Understanding serverless computing can be quite confusing. Determining whether or not there is a good development solution for you, it becomes even more complex, because there are so many professionals and opposition to consider.
In this article, we will break the basics of serverless computing for WordPress developers. Then we will discuss some of the factors on which you should decide whether this technique is right for you.
Introduction To Serverless For WordPress Users
It may be difficult to understand serverless computing for the first time, especially since its name is misleading. Although this means that you may be able to develop websites without the server, it is not so.
Instead, the word “serverless” means that the work to establish and maintain the necessary servers to develop your project has been left to the cloud service provider. It gives you more time to commit to actually building your website.
The cloud service provider handles all your back-end processes based on pay-per-use. In meaning, your website is built on a highly scalable architecture. To break all this down a bit further, there are three main features in serverless computing:
- Cloud-based servers that are completely managed by cloud service providers, sometimes called “sellers.” The developer does not have to maintain any server maintenance or worry about the underlying infrastructure of his project.
- The cost that is determined by use instead of pre-defined storage, which you can or can not use to its fullest extent. With serverless computing, you pay only for the performance of your site work, which automatically runs on a scale based on this code.
- An architecture that breaks a website for individual tasks. It is also known as Function as a Service (FaaS), in which the code is executed in response to specific incidents.
In many situations, it provides developers a way to get their projects up and running faster, because they do not have to worry about server maintenance. This reduces cost by increasing scalability, and in some cases, speed. However, technology without a server is not right for every project.
How To Determine If Serverless Computing Is Right For You
If you are trying to decide that serverless computing is a strong option for your next project, there are many ideas to keep in mind. While this method of developing sites and applications can offer many benefits, it depends on the specific properties of your project. Let’s see what this means in more detail.
1. Consider The Size Of Your Project And Its Potential Latency
To start with serverless computing is most successful when used to create static websites or simple applications. To serve users, static files for architecture without a server and a small number of simple tasks are easy to serve.
However, very large dynamic sites do not necessarily charge rentals with very complex tasks. With big projects, the time to run your code will be longer, which can negatively impact the speed of your project and the cost of running it.
A related idea is a frequency with which each function that creates your website will be used. When a function is not called on the server without architecture, its code is not running continuously. If a user calls an unknown request function, then it will need a “cold start”. This will result in latency and can affect your user experience (UX) because the code will take some time to “warm up” again.
2. Decide How Much Time You Can Afford For Maintenance
One of the primary benefits of being serverless is how much time you can save. For example, you do not have to build the infrastructure on which your website will run. You can focus specifically on the code that is specific to your project.
However, even more, attractive time-saving is the fact that you should not worry about server maintenance. Your cloud service provider handles all that for you, saving time not only for development but also for you during the lifetime of your site.
If you have already maintained a server for any other project, then doing a little extra maintenance cannot be a problem for you. When you think of the fact that transferring a project without a server without conventional architecture can be extremely difficult, it is not necessary that you stick with it, knowing that there is a bad idea.
3. Set Your Budget And Compare Costs
The pay-as-you-go financing structure without the server is definitely its appeal. When compared to the traditional way of paying for server space upfront, it seems like the most intelligent option. After all, you will never have to pay for the place that you have not used as you are already paying.
However, this does not mean that serverless computing is not always a low-cost offer. As we mentioned earlier, working over a long time can increase your costs. A large website or a complex application is still going to run a high bill.
In addition, such situations where a large number of requests are made at one go, you can spend more than you can guess. This could include a simple traffic spike or a less pleasant event such as the Denial of Service (DoS) attack. Either way, you will pay for all those requests.
In short, do not just believe that without server the architecture will be less expensive than the more traditional option of prepayment for the management and storage of your own server. Consider the level of your traffic and the complexity of your project, and then compare potential costs before committing to one or the other.
4. Figure Out How Important Is The Scalability For Your Project
Handling the development of a website is a continuation and is not always a simple task. If you are not in the account for a potential increase, then your project may crash and burn. However, you may need to pay for a high-cost server space that is not necessary for you.
Serverless computing raises the question of scalability from your plate and makes it on the responsibility of your provider. The serverless site is highly scalable and applicable immediately to your users’ needs. You no longer have to worry about overloading your traffic, or worrying about other negative side effects of large traffic spikes.
That said, there are many ways to make your project scalable, especially when you are working with WordPress. If there are more reasons to choose a traditional setup, then scalability is not likely to be the only factor that indicates the scale to be serverless.
5. Account For The Lack Of Control Over Your Server
The biggest worry about serverless computing is that there is a lack of control on your server. Although it’s convenient that your cloud service provider handles a lot of tedious details for you, it also limits your access to certain features of your project.
With no access to your server, you are depending on a third party to work properly on your website or application. You will not be able to see your back-end processes, which will make debugging and troubleshooting more difficult than traditional projects.
In addition, there is no way to further the security of your vendor. If you handle user data or other sensitive information, then it can be risky. You will not have any control over whether your project shares server locations with other projects, which can result in data risk. These risks can be reduced, but they are still worth considering.
Serverless computing is not the most straightforward concept. When you hear a lot about its many benefits, there are significant drawbacks to consider. In other words, if the technique without the server is right for your project, then deciding it is not a small task.
To help you get started, here are five factors that you want to think about whether you should think to be serverless computing.
- Consider the size of a project and its potential latency.
- Decide how much time you can give for maintenance.
- Set your budget and compare costs.
- Find important scalability for your project.
- Account for the lack of control over your server.
