CockroachDB: The Distributed Database Solution of the Modern Age

ISSUE:13
 

Due to the inability of existing database systems to provide the features required by modern applications, NewSQL database systems have been developed. This new approach combines the ACID guarantees and query language flexibility provided by traditional databases with the scalability, ease of distribution, and fault tolerance features of NewSQL database systems. CockroachDB, as a concrete example of the NewSQL concept, is designed to meet these demands with its powerful features, standing out as a distributed architecture database solution. In this article, we delve into the features, advantages, and potential application scenarios of CockroachDB in detail.

Transformation from Monolithic Architecture to Microservice Architecture

ISSUE: 11
 

Monolithic architecture has served as a defining model of software development for many years and has been used successfully in many projects. However, in an age where technology is evolving rapidly, organisations need to develop in a more agile, scalable and rapid manner. In this issue of the series, the challenges faced in the transformation from monolithic architecture to microservice architecture and the solutions to these challenges are discussed.

Foundations of Microservices Architecture

ISSUE: 10
 
Microservices architecture represents a significant transformation in the approach to developing and managing large and complex software applications. By breaking down software applications into small and independent services, it operates each as a separate microservice. Microservices are typically distributed using lightweight container technologies, enabling rapid scalability. This study discusses the fundamental concepts, advantages, costs, and implementation of microservices architecture.

Integration Test Writing Techniques with Testcontainers

ISSUE: 09
 
Integration tests are essential types of tests in projects. They ensure that independently developed parts of the system are tested together in an integrated manner to ensure the correctness of their communication protocols. However, integration tests can easily be influenced by external factors, leading to incorrect negative results. This situation can decrease confidence in integration tests over time and may result in the oversight of real errors. The purpose of this study is to demonstrate the general working logic, scope, and how to use the Testcontainers library in integration tests written in Java, facilitating the integration testing process.

Cloud Usage

ISSUE: 07
 

The increasing importance of software technologies and the use of applications developed with these technologies have also increased the requirements for information technology infrastructure for these applications. These requirements vary in terms of cost, capacity, security, and other factors depending on the type and usage of the developed application. Software organizations, while managing their own IT infrastructure, are faced with the problem of not being able to meet these needs and, as an alternative solution, encounter cloud computing systems. In this study, the problems faced by organizations that do not use the cloud are categorized and exemplified.

Comparison of REST API and gRPC Architectural Styles

ISSUE: 06
 

gRPC and REST API are two different architectural styles commonly used in modern application development. While gRPC, developed by Google, is focused on performance and efficiency, REST API is a more generic architecture built on usability and simplicity. gRPC converts data into binary format using a serialization format called Protobuf, enabling high-speed communication with low memory usage. REST API, on the other hand, usually uses the JSON format to transfer data.
The purpose of this paper is to guide the reader in choosing the right architectural style by considering factors such as application needs, performance, data integrity and platform independence.

Spring Framework

ISSUE: 05

 

Spring Framework is an open source development platform that provides comprehensive infrastructure support for developing Java applications. It has recently increased its popularity among current technologies and has become one of the most preferred application frameworks.
Spring Framework is recognized as one of the most important tools used when developing applications in Java language. This framework aims to eliminate the difficulties often encountered during the development of Java applications. It facilitates the process and stages of application writing by eliminating the effort of writing the entire program code from scratch.
Within the scope of this study, topics such as Spring Framework concepts, features, areas where it can be used, what can be done, and preferences are discussed in general.

Use of Authentication Engines

ISSUE: 04


There are many technologies for user authentication and authorization. These include Apereo CAS, Keycloak, Gluu, Okta, Shibboleth, WSO2, AWS Cognito. In this study, Apereo CAS and Keycloak technologies, which provide secure single sign-on (SSO) services for web-based applications due to their open source, extensibility and scope, are examined. Alternatives for user login and authorization technologies, which are an important part of software projects, have been researched and the integration of these alternative technologies with the Spring Framework has been tested. This study is handled in a framework that can be used by all public institutions and private sectors that want to add a security layer to their software projects.

Micro Frontend Architecture

ISSUE: 03

 

We live in a period when the world is increasingly digitalized and everything is transferred to the virtual environment. The changing desires of end users over time have led to different needs, different needs have led to new technologies, and new technologies have led to the realization of software projects that meet these needs. New technologies and architectures have developed and are constantly evolving in order to make digital transformations easier in a productive cycle. Microservices and micro frontend architectures, which have become very popular today, have emerged as a result of this cycle. In this study, micro frontend architecture, which enables large and complex projects to be created in a more sustainable way with lower costs, is analyzed.

CI/CD Process Management

ISSUE: 02


Recently, the software development sector has been undergoing a slow but real transformation. While software is increasingly becoming a part of everything, software developers are trying to cope with this increasing demand through more automation. Due to the high demand for the rapid deployment of new features and applications, the principles of Continuous Integration (CI) and Continuous Delivery (CD) have become increasingly and more effectively used. The aim of this study is to overcome delivery problems by improving the delivery timeline, test load steps and benchmarking tasks with the CI/CD pipeline approach.
