System components

QCloud accesses digital media from local storage, such as a local hard drive or DVD, as well as network storage, such as a Windows ﬁle server, FTP server, or s3 bucket.

A QCloud system can be set up in three basic ways:

The ﬁrst consists of a single self-contained unit which runs all the management and testing processes

of the system.

The second consists of a networked cluster of two or more units, which enables simultaneous

processing of a greater number of ﬁles. The networked cluster contains a single Supervisor and one

or more Media Test Units.

The third consists of a cluster of three or more units with high availability (HA) support. QCloud

Enterprise Cluster with high availability (also referred to as an HA cluster) is a QCloud cluster enabled

with support in the case of a Supervisor system failure.

Security groups conﬁguration within a VPC for QCloud

A security group is a ﬁrewall that regulates the ﬂow of trafﬁc across the EC2s within a VPC network on Cloud. Each EC2 can be associated with a particular available security group. The security group contains a set of rules that allow or disallow inbound and outbound trafﬁc to those EC2s. Multiple security groups can be conﬁgured within a VPC. The security group should be conﬁgured in such a way that it allows both inbound and outbound trafﬁc across a cluster of EC2s. At the same time, it secures the systems from ex

ternal communication.

Example conﬁguration of a security group

In the EC2 management console, open EC2 dashboard. Click on the “Security Groups” option under the “Network and Security” section. This will list down all the available security groups. Note that this list displays the “Group Id” for each of the security groups. Select the security group to be updated with the rules. The lower panel will display the security group details.

to set inbound rules. The following procedure shows you how to set inbound rules.

How

1. Select the “Inbound” tab.

2. Select “Custom TCP rule” from the “Create a new rule” selection box.

3. In the “Port Range” text box, enter 0-65535. This will open up all available ports on TCP.

4. In the “Source” text box, enter the ID of the security group. Each security group will come with an

id assigned to it in the form E.g.-<abcd1234>. This is same as the one displayed under “Group Id” column mentioned above for this security group.

5. Setting Outbound rules: 1: Select the Outbound tab. 2: Select “All TCP rule” from the “Create a new rule” selection box. 3: In the “Source” text box, enter 0.0.0.0/0 Basically this rule allows all TCP trafﬁc between the EC2s that are associated with this security group. Also, this allows all trafﬁcfromtheEC2totheoutside.

QCloud high availability enterprise cluster

The QCloud high availability enterprise cluster (also referred to as an HA cluster) is a QCloud cluster enabled with support in the case of a Supervisor system failure. In an HA cluster, one of the member units of the cluster is conﬁgured as a backup to the Primary Supervisor and is called the Secondary Supervisor.

If QCloud on the Primary Supervisor goes down for any reason (for example, du Secondary Supervisor automatically takes over and manages the cluster. All other units (MTUs) now form a cluster with the Secondary Supervisor. Once the Primary Supervisor recovers, it w ill assume the role of the Secondary Supervisor and will be ready to take over when the current Supervisor goes down.

The Secondary Supervisor is a part of the HA cluster and can also process ﬁles like the Primary Superviso and the MTUs in the cluster while performing the job of a Secondary Supervisor.

In an HA cluster, it is mandatory to attach an additional network interface for the EC2 that acts as Primary supervisor prior to installation. The private IP of this additional attached network interface should be used for communication (Ceritalk/Web UI). The private IP address of primary network interface (which is pre conﬁgured with an EC2) should be used for QCloud cluster communication.

When starting an HA cluster, the cluster units should be started in the following order:

1. Primary Supervisor

2. Secondary Supervisor

3. Media Test Units: these should be started one by one after both the Primary Supervisor a nd Secondary

Cloud level and EC2 level conﬁgurations required before installation of the HA cluster units

The following are the conﬁgurations that need to be in place before QCloud is installed on EC2 systems.

1. Deﬁne IAM role in the Amazon AWS Cloud console as follows:

a. In the console, get the IA

b. Create a new role using the “create new role” option in this page.

c. Select this newly created role and create a new policy for this role. For this, se

These lines set the permission for QCloud to attach and detach network interface which is required for the functioning of HA and access of web UI using the single Ceritalk IP address even after fail over.

{ "Version": "2012-10-17", "Statement": [ { "Action": [ "ec2:AttachNetworkInterface", "ec2:DetachNetworkInterface" ], "Effect": "Allow", "Resource": "*" } ] }

d. Click on “Apply Policy” button and this policy will now be displayed under the “Permissions tab”.

