Management Server

The Management Server gives the Administrator the ability to orchestrate the CloudPlatform environment through the administrative Web UI and APIs

The Management Server is installed on one or more servers connected to a MySQL database

Management Server

51

Management Server

A single Management Server can manage anywhere from 1 to 10,000 hosts in multiple Availability Zones, across multiple datacenters

A Cluster of Management Servers can manage up to 100,000 hosts with a single pane of glass

West Coast East Coast

52

Management Server Requirements

The server that will run the management server and MySQL database must meet the following requirements:• Operating system:

- Preferred: RHEL or CentOS 6.2, 6.3 or 6.4 64-bit- Also supported: RHEL 5.5 64-bit

• 64-bit x86 CPU (more cores results in better performance)• 4 GB of memory• 50GB of local disk minimum; 500 GB of local disk recommended• At least 1 GB or better NIC• Statically allocated IP address• Fully qualified domain name (as returned by the hostname command)

The management server may be placed on a virtual machine.

53

Host/Hypervisor System Requirements

The Host is where the cloud services run in the form of guest virtual machines

Each host must meet the vendors’ minimum requirements:- Must support HVM (Intel-VT or AMD-V enabled)- 64-bit x86 CPU- 4 GB of memory- 16 GB+ disk for virtualization platform and VMs- Statically allocated IP address

The latest hypervisor software hotfixes should be applied to all hosts

All hosts within a cluster must be homogenous• The CPUs must be of the same type, count, feature flags and running the same hypervisor

54

What are the CloudPlatform System VMs?

CloudPlatform uses several types of System Appliances (System VMs) to perform various tasks in the cloud• The Console Proxy System VM• The Secondary Storage System VM• The Virtual Router System VM

The System VMs run on the same hosts as the Guest VMs

CloudPlatform manages these System VMs, creating them, starting them and stopping them as needed, based on scale and immediate needs

55

Console Proxy System VM

The Console Proxy has a role in presenting a console view via the web UI

It connects the user’s browser to the VNC port made available via the hypervisor for the console of the Guest

Both the administrator and end user web UIs offer a console connection

56

Secondary Storage System VM

Handles a variety of Secondary Storage activities• Importing (Registering) a new Template to a Zone (from a URL)• Exporting (Extracting) a Template from a Zone (to a URL)• Copying Templates between Zones• Copying a Template from Secondary Storage to Primary Storage when a VM is created for the

first time on a particular Cluster• Snapshot backups

57

Virtual Router System VM

The Virtual Router System VM is one of the most frequently used service providers

Virtual Router Services offered can include• DHCP, DNS, LB, Port Forwarding, VPN, Static NAT, Source NAT, Firewall, Gateway, Network

ACL, Security Groups, User Data

There is one Virtual Router per network

The end user can configure the Virtual Router using the CloudPlatform GUI or API

58

The System VM Template

Used to create all System VMs

The template must be “seeded” to the secondary storage for each Zone before the Zone is created in CloudPlatform

During setup a script copies the template from the internet repository into secondary storage, and seeds the mySQL database

The zone must be seeded with a different template for each hypervisor

Define the virtual hardware used to run guest VMs

Includes CPU core count, processor speed and RAM size

78

Disk Offerings

Define the size of a Data Disk for Guest VMs created from a Template

Define the size of the Root Volume for Guest VMs created from an ISO

79

Network Offerings

Describe the virtual router features available to VMs on a given guest network

Examples are shared network, isolated network, NetScaler powered network

80

System Offerings

Used for configuring virtual infrastructure resources

Only visible only to the CloudPlatform administrator

81

Changing the Compute Offering used by a VM

The compute offering used by a VM can be changed

While the VM is Stopped, a user can change a VM’s Compute Offering to any available offering

While the VM is Running, a user can change a VM’s Compute Offering with the following restrictions• The same or more Cores• The same or larger RAM (but only up to four times original size)

82

Service Offering Limits

Service offering limits (e.g. 1 GHz, 1 core) are strictly enforced for core count

For example, a guest with a service offering of one core will have the use of one core, regardless of how many cores are available

Service offering limits for gigahertz are enforced only in the presence of contention for CPU resources• A single VM running on a Host will have the full clock speed of the CPU available to it• Multiple VMs running on a Host will use a weighting factor based on the clock speed in

Service Offering to schedule CPU resources

83

Compute Offering Tip

A 2GHz processor may be slightly less than 2000MHz … maybe 1997MHz !

