With legacy systems and old hardware, you often have to worry about maintenance, upkeep, rigid licensing agreements, long-term contracts, and the eventual need to replace these systems. With cloud, you can kiss these issues goodbye as it eliminates the concerns of application life cycles. You can pay for what functionalities you need, and can install updates as soon as they come. Plus, there are no rigid and long contracts that you have to sign.
Cloud is a boon to the modern world of digital technology and has the potential to change everything that we see today. It can make you fast, reliable, and more accessible to your customers, and that itself is a big reason to migrate to cloud in the year 2021.
