We live in a world that is constantly evolving where new technologies and innovations are being introduced. This progress partly results in developing new technologies and also in the improvement of the current ones. Docker containers are a virtualization method that is one of these new technologies that has become a hot topic around the world as it is said to be a better alternative to today's current virtual machines. One of the aspects that has contributed to this statement is the difference from virtual machines where containers isolate processes from each other and not the entire operating system. The company Saab AB wants to be at the forefront of today's technology and is interested in investigating the possibilities with container technology. The purpose with this thesis work is partly to investigate whether the container solution is in fact an alternative to traditional VMs and what differences there are between these methods. This will be done with the help of an in-depth literature study of comperative studies between containers and VMs. The results of the comparative studies showed that containers are in fact a better alternative than VMs in certain aspects such as performance and scalability and are worthy for the company. Thus, in the second part of this thesis work, a proof of concept implementation was made, by recreating a part of the company’s subsystem TactiCall into containers, to ensure that this transition is possible for the concrete use-case and that the container solution works as intended. This task has succeeded in highlighting the benefits of containers and showing through a proof of concept that there is an opportunity for the company to transition from VMs into containers.

There currently does not exist a way for creating digital twins’information and transferring it between networks , but container-basedvirtualization could be a possible solution. One of those techniques isDocker, which is an engine to isolate a software and can bring benefits toimprove the workflow of software development. Making changes withDocker is very fast as it uses the copy-on-write model, it can containerizeapplications in minutes. This study will design a scenario with twodevices sending a data packet between each other to simulate theproblem. The results from the study is further investigate and analyze toanswer the question of whether the container-based virtualization can bea possible solution for creating digital twins. The result from the scenariois Docker works equal or worse when used with a low-cost computinghardware compared to a computing hardware. It is speculated that theresources used in the images is a factor that can affect the performance,but the hardware is also another factor that can affect it. / Det finns för närvarande inget sätt att skapa digitala tvillingar ochöverföra den mellan nätverk, men containerbaserad virtualisering kanvara en möjlig lösning. En av containerbaserad virtualisering tekniker ärDocker, som är en motor för att isolera en programvara och kanframbringa fördelar för att förbättra arbetsflödet för programutveckling.Att göra ändringar med Docker är mycket snabbt tack vare användningav copy-on-write-modellen. Denna studie kommer att utforma ettscenario med två enheter som skickar ett datapaket mellan varandra fratt simulera överföringsprocessen. Mätresultat från studien bliranalyserad för att besvara frågan om containerbaserad virtualisering kanvara en möjlig lösning för att skapa och skicka digitala tvillingar.Resultatet från scenariot är att Docker fungerar lika eller sämre när detanvänds med en låg kostnad datorhårdvara jämfört med endatorhårdvara. Det spekuleras att resurserna som används i datapaketetär en faktor som kan påverka prestandan, men hårdvaran är också enannan faktor som påverkar det.

Diploma thesis deals with creating the concept of container based modular building. The process of building is made by connecting module. Three block modules were designed. They could be created up to nine combinations (Up to nine combination might be created up by these). The modules are designed as a diffuse open wooden building with a warm flat roof. Family house is one of the possible combinations. Construction of building consists of two connected modules that are made like single-storey. Founded on earth screws. Under the construction is ventilated space. The building is situated on flat land (parcel) in Velké Němčice. The advantages of modular container buildings are good thermal properties, short time of construction and the possibility of connecting or disconnecting the modules.
