Deploy Explained: Step-by-Step, Methods, and More!

Deploy is one of the most important stages of systems development. This is because it is in this phase that the programmed idea is applied to different devices.

For this reason, many developers feel apprehensive when it comes to making a deployment.

In this article, we will seek to clarify everything about what deploy is so that it is not a task that causes so much dread.

Enjoy the read!

What is deploy?

Deploy is a term used in other areas of knowledge, but its use is predominant in the Information Technology (IT) universe.

Deploy is, basically, that moment when the developed software is put into production.

In the past, this action was much more difficult to perform. However, with today's existing technologies, deploying is faster and more automatic.

In practice, deploy is that moment when you implement your site for external and public use.

Before, this system was only on your machine, but now other people will be able to try it out.

Beyond what deploy is, understand how it works

Below, we will explain a basic guide on how to start your deploy project. Check out the step by step:

Plan the deploy

First, it is necessary to plan the deploy very well. For this, it is necessary to choose some environment to apply your code.

You can opt for a small server, some hosting or even a PaaS (Platform as a Service) platform.

This choice is quite open, because the only condition is that the environment supports your deploy, as well as accepts the programming languages you are using.

Additionally, it is necessary to organize the domain of the site where you want to test your deploy. For this, purchase a domain.

There are several platforms that sell domains, each with specific features and prices. For this reason, our tip is to think about the best cost-benefit.

After purchasing the domain, do not forget to configure the DNS (Domain Name System) according to your server or hosting.

This is important so that the domain recognizes your server.

Develop

It is time to start developing the code, after all, you need to have something to implement.

If you already have experience with development, make your project for testing.

Otherwise, it is possible to implement your first code, also called "Hello World".

It is important to work with version control. One of the most popular is Git. If there is any problem in some version, it is possible to go back, very easily, to the previous version.

Perform the necessary tests for the deploy

Test your deploy beforehand before starting the implementation.

For this, it is recommended to rest a little from the project and then come back to review it. This makes it easier to notice inconsistencies.

Adjust all necessary settings and start the process.

Implement the deploy

Now is the time to implement your deploy. Carry out the activity the way you learned, as the activity can be performed in different ways.

A golden tip is not to perform the implementation on the last day before your day off.

This happens because, if your deploy presents an error, no one will be available to solve the problem.

The situation becomes even more chaotic if you test a deploy directly on a client's website. You can be sure, they will notice quickly and you will have to work overtime.

Monitor and optimize

This is the most important process. When the code is already applied, monitor its functioning.

Additionally, test all possible functions of it to see if everything works correctly.

In case of errors, take the application offline and fix the related codes.

Did you understand what deploy is? Learn about the ways to perform it:

There are several ways to make a deploy. Below, we present the main ones:

Learn what automatic deploy is

This is the most optimized and complete deploy that exists today. This type of deploy is capable of copying the changes to the server.

Additionally, automatic deploy is responsible for facilitating what we call continuous integration.

It is possible for several programmers to work on the same project and have all those optimizations updated automatically.

Learn what partially automatic deploy is

A partially automatic deploy requires manual actions from some developer, but the update is performed automatically by the server.

Learn what manual deploy is

Manual deploy is the most classic type of deploy. For this reason, most experienced developers prefer it.

An example of manual deploy is the File Transfer Protocol (FTP), which facilitates the exchange of files between two computers.

This process is performed manually, by one or more professionals.

The most basic way to perform manual deploy is when you edit the code and insert it into production.

Strategies for deploy

There are some strategies for the process of implementing your code. Check out 3 of them:

• Rolling - This is the strategy of rolling out the new services to the new code one at a time. This way, the old version should only be discarded after the entire new one is ready.
• Blue-Green - Blue-Green is a strategy where there are two identical environments, also known as mirror. All updates occur in the editing version, called blue. After finalization, it is possible to send all modifications to the green version, which is the new one.
• Canary - This is the strategy that allows displaying the service to a small number of users, who can still be defined by characteristics, such as gender and age.

The Linux operating system is quite optimized for software development. However, many people do not master it.

Conclusion

Before learning to execute, you need to learn the theory. In this blog, we raised quite interesting points about what deploy is.

The important thing in IT is to always study. Many techniques are updated and it is necessary to be on top of most of them.

Here you could notice how to organize your deploy process in steps, in addition to seeing that there are other ways to perform it.

Seek to deepen these variations, as your deploy tends to be increasingly accurate.
