Using cloud migration to power digital transformation

by Justin Augat, VP of Product Marketing at iland.

Cloud is no longer just a way to streamline processes, it’s a major differentiator. The cloud has become essential to businesses thriving in an ever-changing world. Migrating to the cloud has become one of the most vital aspects of being an effective, modern business.

Digital transformation has been the leading edge for many businesses trying to become more agile and competitive.  However, many businesses have not yet fully embraced the potential of the cloud. This is despite the fact that owning and running physical servers and data centres is comparatively more expensive costly and requires considerable effort to maintain. 

The cloud is the way forward, but are some companies may be reluctant to go for digital transformation? 

Making the cloud the core of your digital business

One of the reasons for delaying a move to the cloud is an ongoing attachment to on-premise data centres. For many enterprises, data centres are not built overnight, they take time. Many companies continue to add capacity as they run out of compute power for their workloads and, in some respects, this is the path of least resistance. But there comes a point when companies need to ask if adding capacity to on-premise infrastructure is the right thing to do? The corporate data centre is the biggest source of pain but also probably the biggest source of investment too.

Caution is required in moving workloads and applications to the cloud, especially in heavily regulated industries.  But leaving everything on-premise and creating or supporting a private cloud infrastructure requires ongoing OPEX costs and onsite equipment to maintain and cool.  

While many enterprises have adopted VMware in their on-premise infrastructure, not all have fully embraced the cloud for all their applications. When moving to the cloud organizations have many options to help concentrate their efforts on digital transformation.

If an enterprise has been developed on VMware, it can be a logical move to port such applications to a cloud environment. Still, many don’t realise that the cloud enables them to be in complete control of the applications while gaining operational efficiencies and allowing the firm to focus further up the stack.

Organizations have looked upon cloud migration as either keeping some things on-premise as a private cloud, or other things onto the cloud. Keeping a leg in both environments can helpful, but this raises other issues. Can workloads in private clouds talk to ones in the public cloud? Can workloads on different public clouds talk to each other.

This can be complex, so can we make the migration seamless?

Virtualisation is key to migration

Virtualization is essential to digital transformation and migrating workloads into the cloud.  Moving such workloads becomes easier when the hypervisor in the on-premise infrastructure is the same as the one on the public cloud.

Moving a VMware workload from on-premise to a cloud can be easy enough when the destination is also VMware-based, but a different story when it comes to moving to Azure or Amazon. Here, things get complicated and often need the help of expensive consultants to figure out not just the networking, storage and compute size, but also the cost, as this can be opaque.

This can hold cloud migration projects back and stifle innovation. Spending time configuring workloads means businesses have slower speed to market and uncertainty about costs acts as a brake on project delivery. So, it is important to select the right cloud destination, one that can support existing workloads and a straightforward, uncomplicated migration process.

Popular paths to cloud migration

Once the decision to move to the cloud has been made, there are a number of paths that your business can choose.

• Rehosting: also referred to as “lift and shift,” is the simplest way of moving to the cloud. In this case, applications are simply re-hosted in the cloud, and code copied to the new environment without any changes.
  
  
• Replatform: This is where code is migrated to the cloud but updated to meet the requirements of the new infrastructure.
  
  
• Refactoring: This is a more complicated method of migration. The application’s architecture is completely reconstructed and parts of the code rewritten to ensure it can operate in the new cloud environment.

Getting up to speed

Digital transformation is now top of mind for virtually every CIO as the cloud has a marked effect on how business operations are arranged. CIOs have to ensure that the technology they buy into produces a return on investment and improves performance. Cloud is vital in building a digital-ready infrastructure. It allows business to build rapidly, run more quickly and work anywhere.

Businesses survive by being agile and getting new solutions to market. Having to provision infrastructure is another overhead to deal with in terms of cost, management and timing.

Having a cloud hosting solution that makes cloud migration as easy as pressing a button and moving a workload onto a familiar platform can take the risk out of an enterprise’s digital transformation and leave them with all the options they need in a multi-cloud future.
