Serverless Computing

Serverless is a term that has been around for some time, but many companies are dipping their toes in to see if it is for them. Serverless computing is a new way to build and deploy applications – you don’t plan ahead how much storage your application needs or lines of code it will need, etc., as there are no servers to manage.

It allows developers to run code without provisioning or managing any servers. These services are designed to provide scalability and high availability, and they can be run in response to events or invoked directly by other cloud computing services.

With serverless services, developers can build applications faster and cheaper, without having to worry about server management.

One of the biggest benefits of serverless compute is that it can help you save money on infrastructure costs. With traditional server-based architectures, you have to pay for the servers even when they’re idle.

With serverless compute, you only pay for the resources your code actually consumes. This can result in considerable savings, particularly for apps with sporadic or infrequent usage

Why is this called ‘serverless’?

The term “serverless” can be a bit misleading. In this context, it doesn’t mean that there are no servers involved. Rather, it means that the developer doesn’t have to worry about which servers their code is running on or how those servers are being managed.

With serverless compute, all of that is taken care of by the service provider. The developer just needs to write their code and deploy it. This can be a major advantage, as it frees up developers to focus on building features and functionality, rather than worrying about infrastructure.

It’s also worth noting that serverless compute can be a very cost-effective way to run code, as you only pay for the resources you use (often by the millisecond). There’s no need to worry about underutilized servers or paying for idle time.

How is serverless compute different than other web hosting models?

Like I said in serverless compute, you don’t have to worry about provisioning or managing servers. Your code is simply deployed to a cloud provider and executed on demand. This can provide significant cost savings and simplify your overall architecture.

Traditional web hosting models require you to provision and manage servers. This can be costly and complex. With serverless compute, you don’t have to worry about this. Your code is simply deployed to a cloud provider and executed on demand.

Serverless compute can provide significant cost savings and simplify your overall architecture. It’s definitely worth considering for your next web project.

What can you do with serverless compute on AWS, what are some examples of usage?

With serverless compute on Amazon Web Services (AWS), you can run code without provisioning or managing servers. AWS Lambda, one of the services that offers serverless compute, runs your code only when needed and scales automatically to match the rate of incoming requests.

Some examples of usage for serverless compute include powering real-time applications such as chatbots and gaming applications, running event-driven workloads such as processing images or videos, and building IoT backends.

Why would businesses want to use serverless computing like AWS Lambda?.

Businesses seeking to tap into the power of serverless computing can significantly decrease the cost and effort of building, operating, and scaling applications by eliminating need for managing servers and backing them up.

In addition to these benefits, new serverless compute services can enable developers to focus on problem solving rather than back-end infrastructure design. The flexibility of serverless computing is enabling companies around the world to build highly scalable, high-availability systems at a price point unheard of just a few years ago.
