Apache CloudStack is an effort undergoing incubation at The Apache Software Foundation (ASF).

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

1.1. What Is CloudStack?

CloudStack is an open source software platform that pools computing resources to build public, private, and hybrid Infrastructure as a Service (IaaS) clouds. CloudStack manages the network, storage, and compute nodes that make up a cloud infrastructure. Use CloudStack to deploy, manage, and configure cloud computing environments.

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.

1.2. What Can CloudStack Do?

Multiple Hypervisor Support

CloudStack works with a variety of hypervisors, and a single cloud deployment can contain multiple hypervisor implementations. The current release of CloudStack supports pre-packaged enterprise solutions like Citrix XenServer and VMware vSphere, as well as KVM or Xen running on Ubuntu or CentOS.

Massively Scalable Infrastructure Management

CloudStack can manage tens of thousands of servers installed in multiple geographically distributed datacenters. The centralized management server scales linearly, eliminating the need for intermediate cluster-level management servers. No single component failure can cause cloud-wide outage. Periodic maintenance of the management server can be performed without affecting the functioning of virtual machines running in the cloud.

Automatic Configuration Management

CloudStack automatically configures each guest virtual machine’s networking and storage settings.

CloudStack internally manages a pool of virtual appliances to support the cloud itself. These appliances offer services such as firewalling, routing, DHCP, VPN access, console proxy, storage access, and storage replication. The extensive use of virtual appliances simplifies the installation, configuration, and ongoing management of a cloud deployment.

Graphical User Interface

CloudStack offers an administrator's Web interface, used for provisioning and managing the cloud, as well as an end-user's Web interface, used for running VMs and managing VM templates. The UI can be customized to reflect the desired service provider or enterprise look and feel.

API and Extensibility

CloudStack provides an API that gives programmatic access to all the management features available in the UI. The API is maintained and documented. This API enables the creation of command line tools and new user interfaces to suit particular needs. See the Developer’s Guide and API Reference, both available at Apache CloudStack Guides and Apache CloudStack API Reference respectively.

The CloudStack pluggable allocation architecture allows the creation of new types of allocators for the selection of storage and Hosts. See the Allocator Implementation Guide (http://docs.cloudstack.org/CloudStack_Documentation/Allocator_Implementation_Guide).

High Availability

CloudStack has a number of features to increase the availability of the system. The Management Server itself may be deployed in a multi-node installation where the servers are load balanced. MySQL may be configured to use replication to provide for a manual failover in the event of database loss. For the hosts, CloudStack supports NIC bonding and the use of separate networks for storage as well as iSCSI Multipath.

1.3. Deployment Architecture Overview

A CloudStack installation consists of two parts: the Management Server and the cloud infrastructure that it manages. When you set up and manage a CloudStack cloud, you provision resources such as hosts, storage devices, and IP addresses into the Management Server, and the Management Server manages those resources.

The minimum production installation consists of one machine running the CloudStack Management Server and another machine to act as the cloud infrastructure (in this case, a very simple infrastructure consisting of one host running hypervisor software). In its smallest deployment, a single machine can act as both the Management Server and the hypervisor host (using the KVM hypervisor).

basic-deployment.png: Basic two-machine deployment

A more full-featured installation consists of a highly-available multi-node Management Server installation and up to tens of thousands of hosts using any of several advanced networking setups. For information about deployment options, see Choosing a Deployment Architecture.

1.3.1. Management Server Overview

The Management Server is the CloudStack software that manages cloud resources. By interacting with the Management Server through its UI or API, you can configure and manage your cloud infrastructure.

The Management Server runs on a dedicated server or VM. It controls allocation of virtual machines to hosts and assigns storage and IP addresses to the virtual machine instances. The Management Server runs in a Tomcat container and requires a MySQL database for persistence.

The machine must meet the system requirements described in System Requirements.

The Management Server:

Provides the web user interface for the administrator and a reference user interface for end users.
Provides the APIs for CloudStack.
Manages the assignment of guest VMs to particular hosts.
Manages the assignment of public and private IP addresses to particular accounts.
Manages the allocation of storage to guests as virtual disks.
Manages snapshots, templates, and ISO images, possibly replicating them across data centers.
Provides a single point of configuration for the cloud.

