Serverless, the new buzzword in town, has gotten a lot of attention from both experts and newcomers in the tech industry. Partly because of the way cloud vendors such as AWS have hyped the architecture, from conferences to meetups to blog posts to almost everywhere. However, serverless is more than just hype; it promises the possibility of ideal business implementations, which sounds quite pleasant to the ears and likely light on the budget as well.
What is Serverless Architecture ?
Serverless Architecture is a software design model in which applications are hosted by a third party, eliminating the need for database and server provisioning, management, and scaling. Businesses can use third-party services to run their software applications without having to invest in virtual or physical servers. In a serverless architecture, you only write code. You deploy when you're ready, without regard for what or how it runs. There are numerous cloud providers, such as AWS and Microsoft Azure, that manage the complexities of server management, computing, programming, and resource allocation There are numerous cloud providers, such as AWS and Microsoft Azure, that manage the complexities of server management, computing, programming, and resource allocation.
Components of Serverless Architecture
Function as a Service and Backend as a Service are two common components of serverless architecture. FaaS is a cloud computing service that allows you to run self-contained code snippets known as functions. Your functions are dormant until events activate them. Functions are self-contained, small, fleeting, and serve a single purpose. They are executed and perish. BaaS is a cloud computing service that completely abstracts backend logic that occurs on distant servers. It enables developers to concentrate on front-end code while integrating with back-end logic created by others. Authentication, storage services, geolocation services, user management, and so on are examples of BaaS.
Why prefer serverless Architecture ?
It is highly scalable and available. Scaling traditional applications necessitates an understanding of your traffic pattern. You calculate how much of each resource you'll require and then plan accordingly. Users come from all over the world to use modern applications. A traditional application could be overwhelmed by a spike, which would most likely occur on Black Friday. Your application is highly available in serverless, and it scales automatically as your user base and usage grows.
It is less expensive. The pricing model of serverless architecture is one of the reasons it is gaining popularity among startups. In serverless, the cost of running servers 24 hours a day, seven days a week, and paying for idle time is no longer an issue. You only pay for what you use. Functions have a set amount of time in which they run and then die. The provider charges you based on the number of executions and the amount of memory used by your workload. This assists you in cost-cutting measures.
The time to market has shortened. Server provisioning, maintenance, and infrastructure monitoring are no longer your responsibility. You can concentrate solely on your business logic (code), experiment with ideas, and meet deadlines. Using a virtual server from a cloud provider like Amazon or Microsoft eliminates the need for physical hardware, but it still necessitates some level of management of the operating system and web server software processes. A serverless architecture allows you to concentrate solely on the individual functions in your application code. Twilio Functions, AWS Lambda, and Microsoft Azure Functions manage all of the physical hardware, virtual machine operating system, and web server software. You only need to be concerned about your code.
How Serverless architecture works ?
Serverless architecture is based on the Functions-as-a-Service (FaaS) model, which allows cloud platforms to execute code without the need for fully provisioned infrastructure instances. FaaS, also known as Compute as a Service (CaaS), is a server-side, stateless function that is scalable and completely managed by cloud vendors. The DevOps team writes code that emphasises business logic and defines an event, such as an HTTP request, that causes the function to be executed. The code is then executed by the cloud vendor, and the results are sent to the web app for users to review. Some of the most popular serverless services offered by cloud providers include Microsoft Azure functions, Google Cloud functions, IBM OpenWhisk, and AWS Lambda.
Serverless architecture is an ideal choice for business stakeholders and DevOps teams due to the cost-saving and convenience benefits of on-demand auto-scaling resources and pay-as-you-go services. Despite the fact that the term "serverless" implies the absence of servers, serverless architecture still relies on physical or cloud servers. It is a computing model that eliminates infrastructure operations, allowing developers to concentrate on coding and app deployment.
