However, many organizations think they are tied to their existing data centers and systems, and cannot reap the benefits of migrating legacy applications to the cloud: agility, lower operational costs, improved resilience, and innovation potential. But cloud migration is not just the transfer of applications from on-premise servers to a virtual machine. It needs a methodical, strategic process to mitigate risk and maximise value.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It sets out a 7-step overview for migrating legacy applications to the cloud while meeting business functionality, ensuring performance and scalability in the long term.<\/span><\/p>\n<h3><strong>The Importance of Moving Legacy Applications to the Cloud<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Legacy systems run on old hardware and software infrastructure. These systems can be expensive and resource-intensive to maintain. Moreover, scaling them for the requirements of modern users is difficult and frequently also wasteful.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are several advantages when migrating to the cloud:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Ability to scale elastically as workload fluctuates<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improved performance and uptime<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Enhanced disaster recovery capabilities<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reduced infrastructure costs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Stronger security frameworks<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Faster deployment cycles<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Better integration with modern applications<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Yet migration needs to be a meticulously planned process lest you incur downtime, data loss, or disruptions in operations. A methodical approach will make the process seamless.<\/span><\/p>\n<h3><strong>Step 1: Full Application Audit<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">It explores the current state of your legacy systems \u2014 an important step during cloud migration. In the absence of a qualifying assessment, organizations run the risk of minimizing complexity or missing dependencies.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Analyze Application Architecture<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Determine whether the application is monolithic, modular, or partially service-oriented. Find components that can migrate standalone and those that are coupled with other systems.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Map Dependencies<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Legacy systems are commonly dependent on databases, external integrations, middleware and internal tools.
