“That’s why you’re seeing ethereum really outperform bitcoin,” said Mike Novogratz, CEO of Galaxy Investment Partners on CNBC’s “Squawk Box” on Wednesday. Instead of a gold-like store of value (a chief value proposition for bitcoin), ether and its rivals represent bets on sophisticated platforms for building smart contracts, non-fungible tokens (NFT), decentralized finance (DeFi) applications and other wizardry. One would expect that to mean good news not just for the price of ether, the native token of the Ethereum network, but also for its layer 1, or base layer, alternatives. Federal Reserve appears to be poised to take a more hawkish stance on monetary policy (for now, maybe), especially in light of recent high inflation data, cryptocurrency investors seem to be rethinking how they’re allocating their money in the sector. In the subsequent blog posts you will learn in detail about how an approuter and xsuaa server work in tandem in BTP CF environment.As the U.S. This article just provided an introduction to Approuter and XSUAA.
EAZYDRAW INDEPENDENT LAYER NOT AVAILABLE SERIES
This complete flow is complex with a series of redirects which can be pictorially represented as : This SAML assertions are then used by the authorisation server (XSUAA) to determine the authorisations (roles and scopes) of the user.

And once the authentication is successful, IDP responds back with a SAML assertion (also know as SAML Bearer assertion token) confirming the users identity. Thus when the application receives an initial unauthenticated request, approuter redirects the request to the IDP for authentication. It will be used together with IDP to authenticate and authorise the user and provide access to the backend APIs.Ī trust relationship is maintained between the identity provider (IDP) and the service provider (XSUAA). It acts as an “Authorisation Server” and authorisations of the applications are maintained with the help of technical roles (which then can be aggregate into business groups and role collection) assigned to the users. XSUAA : It is an implementation of CF UAA from SAP where XSUAA stands for “Extended Services for UAA”. Note: UAA is a Java webservice, hence it can be run in any java compliant webserver It is an open source identity management and authorisation service provided by cloud foundry.Its primary role is to serve as an oAuth2 provider, thus issuing access token to the client applications and validating these token for resource servers. UAA :It is also known as CF UAA where UAA for “User Authentication and Authorization”.

It also serves the static contents like webpages with the help of “routes” configuration The rules determining which http request should be forwarded to which destination are called “routes”. It forwards the request to the relevant micro-services with the help of destination configuration. If the JWT token is present, approuter will validate the token and forward the request to the target services directly, if the JWT token is absent the request will be forwarded to XSUAA servers to carry out the authentication and authorisation flow. It basically checks for JWT token which is generated only when the user has already been authenticated. Authentication and Authorisation Checks :.Since the services/apis are directly accessible, they can be triggered directly without going via approuter, hence it is recommended to validate the JWT tokens and scope at the service/api layer. Microservices is an architectural style wherein an application is structured as a collection of independent services. Let us address them one by one.Ĭloud Foundry is an open source platform (PAAS*) for developing ,deploying, running and scaling applications on the cloud. Hmm,too many technical terms used in the definition. Thus a central point of access is required which will not only authenticate but also forward(route) the incoming request to the respective microservices. Ī application running in cloud foundry environment can consist of several different microservices. This blogs provides a basic introduction Approuter, XSUAA and and how a request to application is getting served in CF environment.Ī application router also know as approuter is a nodejs application which serves as a single point of entry for all the other applications running in cloud foundry environment in SCP(now know as BTP i.e. Demystifying Approuter and XSUAA in Cloud Foundry
