Why Is Serverless Computing So Important?

Posted on Jul 22, 2021 8:19 pm

Serverless computing is a new form of cloud architecture that has been on the rise in recent years. The idea behind it is to offload all the IT infrastructure needs for an application from the developer and deploy it as a fully managed service without requiring provisioning or management by an administrator.

As a result, serverless computing enables developers to build applications faster because they don’t have to worry about managing their own servers. They also get access to unlimited resources with no upfront costs or commitments.

In this article, we will cover everything you need to know about the principles of serverless computing.

So whenever you’re ready to dive deep into the technical aspects of this topic, keep reading and get your notes handy.

What Is Serverless Computing?

Serverless computing is a new form of cloud architecture that has been on the rise in recent years. The idea behind it is to offload all the IT infrastructure needs for an application from the developer and deploy it as a fully managed service without requiring provisioning or management by an administrator.

Serverless computing enables developers to build applications faster because they don’t have to worry about managing their own servers. They also get access to unlimited resources with no upfront costs or commitments.

As discussed previously, serverless computing works best when you can break your app into smaller parts and allow each piece of code to run independently from one another-like functions that can be executed over different services such as AWS Lambda’s (Amazon Web Services).

These pieces will, in turn, take care of their own needs and not interfere with the overall app.

Serverless computing makes it possible to develop an application without provisioning or managing servers upfront. This means you don’t need to buy a server (or worry about where to put it), pay for hosting services, worry about software updates, etc.–it all happens automatically from within your code. You can also allocate resources on-demand and only pay when needed–there are no commitments required!

The Benefits of Serverless Computing

Serverless computing saves you from the hassles associated with purchasing and maintaining a server for your application’s needs: no need to worry about capacity planning, paying upfront before usage begins–or even worse–paying month after month but only using it occasionally!

This means more time to get important, high-value work done and less time to worry.

Serverless computing enables you to leverage the cloud–specifically, AWS (Amazon Web Services)–to build applications that scale with your needs instead of having a single server handle all requests at once.

This ability sets serverless apart from traditional architectures, where scaling takes longer because it requires manual intervention or additional software licenses.

There are several benefits to using this new technology, including:

  1. Faster deployment times
  2. Reduced management costs
  3. More efficient use of resources because you can scale with your needs instead of having a single server handle all requests at once

This ability sets serverless apart from traditional architectures, where scaling takes longer because it requires manual intervention or additional software licenses.

What’s more, businesses also save on upfront expenditures for servers by leveraging pay-as-you-go services that require no upfront cost but the only bill when there is an activity in the cloud such as storage usage and data processing volumes – so there’s always an incentive to use more.

Additional Benefits

Reduced latency periods as a result of the auto-scaling nature of serverless architecture.

Serverless applications are executed within containers, which means that they have fewer attack points than traditional architectures and only require one set of credentials to access them.

It is cheaper than prebuilt and managed servers, resulting in additional costs like hardware maintenance or software licensing.

Serverless applications can scale quickly without downtime when there are spikes in traffic, unlike traditional web architectures where scaling takes longer to initiate (and comes at an added cost).

And most importantly, you can focus on your business logic instead of managing servers!

Businesses can spend their resources in ways that will drive revenue or create efficiencies rather than focusing on infrastructure management tasks such as security patches, updates for dependencies (e.g., operating systems), network flows across many servers, etc.).

This leads to a smoother customer service experience because it’s not bogged down with IT work.

Why Is Serverless Computing Important?

Serverless computing has grave importance in our modern world, especially for businesses.

It is a cloud computing architecture where provisioning and maintaining servers has been turned over to someone else (i.e., Amazon Web Services, Microsoft Azure).

This means companies can focus on their own business logic without managing/provisioning servers or worrying about serverless costs becoming too expensive (). And most importantly, you can focus on your business logic instead of managing servers!

Serverless Computing Tips

If you consider moving towards serverless computing, we can recommend some tips to ensure your experience is up to par.

Here is a list for first-time users of serverless computing:

Get acquainted with the serverless provider’s pricing model.

Pay close attention to what services are available and how they’re billed so you can plan for any unexpected costs.

Consider whether a particular service is worth it or not based on your needs, as there may be other options that would work just fine without costing you more money each month.

Keep abreast of new features that might make serverless computing fit in better with your organization’s goals.

AWS Web Services (AWS) providers have been offering cloud hosting solutions since 2006, but AWS Lambda was introduced only two years ago. It offers an alternative to traditional web hosting platforms, such as dedicated servers and VPSs.

Stacks of Serverless

The serverless world has been evolving rapidly, and it is becoming increasingly difficult to keep track of all the available stacks. It’s not always easy for developers to know which stack they should use because each one offers different programming languages, frameworks, or triggers.

If you’re looking for a framework with NodeJS support, then Lambda Functions would be your best bet, but if Python is more what you need, then try out Apex on Google Cloud Platform to stay up-to-date with both language trends while still getting access to powerful tools like BigQuery and TensorFlow from MLflow.

AWS Lambda, Google Cloud Functions, and Azure functions all have their own specific triggers. With AWS, there are a few more generic ones like Amazon Simple Email Service (or SES) or CodeCommit – both of which can only be triggered on the AWS platform.

On Google Cloud, you may want to use HTTP requests if they’re available in your package, but for other packages such as Twilio, we found that it’s not currently possible to trigger them with an HTTP request; instead, developers must rely on hosted webhooks from external services or setup up API calls through our cloud tooling.

And finally, Microsoft Azure has no natively supported triggering mechanism, so that users will need some additional service outside of these platforms.

Frameworks of Serverless

The framework you use will dictate the structure of your application. Amazon has created its own native, open-sourced Serverless Application Model (SAM). Still, there are other frameworks too that can be used to create cross-platform and also open source applications.

With Serverless, developers get the same experience on each platform. AWS Lambda is just one of many supported platforms that include Azure Functions and Google Cloud Functions, to name a few.

In addition, apex helps bring some languages not available in certain providers into the mix, like IBM OpenWhisk, such as supporting more than 40 other popular programming languages, including Java 8 and PHP 5+.

With so much focus being put onto cloud computing these days, it’s hard not to find at least two or three different solutions out there claiming they’re able to meet all your needs when you really only need something simple yet reliable such as an API server capable of making HTTP requests from within Amazon Web Services (AWS).

Databases of Serverless

Serverless code is a newer programming paradigm that allows developers to create scalable applications without knowing servers or even being required to provision them.

However, because serverless code has no persistent state and runs entirely in RAM, the developer needs to know how to store data across instantiations so their app will work properly.

All major cloud vendors provide triggers with databases you can interact with through your functions which solves this problem elegantly by storing all necessary information on-premise instead of requiring an external database like AWS S3, DynamoDB, etc.

Data storage is a complicated and expensive process. But serverless databases, also known as post-relational databases, make this task much easier by automating data management without requiring any provisioning or maintenance from the user.

In addition, the lack of servers means there are fewer moving parts for things to break down on you in addition to financial savings over time; all that’s required is an internet connection!

Serverless Unhinged

Now that you understand the principles of serverless computing, you are well on your way to make use of it. Ensure that you cover all aspects of computing because you don’t want to make mistakes on the get-go.
