VMware ECS

VMware ECS

What Is VMware Elastic Server?

A VMware Elastic Cloud Server (ECS) is a scalable computing server provided by VMware vCenter. By interconnecting VMware Service with VMware vCenter, VMware ECSs can be centrally managed on ManageOne.

Concepts

VMware IMS

A VMware image is an Elastic Cloud Server (ECS) template that contains software and mandatory configurations. Specifically, an image contains an OS and may also contain proprietary software and application software, such as database software. You can use a VMware image to create a VMware ECS or convert a VMware ECS to a VMware image.

Regions and AZs on VMware Service

A region refers to the physical location of an ECS. Creating ECSs in different regions can better suit user requirements. For example, applications can be designed to meet user requirements in specific regions or comply with local laws or regulations. ECS pricing also changes based on region.

Each region contains many availability zones (AZs) where power and networks are physically isolated. AZs in the same region can communicate with each other over the intranet. Each AZ provides cost-effective and low-latency network connections that are unaffected by any possible faults in other AZs. Therefore, deploying ECSs in separate AZs protects your applications against faults that may occur in a specific location.

Data Storage of VMware Service

Data storage of VMware Service is a virtualized storage technology that implements dynamic storage services by centrally managing and allocating physical storage resources.

Advantages

VMware ECS has the following advantages:

  • VMware ECSs are more cost-effective than traditional servers.
  • VMware ECSs help users better manage computing resources.

Application Scenarios

VMware ECSs are virtual computing facilities that can be scaled up or down based on your requirements. You can rent computing and storage resources based on your needs at a low cost. This greatly reduces your hardware costs. The unified management platform is provided to reduce maintenance and management difficulties. You only need to focus on services, as shown in Figure 40-2.

  • Applications

    Web servers, R&D and testing environments for developers, and small-scale databases

  • Characteristics

    General-purpose VMware ECSs are suitable for applications that have no special requirements on vCPU performance, memory, disk capacity, or bandwidth, but have high requirements on security and reliability. They feature low initial investment and maintenance costs.

  • Application scenarios

    Enterprise official website deployment, enterprise office environment setup, and enterprise R&D and testing activities

Component Type

Component Name

Details

Cloud service console

VMware ECS UI

Provides the VMware ECS console.

Cloud service

Compute

Processes the operation request of the VMware ECS console.

Scheduler

Sorts and filters VMware ECS operation requests.

CoreTask

Processes VMware ECS operation tasks.

Common components

LVS

Provides level-1 load balancing.

Nginx

Provides level-2 load balancing.

DNS/NTP

Provides domain name parsing and time synchronization capabilities.

API Gateway

Allows a third-party application to call VMware ECS APIs.

Resource pool

vCenter

Provides a scalable platform that lays a foundation for virtualization management. VMware Service takes over resources from the vCenter resource pool to ManageOne.

Management domain

IAM

Supports identity authentication and access control for VMware ECS.

Metering

Provides the function of metering and charging resources.

Service OM

N/A

Workflow

Figure 40-4 shows the VMware ECS workflow.

Figure 40-4 VMware ECS workflow

  1. VDC administrators or VDC operators apply for VMware ECSs from the ManageOne operation plane. VMware Service delivers the operation requests to Compute for processing.
  2. Scheduler filters and sorts the processed operation requests.
  3. CoreTask processes tasks in sequence.
  4. API Gateway distributes the requests to vCenter systems.

Related Services

Figure 40-5 shows services related to VMware ECS.

  • VMware EVS

    VMware EVS disks can be attached to VMware ECSs and capacities of VMware EVS disks can be expanded at any time.

  • VMware IMS

    You can create VMware ECSs using images provided by VMware IMS to improve the VMware ECS deployment efficiency.

  • VMware Snapshot

    VMware Snapshot allows you to back up VMware ECSs and use the backup data to restore the VMware ECSs. This avoids irreversible loss caused by misoperations.

Accessing and Using VMware ECS

FusionCloud provides a web-based service management platform, which users can access with the ManageOne operation plane or API.

  • ManageOne operation plane

    Users can use the ManageOne operation plane to access the cloud service. If you are a VDC administrator, VDC operator, or have the operation rights for the cloud service, you can directly log in to the ManageOne operation plane and choose this cloud service on the Product List or Console menu.

  • API

    If you want to integrate the service into a third-party system for secondary development, you can access the service using API. For details, see the API reference of the cloud service in FusionCloud 6.3.1.1 API Reference.
