 I work with a company called Concurve. Concurve is a travel and expense management solution company. It is a 22 years old company that has been recently acquired by SAP. So this expense report is about using closure and production at Concurve. So the problem that we set out to solve at Concurve using closure is to prepare the company for scale. Due to the acquisition, we are about to get about 10 times more traffic and load and to handle that kind of scale and to build the kind of system that we need. We need a very decoupled simple system that can be not built into layers that has a certain degree of resilient sophistication and a sense of harmony in the whole architecture. So the scope that we had when we started building the system was to actually rebuild some of the core components that span across multiple products. So the kinds of things that we are actually writing code to solve are things like authentication, authorization, profile data, identity management and such. And the approach that we took was to build microservices with a shared nothing architecture. So a deployment model sort of has, you know, I mean that allows for multiple versions at the same time. So we have an N plus one versions so that, you know, different lines, different products, they can talk to the different versions at the same time. And these are some of the open standards that we use in our platform. So all of you might be aware of West Bend JSON. JSON web programs are for communicating the claims and 509 certificates are used for authentication between hosts for the sensitive cells, O2 and similar for SSO and the later things. So when we started building the system, it is about, so the story is about one year old.
