Deploy is a well-known term among web developers. It can mean many things, depending on the environment and technology used. However, the meanings that most closely relate to the practice and summarize its function are: deploy, deploy, enable, or simply publish .
This activity has evolved significantly over the decades. Initially, deployment was carried out at a slower pace because progress was primarily manual. With technological advancements, it is now possible to do so automatically, improving the user experience and speeding up the delivery of results .
In this article, we’ll show you some deploy examples to make it easier to understand. You’ll also learn the three possible ways to deploy it.
Excellent reading!
What is deploy and what is it for?
In general terms, the word “deploy” is used to describe something being placed in its current location. It’s also used when a system is enabled for use, whether in a development , testing, or production environment.
Imagine you’ve created a website on asia mobile number list your computer and left it static and unpublished. When you upload your site to a web hosting server , this process will be considered a deployment.
Another example is when a new version of a program is generated, and the developer wants to deploy it to an application server. That is, upload the updated files to a web server, which can be a testing or production environment. This also involves performing a deployment.
Attention : Do not confuse the term implant with implement, as they are two very different things!
When we say “implement,” we mean starting something, while “implement” is the act of putting something into practice. If we apply this to the world of programming, when the development of a system begins, it is being implemented. The moment the project begins to be used by users, we can say it has been implemented.
What are the ways to deploy?
As we mentioned before, the system deployment process has evolved significantly over the past few decades. Today, there are basically three ways to do it:
1 – Manual
An example of this process is File Transfer Protocol, also known as FTP . This is a type of connection that allows two computers with how to control business analytics to continue growing internet access to exchange files. The process is performed manually, so it requires a person in charge.
Another way to do a manual deployment is when you need to change a small detail in your JS file and you upload it to production.
2 – Partially automated
An example of a partially automated deployment is pushing the master branch to the Git repository, which triggers a small hook and updates the web hosting server. Although it requires a few commands, the process is automated. Its advantage is the ability to control the version and status of each deployment.
3 – Fully automated
This is the latest trend in web development. It not only automatically copies changes to the server, but is also closely connected to the concept of continuous integration .
In addition to copying, continuous deployment offers many advantages, as it makes it possible to work on changes, or integrations, made by different programmers.
The deployment tool, in this case, performs all the necessary tests to ensure smooth integrations from production. The possibilities are endless, from:
- Update libraries;
- Test server connectivity;
- Simulate visits and data entries.
All of this is done automatically, and if any errors occur, the deployment can be rolled back.
One of the most popular tools for automated deployment is Jenkins . Among its benefits, the following stand out:
- High level of productivity;
- Security;
- Quality in software development
Strategies that can be used to deploy
There are three very simple strategies that can be implemented and that allow for deployment on a daily basis:
1 – Rolling
It involves upgrading the services fax list with the new version of the code. Thus, the old version is completely replaced; however, this will happen when the new version is ready to run. The deployment is then done gradually ; while the new version is not yet 100% complete, it can coexist with the old one.
2 – Blue-Green
It is characterized by having two identical environments , known as mirrors , which have a load balancer, thus allowing traffic to be redirected to the desired environment.
The benefit of this strategy is that it’s possible to upload a new version of the application that’s in production, while the current version ( blue ) only receives requests. This way, as soon as testing is completed on the new version ( green ), it’s possible to make other requests targeting the new version.
The strategy allows for testing in production , before users have access to the service.
3 – Canary
This is the most complex strategy that can be used. It involves placing the new version into production for a portion of users. It’s possible, for example, to release a feature only to the male audience under 30 years old.
The interesting thing about this format is that you can test the new version in practice, as well as monitor user feedback before releasing full access.
