AAI R2 Architecture Review
Delta from R1
R2 Usecase schema updates:
HPA Schema Updates - new object types/edges still being defined
https://lf-onap.atlassian.net/browse/AAI-742
PNF support - looks like we need to add an attribute in support of PNF use case
https://lf-onap.atlassian.net/browse/AAI-683
Scale in/out - existing schema is sufficient
Change management - existing schema is sufficient
R2 Usecase functionality updates:
Custom query for HPA usecase:
https://lf-onap.atlassian.net/browse/AAI-819
Other updates:
Clients will call AAI thru MSB, stretch goal is to retire HAPROXY and use MSB for load balancing/mS selection
https://lf-onap.atlassian.net/browse/AAI-671
Datastore will be JanusGraph on Cassandra:
https://lf-onap.atlassian.net/browse/AAI-24
Stretch goal: AAI will use AAF for Authentication/Authorization
A few microservices - mostly related to data integrity and data validation in the graph db, have been deferred to Casablanca. This does not change any agreed scope or APIs with other ONAP systems.
S3P Updates
Security
AAI core:
AAI UI:
AAI used 1-way TLS on APIs in Amsterdam and will continue in Beijing. There are still open questions about how the CA will be set up in Beijing, AAI uses a toy certificate signed by an openecomp CA which expires in December 2018
SONAR code coverage. Plan is to get to >50% on all repos.
Nexus IQ scans: We are in the process of migrating off AJSC to Spring Boot - Our first microservice has been converted (aai/resources) and has 0 security and 0 policy violations. The other microservices will be similarly converted. This should clear the overwhelming majority of the current exceptions on the other repos
Scalability and Resiliency
Working closely with OOM and MSB teams
https://lf-onap.atlassian.net/browse/OOM-591https://lf-onap.atlassian.net/browse/AAI-671Relying on kubernetes to manage AAI resilience, multiple instances of each stateless application server
AAI team has been working with on a clustered cassandra cluster. We have a working PoC and will be leveraging the clustered approach in Beijing. Single-site failover where we can lose a single node of the cassandra clustere which will be re-synced when kubernetes restores it.
https://lf-onap.atlassian.net/browse/AAI-539
Performance and stability
Focus to this point has been security and scalability/resiliency. We will participate in the integration team's performance testing
Seeking to meet 36hr stability soak test
Manageablility
Logging/EELF
AAI services can be instantiated in < 1hr
Usability
Working on splitting the API swagger so the readthedocs.io website can parse the RST
https://lf-onap.atlassian.net/browse/AAI-494
Information/Data Model Alignment
AAI's schema/edge rules will not change for the Beijing release to align with the modelling subcommittee's proposed information/data/runtime service and instance models. AAI is participating in the discussions and will map existing data objects to the approved clean versions when they are approved.
https://lf-onap.atlassian.net/browse/MODELING-61
API Updates
New endpoints for HPA use case
New custom-query to support HPA use case
New attribute on PNF object
Clients will use legacy APIs thru MSB
