Linear Regression under the hood using Matlab
Sometimes to choose the appropriate model, the suitable training algorithms, and the hyperparameter to best fit the task as well as to debug issues and perform error analysis more efficiently, it is necessary to understand what is under the hood when applying Linear Regression. Hence, in this post, we will dissect the implementation of linear […]

Invoking SOAP Services using SoapUI – Basic Authentication, Part I
In this series divided into three-part, I will demonstrate how to use the SoapUI API tool to invoke a secured WCF SOAP service. The first post will focus on creating a service where it will be the system under test. The second post will approach the steps required to invoke it while secured by a […]

Microservices in Publish-Subscribe Communication.
Publish-Subscribe Messaging systems play an important role in any microservices enterprise architecture as it enables reliable integration without tightly coupling the applications. The ability to share data between decoupled systems is not a problem that is easily tackled. Consider an enterprise with multiple applications that are being built independently, with different languages and platforms. It […]

Key Java @annotations to build full Spring Boot Rest API
This post aims to demonstrate key Java @annotations used to build a functional Spring Boot Rest API. The use of Java annotation gives developers the capability to reduce the code verbosity by a simple annotation. As an example, we can refer to a transaction. By the standard programmatically process with a transaction template, this requires […]

WCF Transport Security with Certificate Authentication
This post demonstrates the use of X.509 certificates for server and client authentication when using WCF transport security. This security mode is ideal for communication between applications in the intranet network. Our demo creates a service that will implement a simple, repeated string algorithm. In this scenario, the service is hosted under Internet Information Services […]

Invoking SOAP Services using SoapUI – Basic Authentication, Part II
In the first post of this series, we created a basic authentication service to be invoked using SoapUI. Therefore, in this second post, we will demonstrate step by step how to use this tool to successfully invoke this kind of service. 1-Basic WCF SOAP using SoapUI – Create a New SOAP project Firstly we need […]

SOA and process services integration
Service-oriented architectures (SOA) have brought significant gains for process automation. According to the official definition of OASIS [1], it is a paradigm for organizing and utilizing distributed resources that may be under the control of different domains of ownership. Although the official definition may be ambiguous, it is possible to define SOA as a paradigm […]

Microservices Security Mechanisms
Within the universe of microservices security mechanisms, the access to information or resources “on behalf of”; allows third parties (a particular application or service) to communicate with other applications or services, acting on behalf of, and not while the application or service. Authorization to third parties using the traditional model, where the client accesses a […]

Workflow Systems – Integrated and Independent Systems
Traditionally, systems are designed and implemented not only by procedural codes but also by the processing logic performed by the application, expressed as workflow. Having a system where business logic is implemented using procedural or functional codes has consequences, wherein increasing complexity and demand to adapt them to new requirements, any process modification requires code […]
