abstract = {In many domains, patterns are a well-established concept to capture proven
solutions for frequently reoccurring problems. Patterns aim at capturing
knowledge gathered from experience at an abstract level so that proven concepts
can be applied to a variety of concrete, individual occurrences of the general
problem. While this principle makes a pattern very reusable, it opens up a gap
between the (i) captured abstract knowledge and the (ii) concrete actions
required to solve a problem at hand. This often results in huge efforts that
have to be spent when applying a pattern as its abstract solution has to be
refined for the actual, concrete use cases each time it is applied. In this
work, we present an approach to bridge this gap in order to support, guide, and
ease the application of patterns. We introduce a concept that supports
capturing and organizing patterns at different levels of abstraction in order
to guide their refinement towards concretized solutions. To show the
feasibility of the presented approach, we show how patterns detailing knowledge
at different levels of abstraction in the domain of information technology are
interrelated in order to ease the labor-intensive application of abstract
patterns to concrete use cases. Finally, we sketch a vision of a pattern
language for films, which is based on the presented concept.},

abstract = {Due to the current hype around cloud computing, the term {\^a}€śnative cloud
application{\^a}€ť becomes increasingly popular. It suggests an application to
fully benefit from all the advantages of cloud computing. Many users tend to
consider their applications as cloud native if the application is just bundled
in a virtual machine image or a container. Even though virtualization is
fundamental for implementing the cloud computing paradigm, a virtualized
application does not automatically cover all properties of a native cloud
application. In this work, we propose a definition of a native cloud
application by specifying the set of characteristic architectural properties,
which a native cloud application has to provide. We demonstrate the importance
of these properties by introducing a typical scenario from current practice
that moves an application to the cloud. The identified properties and the
scenario especially show why virtualization alone is insufficient to build
native cloud applications. Finally, we outline how native cloud applications
respect the core principles of service-oriented architectures, which are
currently hyped a lot in the form of microservice architectures.},

science. They document proven solutions to recurring problems in a specific

specific use cases. However, since the concept of patterns aims at
generalization and abstraction of solution knowledge, it is difficult to apply
solutions provided by patterns to specific use cases, as the required knowledge
about refinement and the manual effort that has to be spent is immense.
Therefore, we introduce the concept of Solution Implementations, which are
directly associated to patterns to efficiently support elaboration of concrete
pattern implementations. We show how Solution Implementations can be aggregated
to solve problems that require the application of multiple patterns at once. We
validate the presented approach in the domain of cloud application architecture
and cloud application management and show the feasibility of our approach with

abstract = {When managing IT environments and designing business processes, compliance
regulations add challenges. Especially considering adaptive environments in the
context of a service-oriented architecture in combination with exploiting the

Measures have to be taken on many application levels - including business
processes, IT architecture, and business management. Although a lot of work has
been done on various approaches covering compliance on one or more of these
levels, in large companies more than one approach is likely to be employed.
However, a unified approach for supporting the compliance tasks - like
introduction, maintenance, and especially adaptation - on different levels of
business and IT is missing. This work introduces this unifying approach, which
links compliance requirements to implementing technology using variable
compliance descriptors in order to comprehensively support compliance tasks.
The advantage of this approach is that the impact of compliance on these
different levels is tracked, thus enabling change propagation from changes in
compliance requirements to infrastructure and business process reconfiguration.},

abstract = {In many ways cloud computing is an extension of the service-oriented computing
(SOC) approach to create resilient and elastic hosting environments and
applications. Service-oriented Architectures (SOA), thus, share many
architectural properties with cloud environments and cloud applications, such
as the distribution of application functionality among multiple application
components (services) and their loosely coupled integration to form a
distributed application. Existing service-based applications are, therefore,
ideal candidates to be moved to cloud environments in order to benefit from the
cloud properties, such as elasticity or pay-per-use pricing models. In order
for such an application migration and the overall restructuring of an IT
application landscape to be successful, decisions have to be made regarding (i)
the portion of the application stack to be migrated and (ii) the process to
follow during the migration in order to guarantee an acceptable service level
to application users. In this paper, we present best practices how we addressed
these challenges in form of service migration patterns as well as a methodology
how these patterns should be applied during the migration of a service-based
application or multiples thereof. Also, we present an implementation of the
approach, which has been used to migrate a web-application stack from Amazon
Web Services to the T-Systems cloud offering Dynamic Services for

business-centric manner, without any knowledge of the actual implementation

means to represent business goals and requirements. A business transaction is
typically implemented by a choreography of different parties contributing to
the accomplishment of the common agreement. To meet the constantly changing
requirements for all parties in a business transaction choreographies often
have to be adapted (e.g. change in the distribution on different execution
environments). The resulting challenge is that the execution state of a
choreography executed on several locations has to be propagated to the business
analyst to enable monitoring of (adapted) business transactions. For this
purpose we introduce a meta-model and state model of business transactions.
Based on these models, we introduce a two-stage monitoring approach involving
state propagation of the execution status of the adapted choreography to the
original choreography and from there to the business transaction.},

topology describing their entire IT infrastructure, software, on-premise and
off-premise services, processes, and their interrelations. Especially due to
acquisitions, mergers, reorganizations, and outsourcing there is no clear ‘big
picture’ of the enterprise topology. Through this lack, management of
applications becomes harder and duplication of components and information
systems increases. Furthermore, the lack of insight makes changes in the
enterprise topology like consolidation, migration, or outsourcing more complex
and error prone which leads to high operational cost. In this paper we propose
Enterprise Topology Graphs (ETG) as formal model to describe an enterprise
topology. Based on established graph theory ETG bring formalization and
provability to the cloud. They enable the application of proven graph
algorithms to solve enterprise topology research problems in general and cloud
research problems in particular. For example, we present a search algorithm
which locates segments in large and possibly distributed enterprise topologies
using structural queries. To illustrate the power of the ETG approach we show
how it can be applied for IT consolidation to reduce operational costs,
increase flexibility by simplifying changes in the enterprise topology, and
improve the environmental impact of the enterprise IT.},

architects and developers have to respect the characteristics of the cloud

cloud offering descriptions and cloud application architectures, developers are
guided during the identification of patterns applicable to their problems. We
cover the proceeding how we identified patterns, give an overview of previously
discovered patterns, and introduce one new pattern. Further, we propose a

application to be deployed in different runtime environments. Existing and new
technologies and tools are leveraged to realize these classes of variability.

