The term Serverless was popularized after 2015 after Amazon launched Amazon Lambda. After that cloud vendors like Google & Microsoft started embracing it. It brought a more simplified method of application development.
Businesses are finding it as a solution to free themselves from system administration. This is providing both technological advancement and reducing infrastructure costs. Companies got more opportunities to scale the server up and down according to user requests. It’s possible to build, test & deploy the code without any host solutions. This has made the deployment (management) of codes easier.
Why does Serverless hold Great Promises for Enterprises?
It unburdens the businesses from infrastructure management and helps to focus them more on efficient work rather than engaging a team to manage those servers. Besides, this has other advantages;
- Reduced Operational Cost: Infrastructure is only used for a specific time when the user has made a request, so it implies fewer runtime costs.
- Ease of Development: Developers are more focused on core features as they don’t have to handle the cloud. Managing infra is done by cloud providers.
- Lower Latency: Since code doesn’t need to be hosted on the origin server, it can be run from anywhere. Latency is reduced as requests have to no longer travel from origin.
Serverless Not to be Confused with FaaS
Serverless means you don’t have to take authority of the server or its administration, it’s handled by some cloud platforms and this platform sits between frontend and database.
FaaS is server-side logic that is maintained by developers and not by cloud providers. It runs on a stateless container and is managed by a third-party vendor. Here front-end code is uploaded to the service and providers take care of the complexities of the backend.
Prevailing Trends in Serverless in 2021
Serverless technology has become mainstream and has begun to draw attention to creating scalable, professional, and future-oriented applications. It is widely used in the industry to provide robust and scalable applications. Therefore, you need to keep up with the trend in serverless technology to take full advantage of this cutting-edge technology.
- Serverless Kubernetes: The serverless mode on Kubernetes is a portable solution that allows you to run applications wherever Kubernetes is running. The serverless version allows developers to use their own cloud infrastructure to easily deploy, monitor, and run these applications.
- Serverless Hybrid Cloud : If you are looking for tools to monitor, manage, and protect hybrid serverless environments, cloud administrators should check out open-source projects. Knative is a Kubernetes-based platform for driving DevOps workflow, is used for the unified development of containerized and serverless applications for configuration on public and private cloud platforms.
- Serverless in Stateful Application: Cloud companies can take their applications to a new level. Distributed enterprise applications can be Stateful, recover automatically, quickly recover from disasters, and scale at the infrastructure and application levels, with minimal reliance on centralized databases.
By expanding the database to serverless or copying the cache system, large amounts of data can be processed relatively quickly. By event sourcing, functions catch up to the current state while starting up.
Future of Serverless
Serverless development requires serverless computing, as well as serverless storage. Technological advancements in the cloud have paved the way for serverless computing, which has the potential to provide better scalability, business and workflow stability, and cost-effective solutions. With top high-end potential development trends in serverless such as FaaS, Serverless IoT, Kubernetes, organizations can accord themselves by embracing these trends with massive benefits that adhere to serverless computing.
