Live Traffic Analysis is supported on segments inside a single SDDC.

VPN Enhancements

  • FIPS 140-2 Validated Cryptographic Modules Refresh:

    • NSX utilizes several FIPS 140-2 cryptographic modules to perform various networking functions in FIPS-compliant mode.  FIPS-validated modules are eventually sunset when the module reaches its expiry date or NIST/CMVP chooses to no longer re-validate certain module(s). When FIPS 140-2 cryptographic modules are sunset, you must replace those modules as necessary to maintain the FIPS validation of their platforms.

    • The FIPS 140-2 cryptographic modules leveraged in release 1.18 (VMware's VPN Crypto Module version 1.0) have been sunset.

    • The current release introduces (VMware's VPN Crypto Module version 2.0) to maintain FIPs 140-2 Validation

  • More information on Validation Status can be found here: Cryptographic Module Validation Program.

  • NAT Support for Policy-Based VPNs on Tier-1 Gateways:

    • VPNs terminated on Tier-1 gateways can now support NAT rules which allows two remote sites that share the same CIDR to use the same VPN.

DHCP UI enhancement

  • The DHCP UI enhancement provides an intuitive workflow and seamless user experience for the Cloud Admin to configure DHCP. The DHCP statistics for Gateway DHCP and Segment DHCP are exposed to help monitor DHCP messages.

Filtering Default CGW prefixes

  • By suppressing more specific route prefixes and instead only advertising aggregated routes for their default CGW workload segments, you can significantly reduce the Transit Connect or Direct Connect, or Connected VPC route table size.

  • The new feature introduces the ability to filter out prefixes of segments connected to the default CGW. When the route filtering feature is enabled on Intranet (DX/TGW) or Services (Connected VPC) endpoints, prefixes behind the default CGW will not be advertised.

Note:

This feature is available for VMware Cloud on AWS GovCloud SDDCs version 1.20 and higher.

Shared Prefix Lists for SDDC Groups

  • This feature is useful in connecting Transit Connect to external VPC and AWS TGW scenarios. Before enabling this feature, you must manually configure return routes for SDDC prefixes on the external VPC and AWS TGW to route traffic to the SDDC group. This manual process can be cumbersome and error-prone over time as SDDC group memberships change and subnets are added or removed from SDDCs.

    SDDC Version 1.16 v11

    VMware HCX 4.3.9 for VMware Cloud on AWS GovCloud

    VMware HCX delivers secure and seamless application mobility and infrastructure hybridity across both on-premises and in the cloud. HCX abstracts the distinct private or public vSphere resources and presents a Service Mesh as an end-to-end entity. HCX Interconnect can then provide high-performance, secure, and optimized multi-site connectivity to achieve infrastructure hybridity and present multiple options for bi-directional virtual machine mobility with technologies that facilitate the modernization of legacy data centers. For more information, see HCX 4.3.9 Release Notes.

What's New 18 July 2022

  • SDDC Version 1.16v11

    • Elastic DRS Storage Scale-up threshold update 

      • Due to enhancements in vSAN, the vSAN Slack Space requirement has been decreased from 30% to 20%. To accommodate this improvement, the Storage Scale-up threshold for all Elastic DRS policies has been increased to 80%. You can now consume up to 79% of vSAN capacity regardless of the Elastic DRS policy.

    • 2-Host Stretched Clusters (1-1) 

      • You can now deploy a 2-host stretched cluster. With a single host in each AZ and a managed witness in the third, the cluster can survive the loss of an entire AZ. This powerful capability enables business-critical applications within VMware Cloud without rearchitecting for AWS availability.  

      • With one host per AZ, vSAN depends on the Dual Site Mirror for resiliency and therefore, it comes with a 99.9% availability guarantee. This can be increased to 99.99% at any time by scaling up to a 6-host cluster.  

      • Elastic DRS storage-only scale-out is enabled by default. If a 2-host stretched cluster is scaled up to a 4-host, the cluster can not be scaled back down. For more information, see the 2-Host release and or Stretched Cluster design considerations. 

    • Stretched Cluster resiliency improvements

      • Elastic DRS has been improved to increase the resiliency of any Stretched Cluster. This enhancement is provided free of charge and works in conjunction with the existing Auto-Remediation capabilities found in Auto-Scaler. For more information, see Scaling Multiple Availability Zone Clusters. 

      • The VMware Cloud service will automatically Scale-Out any Stretched Cluster on AZ failure. With this latest enhancement, the cluster will automatically Scale-In as soon as the failed AZ has been restored and the burst capacity is no longer needed.  

