Chapter 15. Amazon Web Service Interface

4.(Optional) The AWS API listens for requests on port 7080. If you prefer AWS API to listen on another port, you can change it as follows:

a.Edit the files /etc/cloudstack/management/server.xml, /etc/cloudstack/management/server- nonssl.xml, and /etc/cloudstack/management/server-ssl.xml.

b.In each file, find the tag <Service name="Catalina7080">. Under this tag, locate <Connector executor="tomcatThreadPool-internal" port= ... >.

c.Change the port to whatever port you want to use, then save the files.

d.Restart the Management Server.

Note

If you re-install CloudPlatform, you will have to make these changes again.

15.4. AWS API User Setup Steps (SOAP Only)

In general, users need not be aware that they are using a translation service provided by CloudPlatform. They need only send AWS API calls to CloudPlatform's endpoint, and it will translate the calls to the native API. Users of the Amazon EC2 compatible interface will be able to keep their existing EC2 tools and scripts and use them with their CloudPlatform deployment, by specifying the endpoint of the management server and using the proper user credentials. In order to do this, each user must perform the following configuration steps:

Generate user credentials and register with the service.

Set up the environment variables for the EC2 command-line tools.

For SOAP access, use the endpoint http://CloudPlatform-management-server:7080/awsapi. The CloudPlatform-management-servercan be specified by a fully-qualified domain name or IP address.

15.4.1. AWS API User Registration

Each user must perform a one-time registration. The user follows these steps:

1.Obtain the following by looking in the CloudPlatform UI, using the API, or asking the cloud administrator:

The CloudPlatform server's publicly available DNS name or IP address

The user account's API key and Secret key

2.Generate a private key and a self-signed X.509 certificate. The user substitutes their own desired storage location for /path/to/… below.

$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /path/to/private_key.pem -

out /path/to/cert.pem

3.Register the mapping from the X.509 certificate to the API/Secret keys. Download the following script from http://download.cloud.com/releases/3.0.6/cloudstack-aws-api-registerand run it. Substitute the values that were obtained in step 1 in the URL below.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
