The steps to build a Karaoke app
We now take a detailed look at how to make a Karaoke app. Such a project involves the following steps:
1. Agree on a project scope
I suggest the following scope for this project:
- Web app development;
- Android app development;
- iOS app development.
You should include the features I have suggested.
2. Choose a project methodology
After launching an initial version in the market, you will likely add features based on the market response. You might even want to target smart TV platforms or expand into other geographies.
Such projects are good candidates for Agile methodology, and you can read “Waterfall vs Agile: which methodology is right for your project” to understand why. We call the initial version a “Minimum Viable Product” (MVP) in the Agile parlance.
3. Onboard a project team
Your project team needs the following roles:
- Business analysts (BAs);
- UI designers;
- Web developers with experience in Node.js;
- Android developers with Kotlin expertise;
- iOS developers with Swift skills;
- A project manager (PM).
I recommend that the PM manages this project using the “Scrum” technique, which is useful for Agile projects. Here, the iterations are called “Sprints”, and the PM acts as the “Scrum master”.
The scrum master forms cross-functional, small teams that are called “Scrum teams”. You can consult our guide “How to build a Scrum development team?” for more insights.
4. Prepare a development strategy
Your development strategy for this project should comprise the following:
- You should use managed cloud services providers. This will enable you to focus on the development, and you won‘t get bogged down with infrastructure management.
- Consider using market-leading “Software Development Kits”(SDKs) and “Application Programming Interfaces” (APIs) for key features like accessing music, streaming, video recording, in-app purchase, payment gateway integration, etc. This way, you don‘t “reinvent the wheel”.
5. Procure managed cloud services for web app development
Several noted managed cloud services providers offer “Platform as a Service” (PaaS) for web app development. I recommend that you use one since it offers the following advantages:
- PaaS providers manage the entire gamut of cloud infrastructure, including servers, networking, storage, etc.
- They provide the operating system (OS), middleware, and runtime environment. This enables you to focus on coding.
- PaaS providers offer “Application Performance Monitoring” (APM), auto-scaling, DevOps, databases, and several other services.
- You can easily integrate 3rd party APIs with your app when you a PaaS platform.
Our guide “10 top PaaS providers for 2019” explains these advantages in detail. AWS has impressive cloud capabilities, therefore, I recommend that you use AWS Elastic Beanstalk, i.e., their PaaS offering.
6. Get managed cloud services for the mobile app backend
The development and ongoing management of mobile backend take time and energy, however, you can use a “Mobile Backend as a Service” (MBaaS) to simplify this. MBaaS providers offer many advantages, e.g.:
- They handle the cloud infrastructure fully, including networking, server, and persistent storage.
- Scaling your Karaoke app will be easier with an MBaaS platform.
- You can easily implement features like user management, security, and push notifications if you use an MBaaS platform.
- Integrating 3rd party APIs, and managing the complexity due to various mobile platforms and devices become easier with an MBaaS platform.
Read “How to choose the best Mobile Backend as a Service (MBaaS)?” to learn more about these advantages. You can use AWS Amplify, which is the MBaaS offering from AWS. You need only one AWS account to use Amplify and Elastic Beanstalk. You also don‘t need to hire mobile backend developers and cloud platform architects.
7. Sign-up for Spotify SDKs/APIs
You need to provide a wide range of songs to your users. Spotify is a good solution. They offer the following features and advantages:
