Public, Private, and Hybrid Cloud on Alibaba Cloud

By Shantanu Kaushik

Cloud computing is a resource that is made possible with the advancements in networking and compute technology in the past decade. Cloud computing delivers superior and more reliable computing power by provisioning resources like servers, database, storage, applications, and infrastructure for specific tasks and practice.

One of the most prominent features of cloud computing is its scalability, helping businesses churn out more computing power as and when needed. Alibaba Cloud provides such capability to customers through the Elastic Compute Service (ECS). ECS lets you provision more or reduce resources based on real-time demand as presented. Features like Auto scaling and Server Load Balancer (SLB) helps businesses automate this process, and lets them focus on system design while keeping their applications at a higher level of availability.

Cloud Backup and Recovery is another popular feature that businesses take advantage of when using cloud-based solutions. Creating data backups is a key step for businesses to preserve the integrity of customer and business data. Alibaba Cloud offers virtually unlimited data storage capability through its Object Storage Service (OSS) and provides an industry leading solution for backup and disaster recovery practices.

Perhaps the biggest advantage of using a cloud-based solution is that there is no need for physical resource allocation, helping businesses be more agile and keep operating costs at a minimum. In this blog, we’ll be talking about the differences between public, private, and hybrid cloud, and discuss how you can implement them with Alibaba Cloud.

The Cloud Story | Security and Accessibility

When following virtualization practices, creating a private cloud on a public cloud can provide a highly-secure environment. The provisioned resources are Virtual Machines (VMs) that have their own allocated resources. These resources can be isolated with each other to form a more secure and controlled environment.

Public Cloud

As this infrastructure is based on a virtual environment, there is no need for the user to purchase and install any physical servers to get connected. All one needs to do is to purchase an online resource and start working. This makes up for a highly cost-effective service when compared to the traditional model.

Operations and Maintenance (O&M) is a common concern when it comes to managing resources in a private cloud. But on a public cloud, the user is free from any O&M because the physical side of the service has nothing to do with the user. In addition, public clouds typically support a pay-as-you-go pricing model, which lets you pay only for what you use.

Security| Public Cloud

Public Cloud is the virtual image of the cloud provider that you are leasing the services from. In case of Alibaba Cloud, these cloud services are highly secure and scalable. When it comes to data and resource vulnerabilities, public cloud infrastructure is a secure resource, however, configuration, data management, authentication and encryption are handled by the user or administrator.

Who Should Use Public Cloud?

Hybrid Cloud | Alibaba Cloud

Hybrid cloud is a mixture of both, giving you the benefits from public and private clouds. It addresses the expectations and challenges of Public and Private cloud, and offers solutions accordingly. It provides a certain level of flexibility that public and private cloud platforms lacked.

Hybrid cloud architecture provides workload portability and management across public and private cloud. With the introduction of technological innovation such as Artificial Intelligence (AI) and Internet of Things (IoT), a desperate need of intelligent cloud solutions is on a rise. These solutions can be made possible by using a Hybrid Cloud architecture that delivers a dynamic solution.

A typical Hybrid Cloud architecture includes:


While working with core-competencies, all the products that I used by the Alibaba Cloud platform have worked in-sync with each other and presents a far greater usability scenario for me. Multi-region-support for services, and solution driven design has had a far greater influence on me as a user to further trust the products and services by Alibaba Cloud.
