Serverless Architectures


BY Bogdan Kulbida / ON Dec 22, 2018

Many companies have adopted cloud services to run applications in an effort to reduce or remove server management overhead. You may have already heard of form of cloud computing called Functions-as-a-service, or (FaaS), which provides clients a way to access serverless computing resources without having to build all the infrastructure normally required to develop and run software. Analyst estimates suggest that around 85 percent of servers are underutilized, implying a great deal of wasted computing capacity. Opting to utilize cloud computing instead of paying for the hardware and infrastructure required for server maintenance could save you a good portion of your budget. We would like to discuss with you, the benefits of FaaS, specifically AWS Lambda. AWS Lambda is a serverless computing platform that allows for the development and operating of software without requiring a client to purchase or maintain server infrastructure.

Every manager is aware of the toll that utilization takes on their hardware, and the cost of maintaining or replacing hardware that sees heavy use. In the case of FaaS, these concerns are removed from your plate, and there is the added benefit of no longer needing to constantly monitor and patch your servers. In fact, AWS rebuilds their Lambda underlying servers a few times per day - according to AWS whitepaper, including patching and any necessary software upgrades. Security is also managed by the cloud personnel, who not only monitor, upgrade, and patch the servers, but provide proper security of your Function environment. Also included with the AWS Lambda service is complete encryption of your environment variables. Further, we recommend using AWS Serverless Application Model (SAM) to allow you to quickly and easily create, test, and deploy your functions. AWS SAM will aid you in efficiently implementing your functions in the AWS Lambda environment.

When your developers trigger a functions execution, only then are you utilizing the FaaS environment, this is a clear advantage when compared to the overhead and management of servers that may experience long periods of idling, or waste. You are only paying for the milliseconds that your function is running. The servers that you would be utilizing through your FaaS partnership would also be tuned for maximum performance and throughput, which would allow your functions to execute efficiently, without requiring you to plan and reserve computing resources. There is also no requirement for scaling-out or scaling-in as scaling does not apply to FaaS.

While not every service can be implemented in a FaaS paradigm, we at Konstankino carefully analyze client infrastructures and requirements before abstracting any component of the job to serverless FaaS. Please consider reaching out to us, should you require help with your server architecture and would like to migrate to serverless computing. We would be happy to help.
