“…In older literature, the matter of multi-cluster collaboration was focused on bridging technological gaps between competing cloud infrastructure providers with possibly heterogeneous underlying technology stacks [21]. The vision of inter-cloud compatibility was embodied by shared or compatible APIs on the infrastructure level [7,8,19]. With more than a decade of hindsight, it is clear that these early attempts failed to convincingly demand industry adoption among the major cloud providers.…”

Multi-cluster federation is envisioned to be the next-generation cloud infrastructure, where it will play a vital part in the realization of concepts such as edge and fog computing. Orchestrating applications in federated environments poses new challenges to well-known research problems in various fields, such as load-balancing, auto-scaling, resource allocation and service migration. However, as access to real multi-cluster infrastructure is limited, a test-bed that provides similar characteristics to a real system is in demand. To enable researchers in associated fields to quickly setup experiments in a federated cloud environment, we have created the open-source sandbox FedApp that simplifies the process of deploying multiple virtual clusters in an Open-Stack environment with the possibility of adding realistic network characteristics between sites. Each cluster comes deployed with the open-source and production-grade container orchestrator Kubernetes, complete with federationwide monitoring using Prometheus/Grafana and simplified inter-cluster microservice communication using Istio.

“…Contrary to the relative multitude of server-side implementations, there has so far been only a single general-purpose OCCI client -the rOCCI-cli [13], part of the rOCCI Framework. That does not mean that there are no other OCCI clients in existence, but they are single-purpose implementations, typically providing only a subset of actions required by the workflow in their given user group.…”

The Open Cloud Computing Interface (OCCI) standard by OGF has become widely adopted in various cloud environments, such as the EGI Federated Cloud. It is currently supported by mainstream open source cloud management frameworks, e.g., OpenStack (through OCCI-OS) or OpenNebula (rOCCI) as well as others, less wide-spread ones. It is likewise supported by many workflow and submission tools used by user communities -VMDIRAC, JSAGA or SixSq. SlipStream to name but a few. OCCI is, however, found somewhat lacking in the availability of general-purpose clients supporting the standard. Only recently, its use was enabled only in the Ruby programming language through the rOCCI Framework, and command-line/scripting use was facilitated by the rOCCI-cli client. Naturally, there has been long-standing demand for OCCI support in other programming languages, primarily in Java. It has now been answered by the introduction of jOCCI -a native Java library implementing the OCCI class structure, rendering and transport specifications, currently in accordance with the OCCI v. 1.1 specification. Provided by the same product team already producing the rOCCI framework, it is more than "just another feature in the cloudscape." Rather than a simple translation of the client part of rOCCI, it is a brand new product -a choice that has been made not only to make it a truly native Java library, but also to introduce additional, independent, client to validate the generic functionality of existing OCCI server applications. This work describes the new library and compares it to rOCCI in terms of design and interoperability when used against other server-side OCCI implementations. It also discusses the relative merits of implementing the client library as a fresh product, relatively separate from rOCCI, rather than just providing Java bindings for the client side of the rOCCI Framework. Finally, the future of rOCCI and jOCCI is briefly discussed in view of the emerging OCCI v. 1.2 specification.
