    Hosting and Distribution of Images Worldwide

    When an enterprise-class container customer expands business throughout the country or to multiple regions worldwide, the customer needs to pull images from the nearest region. This not only improves the pulling speed to ensure fast business deployment, but also enables data transmission through private networks in the same region to reduce public network bandwidth costs.
    TCR supports the use of shared instances and exclusive Enterprise Edition instances in multiple regions worldwide. In particular, an Enterprise Edition instance supports rule-based automatic synchronization among instances, which can quickly synchronize newly pushed container images to instances in other regions. This not only allows the user to pull images from the nearest region, but also reduces the OPS costs and risks incurred by manual push of images to several regions.

    Large-Scale Image Distribution

    As the business scale of the enterprise user's container is continuously increasing or the user migrates their existing large-scale business to a container, the number of nodes in the container will increase as well, and some clusters can even have over one thousand nodes each. In addition, with the emergence of business scenarios such as deep learning and DNA computing, the container cluster starts to support a large amount of offline computing load, and the container images for these business scenarios are often several gigabytes in size.
    To enable a large number of clusters to concurrently pull images of several gigabytes, the TCR Enterprise Edition uses the service backend that supports containerization deployment and the exclusive storage backend (COS bucket) to reliably cope with highly concurrent pulling requests from the Docker client. TCR also supports P2P image distribution. After enabling this feature in the Tencent Kubernetes Engine (TKE) service, you can use the P2P accelerated distribution technology to accelerate image pulling and ensure fast business deployment.

    Containerized Continuous Deployment

    After an enterprise deploys large-scale containers in the cloud, traditional business application development and deployment processes face challenges and the enterprise turns to the cloud native DevOps solution. TCR is closely integrated with TKE and CODING DevOps to deliver the cloud native DevOps solution. The enterprise only needs to configure Continuous Integration/Continuous Delivery (CI/CD) workflows on the CODING DevOps platform. After that, source code updates automatically trigger image building and security scans. Then, the images are synchronized to instances in multiple production regions worldwide. Finally, the business applications in the container cluster are automatically updated. If the enterprise already has complete CI/CD workflows, TCR also allows the enterprise to configure custom triggers to interconnect with the enterprise's own CD system and smoothly incorporate TCR in the existing business development process.