2. Create EC2 instances with the IAM role attached as follows:

a. After setting up the IAM role mentioned above, now the user should proceed to create EC2

instances required for the HA cluster. During the creation of the instance, an option is provided

for the user to select the IAM role. This will be a drop down control that will display all the conﬁgured IAM roles. The user should select the IAM role that has the above policy created in it and proceed existing instance if it is not attached during the creation of the instance. Hence, the IAM role with the mentioned policy has to be created before creation of the EC2 instance and attached to the EC2 during the creation of instance.

3. Create an external network interface and select IP addresses during the installation of the Primary Supervisor as follows:

a. The HA cluster requires at least 2 Network Interface Cards to be present on the system where

primary supervisor is installed before the start of the installation of QCloud. This second network interface card should be an externally added network interface after the creation of the EC2 instance and before starting QCloud installation on Primary Supervisor. While creating the external address for that network interface.

b. The inte

network interface card. The private IP address associated with this interface should be selected as the network interface for cluster formation during the installation of the QCloud Primary Supervisor in the Supervisor settings installation screen.

c. The private IP address associated with the externally attached network interface card should

be selected for the Ceritalk\web UI communication during the installation of QCloud primary supervisor in the Supervisor settings installation screen.

4. Update hosts ﬁle with IP Address and hostname combination as follows:

a. The IP address and h ostname combination have to be updated into the hosts ﬁle for the IP address

resolution during cluster formation. This detail of all the units in the cluster needs to be updated into the hosts ﬁle of primary and secondary supervisor. The details of primary and secondary supervisors need to be updated into the hosts ﬁle of all the MTUs. The hosts ﬁle is found in c: address and not the Ceritalk\web UI communication IP. This will be the IP address selected for cluster formation during the installation.

Administrator privileges on all the machines on which the QCloud software will be installed.

All of the systems with QCloud installed need to meet the minimum hardware speciﬁcations.

All of the cl same network (VPC) as the Supervisor unit. It is recommended that each cluster unit be conﬁgured with Static IP addresses.

All of the PCs in the cluster should be able to route to each other. The Supervisor unit and the Secondary Supervisor unit (in the case of an HA cluster) each need to be given a network name that is recognized and resolved by all of the units in the clus t er.

You should know the NetBIOS name of the Supervisor unit and the Secondary Supervisor unit and provide these when the installer of the other units in the cluster asks for the names of the Supervisor and Secondary Supervisor units.

Time synchronization between all the units in cluster must be maintained. For example, use an NTP server to synchronize the units in a cluster.

Clustering scenarios that may not work

Clusters may not work in the following scenarios:

If a Media Test Unit or Secondary Supervisor cannot resolve Supervisor host name.

In the case of an HA cluster, if the Supervisor can not resolve the host name of the Secondary

Supervisor and vice versa.

If the Supervisor does not have a host name or if the Supervisor has a host name with Japanese or Chinese characters.

If a network has another system with the same host name as the Supervisor (or Secondary Supervisor) system.

If the host name of the Supervisor (or Secondary Supervisor) changes after cluster installation.

If the htt

p port on the Supervisor is conﬁgured to a different port number after cluster installation. In this case, the property cerify.supervisor.httpport in the system.properties on the Media Test Units must be changed to the new port number.

If the http port on the Supervisor is conﬁgured differently than that of the Secondary Supervisor.

If the p

rivate IP addresses of any units in the cluster change after the installation. In this case, the

property cerify.jboss.bindaddress must to be changed to the current IP address.

case of a normal (non-HA) cluster, if the Supervisor has multiple network interfaces connected

In the to the same network and if DNS/WINS are not conﬁgured properly, troubleshoot this problem by adding an entry containing the Supervisor host name and the IP address used by QCloud on Supervisor in "hosts" ﬁle, which can be found in

C:\WINDOWS\system32\drivers\etc in all the Media

Test Units.

System installation

This section provides details of hardware, software and user prerequisites for the system and instructions on performing the software installation.

Prerequisites

Hardware prerequisites

QCloud is designed to be run on a variety of hardware. Consequently, the choice of hardware is determined by performance and throughput requirements for your installation.

This section recommends hardware conﬁguration for some situations in which QCloud is typically used.

QCloud can be installed as either of the following two conﬁgurations on a given computer:

QCloud c performance requirements that are expected from such installations, it is recommended that server class hardware and operating systems be used in such cases.

