Infrastructure Consolidation Project
In the Ministry Public Administration and Justice, in year 2009

Executive summary
With the implementation of Microsoft Hyper-V R2 in the Ministry of Public Administration and Justice the organization saved and continues to save at least 4.5 Million Ft1 yearly in a five year period, with minimal investment, leveraging modern technologies and procedures and with having added values like high availability. Since the Project became a Microsoft Case Study2 the aforementioned financial and technological benefits augmented with PR values, as it is set as an example of the efforts of the efficient e-government and referred several times. As of my participation, I Initiated, planed, led, the project and after the successful delivery promoted internally and externally the achievement.

Background
In 2009 most of the Ministries Server side Infrastructure was outdated, there where performance issues, server malfunctions and other difficulties caused by the 7-9 year old equipment. The problems have been known for years, but due to the limited budget the modernization of the whole infrastructure, a one to one replacement where out of the question. Based on the previous experience in virtualization - mostly VMware, in test environment -, I believed that by introducing virtualization to the production environment most of the problems could be solved. In the meantime two major events have happened, first two extra servers - suitable for virtualization - where procured in conjunction with another project which eliminated founding difficulties and second there where news that Microsofts new offering will be a leap forward and will turn the tides in the virtualization market.

Preparation and Execution
Having the necessary prerequisites and the approval of middle management I initiated testing of Hyper-V R2 beta in server core flavor, as a personal side project in June. During the proof of concept phase thorough testing where made including stability by generating high load, resilience by simulating failure of the components, integration to the (backup) environment and conversion machines from Psychical to Virtual form. Documentation in general where checked by a senior system engineer of the local gold certified Microsoft partner and in particular the implementation script was checked in action by a fellow administrator. Bye the end of august everything was tested, verified and ready for the launch. This way two days after the final product was available, the beta version cluster was decommissioned and the new clustered hosting solution was implemented. As of the Psychical Virtual conversion we applied extra caution, the procedure started with the least important internal service follow by the more significant ones as time passed. The method for the conversion followed this pattern; maintenance was scheduled for the specific service on Wednesday for Friday afternoon out of business hours, the conversion happened during that time3, after words we closely monitored the behavior of both psychical and virtual servers. If conditions where suitable than the next scheduled downtime was initiated, and with it a new cycle of conversion started, at total seven times.

Added value and Influence
The detailed ROI calculation is available in the aforementioned case study, only to summaries the benefits of the change those are the following; decrease of energy and amortization costs, reduction of investments of network infrastructure and miscellaneous technological requirements (like remote KVM), reduction of software license cost, performance gain, high availability for every virtualized service, 50 % longer UPS hold time, and greener environment. Since the publication other branches of the government consulted with us in the meter, having elevated prestige and appreciation of the organization. It influenced further developments in a way that when a disaster recovery site was created a year later, it was entirely virtualized producing significant cost savings, on every level of the infrastructure. This wouldnt have been possible if virtualization had not been previously introduced so extensively. In a personal level I learned a lot thru this work, by experiencing management of the project and handling communication, and in a technological perspective consolidating multiple servers with Direct Attached Storage to a single SAN made me aware of storage optimization and performance testing need, resulting in deep understanding of storage characteristics.

1 Which is about 20 500$ at actual currency rates, which is a very conservative estimate, actual savings are 20 30% higher

3 If anything would have gone bad, there would have been the weekend to fix the problem without major business impact

Über mich

According to one of my letter of recommendation: "As of his character, generally he is good in problem solving, he has long-term perspective, and in the meantime he is hardworking and gets the job done. His knowledge of IT industry whether its Microsoft products, servers, storages or consumer electronics related, combined with his economics background makes him a good candidate for project related tasks, where he can focus on unstructured or semi structured problems, or possibly being an application owner where several different areas of business are involved. He is independent in his work, who only needs setting of priorities and time to time reviews."
