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.

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

How puppet works in your IT infrstructure

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

How to configure timeouts in WSO2 ESB to get rid of client timeout errors

WSO2 ESB has defined some configuration parameters which controls the timeout of a particular request which is going out of ESB. In a particular  scneario, your client sends a request to ESB, and then ESB sends a request to another endpoint to serve the request. CLIENT->WSO2 ESB->BACKEND The reason for clients getting timeout is that ESB timeout is larger than client's timeout. This can be solved by either increasing the timeout at client side or by decreasing the timeout in ESB side. In any of the case, you can control the timeout in ESB using the below properties. 1) Global timeout defined in synapse.properties (ESB_HOME\repository\conf\) file. This will decide the maximum time that a callback is waiting in the ESB for a response for a particular request. If ESB does not get any response from Back End, it will drop the message and clears out the call back. This is a global level parameter which affects all the endpoints configured in ESB. synapse.global_timeout_inte
