QCloud Quick Start User Manual i

Preface

Preface

QCloud is an automated system for testing compressed digital media before transmission or use. Through a Web-based
interface, you can create a Job, which will perform a sequence of checks on a set of media files, and view the results. This
manual provides installation instructions and a high-level operational overview of this product.

Product description

This is a med

any network connected workstation.

System co

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-contai ned 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.

Networking

EC2s (Elastic Computing Clouds) are systems on AWS Cloud. In a clustered configuration, EC2s should be part of a VPC
(Virtual Private Cloud). In a clustered configuration, network interface on all of the units, including the Supervisor, secondary
Supervisor (HA cluster only) and Media Test Units, should be should be part of the VPC (Virtual Private Cloud). This
connection is used to access media files, to service Web clients, and to carry cluster control traffic.

loud, the following configurations are required for a QCloud enterprise cluster to function:

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 external 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

rity” section. This will list down all the available security groups. Note that this list displays the “Group Id” for each of the

Secu
security groups. Select the security group to be updated with the rules. T he lower panel will display the security group details.

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

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 gr oup. 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 traffic from the EC2 to the outside.

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, due to a m achine crash), the 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 will 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 Supervisor 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 and Secondary Supervisor are

started

QCloud Quick Start User Manual v

Preface

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 IAM dashboard.

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, select the new role created above and

click on Attach Role Policy button at the bottom of the dashboard. In the UI that comes up, select “Custom Policy”
option and click on Select next to it. In the Set Permissions window, enter a name for this policy and copy the
below lines in the “Policy D ocument” text box.

These lines set the permission for QCloud to attach and detach network interface w hich 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", "S tatement": [ { "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 creating the EC2 instance. Please note: The IAM role cannot be attached to
an 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 network interface, it is possible to assign an IP address of your choice as
private IP address for that network interface.

b. The interface that comes along with the EC2 instance during EC2 creation is called the primary 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 hostname 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:\windows\system32\drivers\etc folder. Please note: This should be the
cluster formation IP address and not the Ceritalk\web UI communication IP. This will be the IP address selected
for cluster formation during the installation.
