Migrating From Old Hardware to Cloud Hosted Services
After you have made the business case and appointed your project resources for the migration not it is the time to consider the scope and make plans for your migration. Mainly, the organizations do not make plans for the migration from on-premises or hosted environments to the cloud platform as it is the fundamental misstep that is made by the IT decision-makers. However, it there will not any relevant planning then the cloud will not provide its complete value due to which it will extend the time that is needed for the successful migration. Furthermore, cloud migration is not an infrastructure refresh where you can take out the old hardware and replace it with the newer but it is an application landscape that you can redesign and it will not only change the way of interaction of IT administrators with your systems but it will also change the interaction of your application with one another as well as how they are delivered to your end-users. There are various factors that you should consider while moving enterprise applications to the cloud environment, some of them are obvious while others are not. Here are some of the guidelines that you should consider while going with the application migration to the cloud –
The use of resources and its availability – Mostly, it happens that the minimum specifications for the application far exceeds the actual usage profile of the organization so you should consider the usage of resources as well as its availability. The minimum specifications show the general operating window that is defined by a software vendor without considering the particular case of usage. In these situations, there is a possibility of gaining the significant efficiencies while architecting the reliable cloud environment so the opposite can be true and the right cloud environment needs to be chosen to match the availability as well as the requirement of the utilization of the resources.
Licensing – You should carefully check whether the application is licensed as per VM, per core, or for the total infrastructure footprint, which can have massive cost implications as well. If the licensing model includes that all the available resources should be taken into account even if these are not allocated to the client then the cost of licensing will increase when migrated to the public cloud platform.
Existing access mechanisms – You should consider how the users are accessing their application and how it will have to change after the migration so, during planning, it is essential to consider how the expected user experience can be affected and how you can best prepare the users.
Security – The organizations should look for the networking but it does not mean that they can avoid the implementation of the security policies as these are necessary for ensuring the required level of security is met adequately and reliably. Also, you need various concessions that are relevant for relaxing the policies as well as the cede responsibility for the particular areas to the providers of the cloud-services.
Integration – Mainly, it happens that the organizations discover the application’s dependencies very late in the process of migrating workloads that result in unplanned outages as well as limited functionality to the systems when these dependencies are addressed.
