Technology today is advancing rapidly. In the past, web or application developers had to manage servers themselves—choosing the server hardware, managing the operating system, ensuring security, and scaling the servers as the number of users increased. However, with technological advancements and the emergence of Serverless Computing, these responsibilities are now “hidden” behind the scenes by cloud service providers such as AWS Lambda, Google Cloud Functions, or Azure Functions. All you need to do is simply “write functions” for the system to operate as required.
What is Serverless Computing?
The term “serverless” does not mean “no server,” even if the name suggests so. In reality, servers still exist and are managed by cloud service providers (Cloud Service Providers – CSPs). The term “serverless” refers to the developer experience where they do not need to see, manage, or interact with those servers directly. Cloud providers take care of everything else—provisioning the necessary cloud infrastructure to run code, scaling the infrastructure up or down according to demand, and managing routine maintenance tasks such as OS updates, security patching, capacity planning, system monitoring, and more.
Developers can fully focus on writing front-end code and business logic. All they need to do is write their application code and deploy it in containers managed by the CSP. Additionally, they don’t have to pay for unused resources. In a serverless system, the cloud provider only allocates computing resources when the code is running and shuts them down when the execution ends. Charges begin when the code starts running and stop when it finishes, with pricing based on execution time and resource usage.
Benefits of Using Serverless Computing in Business Development
Implementing Serverless Computing in business development offers significant benefits, which can be categorized as follows:
- Reduced Operational Costs
– Business owners only incur costs when the service is actually used (pay-per-use).
– Saves on expenses related to managing underutilized servers or systems.
- 2. Increased Development Agility
– Developers can deploy code quickly without waiting for system setup.
– Well-suited for Agile and DevOps workflows.
- Automatic Scalability
- The system can scale up or down automatically based on real-time user demand without infrastructure modifications.
- 4. Faster Time-to-Market
– Enables businesses to launch new products or features more quickly.
- Greater Focus on Core Business
– Development teams don’t have to manage backend infrastructure, freeing up time and resources to develop solutions that better meet customer and market needs.
Examples of Businesses Suitable for Serverless Computing
- Startups Looking to Save Costs
– No need to rent servers continuously.
– Ideal for testing ideas or building MVPs.
- E-commerce with Unpredictable Traffic
– Serverless can automatically scale usage up or down.
– Helps handle traffic spikes during flash sales effectively.
- Businesses Focused on Automation, such as:
– Line notification systems.
– Email systems triggered by orders.
– File or image processing after uploads.
- Organizations Working with Big Data or AI
– Suitable for lightweight processing divided into many smaller tasks (e.g., file conversion, targeted data analysis).
Based on the above information, if you’re a business owner looking to rapidly develop technology or applications, save budget, scale based on real usage, and avoid infrastructure complexity, Serverless Computing is a cost-effective solution for 2025.
