Non-readable code? Non-practical architectures? Unclear requirements? Are you pulling your hair at this point?

These are exactly the sort of pitfalls this course serves to provide in-depth remediation for. Over your years of working in the software industry, numerous day-to-day challenges like these come and go. While the industry has been constantly transforming, some core principles and values remain amidst the advancing technologies. 

Through tried and tested approaches, you will learn how to practically implement 'Effective Software'. With a comprehensive compilation of key concepts in software development methodology, you will be left with essential techniques for becoming a better software craftsman. It is time to distinguish between the core and the noise, making your skills timeless!

Effective Software Development for Enterprise Applications

Deploying software systems is a task of DevOps and CI/CD processes. Interestingly, it is easier to deliver some programs to the hosting environment than others. What makes the difference? Besides the configuration of deployment pipelines, the architecture of applications also affects results. Therefore, I want to discuss a couple of topics in this lesson that you need to consider when architecting software. These points will either enable or hinder your ability to quickly and adequately deploy applications.


# Versioning

An application needs to evolve in versions as a cohesive unit that includes both code and the corresponding database. You should install or uninstall a version when necessary to go to the next or previous working snapshot. 


To achieve this objective, you must plan for the evolution path of the application.

Earlier in this course, I briefly explained the necessity to version the application database, so I will not cover that topic again. This time, let us focus on the versioning of the application.

It is easy to forget about the evolving nature of an application in the middle of development. You add new features to the system and modify existing capabilities, almost like a routine. When you try to take the program to a production environment, you realize what is there currently and what you are trying to do with it. If you do it right, your application does not need to have any downtime affecting customers who try to place an order or explore your products online. If the move to a new version is complicated or confusing, your customers can notice glitches impacting their satisfaction. It is easy to avoid complications if you are ready for production deployment exercises at all times.

The first step for readiness is to mentally realize that *deployment is going to happen no matter what*. Next, force yourself into building chunks of self-contained features that move a system from one working state to the next working state, i.e., from one version to the next. *Repeat this exercise for every change*. If each small increment achieves this objective, then the entire release should also guarantee evolution to the working state or back if something goes wrong. This shift of mindset is a fundamental breakthrough that puts you on the right track to having successful product releases. As you noticed, one simple idea behind this process is versioning.

>Therefore, plan for versioning when architecting and implementing software systems, as this technique can be the deciding factor of successful or failed production deployments.

I recommend that you look for additional reading material about the versioning of various deployable units, such as for database, API, and other constituents of your systems. For example, see [Versioned Databases](https://www.tutisani.com/software-architecture/versioned-databases.html), [Switching to Versioned Databases](https://www.tutisani.com/software-architecture/switching-to-versioned-databases.html), [Versioning Shared Database](https://www.tutisani.com/software-architecture/versioning-shared-database.html), [Merging Versioned Databases](https://www.tutisani.com/software-architecture/merging-versioned-databases.html), and [REST API Versioning](https://restfulapi.net/versioning/).