1.3.2. Cloud Infrastructure Overview

The Management Server manages one or more zones (typically, datacenters) containing host computers where guest virtual machines will run. The cloud infrastructure is organized as follows:

Zone: Typically, a zone is equivalent to a single datacenter. A zone consists of one or more pods and secondary storage.
Pod: A pod is usually one rack of hardware that includes a layer-2 switch and one or more clusters.
Cluster: A cluster consists of one or more hosts and primary storage.
Host: A single compute node within a cluster. The hosts are where the actual cloud services run in the form of guest virtual machines.
Primary storage is associated with a cluster, and it stores the disk volumes for all the VMs running on hosts in that cluster.
Secondary storage is associated with a zone, and it stores templates, ISO images, and disk volume snapshots.

More Information

For more information, see documentation on cloud infrastructure concepts.

1.3.3. Networking Overview

CloudStack offers two types of networking scenario:

Basic. For AWS-style networking. Provides a single network where guest isolation can be provided through layer-3 means such as security groups (IP address source filtering).
Advanced. For more sophisticated network topologies. This network model provides the most flexibility in defining guest networks.

For more details, see Network Setup.

Chapter 2. Introduction for Developers

2.1. Roles
2.2. API Reference Documentation
2.3. Getting Started

2.1. Roles

The CloudPlatform API supports three access roles:

Root Admin. Access to all features of the cloud, including both virtual and physical resource management.
Domain Admin. Access to only the virtual resources of the clouds that belong to the administrator’s domain.
User. Access to only the features that allow management of the user’s virtual instances, storage, and network.

2.2. API Reference Documentation

2.2 API Reference:

http://download.cloud.com/support/downloads.html/

3.0 API Reference:

http://download.cloud.com/releases/3.0.0/api_3.0.0/TOC_Root_Admin.html/

2.3. Getting Started

To get started using the CloudStack API, you should have the following:

URL of the CloudStack server you wish to integrate with.
Both the API Key and Secret Key for an account. This should have been generated by the administrator of the cloud instance and given to you.
Familiarity with HTTP GET/POST and query strings.
Knowledge of either XML or JSON.
Knowledge of a programming language that can generate HTTP requests; for example, Java or PHP.

3.2. What's New in the API for 3.0

3.2.1. Enabling Port 8096

Port 8096, which allows API calls without authentication, is closed and disabled by default on any fresh 3.0.1 installations. You can enable 8096 (or another port) for this purpose as follows:

Ensure that the first Management Server is installed and running.
Set the global configuration parameter integration.api.port to the desired port.
Restart the Management Server.
On the Management Server host machine, create an iptables rule allowing access to that port.

3.2.2. Stopped VM

CloudStack now supports creating a VM without starting it. You can determine whether the VM needs to be started as part of the VM deployment. A VM can now be deployed in two ways: create and start a VM (the default method); or create a VM and leave it in the stopped state.

A new request parameter, startVM, is introduced in the deployVm API to support the stopped VM feature.

The possible values are:

true - The VM starts as a part of the VM deployment.
false - The VM is left in the stopped state at the end of the VM deployment.

The default value is true.

3.2.3. Change to Behavior of List Commands

There was a major change in how our List* API commands work in CloudStack 3.0 compared to 2.2.x. The rules below apply only for managed resources – those that belong to an account, domain, or project. They are irrelevant for the List* commands displaying unmanaged (system) resources, such as hosts, clusters, and external network resources.

When no parameters are passed in to the call, the caller sees only resources owned by the caller (even when the caller is the administrator). Previously, the administrator saw everyone else's resources by default.

When accountName and domainId are passed in:

The caller sees the resources dedicated to the account specified.
If the call is executed by a regular user, the user is authorized to specify only the user's own account and domainId.
If the caller is a domain administrator, CloudStack performs an authorization check to see whether the caller is permitted to view resources for the given account and domainId.

When projectId is passed in, only resources belonging to that project are listed.

When domainId is passed in, the call returns only resources belonging to the domain specified. To see the resources of subdomains, use the parameter isRecursive=true. Again, the regular user can see only resources owned by that user, the root administrator can list anything, and a domain administrator is authorized to see only resources of the administrator's own domain and subdomains.

To see all resources the caller is authorized to see, except for Project resources, use the parameter listAll=true.

To see all Project resources the caller is authorized to see, use the parameter projectId=-1.

There is one API command that doesn't fall under the rules above completely: the listTemplates command. This command has its own flags defining the list rules:

listTemplates Flag	Description
featured	Returns templates that have been marked as featured and public.
self	Returns templates that have been registered or created by the calling user.
selfexecutable	Same as self, but only returns templates that are ready to be deployed with.
sharedexecutable	Ready templates that have been granted to the calling user by another user.
executable	Templates that are owned by the calling user, or public templates, that can be used to deploy a new VM.
community	Returns templates that have been marked as public but not featured.
all	Returns all templates (only usable by admins).

