Are you thinking about developing a cloud-based application to power your SaaS product? If not, then you should.
The cloud industry has been expanding at an astonishing rate, and it is clear that it is the path of the future. The scale of cloud computing has skyrocketed beyond expectations. One 2021 projection predicted the market would reach $168 billion by 2025—but in reality, it’s surpassing $600 billion a full year earlier.
The hat can be tipped to AI for this explosive growth of course. But, the cloud infrastructure needed for AI benefits the cloud as a whole. That means this monumental drive to create the resources for a full AI takeover will be ready for you when the hype dwindles—or AI takes over and everything is way more efficient and we can all go on vacation.
What is clear with this trajectory is that cloud technology is projected to become a business necessity by 2028. That’s big!
This means there’s no better time to consider building (or transitioning to) a cloud-based web or mobile application. However, to succeed, you need to approach cloud app development the right way. That's where this guide comes in. We’ll walk you through the entire process, covering the best practices, development approaches, and what makes cloud application development different from traditional methods. Let’s dive in.
What is cloud application development?
Cloud application development covers building and deploying mobile or web apps on cloud infrastructure. It also involves hosting and managing building apps with cloud technology. You can get cloud hosting services from top providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform.
Cloud technology is infrastructure for storing and accessing programs or data via the internet—instead of relying on physical on-premises computers or servers.
The process of developing cloud-based apps typically requires using cloud-based tools and services to build, test, and deploy the application. The process may involve leveraging back-end programming languages like Python, Java, and PHP or web technologies like HTML, CSS, and JavaScript. The top cloud app development teams use DevOps practices and tools like Kubernetes.
Approaches to cloud-based application development
Multiple approaches exist for developing cloud-based applications. The top six approaches are:
Infrastructure as a Service (IaaS): IaaS offers virtualized computing resources, such as virtual machines, storage, and networking. Developers can use these virtualized resources to quickly build and deploy software and scale their application infrastructure when necessary. The primary difference between IaaS and other approaches is that IaaS provides greater flexibility and control over operating systems.
Platform as a Service (PaaS): PaaS involves a third-party cloud services provider (such as Heroku) offering developers a complete development and deployment platform. Developers can use the platform to access the hardware, software, and middleware they need to build and test cloud-based apps. The primary benefit of this approach is it allows users to focus on development and deployment instead of infrastructure management.
Software as a Service (SaaS): The SaaS approach gives developers access to pre-built software applications via the internet. Developers don’t have to build apps from scratch because they can use existing software and tools to create a SaaS application.
Functions as a Service (FaaS): FaaS is also known as serverless computing. It allows developers to write and deploy individual functions that execute in response to specific events. The key here is that this is done without needing to manage the underlying server infrastructure. Cloud providers (like AWS Lambda) automatically scale the execution of these functions based on demand. The primary advantage of FaaS is that developers save money by only paying for the execution time of their code.
Containerization: Containerization involves packaging an application and its dependencies together in containers—allowing the app to run consistently across different environments. Tools like Docker and Kubernetes are popular for managing and deploying containerized applications. The main benefits of containerization is that it allows developers to manage application infrastructure more efficiently, provide flexibility and scalability across cloud environments, and it gives teams more control over their deployments.
Hybrid cloud development: Hybrid cloud development involves combining on-premise infrastructure with cloud services. The combination allows businesses to leverage the flexibility of cloud computing while maintaining control over certain critical resources. This approach is ideal for organizations with regulatory requirements or existing on-premise systems that can’t be fully migrated to the cloud. Hybrid cloud solutions thus allow teams to scale applications using cloud resources while maintaining sensitive data or legacy systems on their private infrastructure.
In short, PaaS is best for developers who want to focus on application development without managing infrastructure, while SaaS allows them to use pre-built software. IaaS offers more control and flexibility, making it suitable for large-scale applications that need custom infrastructure management.
For event-driven apps, FaaS provides a cost-effective, serverless option where developers only pay for the execution time of their code. Containerization ensures consistent deployment across environments, offering flexibility and scalability. Finally, hybrid cloud development is ideal for businesses that need to combine cloud scalability with on-premise control. Each approach has unique advantages depending on your application's needs and goals.
How does it differ from other types of app development?
Cloud based application development differs from other forms of app development. Native apps are built for specific platforms like iOS or Android, while web apps run in a browser using technologies like HTML, CSS, and JavaScript. Hybrid apps blend both approaches, working across multiple platforms.
Cloud apps combine all these, allowing users to access them on any system—macOS, Windows, iOS, or Android—either through a browser or an installed app, as long as there’s an internet connection.
