Lemongrass has completed a study on the goals and challenges of enterprise IT leaders who have moved legacy systems onto cloud infrastructure. A key takeaway from the survey, which was completed in January by over 150 IT directors or above in companies with IT budgets of at least $1 million annually, is that enterprises are anxious to achieve the business, technical, and financial benefits of moving legacy systems to the cloud. However, the road to running legacy systems on cloud infrastructure can be rough for companies that fail to plan ahead.
Following are the primary themes and data points of the Lemongrass 2021 Legacy-to-Cloud survey:
- Data access, security, and cost savings motivate cloud migrations. A combined 77 percent of IT leaders responding to Lemongrass’s survey said their primary motivation for migrating legacy systems to cloud infrastructure was either a desire to secure data, maintain data access, or save money. Optimizing storage resources and accelerating digital transformation were other top reasons given.
- Security concerns persist. Considering the importance of data security, it’s no surprise that security and compliance were listed by 59 percent of IT leaders as the top challenge facing enterprises when moving legacy systems to the cloud.
- Cloud migrations are costly. 69 percent of respondents said the typical legacy-to-cloud migration cost between $100,000 and $250,000, and 57 percent of respondents said that somewhat or very rarely do these projects come in under budget. 43 percent of respondents said migrations took too long, 38 percent said costs were too high.
- Skilled personnel is hard to come by. Lack of in-house skills was the top complicating factor for 33 percent of respondents. Database integration experience was cited by 21 percent of respondents as the top skill required for performing legacy migrations, followed by experience with the chosen cloud platform (15 percent), previous migration experience (12 percent), and testing validation (also 12 percent). 68 percent of respondents said it was very or somewhat hard to find people with these skills, and 40 percent said migrations took at least seven months to complete.
- Lessons learned. The top three lessons learned when migrating legacy systems to the cloud were to allow for sufficient time (54 percent); to dedicate sufficient financial and people resources (52 percent); and to ensure you have the correct skills in-house (52 percent). The top three lessons learned when running legacy systems on cloud infrastructure were to allow for sufficient time to manage the application (53 percent); to ensure you have the correct skills in-house (52 percent); and to ensure you achieve the outlined business goals (46 percent).
