OpenStack history of computing environment

Oname.com VPS(Diablo) • Service XaaS model:

– VPS (KVM, libvirt)• Network:

– 1Gbps• Network model:

– Flat-VLAN (Nova Network), without floting IP(no L3)

– IPv4 only• Public API

– None (only web-panel)• Glance

– Public image only.

OpenStack service: Onamae.com VPS(Diablo)

ConoHa(Grizzly)• Service XaaS model:

– VPS + Private networks (KVM + ovs)• Network model:

– Flat-VLAN + Quantam ovs-GRE overlay

– IPv6/IPv4 dualstack• Network:

– 10GE wired(10GBase-T)

• Public API: None (only web)• Glance

– Only Public image• Cinder: None• ObjectStorage

– Swift (After Havana)

OpenStack service: ConoHa(Grizzly, 2013/07)

Grizzly• Quantam Network:

– It was using the initial version of the Open vSwitch full mesh GRE-vlan overlay network with LinuxBridge Hybrid

ButWhen the scale becomes large, Localization occurs to a specific node of the communication of the GRE-mesh-tunnel(with under cloud network(L2) problems)(Broadcast storm?)

OpenStack service: ConoHa(Grizzly)

• Service XaaS model:– KVM compute + Private VLAN networks + Cinder + Swift

• Network:– 10Gbps wired(10GBase SFP+)

• Network model: – IPv4 Flat-VLAN + Neutron LinuxBridge(not ML2) + Cisco Nexsu L2 sw/port

driver– Brocade ADX L4-LBaaS original driver

• Public API– Provided the public API

• Ceilometer (Billing)• Glance : Provided(GlusterFS)• Cinder : HP 3PAR(Active-Active Multipath original) + NetApp• ObjectStorage : Swift cluster • Bare-Metal Compute

– Modifiyed cobbler bare-metal deploy driver – Cisco Nexsus switch bare-metal networking driver (L2 tenant NW)

Cisco Nexsus L2 sw/Port manage driver(self made)• L2 resource is limited / SW CPU

– MAC ADDRESS– VLAN per Network– VLAN per Port

Allowed VLAN to trunked port is allowed only VLAN to be used in LinuxBridge in VM/Baremetal Compute node.

OpenStack API

Cinder APICeilometer API

Endpoint L7:reverse proxy

Swift Proxy

public API: step 1, step 2)

step 1) LVS-DSR (L4) is received https(tcp/443) packet, then forward api-reverse-proxy real IP’s.

step 2) HAProxy has valid API ACL and backend server configurations.IF HAProxy allowed POST “/v2.0/tokens”, then the request call to ext-api-wrapper0[12].

public API: step 3), step 4)

step 3) ext-api-wrapper0 [12], it is a php program.request URI and header, and the input value of json of the body was confirmed by php, and then call the real OpenStack API as the next processing.

step 4) OpenStack API that is checked the input value will be run.

– Flat-VLAN + Neutron ML2 ovs-VXLAN overlay + ML2 LinuxBridge(SaaS only)

– IPv6/IPv4 dualstack• LBaaS: LVS-DSR(original)• Public API

– Provided the public API (v2 Domain)• Compute node: ALL SSD for booting OS

– Without Cinder boot • Glance: provided• Cinder: SSD NexentaStore zfs (SDS)• Swift (shared Juno cluster)• Cobbler deply on under-cloud

– Ansible configuration• SaaS original service with keystone auth

– Email, web, CPanel and WordPress

– L4-LB-Nat + Neutron ML2 LinuxBridge VLAN– IPv4 only

• LBaaS: Brocade ADX L4-NAT-LB(original)• Public API

– Provided the public API• Compute node: Flash cached or SSD• Glance: provided (NetApp offload)• Cinder: NetApp storage• Swift (shared Juno cluster)• Ironic on under-cloud

– Compute server deploy with Ansible config• Ironic baremetal compute

– Nexsus Cisco for Tagged VLAN module– ioMemory configuration

NetApp storage: GMO AppsCloud(Havana/Juno)If you are using the same Cluster onTAP

NetApp a Glance and Cinder storage, it is possible to offload a copy of the inter-service of OpenStack as the processing of NetApp side.

• Create volume from glance image

((glance the image is converted (ex: qcow2 to raw) required that does not cause the condition)

• Volume QoS limit: Important function of multi-tenant storage• Uppper IOPS-limit by volume

OpenStack Ironic: Only AppsCloud:• Undercloud Ironic deploy• Multi-tenant Ironic deploy

Ironic with undercloud: GMO AppsCloud(Juno)For Compute server deployment.Kilo Ironic and All-in-one• Compute server: 10G boot• Clout-init: network• Compute setup: Ansible

Under-cloud Ironic(Kilo):It will use a different network and Ironic Baremetal dhcp for Service baremetal compute Ironic(Kilo).(OOO seed server)