way. This is especially true for ITdriven business processes as enterprises may
face considerable fines when violating laws and regulation in their business
processes. Through the advent of cloud computing, a new dimension of compliance
requirements within the research area of compliant business process design has
emerged. Datasovereignty is one of the major compliance concerns enterprises
have to deal with when moving applications and data to the cloud. Enterprises
are fully responsible for their data, also when the data is not present within
their IT premises anymore. This lead to the policy that specific data must not
leave the IT premises of the enterprise. In this paper we present an approach
to support the human process designer in modelling compliant business
processes. We are focusing on compliance requirements which have to be
considered in the field of cloud computing. These requirements have been
created to meet laws and regulations. These laws and regulations are
considering data which is sent around between countries, for example.
Considering the characteristics of these requirements, we deal with
data-centric compliance rules here.},

the middleware and hardware to run the services. Thus, service composition
techniques are typically limited to choosing between a set of available
services. In this paper we keep the black-box nature and the principle of
information hiding for the service implementation, but break up services
vertically. By introducing vertical service composition, we allow services to
be provisioned on the right middleware when they are requested, thus making
service-binding more powerful as services with the desired quality of service
can be provisioned on demand. We introduce the concept of vertical service
composition and present an extension to an enterprise service bus that
implements the concept of vertical service composition by combining concepts
from provisioning with those of (dynamic) service binding.},

abstract = {Abstract—To be successful a cloud service provider has to target a preferably
large customer group to leverage economies of scale. Therefore an application
offered as a service in the cloud is often configurable regarding
non-functional qualities, such as location or availability. Since many of these
qualities depend on the resources on which the service is hosted, a large
number of computing environments has to be managed by the service provider.
This paper analyses the challenges arising from such a scenario and identifies
several optimization opportunities originating from an intelligent distribution
of users among the functionally equal resources with different quality of
services. A framework enabling the development of distribution strategies
exploiting these opportunities is defined. It allows modeling of resources,
their deployment dependencies, and users with specific demands. An architecture
and prototype of a management system is introduced to handle the required
resource provisioning and user request routing. Several optimization strategies
are defined and their performance is evaluated using statistical data of an
existing cloud service provider.},

They document proven solutions to recurring problems in a specific context and

generalization and abstraction of solution knowledge, it is difficult to apply
patterns to specific use cases, as the required knowledge about refinement and
the manual effort that has to be spent is often immense. Therefore, we
introduce the concept of Solution Implementations, which are concrete solution
artifacts directly associated with patterns in order to efficiently support
elaboration of concrete pattern implementations. In addition, we show how
Solution Implementations can be aggregated to solve problems that require the
application of multiple patterns at once. We evaluate the presented approach by
conducting use cases in the following domains: (i) Cloud Application
Architecture, (ii) Cloud Application Management, (iii) Costumes in Films, (iv)

abstract = {Cloud-based applications require a high degree of automation regarding their IT
resource management, for example, to handle scalability or resource failures.
This automation is enabled by cloud providers offering management interfaces to
be accessed by applications without human interaction. The properties of
clouds, especially pay-per-use billing and low availability of individual
resources, demand such a timely system management. We call the automated steps
to perform one of these management tasks a “management flow”. Because the
emerging behavior of the overall system comprised of many such management flows
is often hard to predict, we propose to define abstract management flows
describing common steps handling the management tasks. These abstract
management flows may then be refined for each individual use case. We cover
abstract management flows describing how to make an application elastic,
resilient regarding IT resource failure, and how to move application components
between different runtime environments. The requirements that these management
flows have on handled applications are expressed using architectural patterns
that have to be implemented by the applications. These dependencies result in
abstract management flows being interrelated with architectural patterns in a
uniform pattern catalog. We propose a method using such a catalog to guide
application managers during the refinement of abstract management flows at the
design time of an application. Following this method, runtime-specific
management functionality and management interfaces are used to obtain automated
management flows for a developed application.},

business process management and optimization has been applied to different

Based on the ecological characteristics of a business process, proper
environmentally sustainable adaptation strategies can be chosen to improve the
total environmental impact of the business process. We use ecological
sustainable adaptation strategies that are described as Green Business Process
Patterns. The application of such a Green Business Process Pattern, however,
affects the business process layer, the application component and the
infrastructure layer. This implies that changes in the application
infrastructure also need to be considered. Hence, we use best practices of
cloud application architectures which are described as Cloud Patterns. To guide
developers through the adaptation process we propose a pattern-based approach
in this work. We correlate Cloud Patterns relevant for sustainable business
processes to Green Business Process Patterns and organize them within a
classification. To provide concrete implementation support we further annotate
these Cloud Patterns to application component models that are described with
the Topology and Orchestration Specification for Cloud Applications (TOSCA).
Using these annotations, we describe a method that provides the means to
optimize business processes based on Green Business Process Patterns through
adapting the implementation of application components with concrete TOSCA
implementation models.},