The CloudStack UI on a general view will display all resources that the logged-in user is authorized to see, except for project resources. To see the project resources, select the project view.

3.2.4. Removed API commands

configureSimulator (Configures simulator)

3.2.5. Added API commands in 3.0

4.1. Making API Requests

All CloudStack API requests are submitted in the form of a HTTP GET/POST with an associated command and any parameters. A request is composed of the following whether in HTTP or HTTPS:

CloudStack API URL: This is the web services API entry point(for example, http://www.cloud.com:8080/client/api)
Command: The web services command you wish to execute, such as start a virtual machine or create a disk volume
Parameters: Any additional required or optional parameters for the command

A sample API GET request looks like the following:

http://localhost:8080/client/api?command=deployVirtualMachine&serviceOfferingId=1&diskOfferingId=1&templateId=2&zoneId=4&apiKey=miVr6X7u6bN_sdahOBpjNejPgEsT35eXq-jB8CG20YI3yaxXcgpyuaIRmFI_EJTVwZ0nUkkJbPmY3y2bciKwFQ&signature=Lxx1DM40AjcXU%2FcaiK8RAP0O1hU%3D

Or in a more readable format:

1. http://localhost:8080/client/api
2. ?command=deployVirtualMachine
3. &serviceOfferingId=1
4. &diskOfferingId=1
5. &templateId=2
6. &zoneId=4
7. &apiKey=miVr6X7u6bN_sdahOBpjNejPgEsT35eXqjB8CG20YI3yaxXcgpyuaIRmFI_EJTVwZ0nUkkJbPmY3y2bciKwFQ

The first line is the CloudStack API URL. This is the Cloud instance you wish to interact with.

The second line refers to the command you wish to execute. In our example, we are attempting to deploy a fresh new virtual machine. It is preceded by a (?) to separate itself from the CloudStack API URL.

Lines 3-6 are the parameters for this given command. To see the command and its request parameters, please refer to the appropriate section in the CloudStack API documentation. Each parameter field-value pair (field=value) is preceded by an ampersand character (&).

Line 7 is the user API Key that uniquely identifies the account. See Signing API Requests on page 7.

Line 8 is the signature hash created to authenticate the user account executing the API command. See Signing API Requests on page 7.

4.2. Enabling API Call Expiration

You can set an expiry timestamp on API calls to prevent replay attacks over non-secure channels, such as HTTP. The server tracks the expiry timestamp you have specified and rejects all the subsequent API requests that come in after this validity period.

To enable this feature, add the following parameters to the API request:

signatureVersion=3: If the signatureVersion parameter is missing or is not equal to 3, the expires parameter is ignored in the API request.
expires=YYYY-MM-DDThh:mm:ssZ: Specifies the date and time at which the signature included in the request is expired. The timestamp is expressed in the YYYY-MM-DDThh:mm:ssZ format, as specified in the ISO 8601 standard.

For example:

expires=2011-10-10T12:00:00+0530

A sample API request with expiration is given below:

http://<IPAddress>:8080/client/api?command=listZones&signatureVersion=3&expires=2011-10-10T12:00:00+0530&apiKey=miVr6X7u6bN_sdahOBpjNejPgEsT35eXq-jB8CG20YI3yaxXcgpyuaIRmFI_EJTVwZ0nUkkJbPmY3y2bciKwFQ&signature=Lxx1DM40AjcXU%2FcaiK8RAP0O1hU%3D

4.3. Signing API Requests

Whether you access the CloudStack API with HTTP or HTTPS, it must still be signed so that CloudStack can verify the caller has been authenticated and authorized to execute the command. Make sure that you have both the API Key and Secret Key provided by the CloudStack administrator for your account before proceeding with the signing process.

To show how to sign a request, we will re-use the previous example.

http://http://localhost:8080/client/api?command=deployVirtualMachine&serviceOfferingId=1&diskOfferingId=1&templateId=2&zoneId=4&apiKey=miVr6X7u6bN_sdahOBpjNejPgEsT35eXq-jB8CG20YI3yaxXcgpyuaIRmFI_EJTVwZ0nUkkJbPmY3y2bciKwFQ&signature=Lxx1DM40AjcXU%2FcaiK8RAP0O1hU%3D

Breaking this down, we have several distinct parts to this URL.

