Platform and Infrastructure

  • Support for increased vCPUs and memory (cSRX)—Starting in Junos OS Release 23.2R1, Container Firewall (cSRX) supports more virtual CPUs (vCPUs) and memory. With more vCPUs and memory, you can increase throughput, improve the performance and scale up your operations. You can now deploy cSRX in the cloud-native environment.

    [See cSRX Deployment Guide for Bare-Metal Linux Server | cSRX | Juniper Networks].

  • Support for Geneve flow infrastructure with AWS GWLB (vSRX 3.0) —Starting in Junos OS Release 23.2R1, you can integrate vSRX Virtual Firewall (vSRX) 3.0 with Amazon Web Services (AWS) Gateway Load Balancer (GWLB) service that uses the Geneve protocol encapsulation for transparent routing of packets between GWLB and virtual appliances.

    With this feaure, you can use vSRX 3.0 as a transit router or a tunnel endpoint device in various cloud deployments.

    [See Geneve Flow Infrastructure on vSRX 3.0 and AWS Gateway Load Balancing with Geneve.]

  • Support for dynamic update of trusted CA bundle (SRX1500, SRX4100, SRX4200, SRX4600, SRX5400, SRX5600, SRX5800, vSRX 3.0 and NFX350)—Starting in Junos OS Release 23.2R1, we support the dynamic update of default trusted CA certificates. With this feature, you have the latest list of default trusted CA certificates on Junos OS devices. You can easily download, install, and update the certificate bundle periodically.
