Technical Report
Full-text available
The project CloudTRANSIT dealt with the question of how to transfer cloud applications and services at runtime without downtime across cloud infrastructures from different public and private cloud service providers. This technical report summarizes the outcomes of approximately 20 research papers that have been published throughout the project. Thi...
Conference Paper
Full-text available
Cloud-native applications are intentionally designed for the cloud in order to leverage cloud platform features like horizontal scaling and elasticity-benefits coming along with cloud platforms. In addition to classical (and very often static) multi-tier deployment scenarios, cloud-native applications are typically operated on much more complex but...

Conference Paper
Full-text available
Elastic container platforms (ECP) like Docker Swarm, Kubernetes (k8s) and Apache Mesos have gotten more and more attention by practitioners in recent years [1]. Elastic container platforms fit very well with existing cloud-native application (CNA) architecture approaches [6]. Corresponding system designs often follow a microservice-based architectu...
Conference Paper
Full-text available
Due to REST-based protocols, microservice architectures are inherently horizontally scalable. That might be why the microservice architectural style is getting more and more attention for cloud-native application engineering. Corresponding microservice architectures often rely on a complex technology stack which includes containers, elastic platfor...

Cloud computing enables companies getting computational and storage resources on demand. Especially when using features like elasticity and scaling, cloud computing can be a very powerful technology to run, e.g., a webservice without worries about failure by overload or wasting money by paid use of unneeded resources. For using these features, deve...
Article
Full-text available
It is common sense that cloud-native applications (CNA) are intentionally designed for the cloud. Although this understanding can be broadly used it does not guide and explain what a cloud-native application exactly is. The term "cloud-native" was used quite frequently in birthday times of cloud computing (2006) which seems somehow obvious nowadays...
Chapter
Full-text available
Cloud computing enables to deliver innovative services very agile and at world-scale. Even very small companies with access on first class cloud engineering knowledge can create exponential business growth. Companies like Instagram or Netflix proofed that impressively. But, operating cloud-native applications is extremely challenging and overburden...
Conference Paper
Full-text available
Companies like Netflix, Google, Amazon, Twitter successfully exemplified elastic and scalable microservice architectures for very large systems. Microservice architectures are often realized in a way to deploy services as containers on container clusters. Containerized microservices often use lightweight and REST-based mechanisms. However, this lig...
Conference Paper
Full-text available
Container clusters have an inherent complexity. A distributed container application in the cloud can be complex at planning, installation and configuration, maintenance and search for failures. Small and medium enterprises (SMEs) are mostly limited by their personnel and financial restrictions. Using advanced cloud technologies like a container clu...
Article
Full-text available
In previous work, we concluded that container technologies and overlay networks typically have negative performance impacts, mainly due to an additional layer to networking. This is what everybody would expect, only the degree of impact might be questionable. These negative performance impacts can be accepted (if they stay moderate), due to a bette...
Article
Full-text available
Cloud service selection can be a complex and challenging task for a cloud engineer. Most current approaches try to identify a best cloud service provider by evaluating several relevant criteria like prices, processing, memory, disk, network performance, quality of service and so on. Nevertheless, the decision making problem involves so many variabl...

Project
All project results can be found here: https://cosa.fh-luebeck.de/en/cloud/projects/cloud-transit Current state of the art cloud based software services are often characterized by a highly implicit technological dependency on underlying hosting cloud infrastructures. The project Cloud TRANSIT investigates, how to design cloud based software services to reduce technological dependencies on underlying cloud infrastructures. By designing and developing a generic cloud service description language, it should be possible to define secure, transferable and elastic services of typical complexity being deployable to any IaaS cloud infrastructure. Furthermore, it should be possible to migrate these services from one private or public cloud infrastructure to another (not necessary compatible) cloud infrastructure. This kind of transferability reduces cloud infrastructure related technical vendor lock-in problems for small and medium sized enterprises.
