The key considerations when switching to serverless
There are many advantages to serverless computing – from increasing cost-efficiency and business agility to lowering upfront cost and ongoing overhead.
As you begin planning the switch to serverless computing, there are a few important things to take into account:
- Serverless functions are accessed only as private APIs, so you’ll need to set up an API gateway.
- If a project has a large number of external dependencies and uses libraries for various functionalities, you’ll need to package these dependencies into the application.
- There’s a hard timeout limit on serverless computing, which could be a concern if you need to execute complex or long-running functions, applications with variable execution times, or services that require data from external sources.
- If you have to run any legacy application, you should evaluate the sustained computing power required to ensure cost-efficiency.
The capabilities of serverless computing are only going to increase as more businesses recognize its benefits and providers continue to improve their offerings.
The Application Of Serverless Computing In Business
While there are still development tasks that serverless is not ideally suited to, there are a variety of use cases forwhich serverless computing is particularly advantageous. Here are some of the most common examples:
- Static content scraping
- Event-triggered computing
- Elastic resizing for live video broadcasting
- IoT data processing
- Shared delivery dispatch systems
- Time-based batch scheduling
