Serverless computing is a new way of building and running applications. It promises to reduce cost, improve speed and simplify maintenance, making it easier for developers to build better apps faster.
Reduce cost and increase speed
There are a lot of reasons to choose serverless architecture over traditional, but the main ones are:
- Cost savings—Serverless architectures can reduce your costs by up to 90%. This is due to the fact that you only pay for what you use. There’s no need for expensive hardware or infrastructure maintenance because everything runs on AWS.
- Speed of development—Serverless architectures enable developers to focus on code rather than on infrastructure management and resource provisioning. Developers can quickly build, test and deploy new applications without worrying about how much it will cost or how long it will take for them to be ready for production usage.
- Speed of deployment—The speed at which you can deploy an app is one of the most attractive benefits of going serverless. Nowadays most cloud providers offer zero-downtime deployments — meaning that as soon as one version of your application goes live, another one immediately replaces it with no service interruption whatsoever (unless explicitly configured). This enables teams working in a continuous delivery model where code gets deployed multiple times per day without having any negative impact on business productivity
The best part is that, once you have your app built, you can deploy it to production in minutes. And when you want to test out new features or change directions, that’s just as fast. You don’t have to wait for a build or publish step, or anything else that might hold up your progress. This means that you can iterate quickly and focus on building the best product possible—not on waiting around for build time or deployment windows.
Remove maintenance hassle
Traditional servers are complex pieces of technology, and keeping them running requires a lot of maintenance. You need to monitor your server for resource usage or performance issues, and make sure everything is running smoothly. Serverless removes this hassle by taking care of that for you—you don’t need to worry about how many resources your application is using, or whether it’s optimized for speed. The platform does all that work instead!
The benefits don’t stop there: serverless also makes development easier by allowing developers to focus on building their applications instead of managing infrastructure.
Build smarter apps
In an increasingly complex world, developers need to think smarter. With serverless, you can focus on the things that matter most: your application’s architecture and business logic.
Serverless applications are simpler because they are decoupled from servers and infrastructure. You can build your app with a single function or by stringing together multiple functions as needed for different use cases—and then deploy all of it at once with no additional work required to scale up or manage any part of the stack.
Serverless apps are more scalable because you pay only for what you use in real time—and scale up quickly if needed with only a few simple clicks. In addition, serverless apps typically require fewer resources than traditional web architectures so there’s less chance of hitting capacity limits early in development which frees developers up to focus on creating new features instead of maintaining old ones..
Serverless apps are more secure thanks to automatic encryption at rest and in transit across AWS Lambda layers without requiring any additional code changes beyond uploading a function package (which is itself encrypted). This ensures sensitive data stays safe even if someone gains access through other means such as social engineering or brute force attacks against accounts containing credentials stored outside Amazon Web Services’ security perimeter (AWS CloudTrail logs confirm that no unauthorized access attempts have been attempted since last month).
Serverless is the future of cloud computing.
Serverless is a new paradigm for cloud computing that allows you to build and run applications without thinking about servers. That’s right: no more server hardware or virtual machines, no more worrying about scaling up and down, no more fiddling with load balancers. Serverless takes care of all that mundane stuff for you. No need to worry about installing operating systems or monitoring your app’s performance—the cloud provider does it all automatically.
Serverless reduces infrastructure costs by allowing developers to focus solely on their code rather than spending time setting up complex infrastructure configurations (like managing servers). It makes it possible for small companies without large IT budgets to compete with larger ones because they can spend their money where it counts: on improving their product instead of buying another server farm!
Of course there are other benefits too: serverless helps make applications faster by automating time-consuming tasks like provisioning EC2 instances; it also makes them easier to maintain since there are fewer moving parts in the system; finally, it allows developers who specialize in frontend work do so without having much knowledge about backends!
We’ve covered a lot of ground here, from the basics of serverless to real-world use cases and examples. We hope that you now have a better understanding of what serverless is and how it can be used in your own projects—and if you’re still unsure about whether or not it’s right for you, we think this guide will help you figure out what kind of applications would benefit from going serverless.
