OSGi Community Event 2013 (http://www.osgi.org/CommunityEvent2013/Schedule) ABSTRACT The Cloud is booming. Economic advantages of utility computing, better time-to-market and apparent flexibility is what drives more and more businesses to move their critical systems into the third party infrastructures of cloud providers such as Amazon and Google. But are these providers and their infrastructures reliable? Are they secure and do they comply to local rules and regulations with regard to privacy sensitive data? Most "Service License Agreements" are nowhere near to accepted industry standards and, as such, certainly do not meet the requirements for time and mission critical systems. And what about that so called flexibility? Each provider introduces their own proprietary management interfaces and platform services locking customers in as fast as possible. The infrastructure may be virtualized, but unless great care is taken, moving between providers when infrastructure fails or a cheaper alternative emerges, becomes a major hurdle. This talk introduces INAETiCS, a research project that aims to define an open platform architecture and application model that supports truly dynamic and hybrid cloud applications by leveraging, but not locking into, existing public and private cloud solutions as well as native and embedded systems. Through a "Quality of Service" based deployment model, run-time automated infrastructure management, resource and topology management as well as dynamic software provisioning and configuration, the goal is to provide a non-intrusive environment where applications can run anywhere, anytime in a most optimal configuration. These concepts will be illustrated by looking at the implementations of key components and mechanisms, such as OSGi Remote Services, being developed by the open-source projects Amdatu Platform, Apache ACE and Apache JClouds where anyone interested is welcome to get involved.

Dynamic Hybrid Cloud Applications
INtelligent robust ArchitecturE for TIme
Critical Systems
An open collaboration effort that aims to define and demonstrate a
dynamic service oriented reference architecture that addresses the
requirements of time critical systems in a broad range of domains by
providing a single design and implementation space for all
subsystems, irrespective of control strategy
Open innovation
Define an open reference architecture based on a shared vision that can be applied freely in a broad range of domains.
● Implementations in Open Source● Spearheaded and funded by...
(Ultra) Large Online Systems that must reliably perform mission-critical functions, bridging operational and informational domains.
● Multiple Control strategies
● Functional Adaptive behaviour
● Technologically heterogeneous
● Geographically dispersed
Time Critical systems
(Ultra) Large Online Systems that must reliably perform mission-critical functions, bridging operational and informational domains.
● Multiple Control strategies
● Functional Adaptive behaviour
● Technologically heterogeneous
● Geographically dispersed
Time Critical systems
Define a unified design (and implementation) space across functional and technological domains that supports runtime evolution.
● Architectural consistency insystems design
● No architectural impedancebetween domains
● Runtime system evolutionof deployments
● Adaptive system behaviourto context changes
Consistent design space
Dynamic Services ArchitectureDynamic Services Architecture has the properties to address the requirements for Time Critical System domains.
● Consistent design space○ Published contracts○ Service lifecycle○ Multiple paradigms
● Runtime system evolution○ Semantic versioning○ Modular implementation○ Data stewardship○ (Native) OSGi

Application deployment is an autonomous and continuous process that optimizes the application’s performance given the capabilities of the available resources and budget.
● Managed Requirements○ (Non-) Functional / QoS ○ Budget
● Resource Capabilities○ (Non-) Functional / QoS○ Cost
● Runtime metrics○ Resource utilization○ QoS reporting

Application
The fabric layer is an extensible resource and network abstraction layer. It provides the basic infrastructure for the system state and interaction.
● Peer-to-peer network● Nodes/Zones● Zone coordination● Messaging/Relays
● Node capabilities○ Non-functional / QoS○ Functional endpoints○ Component containers
Fabric layer
The fabric is implemented by node agents that provide the core infrastructural services and base containers.
● Polyglot implementations● OSGi (Amdatu Platform)● Native OSGi (Apache Celix*)● Custom/Embedded

The container layer is an extensible application component layer. It provides life-cycle and context to application components.
● Component runtime● Provisioning● Application context● Supporting services● QoS monitoring
● Container capabilities● Non-functional / QoS○ Functional endpoints○ Multi-tenancy
Container layer
The container services are dynamic services provisioned onto node agents to support local application components with management, context and supporting services

Conceptual overview
INAETICS is ...
● A dynamic services architecture that provides a single consistent design space across domain and technology boundaries
● A fully dynamic deployment, resource and network management model allowing QoS driven runtime adaptive behaviour of systems
● A runtime platform being implemented in OSGi and Native OSGi/C by the Amdatu Platform and Apache Celix Open Source projects
● ... under construction ;)
