“Cloud migration is distinctly harder than cloud adoption,” according to the study, which was discussed in a recent webinar with special guest, Forrester Principal Analyst, Lauren Nelson. “Mega-cloud environments are not built optimally for all applications. New apps can be designed to run on these horizontally scaling environments in micro service-based architectures, but existing workloads have structural incompatibilities with these platforms. Force fitting a ‘lift and shift’ approach to migrating some apps, particularly mission critical ones, often results in firms choosing between cost and performance.”
The study, which is based on a global survey of 500 IT decision makers at businesses with more than 500 employees, notes that almost half of the cloud migrators questioned are utilising more than one cloud platform. The study also notes that “many are finding out that each platform has both strengths and weaknesses, and some apps are a better fit for one platform over others.”
Some organisations may still believe in a “one size fits all” approach to cloud migration; however, in practice it is much more complex. Most cloud migrators surveyed take an app-by-app approach and incorporate multiple vendors into the process. Only 32 percent of those surveyed relied on a single megacloud vendor for migration, signaling a preference for multi-cloud.
According to the study, cloud computing strategies have been widely adopted by enterprises, and the migration of mission critical apps to the cloud continues to grow. On average, organisations engaged in active cloud projects today have migrated 44 percent of their apps, and by 2019, this is expected to reach 62 percent.
The study also finds that 49 percent of companies surveyed want the ability to scale resources and costs up and down. Further, 53 percent are migrating to the cloud in order to free up time to focus on their own core differentiators, and 52 percent have embarked on a cloud migration journey to achieve cost savings.
When it comes to selecting a provider, 62 percent of respondents cited performance as a key consideration, with security requirements next at 58 percent, followed by compliance requirements at 50 percent. In addition to selecting the right provider, they must also take into account the substantive internal resources that are required as well, 47 percent cited having more than 50 people dedicated to the process, and almost half of organisations spend over $1 million on human and IT capital to migrate mission critical apps to the cloud.
Other highlights from the study include:
Performance
-
Eighty-nine percent of respondents noted they have experienced performance challenges when migrating mission-critical apps
-
Forty-two percent of respondents cited latency between on- and off-premises applications and dependencies on other apps not in the cloud as the top two performance challenges encountered while moving mission-critical apps to the cloud.
-
As one respondent - a VP at a global enterprise bank noted - “performance means the difference between supporting a customer and losing a customer in our industry.”
Cost
-
Rewriting apps (41 percent), connecting back to the organisation’s data centre (33 percent), and software database licenses (33 percent) were cited as the top challenges associated with cost.
-
Nearly all organisations (89 percent) face challenges associated with cost when migrating mission critical apps to the cloud.
Security
-
Of those surveyed, 48% say security is the most concerning challenge in their migration projects
-
Forty-two percent cite protecting personal information as their most important security challenge when moving mission critical apps to the cloud
“This study highlights how different applications have different use-case characteristics, and reinforces why Virtustream has architected and operates its cloud to address the specific requirements of migrating business-critical applications,” said Simon Walsh, COO, Virtustream. “This approach shortens time-to-value for our customers without compromising on security, application performance and cost efficiency.”
