Gartner has rolled out its series of predictions for 2022 across various disciplines. Within the realm of applications and software engineering, they are highlighting the evolution of cloud computing into a component of overall organizational strategy from simply an exploratory technology. They also showcased the need for modernized software, technologies, and practices such as serverless computing and the software architectures that support it. One of the key takeaways for this second prediction is that they foresee that roughly 60% of new event driven applications, which allow businesses to better serve customer needs, will be using serverless computing.
For many organizations who are looking to take advantage of these trends, there is a crucial step to getting there — legacy application modernization. As you start to think about providing solutions to your customers that are scalable and can react to information in real time, the shortcomings of applications using older architectures or written in old programming languages become quickly apparent. For example, to get the most out of the move to the cloud, there are certain architectural elements to take into consideration such as creating composable elements like microservices and decoupling data and services. Older applications tend to be built in more of a monolithic fashion, resulting in necessary testing and re-deployment of the entire application for any single change made. The benefits of agility and scale that come with the cloud cannot be maximized if this architecture is left unchanged.
Moreover, any successful application modernization effort must start with having a foundational understanding of your older applications. And in many cases, these applications are not properly documented and/or are written in languages where the talent needed to support them is becoming harder and harder to find. Without a firm grasp of what your application does, simply moving it to the cloud doesn’t ensure optimized performance. You may be including unnecessary dead code or redundancies or even be running outdated logic without realizing it. So, it’s important to start by creating documentation artifacts for any applications that you feel could benefit from some of the above-mentioned application trends. With that information in hand, you can then take the next steps for deciding which applications to modernize and how to modernize them in order to ultimately make the move to cloud computing models in relevant parts of your business.