Base URL: This is the base URL to the CloudStack Management Server.
```
http://localhost:8080
```
API Path: This is the path to the API Servlet that processes the incoming requests.
```
/client/api?
```
Command String: This part of the query string comprises of the command, its parameters, and the API Key that identifies the account.
Note
As with all query string parameters of field-value pairs, the "field" component is case insensitive while all "value" values are case sensitive.
```
command=deployVirtualMachine&serviceOfferingId=1&diskOfferingId=1&templateId=2&zoneId=4&apiKey=miVr6X7u6bN_sdahOBpjNejPgEsT35eXq-jB8CG20YI3yaxXcgpyuaIRmFI_EJTVwZ0nUkkJbPmY3y2bciKwFQ
```
Signature: This is the hashed signature of the Base URL that is generated using a combination of the user’s Secret Key and the HMAC SHA-1 hashing algorithm.
&signature=Lxx1DM40AjcXU%2FcaiK8RAP0O1hU%3D

Every API request has the format Base URL+API Path+Command String+Signature.

To generate the signature.

For each field-value pair (as separated by a '&') in the Command String, URL encode each value so that it can be safely sent via HTTP GET.
Note
Make sure all spaces are encoded as "%20" rather than "+".

Lower case the entire Command String and sort it alphabetically via the field for each field-value pair. The result of this step would look like the following.

apikey=mivr6x7u6bn_sdahobpjnejpgest35exq-jb8cg20yi3yaxxcgpyuairmfi_ejtvwz0nukkjbpmy3y2bcikwfq&command=deployvirtualmachine&diskofferingid=1&serviceofferingid=1&templateid=2&zoneid=4

Take the sorted Command String and run it through the HMAC SHA-1 hashing algorithm (most programming languages offer a utility method to do this) with the user’s Secret Key. Base64 encode the resulting byte array in UTF-8 so that it can be safely transmitted via HTTP. The final string produced after Base64 encoding should be "Lxx1DM40AjcXU%2FcaiK8RAP0O1hU%3D".
By reconstructing the final URL in the format Base URL+API Path+Command String+Signature, the final URL should look like:
```
http://localhost:8080/client/api?command=deployVirtualMachine&serviceOfferingId=1&diskOfferingId=1&templateId=2&zoneId=4&apiKey=miVr6X7u6bN_sdahOBpjNejPgEsT35eXq-jB8CG20YI3yaxXcgpyuaIRmFI_EJTVwZ0nUkkJbPmY3y2bciKwFQ&signature=Lxx1DM40AjcXU%2FcaiK8RAP0O1hU%3D
```

4.4. Responses

4.4.1. Response Formats: XML and JSON

CloudStack supports two formats as the response to an API call. The default response is XML. If you would like the response to be in JSON, add &response=json to the Command String.

Sample XML Response:

     <listipaddressesresponse> 
        <allocatedipaddress>
        <ipaddress>192.168.10.141</ipaddress> 
        <allocated>2009-09-18T13:16:10-0700</allocated> 
        <zoneid>4</zoneid> 
            <zonename>WC</zonename> 
            <issourcenat>true</issourcenat> 
        </allocatedipaddress>
     </listipaddressesresponse>

Sample JSON Response:

        { "listipaddressesresponse" : 
          { "allocatedipaddress" :
            [ 
              { 
                "ipaddress" : "192.168.10.141", 
                "allocated" : "2009-09-18T13:16:10-0700",
                "zoneid" : "4", 
                "zonename" : "WC", 
                "issourcenat" : "true" 
              } 
            ]
          } 
        }

4.4.2. Maximum Result Pages Returned

For each cloud, there is a default upper limit on the number of results that any API command will return in a single page. This is to help prevent overloading the cloud servers and prevent DOS attacks. For example, if the page size limit is 500 and a command returns 10,000 results, the command will return 20 pages.

The default page size limit can be different for each cloud. It is set in the global configuration parameter default.page.size. If your cloud has many users with lots of VMs, you might need to increase the value of this parameter. At the same time, be careful not to set it so high that your site can be taken down by an enormous return from an API call. For more information about how to set global configuration parameters, see "Describe Your Deployment" in the Installation Guide.

To decrease the page size limit for an individual API command, override the global setting with the page and pagesize parameters, which are available in any list* command (listCapabilities, listDiskOfferings, etc.).

Both parameters must be specified together.
The value of the pagesize parameter must be smaller than the value of default.page.size. That is, you can not increase the number of possible items in a result page, only decrease it.

For syntax information on the list* commands, see the API Reference.

