Cloud computing architecture details all the necessary components and subcomponents that are essential for the effective functioning of cloud computing. Generally, these components include a network, front-end platform, backend platforms, and cloud-based delivery. All these functions work together to coordinate with each other, enabling them to offer on-demand, scalable computing technologies over the web.
With a robust cloud computing architecture, businesses can access affordable, resilient, and scalable cloud platforms. Such systems also ensure seamless business transformation while excelling in innovation and achieving business agility. It also ensures reliability and security while delivering cloud services.
Cloud computing architecture is crucial because it enables businesses to access secure, efficient, and scalable services. As a result, a well-planned cloud architecture is necessary to allow them to meet client demand while achieving business goals with cost-effectiveness and reliability.
Main Components of Cloud Computing Architecture:
Front-End:
The front end also acts as an interface between the cloud infrastructure and the user. It is also known as client-side interface that enables the user to access cloud services. They enable user interaction on one side and custom interfaces on the other. The cloud architecture side that enables user interaction includes command-line tools, client-side applications such as thin clients, mobile applications, and web browsers like Firefox and Chrome.
Backend:
The cloud service provider requires such infrastructure and are very essential components. They include software, hardware, and management systems and play an important role in delivering cloud services. It also serves as an “engine room” for powering cloud platforms, including Microsoft Azure, Google Cloud, and AWS.
The backend responsibilities of cloud computing services include the following,
Load Balancing:
Evenly distributes workloads across various services to prevent overload.
Fault Tolerance:
Importantly, they ensure seamless operation of the system, even during the failure of components.
Service Orchestration:
Play an important role in coordinating with multiple services and ensuring smooth workflow.
Resource Allocation:
Dynamically distributes networking, storage, and computing resources.
Security:
They ensure the implementation of stringent policies for data protection and detect any possible threats.
Cloud Delivery Models:
Importantly, there are three types of delivery models they include SaaS, PaaS, and IaaS.
SaaS (Software as a Service): Salesforce and Gmail, for example.
PaaS (Platform as a Service): Heroku and Google App Engine are some prominent examples in use.
IaaS (Infrastructure as a Service): Examples are Microsoft Azure and AWS EC2
Cloud Deployment Models:
The deployment models determine the accessibility, ownership, and degree of security level of the cloud environment. The deployment model ensures a balance of cost, security, and performance while accessing the data resources to fulfill the organizational demands.
The different types of cloud deployment models include the following,
Hybrid Cloud:
It ensures accessing resources using both private and public cloud platforms.
Public Cloud:
These offer shared resources, allowing multiple users to access the cloud platform. Google Cloud and AWS are some examples.
Private Cloud:
It exclusively allows only a single organization to access the resources. Although it incurs high costs, there is much security.
Community Cloud:
It ensures the sharing of resources between organizations with similar interests.
Internet:
Another aspect of the cloud computing architecture is the interaction between front end and back end. It enables reliable and secure communication. Both platforms work together to provide seamless cloud computing services to the user.
Various technologies enable the interaction between the two interfaces. For instance,
APIs:
They enable a bridge for ensuring communication between front end and back end technologies.
Gateway Load Balancers:
Act as a channel to divert traffic towards the back end resource that is generated from the front end.
SDKs:
Through SDKs, software developers can integrate front-end and cloud services.
HTTP/HTTPS Protocols:
They ensure secure protocols and help in transmitting data between server and client.
Advantages of Strong Cloud Computing Architecture:
It allows rapid elasticity, which means ensures quick workload adjustments according to the demand.
Improves scalability as it ensures easy scaling of resources.
