Cloud Migration refers to the virtual infrastructure which is accessed via the internet or a network. It is an on-demand product or service that is delivered through the model known as infrastructure (a basic model of delivery of cloud computing). You can create your own IT infrastructure which includes storage, processing and networking resources which can be configured in any way. It gives more flexibility to the design of the infrastructure as it can be easily set-up, deleted or restored.
Features of Cloud Migration
1.On-demand services and Self-service
Cloud Migration is primarily based on these two service models. It allows you to interact with the cloud and perform tasks like deploying, scheduling, managing, and building. The user must be able to access computing capabilities when required without any interaction with the cloud service provider.
2.Elasticity and Reference Pooling
The resource allocation must change appropriately and quickly with the change in demand. The system should be elastic enough to transform itself in no time if there is an increase or decrease in the market.
Here, resources are pooled to act as a servant for a large number of customers. It uses multi-tenancy where various resources are allocated dynamically and are de-allocated according to the demand.
3.Quality of Service
It assures the best services rendered for every level of users. It includes guarantees on performance, bandwidth, availability and adequate resources. If there is any compromise on these guarantees, it might prove fatal for customers.
It does not have any upfront costing and is wholly based on usage. You are bill based according to the number of resources you use. It helps you to track the usage and finally reduce the cost. It should provide means to monitor, capture and control usage information for billing accurately.
Benefits of Cloud Migration
Moving to the cloud can solve many problems of the user, some of which are given below:
- When an increase in the traffic of your application makes it difficult to meet the demands of the customers.
- Reduction in the costs of operation, while making the IT processes efficiently.
- Quickly executing the application processes and paying attention to development while maintaining the infrastructure costs.
- When the customer wishes to expand their business, but an infrastructure spread over multiple countries will become a challenge for you.
- When storage requirements continue to grow and become costly and difficult to take care of.
- When you aim to build a development team which is focused and widely distributed.
- With the help of cloud computing, the employees will be able to work seamlessly over the web.
Risks of Cloud Migration
Usually, your particular surroundings contribute to the possible dangers. But, there are some shortcomings of cloud migration which you must keep in mind:
- Maintenance of sensitive and confidential data might be problematic. Compliance requirements can play a role in limiting your options.
- There is no reason to play with your current setup if it is hassle-free, efficient and works smoothly.
- Registered technologies are not allowed to be moved to the cloud.
- Inactivity of some applications may give rise to issues.
- The privacy of any user is a concern if the hardware is shared with others.
- Cloud platform: Leaving or moving between platforms can be tricky.
