As the services offered by General Directorate of the Social Assistance and Solidarity (GDSAS) expand, it is needed to revise the infrastructure of the institution. Within the scope of these needs, studies have been done to find a solution to secure client / server infrastructure, to shorten and standardize the problem solving process.
In order to respond quickly to the increased needs of capacity, to minimize the disruption time and to use the idle capacity, all systems of the GDSAS were put into virtual environment. There are critical software web servers and application servers such as MS SQL 2005, MS Exchange 2007, MS Active Directory, MS SQL and MS Exchange and also open-source operating system UBUNTU running and moving between virtual servers. Using this system, GDSAS is able to serve more than 5.000 users with high performance.

Technology solution
In order to respond quickly to the increased needs of capacity, to minimize the disruption time and to use the idle capacity, all systems of the GDSAS were carried in to virtual environment. There are critical software web servers and application servers such as MS SQL 2005, MS Exchange 2007, MS Active Directory, MS SQL and MS Exchange and also open-source operating system UBUNTU running and moving between virtual servers. Using this system, GDSAS is able to serve more than 5.000 users with high performance.
In the virtualization process existing applications are installed after their security and performance policies are revised and upgraded to the latest versions. The virtualization provided decreases the cost of infrastructure and maintenance and increases the level of accessibility and usage of the RAM and CPU capacity. There are 10 virtual servers in a single cabinet and it is more manageable than 10 physical cabinets.
HA (High Availability) and DRS (Dynamic Scheduling of Resources System) solutions are being used effectively with virtualization. Thus efficient use of the resources and performance improvement has been achieved.
Technology choice: Standards-based technology, Open source softwareMain results, benefits and impacts
The used capacity of RAM, CPU are increased.
The cost of infrastructure and maintenance is decreased.
10 cabinets were unified in a single cabinet, hence management became easier.
The other 9 cabinets were given to the other institutions that are sharing data with SYDGM in SAIS
or Integrated Social Services Project.
The problem-solving process in Server/Client infrastructure is standardized and shortened.
More reliable Server/Client infrastructure is created. Security is redesigned.
With the backup feature, consistency is maintained.
For more than 5 thousand users performance is increased.
Return on investment
Return on investment: Not applicable / Not availableLessons learnt
It is more efficient to use virtual servers than physical servers. Maintenance for a virtual structure is easier than for a physical structure. Since the physical hardware is reduced, electricity usage is decreased.
With the use of HA (High Availability) and DRS (Dynamic Scheduling of Resources System) solutions, the used capacity of RAM and CPU is increased.
