How can I execute a simulation of my scenario?
After the creation of all business entities of my scenario, I can execute the simulation via the API as described here.
How can I see the simulation results of my scenario?
After the execution of my scenario, I can retrieve my goals' achievability via the API as described here. On top of this, I can get details of the simulation results in form of income statements and balance sheets of a household.
How are backend systems and applications protected from API traffic spikes?
API traffic spikes are handled via load-balancing and high availability mechanisms. Envizage service in a highly available kubernetes cluster. Multiple instances (containers in kubernetes Pods) of each microservice run in the cluster for load balancing and high availability. Computational nodes that run our instances span across multiple availability zones.
How does throttling help me?
Throttling mechanisms can guarantee that excessive data rate from one data source that may be compromised will not affect the other tenants and the service itself.
What happens if a large number of end users try to invoke my API simultaneously?
Although excessive workload from many users is handled via load-balancing and high availability mechanisms, the API also throttles requests for each clients individually. Each account tier has its own throttling limits set which can't be exceeded.
Management and Operations
How can I monitor my APIs?
Monitoring information is accessible via the Developer Console under the Plan tab.
Are my data backed-up? What is the backup policy?
A continuous backup mechanism takes incremental backups of data in the Envizage cluster, ensuring your data backups are typically just a few seconds behind the operational system. Restore from stored snapshots or from a selected point in time within the last 24 hours is possible at any time.
How do I authorise access to Envizage APIs?
For each new tenant of the system, we issue a pair of ClientId and ClientSecret and then we follow the Client Credentials Grant flow as specified in the OAuth 2.0 specification to create admin account for the new client and then register users under that ClientId. Those admin accounts are able to login and access information about the registered users like user names, emails (if provided) and anonymised access analytics logs.
Is Envizage API usage logged?
All activity by accounts with elevated privileges (admins, client admins and client accounts) are automatically recorded in an audit trails database collection. Extensive (pseudonymised) analytics and metrics are captured as number of logins, registrations, failed login attempts etc in various timeframes. Audit trails and monitoring information is accessible via the Envizage Backoffice and by its management API.
Is my data protected from unauthorized access?
All tenants (clients) of Envizage use the same database instance. There is no hard segregation in the environment between clients, only a rigorously tested logical layer. Envizage ensures the segregation by a set of filters that act as a switch to authorize access to resources based on a client.
There is also a dedicated instance option set up for individual clients which is physically separated from the main multi-tenant instance. Please contact sales for details about this.
Is my data encrypted at rest and in transit?
- API service catalog is served over SSL/TLS connections using a SHA-2 certificate.
- Stateless session management is done with JWT (JSON web tokens) signed with RSA 2048 bits key.
- MongoDB database is encrypted using Transparent Data Encryption (TDE).
- Encrypted AWS EBS volumes are used for our compute nodes.
EU GDPR Regulation
Is Envizage Developer API GDPR compliant?
Envizage runs on the Amazon Web Services global infrastructure platform. All Amazon services are GDPR ready.
What is the purpose of data processing by Envizage Developer API?
Envizage Developer API is a managed service that makes it easy for developers to simulate financial scenarios for household accounts. It does not perform further processing of the household data.
How does Envizage Developer API performs consent management?
Envizage Developer API is ready to integrate with the consent policy of any tenant. Each client can define their own T&Cs and make them available from the Admin Console.
