abstract = {Complex applications are typically composed of multiple components. In order to
install these components all their dependencies need to be satisfied. Typically
these dependencies are resolved, downloaded, and installed during the
deployment time and in the target environment, e.g., using package manager of
the operating system. However, under some circumstances this approach is not
applicable, e.g., if the access to the Internet is limited or non-existing at
all. For instance, Industry 4.0 environments often have no Internet access for
security reasons. Thus, in these cases, deployment packages without external
dependencies are required that already contain everything required to deploy
the software. In this paper, we present an approach enabling the transformation
of non-self-contained deployment packages into self-contained deployment
packages. Furthermore, we present a method for developing self-contained
deployment packages systematically. The practical feasibility is validated by a
prototypical implementation following our proposed system architecture.
Moreover, our prototype is evaluated by provisioning a LAMP stack using the
open-source ecosystem OpenTOSCA.},

abstract = {To automate the deployment of applications several deployment technologies have
been developed. However, the management of deployed applications is only
partially covered by existing approaches: While management functionalities such
as scaling components or changing their configurations are covered directly by
cloud providers or configuration management technologies such as Chef, holistic
management processes that affect multiple components probably deployed in
different environments cannot be automated using these approaches. For example,
testing all deployed components and their communication or backing up the
entire application state that is scattered across different components requires
custom management logic that needs to be implemented manually, $\backslash$eg using
scripts. However, a manual implementation of such management processes is
error-prone, time-consuming, and requires immense technical expertise.
Therefore, we propose an approach that enables automatically generating
executable management workflows based on the declarative deployment model of an
application. This significantly reduces the effort for automating holistic
management processes as no manual implementation is required. We validate the
practical feasibility of the approach by a prototypical implementation based on
the TOSCA standard and the OpenTOSCA ecosystem.},

abstract = {New paradigms such as edge computing opened up new opportunities for
distributing applications to meet use-case-specific requirements. For
automating the deployment of applications, deployment models can be created
that describe the application structure with its components and their
relations. However, the distribution is often not known in advance and, thus,
deployment models have to be restructured. This can result in problems that
have not existed before, e.g., components previously deployed in the same
network were distributed, but security mechanisms are missing. Architecture
patterns can be used to detect such problems, however, patterns describe only
generic technology-independent solutions, which cannot automatically be applied
to applications. Several concrete technologies exist that implements the
pattern. Which solutions are applicable to a particular application is
determined by, e.g., its hosting environment or used communication protocol.
However, the manual effort to determine and implement appropriate solutions is
immense. In this work, we present an approach to automate (i) the determination
of solutions for an application using first-order logic and (ii) the adaptation
of its deployment model accordingly. To validate the practical feasibility, we
present a prototype using the cloud standard TOSCA and the logic programming

abstract = {The automated deployment of cloud applications is of vital importance.
Therefore, several deployment automation technologies have been developed that
enable automatically deploying applications by processing so-called deployment
models, which describe the components and relationships an application consists
of. However, the creation of such deployment models requires considerable
expertise about the technologies and cloud providers used—especially for the
technical realization of conceptual architectural decisions. Moreover,
deployment models have to be adapted manually if architectural decisions change
or technologies need to be replaced, which is time-consuming, error-prone, and
requires even more expertise. In this paper, we tackle this issue. We introduce
a meta-model for Pattern-based Deployment Models, which enables using cloud
patterns as generic, vendor-, and technology-agnostic modeling elements
directly in deployment models. Thus, instead of specifying concrete
technologies, providers, and their configurations, our approach enables
modeling only the abstract concepts represented by patterns that must be
adhered to during the deployment. Moreover, we present how these models can be
automatically refined to executable deployment models. To validate the
practical feasibility of our approach, we present a prototype based on the
TOSCA standard and a case study.},

abstract = {The automation of application deployment is vital today as manually deploying
applications is too slow and error prone. For this reason, various deployment
automation technologies have been developed that process deployment models to
automatically deploy applications. However, in many scenarios, these deployment
models have to be created in collaborative processes involving multiple
participants that belong to independent organizations. For example, in data
analytics scenarios, often external data scientists develop algorithms to
process business-critical data of a company, while IT experts specify the
technical infrastructure to deploy algorithms and data. However, as these
deployment modeling processes are typically highly iterative and as the
participating organizations may have competing interests, the degree of trust
they have in each other is limited. Thus, without a guarantee of
accountability, iterative collaborative deployment modeling is not possible in
business critical domains. In this paper, we propose a decentralized approach
that aims at achieving accountability in collaborative deployment modeling
processes by utilizing public blockchains to store intermediate states of the
collaborative deployment model in a way that guarantees its integrity and
allows obtaining the history of changes it went through. The approach utilizes
the same blockchain to establish the identity and authenticity of all
participants of the process. We validate our approach by providing an
architecture and a prototypical implementation of a blockchain-based deployment
modeling environment based on the TOSCA standard.},

abstract = {In the arts and humanities, research applications play a central role in
securing and presenting digital results. However, due to their steadily
increasing number and their heterogeneity, it is difficult to ensure the
sustainability and durability of this kind of living systems from an
organizational point of view. This paper describes a project for the
preservation of specialized web-based research applications in the humanities.
The SustainLife project investigates to what extent methods and technologies of
professional cloud deployment and provisioning strategies can be applied to
problems of long-term availability of research software as they are omnipresent
in humanities data centers such as the Data Center for the Humanities (DCH) at
the University of Cologne. Technological basis of the project is the OASIS
standard TOSCA and the Open Source implementation OpenTOSCA, respectively,
which was developed at the Institute for Architecture of Application Systems
(IAAS) at the University of Stuttgart. In the course of the project selected
use cases from the field of Digital Humanities (DH) will be modeled in TOSCA to
be able to automatically deploy them upon request at any time. The TOSCA
standard enables a portable description of the modeled systems independent of
specific providers to facilitate their long-term availability. The aim is to
provide system components described in the use cases in a component library, as
well as in the form of TOSCAcompliant application templates to make them
available for reuse in other DH projects.},

abstract = {In recent years, several technologies were developed enabling the automated
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.},
