abstract = {Various technologies have been developed to automate the deployment of
applications. Although most of them are not limited to a specific
infrastructure and able to manage multi-cloud applications, they all require a
central orchestrator that processes the deployment model and executes all
necessary tasks to deploy and orchestrate the application components on the
respective infrastructure. However, there are applications in which several
organizations, such as different departments or even different companies,
participate. Due to security concerns, organizations typically do not expose
their internal APIs to the outside or leave control over application
deployments to others. As a result, centralized deployment technologies are not
suitable to deploy cross-organizational applications. In this paper, we present
a concept for the decentralized cross-organizational application deployment
automation. We introduce a global declarative deployment model that describes a
composite cross-organizational application, which is split to local parts for
each participant. Based on the split declarative deployment models, workflows
are generated which form the deployment choreography and coordinate the local
deployment and cross-organizational data exchange. To validate the practical
feasibility, we prototypical implemented a standard-based end-to-end toolchain
for the proposed method using TOSCA and BPEL.},

abstract = {With the ongoing advances in the area of cloud computing, Internet of Things,
Industry 4.0, and the increasing prevalence of cyber-physical systems and
devices equipped with sensors, the amount of data generated every second is
rising steadily. Thereby, the gathering of data and the creation of added value
from this data is getting easier and easier. However, the increasing volume of
data stored in the cloud leads to new challenges. Analytics software and
scalable platforms are required to evaluate the data distributed all over the
internet. But with distributed applications and large data sets to be handled,
the network becomes a bottleneck. Therefore, in this work, we present an
approach to automatically improve the deployment of such applications regarding
the placement of data processing components dependent on the data flow of the
application. To show the practical feasibility of our approach, we implemented
a prototype based on the open-source ecosystem OpenTOSCA. Moreover, we
evaluated our prototype using various scenarios.},

abstract = {The growing usage of software and hardware in our everyday lives has lead to
paradigms such as Cloud Computing, Edge Computing, and the Internet of Things.
The combination of these paradigms results in distributed and heterogeneous
target environments: components of an application often need to be deployed in
different environments such as clouds, private data centers, and small devices.
This makes the deployment of distributed applications a complex and error-prone
challenge as deployment systems have to (i) support cloud deployments, (ii)
determine the location of physical resources, (iii) cope with security
mechanisms preventing inbound communication, and (iv) use hardware-constrained
devices. In this paper, we present an approach for the automated deployment of
distributed applications on heterogeneous target environments consisting of
public and private clouds, and devices. We especially tackle the issue of
deploying components in environments having restricted inbound communication
capabilities. We prototypically implemented and compared our approach based on
a smart home scenario using TOSCA and the OpenTOSCA Ecosystem.},

solutions from a range of different domains. However, these systems must
therefore be able to change components, configurations and environments, hence,
be adaptable at runtime. We present an approach that is based on the
combination of Situation-Aware Adaptation concepts and Deployment Models. The
general idea is to start processes that can change application structure and

developers who are interested in consuming computing resources as services
without the need to manage physical capacities or limits. There are several
deployment technologies and languages available suitable for deploying
applications to a single cloud provider. However, for multi-cloud application
deployments, multiple technologies have to be used and orchestrated. In
addition, the event-driven nature of serverless computing imposes further
requirements on modeling such application structures in order to automate their
deployment. In this paper, we tackle these issues by introducing an
event-driven deployment modeling approach using the standard Topology and
Orchestration Specification for Cloud Applications (TOSCA) that fully employs
the suggested standard lifecycle to provision and manage multi-cloud serverless
applications. To show the feasibility of our approach, we extended the existing

important issues in modern enterprise IT. Therefore, many deployment systems
have been developed that process deployment models for automating the
installation of systems. Creating such deployment models becomes more and more
complex as compliance plays an increasingly important role. Not only external
laws and regulations must be considered, but also a company’s internal
requirements must be fulfilled. However, this is a very complex challenge for
the modelers as they require a firm knowledge of all the compliance rules that
must be observed. As a result, this often leads to deployment models that
violate compliance rules due to manual modeling mistakes or because of
unawareness. In this paper, we introduce an approach that enables modeling of
reusable Deployment Compliance Rules that can be executed automatically to
check such regulations in declarative deployment models at design time. We

