CHAPTER 1

What’s New in 4.5

Version 4.5.1 includes more than 200 bug ﬁxes from previous release, the following new features and improvements.

1.1 NuageVsp Network Plugin

The Nuage NetworksTM Virtualized Services Platform (VSP) is a Software-Deﬁned Networking (SDN) solution that

virtualizes any datacenter (DC) network infrastructure and automatically establishes connectivity between compute

resources upon their creation.

NuageVsp networking plugin bring the Nuage VSP network virtualization technology to CloudStack. All the network

isolation and routing is handled by the Nuage SDN solution. Routing of the packets happen at hypervisor itself. Virtual

Router is not used for routing the packets and is spawned only for Password reset functionality. The Nuage solution

also helps signiﬁcantly improve the agility and scale of a CloudStack deployment as compared to a Virtual Router

based deployment.

Supported hypervisors: XenServer, VMware

1.2 Bind integration with Globo DNSAPI

GloboDNS provide API to Bind DNS server used to centralized DNS server outside of CloudStack networks. When

deploying Advanced Networks, Virtual Routers are used to isolate networks and provide DNS service for all ma-

chines inside each network. This approach imposes a challenge when instances need to translate names that belong to

instances from another network.

Supported hypervisors: Any

1.3 SAML 2.0 Plugin

SAML 2.0 Plugin provide integration of CloudStack to existing authentication mechanism. This provide Single Sign

On (SSO) and Single Log Out (SLO) to work on CloudStack UI and clients. SAML (Security Assertion Markup

Language) 2.0 is an old, stable and widely used XML based authentication and authorization protocol supported by

Salesforce, Google Apps and other public and private companies and the aim is to integrate the SSO SAML support in

CloudStack. The current implementation is experimental, will change in future and should be avoided in prouduction.

Supported hypervisors: N/A
