Ever since AWS Lambda was introduced in 2014, several businesses have been looking for serverless hosting providers to help them run their applications.
It’s true that serverless platforms are getting popular and for a good reason! They’ve offered developers a convenient way to run their web applications without worrying about provisioning and managing servers.
If you’re unfamiliar with serverless computing, how it works, or how it could benefit your business, we’re here to help you out. In this article, we’ll give you a crash course on serverless hosting and some of the most popular providers in the market.
How Does a Serverless Architecture Work?
To fully understand what and how serverless architecture works, let’s briefly define a server. In the traditional web hosting world, a server is a physical or virtual machine that’s responsible for running your applications and storing your data.
But with serverless architecture, you don’t have to worry about these things. That’s because serverless platforms allow you to run your code without having to provision or manage any physical servers.
So, how is this possible? Well, serverless platforms are built on top of existing infrastructure, and they use what’s called a “function as a service” or FaaS model.
With this model, you can write and deploy your code without having to worry about server management. The platform will automatically provision and scale the servers required to run your code.
However, the term ‘serverless’ can be a bit misleading because there are still servers that power these backend services. It’s just that all of the server administration and management are handled by a cloud provider.
The Role of Cloud Providers in Serverless Computing
Serverless services are usually offered by cloud providers, and they play a vital role in making sure that these services are up and running.
As mentioned, serverless computing is not entirely ‘serverless’ because there are still servers that power these backend services. But instead of managing these servers yourself, the cloud provider will take care of them for you.
What are the responsibilities of a serverless provider? A serverless provider is responsible for the following:
- Providing a FaaS platform that allows you to deploy and run your code without worrying about server administration.
- Managing and scaling the servers required to run your code.
- Handling all of the security patches and updates for the servers.
In other words, a serverless provider will take care of all the heavy lifting when it comes to running your application code.
A thing to remember here is that not every serverless vendor is the same. Some providers may offer container-based solutions, while others may only offer back-end-as-a-service or BaaS.
It’s important to do your research and choose a provider that offers the services that you need. For example, if you’re building mobile apps at scale, find a company providing backend services.
Common features offered by serverless vendors:
- Automatic scaling
- No need to provision or manage servers
- Pay-as-you-go pricing model
- Supports multiple programming languages
- Cloud storage platform for your content (including videos, music, and photos)
- Mobile connectivity
- User-based security
- Simplified testing and troubleshooting process
- App testing (physical or virtual)
Now that we’ve covered the basics of serverless architecture, let’s learn the advantages and risks associated with this hosting solution!
The 5 Benefits of Using Serverless Functions
Partnering with serverless providers can offer you several advantages, such as:
1. Reduced Costs
One of the biggest advantages of going serverless is that it follows a ‘pay-as-you-go’ pricing model. This means that you only have to pay for the resources that you use, and there are no upfront costs.
Unlike traditional web hosting, you’re not paying for idle capacity. This can help you save a lot of money, especially if your applications don’t have consistent traffic.
2. Increased Efficiency
Another benefit of using a serverless model is that it can help increase your team’s efficiency. Since you don’t have to worry about provisioning, managing, or scaling servers, you can focus on building and running your applications.
This can free up a lot of time for your IT team, and they can use that time to work on other things that can help improve your business.
3. Enhanced Scalability
Serverless platforms are also highly scalable, and they can automatically scale your applications up or down based on traffic demand. This means that you don’t have to worry about manually scaling your servers, and you can focus on running your business.
4. Improved Security
When it comes to security, serverless platforms can offer you several advantages. First of all, you don’t have to worry about patching your servers since that’s all handled by the cloud provider.
In addition, most providers offer a wide range of security features, such as firewalls, intrusion detection, and more. This can help you secure your applications and data without having to worry about the underlying infrastructure.
5. Faster Time to Market
If you’re on a time crunch and need to get your application to market quickly, then a serverless platform can help you out. That’s because you don’t have to spend time provisioning or managing servers. You can focus on building and running your application so that you can get it to market as soon as possible.
3 Risks You Want to Avoid When Looking for a Cloud Provider
Of course, no solution is perfect, and there are some risks that you need to be aware of when looking for a cloud provider. Here are some of the risks that you want to avoid:
1. Vendor Lock-In
One of the biggest risks of using a serverless platform is vendor lock-in. This means that you could be tied to a specific provider and find it difficult to switch to another one in the future.
Make sure to do your research and choose a provider that offers an easy way to migrate your applications to another platform.
2. Lack of Control
Another risk of using a serverless platform is that you could lose some control over your applications. This is because the cloud provider will be responsible for managing the infrastructure and servers.
Make sure to choose a provider with a good degree of control and visibility over your applications.
3. Complicated Testing and Debugging
When it comes to testing and debugging your applications, a serverless platform can make things more complicated. That’s because you’ll need to test and debug your code in the context of the cloud provider’s infrastructure.
Make sure to choose a provider that offers good testing and debugging tools.
In a nutshell, these are some of the advantages and risks that you need to be aware of when getting serverless solutions. Choose a provider that offers the right mix of features and services that meets your needs.
