ECS Bare Metal Instance vs. IaaS

This article compares an ECS Bare Metal Instance and pure IaaS.

By Shantanu Kaushik

Today's world utilizes immense computing and cloud power. The artisans of cloud computing would never have thought of evolution within their concept to the levels we have witnessed. The growth is exponential, and the future trends suggest more growth and substantial space for another paradigm shift.

The core computing scenarios, tools, and practices have evolved. Within DevOps :arrow_right: DevSecOps :arrow_right: DataOps :arrow_right: AIOps :arrow_right: NoOps, we have witnessed a significant development of solutions knitted around cloud computing. Hybrid cloud introduced the concepts of workload sharing and hybridization of computing resources for better productivity. Similarly, multi-cloud brought along the approach to leverage distributed resources for better computing scenarios and redundancies.

Infrastructure as a Service

This is how the cloud evolved, but we have to start from the beginning. The very basic concept of the cloud caters to a big chunk of organizations that want to implement their business scenarios using the cloud. These organizations use Infrastructure as a Service (IaaS) to set up their digital presence and use the raw computing power presented to them using a virtualized server resource with high elasticity, reliability, and flexibility.

IaaS extends through automation and provisions virtualized resources, such as computing power, storage, and network resources. As a result, it can work through multiple scenarios. Since the service is managed by the cloud provider, there is little time spent on the maintenance operations required by the hardware infrastructure in a traditional setup. This enables the organization to manage their operating system, runtime environment, middleware, data, and applications.

The baseline is essential; the organization has complete control over an IaaS resource and can use it as required. The processing power of this service can be adjusted on the fly using horizontal and vertical Auto Scaling.

ECS Bare Metal Instance

Since we already have a dedicated article explaining what an ECS Bare Metal Instance is, the information below is only a brief overview.

Alibaba Cloud developed virtualization 2.0 technologies to enable hypervisor-based dedicated server instances for organizations looking to implement using a dedicated hardware resource. As a result, ECS Bare Metal Instance was created. It incorporates the elasticity of a virtual server and the resource orchestration and root-level access scenarios of a dedicated physical server.

Differentiating an ECS Bare Metal Instance and IaaS

Alibaba Cloud Elastic Compute Service (ECS) is a classic example of an Infrastructure as a Service (IaaS) based solution. ECS is a managed service that provides a shared virtual server structure and works with orchestrated services, such as network, storage, security. ECS instances provide the user with the core infrastructure to bring their operating system, data, middleware, and runtime.

ECS Bare Metal Instance is also a fully-managed service that provides an infrastructure for large-scale organizations that do not want to implement using a shared virtual resource. Instead, they require a dedicated resource to implement their custom solution and applications.

While both IaaS and ECS Bare Metal Instance provide the backend infrastructure, one is based on the shared model, and the other one is a dedicated server. An ECS Bare Metal instance provides all the features of IaaS and offers a single tenant or dedicated server.

Let’s take a look at the comparison chart below:


Alibaba Cloud ECS Bare Metal Instance provides a rich feature set by including the functionality of a physical resource and the elasticity of a fully-managed IaaS resource. Operations and Maintenance (O&M) is an added advantage since high resources are required for O&M operations in other scenarios.

The concepts of Bare Metal and Alibaba Cloud ECS Bare Metal Instance are not exactly alike, but they share the same core practice of offering a dedicated resource. The solution from Alibaba Cloud provides a hybrid approach to incorporate the best of both worlds. However, the elasticity of operations that Alibaba Cloud introduced with their ECS Bare Metal Instance doesn’t change the single tenant approach and orchestration of resources.

Virtual Servers are the most common model of operation in a multi-tenant approach with the cloud. It provides high-performance computing with more reliability. The unique capacity to auto scale resources is a niche option for virtual servers.

Alibaba Cloud has bridged the gap between physical and virtual servers with a solution that provides an environment with a feature set that is useful for enterprises that want to deploy their solutions to capture different industries and businesses.

Wrapping Up

Alibaba Cloud has worked with the open-source community and conducted in-house research to understand and develop solutions that revolutionize the industry practices. E-HPC, ECS Bare Metal Instance, and the complete line-up of products and services provide a seamless experience. There are solutions to bridge any performance and stability gaps that enterprises might face while implementing their custom solutions.
