Nowadays, more and more Cloud providers are appearing on the market. In this context, a typical issue is represented by the management of distributed services deployed on different federated Cloud providers. Assuming that a distributed service consists of several microservices, in this paper, we specifically focus on the setup of virtual environments and on deployment tasks required in each Federated...
Cloud computing is becoming a relatively mature paradigm in the ICT landscape. In light of the growing appetite for resources and service levels on par with user expectations, multi-cloud scenarios are becoming the next frontier in the usage of distributed datacenters for private and hybrid Cloud scenarios. Application deployment in particular is a noteworthy feature to be evaluated as microservices...
DevOps entails a series of software engineering tactics aimed at shortening the actionable operation of software design changes. One of these tactics is to harness infrastructure-as-code, that is, writing a blueprint that contains deployment specifications ready for orchestration in the cloud. This abstract briefly discusses all necessary elements and abstractions in writing and maintaining that blueprint,...
The orchestration of application components across heterogeneous cloud providers is a problem that has been tackled using various approaches, some of which led to the creation of cloud orchestration and management standards, such as TOSCA and CAMP. Standardization is a definitive method of providing an end-to-end solution capable of defining, deploying, and managing applications and their components...
The OpenSON-MDCM provides an OpenStack API provisioning automation to allow multiple OpenStack instances, spanning in one site or multiple sites or in hybrid cloud, to be managed as a single OpenStack cloud.
Complex application deployment and management over multiple heterogeneous PaaS platform is one of the key problems that have emerged with the cloud technology revolution. Presently, vendor lock-in has become a major PaaS technology challenge. Multi-Cloud PaaS Architecture (MCPA) has been recently proposed research project, intended to resolve complexity and interoperability challenges. MCPA offers...
Provisioning cloud applications usually is a complex task as it involves the deployment and configuration of several components (e.g., load balancer, application server, database) and cloud services (computing, storage, CDN, etc.) also known as application blueprints or topologies. The Topology and Orchestration Specification for Cloud Applications (TOSCA) is a recent standard that has focused on...
The diversity in the way different cloud providers offer their services, give their SLAs, present their QoS, support different technologies, etc., complicates the portability and interoperability of cloud applications, and favors vendor lock-in. Standards like TOSCA, and tools supporting them, have come to help in the provider-independent description of cloud applications. After the variety of proposed...
Cloud orchestration helps arrange and coordinate the business processes or workflows to obtain the ultimate and efficient virtual computing resources management. The cloud orchestration standards are introduced to guide the development of the orchestration tools. TOSCA is an important new open cloud standard, introduced and approved by OASIS. Using TOSCA, the cloud providers are able to define the...
Cloud computing is driving formidable change in the technology industry and transforming how to do business in Europe and around the world. Despite the obvious advantages of cloud computing there are a number of issues that require solutions for Cloud computing to develop further. In particular challenges include (but are not limited to) lack of support for heterogeneous Cloud providers, lack of meaningful...
P-TOSCA portability is applied to transfer an application from one cloud provider to another. This paper presents an implementation of the P-TOSCA portability model, by specifying a corresponding topology and execution plan to a typical transaction-based eBay Finder SOA application, followed by a deployment procedure on a PaaS platform. The application topology uses specially defined types, templates...
As the sector of SaaS is being evolved, the need of portability and effective orchestration of Cloud-enabled applications over virtualised infrastructures is more apparent. In this paper we present a proof of concept (PoC) project together with industry partners which deals with the management of portable Cloud applications. Experimentation with a multi-tier Cloud application use case gives insights...
