Autonomic Resource Management using Drools

Rules help to autonomically govern Cloud infrastructures. In this post we will see how we can formulate rules in Drools to configure the virtual machines in the Cloud – using the speculative approach from my last post. Re-configuring VMs to save energy Last time we saw that dynamically resizing virtual machines (VMs) in terms of CPU power, memory, storage, or bandwidth could help to save energy. Why? Because the smaller Continue reading

Speculating about resource consumption

from on 09.09.2013

Speculation is not only something for banks, but can also help to save energy. May it be a little bit less? When renting a virtual machine (VM), we set up a QoS contract between the Cloud provider and the customer that specifies details about how “large” the VM should be. These contracts are called Service Level Agreements (SLAs). Violations of terms in these SLAs result into penalties the Cloud provider Continue reading

Continuous Delivery in the Cloud

from on 15.08.2013

Continuous delivery has become one of the most popular software patterns in recent years. It changes much of the way we are thinking about software. There is no plan for the release next may. There are features that will be in production tomorrow, or at least in a week. Internet companies like flickr or amazon are proud to delivery new features constantly (e.g. amazon claims to release a new feature every 11.6 seconds). Let’s see how cloud computing is a perfect fit for implementing continuous delivery. Continue reading

Big Cloud for Small Apps

Most people associate cloud computing with large global auto-scaling applications. However, there is a different kind of applications that substantially benefit from cloud computing: small applications, like rapid prototypes or small business supporting systems. Running small applications in the cloud brings a number of benefits over a traditional in-house operations model. These include fast availability, new cost models and simple extensibility.

Saving Energy and Resources Through Cloud Computing

Energy-efficient clouds

Dealing with energy wisely is a cross-cutting challenge worldwide, also for IT, and especially for Cloud Computing. I finished my PhD at TU Vienna last year addressing exactly this issue. How can we save energy in Clouds, while guaranteeing a high service quality at all times? Will IT destroy the environment? ICT makes up for 2% of the worldwide CO2 production – and rising. This might not seem much, but Continue reading
