All kinds of businesses, let it be small scale large-scale, are shifting to cloud-based services. The adoption of both public and private clouds have increased in the past few years. The reason behind this shift is lower operating costs and increased flexibility. Cloud computing technology utilizes remote servers to store, manage, and access data on the internet rather than have a local infrastructure.
Why Cloud Computing?
In cloud computing, we can develop new applications and services, store and backup our data, host blogs, and websites, analyze the data, and stream audio and video. There is no need for large and complex cloud computing infrastructure as the storage and processing are done on remote servers called cloud servers.
As the software platform and databases are hosted remotely, the individual computers are free from the storage and computing tasks. Cloud computing offers a wide range of benefits, including high efficiency, cost reduction, data security, scalability, mobility, disaster recovery, and complete control over the data.
The cloud computing architecture consists of two parts front end and the back end, the front end part is the one that is used by the user, and the back end part is managed by the host. Both ends are connected to each other via the internet. The frontend includes applications and interfaces that help the user access the cloud services. The company offering cloud services manages the back end and has data storage facilities, virtual machines, security systems, and servers.
Here is a List of Components of Cloud Computing Architecture-
1. Client Infrastructure
The client infrastructure component is the part of the frontend which provides a graphic user interface for the user to interact with the cloud.
An application is any platform like an app or software offered by a company by which the clients access the cloud.
A cloud service manages the kind of service that a client needs to use according to his requirement. There are three types of services in cloud computing.
-Software as a Service (SaaS): SaaS-based services are known as cloud application services. They run directly through a web browser eliminating the need for any download or installation of the applications—for example, slack Hubspot and Google apps.
-Platform as a Service (PaaS): PaaS services are similar to SaaS. However, PaaS services provide a platform for users to build, edit, and launch the software. For example, Magneto commerce cloud and Windows Azure.
-Infrastructure as a service (IaaS): IaaS manages application data runtime environments and middleware. It provides virtual services that eliminate the need for physical computing resources such as RAM, CPU, and data centres. In IaaS, the companies run virtual servers, networks, and storage on the cloud on a paid basis. For example, Google Compute Engine (GCE), Amazon Elastic Compute Cloud, and Amazon Web Services (AWS).
4. Runtime Cloud
The runtime cloud provides the execution and runtime environment to the virtual machines.
The storage component of cloud computing provides the storage capacity in the cloud for storing and managing data. In cloud storage, the data can be accessible to multiple clients simultaneously. Cloud storage is generally in the form of three basic configurations: public cloud, private cloud, and hybrid cloud.
The infrastructure provides services on the host level, application level, and network level. It includes the software and hardware components such as the storage network devices server and any other storage resource required to support the cloud computing model.
Management is used for managing the components such as storage services, applications, runtime cloud infrastructure, and security issues in the backend and for establishing coordination.
Security is the backend component of cloud computing, which insurance the security of data in the cloud. The security system in the cloud includes a broad set of policies, technologies, applications, and controls that are used for protecting the IP’s, data, applications, infrastructure, and the services offered in cloud computing.
Internet is the medium using which the frontend and backend components communicate and interact with each other.
By using a cloud-based solution, companies can work on lower budgets and eliminate on-premises infrastructure. Cloud computing is being extensively adopted due to its infinite advantages that positively impact creation, innovation, collaboration, security, ease of use, and sales.