In addition to the throughput required, the hardware requirements also depend heavily on the mode of operation that will be used. QCloud can operate in two modes:

The mode of operation that applies to your QCloud installation depends on the ﬁle formats you would like

test and other work ﬂow and connectivity related constraints that might apply to your situation. See the

Modes of Operation

he functional differences between these two modes of operation impact primarily on the disk space

T availability and disk conﬁguration requirements. Speciﬁcally, the copying mode requires a greater amount of disk space and high levels of concurrent read/write performance from the hard drives in order for best overall performance while the streaming mode can derive comparable overall performance with a lesser amount of disk space and lower read/write efﬁciency.

and

(see page 273) for a detailed discussion on the factors that inﬂuence this.

The general guidelines that should be followed when selecting hardware are:

Processor: 3 GHz

QCloud is capable of using as many processor cores as available for improved processing performance. While the minimum required conﬁguration is 1 core per channel, for optimum performance, it is

recommended to allocate between 4 and 6 processor cores per QCloud channel. It is also recommended that for best performance, you choose as much on-chip memory cache as possible.

NOTE. QCloud i Intel based server platform.

Memory:

It is recommended to use a minimum of 4 GB of RAM per channel and an additional 4 GB for the operat recommended memory therefore is: 4 x 4 GB (per channel) + 4 GB = 20 GB. W he n the expected load in QCloud is likely to be largely composed of huge media ﬁles, more memory per channel may be necessary.

Hard disk drive:

It is recommended to conﬁgure 500 GB of EBS storage for QCloud to work optimally. The installation of QCloud should be done on this EBS storage where the QCloud database also resides.

The amount of additional storage you need depends on the mode of operation that applies to your installation, the average size of the ﬁles you will be processing and the number of simultaneous ﬁles being processed. It does not need to be persistent storage, so you can use EC2's Ephemeral Storage when it is available.

Streaming mode

Due to the minimal hard disk utilization when operating in the streaming mode, it is sufﬁcient to provide a disk space of 100 GB in size as temporary storage for QCloud.

s optimized for Intel processor architectures, and therefore it is recommended to use an

ing system and the QCloud database. For optimum performance for 4 channels, the

Copying mode

The minimum disk space provided must be greater than the average ﬁle size being processed multiplied by the number of channels.

Network interface: 1 Gbit/s

Supported platforms

Windows Server 2008 64-bit

Windows Server 2008 R2 64-bit

NOTE. QCloud is expected to operate correctly on other variants of Windows as well, but it has been qualiﬁed only on the ones speciﬁed above.

Software inst

Before installing Q Cloud, you should be aware of the following information:

It is recommended that the QCloud application be installed on a machine where it can be used as the sole running application. QCloud makes intensive use of both CPU and memory and will considerably degrade the p services simultaneously will degrade the performance of QCloud and increase the time taken to process a media ﬁle.

QCloud relies on third-party software applications that are packaged and installed with it: JBoss and MySQL. If these applications are already used on the computer, you should remove them before attempting to install the QCloud.

QCloud uses a number of network services that are local to the host computer. These services can sometimes be blocked by personal ﬁrewall software, in which case an error message will be displayed when QCloud starts.

In such situations, conﬁgure the ﬁrewall to allow the service on the appropriate port, or alternatively disable the ﬁrewall entirely.

An installation log is written to the "%userproﬁle%\QCloud\QCloudInstallationLogs_<Timestamp>" folder. T his log gives details of selections you made during t he install and any errors encountered in case of failure to install.

QCloud should be installed on a EBS location.

While choosing the location for storing temporary video ﬁles during installation, make sure that thereissufﬁcient free space in this folder to store large video ﬁles. EC2's Ephemeral Storage can be used to store temporary video ﬁles.

QCloud uses the computer name (as stored in the environment variable named "COMPUTERNAME") to uniquely identify some of its network services. This will not work if non-ASCII characters are

ed in the computer name.

QCloud will fail to run if any other Web services using port 80 are running on the system where the

Cloud is installed (for example, the IIS Admin service, Skype or Apache). You can run QCloud once

Q you shut down the other port 80 services running on the system. Alternatively, you can conﬁgure the QCloud Web port to use a port other than 80.

It is not possible to install a lower version of QCloud when you have a higher version of QCloud already installed. For example, if you install QCloud version 7.7 and then you want to go back to QCloud version 7.6, you will need to ﬁrst uninstall QCloud 7.7 and then install QCloud 7.6.

Installing QCloud

The installation of the QCloud application takes several minutes; typically between 3 and 5 minutes depending on the speed of your computer.

CAUTION. To prevent installation problems, be sure to read about the known installation limitations.
