ZStack Mini inherits the advantages of ZStack's 4S architecture (ie: Simple, Robust, Flexible, Scalable, Smart), and uses the message bus to communicate with the database and various service modules, providing lighter and more flexible cloud host management and all-in-one management , Storage scheduling, network functions, monitoring and auditing and other functions. ZStack Mini also provides standard APIs and SDKs, supports RESTful APIs for resource scheduling management, and facilitates in-depth docking and integration of user services in the future.

ZStack Mini provides an integrated and modular infrastructure of software and hardware, which can significantly reduce the threshold for enterprises to go to the cloud and the burden of later operation and maintenance. Relying on ZStack's mature cloud engine, ZStack Mini has targeted adaptation and improvement for many scenarios, including software and hardware full redundancy design, built-in active-active storage, full visual operation and maintenance interface, fine-grained alarm information, hot pluggable Hardware modules, etc., while accelerating enterprise applications to the cloud, provide an infrastructure environment where stability, availability, and operability are all the best practices.

ZStack Mini adopts the Gemini modular server design and is equipped with x86 standard components, which fully meets the requirements of the application for hardware compatibility; its bottom layer uses real-time synchronized active-active storage, and the synchronization network and heartbeat network are independent redundant lines. Greatly improve high availability efficiency and reduce the risk of data loss; the platform software uses a microservice architecture, based on active-active storage, that data and services can still work normally after any node failure, thereby providing stability for the high availability of upper-layer applications basis.

In the storage design of ZStack Mini, physical hard disks also use traditional RAID technology, but on top of this, logical partitioning technology is used to divide the storage space, and the two nodes independently perform block-level synchronization for each cloud host hard disk. Improve synchronization efficiency while reducing fault domains. Since the shared file system in traditional virtualization is canceled between the cloud host hard disk and the physical hard disk, and the data is directly accessed in the form of block devices, the performance loss is minimal, and the cloud host can give full play to the physical storage performance.

ZStack Mini combines a lightweight ZStack cloud engine with a highly integrated Gemini server to provide efficient management and scheduling of data center computing, storage, and network resources. It supports out-of-the-box use. Users can quickly create cloud hosts, allocate cloud disks, automatically configure cloud host networks, and monitor resource information in real time through ZStack Mini, so as to quickly achieve business online and flexible and convenient business operation and maintenance.
