Be More Efficient, Go Serverless

Serverless

Ok, let’s make one thing clear: serverless computing doesn’t mean there are no servers involved in the processing of your data. Somewhere, someplace, there is a server running code. The difference is that it is no longer in your office, eliminating your responsibility to maintain, monitor or manage it. In other words, you have outsourced it.

A Brief History:

Many of us remember business computing as it was before the cloud, when everything resided on physical drives, usually on-site. These environments required climate controlled server rooms and dedicated staff.

However, these traditional architectures had a serious shortcoming in that they had fixed resources. This meant that when there was a spike in traffic, the system couldn’t handle it and either broke or needed additional resources applied to it.

Next came the transition to the cloud (or cloud 1.0). This is the type of cloud computing most of us are familiar with. In cloud 1.0, your storage and networking needs are transferred to the cloud, but someone - either a team member or an MSP - still needs the ability to access and monitor it remotely using a virtual machine (a computer program which behaves like a secondary physical computer).

Serverless computing (also known as Functions as a Service, FaaS), cut out the middle-man - instead of needing a VM to manage the functions, the programmer chooses an environment in which code is to be run, uploads the file and the vendor automatically takes over. With serverless computing, there is no need for a dedicated team to manage server operations.

In other words, the IT environment is so automated that it requires no operations to maintain it, as the operations are outsourced.

In a serverless environment, you are only charged for the amount of time and memory required to run your code. This translates to no idle time and no waste. Further, additional cost benefits are realized due to no longer needing a dedicated server room, or the commensurate requirements to keep it functioning optimally.

Some features of serverless computing include:

  • Automatic Scaling: FaaS provides automatic scaling and can easily adapt to changes in scope. Instead of adjusting capacity by purchasing additional server space, your application can be increased merely by adding to the number of resources available.
  • Lower Cost: Serverless can be more cost-effective than a traditional server environment due to the pay-as-you-go nature they have, which allows the user only to use the amount of space they need. In a conventional server environment, there is a lot of potential for the underutilization of resources.
  • Easy Execution: FaaS applications are easy to deploy and update. Simply upload your code and let the platform take over and complete the task.

How does it work?

One of the main differences between FaaS and the traditional server architecture is that FaaS is based on event-driven computing.

The serverless computing provider takes your functions as input, operates the logic, returns your results, then shuts down. You are only billed for the resources used during the execution of those functions. As you can imagine, that makes for significant cost reductions in comparison to a traditional server environment, which can spend a considerable amount of time idle.

So as you can see, serverless computing can allow the SMB the flexibility to grow their business without being held back due to a lack of resources, whether those resources are staff, equipment or time. FaaS is another technology which can allow your business to keep up with the competition.

At KT Connections, we strive to provide businesses the ability to compete with larger operations. We have found the best way to do this is by using technology to level the playing field, as when properly leveraged, technology can have a democratizing effect. Small businesses also have the agility to move and adapt to changing times. KT Connections will provide you with the information and opportunity to grow your business through technology solutions, including cloud-based, serverless computing.
