Personalized microservice
A global architecture (GLP), as disclosed herein, is based on the thin server architectural pattern; it delivers all its services in the form of web services and there are no user interface components executed on the GLP. Each web service exposed by the GLP is stateless, which allows the GLP to be highly scalable. The GLP is further decomposed into components. Each component is a microservice, making the overall architecture fully decoupled. Each microservice has fail-over nodes and can scale up on demand. This means the GLP has no single point of failure, making the platform both highly scalable and available. The GLP architecture provides the capability to build and deploy a microservice instance for each course-recipient-user combination. Because each student interacts with their own microservice, this makes the GLP scale up to the limit of cloud resources available—i.e. near infinity. |

Identification and adjustment of ineffective firewall rules
Network firewalls operate based on rules that define how a firewall should handle traffic passing through the firewall. At their most basic, firewall rules may indicate that certain network traffic should be denied from passing through a network firewall or indicate that certain network traffic should be allowed to pass through the network firewall. Manners of handling network traffic beyond simply allowing or denying the network traffic may also be defined by the rules. For instance, a rule may indicate that certain network traffic should be routed to a specific system. Thus, if an administrator of a network firewall determines that certain network traffic should be handled in a certain way by a network firewall, the administrator need only implement a firewall rule defining how that network traffic should be handled in the network firewall. |
