Software Development Lifecycle
The software development lifecycle (SDLC) is the cost-effective and time-efficient process that development teams use to design and build high-quality software. The goal of SDLC is to minimize project risks through forward planning so that software meets expectations during production and beyond.
VBJ SDLC phases:
Plan - The plan phase typically includes tasks like cost-benefit analysis, scheduling, resource estimation, and allocation. The development team collects requirements from several stakeholders such as customers, internal and external experts, and managers to create a software requirement specification document.
Design - In the design phase, software engineers analyze requirements and identify the best solutions to create the software. They will look at how to best integrate the new software into any existing IT infrastructure the organization may have.
Implement - In the implementation phase, the development team codes the product. They analyze the requirements to identify smaller coding tasks they can do daily to achieve the final result.
Test - The development team combines automation and manual testing to check the software for bugs. Quality analysis includes testing the software for errors and checking if it meets as per requirements.
Deploy - Develop software code and test on a different copy of the software than the one that the users have access to called production, while other copies are said to be in the build environment, or testing environment.
Maintain- In the maintenance phase, among other tasks, the team fixes bugs, resolves customer issues, and manages software changes. In addition, the team monitors overall system performance, security, and user experience to identify new ways to improve the existing software.

.NET Applications:
VBJ .NET Framework is part of the .NET platform, a collection of technologies for building applications but not limited to websites, services, desktop apps, and more on Windows. .NET Standard is a formal specification of the APIs that are common across .NET implementations. This allows the same code and libraries to run on different implementations. VBJ works on .Net Common Language Runtime (CLR) is the execution engine that handles running applications. It provides services like thread management, garbage collection, type-safety, exception handling, and more. The Class Library provides a set of APIs and types for common functionality. It provides types for strings, dates, numbers, etc. The Class Library includes APIs for reading and writing files, connecting to databases, drawing, and more.
DevOps:
VBJ DevOps use as a set of practices and tools, DevOps integrates and automates the work of software development (Dev) and IT operations (Ops) as a means for improving and shortening the systems development life cycle. It a combination of cultural philosophies, practices, and tools that increases an organization's ability to deliver applications and services. Our DevOps team includes developers and IT operations working collaboratively throughout the product lifecycle, in order to increase the speed and quality of software deployment.
Benefits of DevOps:
Speed - Move at high velocity by that innovate for customers faster, adapt to changing markets better, and grow more efficient at driving business results.
Rapid Delivery - Increase the frequency and pace of releases so that more be can innovate and improve product faster. The quicker product would be release new features and fix bugs, the faster can respond to customers needs and build competitive advantage.
Reliability - Ensure the quality of application updates and infrastructure changes so that reliably deliver at a more rapid pace while maintaining a positive experience for end users. Use practices like continuous integration and continuous delivery to test that each change is functional and safe.
Improved Collaboration - Build more effective teams under a DevOps cultural model, which emphasizes values such as ownership and accountability. Developers and operations teams collaborate closely, share many responsibilities, and combine their workflows. This reduces inefficiencies and saves time reduced handover periods between developers and operations, writing code that takes into account the environment in which it is run.
Fullstack Development:
Full stack development refers to the end-to-end application software development, including the front end and back end. The front end consists of the user interface, and the back end takes care of the business logic and application workflows.
