As cloud computing is growing at a rapid pace, enterprises and IT organizations are increasing adopting the cloud with a focus on infrastructure-as-a-service. As per the recent report by RightScale, 95% of respondents agree to using cloud with 77% private cloud adoption and 71% hybrid cloud adoption in 2016.
Considering these figures, it is apparent that more and more organizations are keen to migrate their mission-critical applications and systems to cloud to leverage the benefits of storage optimization, security, capacity and performance. However, migrating to the cloud is not easy as it may seem. It involves complex processes which may pose unpleasant surprises in consort if the process is not carefully and precisely detailed in advance, and if the service provider you’ve hired is not technically sound.
However, with care planning and adopting the right steps, cloud migration can be done easily and efficiently. Here are the tips you can follow to ensure a successful application migration to the cloud:
1. Assess Requirements and Tasks
Before you start planning to migrate your application to the cloud, it is important that you assess and understand the requirements since complex issues may arise during or post-migration process. To do this, you should validate the complete program code, the design, and application program architecture. Also, you need to create a robust, comprehensive cloud migration strategy with the service provider to avoid any critical issues. Along with this, it is also important to assess the tasks and processes to be carried out as per the cloud model selected and workload should be divided into phases to resist the possible risks.
2. Analyze the Migration Process
Once you are done with assessing the requirements, you need to start analyzing the migration process. This will help the system engineers understand the complexities associated with the application migration and accordingly, execute the migration process. Moreover, it will clear the requirements regarding the software components, data, and functionalities that can be migrated to the cloud and the ones that can be skipped.
3. Redesign and Re-Program
As the engineers are well-aware about the complexities associated with the migration, it is advisable to redesign the entire application and process architecture before migration. For this, you need to choose the components and data in the shared service center for migrating to the cloud. Once the components to be migrated are finalized, it is time to re-architecture and re-program the entire enterprise application. Further, the re-programmed application needs to be re-integrated with the cloud-based application environment for implementation over the cloud. Following this practice will again help you avoid any undesirable consequences in the post-migration phase and ensure the system and processes work accurately in the cloud environment.
4. Perform Automated and Continuous Testing
Testing is one of the essential parts to make sure there are no adverse effects in the working of the application or processes post migration. It is advisable to perform continuous testing with different cloud-specific test cases and scenarios, which helps you identify different errors associated with the application, integration environment, and functionalities to resolve them before it leads to a major break-down due to severe bugs. You can also resort to automated testing which will help you speed up the process and optimize the testing coverage with lesser resources while the migration is going on.
Automation tools like TestMaker, Apache JMeter, TestingWhiz, etc. are the best available tools to test applications on the cloud.
5. Take a Backup
It is advisable to take a backup of all the large as well as micro-level programs that depend on the input from the existing enterprise system. This will help avoid any future breakdown of processes and loss of data during and after the migration process. Also, the backup will help resume the system processing faster post migration and deployment phase.
6. Manage Cloud Program and Conduct Training
Lastly, to bring in more benefits of cloud computing, make a practice to manage and synchronize the application, data, and environment. This will help you keep track of all the latest changes and development in the application and avoid possible turbulence in the program. Also, it is advisable to train the employees appropriately to ensure they’re comfortable using the cloud applications and tools.
Apart from following the above tips, it is important that you choose the right service provider who comprehends the requirements correctly and uses the best methodology to ensure you leverage the benefits of a successful migration to the cloud.
