Measured Service

What is the cloud? The Cloud is AWESOME

What kind of clouds?
SaaS
PaaS
IaaS
Compute
Storage
Networking

What is CloudStack? Free (as in speech, and beer) Infrastructure as a Service implementation that supports multiple hypervisors, complex network and firewall configuration, high-availability, and complex multi-tenant offerings.

What do IaaS Cloud Platforms really do?
Manage HA
Provision networking services (load balancing, dhcp, routing, VLAN allocation, firewall, isolation, VPN, manage external networking elements)
Allocate VM/resources based on algorithms and availability
Provide abstraction of and interaction with virtualization, networking, etc.

What do IaaS Cloud Platforms really do?
Provide a multi-tenant, highly segregated, interface (API or web interface)
Allow arbitrary resources limits to be placed on accounts or users.
Track not just counts of VMs at given point in time, but usage (type of instance, network, storage, CPU) over time.

Multiple hypervisor support
KVM
XenServer
XCP
VMware
OVM
Baremetal

Multi-tenant
Resources are hierarchically segregated into Zones, Pods, Clusters, and Hosts
Users are separated into multi-level domains and accounts and granted varying degrees of access to resources.
Users and Admins have access to the same UI

Networking
CloudStack manages networking including:
Load Balancing
VPN
Firewall
Routing
DHCP
VLAN provisioning and management
Security Groups

High Availability
CloudStack, upon noticing an instance failing will attempt to restart the node, and failing that will create a new instance on a different piece of hardware in the cluster.
Works for all supported hypervisors.
System VMs such as router and loadbalancer are HA by default
Redundant router

Robust API CloudStack is replete with a robust RESTful API (output in XML or JSON) Allows external applications such as monitoring to perform actions such as spinning up new instances in response to load. Allows you to loosely couple external applications such as billing and PaaS to CloudStack.

Overall (simplified) Architecture
Management Server/Database
Compute nodes
Primary Storage
Secondary Storage
Virtual resources
Router (routing, firewall, load balancer, VPN)
ConsoleProxy

Resources Physical resources divided up into:
Zone
Pod
Cluster
Hosts
Storage (tags)
