What Is Flexus X Instance?

Flexus X Instance (FlexusX) is a next-generation flexible cloud server service designed for small- and medium-sized enterprises (SMEs) and developers. FlexusX provides functions similar to what ECS provides. In addition, with FlexusX, you can flexibly configure vCPU to memory ratios to match your specific needs and change server specifications without service interruptions.

Application Scenarios

  • E-commerce livestreaming: building e-commerce transaction platforms on FlexusX instances to handle spikes and lulls in the e-commerce market
  • Enterprise website setup: helping enterprises set up platforms such as blogs, forums, and websites to communicate, share, and spread information
  • Individual development and testing: building development and testing environment on FlexusX instances easily and cost-effectively
  • Game servers: creating game servers with robust computing power to support 1,000+ players online at the same time, smooth scaling to handle the sudden increase of online players, and strong network acceleration capability to improve user experience.

Advantages

  • A variety of public images and versions are provided for you to choose from.
  • Service changes can be intelligently detected and specifications can be dynamically adjusted, allowing for a higher workload range.
  • vCPU and memory specifications can be flexibly customized.
  • FlexusX instances support the flexible pay-per-user billing mode and provide intelligent recommendations for instance specifications.

Billing Modes

FlexusX instances support the yearly/monthly and pay-per-use billing modes to meet your requirements in different scenarios. You can change the billing mode from yearly/monthly to pay-per-use, and vice versa.

Resource Configuration

FlexusX instances provide resources covering compute (vCPUs/memory and images), networking (VPCs and EIPs), storage (EVS disks), security (HSS), and Cloud Eye. You can flexibly configure resources based on service requirements.

Differences Among FlexusX, FlexusL, and ECS

  • A FlexusL instance is a package of resources that include cloud servers, EVS disks, EIPs, CBR vaults, and HSS. Resources in the package are created and managed together. FlexusL instances provide various featured application images to help you quickly set up service environments. FlexusL instances are easy to use and friendly to beginners in cloud computing.

    Both FlexusL and FlexusX instances are lightweight cloud servers. FlexusL instances are sold and managed as packages. FlexusX instances provide more flexible specifications and functions and have fewer constraints.

  • An ECS instance is a server that supports high-load scenarios. It provides multiple billing modes, flavor types, image types, and disk types. You can customize ECS configurations for different service scenarios.

    FlexusX provides functions similar to what ECS provides. It is a simplified version of ECS. FlexusX simplifies the purchase process of cloud servers. It supports one-stop purchase for compute, disk, and network resources, as well as Cloud Eye and HSS cloud services. It helps you configure cloud servers easily and efficiently. In addition, with FlexusX, you can flexibly configure vCPU to memory ratios to match your specific needs and change specifications without service interruptions.

  • FlexusX instances use the same underlying hardware resources as ECS instances and deliver the same compute performance as ECS instances with the same specifications.
  • For high-load applications, you are advised to use ECS for more stable performance.

For details about the differences among them, see Table 1.
