Abstract:

Container technology has gained popularity in recent years, mainly because it enables a fast and easy way to package, distribute and deploy applications and services. Latency and throughput have a high impact on user satisfaction in many real-time, critical and large-scale online services. Although the use of microservices architecture in cloud-native applications has enabled advantages in terms of application resilience, scalability, fast software delivery and the use of minimal resources, the packet processing rates are not correspondingly higher. This is mainly due to the overhead imposed b

Abstract:

Container technology continuously grows in popularity, and the forensic area is less explored than other areas of research concerning containers. The aim of this thesis is, therefore, to explore Docker containers in a forensic investigation to test whether data can be recovered from deleted containers and how malicious processes can be detected in active containers. The results of the experiments show that, depending on which container is used, and how it is configured, data sometimes persists after the container is removed. Furthermore, file carving is tested and evaluated as a useful method

Abstract:

Containers have been gaining popularity in recent years due to their ability to provide higher flexibility, higher reliability and dynamic scalability to enterprise software systems. In order to fully utilize containers, software developers aim to build their software using microservice architecture, meaning that instead of working on a single large codebase for the whole project, the software is split into smaller units. These microservices can be deployed in their own container instead of the traditional virtual machine setup where a server has to configured with all necessary dependencies.

Abstract:

Designing an application from top to bottom is a challenge for any software architect. Designing an application to be deployed in the cloud adds extra complexity and a variety of questions to the task. One of these questions is how to deploy an application? The most popular choices at this time are either Docker containers or serverless functions. This report presents a comparison between the two deployment methods based on cost and performance. The comparison did not yield a conclusive winner but it did offer some key pointers to help with the decision. Docker containers offer a standardized

Abstract:

Software containers in general and Docker in particular is becoming more popular both in software development and deployment. Software containers are intended to be a lightweight virtualization that provides the isolation of virtual machines with a performance that is close to native. Docker does not only provide virtual isolation but also virtual networking to connect the isolated containers in the desired way. Many alternatives exist when it comes to the virtual networking provided by Docker such as Host, Macvlan, Bridge, and Overlay networks. Each of these networking solutions has its own a

Abstract:

A new promising technology to face the problem of scalability and availability is the microservice architecture. The problem with this architecture is that there is no significant study that clearly proves the performance differences compared to the monolithic architecture. Our thesis aims to provide a more conclusive answer of how the microservice architecture differs performance wise compared to the monolithic architecture. In this study, we conducted several experiments on a self-developed microservice and monolithic system. We used JMeter to simulate users and after running the tests we lo

Abstract:

Service assurance is critical for high-demand services running on telecom clouds. While service performance metrics may not always be available in real time to telecom operators or service providers, service performance prediction becomes an important building block for such a system. However, it is generally hard to achieve. In this master thesis, we propose a machine-learning based method that enables performance prediction for services running in virtualized environments with Docker containers. This method is service agnostic and the prediction models built by this method use only device s

Abstract:

Il numero di dispositivi IoT connessi alla rete è in costante aumento e con loro i dati da essi prodotti. Le tradizionali soluzioni di elaborazione e archiviazione dati non saranno più sufficientemente performanti in quanto la mole di dati crescerà in maniera esponenziale nei prossimi anni. Nuovi approcci spingono all'introduzione di uno strato intermedio tra il creatore del dato e il luogo dove deve essere depositato, uno di questi approcci è l'Edge computing; ma la gestione dei servizi in esecuzione al suo interno rappresenta una nuova sfida. Nella distribuzione di servizi si stanno evolvend

Abstract:

The goal of this research is to create a methodology that evaluates the security posture of container images and helps improve container security. This was done by first searching for any guidelines or standards that focus on container images and security. After finding none, I decided to create an evaluative methodology. The methodology is composed of actions that users should take to evaluate the security of a container image. The methodology was created through in-depth research on container images and the build instructions used to create them and is referred to as the Security Evaluation

Abstract:

Setting up one's software environment and ensuring that all dependencies and settings are the same across the board when deploying an application, can nowadays be a time consuming and frustrating experience. To solve this, the industry has come up with an alternative deployment environment called software containers, or simply containers. These are supposed to help with eliminating the current troubles with virtual machines to create a more streamlined deployment experience.The aim of this study was to compare this deployment technique, containers, against the currently most popular method, vi

Abstract:

As IT platforms grow larger and more complex, so does the underlying infrastructure. Virtualization is an essential factor for more efficient resource allocation, improving both the management and environmental impact. It allows more robust solutions and facilitates the use of IaC (infrastructure ascode). Many systems developed today consist of containerized microservices. Considered the standard of container orchestration, Kubernetes is the natural next step for many companies. But how do we move on from previous solutions to a Kubernetes cluster? We found that there are not a lot of detailed

The Information and Communication Technology (ICT) industry and network researchers use traffic generator tools to a large extent to test their systems. The industry uses reliable and rigid hardware-based platform tools for high-performance network testing. The research community commonly uses software-based tools in, for example, experiments because of economic and flexibility aspects. As a result, it is possible to run these tools on different systems and hardware.