Cloud app development vs. traditional app development
Other differences that set cloud-based application development apart from other forms of app development are:
Easier deployment: Traditional developers typically code and deploy in different environments, which can be time-consuming and expensive. Instead of developing apps on local machines and deploying them elsewhere, cloud developers build and deploy in a cloud environment. Doing so eliminates the hassle of multiple entries, compatibility issues, lost data, and more.
Agile and DevOps software development: Cloud developers use agile and DevOps software development methodologies that facilitate collaboration between development team members. The collaboration leads to more efficient product development. Also, agile processes require frequent iteration and user testing.
Infrastructure: Unlike traditional app development, cloud app development does not require building and maintaining your own physical infrastructure. Relying on cloud computing infrastructure can help you save time and money and facilitate scalability during development.
Cost efficiency: With cloud app development, you only pay for the resources you actually use. There's no need to buy expensive hardware upfront or deal with maintenance costs later on. Traditional app development, on the other hand, often requires investing heavily in on-premise infrastructure and dealing with ongoing upkeep.
Updates and scaling: Cloud platforms handle updates and scaling automatically, so you don’t have to worry about managing upgrades or purchasing new hardware when traffic spikes. With traditional development, scaling usually involves manual intervention and costly hardware upgrades.
Global accessibility: Traditional apps are typically tied to specific locations which limits access and makes collaboration more difficult. Alternatively, cloud apps are available anywhere you have an internet connection. This makes working with distributed teams or remote employees totally feasible.
Continuous integration and continuous delivery (CI/CD): Cloud development often uses CI/CD pipelines, so new features and fixes can be rolled out quickly and frequently. Traditional development tends to follow longer, more rigid release cycles, making it harder to push updates regularly.
In summary, cloud application development has a more efficient and flexible building and deployment process than traditional app development.
Benefits of app development in the cloud
The primary benefit of building apps within a cloud environment is developers can do away with physical on-premises hardware and servers. This results in:
Enhanced scalability: Cloud computing helps developers scale applications up or down as necessary. The ease of scaling ensures applications can always access computing resources to run smoothly as user traffic rises and falls. Also, developers can use technologies like containers and microservices to develop more scalable software solutions.
Improved flexibility: Cloud-native application developers can work from anywhere if they have an internet-connected device. The flexibility facilitates collaboration and productivity as developers can make changes and view updates from anywhere.
Cost-effectiveness: Cloud app development does not require investing in on-premises infrastructure, making it cheaper than traditional app development. Also, easy access to cloud resources facilitates experimenting with new ideas and prototypes without incurring significant upfront costs.
Improved performance: Cloud-based applications can run faster and more efficiently than on-premises applications. It's thanks to cloud providers having data centers (server farms) that provide as much computing power and resources as the app needs.
Enhanced security: The top cloud services providers offer robust security measures and data protection, including encryption, backup, and recovery services. These security features can safeguard your cloud-based app against cyber threats and crashes.
Easy integration: Cloud apps can integrate with other cloud-based services through APIs. Integrating with other systems helps developers build more complex and powerful applications with less effort and time.
Easy upgrades: Cloud app developers can automate multiple developments and testing routines to improve cloud software. Also, development approaches like DevOps allow cloud app developers continuously improve software and deploy updates to benefit end users.
Cloud app development challenges
While cloud application development has several advantages, it’s not perfect. Some of the challenges faced by cloud app developers include security challenges. Choosing the wrong cloud service provider can put you at risk of cyber-attacks. Other problems you may experience are scalability and integration issues.
Also, cybercriminals tend to target a third-party app’s API. So, even if your cloud app is secure, cyber attackers may gain access through the API of a compromised third-party app that a user integrated with your software.
Cloud application development best practices
Following cloud application development best practices will help your developers deliver a reliable, scalable, valuable, and secure finished product. It also minimizes the risk of errors that may compromise your app development process. Below are the most important best practices to incorporate into your cloud app development process:
1. Design for scalability
Cloud application developers must put in place measures that ensure apps can scale easily to accommodate changes in demand. Some of these measures include designing applications with a distributed architecture. The distributed architecture will enable an app to run on multiple servers, utilize cloud services, and automatically scale resources as needed.
2. Minimize time-to-market
Time-to-market is the period from ideating a product to launching the finished product. A short time-to-market lowers app development costs because developers charge more the longer a project takes. Also, the sooner you launch a product, the sooner it can start generating revenue.
Equally important, a short time-to-market allows for quick testing and early feedback. Your team can use the feedback to optimize your app’s performance and make it more attractive to end users.
Reduce time-to-market by first releasing a minimum viable product (MVP). An MVP is not a completed product, but it will have your product’s core features and closely simulate how your final product will look and perform.
With this iteration of your app, you can collect user feedback to gauge your cloud-based app’s value. As we’ve mentioned, you can also use the MVP to gather valuable user insights you can apply to improve your product’s value, performance, and attractiveness.
