Cloud Container Instance (CCI)

Cloud Container Instance (CCI) on the Open Telekom Cloud is a serverless container engine that provides a hassle-free way to run containerized applications using Kubernetes without having to create and manage server clusters. As a result, the operational overhead is reduced, and users can concentrate on building and operating their applications, ultimately driving business growth and success.

Typically, running containerized workloads on Kubernetes necessitates the initial creation of a Kubernetes server cluster. However, under the serverless model, the entire container deployment process is simplified. To deploy and operate applications, users are only required to specify their resource needs, such as the necessary CPU cores and memory space, while the cloud takes care of the maintenance and management of the underlying infrastructure and server clusters.

Containerized applications can be seamlessly deployed in a few steps by using console, kubectl, or Kubernetes APIs without the complexities of needing to create and manage Kubernetes cluster.

Resources consumed by workloads are billed on-demand and calculated in seconds. This granular pay-as-you-go billing approach ensures that you only pay for the exact resources you use, reducing unnecessary costs and optimizing budget allocation.

CCI leverages Kata containers and its virtualization acceleration technology to achieve virtual machine (VM) level isolation without compromising startup speed, enhancing the overall container experience for users. Pods start up within seconds to enable businesses to swiftly adapt to services changes and handle any traffic bursts.

CCI uses open-source technology and is compatible with native Kubernetes, Kata container and Docker APIs, and supports Docker images, allowing users to use familiar tools and workflows.

• Thanks to the serverless framework employed by CCI, users can deploy and operate Kubernetes workloads without creating and managing server clusters.
• Various interfaces (console, kubectl or Kubernetes APIs) can be used for the operation and maintenance of workloads.
• Billing-per-second offers a flexible and efficient way to control consumed IT resources and budgets.

Various network access modes and load balancing at both Layer 4 and Layer 7 are available to meet scenario-specific needs.

In addition, CCI interconnects with Elastic Volume Service (EVS), SFS Turbo and Object Storage Services (OBS) to store user data.

Automatic elastic scaling can be accomplished within a mere second by using user-defined scaling policies. By using a flexible combination of these polices, traffic surge during peak hours can be easily dealt with.

The resources consumed by containers are monitored, including the CPU usage, memory usage, GPU compute usage, and GPU memory usage, from which you can determine the running status of the containers in real time.
