Several businesses are in the process of migrating their applications to Public Cloud which seems quite justified considering the growth and popularity Public Cloud is witnessing in the current time. If you too are planning for the same, you need to make some considerations well in advance.
In this blog post, we will take into account all major considerations that you must pay importance to before migrating your app to Public Cloud.
Overall Scene has changed for Public Cloud...
Public Cloud's utility for enterprises has been felt quite lately yet largely. It has been demonstrated by Public Cloud service providers that Public Cloud's reliability is almost near to that of on-premises infrastructures.
Concerns related to security have been resolved well too. Building new apps for Cloud infrastructures is also starting to make sense now. The next logical question that arises now is that which all applications are suitable enough for migration. A wide variety of enterprise applications can be hosted in Public Cloud.
Initially, a specific type of application may not seem suitable enough for hosting in Public Cloud. Let's take a look now at the checklist to follow before actually migrating your apps to Public Cloud.
Virtualized infrastructure...
One of the fundamental questions to ask in this regard is the manner in which workloads like applications get shifted to Cloud. Given below is another way to do so -
- Select a pre-built OS image
- Re-install the app from binaries
- Replicate the data set
We are considering basic x86 virtualization, a virtual-to-virtual (V2V) migration, from the practical perspective. Hence, in case, your app runs on a virtual infrastructure, it is suitable enough for migrating to Public Cloud.
Redundancy...
The availability of the underlying Cloud infrastructure is always taken into account for applications to be migrated to Public Cloud. You need to take into consideration an application's availability before migrating it to Cloud actually.
If your application requires 99.999% uptime and you have built a highly redundant infrastructure for supporting the uptime requirement, it’s a must for you to re-think before migrating the app to Cloud.
Licensing...
Software licensing plays a crucial role too. Punitive licensing models are being deployed by many software vendors for virtualized environments. A similar transition is being witnessed in the realm of Cloud. Additional licensing for Cloud may be required by some specific software and operating systems.
Looking into the database layer is an effective way to counter this challenge. You must find out initially if the database engine being leveraged has licensing for your Cloud provider.
Support...
Another critical consideration quite similar to licensing is the software vendor support. Several business critical applications have tough requirements revolving around the supported infrastructure. Consider for example the strict requirements posed by in-memory analytic platforms on memory and CPU combinations and supported storage configurations.
No doubt, your software may work technically well in the Public Cloud; however, when some issues occur, your software provider may provide limited or almost no support at all.
These are the points you need to consider essentially before moving your enterprise applications into Public Cloud.