3. Fast iteration
Fast iteration means developing and releasing new versions of your app quickly, allowing you to gather and implement user feedback more efficiently.
For example, after releasing a version today, users can provide input, and within a month, you can launch an updated version with the requested changes. This cycle continues, helping you create a product that’s valuable to users. And, it shortens the development timeline and saves resources by focusing on relevant improvements.
4. Prioritize security and automate
DevOps practices suggest automating building, testing, and deploying cloud-based applications. Automation eliminates manually entering code, minimizing the risk of human error. Avoiding human error during cloud application development can fast-track the process and facilitate getting the best results.
Also, reducing human error can prevent performance issues and vulnerabilities that cyber attackers can exploit. Further prioritize security by incorporating encryption, access controls, and other security measures into the app. Doing so will minimize the risk of unauthorized access and protect sensitive data.
5. Have a performance monitoring and disaster recovery plan
Developers should continuously monitor cloud-based apps during the development process. Doing so will help verify if the app is performing as expected. It also enables developers to identify and rectify bugs and other issues quickly. Several performance monitoring tools are available for identifying app performance issues in real-time.
Lastly, developers must put in place disaster recovery measures. Such measures will prevent having to start product development from scratch if a catastrophic event occurs. Effective disaster recovery measures include regular backups and failover procedures that facilitate recovering saved progress.
Process for cloud application development
Cloud application development processes typically vary between app development teams. Also, developers may need to tailor app development processes to match a client's unique needs. Regardless of the differences in processes, developers must still pass through these stages during cloud application development:
Stage 1: Ideation
The stage involves you and your team coming up with an idea for a cloud-based app. The trick to creating a multi-million dollar idea is first identifying a problem (or problems) you can solve with your app. The problem must be recurring and long-term. Otherwise, your app will become obsolete within a few years because the problem it solves no longer exists.
Also, the problem should be widespread, meaning several people experience it and want a solution. The more widespread the problem is, the more potential users your app will have.
How do you generate ideas for your app? You could start by looking inward to identify problems you or someone close to you needs to solve. Alternatively, look outward by researching competitors within your industry or your target audience to identify gaps in existing products. You can also visit forums like Reddit or Ask Product Hunt to see problems discussed by consumers.
Stage 2: Screening
During the ideation stage, you identify multiple problems to solve with an app. Once you’ve shortlisted ideas, next is the screening stage.
Screening is where you look at your ideas to identify the right one to pursue. The best idea to pursue is one that checks these boxes to the highest degree:
Fits your long-term business goals
Has a clearly defined market (people who need the solution)
Solves a specific problem(s)
The idea should also be scalable and have clear development costs.
Stage 3: Concept Development
Once you’ve settled on an idea, manifest it by developing a concept for your app. The best way to start this is to build a low-fidelity prototype. A low-fidelity (lo-fi) prototype is a rough sketch of your app's look and user flow. Below is an example.
You can also use the prototype to map out user flows. Showing the prototype to your app development team will give them a clear picture of how you want your app to look. You can also show the prototype to stakeholders and potential users to get valuable feedback regarding the product's viability.
Stage 4: Select Cloud Hosting
Cloud-based apps need cloud hosting to provide the resources that keep them running smoothly and accessible. Popular platforms include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, which offer public, private, or hybrid cloud options.
Private cloud hosting: This hosting gives you exclusive access to a data center, offering more control and security, but it's expensive and typically used by large organizations.
Public cloud services: This option is more affordable, highly reliable, and scalable, with the provider managing the infrastructure.
Hybrid cloud: Hybrid options combine both, allowing sensitive data to be stored privately while leveraging public cloud resources for scalability.
Selecting the right one depends on your size and needs, but for most the public option is sufficient
Stage 5: Product Development
Once you’ve settled on a host and cloud application development platform, you can begin iterating your product. Start by building an MVP – a high-fidelity prototype that closely simulates how your final product will look and function. It will showcase the core features of your app, and users can test drive these features.
Below is a hi-fi prototype sample for the lo-fi prototype we showed earlier.
Since building an MVP costs less than building a finished product, it’s ideal for collecting feedback from users and stakeholders. With each version of the hi-fi prototype your developers create, you can get more feedback and repeat the process until your app is market-ready.
Stage 6: Launch
After multiple iterations and functionality, aesthetics, and performance optimization, your cloud-based app should be ready to launch. Also called commercialization, launching your app involves making it available to the public. You may need to run ads or other marketing campaigns to bring your newly launched app to users' attention.
Users should be able to access the app to complete tasks and experience value. However, launching your cloud-based app doesn’t mean that development is over. Your development team must monitor how your app operates in the wild. Monitoring usage and other factors will help identify opportunities for improvement so your app can reach its fullest potential and serve users better.
