Decommissioning-as-a-Service – IT cost optimisation through optimised server capacities

Identify unused servers and reduce IT costs
  •€ are wasted by companies worldwide each year on cloud services they don't need
  • 360 kg of CO2 are generated by a single server every year
  • 30% of servers in data centres are unused servers

Unused servers can be expensive – and identifying them is a challenge

Many companies, regardless of industry, face a similar challenge: the server infrastructure has historically continued to grow, which leads to unnoticed unused servers and sometimes makes the system landscape difficult to keep track of. This leads to the fact that there is a lot of unused server capacity that could be discontinued. However, these unused servers are difficult to identify and only with a great deal of effort. At the same time, they cause immense and, above all, unnecessary running costs - for example, through cloud subscriptions, maintenance work or the electricity costs for running the servers.


The server landscape of some companies is not analysed carefully enough before migrating to a new system. Old errors are transferred to the new system and the server landscape becomes increasingly opaque.


Due to the interaction of these aspects, the server operation costs are constantly rising. Accordingly, there is a need for IT cost optimisation.


Many unused servers are also accompanied by high ecological costs, because many operating servers inevitably also mean enormous power consumption. The CO2 balance of your company can therefore be negatively affected as well.

Decommissioning-as-a-Service – Our solution for the identification and decommissioning of unused servers

With Decommissioning-as-a-Service, PwC supports you specifically in the partial decommissioning of your unused IT. Decommissioning-as-a-Service is PwC's end-to-end tool that identifies the unused servers and then comprehensively supports the decommissioning process together with our experts. The final decommissioning is then carried out by your IT department or IT service provider. Our solution recognises redundant servers with the help of a specially developed, innovative artificial intelligence. This saves you unnecessary server capacity and thus power consumption and electricity costs. 
So you give something back to your wallet and the next generation!

The AI only needs to be fed with the monitoring data of the server landscapes. After this analysis phase, the results are evaluated in cooperation with the customers. Through process support, time-consuming evaluation and decision-making processes that would normally be required for such a consultancy service are accelerated by Decommissioning-as-a-Service

With Decommissioning-as-a-Service in 3 steps to success

No Decommissioning-as-a-Service project is the same. We make sure that you get the perfect solution. That's why our services are always tailored to our customers. 
Generally, Decommissioning-as-a-Service can be divided into three phases.

1. Discovery-and-Assessment Phase

Our team checks the monitoring data and prepares it in the right form for the process in a comprehensible and transparent way. Based on the prepared data, the so-called artificial intelligence training takes place. Once the training is complete, the actual analysis of the IT landscape is carried out to identify unused systems. As a result, the AI creates a candidate list for unused servers that can be decommissioned.

2. Test Phase

The list of candidates to be decommissioned is then reviewed by the project team and the client. Under certain circumstances, an inspection of individual systems takes place. The savings potential is evaluated and the systems are subjected to the so-called "scream test". This "scream test", which evaluates whether all servers are really unused, is carried out either by the client or the client's service provider.

3. Realisation Phase

The systems that have been subjected to a screen test are finally decommissioned if the test is successful. There is a standardised process in place at this point, which is accompanied by PwC. This process ensures that all necessary documents are available and that the system actions are carried out in the correct order. This way, all remaining requirements can be fulfilled.

How can unused servers be identified?

Unused servers are often characterised by deviating workload patterns. Used systems often have seasonal and recurring workload patterns. One such recurring pattern is, for example, non-existent utilisation at the weekend. Unused systems often have a permanently very low load level with few fluctuations.

Is the tool also suitable for tidy and clear server landscapes?

Yes! The tool is suitable for every landscape. In such cases, the risk-and-reward model is recommended. This is because additional costs are only incurred if unused servers are found and decommissioned. Our consultants provide transparent and professional support in the complete optimisation of server performance.

Who decommissions the unused servers?

PwC supports your company and all employees in the orchestration process. The partial decommissioning of your IT is then carried out by your own IT department after detailed preparatory planning.

Can the tool be combined with other monitoring tools?

Data protection plays a prominent role at PwC and this is of course also uncompromisingly guaranteed in connection with Decommissioning-as-a-Service.


Therefore, linking to a monitoring tool is not allowed. The data is uploaded anonymously to our tool and we guarantee that no personal data is stored on PwC servers.


How does PwC ensure that only servers that are actually unused are switched off?

After identifying a potentially unused system, a visual inspection of the system often takes place to substantiate the assumption. If the impression gained by a system administrator is confirmed, we carry out a so-called 'scream test'. This involves a coordinated and temporary shutdown of the system to check whether there are messages from users via central message channels. These include, for example, the IT hotline or other downtime services. If there are no messages within a two to four week time window, then we can determine with a very high degree of certainty that the server is indeed unused.
