front end. It handles and satisfies client requests and enables them to meet their needs.
Service
The service acts as the central core of cloud architecture, assuming responsibility for executing and managing a wide range of tasks within a cloud computing system. It governs the availability and allocation of accessible resources, like application development environments, storage, and web applications.
Storage
The storage element within the backend architecture comprises the data required to support application operations. Cloud storage solutions, which can vary across different providers, mainly offer highly scalable and adaptable storage services exclusively designed to handle extensive data volumes within the cloud environment. These storage options may include diverse technologies such as hard drives, persistent disks, or solid-state drives within server bays to ensure efficient data management.
Management
Effective management is crucial in cloud service models. It necessitates real-time resource management as per the user’s preference. Using management software or middleware facilitates seamless coordination between frontend and backend components. It helps allocate resources for the accomplishment of specific tasks. Besides middleware, this software has numerous functionalities like data integration, usage monitoring, disaster recovery, and application deployment.
Infrastructure
Cloud infrastructure encompasses essential hardware components such as CPUs, GPUs, network devices, and associated software, driving cloud services. In contrast, cloud architecture outlines the organisational blueprint for cloud resources and infrastructure.
Security
With the increasing adoption of cloud computing, prioritising robust security measures is a compulsion to safeguard data, platforms, and applications. Effective planning and design of data security, network security, and redundancy data loss prevention ensure visibility and downtime. Essential security practices may involve regular backups, debugging, and the implementation of virtual firewalls, to strengthen the overall security of cloud environments.
Internet
The internet connection serves vitally to mend the gap between the frontend and backend components of a system. It facilitates seamless communication and interaction between the front end and back end, enabling the flow of data and commands between the two.
Working Principle of Cloud Architecture
The integration of various components synergistically forms a cohesive cloud computing platform in cloud architecture. It enables users seamless and instant access to numerous services and resources.
The backend encompasses an extensive assortment of cloud computing resources, data storage, services, and applications provided by a cloud service provider. A network serves as the vital link connecting the frontend and backend components of the cloud architecture. This facilitates seamless data transmission between them. Whenever users engage with the front end, representing the client-side interface, their queries are relayed to the back end through middleware. Within the back end, the service model takes charge, executing the requested task or operation with precision.
The available service types differ according to the cloud-based service or delivery model the user chooses. Primarily, three cloud computing models are available, sufficing a varied range of services.
Infrastructure as a Service (IaaS)
Through this model, users can access various cloud infrastructures like storage, networking, and servers. This removes the need to manage, procure, and maintain on-premises services.
Platform as a Service (PaaS)
This model presents a computing platform that encompasses essential software tools and infrastructure, which equips users with an environment that helps to create, deploy, and oversee applications effortlessly.
Software as a Service (SaaS)
It is a model that presents cloud-based applications that service providers exclusively provide and maintain. This eliminates the requirement of local software deployment from the side of end users.Â
Layers of Cloud Architecture
Cloud computing architecture becomes easier to comprehend when all its components are segregated into layers stacked upon one another, forming a cloud platform. Below are the fundamental layers of cloud architecture you should know.
Hardware
The hardware, like storage, servers, and network devices, besides other hardware components, is the source of power for the cloud.
Virtualisation
It is an abstraction layer that curates a comprehensive virtual representation of storage resources and physical computing. This enables efficient resource utilisation and facilitates the sharing of resources among multiple applications.
