Amazon EC2 offers the CloudWatch service to monitor cloud instances as well as load balancers. While this service comes at some cost (0,015$/hour/instance) it offers useful infrastructure metrics about the performance of your EC2 infrastructure. While there are commercial and free tools out there which provide this service, you might not want to invest in [...]

Because virtual machines work by time-sharing host physical hardware, a virtual machine cannot exactly duplicate the timing behaviour of a physical machine. This leads to the timekeeping problems explained in the VMWare White Paper about Timekeeping in Virtual Machines that results in inaccurate time measurements within the virtual machine. This affects ALL performance metrics that rely [...]

I already listened to a couple of talks on the cloud. The whole cloud topic start to grow up, meaning more and more application scenarios for the cloud are appearing.
Yesterday there was a very useful classifcation of cloud services. The differentiated cloud services at a couple of different levels.

Infrastructure as a Service – providing computing [...]

In this blog – Challenges of Monitoring, Tracing and Profiling your Applications runing in “The Cloud” -I discussed the challenges of monitoring, tracing and profiling applications running in the Cloud. This blog describes an approach of how to solve those challenges with dynaTrace in a GigaSpaces Cloud Environment.
The GigaSpaces Cloud Environment
The application, acting as the IMDG [...]

Cloud Computing presents unique opportunities to companies to reduce costs, outsource non-core functions and scale costs to match demand. However, the Cloud also presents a new level of complexity that makes ensuring application performance in the Cloud a unique challenge, in particular  with the many different usage and deployment scenarios available. Perhaps the most popular [...]