combines the features of an operating plat-form, a marketplace, a broker, and a

is a pluggable deployment framework that abstracts from proprietary services,

templates that contain (i) a deployment model for a certain kind of application

functionalities and management features. Thus, by selecting appropriate
templates, an application can be deployed on any infrastructure providing the

several case studies to evaluate its relevance.},

abstract = {The continuous growth of the Internet of Things together with the complexity of
modern information systems results in several challenges for modeling,
provisioning, executing, and maintaining systems that are capable of adapting
themselves to changing situations in dynamic environments. The properties of
the workflow technology, such as its recovery features, makes this technology
suitable to be leveraged in such environments. However, the realization of
situation-aware mechanisms that dynamically adapt process executions to
changing situations is not trivial and error prone, since workflow modelers
cannot reflect all possibly occurring situations in complex environments in
their workflow models. In this paper, we present a method and concepts to
enable modelers to create traditional, situation-independent workflow models
that are automatically transformed into situation-aware workflow models that
cope with dynamic contextual situations. Our work builds upon the usage of
workflow fragments, which are dynamically selected during runtime to cope with
prevailing situations retrieved from low-level context sensor data. We validate
the practical feasibility of our work by a prototypical implementation of a
Situation-aware Workflow Management System (SaWMS) that supports the presented
concepts.},

to speed up their business and to lower costs. Due to emerging technologies in
the field of Internet of Things, changing situations can be recognized
automatically, which provides the basis for an automated adaptation of process
executions in order to react to changing circumstances. Although approaches
exist that enable creating self-adapting workflows, a systematic modelling
approach that supports the specification of situational dependencies directly
in workflow models is missing. In this paper, we tackle this issue by
presenting a modelling extension called SitME that defines (i) an extensible
Situation Event type, (ii) the concept of Situational Scopes, and (iii) a
visual notation. As the introduced extension is language-independent, we apply
the approach to BPEL to validate its practical feasibility.},

in Cloud Computing. The Topology and Orchestration Specification for Cloud
Applications (TOSCA) supports automating provisioning by two different flavors:
(i) declarative processing is based on interpreting application topology models
by a runtime that infers provisioning logic whereas (ii) imperative processing
employs provisioning plans that explicitly describe the provisioning tasks to
be executed. Both flavors come with benefits and drawbacks. This paper presents
a means to combine both flavors to resolve drawbacks and to profit from
benefits of both worlds: we propose a standards-based approach to generate
provisioning plans based on TOSCA topology models. These provisioning plans are
workflows that can be executed fully automatically and may be customized by
application developers after generation. We prove the technical feasibility of
the approach by an end-to-end open source toolchain and evaluate its
extensibility, performance, and complexity.},

provisioning and decom-missioning of cloud applications. To reduce costs, these
applications can be terminated and restarted on demand. However, as an
application is terminated, its current application state, i.e., all application
specific data is deleted along with the running application instance. This
application state may be holding all business-critical information, and, hence,
must be saved before the application is terminated. One possibility to save
application states is to create VM snapshots although this is not always
possible or sufficient. Therefore, we introduce two approaches: (i) a concept
to generically terminate applications and save their internal state, and (ii)
an approach to reinstate the application in the same state again. To evaluate
their practical feasibility, we implemented a proof of concept in the OpenTOSCA
ecosystem.},

automated binding and monitoring of devices of smart environments are still
major issues. In this article we present a method and system architecture to
cope with these challenges by enabling (i) easy modeling of sensors, actuators,

(iii) the access to devices using different paradigms, and (iv) the monitoring

abstract = {The efficient provisioning of complex applications is one of the most
challenging issues in Cloud Computing. Therefore, various provisioning and
configuration management technologies have been developed that can be
categorized as follows: imperative approaches enable a precise specification of
the low-level tasks to be executed whereas declarative approaches focus on
describing the desired goals and constraints. Since complex applications employ
a plethora of heterogeneous components that must be wired and configured,
typically multiple of these technologies have to be integrated to automate the
entire provisioning process. In a former work, we presented a workflow
modelling concept that enables the seamless integration of imperative and
declarative technologies. This paper is an extension of that work to integrate
the modelling concept with the Cloud standard TOSCA. In particular, we show how
Hybrid Provisioning Plans can be created that retrieve all required information
about the desired provisioning directly from the corresponding TOSCA model. We
validate the practical feasibility of the concept by extending the OpenTOSCA
runtime environment and the workflow language BPEL.},
