Cloud Computing

By Bastian Schäffer, 2008

Cloud Computing is an emerging trend in the mainstream IT world. 52°North has worked extensively in this field in order to combine classical Geospatial Web Services with this new Paradigm. Scalability was a prime goal here for mastering massive requests and peak loads. The following figure shows the response time on a local machine:


Web Geoprocessing Service (WPS) in the Cloud

The 52°North WPS was successfully installed out-of-the box on the following public cloud environments:
  • Amazon Web Services (AMI available on request, see this {{{}tutorial}})
  • Google App Engine
and the following private/hybrid cloud environments:
  • Eucalyptus
A practical example can be seen in the INSPIRE compliant Coordinate Transformation Service depicted in the following figure:


The response time could be held nearly constant even during peakloads as shown in the figure below.


Web Map Service in the Cloud

Web Map Services (WMS) often have to deal with a large number of requests. In order to handle peak loads, a solution was created which utilizes a WMS (Geoserver) in a cloud environment (public cloud: Amazon, private cloud: Eucalyptus).

The following figure shows OSM streetdata for Germany served by a WMS in the cloud. The rendering of tiles could be massively improved and the response time even during peak load held constant.


Hybrid Cloud

As a third opton, we provide solutions for a hybrid cloud by “cloudifying” local IT resources to private clouds and using public clouds (such as Amazon Web Services) for peak loads. A reference architecture entirely composed of open-source components was created as depicted in the figure below.


Our own Cloud Management software for monitoring and ruleset defining is available as open-source in our repository.

A constant response time was reached even during peak loads.
