Configuring and Managing Multisite and Multi-region Deployments

You can deploy and configure
VMware Cloud Director Object Storage Extension
 within a multisite
VMware Cloud Director
 architecture, and within a multi-region architecture.

Multisite Deployment

A site refers to a
VMware Cloud Director
 instance, which runs within a standalone geolocation. The
VMware Cloud Director
 multisite feature enables a service provider or a tenant of multiple, geographically distributed
VMware Cloud Director
 installations (server groups) to manage and monitor those installations and their organizations as single entities.
By configuring
VMware Cloud Director Object Storage Extension
 within a multisite architecture, you enable tenant users to preview and download objects in remote sites.
With the multisite feature, you achieve high availability and provide a single point of data access for organization users.

Multi-region Deployment

A region refers to an object storage cluster, which runs within a standalone geolocation, with a unique S3 API endpoint. The
VMware Cloud Director Object Storage Extension
 multi-region feature allows the cloud provider to group multiple regions of object storage clusters to a central management plane, on a single
VMware Cloud Director
 site, or across multiple
VMware Cloud Director
 sites.
By grouping multi-region object storage clusters, you can activate S3 regions for specific tenant organizations and tenant users can create buckets within the multi-regions.
The
VMware Cloud Director Object Storage Extension
 add-on supports the multi-region feature on the
Cloudian
 platform. You can create a multi-region environment by creating multiple add-on instances.

Multisite and Multi-region Topologies

You can configure multisite VMware Cloud Director instances with multi-region object storage clusters within the following configurations:
  • Multisite single region topology
  • Single site multi-region topology
  • Multisite multi-region topology

Multisite Single Region Topology

Within a multisite architecture, you can configure
VMware Cloud Director Object Storage Extension
 instances with a standalone virtual data center in each site. The following diagram illustrates the architecture.

You can also configure
VMware Cloud Director Object Storage Extension
 instances in different sites to use a single virtual data center. The following diagram illustrates the architecture.

When you configure the multisite feature, you create a cluster of multiple
VMware Cloud Director Object Storage Extension
 instances to create an availability zone. You can group the
VMware Cloud Director Object Storage Extension
 instances together only in a single region. A region is a collection of compute resources in a geographic area. Regions are isolated and independent of one another.
VMware Cloud Director Object Storage Extension
 does not support multi-region architectures.
You can share the same buckets and objects across tenant organizations within a multisite environment. To share buckets and objects across sites, map all tenant organizations to the same storage group. See Edit Tenant Mapping Configuration.

Multisite Deployment Requirements for
VMware Cloud Director Object Storage Extension

When you configure the multisite feature with
VMware Cloud Director Object Storage Extension
, consider the following requirements.
  • Associate the
    VMware Cloud Director
     sites that you want to use in the multisite environment. For more information, see the
    VMware Cloud Director Service Provider Admin Portal Guide
    .
  • Deploy and configure a
    VMware Cloud Director Object Storage Extension
     instance in each site.
  • You can share your storage platform cluster across sites, or you can deploy and configure all required storage components in each site.
  • Join the storage clusters into a distribution group.
    For
    Cloudian HyperStore
    , set up a storage policy with a multi-DC data distribution group.
    For
    ECS
    , set up replication groups across the virtual data centers.
  • For
    AWS S3
    , use the same AWS payer account to configure
    VMware Cloud Director Object Storage Extension
    . Also, make sure that all
    VMware Cloud Director Object Storage Extension
     sites are configured with an
    AWS S3
     endpoint in the same region.

Single Site Multi-region Topology

When you deploy multi-region object storage clusters, you can deploy one
VMware Cloud Director Object Storage Extension
 server to each object storage cluster. You can connect multiple
VMware Cloud Director Object Storage Extension
 servers to the same
VMware Cloud Director
 site.
With single site multi-region topology, you can deploy multiple instances of the
VMware Cloud Director Object Storage Extension
 solution add-on and configure those instances (deployments) from the
VMware Cloud Director Object Storage Extension
 provider portal.
The following diagram illustrates the architecture.

Multisite Multi-Region Topology

When you deploy multi-region object storage clusters, you can associate multi-region object storage to multisite
VMware Cloud Director
 instances. You can deploy one
VMware Cloud Director Object Storage Extension
 server to each object storage cluster. The
VMware Cloud Director Object Storage Extension
 servers connect to the multisite
VMware Cloud Director Object Storage Extension
. On both the local and remote sites, tenant users can use multi-region object storage with a multisite
VMware Cloud Director
 topology. The following diagram illustrates the architecture.
