On The Road to Serverless Architectures

In today’s day and age, digital transformation has almost become a way of life. All organizations today want to become tech companies, because tech disruption is the present reality. Imagine a time where all of your developers’ time could be spent on building apps and deploying them directly, without having to worry about servers. That time is now. We’re talking about serverless architectures. Using this architecture means constant innovation on the job, while facilitating a holistic integration of IT and business roles.

Built on a fully managed service model, serverless computing lets you take your mind off infrastructural concerns and expensive monolithic architecture based on legacy systems that are now a thing of the past. Microservices enabled an architecture that is more cost-effective, flexible and scalable than its predecessors is the need of the hour. Gone are the days where servers would occupy floors worth of office space. With this comes no physical liability and pay per use services, and the faster it runs, the less you pay. In the near future, serverless architecture is bound to play a more central role within enterprises. This is also because it promises business agility, optimal resource utilization and ultimately leads to a seamless customer experience.

While cloud adoption and migration has been in use for many years now, the big three cloud vendors i.e. Amazon, Google and Microsoft Azure have already opened the window of opportunity for serverless technology. Microsoft Azure, through Azure Functions, promises to enhance developer productivity with triggers and bindings, built-in intelligence, machine learning and cognitive services. It also has a SaaS integration and IoT backend that creates intelligent apps without any infrastructural hassles. Google’s mobile platform Firebase has also become pretty popular among developers for its functionality, analytics and crash reporting that betters user experience. Moreover, it is easily scalable and a mix of everything, right from storage, hosting, databases and pre-built cloud architecture. Add in Google integrations, and what you’re looking at is a comprehensive mobile app toolkit, minus any headaches. Let’s not forget AWS Lambda that lets you run the code and trigger it through other AWS services, using custom compute resources as per your requirement. Execute code through AWS S3, DynamoDB, Kinesis or Cloudwatch and Lambda will process it in real time, so you can track the app’s success. So much better than traditional servers, right?

Serverless technology has been a constant buzzword for DevOps this year. For one, they share the same goal of both is the same: to reduce delivery time when for software development processes. DevOps is becoming the new standard in IT, as it eradicates silos and promises collaboration between teams. In addition to FaaS (function as a service), Docker containers as a service have also evolved. However, many businesses are struggling with DevOps implementation because of a lack of expertise and operational hurdles like faulty tools, legacy processes and fear of failure. Here’s where serverless tech comes into the picture. By using serverless architecture, it is possible to implement an entire build, test and deploy pipeline and write the glue code without using any hosted solutions.

It optimizes time simultaneously and also saves resources. One doesn’t have to worry about code changes either, and servers are always available for use through the cloud. With faster release cycles and higher delivery speeds, updates can be rolled out in real time too. Since this is backed by microservices, complex applications are also broken down into easily manageable modules that make the entire software development process agile.

Serverless computing and architecture manages entire ecosystems when it comes to IT requirements, and combining this with DevOps works like the cherry on the cake. The marketplace is sure to evolve according to these trends, especially for organizations that have already migrated to the cloud. The only thing we need to remember is that disruption is the key, and while the path to IT excellence is a long and winding road, the end goal is always worth it!
