GraphQL based solution architecture patterns

GraphQL is becoming popular in the tech industry as a replacement for REST. It really carries out significant advantages over existing mechanisms for the client-server type of communications.
In simple terms, GraphQL allows the client to choose which information it wants rather than receiving all the data which is available for the API. This is similar to a database query where we request only the required information. That is why it is called as GraphQL. We can do this easily with databases and data services runtime. But if you think about implementing the same capability for a REST API, you have to create so many different resources and the client has to call each and every one of these resources and handle the orchestration logic at the client-side. Otherwise, the API server has to do the heavy-lifting of orchestration. But this is not scalable with the changing demands from customers and the business.
The below medium post discusses possible solution architecture patterns that can be built with GraphQL.

How to setup an WSO2 API manager distributed setup with a clustered gateway with WSO2 ELB

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...

WSO2 ESB tuning performance with threads

I have written several blog posts explaining the internal behavior of the ESB and the threads created inside ESB. With this post, I am talking about the effect of threads in the WSO2 ESB and how to tune up threads for optimal performance. You can refer [1] and [2] to understand the threads created within the ESB. [1] http://soatutorials.blogspot.com/2015/05/understanding-threads-created-in-wso2.html [2] http://wso2.com/library/articles/2012/03/importance-performance-wso2-esb-handles-nonobvious/ Within this blog post, I am discussing about the "worker threads" which are used for processing the data within the WSO2 ESB. There are 2 types of worker threads created when you start sending the requests to the server 1) Server Worker/Client Worker Threads 2) Mediator Worker (Synapse-Worker) Threads Server Worker/Client Worker Threads These set of threads will be used to process all the requests/responses coming to the ESB server. ServerWorker Threads will be used to pr...

Performance Tuning WSO2 ESB with a practical example

WSO2 ESB is arguably the highest performing open source ESB available in the industry. With the default settings, it will provide a really good performance OOTB. You can find the official performance tuning guide in the below link. https://docs.wso2.com/display/ESB481/Performance+Tuning Above document includes lot of parameters and how to change them for best performance. Even though it provides some recommended values for the performance tuning, that is not straightforward. The values you put in the configuration files will highly reliant on your use case. Idea of this blog post is to provide a practical example of tuning these parameters with a sample use case. For the performance testing, I am using a simple proxy service which iterate through set of xml elements and send request to a sample server and aggregate the responses back to the client. <?xml version="1.0" encoding="UTF-8"?> <proxy xmlns="http://ws.apache.org/ns/synapse"     ...
