Serverless Architecture: Everything You Need to Know
In recent years, serverless computing has gained popularity among companies of all sorts, ranging from cloud-native startups to major corporations such as Netflix and Nordstrom. With serverless computing, teams can concentrate on getting ideas to market faster rather than on managing infrastructure, and what's better is that they only pay for the resources they consume. Serverless architecture lays the groundwork for achieving future business objectives such as agile development environments, resource allocation automation, scaling, and faster response times, amongst other things. Aside from that, you would see a reduction in operational overhead and provisioning for physical infrastructure, which would allow you to get the most out of your financial investment. Learn more about Serverless Technology by reading this detailed guide. We'll dive deep into subjects like function-as-a-service, how serverless architecture works, the advantages and disadvantages of serverless, and how and when to employ serverless technology.
What is Serverless Architecture?
Businesses spend hundreds of thousands on managing legacy IT infrastructure and how they struggle to manage multiple servers and data centers. An excellent solution to this is serverless architecture, a software-design paradigm based on events and instances that eliminates the need for administering, provisioning, and scaling servers and databases. Businesses will be able to run their apps through third-party services, avoiding the need to invest in real or virtual servers in the process. Many cloud service providers deal with the complexity of computing, system administration, and dynamically assigning resources, all handled by their staff. Serverless architecture can be categorized into two models:
- Backend-as-a-Service(BaaS): By using BaaS, Developers can concentrate on maintaining the frontend of apps while having backend development responsibilities such as managing compute servers, cloud storage, and database maintenance taken care of for them by a third-party solution. This rids them of having to manage or create scripts for server-side tasks like database maintenance, user authentication, and encryption due to this architecture. BaaS providers also offer APIs and Software development kits that developers can leverage to build commonly-used functions like authentication into an application at the flick of a switch, shortening time-to-market and decreasing development costs while maximizing productivity.
- Function-as-a-Service(FaaS): It is an event-driven execution model that executes small code blocks. It causes the functions to be invoked when certain events occur in the application modules configured to do so. Excellent cost-efficiency can be achieved by dynamic scaling of resources and simplifying processes. For instance, if the system has to support 100 simultaneous requests, it will assign 100 (or more) copies of your service to accommodate those requests. When demand lowers to two requests running concurrently, it eliminates the ones that are no longer needed. You only pay for the resources your functions consume, and you only pay for them when your functions consume them.
Serverless: Applications and Common Use-Cases
- The business expects feature addition, as well as other sophisticated scaling requirements, in order to satisfy unpredictable workloads for fast changing developmental needs.
- Products involving dynamic resizing of images or video transcoding to simplify multimedia processing for different devices.
- Creating real-time applications with high latency, such as multimedia applications, in order to perform automatic memory allocation and complicated data processing.
- In order to develop safe customer delivery dispatch systems and to aid in the development of dynamic resizing capabilities
Advantages of Using Serverless architecture
Here are some of the widely-accepted benefits of switching to serverless architecture pattern:
- As a business, you could become more agile, take up innovative, entrepreneurial projects, and obtain a competitive advantage that can help you lead your industry forward.
- Because serverless architecture executes business logic/code as functions, you no longer have to worry about maintaining infrastructures on a manual basis which can help you cut down on your IT payroll expenses.
- You will be able to deploy apps more quickly and be more flexible in your release schedule. Serverless makes it possible to deploy code in minutes rather than hours or days by utilizing a CLI.
- Applications can be scaled up or down dynamically on-demand and on an as-needed basis, depending on their usage which results in optimal performance ensuring a seamless user experience for each user that uses your products.
- It also eliminates much of the security requirements around maintaining legacy infrastructure since it is now the responsibility of the cloud service provider.
Limitations of Serverless architecture
- The debugging and monitoring tools you use will be provided by your service providers, and you'll have limited influence over the architecture and availability of the platform.
- Long-running workloads may prove to be more expensive to run on a serverless platform than on a dedicated server platform.
- While processing the cold-start request and running functions, you may observe delays in the response time. You might, however, circumvent this by sending repeated queries to the server to keep the server in an active state.
