The migration of enterprise applications to a public cloud enables organizations to eliminate the overheads associated with on-premises infrastructure. There are 3 key methods for migrating to Oracle Cloud Infrastructure (OCI):
- Rehost (i.e. “Lift and Shift”)
- Replatform (i.e. “Lift, Tinker and Shift”}
The migration strategy selection process is not a straightforward one. It requires intense diagnosis. In this blog under our knowledge video series “TechBeans”, we’ll talk about “Lift and Shift” method of migrating to OCI.
Before we discuss “Lift and Shift”, in case you are wondering why should you consider migrating to OCI, you must read “Modernize Your Oracle ERP: Why is it the need of the hour?“
In this episode of TechBeans, Manish Asawa, AVP – Enterprise Applications at Clover Infotech, will talk about the “Lift and Shift” method of Migration to OCI.
What does “Lift and Shift” to OCI mean?
According to Oracle, “Lift and Shift” to Oracle Cloud Infrastructure involves taking a snapshot of the application server VM’s on the source environment including the OS, boot record, converting into an Oracle Cloud Infrastructure-compatible format and importing it on Oracle Cloud Infrastructure as a custom Image, and then re-instantiating the image.
If you want to focus on the technology and avoid altering too much of the code, architecture and/or functionality of your EBS applications, then “Lift and Shift” is a good option to consider. The essence of “Lift and Shift” is to quickly enjoy the CAPEX to OPEX and other benefits of Cloud IaaS.
Who should consider “Lift and Shift” approach?
- Organizations that have been using Oracle EBS for several years and believe that they are yet to get attain the desired returns from their Oracle EBS investment but want to kick-start their cloud journey
- Organizations which are facing application performance issues or looking for better scalability and security of their underlying platform
- Organizations that are running Oracle E-Business on a proprietary platform such as Solaris, AIX, HP-UX. It is very costly to upgrade these systems and thus migrating to Oracle Cloud running on Oracle Linux is one of the best options.
In “Lift and Shift” method, you are not making any change in your existing E-Business environment but you are taking advantage of the surrounding tools and technologies to modernize your environment. Once you move your Oracle EBS to OCI, you can leverage Oracle’s Platform as a Service (PaaS) Cloud to modernize your existing E-Business. This includes Analytics, Integration with other Cloud or non-Cloud Applications, BOTs, Blockchain, IoT etc.
For organizations that want to put their applications in the cloud quickly, “Lift and Shift” is the easiest, fastest and least expensive migration method. However, you must be careful when taking the easy road. It needs to be confirmed whether the application is operable when migrating to Oracle Cloud Infrastructure as it is. If it is not operable as is then you must evaluate the required changes and determine the lengths you’re willing to go to make those. Further, you must also evaluate if this leads to reduced performance or exposes you to any risks.
Oracle E-Business Suite has served a splendid purpose on-premise, but running it on OCI has several virtues, and the “Lift and Shift” migration method is the easiest to achieve the same.
