Citrix NetScaler VPX has been updated to version 12.1.

Virtual servers with multiple IP addresses

You can now create a single load-balancing virtual server with multiple non-consecutive/consecutive VIP IPv4 and IPv6 addresses. Each VIP address bound to a virtual server is treated as an individual virtual server.

For more information about this feature, see the Citrix article Multiple IP virtual servers .


The following updates have been applied for SSL connections:

  • Removal of weak ciphers from the DEFAULT_BACKEND cipher group.
  • Support for ECDHE ciphers on the front end of Thales nShield® external HSM
  • Support for ECDHE ciphers on the front end of SafeNet network external HSM
  • Removal of SSLv2: The NetScaler VPX appliance does not support SSLv2 from release 12.1.

Service Groups Support for GSLB

You can now configure IP address-based service groups, domain-name-based service groups, or domain-name-based autoscale service groups for GSLB. You can also manage a group of services as easily as a single service, and bind a service group to a virtual server, as well as add services to the group.

For more information about GSLB service groups, see the Citrix article Configuring a GSLB service group.

Optimize observability with IBM Cloud Logs to help improve infrastructure and app performance

5 min read - There is a dilemma facing infrastructure and app performance—as workloads generate an expanding amount of observability data, it puts increased pressure on collection tool abilities to process it all. The resulting data stress becomes expensive to manage and makes it harder to obtain actionable insights from the data itself, making it harder to have fast, effective, and cost-efficient performance management. A recent IDC study found that 57% of large enterprises are either collecting too much or too little observability data.…
