Serverless computing is becoming more and more popular for a variety of reasons. It’s not just the latest trend either; based on new technology, serverless architecture is on the rise, and it’s going to continue to take over. That means you need to know what it’s about and when you might want to take advantage of it.

What Does “Going Serverless” Mean?
Essentially, a serverless setup is one where everything is stored on the cloud, and all computing is done there, as well. This means you don’t have to keep all the servers on your end, yet can continue by using the cloud system.
Traditional vs. Serverless Architecture
Previously, you had to use your own computer or server to compute everything. That meant you were entirely responsible for the servers on-site and had to ensure that you maintained them properly. It can take up quite a bit of your time. Fortunately, there is another option.
Serverless setups are still based on servers but not on your end. The information or application is sent to the cloud and processed, then saved there or sent to the end-user. The fact that you can simply use more space as needed means any small serverless application can be handled in seconds. It’s also great for scalability.
The Benefits of Going Serverless
There are a number of benefits to going serverless. For example, reduced cost is a huge benefit. It costs quite a bit to maintain servers, and you may even end up with a dedicated person to manage the servers if you’re trying to keep up with the load.
When you go serverless, you pay for the orchestration or executions. If you have a short task, it won’t cost much at all, as compared to a server. You’ll pay for the number of executions in each millisecond, using the API to send and receive information.
While there are some downsides to going serverless, the benefits tend to outweigh them. That’s why so many companies are making the switch now. From Google Cloud to Iron.io, there are so many choices in cloud-based computing these days that it can be challenging to decide what to do. Serverless technology has become something that nearly every business needs to do, especially when it comes to real-time computing for things like streaming or managing back-end services.
Why Should You Go Serverless?
Server-centric applications and programming can rapidly become overwhelming, particularly if you’re growing. You’ll need to add more servers and increase the number of jobs you do in your business. However, making those cloud functions can immediately speed up data processing, and none of the debugging is an issue that you need to deal with. The entire ecosystem is out of your control.

Businesses That Have Gone Serverless
You might be surprised at how many companies have gone serverless over the years. Many of them are relatively large, but that doesn’t mean you can’t use it if your business is smaller than, say, Amazon.
A number of web apps that you use for streaming use cloud services to make them more cost-effective. Not only does this afford less downtime, but it also means these web applications are more efficient in providing their services.
Who’s using these cloud-based functions for their back-end services?
Netflix uses AWS Lambda to improve its functionality, while Coca-Cola has been partially serverless since 2016. Nordstrom and Zalora are two other large companies that are serverless. There are definitely some lessons to be learned from these, for either an established business or a startup.
Final Thoughts to Consider
Wondering if you should go serverless? Let’s take a look at what some of the commonalities are between companies that use this method.
1. They need multiple microservices per day.
2. They are trying to automate their workflows.
3. They are often involved in software development or app development.
4. They don’t want to pay for in-house servers.
5. They are rapidly scaling and want to move to auto-scaling.
6. They’ve already dabbled in cloud computing and know the business will do better with shorter time to market timelines
For those interested in going with serverless providers, it’s important to find one that works well for your needs. In order to do that, you must first determine your needs and the serverless functions you will require.
You want a service that has reasonable pricing, works with your operating system, can handle messaging, and is agile enough to smooth out and speed up your workflows.
