Application development using cloud technology has long been a standard, both for large companies and for various startups.
The needs of end users have become very specific, and to satisfy them, applications are needed that require significant computing power, stability and a high level of security of sensitive data. In order to ensure the smooth use of applications by users on their computers, companies use cloud infrastructure, thereby overcoming the limitations of user devices and enabling the smooth use of complex applications.
Cloud app development is the process of creating applications that use cloud infrastructure to store data, process information, and perform logical tasks. This approach allows applications to run on any computer or mobile device, regardless of their technical specifications, as long as there is internet access.
Developers often use cloud services such as IaaS, PaaS, and SaaS because they provide the infrastructure and tools that facilitate the process of developing and testing applications.
Cloud solutions allow for significant savings because they eliminate the need to invest in servers and their maintenance. Instead of a company purchasing expensive infrastructure and hiring a team of people to take care of the servers, the cloud provider takes care of all this. You only pay for the resources you use, without unnecessary fixed costs. This way of working results in reduced costs, simpler resource management, and more time to focus on what really matters, application development and user experience creation. This is especially important for startups because the low initial costs of developing an MVP can play a key role in its success in the future.
Instead of complicated on-premises server setup and infrastructure requirements, applications can now be quickly deployed and made available to users. Without the need for complex technical setup, development teams can focus on functionality and user experience, while hosting, scaling, and security are left to cloud platforms. The result? Faster delivery, lower costs, and easier application maintenance, meaning ideas can go from concept to reality in record time.
Many user data are stored on different servers. This data can sometimes be very confidential, such as users’ personal data, data from their bank cards, etc. If this data reaches people with bad intentions, it can harm both users and application owners. That is why it is very important to have a high level of data security.
Fortunately, cloud platforms ensure the security of user information using various methods, the most common of which are: data encryption, access control and multi-factor authentication. Also, regular updates to security protocols reduce the risk of unauthorized access and cyber threats.
There are various reasons why data loss can occur. This usually happens when the server’s power is cut off, the server is physically damaged, and in some cases, if the security is not at a high level, due to hacker attacks.
It would be best if such situations did not occur. However, if they do, most cloud platforms come with built-in backup and disaster recovery mechanisms. These mechanisms allow for a quick return to operation of the application with minimal losses, and minimal dissatisfaction of the application users.
Use of cloud technology and application development provides benefits for developers, i.e. in the cloud it is possible to use the same code without sending files or manually adjusting the system.
Everyone can simultaneously access the project and share resources. Testing and deployment are faster thanks to automated CI/CD tools, which reduces the time from development to production and eliminates problems such as the application running on one device and not another. The environment remains consistent no matter where the app is running.
Instead of spending more time on setting up servers and infrastructure, developers can use ready-made cloud services and focus on developing new functionalities, which significantly speeds up the application development process.

Application architecture planning can determine the speed of development, scalability and other elements that are of great importance. Therefore, we need to consider the long-term goals of the application and its development plans. Based on this, the choice of cloud application architecture is made. The wrong choice of architecture applications can come Monolithic architecture: A large application with many connected functionalities, which is relatively independent of other systems, represents a prime monolithic architecture.
This traditional application development model is simple to implement compared to alternatives, but it lacks flexibility. As the application grows, maintenance and scaling can be challenging, because every change requires updating the entire system.
Microservice architecture: Microservice architecture implies the division of applications into smaller, mutually independent components that communicate via REST, APIs or other methods, and are organized according to the logic they perform.
This approach enables easier maintenance, quick upgrades and independent development of individual components. Although it brings greater flexibility and scalability, microservice architecture can be complex to implement, as it requires precisely defined communication protocols and distributed system management.
Serverless architecture: This architecture allows developers to use the infrastructure of applications, such as databases or storage, because the resources are provided by cloud providers such as AWS, Azure or Google cloud.
Serverless access reduces operational costs and enables fast delivery of functionality, but it can lead to dependence on the cloud provider (vendor lock-in) and increased costs at high volumes of use.
Hybrid architecture: Combines public and private cloud, allowing applications to take advantage of both models. Applications that use this architecture usually store sensitive data on private servers for security and regulatory requirements, while other resources are stored in the Cloud environment for better availability and scalability.
This approach allows greater control over the data, but it can increase the complexity of the infrastructure management.
The choice of the right technologies for the development of applications on the cloud is one of the keys to using these technologies as mentioned earlier. The more popular microservice architecture, which allows the application to be broken into smaller parts, gives developers the opportunity to use technologies for each part of the application that will give the best results when we talk about the performance of the application.
Programming languages like Python, JavaScript (Node.js), Java, Go (Golana) and C# (.NET) are used for cloud application development. React and Angular are the most commonly used frameworks. While PostgreSQL, MySQL and MongoDB are used for databases.
When we talk about cloud application development, we don’t mention containerization. Containerization is the process of packaging code, with all necessary configurations and libraries implemented in containers. This allows you to run the application on different platforms, without the need for additional infrastructure adjustments or the platform on which the application runs. Two tools that are most often used in this process are Docker and Kubernetes. While Docker provides a stable environment, Kubernetes, as a container orchestration system, automates their management, scaling and traffic balancing. The combination of these two tools enables a stable, efficient and scalable work application in a cloud environment, with high flexibility and availability.
Developing applications with the help of cloud technologies brings numerous advantages, especially for startups, where smaller initial investments can be the key to success. Greater scalability and faster development further contribute to the efficiency of the project.
However, getting the architecture right is key and poorly implemented solutions can negate all the benefits of the cloud. That is why it is important to consult experts who will know how to avoid obvious – and not so obvious – challenges and mistakes in the design of the environment, so that the application is effective, safe and profitable.
