ZStack is the next-generation, private cloud IaaS software featuring Simple, Strong, Scalable and Smart (4S).

Simple
- Easy installation and deployment: Allows you to download installation packages from our official website. You can install and deploy the cloud from scratch within just 30 minutes.
- Easily-managed cloud: Supports bulk operations of VM instances, such as creating or deleting VM instances in bulk, and provides list displays and sliding window details.
- Simple, practical operations: Provides a thorough User Guide with ample help information, a productive community, and standard APIs.
- Friendly UI: Provides you with a well-designed, friendly user interface to realize powerful features by performing simple operations.
Strong
- Stable, efficient system architecture design: Provides an asynchronous architecture, in-process microservices architecture, lock-free architecture, stateless service architecture, and consistent hashing ring to ensure the system efficiency and stability. Currently, ZStack has achieved various functions. For example, a single management node can manage tens of thousands hosts, and hundreds of thousands of VM instances. A cluster that contains multiple management nodes can use a database and a set of message buses to manage hundreds of thousands of hosts and millions of VM instances, and handle tens of thousands of concurrent APIs.
- High concurrent API requests: Handles high concurrences of API requests. A single ZStack management node can easily handle tens of thousands of concurrent API call requests per second.
- Stringent HA requirements: Provides stringent HA requirements. When a network or management node is unavailable, appliance VM instances can be automatically switched to another management node that is detected as healthy. The management node virtualization helps to achieve the high availability for a single management node. That is, standby management nodes will be dynamically applied within seconds if any management node is disconnected, thus ensuring your business continuity.
Scalable
- Large scale: Manipulates a huge scale of VM instances. Technically, a single management node can manage one to tens of thousands of hosts and hundreds of thousands of VM instances.
- Comprehensive API: Provides a whole set of IaaS APIs. Hence, you can create brand-new, available zones across multiple geographical locations, modify network configurations, and upgrade physical servers.
- Resource allocation based on your needs: Resizes important resources such as VM instances and cloud storages according to your demands. ZStack not only allows you to modify online the CPU, memory, and other resources for a VM instance, but also allows you to dynamically adjust its network bandwidth, disk bandwidth, and other resources for a VM instance.
Smart
- Automatic O&M: Provides all O&M operations that can be managed by ZStack APIs in the ZStack environment. By using the Ansible inventory, ZStack can realize full-automatic deployment and upgrade as well as automatic detection and reconnection. If network jitters happen or hosts restart, each management node can be automatically reconnected to the networks or the hosts. Note that a ZStack scheduler allows you to start or stop VM instances on schedule, and allows you to take VM snapshots on schedule with the round-robin policy.
- Online seamless upgrade: Provides one-click seamless upgrade within 5 minutes. Hence, you only need to upgrade and manipulate management nodes. After the cloud is upgraded successfully and started, the compute node, storage node, and network node will be automatically upgraded as well.
- Intelligent UI interaction: Displays compute resources in real time, thereby empowering you to avoid misoperations.
- Real-time global monitoring: Manages and controls the current resource consumption of the entire cloud. With the real-time monitoring, you can adjust your resources intelligently to save IT software and hardware resources.
