In 2023, the expectations on software developers to build high-performance websites and applications are tremendous. After the pandemic, users have become more dependent on apps and services, which means they have no tolerance for poor performance, even when those apps are experiencing record traffic numbers.
At the same time, a series of high-profile breaches have made cyber security and application maintenance more important than ever. It’s no wonder that developers cite security, keeping up with innovation and meeting customer expectations as some of their biggest challenges.
By capitalizing on the benefits of serverless computing, some developers may be able to reduce their stress without negatively impacting the quality of the applications they provide. With the right strategy, serverless computing can help reduce costs, improve developer efficiency, increase security and deliver better results.
First, let’s take a look at some of the benefits of serverless computing:
1. Streamline logistics and reduce latency
The term “serverless” is a bit of a misnomer. Servers are included, but a third-party provider maintains them instead of you, making the infrastructure “serverless” from that point of view. The most immediate and obvious advantage is that you won’t need to maintain the low-level infrastructure or operating system your application will run on. Finding a provider you trust will allow you to focus solely on optimizing your code.
There is now increasing overlap between edge computing infrastructure and serverless providers. For these providers, the infrastructure is pushed to the edge of the network, as close to users as possible. This distributed footprint can reduce application latency substantially, and the serverless infrastructure means you don’t need to worry about skill gaps or your employees not being proficient with edge deployments.
2. Quickly scale with demand
With serverless computing, you only need to pay for the server functionality you actually use, allowing for scaling up or down to meet demand. This is in contrast to other options (such as container-based architectures), which require computing resources to be paid for upfront and may not fit your actual needs. As a result, this scaling can help eliminate the additional costs and risks of not provisioning enough infrastructure.
3. Integrate New Features Easily
Another advantage of serverless computing is that serverless platforms usually come with pre-built integration with third-party applications. It allows developers to quickly and cheaply build application functionality with existing modules and features that can increase time to market while improving performance and security.
Serverless Computing Challenges
Of course, in addition to examining the benefits of serverless computing, it is necessary to consider some potential concerns.
One well-known risk is the possibility of vendor lock-in. Any app you develop may be bound by vendor-exclusive standards. This can make it difficult to switch to other vendors later. Another common concern is related to latency. Because serverless infrastructure needs to be activated each time it is used, it has historically introduced “cold start” delays that can cause websites to take longer to load. And perhaps most fundamentally, many companies are hesitant to hand over control of their infrastructure to a third party.
Because these risks are well documented, providers are working to overcome them to make serverless computing as attractive as possible to potential customers. Some providers have adopted open standards such as WebAssembly and Web API to improve the ease of onboarding to serverless platforms and facilitate departure from the platform if company strategy changes. Additionally, some now offer technology that removes the “cold start” delay, functionally eliminating latency.
Who Benefits Most from Serverless Computing?
Companies ranging from Netflix to Coca-Cola and Nordstrom have found uses for serverless computing. If any of the following use cases fit your needs, you might consider joining these companies as a relatively early adopter of serverless.
1. Inconsistent, Simple, or Short-Term Compute Requirements: If you deal with erratic workloads that are challenging to anticipate in advance, or simple and short-running applications, serverless computing may allow you to pay only for the compute you need and improve cost-efficiency. can do.
2. Ultra-low-latency applications, If your use case requires or needs to benefit from low latency (i.e., related to high-performance applications or 5G) then combining serverless computing with edge computing can be very helpful. Automatic scaling closer to end users can help meet the dynamic and urgent needs of ultra-low-latency applications (such as self-driving cars).
3. Applications that increase functionality or rapidly improve security: If your use case requires you to extend the functionality of an already existing application quickly and at low cost, or add new security features quickly, you can use third-party serverless platforms to add new capabilities. May be able to rely on integration. Quickly, like a web application firewall, a new authentication and authorization service, or a simple A/B testing feature.
In an era of rapid innovation and rising user expectations, the logistical and financial benefits of serverless technology may be enough to make the enormous challenge bearable. Take the time to choose a serverless provider that enables you to run on modern compute architectures, such as edge computing, and that fits your needs. And make decisions while looking for the mid- and long-term benefits, so you can focus your attention solely on the code that matters most without sacrificing performance or security.
