Based on a work at INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

2 The Digitized Earth Avalanche of data generated by various institutions all over Europe in numerous domains: Geography, Earth observation, Geology, Public Administration Private Geo Companies And also citizens INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

3 Why considering cloud technologies? We cannot act here Data Quantity and Quality Visibility, Accessibility and Sharing We can «push up» here for improving necessary services INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

4 Why considering cloud technologies? More and more needs for computations, simulations, peak responses to emergencies. Geospatial sciences & applications Enabling IT Resources We can act on here for accelerated procurement, for resources availability and pooling INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

5 Why considering cloud technologies? Some common characteristics about Geo Applications Usage Data intensity scenarios: storage but not only (e.g. performance of queries, synchronisation and integrity of data) Computing intensity scenarios: geo processing and computation on demand, procurement and release of resources Access intensity scenarios: World wide and/or concurrent access to information in case of particular events where maps / data/ services are required well beyond normal usage INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

6 Why considering the Cloud? Data must be provided / shared Efficiently Ubiquitously In various forms At no (or cheap) price Following standards and recommendations «packed» into relevant services INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

7 What is Cloud Computing? Cloud computing comes from the convergence of: service oriented architectures... loose coupling of services with operating systems and technologies... parallel computing large scale data analysis, up to thousands of machines virtualization independence from physical hardware Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (NIST) INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

8 Why considering the Cloud? Promises of the Cloud: Costs Reduction and simplification Reduced Total Cost of Ownership Technical staff, power supply, physical space hardware, cables, Scale economy among partners Share of Databases, servers, CPUs, Pay as you go: Operations Costs versus Infrastructure Costs Easy procurement (on demand, self service) INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

9 Why considering the Cloud? Promises of the Cloud: Not only about the Money! A cloud platform shall also provide Large computing power with ad hoc machines and network Various up to date Operating Systems and technologies Ubiquitous access and Quality of Service INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

13 About Cloud Computing Towards perfect capacity management? Starting costs remain reasonable Adaptive capacity: scaling down is as important as scaling up INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

14 Challenges of GeoData Services Infrastructures Diverse software requirements Diverse resource requirements Resource requirements vary over time Reduce costs INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

15 Challenges of GeoData Services infrastructures and Cloud Computing Diverse software requirements < > Virtualization To support a larger number of software requirements Diverse resource requirements < > Scalability To support large data volumes and high throughput To support increasing dataset sizes Resource requirements vary over time < > Elasticity To support a varying number of users To support on demand computations Reduce costs < > Pay as you go To reduce infrastructural cost during low platform usage INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

16 Why InGeoCloudS The project wants to demonstrate that a Cloud infrastructure can be used by public organisations to provide more efficient, scalable and flexible services for creating, sharing and disseminating spatial environmental data INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

18 Moving to the Cloud Think Layers!. Identify a common software stack Homogeneous infrastructure Scale economies Cloud compliance Define data volumes requirements Capacity planning Scalability challenges and requirements High throughput services Reliability Guarantee QoS for INSPIRE/OGC services Web Server Map Server Spatial Data Storage Operating System Geo Spatial Stack It is not simply about porting existing applications to the cloud, but rather to integrate them in a scalable geo spatial framework INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

19 InGeoCLOUDS Architecture: Auto Scaling Layers INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

20 InGeoCloudS Achievements The Architecture SCALABILITY + ELASTICITY + ON-DEMAND + MEASURED SERVICE INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

21 InGeoCloudS Scalable Services InGeoCloudS scalable services: Elastic File Server Elastic Database Server Elastic Web Server Elastic Map Server Elastic Linked Data Store All of the above are hot topics from a technological and scientific point of view. INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

22 Focus on INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

23 Elastic File Server We evaluated several technologies: S3FS, S3Backer, pnfs, LUSTRE, Our choice was GlusterFS No single point of failure No file metadata server Scalable Can add as many servers as needed at any time. Support standard protocols (e.g. NFS) Includes some optimizations, e.g., read ahead, write behind, async I/O, scheduling, caching It is currently sponsored by RedHat Other Cloud based storage solutions are based on the key value access pattern, which is incompatible with every other technology on the Geo Spatial Software stack This is almost a research challenge! INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,

24 GlusterFS at work Transparent access for applications Similar to NFS. Automatic set up on IGC instances. INSPIRE Compliant Data and Services on the Cloud WORKSHOP, Monday June 16 th,
