10 amazing benefits of serverless technology


If you’ve heard of the term “serverless architecture” but you have no idea what it means, don’t feel bad. This buzzword (buzz-phrase?) has been on the rise for the past few years, and it doesn’t look like it’s going to stop. More and more cloud companies are trying to promote serverless architectures for businesses.

But why?

There are plenty of benefits to using a serverless architecture for your business. If you’re ready to take the plunge, dive into why a serverless architecture could work for you.

So What is Serverless Architecture?

“Serverless” technology has two different definitive camps, each that describes their application architecture.

The first is Back-End as a Service or BaaS. This applies to any application that features most of their backend on the cloud. This is usually monitored or maintained by a third-party. You’ll usually find applications that are front-end heavy to exist on serverless architectures. This can include mobile apps or web applications that feature a rich and complex UI.

On the other end of the stick, there is Function as a Service or FaaS. FaaS features an application that runs parts of their code through event triggers. The serverless architecture allows apps to evoke functions on demand. This is useful as it provides flexibility for server-side applications.

Now that we’ve broken down the use cases of serverless architecture, let’s dive deeper. Here are 9 benefits to using a serverless architecture for your project.

1. Easy To Deploy

A serverless approach for your application could be perfect. If you need to spin up an app fast, serverless might be your solution. Instead of weeks and months to deploy an app, you can do it within hours and days. The reason behind this is that you don’t have to concern yourself with infrastructure. You can focus on the code and release it immediately. Scalability is automatic and you don’t have to worry about any provisioning needs.

2. Low Cost

Going serverless is a great way of cutting costs. That’s because you’re outsourcing the responsibilities of managing servers, databases, and some logic. Besides the actual cost, serverless takes less computing power and human resources. There’s no reason why you need to build a server from the ground-up on your own. Since serverless takes care of the infrastructure, you can focus on the server-side code that matters. There are situations where the cost isn’t that much cheaper, but it’ll depend on your use case.

3. More Time For UX

If your application caters to customers, remember this: customers don’t care about infrastructure. They don’t get to see all the code that you’ve written for your back-end. The only thing they’ll notice is the front-end code. The user interface and experience is more important to them. So why not focus on allocating resources to elements that keep customers happy?

4. Better Scalability

If you’re aiming to be the next Google, you need to consider whether your server can handle a load like that. Going with a serverless architecture allows you to roll with the punches. If your app succeeds and grows, it’ll be easy to stage changes that accommodate the growth. If not, then no harm done! There’s no need to provision infrastructure without knowing whether it’s needed for sure. That’s a huge benefit.

5. Improved Latency

Serverless architectures usually have access points on a global scale. That means that it’ll be easier to handle users from every corner of the world. This way, you can scale without affecting the performance of your application. As an example, imagine that you host a server the traditional way on the West Coast. If a user from the East Coast uses your app, they’d have to send a request the entire distance and back. For a serverless architecture, it would only go as far as the closest serverless node, which might be on the West Coast! The only potential downside is cold starts, which is the ramp-up time for an app to build and to be placed in a container.

6. “Greener” Hosting & Computing

Companies that host data centers or their own servers need to run their servers at all times. Think about all the huge data centers and the physical resources needed to build these centers. Think about the energy needed to keep them running. The good thing about serverless architecture is that you can buy servers on demand when you need it. This can reduce the resources needed to keep various companies online.

7. Improved Flexibility

It’s easier to begin implementation of an app with serverless than it is with traditional methods. Because of that, going serverless means you can innovate faster as well. When you can see tangible results return immediately, you can move on to the next project. You can start building your next feature or your next microservice. Serverless architecture provides this benefit when you’re not bound by constraints. It’s also easier to pivot in situations where you need to restructure.

8. Happier Customers

This will depend on the company in question. A serverless architecture can potentially lead to happier customers. A company that can draw up new servers and ship features faster means that customers can access these new features. Nobody wants to wait an entire year for small fixes. Through serverless, you don’t have to worry about infrastructure. You can release logic and features quickly that will improve the user experience.

9. More Efficient

A serverless architecture means that you pay per request. If you had a traditional server, you’d keep it running at all times. With a serverless architecture, you’re only charged when the server’s used. That means there is less waste generated as well. It’s also more efficient because you no longer have to worry about scaling. Infrastructure, setup, capacity planning, and DevOps are no longer your concern.

10. It’s freaking awesome

Look, I’m going to level with you. I could only think of 9 awesome benefits of serverless technology but I just couldn’t let this article be: “9 benefits of serverless”, it didn’t sound right to me. With that being said, I’m going to say that the 10th benefit of serverless is its awesomeness and the awesomeness of the people in the serverless community.

Is serverless the way to go?

Going with a request-driven, serverless architecture could be the right move. It could also be a poor choice for your company, depending on what sort of app you’re building. Be sure to dive into serverless knowing what components your application will have and how large it’ll be. If serverless seems like a great fit, there’s no reason why you shouldn’t try it. Just don’t forget to monitor your serverless environment. Dashbird offers easy and fast monitoring solutions to make serverless apps reliable at any scale, all in one easy to understand dashboard.