      • If an instance fails on a Stretched Cluster and Auto-Remediation is unable to recover or replace the host, the service will add the instance to the other AZ until a new host can be recovered in the original AZ. This capability is added free of charge and will attempt to maintain the Compute resources in the event of a partial AZ failure by adding non-billable hosts to the surviving AZ until the cluster has returned to its original host count. This functionality is dependent on free capacity and therefore carries no guarantee.

    • Networking and Security - Operational Improvements

      • You can view network traffic stats per external interface to the SDDC. The Global Configuration tab provides user visibility in terms of bytes/packets received and transmitted per uplink. You can also control interface settings on the Global Configuration tab.

    • vSphere Distributed Switch (VDS)

      • The vSphere Distributed Switch (VDS) enables you to manage NSX network segments as vCenter DVPG objects. New deployments in 1.16 will use VDS. Existing deployments will be converted to VDS prior to 1.18 upgrade. The vSphere Web Services API Opaque Network objects will be converted to NSX DistributedVirtualPortGroup (DVPG) objects. The corresponding API parameters/return values are changing, therefore users need to update applications that are using these API calls. vSphere Opaque Network objects will not be supported beyond 1.16. For more details, including the latest VMware and partner application versions that are compatible with VDS, see KB 82487.

    • Compute Policy Scale Increase

      • The limit for VM-VM anti-affinity compute policies has been increased to 1500 (total of all compute policies combined). The limit for all other compute policies remains at 100. Using the card view is recommended when working with a large number of policies in the UI. See the VMware Configuration Maximums page for limit details.

What's New 06 January 2022

  • SDDC Version 1.14v7

    • Regional Expansion to AWS GovCloud US-East region

      Since the launch of VMware Cloud on AWS GovCloud (US), the hybrid cloud service has been helping Federal, state and local government agencies in their digital transformation initiatives. VMware now announces the regional expansion of VMware Cloud on AWS GovCloud (US) service to the AWS GovCloud US-East region. This will bring the availability of the service to both AWS GovCloud regions – GovCloud (US-West) and GovCloud (US-East). This gives US public sector customers additional geographic choice and disaster recovery options for sensitive data and workloads while meeting US government security and compliance requirements. 

    • Support for 2-host i3en.metal

      Reduce your steady state and recovery infrastructure costs by using a 2-host i3en.metal SDDCs.

    • 2-Host Stretched Clusters (1-1)

      You can now deploy a 2-host stretched cluster. With a single host in each AZ and a managed witness in the third, the cluster can survive the loss of an entire AZ. This powerful capability enables business-critical applications within VMware Cloud without rearchitecting for AWS Availability.

What's New 05 October 2021

  • SDDC Version 1.14v6

    • Performance Optimizations for Erasure Coding for bursty writes

      In version 1.14, you can view an improved performance and CPU efficiency of RAID 5/6. This enables the space efficiency of erasure coding while enhancing application performance and reducing CPU cost per I/O, particularly for bursty writes. Improved additional buffer tier performance.

    • Stretched Cluster/ Multi-AZ Improvements: vSAN DRS awareness

      VMware Cloud on AWS version 1.14 introduces integration with data placement and DRS so that after a recovered failure condition, DRS will keep the VM state at the same site until data is fully re-synchronized, which ensures all read operations not to traverse the Inter Site Link (ISL). Once the data is fully re-synchronized, DRS moves the VM state to the required site with DRS rules accordingly.  The improvement can dramatically reduce unnecessary read operations occurring across the ISL, and free up ISL resources to continue with its efforts to complete any re-synchronizations post-site recovery.

    • Automatic adjustment of vSAN policy for improved data availability

      The automatic adjustment of vSAN policy for improved data availability feature will automatically assign the default policy for your VMs to ensure that your workloads are SLA compliant. You can deploy your cluster, and based on the number of hosts, a policy will be automatically assigned. If a host limit is crossed which requires a different policy, then the policy is automatically changed so that your clusters remain SLA compliant. If you want to set the policies yourselves, you can override this function.

      • The policies settings which will be applied by automatic adjustment of vSAN policy for improved data availability are:

        • Standard Cluster:

          • =< 5 hosts: Failure to tolerate 1 - RAID-1

          • >= 6 hosts: Failure to tolerate 2 - RAID-6

        • Stretched Cluster:

          • Dual Site Mirroring, Failure to tolerate 1 - RAID-1

              Note: This feature is enabled for SDDC versions 1.10 and higher.

What's New 11 March 2021

  • SDDC Version 1.12v5
