WSO2 App Cloud Architecture



App Cloud SaaS application provides an user interface & REST API for app cloud users to deploy their application artifacts. The web UI is developed by Jaggery, and it invokes the REST API, which invokes following backend components to provide the app cloud solution.
Docker Client provides an interface to build images and push to the docker registry.
Kubernetes Client provides an interface to deploy applications in kubernetes cluster
DAO provides an interface to manipulate database operations to store meta data required for App Cloud in App Cloud DB
SOAP Client uses to invoke WSO2 Storage Server admin services to create databases and users
WSO2 Application Server provides an hosting environment to deploy App Cloud SaaS application
WSO2 Identity Server provides identity management configuring SSO with App Cloud SaaS application
WSO2 Storage Server provides RSS instances for app cloud developers to store application data.
WSO2 Data Analytics Server collects statistics published by deployed applications and provides dashboards to the app cloud users.
Docker Registry uses to store application images created using the deployable artifacts and runtimes.
Kubernetes provides runtime for deploy applications. Kubernetes namespaces provides tenant isolation and per pod per container per application will be deployed
End users will access the deployed applications via HAProxy. Further it provides Default URL and Custom URL features apart from load balancing.

WSO2 ESB communication with WSO2 ESB Analytics

This blog post is about how & what ports involved when connecting from WSO2 ESB to WSO2 ESB Analytics. How to configure: This document explains how to configure it https://docs.wso2.com/display/ESB500/Prerequisites+to+Publish+Statistics Let's say we have WSO2 ESB  and WSO2 ESB Analytics packs we want to run in same physical machine, then we have to offset one instance.  But we don't want to do that since WSO2 ESB Analytics by default come with the offset. So WSO2ESB will run on 9443 port, WSO2 ESB Analytics will run on 9444 port WSO2 ESB publish data to the WSO2 ESB Analytics via thrift. By default thrift port is 7611 and corresponding ssl thrift port is 7711 (7611+100), check the data-bridge-config.xml file which is in analytics server config directory .  Since we are shipping analytics products with offset 1 then thrift ports are 7612 and ssl port is 7712. Here, ssl port (7712) is used for initial authentication purposes of data publisher ...

Tips on using environment variables in WSO2 Integration Cloud

Environment variables allow you to change an application's internal configuration without changing its source code. Let’s say you want to deploy the same application in development, testing  and production environments. Then database related configs and some other internal configurations may change from one environment to another. If we can define these configurations as an environment variables we can easily set those without changing the source code of that application. When you deploy your application in WSO2 Integration Cloud, it lets you define environment variables via the UI. Whenever you change the values of environment variables, you just need to redeploy the application for the changes to take effect. Predefined environment variables Key Concepts - Environment Variables   provides you some predefined set of environment variables which will be useful when deploying applications in WSO2 Integration Cloud. Sample on how to use environment variables ...
