Word of the Day: serverless computing

Word of the Day Daily updates on the latest technology terms |May 21, 2018

serverless computing Serverless computing is an event-driven application design and deployment paradigm in which computing resources are provided as scalable cloud services. In traditional application deployments, the server's computing resources represent fixed and recurring costs, regardless of the amount of computing work that is actually being performed by the server. In a serverless computing deployment, the cloud customer only pays for service usage; there is never any cost associated with idle, down-time. Serverless computing does not eliminate servers, but instead seeks to emphasize the idea that computing resource considerations can be moved into the background during the design process. The term is often associated with the NoOps movement and the concept may also be referred to as "function as a service (Faas)" or "runtime as a service (RaaS)." One example of public cloud serverless computing is the AWS Lambda service. Developers can drop in code, create backend applications, create event handling routines and process data - all without worrying about servers, virtual machines (VMs), or the underlying compute resources needed to sustain an enormous volume of events because the actual hardware and infrastructure involved are all maintained by the provider. AWS Lambda can also interact with many other Amazon services, allowing developers to quickly create and manage complex enterprise-class applications with almost no consideration of the underlying servers. Quote of the Day "If executed correctly, a serverless architecture can save development teams time when pushing out new features and can scale nearly infinitely." - Chris Moyer   Trending Terms event-driven architecture NoOps AWS Lambda Microsoft Azure Functions enterprise application integration cloud services event handling     Learning Center IT pros test out fresh crop of serverless monitoring tools Serverless monitoring tools have quickly added sophisticated features, but a view of the serverless infrastructure that includes distributed tracing and third-party dependencies awaits further development. The pros and cons of serverless architecture Serverless architecture can save development teams time when pushing out new features and scaling, but it does not come without trade-offs. Serverless infrastructure calls for updated IT ops expertise Enterprises will need IT ops pros with systems engineering expertise to bring serverless infrastructure for complex apps to maturity. When is serverless technology best for app modernization? Red Hat serverless technology expert Rich Sharples analyzes why some businesses are exploring serverless use cases for application modernization. Know when to implement serverless vs. containers IT pros must be equipped to guide application deployments onto serverless vs. containers, or vice versa, for off-the-shelf apps, in-house projects and microservices. Writing for Business Serverless computing can significantly bring down costs since you're not paying for servers 24/7, _________ of whether they are actively serving requests.
