Enterprise Integration for Beginners

What is Puppet? Puppet is IT automation software that helps system administrators manage infrastructure throughout its lifecycle, from provisioning and configuration to orchestration and reporting. Using Puppet, you can easily automate repetitive tasks, quickly deploy critical applications, and proactively manage change, scaling from 10s of servers to 1000s, on-premise or in the cloud. How the puppet works? It works like this..Puppet agent is a daemon that runs on all the client servers(the servers where you require some configuration, or the servers which are going to be managed using puppet.) All the clients which are to be managed will have puppet agent installed on them, and are called nodes in puppet. Puppet Master: This machine contains all the configuration for different hosts. Puppet master will run as a daemon on this master server. Puppet Agent: This is the daemon that will run on all the servers, which are to be managed using p...

Web Services Security , or to be more precise, SOAP message security, identifies and provides solutions for general computer security threats as well as threats unique to Web services. WSO2 Carbon supports WS Security, WS-Policy and WS-Security Policy specifications. These specifications define a behavioral model for Web services. A requirement for one Web service may not be valid for another. Thus, defining service-specific requirements might be necessary. The WSO2 SOA platform provides important security features to your service. By default the security features are  disabled . Securing a proxy service with basic authentication (Username Token) Pre-requisites  – Download the latest stable release of WSO2 ESB from here. Step 1 – Start WSO2 ESB server Step 2 – Create a Proxy Service. (We will use the Echo service shipped with WSO2 ESB here) <proxy xmlns=” http://ws.apache.org/ns/synapse&#8221 ; name=”PoxSecurityProxy” transports=”https” statistics=”dis...

Monitoring mediation statistics data with BAM Setting up Mediation Data Agent BAM Mediation Data Agent is used to collect statistics related to mediation data from WSO2 ESB and send to WSO2 BAM. The BAM server receives data events via its Thrift API. This is a binary protocol that enables fast data transmission between the ESB and BAM. It is possible to configure BAM Mediation Data Agent early so that you can predefine the statistics to be extracted from mediation data of ESB. In the configuration panel, specify the BAM server (Thrift server) related information and properties to be extracted from the Configuration Context of ESB. Also specify the Event Stream related parameters uniquely identified by a name and a version. Installing BAM Mediation Data Agent in the ESB The following installation instructions apply to WSO2 ESB version 4.5.x onwards. Download WSO2 ESB from http://wso2.com/products/enterprise-service-bus. When running both ESB and BAM s...

In this blog post I am going to describe about how to configure a WSO2 API Manager in a distributed setup with a clustered gateway with WSO2 ELB and the WSO2 G-REG for a distributed deployment in your production environment. Before continuing with this post, you need to download the above mentioned products from the WSO2 website. WSO2 APIM - http://wso2.com/products/api-manager/ WSO2 ELB - http://wso2.com/products/elastic-load-balancer/ Understanding the API Manager architecture API Manager uses the following four main components: Publisher Creates and publishes APIs Store Provides a user interface to search, select, and subscribe to APIs Key Manager Used for authentication, security, and key-related operations Gateway Responsible for securing, protecting, managing, and scaling API calls Here is the deployment diagram that we are going to configure. In this setup, you have 5 APIM nodes with 2 gateway...
