How the Cloud works… Virtualization of resources: Compute, Network and Storage

How the Cloud works… Cloud provisioning models

Cloud Services

Cloud Main Advantages 1. Scalability 2. Elasticity 3. High Availability

Scalability Add nodes on the fly! - Create new VMs through software rather than setup new machines. - Upgrades VMs with the click of a button - Add nodes to extend the cloud infrastructure without downtime

Elasticity Allows automated scaling in order to adapt to the current demands Exampe: Video streaming company

High Availability Minimized downtime for services Increased IT-efficiency results to a better infrastructure management reducing downtime significantly

Allows the virtualization of resources Offers services to manage the virtualized resources

OpenStack architecture Distributed, modular and scalable.

Virtualization

Horizon: Provides a GUI for basic cloud administration functionality KeyStone: Authorization. Manages users, tenants, roles etc. Ceilometer: Monitors, collects and stores usage data

Heat: Orchestration. Automates deployment for compute, storage and network resources. Cinder: Block storage for VMs Neutron: Networking

Swift: Object storage service for storing and retrieving data. Glance: Disk image service Nova: Compute Service. Schedules and manages VM instances

Cloud Application Use Generic Enablers as building blocks for apps!

Cloud Application Business Logic Authentication Database connect GE2

Generic Enablers A GE consists of a set of services with common background all designed using the REST architectural style. Example GE Services: Get users Get user Delete user Create new user

GE Generic Enablers REST API services GET – POST -DELETE Output: Call service using the URL: GET www.myservice.com/users GE POST www.myservice.com/users DELETE www.myservice.com/users?id=1 Output: JSON or XML & response code GET – POST -DELETE

SE Specific Enablers GE2 GE1 REST API Output: JSON or XML Combination of services from at least 2 different GEs GE2 GE1 SE REST API Output: JSON or XML

Example Architecture: Interact

Apps/Services Provider The VISION FI-WARE will be a technological foundation to satisfy the demands of application/services providers and consumers across various usage areas, stimulating and cultivating a sustainable FI service ecosystem Consumers People Businesses Apps/Services Provider Platform Provider

Elements & Functions of FI Core Platform The FI Core Platform comprises a set of technological “Generic Enablers” which are considered general purpose and common to several current and future “usage areas” Generic Enablers (therefore, the FI Core Platform) will provide open interfaces for development of Applications Usage area projects under the PPP Cloud Hosting App/Service Delivery Support Services Interface to IoT Interface to Network Security, Trust Dev Tools

FI-WARE Generic Enablers (GEs) User authentication Why not having a unique authentication system for all our actions? Identity management GE Offers authentication and authorization for users, services or applications

FI-WARE Generic Enablers (GEs) JSON Data Storage A service that provides an API for storing and retrieving json objects. We don’t need to worry about scaling! The service takes care of that!

FI-WARE Generic Enablers (GEs) Context Broker Users subscribe to context and get notified on context updates. Allows efficient filtering E.g., Interest topic distribution application

Cloud in sensitive domains: Healthcare provisioning Why cloud computing & what is the problem? Standards, regulations, recommendation legislation, ISO standards Security standards (ISO 27000) there are severe restrictions to data transfer, storage, aggregation and analysis Cloud computing: remote services (data management in distant datacenters)

Problem area: Healthcare provisioning Data Data Data Data Data Data Data Data Data Data Data Data Data BigData Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data

Hybrid Cloud Deployment: Software to Data A reverse cloud approach that offer the required framework (Public Cloud) to allow Software Enablers to be initiated at clients’ sites and to be hosted in a Private Cloud Software to data cloud model Provider Edge Consumer Edge Healthcare private cloud Platform for developers Provider of services Deployment of Software Blocks as utility services Provision of Software Blocks

FI-STAR at a glance Future Internet Social and Technological Alignment Research (FISTAR) project attempting to identify suitable software to data solutions based on Generic Enabler technology provided from FI-WARE to establish early trials in the health domain FI-STAR will develop and deploy 8 use case Future Internet (FI) applications FI-STAR Use Case Private Cloud FI-STAR developers Provider: FI-WARE Deployment of Software Blocks as utility services Provision of Software Blocks 45

Overall Goal FI-STAR establishes early trials in the Health Care domain building on Future Internet (FI) technology leveraging on the outcomes of FI-PPP Phase 1.  To meet the requirements of a global Health industry FI-STAR will use a fundamentally different, “reverse” cloud approach that is.  It will bring the software to the data, rather than bringing the data to the software. FI-STAR will deploy and execute 7 early trials across Europe FI-STAR will validate the FI-PPP core platform concept by using GEs to build its framework (7 use cases applications)

Building blocks of FI-Applications Generic Enablers (GEs) are considered as software modules: offer various functionalities along with protocols interfaces for operation and communication. Using GEs FI-STAR will develop Specific Enablers (SEs) that highlight: Light-weight applications Robust security and privacy functionality Optimal usage of network resources Virtualization of resources
