2. Who am I
 Cloud Architect with ShapeBlue
 Worked with CloudStack since 2.2.13
 Specialising in deployment of CloudStack
and surrounding infrastructure
 Orange, TomTom, PaddyPower, Ascenty, BSkyB
 I view CloudStack from ‘What can cloud
consumers practically do with it’ point-of-view

What’s New in Apache CloudStack 4.5

4. Summary:
 Bind9 or PowerDNS
 new Network Service Provider called GloboDNS
 new Network Element to manage network domains and VM records
(entries) on an external API
 new Network Resource to communicate with GloboDNS (open
source)
 new API command to add DNS server
 new global option to determine if this provider should override VM
entries on external DNS server
 changes in UI to include GloboDNS in Providers list
Integration with External DNS

5.  Support for LXC ‘hosts’ on RHEL 7.
 NFS, local storage and RBD (Ceph) is supported for Primary storage.
 Beware, unavailable features:
 Console access
 Live migration
 Migration across clusters
 Storage migration
 Snapshots
 Uploading and downloading volumes
 Template creation from ROOT volume
 ISO support for creating VM
Linux Containers

6.  64 bit dom0 removes the limitations of Linux low memory and allows the use of modern
drivers and works better with modern servers
 The move to a 3.10 kernel from kernel.org means the kernel is no longer a completely
custom kernel
 The move to the Xen Project hypervisor 4.4 is the most stable version of the core hypervisor
available.
 Updated OVS to 2.10 virtual switch giving improved network stability when the virtual switch
is under pressure.
 A thread per vif model was introduced to better ensure network hogs didn't impact adjacent
VM performance
 Network datapath optimizations can drive line rate for 10Gbps NICs, and close to line level
with 40Gbps NICs.
 Storage improvement through an update to tapdisk3. Delivering very significant
improvements in aggregate disk throughput

XenServer 6.5 support

7.  Multiple SolidFire SANs supported in a single CS Cloud
 Add Primary Storage based on SF Plug-in via GUI
 Shared-IOPS Plug-in
 Resize Volume (IOPS and Size) - (KVM limited to modifying IOPS only)
Enhanced SolidFire integration

8.  Enables single sign-on and single sign-off across
multiple applications
SAML 2.0 Integration

9.  The Nuage Networks™ Virtualized Services Platform (VSP) is a Software-Defined Networking
solution that virtualizes any datacentre. It deploys the full range of L2-L4 networking services on a
per-tenant or per-application basis using overlay technologies.
 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.
 NuageVsp plugin supports the following network model / service combinations:
 Advanced Isolated networks
 DHCP
 Static NAT
 Source NAT
 Firewall
 VPC network mode:
 DHCP
 Static NAT
 Source NAT
 Network ACL
Nuage Networks Plugin

10.  Adds improved support for XenServer VDI deployments
 GPU-passthrough or vGPU support
 Supports up to 96 vGPU accelerated VMs (XenServer 6.5)
 Requires NVIDIA GRID Kepler 1 and 2 series
vGPU Enhancements

11.  A new plug-in enables automatic VLAN programming on a physical
switch to which baremetal instances are connected. In an Advanced
zone, Baremetal instances gain VLAN isolation
 Baremetal As a Service works in conjunction with a physical switch
either from vendor's SDK or from an in-switch agent for white box
switch.
Advanced Networking in Baremetal

12.  ShapeBlue (Brasil) have tested MySQL 5.6.21 including
in a Master-Master (asynchronous) configuration
 Tested against MySQL 5.6.22
