What is Cloud Migration?

What is Cloud Migration 

The act of moving part or all of your data from your own servers to the cloud is known as cloud migration. Cloud migration can also refer to the process of moving data from one cloud platform to another. We all understand that data is a gold mine for every firm, thus it cannot be done as a just like that thing. There is a need for in-depth analysis, planning, and execution, and cloud migration strategy comes into play. 

Cloud Migration Process 

Cloud Migration Process entirely depends upon the industry and the type of workloads. Yet the cloud migration process has some elements which are listed below 

•  Security requirements 
• Performance Evalution 
• Cost  
• Organization 

Cloud Migration Strategy 

Without a clear cloud migration strategy, one cannot move all of their data to the cloud. It can be described as a precise road map. Not every workload can be moved to the cloud at once. This approach aids in prioritizing the most important workloads and creating a migration strategy for each workload. 

Cloud Migration strategy and planning differs based upon the organization and the volume of the data. Here let’s have a look at some cloud migration strategies 

Relocating: The simplest way of migration entails moving VMware virtual machines from on-premises hardware to VMC. 

Reprovision from scratch: This method entails turning on the new ones in the VMware cloud before turning off the old ones in the on-premises system. 

Cold migration: This method restarts the workload that was transferred to VMware; it is effective for non-production workloads. 

Live migration: Practically speaking, you must be able to move a running virtual machine (VM) between your on-premises system and your VMware Cloud on AWS SDDC. 

Replat forming: This model modifies or replaces numerous components in order to more effectively capitalize on the advantages of the cloud provider. 

Repurchasing: When a SaaS program or an app marketplace offers the same functionality as an obsolete on-premises ERP, finance, CRM, or HR solution, this approach is typically used. 

Refactoring: Although it is the most expensive form of moving, the benefits can outweigh any potential drawbacks. Numerous programs that were transferred via a different technique may wind up being refactored as the advantages of cloud-native applications become clearer over time. 

Retaining: This is not a genuine migration because the program is kept running on its present on-premises architecture. If there is still a considerable investment in them or if a critical application is still running on dated mainframe or minicomputer platforms, the company may desire to keep such well-behaved and productive program running while utilizing APIs to communicate with cloud-based services. Therefore, using both public and private clouds, workloads are moved to hybrid clouds. 

Retiring: Every program eventually becomes obsolete, either because of redundant features or because cloud-based services offer better substitutes.

Barriers in cloud migration 

According to statistics, 44% of firms have trouble migrating to the cloud because they lack cloud-based capabilities. Even with a sound strategy, there will still be obstacles and potential issues while moving to the cloud. IT managers may find that their applications perform less successfully in the cloud than they did on-premises. They must identify the causes of the failed cloud migration; these could be issues with compliance, bad latency, or security worries.  

Frequently, the cloud application costs more than expected or performs less well than expected. If a business didn’t have a skilled managed service provider on their side, they would probably encounter the difficulties described below. 

• Migration complexity 
• Legacy Issues 
• Cloud Management 
• Inappropriate planning 
• Business support 

Cloud Migration Testing 

You can’t migrate the entire volume of data once you fix the cloud migration strategy. Cloud migration testing is important for hurdle less data transition.  

The workload should undergo stress testing and performance optimization before going into production. Testing redundant systems and failure scenarios is also essential. While you shouldn’t try to test every potential app feature, you still need to have a firm grasp on a number of performance-related issues both before and after an application is moved to the cloud. Create a testing strategy for cloud migration to verify an application’s baseline performance before and after the move, including application start and response times, as well as to establish suitable security and access, and to ensure effective integrations with other services. 

Security in Cloud Migration 

During a cloud migration, there are particular considerations for the new security realities. When moving data or apps over a network, there is a chance that attack vectors could become available. These assaults could involve malware installation, credential and VM snapshot theft, repetitive migrations, and resource-intensive “thrashing” persistent denial-of-service attacks. 

Understand the shared responsibility model provided by your cloud provider, which describes the areas for which both you and the provider are accountable. For users, this often refers to all elements such as data, access, and governance that are above the underlying infrastructure. Additionally, you must create structures and procedures for governance, access control, and monitoring. 

How to perform a successful cloud migration? 

You can perform a successful cloud migration strategy when you have a managed service provider on your side. They will take responsibility for transmitting your data from servers to the cloud. With MSP you will also have the following benefits on your side. 

• Enhanced Performance 
• Reduced complexity 
• Improved security standards 
• Cost management 
• Choosing with right features
