Geo‐based services

Flemish SDI online


� Capacity (No limits)� Availability (24/7)� No authentication� Unexpected temporal over‐usage� Compliancy – vendor independent interface (INSPIRE/OGC/standard endpoints)� Manageable architecture & avoid infrastructure management� Cost effective

Non functional requirements


� Make all components scalable at any moment� Locate all components in one environment� Use the best available up to date technology� Focus to the implementation

Best practices


� The public cloud scales� Shop technology & infrastructure� Tend to PAAS/SAAS� We have chosen Microsoft Azure.

Solving the problem


� Portal runs as tomcat appservice using Conterra MapApp & Azure SQL DB� Monitored by Application Insights� Logging by GA

Performance & instant up‐to‐date tiles in one INSPIRE View Service (Tools and technologies ‐ Visualisationand mapping ‐ 19/09/2018 ‐ 16:00 ‐ Room: Gorilla 3)

� Migrating GEONETWORK to Azure as tomcat app service (PAAS)� Using Azure SQL DB� Fully scalable

Metadata & CSW (under construction)


� Services available as Azure App services or Azure Cloud services� Full scalable� Logged & monitored with Application insights� Reported with MS PowerBI

Misc services


� How to move the source data to Azure? (Azurewebjobs, powershell & AZCopy)

� How to control costs? (Power BI)� Monitor and log efficient (application Insights,

azure streaming analytics) – tune the tresholds� Implement autoscale

Challenges


� Moving from on premise to the cloud is an architectural challenge that takes time

� Moving from IAAS (on premise & cloud) to PAAS/SAAS is a mindset� Keeping data synced between the cloud and internal processes is a challenge� Moving to the cloud offers enhanced availability.� Enhancing performance is continuous a work item� Moving to the cloud resulted in higher agility – faster architectural changes� More monitoring. Good monitoring is a continuous effort.� Governance of the system is not by default – continuous work area� The Flemish SDI is now more reliable. Availability = + 99%
