What is the general benefit of using PTV xServer?

PTV xServer have been designed to provide highly scalable components for developing customer specific (web) applications. The following list indicates the advantages of these products.

Simplicity of use

It should be as easy as possible for software developers to integrate the PTV xServer functionality into their application using standard technologies. Web services are key factors in this respect, since they are supported by most development and runtime environments. Hence, PTV xServer uses standard web service technologies to communicate with clients.

Performance

This is crucial to almost all applications using xServer. Therefore, the server should produce results in a minimum amount of time, while using the available resources in an optimised way. In order to provide the best performance, xServer consists of two parts - a Java part doing all communication, IO and process management required for integration and infrastructure and a high-performance native engine providing the efficient algorithms. To use system resources more efficiently, xServer may be split into separate processes which can be distributed in a multi-CPU environment - there is one process doing the communication and management and there may be several back-end processes doing the real work.

Scalability

PTV xServer has been designed for hosting environments where there is a lot of load, such as web farms and so on. In order to provide the best scalability, PTV xServer is usually designed as a stateless server. This means administrators can scale the throughput by using standard load-balancing technology. However, there are some special servers that need an in-memory state and a corresponding session context.

Simplicity of administration

If you have to deal with server farms, you need to easily analyse and manage components. xServer includes a web administration and monitoring interface. This means that administrators can easily monitor a server from a remote site. Additionally, it uses a configurable logging framework Log4J that can be extended to send log messages to almost any logging or event management infrastructure available in your environment, providing administrative events in case of failures. Configuration and logs can be managed from remote sites.

What is the benefit of using PTV xServer bundle?

PTV xServer bundle combines all PTV xServer modules in one running server. The following list indicates the advantages of both deployment scenarios.

Mixed service deployment

  • Improved hardware utilization: Balancing between different services (not all are used at the same time).
  • Synergy effects (increased maximum throughput for service mixes): Less cache misses and less pipeline conflicts during hyper-threading.

PTV xServer bundle

  • One port is used for all services.
  • Simplified deployment: One xServer installation per server.
  • Improved RAM utilization: One web server process is running for all services, memory for queues is shared between services.
What is the benefit of using PTV xServer internet?

PTV xServer internet comprises the PTV Group software component solutions hosted online in Microsoft® Windows® Azure. Besides the complete range of functions of PTV xServer, they also offer all the benefits of a software-as-a-service solution. The following list indicates the advantages of this product.

How to control user access by using PTV xServer

Despite PTV xServer is not designed to provide access control services and protection against unauthorised access, there is a simple but insecure mechanism to set up something like an access control list.

Configuration

Just create a configuration file named users.properties that consists of user/password pairs (both in plain text). When this is done, incoming HTTP requests are validated against that file. The corresponding values are matched against the properties file.

Important note

The request headers must contain the username and password fields. If you need to set up a more secure environment, you can make use of the enhanced authentication techniques that come with the web server, e.g. in order to use basic authentication.
