CloudStack[wp] Is open source cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisors such as KVM, vSphere, and XenServer for virtualization.

CloudStack manages the network, storage, and compute nodes that make up a cloud infrastructure

What Is CS ?Typical users are service providers and enterprises. With CloudStack, you can: ● Set up an on-demand, elastic cloud computing service.

Service providers can sell self service virtual machine instances, storage volumes, and networking configurations over the Internet.

● Set up an on-premise private cloud for use by employees. Rather than managing virtual machines in the same way as physical machines, with CloudStack an enterprise can offer self-service virtual machines to users without involving IT departments.

What Can CS Do?● Multiple Hypervisor Support● Automatic Configuration Management

○ firewalling ○ routing ○ DHCP○ VPN access○ console proxy○ storage access, and storage replication

● Graphical User Interface● API and Extensibility● High Availability

Overview

Zone overviewA zone typically corresponds to a single datacenter, although it is permissible to have multiple zones in a datacenter.provide physical isolation andredundancyFor each zone, the administrator must decide the following.

● How many pods to place in each zone. ● How many clusters to place in each pod. ● How many hosts to place in each cluster. ● (Optional) How many primary storage servers to place

in each zone and total capacity for these storage servers.

● How many primary storage servers to place in eachcluster and total capacity for these storage servers.

● How much secondary storage to deploy in a zone.

Pod OverviewRepresents a single rack. Hosts in the same pod are in the same subnet.Pods are contained within zones. Each zone can contain one or more pods. A podconsists of one or more clusters of hosts and one or more primarystorage servers.

Cluster Overview* A cluster provides a way to group hosts* A cluster is a XenServer server pool, a set of KVM servers, or a VMware cluster* The hosts in a cluster all have identical hardware, run the same hypervisor, are on the same subnet, and access the same shared primary storage. Virtual machine instances (VMs) can be live-migrated from one host to another within the same cluster, without interrupting service to the user.

Network Traffic Types1. Guest2. Management3. Public4. Storage

Network Traffic Types1. Guest: When end users run VMs, they

generate guest traffic. The guest VMs communicate with each other over a network that can be referred to as the guest network. In an isolated guest network, the administrator needs to reserve VLAN ranges to provide isolation for each CloudStack account’s network. In a shared guest network, all guest VMs share a single network.

Network Traffic Types2. Management: When CloudStack’s internal resources communicate with each other, they generate management traffic. This includes communication between hosts, system VMs and any other component that communicates directly with the CloudStack Management Server. You must configure the IP range for the system VMs to use.

Network Traffic Types3. Public: Public traffic is generated when VMs in the cloud access the Internet. Publicly accessible IPs must be allocated for this purpose. End users can use the CloudStack UI to acquire these IPs to implement NAT between their guest network and the public network, as described in “Acquiring a New IP Address” in the Administration Guide.

Network Traffic Types4. Storage: While labeled "storage" this is specifically about secondary storage, and doesn't affect traffic for primary storage. This includes traffic such as VM templates and snapshots, which is sent between the secondary storage VM and secondary storage servers. CloudStack uses a separate Network Interface Controller (NIC) named storage NIC for storage network traffic.
