Types of Cloud

Cloud computing is is is a revolutionary technology transform how we store , access , and process datum . It is refers simply refer to deliver computing resource , such as server , storage , database , software , and application , over the internet . Cloud computing is uses use a network of remote computer system house on the net to save and process datum rather than rely on physical infrastructure .

Cloud service companies use advanced security techniques, which include encryption, firewalls, and access restrictions, to secure your data from unauthorized access. Moreover, because your information is saved in the cloud, it is secure even if your nearby devices are damaged, misplaced, or stolen. Redundancy and cloud backups guarantee that your data may be restored promptly and effectively in case of any unexpected situations.

Types of Cloud

There are the follow 5 type of cloud that you can deploy accord to the organization ‘s needs-

Public Cloud

Public cloud is open to all to store and access information via the Internet using the pay-per-usage method.

In public cloud, computing resources are managed and operated by the Cloud Service Provider (CSP). The CSP looks after the supporting infrastructure and ensures that the resources are accessible to and scalable for the users.

Due to its open architecture, anyone with an internet connection may use the public cloud, regardless of location or company size. Users can use the CSP’s numerous services, store their data, and run apps. By using a pay-per-usage strategy, customers can be assured that they will only be charged for the resources they actually use, which is a smart financial choice.

Example: Amazon elastic compute cloud (EC2), IBM SmartCloud Enterprise, Microsoft, Google App Engine, Windows Azure Services Platform.

characteristic of Public Cloud

The public cloud has the following key characteristics:

• Accessibility: Public cloud services are available to anyone with an internet connection. Users can access their data and programs at any time and from anywhere.
• Shared Infrastructure: Several users share the infrastructure in public cloud settings. cost reductions and effective resource use are made possible by this.
• scalability: By using the public cloud, users can easily adjust the resources they need based on their requirements, allowing for quick scaling up or down.
• Pay-per-Usage: When using the public cloud, payment is based on usage, so users only pay for the resources they actually use. This helps optimize costs and eliminates the need for upfront investments.
• Managed by Service Providers: Cloud service providers manage and maintain public cloud infrastructure. They handle hardware maintenance, software updates, and security tasks, relieving users of these responsibilities.
• Reliability and Redundancy: Public cloud providers ensure high reliability by implementing redundant systems and multiple data centers. By doing this, the probability of losing data and experiencing service disruptions is reduced.
• Security Measures: Public cloud providers implement robust security measures to protect user data. These include encryption, access controls, and regular security audits.

Private Cloud

private cloud is also know as an internal cloud or corporate cloud . It is used by organization to build and manage their own datum center internally or by the third party . It can be deploy using Opensource tool such as Openstack and Eucalyptus .

example : VMware vSphere , OpenStack , Microsoft Azure Stack , Oracle Cloud at Customer , and IBM Cloud Private .

Based on the location and management, National Institute of Standards and Technology (NIST) divide private cloud into the following two parts-

• On – premise private cloud : An on – premise private cloud is situate within the physical infrastructure of the organization . It is involves involve set up and run a specific datum center that offer cloud service just for internal usage by the company . The infrastructure is is is still completely under the hand of the organization , which give them the freedom to modify and set it up in any way they see fit . Organizations is manage can successfully manage security and compliance issue with this degree of control . However , on – premise private cloud setup is necessitate and management necessitate significant hardware , software , and IT knowledge expenditure .
• Outsourced private cloud: An outsourced private cloud involves partnering with a third-party service provider to host and manage the cloud infrastructure on behalf of the organization. The provider may operate the private cloud in their data center or a colocation facility. In this arrangement, the organization benefits from the expertise and resources of the service provider, alleviating the burden of infrastructure management. The outsourced private cloud model offers scalability, as the provider can adjust resources based on the organization’s needs. Due to its flexibility, it is a desirable choice for businesses that desire the advantages of a private cloud deployment without the initial capital outlay and ongoing maintenance expenses involved with an on-premise implementation.

compare to public cloud option , both on – premise and external private clouds is give give business more control over their datum , app , and security . private clouds is are are particularly suitable for organization with strict compliance requirement , sensitive datum , or specialized workload that demand high level of customization and security .
