CDN and clustering in GNU/Linux with performance testing
Mikulka, Pavel ; Pelka, Tomáš (referee) ; Šimek, Milan (advisor)
Fault tolerance is essential in a production-grade service delivery network. One of the solution is build a clustered environment to keep system failure to a minimum. This thesis examines the use of high availability and load balancing services using open source tools in GNU/Linux. The thesis discusses some general technologies of high availability computing as virtualization, synchronization and mirroring. To build relatively cheap high availability clusters is suitable DRDB tool. DRDB is tool for build synchronized Linux block devices. This paper also examines Linux-HA project, Redhat Cluster Suite, LVS, etc. Content Delivery Networks (CDN) replicate content over several mirrored web servers strategically placed at various locations in order to deal with the flash crowds. A CDN has some combination a request-routing and replication mechanism. Thus CDNs offer fast and reliable applications and services by distributing content to cache servers located close to end-users. This work examines open-source CDNs Globule and CoralCDN and test performance of this CDNs in global deployment.

SaaS IT helpdesk - Innovating conception of IT helpdesk
Andrle, Tomáš ; Pour, Jan (advisor) ; Mikulka, Pavel (referee)
This bachelor thesis is focused on information systems, which purpose is to support business processes of IT Helpdesks. The first part is analytical. Possibility of practical usage in varying organizational specifications (size, scope of business, etc.) is critically evaluated by examples and characteristics of product variants available on the market. An important aspect of deployment and operation of IT helpdesk proved to be a problem providing human and infrastructure resources. End of this part motivationally summarizes nowadays shortcomings of current conceptions of IT helpdesk information systems. The second part, which is the main contribution of this thesis and is the original part, comes to unravel problems of the analysis. The solution consists in the innovative concept of the IT helpdesk, which would be available to the public without need of upfront investments, and which would operate as a distributed service model according to the principles of Software as a Service (SaaS). The new concept offers series of procedural and implementing improvements to centralize it in one consolidated unit. The concept illustrates the map of functional components and abstracted operating environment of potential product. The conclusion of the original part of work is devoted to motivational site of this concept, where possible valuation method of potential service is introduced. The work aspires to become a manual for developers of similar solutions, who can draw on the rich experience of the author and reflect written images of "ideal" SaaS IT helpdesk into real commercial products.

Server driven negotiation
Mikulka, Pavel ; Kastl, Jan (advisor) ; Pinkas, Otakar (referee)
Práce přibližuje základy protokolu HTTP a možnosti využití dynamického zasílání www stránek. První kapitola popisuje protokol HTTP na obecné úrovni, druhá se věnuje dynamicky zasílaným stránkám. Přínosem je ukázka implementace na dvou prakticky využitelných aplikacích. První z nich je automatický rozcestník pro webové sídlo, jehož úkolem je přesměrovat uživatele na nejvhodnější jazykovou verzi v závislosti na hodnotě hlavičky Accept-Language nebo IP adrese a druhou je download platforma pro společnost nabízející zábavní obsah pro mobilní telefony, jež poskytuje uživateli optimální verzi obsahu v závislosti na user-agent hlavičce jeho přístroje.