4.4.3. Error Handling

If an error occurs while processing an API request, the appropriate response in the format specified is returned. Each error response consists of an error code and an error text describing what possibly can go wrong. For an example error response, see page 12.

An HTTP error code of 401 is always returned if API request was rejected due to bad signatures, missing API Keys, or the user simply did not have the permissions to execute the command.

4.5. Asynchronous Commands

Asynchronous commands were introduced in CloudStack 2.x. Commands are designated as asynchronous when they can potentially take a long period of time to complete such as creating a snapshot or disk volume. They differ from synchronous commands by the following:

They are identified in the API Reference by an (A).
They will immediately return a job ID to refer to the job that will be responsible in processing the command.
If executed as a "create" resource command, it will return the resource ID as well as the job ID.
You can periodically check the status of the job by making a simple API call to the command, queryAsyncJobResult and passing in the job ID.

4.5.1. Job Status

The key to using an asynchronous command is the job ID that is returned immediately once the command has been executed. With the job ID, you can periodically check the job status by making calls to queryAsyncJobResult command. The command will return three possible job status integer values:

0 - Job is still in progress. Continue to periodically poll for any status changes.
1 - Job has successfully completed. The job will return any successful response values associated with command that was originally executed.
2 - Job has failed to complete. Please check the "jobresultcode" tag for failure reason code and "jobresult" for the failure reason.

4.5.2. Example

The following shows an example of using an asynchronous command. Assume the API command:

command=deployVirtualMachine&zoneId=1&serviceOfferingId=1&diskOfferingId=1&templateId=1

CloudStack will immediately return a job ID and any other additional data.

         <deployvirtualmachineresponse> 
              <jobid>1</jobid>
             <id>100</id>
         </deployvirtualmachineresponse>

Using the job ID, you can periodically poll for the results by using the queryAsyncJobResult command.

command=queryAsyncJobResult&jobId=1

Three possible results could come from this query.

Job is still pending:

         <queryasyncjobresult> 
              <jobid>1</jobid>
              <jobstatus>0</jobstatus>
              <jobprocstatus>1</jobprocstatus>
         </queryasyncjobresult>

Job has succeeded:

            <queryasyncjobresultresponse cloud-stack-version="3.0.1.6">
                  <jobid>1</jobid>
                  <jobstatus>1</jobstatus>
                  <jobprocstatus>0</jobprocstatus>
                 <jobresultcode>0</jobresultcode>

5.4. Dates in the Usage Record

The Usage Server provides aggregated usage records which you can use to create billing integration for the CloudStack platform. The Usage Server works by taking data from the events log and creating summary usage records that you can access using the listUsageRecords API call.

The usage records show the amount of resources, such as VM run time or template storage space, consumed by guest instances. In the special case of bare metal instances, no template storage resources are consumed, but records showing zero usage are still included in the Usage Server's output.

The Usage Server runs at least once per day. It can be configured to run multiple times per day. Its behavior is controlled by configuration settings as described in the CloudStack Administration Guide.

5.3. Example response from listUsageRecords

All CloudStack API requests are submitted in the form of a HTTP GET/POST with an associated command and any parameters. A request is composed of the following whether in HTTP or HTTPS:

            <listusagerecordsresponse>
                  <count>1816</count>

5.4. Dates in the Usage Record

Usage records include a start date and an end date. These dates define the period of time for which the raw usage number was calculated. If daily aggregation is used, the start date is midnight on the day in question and the end date is 23:59:59 on the day in question (with one exception; see below). A virtual machine could have been deployed at noon on that day, stopped at 6pm on that day, then started up again at 11pm. When usage is calculated on that day, there will be 7 hours of running VM usage (usage type 1) and 12 hours of allocated VM usage (usage type 2). If the same virtual machine runs for the entire next day, there will 24 hours of both running VM usage (type 1) and allocated VM usage (type 2).

Note: The start date is not the time a virtual machine was started, and the end date is not the time when a virtual machine was stopped. The start and end dates give the time range within which usage was calculated.

For network usage, the start date and end date again define the range in which the number of bytes transferred was calculated. If a user downloads 10 MB and uploads 1 MB in one day, there will be two records, one showing the 10 megabytes received and one showing the 1 megabyte sent.

There is one case where the start date and end date do not correspond to midnight and 11:59:59pm when daily aggregation is used. This occurs only for network usage records. When the usage server has more than one day's worth of unprocessed data, the old data will be included in the aggregation period. The start date in the usage record will show the date and time of the earliest event. For other types of usage, such as IP addresses and VMs, the old unprocessed data is not included in daily aggregation.
