A Short Introduction to Serverless Architecture
We have progressed a lot since the days of mainframe computing. From having computers the size of entire rooms to going completely serverless, computing has evolved rapidly over the decades. Serverless architecture or serverless computing enables applications to be hosted by third-party services for use. It skips the need to own server software or hardware.
Components of Serverless Architecture
Even though the serverless architecture suggests that there are no servers involved, it is not true. It is simply the case of servers being available remotely, making it convenient for businesses to get access to high-end software solutions without needing to invest in dedicated hardware. Serverless architecture is composed of two elements – IaaS (Infrastructure as a Service) and PaaS (Platform as a Service).
Infrastructure as a Service:
IaaS offers virtual servers that are available in the cloud. All data is available on the internet with backups being stored in physical drives. There are a number of cloud service providers who offer IaaS solutions for businesses of various sizes. It has helped business owners grow their brands without needing to invest in expensive servers and their maintenance costs.
Platform as a Service:
PaaS essentially is a term used for application platforms. Some popular examples include Node JS Express and Python Flask. PaaS solutions are targeted to enterprises and organizations. As a business owner, you do not need to invest resources in managing and deploying applications. They are available on the cloud for from professional PaaS providers for a free which is almost always more affordable and efficient than setting up server-based computing yourself.
Uses of Serverless Computing
Serverless computing can be applied in a number of scenarios and here are some of the most common scenarios it can be implemented in.
Serverless computing can make inter-team collaboration much simpler in businesses. Development teams can deliver high-quality software much faster; there is a higher level of ownership and autonomy. Serverless computing can be used to send alerts whenever various stages of application development are complete.
A number of businesses that employ serverless architecture are moving to single page applications built on the infrastructure. It enables backend cloud-based APIs to power quality applications through Cloudfront distributions which is extremely efficient.
Serverless architecture not only allows enterprises to build quality web apps, but it also enables businesses the ability to analyze user behaviour. Serverless technology is used by organizations to study data lakes containing personally identifiable information of users. Analytics events can be studied through serverless computing applications like S3, Athena, and QuickSight. Data streams can also be used for collecting data from kinetics events.
Batch processing is one of the best use cases for serverless architecture. One of the biggest problems of classic architecture is load spikes. Traditional systems fail to strike the right balance between reacting to a batch of tasks and keeping infrastructure costs in check. With serverless architecture, you have to worry about neither, and you can scale your batch processing tasks efficiently.
Serverless architecture is deal for building workflows for businesses, and multiple specialized services can be deployed for best results. FAAS solutions can enable businesses to have a connected ecosystem for organizational tasks, and serverless technology is definitely the future of computing.