Since the hypervisor uses the actual MHz for provisioning, this will cause any offering needing 2000MHz to fail to find a suitable Host

On XenServer check the actual CPU speed in /proc/cpuinfo

84

Dedicated Resources

When added to CloudPlatform, hardware resources can be dedicated to a specific Domain or Account

Dedicating a Zone, Pod, Cluster or Host to a specific Domain or Account means that the Domain or Account will have sole access to the dedicated hardware

Dedication can improve the scalability, security and manageability within a Domain or Account

85

Acme Corporation

Accounts, Users and Domains

Accounts typically represent a customer • For example an organization, a department or a person

Accounts form isolation blocks• One account has no access to another account’s resources

Users are the “Admins” for an account

Can be more than one user per account• All account’s resources are shared between users

Domains group accounts

Domain-Admin can manage all of the resources of all accounts within the Domain

101

Virtual Machines Names

Guest VMs have a Name and Group

The CloudPlatform DHCP server will assign this name to the VM

This name cannot be changed in CloudPlatform after VM creation

If you don’t provide a name, CloudPlatform will create one for you

102

Virtual Machines Names

Each VM can also has a Display Name

It defaults to the name entered in the wizard

This name can be edited by the user (when the VM is stopped)

103

An additional VM name is used internally by CloudPlatform and is visible in the administrator console and the hypervisor management console

CloudPlatform uses an internal VM naming structure for all VMs as follows• First letter is

- iGuest VM (Instance)- r Virtual Router System VM- s Secondary Storage System VM- v Console Proxy System VM

• Second digit is the account number (omitted for System VMs)- 2 admin- 3 First account- 4 Second account etc.

• Followed by a cloud-wide VM number- 3 First VM- 4 Second VM etc.

111

High Availability VMs

Compute Offerings may include High Availability (HA) for the VM

HA enabled VMs are monitored by the system

If the system detects that an HA VM is down, it will attempt to restart the VM

CloudPlatform must be used to shutdown an HA VM, or else CloudPlatform will attempt to restart the VM

112

Accessing VMs

Using the CloudPlatform GUI to access the VM console• The CloudPlatform Administrator can access all VMs running in the cloud• The Domain Administrator can access all VMs running in their domain• A user can access any VM in their account

Various protocols such as ssh or RDP can also be used for VM access

113

TemplateTemplate

Templates

A Template is file containing a Virtual Disk Image (VDI) of a boot disk

It includes the operating system and optional application software

When users launch VMs, they choose from a list of Templates to use as a base

130

Templates

Each Template is associated with a particular type of hypervisor

CloudPlatform has a built-in CentOS Template that can be used for testing

Templates can be imported into CloudPlatform by the Administrator or by Users

A Template can be created from a VM already in CloudPlatform

Templates can be designated Private or Public• Private Templates are only available to the user who created them• Public Templates are available to all users who have access to the Zone

131

Registering (Importing) a Template

Template file must be first placed onto a web server accessible by CloudPlatform• Maybe a little cumbersome, but an extremely flexible solution

Using the Register Template wizard enter the following• Unique name for the Template (visible to users)• Description for the Template (visible to users)• URL to download the Template from• The Zone the Template will be available in• The hypervisor used in the creation of the Template• The data format of the Template upload file• The OS used in the Template

132

Registering a Template

Options• Can the Template be exported from CloudPlatform• Template has the password change script installed• Allows switching to another compute offering without stopping the VM • Template is available to all users who have access to the Zone• Template appears in the Featured list• Template is used to create a Router

133

Supported Template Disk Formats
