Have you ever wondered what would happen if you mistakenly added bugs to your code and shipped them to users? For instance, let’s say an IT firm has its primary work tree on GitHub, and a team member pushes code with bugs to the primary work tree. The firm may also push the bug-infested software to users without knowing.
Users will complain to the firm about the bug, but the problems may take a while to fix, especially if team members don’t work on weekends. This act can earn companies a bad reputation, since it means customer needs go unmet.
So, which aspects of software deployment should IT firms be very mindful about?
Why is it necessary to be careful about the code that team members deploy? And how scalable can deploying code be? These questions may seem overwhelming. Join this ride to see how your organization can deploy code with the best results.
What Is Deployment?
Let’s say that your DevOps team works together on different sections of software. Maybe some team members work on the front end, others work on the back end, and still others validate and test code. Developers spend lots of time and energy to write code, test it, and make sure it’s clean.
However, developers can’t measure the performance of the software they’re building merely by looking at how clean their code is. What about API (application programming interface) endpoints?
How will developers make sure there are no broken links and the application works as expected on the targeted device or devices?
As a result of these uncertainties, code needs to be hosted on a target device or on servers online. What this means is that even as software developers have created workflows that make software development easier, testing the functionality of an application on a targeted device is still a priority in IT firms.
Software or application deployment simply involves making the software or application ready for use by hosting it online or on a target device. When an application is deployed online, users can access and use the software as long as they accept the firm’s terms and conditions.
An example is when the first version of GitHub was deployed in 2008; only then did users have access to use it. Firms can also deploy new features of an application online after first deploying it on target devices and testing it internally.
With test methods put in place and the use of different hosting services, IT firms can deploy continually and pay as they go, or they can choose to pay a fixed amount for a period of time.
What Deployments Tell Us About Enterprise Environments
Before we can fully understand what deployment tells us about an enterprise environment, let’s understand what an enterprise environment is. The term refers to the techniques, tools, and procedures an organization uses. For IT firms, it refers to all the processes and tools used during and after software development.
What, then, does software deployment tell us about the tools and processes that IT firms use? Why will IT firms use different deployment tools for their different applications? Let’s look at the life cycle of software and how deployment processes can make or mar software releases.
It All Starts With the Code
Of course, the first step to designing and building a computer program is writing code. The code software developers write makes up the software to be released. Most times, developers work on asynchronous development tools like GitHub and have to work asynchronously, sometimes remotely.
Because different team members work on different functionalities of the application, the team lead needs to monitor team members’ code. The reason firms ship software with bugs to users is that during this code tracking, some of the improper or bad code never gets caught. Therefore, firms need to monitor code before merging it with the primary code tree.
Testing and Debugging
Whether your organization uses Agile or DevOps, testing of team members’ code after they push it should be a priority. Testing code involves evaluating code to make sure they return the required results when executed.
Aside from testing code, developers test the functionality of the application. This type of test is to make sure software completes the tasks it’s supposed to.
Debugging is the next step after testing—fixing errors that emanate from testing. After this stage, the developer sees all the flaws, faults, and errors within the code. With Enov8 test monitoring tools, you can initiate testing of code while integrating it with tools like Borland, Splunk, and so on.
Building
After writing and testing code, you’ll need to compile and build it. Building code involves putting individual units of code together so that software runs properly. Most times, a single developer can build code using an IDE (integrated development environment).
Builds are usually pre-release software versions that only the software companies use. Developers need to deploy software to allow customers to use it. You’re probably wondering why developers need to deploy software before users can use it—after all, the act of building compiles the software.
Here’s the catch. For web applications, developers compile code and then install them in servers for global use. In contrast, for desktop applications, developers build code with build tools and then ship it to users with instructions on how to install or deploy it in the work environment.
Tools such as benchmark release management let organizations monitor and get metrics of the build process.
Deploying
After the build process, deploying software is the next step. Deploying usually involves installing software so people can use it on a computer or target device. Deploying can be done either on servers online or on a target device. It’s usually in users’ working environment.
Developers can also deploy software in their working environment to test software functionality. In this case, the developer is the user. All the processes for installing and running software in a specific environment are part of deployment. Software deployment is also related to software releasing because software releasing involves redeploying software with new features.
Redeploying and Maintaining
Software maintenance is almost synonymous with redeploying, in my opinion. This is because while maintaining software, developers correct faults, enhance UI/UX, and add new features. How will these new features get to users if developers don’t deploy them?
Redeploying involves pushing software code again after each change to reflect changes in users’ copies. Sometimes redeploying code is automatic, but it’s also possible to do it manually.
How to Scale Up Deployment
Deploying software shouldn’t be taken lightly. It delivers the software to users. A bad deployment can ruin the trust users have in the company. And what about the money it could cost your organization if software takes up unnecessary memory space on the server?
Let’s dive into the different methods to scale up deployment—the do’s and don’ts for a successful software deployment.
Step 1: Automate Testing
For a successful deployment, it’s essential to automate testing. The idea of waiting to compile code before testing is totally wrong because it eats up time. It makes sense to carry out tests after pushing code. This way, code that don’t pass tests won’t be accepted into the primary working tree.
DevOps teams can automate testing while working with distributed version control systems (DVCS) such as Git, GitHub, and Bitbucket. With this method, testing of code is continual, so you avoid the rush-hour testing of code.
Step 2: Automate Deployments with Continuous Integration and Continuous Delivery
To automate deployments, it makes sense to implement continuous integration and delivery. In continuous integration, when team members push code, the code undergoes tests and is added to the primary working tree. Delivery, on the other hand, means putting things in place to allow software to be released continually, anytime the team chooses. With this method, the DevOps team can minimize maintenance, maximize innovation, and reduce costs.
Continuous Deployment
There’s a thin line between continuous delivery and continuous deployment. In continuous delivery, the software is ready for release at any time. The act of releasing software to users continually is continuous deployment. With continuous deployment, teams can add new software features, remove bugs, and ship to users swiftly.
Containerization
Bugs used to show up when developers coded in one environment and deployed to another environment. Now, developers can compile code and related files and dependencies they require to run in different environments, bug-free.
This method allows software to behave similarly in different operating systems. To use this method, DevOps teams use tools such as Docker, Kubernetes, and so on.
Step 3: Monitoring Deployment
Scaling deployment doesn’t stop at deploying your software. You’ll need to monitor the performance of software after deploying. Also, you’ll need to manage and add new features after deploying (or redeploying).
How do you ensure deploying doesn’t fail? What measures do teams need to put in place? With test environment management tools, monitoring software is efficient even after deployment.
