Migrating to the cloud from a physical environment – Some key steps
As most of the IT companies opting to augment the pace of migration to the clouds, they are also met with a lot of new challenges. From reducing the gap between the existing physical infrastructures that is available in the cloud to applying advanced approaches of delivering applications, infrastructure and end user access, there are a number of things they should be looking at when it comes to migrating to the cloud.
Deciding on what needs to be migrated
In most cases it is seen that the organizations get confused on deciding what applications to be migrated to the cloud. Experts suggest that before migrating, the management should properly scan though the applications. The most critical applications need to be shortlisted but not necessarily in the first stage of migration. The more complex the organization’s IT infrastructure is, the more unaware it tends to be about many of its critical assets.
Migrating physical systems are important for business operations, however, it can become challenging at times. Primary success may be achieved by moving the less mission-critical applications, though it is recommended to create a full list of applications that need to be migrated, as it will help to select the Cloud service provider according to the precise needs.
Workload in cloud assessment
During the assessment of the cloud during migration, one will discover and identify simple, low complexity and complex workloads. The simple and low complexity during migration is considered as it is not interdependent to run across cloud platform. This type of workload can be automated and run in batches and has the competency to migrate workloads at a single time.
The experts in the industry suggest that cloud migration can be initiated to organize cloud for newer workload. The equipped team may get started to cloud management once they understand the performance metrics and start running non-mission-critical and new workloads in the cloud. The gradual movement of the smaller workloads to the cloud will give a better understanding of the environment and its working. Besides, it will make it easier to counter challenges while shifting the major workload.
Apart from this, there are various other aspects related to the migration of workloads to the cloud, which includes faded visibility into cost analysis, history and performance metrics. This may lead to amplified burden of running cloud workloads besides arousing fear related to billing, performance and cost. It is necessary to make sure that your cloud service provider maintains absolute transparency of such a system so that the business cost and the IT budget are not affected. It is also necessary to make sure that you completely understand the training and support offered by your service provider and also have fair knowledge of the SLA and additional cost involved, if any.
What type of applications to move to the cloud?
What type of applications organizations should move to the cloud? It is definitely an individualistic choice of the organization, but it is always suggested to take an inventory of the data and applications and then deciding which applications are the most important to upload in the cloud. One needs to assess and rank according to the importance of the business. It has to be taken into account how much of the environment is virtual and how much is physical, and then classify any critical components, like specific networking requirements or physical systems. Owing to the complexity of the IT infrastructure, it may be difficult to know about all the assets the organizations have or they are using. It is one of the major challenges for the companies. Therefore it is essential to know what you have before you consider what to move.
Choosing the less critical and migrating less complex applications is best for initial success to launch in the cloud platform, however, understanding the full range of applications will help to select the best provider available to address the needs. By using cloud-based disaster recovery services to start the migration you can become at ease with the cloud operations, especially if your cloud service provider enables self-service DR management and testing. The physical systems are a necessary element and the most trying in migrating to the cloud. They are usually the reminders of the older time and part of the IT environment because they are critical to business operations.
The Amazon Elastic Compute cloud, Rackspace or Savvis are some of the applications that are moved back and forth in the cloud application migration in cloud. There are also certain groups of companies who are looking for the movement of the applications to private clouds or virtualized data centers to save costs.
To summarize, cloud-based application offers many advantages. They include the capacity to gauge IT resources when needed, swiftly launch new applications and guarantee a high level of performance all the time. The migration of applications to the cloud ensures a stable and scalable infrastructure and offers the IT employees the liberty to focus on more tactical ideas that drive digital transformation across the business.
