“…focusing on basic compute and data storage abstractions. Consequently, the area of cross-cloud management is now an important topic with researchers working on the concept of cross-cloud brokerage [34]. Note that the author has been heavily involved in such initiatives, organising a series of recent workshops on the topic of cross-cloud management (at IEEE Infocom'14 and Middleware '14) and carrying out research on the broker concept [35].…”

Distributed systems are at a watershed due to their increasing complexity. The heart of the problem is the extreme level of heterogeneity exhibited by contemporary distributed systems coupled with the need to be dynamic and responsive to change. In effect, we have moved from distributed systems to systems of systems. Following on from this, middleware is also at a watershed. The traditional view of middleware is no longer valid (i.e. as a layer of abstraction, masking the complexity of the underlying distributed system and providing a high-level programming model). In practice, middleware is often bypassed with complex systems constructed in a rather ad hoc manner as a mash-up of a variety of technologies. The end result is that middleware is no longer sure of its form or purpose and this lack of a viable approach is a huge barrier to the emergence of areas such as smart cities and emergency response systems. This paper argues that there is a need to fundamentally rethink the middleware landscape related to complex distributed systems. The core contribution of the paper is a set of fresh perspectives, which lead us in turn to novel principles and patterns for middleware and subsequently to new styles of platform. These perspectives include a move to emergent middleware, seeking flexible meta-structures for distributed systems, and a step away from generic to domain-specific technologies. A number of case studies are also presented to demonstrate what this might mean for future distributed systems.

Multi-cloud computing has been proposed as a way to reduce vendor dependence, comply with location regulations, and optimize reliability, performance and costs. Meanwhile, microservice architectures are becoming increasingly popular in cloud computing as they promote decomposing applications into small services that can be independently deployed and scaled, thus optimizing resources usage. However, setting up a multi-cloud environment to deploy a microservices-based application is still a very complex and time consuming task. Each microservice may require different functionality (e.g. software platforms, databases, monitoring and scalability tools) and have different location and redundancy requirements. Selection of cloud providers should take into account the individual requirements of each service, as well as the global requirements of reliability and scalability. Moreover, cloud providers can be very heterogeneous and offer disparate functionality, thus hindering comparison. In this paper we propose an automated approach for the selection and configuration of cloud providers for multi-cloud microservices-based applications. Our approach uses a domain specific language to describe the application's multi-cloud requirements and we provide a systematic method for obtaining proper configurations that comply with the application's requirements and the cloud providers' constraints.

“…These include jclouds 3 , Brooklyn 4 , Scalr 5 , SeaClouds [24], and others. They provide a 'least common denominator' between the different APIs which, as already mentioned, is sufficient for many cloud application developers whose intent does not exceed starting and stopping instances, However, any need outside the least common denominator API, e.g.…”

Abstract. Cloud computing has seen vast advancements and uptake in many parts of the world. However, many of the design patterns and deployment models are not very suitable for locations with challenged networks such as countries with no nearby datacenters. This talk describes the problem and discusses the options available for such locations, focusing specifically on community clouds as a short-term solution. The paper highlights the impact of recent trends in the development of cloud applications and how changing these could better help deployment in challenged networks. The paper also outlines the consequent challenges in bridging different cloud deployments, also known as cross-cloud computing.
