The document discusses the PaaSport project which aims to create an open market of interoperable cloud platforms. Currently, giant vendors dominate the Platform as a Service (PaaS) market leading to customer lock-in. PaaSport seeks to enable choice between different cloud PaaS offerings and strengthen small-medium European cloud providers. The project will develop an open PaaSport cloud broker architecture, marketplace infrastructure, semantic models, and unified PaaS API to discover, select and manage applications across multiple interoperable cloud platforms.

- 2. PaaSport – 605193 2 Partners
- 3. PaaSport – 605193 3 Motivation • Giant vendors gained the lion’s share of the Platform as a Service (PaaS) market. – This dominance increases the lock-in of customers in a single Cloud platform. • Interoperability remains one of the greatest challenges that the longed-term adoption of Cloud computing is facing. • Companies developing applications should be able to choose between different Cloud PaaS offerings.
- 4. PaaSport – 605193 4 PaaSport Vision An open market of interoperable Cloud platforms will enable the IT industry to small-medium European Cloud providers and strengthen their market position
- 5. PaaSport – 605193 6 Expected Results • Open PaaSport Cloud-broker Architecture • Innovative PaaSport Marketplace Infrastructure • PaaSport Modelling Artefacts and Semantic Models • PaaSport Unified PaaS API

Editor's Notes
- FP7 project 3 years Dec 2013 – Dec 2016
- These are the partners We are the technical coordinators Research partners ucy, nuig, ihu etc Diyalogo: is a B2B platform that companies can promote themselves and their products. Move to PaaS because of increasing demands. However: Next slide
- preventing the portability of data or software
- Support decision making towards selection of the best-matching PaaS offering.
- 1) - 2) based on the technical, computing and business requirements of the European Software SMEs’ business applications. 3) infrastructure by developing proof‐of‐concept demonstrators which will be applied in different scenarios and setups across the enlarged Europe 4) Research results: (architecture, models, marketplace infrastructure and demonstrators) … in order to create a sustainable business ecosystem.
- Open PaaSport Cloud-broker Architecture Innovative PaaSport Marketplace Infrastructure PaaSport Modelling Artefacts and Semantic Models PaaSport Unified PaaS API PaaSport Marketplace Demonstrators PaaSport Lessons Learnt and Adoption Guidelines Wide‐scale dissemination and exploitation of the project results
- WP 3 refers to monitoring and accounting layer Consists of 5 components That have been/will be developed during the following tasks
- WP 3 refers to monitoring and accounting layer Consists of 5 components That have been/will be developed during the following tasks Use and extend WS-Agreement XML schema Negotiation protocol Service Consumer can create custom metrics SLA mechanism can also be used for monitoring custom-user performance requirements An SLA template for each PaaS offering is stored in the PaaSport persistence repository
- WP 3 refers to monitoring and accounting layer Consists of 5 components That have been/will be developed during the following tasks So far we been developing the Application Monitoring Component and the ALM component
- We defined the application lifecycle: an application goes through the following phases: Created Deployed Running
- an application goes through the following phases: Created Validated Deployed Running
- … Upcoming tasks: to develop the sla and offerings management components
- Load Balancer Central access endpoint for metric distribution Can be an HAProxy Load Balancer or a Message Queue Broker Metric Collection Layer Comprised of a number of stateless workers which will be utilized to process received monitoring metrics as to be stored in the database Web Service Layer and REST API API to be utilized either by other PaaSport components (e.g. SLA layer), users or developers to retrieve monitoring metrics Similarly, a number of web services can be used to enhance scalability Distributed Storage NoSQL database backend, e.g. Cassandra, for quick writes and easy to retrieve latest values. Also TTL can be added to metrics to automatically clean database REDIS can be also considered as an extra layer to store latest metrics values for quick retrieval for e.g. SLA Layer Controller The manager of the MaaS Layer. Will be used to scale (if needed) the monitoring infrastructure e.g. add/remove worker nodes, db nodes, etc. and configure monitoring process
- Task 3.2 m 13 -18 derived from the Service Level Agreement Policy Model (Task 3.1) and the vocabulary provided by the PaaSport SLA Model (Task 1.3) Allow Cloud vendors to manage the semantic profiles and the policies of their PaaS Offerings. Facilitate: the definition of the semantic profiles of the available PaaS Offerings based in the PaaSport PaaS Offering Model developed in Task 1.3, the definition of the SLA Policy of the available PaaS Offerings, based on the structure derived from the Service Level Agreement Policy Model (Task 3.1) and the vocabulary provided by the PaaSport SLA Model (Task 1.3), and the publication / advertisement of the semantic representations of the available PaaS offerings to the PaaSport Marketplace.
