The final layer is the data tier and, as mentioned above, it is responsible for data storage, not only of the influenza rates but also of the user's personal information, availability and state of slaves, IP addresses, assigned tasks, etc.
"Applications, the web tier, the data tier, all your infrastructure layers are now things you can subscribe to," he said.
YugaByte insists that while the container ecosystem led by Docker & Kubernetes has enabled enterprises to realize this vision for the application tier, the data tier has remained a big challenge.
The data tier handles data requests by the application tier or domain tier and communicates with the SEAMLESS database to retrieve this data.
The data tier consists of domain database that houses the clinical annotations data, the security data (users, groups, roles, protected elements, etc).
The data tier includes PostgreSQL relational database (http://www.postgresql.org/) with PostGIS (http://postgis.refractions.net/) extension to effectively handle integer range queries.
In two case studies the approach results in up to 54% reduction in monetary costs compared to a premise only deployment and 56% improvement in response time compared to a naive partitioning where the application-tier is deployed in the public cloud and the data-tier is on private infrastructure.
We can have 9 possible deployment variations with each of the data-tier and the application tier being (i) on the private premise, (ii) on the public cloud, or (iii) partitioned for hybrid deployment.
That work does not handle partitioning of the data-tier.
At the data-tier it consists of tables storing data for account, accountprofile, holding, quote, etc.
Thus the model for the data-tier should be compatible for integration with an approach to application partitioning such as the one described in Section 3.
