Cloud technologies can transform business organizations and elevate them to the top echelons of their industries. However, cloud adoption often means migrating traditional architectures to the cloud, modernizing existing cloud-based architectures, or a combination of both.
Recent statistics highlight the irreversible growth trajectory that cloud technologies, and those who adopt them, are witnessing. The estimated value of the global cloud computing market will see a figure of $1,240.9 billion by 2027, and as we enter 2023, specific trends are shaping cloud migration and cloud modernization strategies. So, it is wise for businesses to stay educated about practices and critical trends.
Traditional, on-premise server and VM deployed application portfolios deteriorate over time and gradually lose business fitness, innovation support, and agility while becoming increasingly expensive, complex, and risky to maintain. Software engineering leaders and enterprise application leaders can use various approaches to continuously improve the fitness and value of their applications, so that they can better support changing business demands, with application migration and modernization being a popular vehicle to kick start the cultural and process changes necessary to take advantage of these modern approaches.
According to the 2023 Gartner CIO and Technology Executive Survey,[1] 46% of organizations will increase their spending on application modernization, and 50% will increase their spending on cloud platforms in 2023. Also, 47% will decrease investments in legacy infrastructure and data center technologies, illustrating the transition to modern technology platforms.
There is no one-size-fits-all approach for a migration and modernization project. However, using a methodology such as Gartner’s 6R’s (Rehost, replatform, refactor, rearchitect, rebuild, and replace), can help to categorize applications in terms of the effort, value, cost, risk, and business impact involved. Business organizations must be part of the process of selecting the migration and modernization approach for their applications, because when business leaders choose the path of least effort, they may save time and upfront cost, but fail to reduce the underlying technical debt within their application portfolio or achieve the strategic goals of their migration. Consequences of choosing the wrong migration path often include high operating costs, low realization of business benefits, poor availability, business process disruptions, unmaintainable code, and early termination of the modernization initiative.
