The new age enterprises prefer deploying applications and store data in the cloud to avoid creating an on-premise IT infrastructure. Likewise, many enterprises are moving their applications and data to the cloud to avail benefits in terms of scalability (One of the predominant advantages of Cloud Migration!), accessibility, speed, compatibility, and cost. But enterprises must implement a robust plan to deploy applications efficiently and store data securely in the cloud. The decision makers must keep in mind the pros and cons of cloud computing while preparing the migration plan. At the same time, they need to consider a number of factors before getting started with cloud computing.
Broadly, cloud migration service provider gives enterprises an option to choose from three distinct forms of Cloud Computing – private cloud, public cloud, and hybrid cloud (Are you planning to move your application to hybrid cloud?). The private cloud allows enterprises to avail dedicated data center and infrastructure. But the enterprises have to deploy skilled engineers to manage the entire infrastructure and data center. On the other hand, an enterprise has to store data, virtual machines, and other computing resources in a publicly accessible infrastructure when they opt for public cloud. They can even access the infrastructure on a per-user basis without investing in specific hardware. An enterprise can opt for a hybrid cloud to integrate private and public cloud services with on-premise infrastructure. It is always important for business owners to compare the pros and cons of these cloud-based infrastructures.
Likewise, they can choose from three types of cloud computing services – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Each of these cloud computing models allows enterprises to avail specific computing resources based on a pay-as-you-go model. But IaaS enables enterprises to avail remote servers and data centers along with network equipment, whereas SaaS enables access to licensed software over the internet. At the same time, PaaS allows enterprises to access software framework and hardware architecture remotely. Hence, it is always important for the enterprises to decide the most appropriate cloud computing service based on their computing resource requirements.
The businesses have the option to choose from a wide range of cloud platforms and cloud-based services. But they must remember that the worldwide market share of a cloud platform does not reflect the quality and reliability of its cloud services. Each cloud platform has its own pros and cons. The business owners must evaluate the pros and cons of each cloud platform based on a number of parameters – availability, accessibility, elasticity, compatibility, speed, security, and cost. It is also a good idea to prepare a comprehensive list of computing resources required by the enterprise, and ask the cloud service vendor specific questions to ensure it meets their precise needs and budget.
The cloud platforms enable enterprises to build, deploy, and run applications without building and maintaining on-premise IT infrastructure. But the enterprises must remember that cloud computing also has its own advantages and disadvantages. There are species that cannot function and perform optimally in the cloud. For instance, no enterprise should consider migrating applications to the cloud that require additional bandwidth or deal with critical business information. That is why; each enterprise needs to create an elaborate cloud migration plan. The cloud migration plan will help the decision makers to identify the applications that can be moved to the cloud and determine the computing resources required to run the applications in the cloud.
Once the enterprise moves its applications and data to the cloud, the resources will remain on remote and virtual infrastructure. The enterprise will lack the option to control or customize the cloud-based environment on its own. As the cloud-based resources are accessed over the internet, it is not possible to eliminate technical issues and downtime. There are also chances that the cloud service vendor may require time to fix new issues and defects. Hence, it becomes essential for enterprises to complement the cloud migration strategy with an elaborate disaster management plan. The disaster management plan will help the businesses to protect their applications and data despite downtime and geographic server failure.
On the whole, an enterprise can easily avoid creating and maintaining on-premise IT infrastructure by developing, testing, and deploying applications in the cloud. But it is always important for the enterprise to choose the right cloud platform, cloud computing service, and cloud service vendor according to its precise needs. The decision makers even need to consider a number of factors to leverage benefits of cloud computing fully.
