Existing Cloud Migration

Restructuring existing cloud infrastructure

Cloud Migration Strategy

Adopting a strategy for your existing cloud migration is an essential part of a successful migration. Over 60% of companies have not reaped the benefits they were promised out of cloud initiatives. Business agility, reduced CapEX, flexibly, mobility, efficiency, faster time to market are some of the major reasons why organizations choose a cloud model. Instead, companies are going over allocated IT budgets, experiencing performance degradation and a complete infrastructure shut down at the most critical time.

When faced with such challenge, Gartner 's 5 different strategic R's for application migration to the cloud stands out : Rehost, Refactor, Revise, Rebuild, Replace. While interacting with business owners, CIO and CTOs, we've discovered that many are simply looking for greatness on the wrong cloud platform. Not all cloud computing infrastructure was built for every industry. Better yet, not all clouds are created with you in mind. Public clouds are created for the public. If looking for a more custom or private solution , you are at the right place. Don't let cloud providers dictate your choice, but rather work with a partner who can provide educated and insightful recommendations.

Existing cloud migration - 6 Strategies for migrating applications to the cloud based on AWS assessment . This process — while based on experience — is intended to provide some guiding principles to help you approach your migration and not meant to prescribe hard-and-fast rules.

Rehosting or "Lift and Shit"

When your application code does not need to be modified to fit on the cloud, you could simply "lift and shift". Most of the time, these are stand-alone apps found to be independent from any other processes in your architecture. Migration time here is quick and cost is reduced, but you may be missing out on cloud-native efficiencies which is the main reason for moving away from your legacy environment in the first place. This is Infrastructure as a Service (IaaS) model.
Rehost with confidence


At times, it makes no sense to be wasting resources trying to build the perfect platform knowing there's one already in place you can benefit from. Many cloud providers have the languages, the frameworks, containers readily available for use. Example: Amazon Relational Database Service (Amazon RDS) is great if managing databases is eating up your valuable time. Start looking into Platform as a Services (PaaS) model.
Multicloud replatform


Don't be afraid to admit that your proprietary application or ancient software might be the cause of inefficiency. Be bold and invest in better and modern software. Repurchase or simply move onto a SaaS model all functionalities exist without re-inventing the wheels. Are you leveraging the correct technology to address challenges that are specific to your business or workload?

Refactoring / Re-architechting

A poorly designed application needs to be "refactored" at the code level so that it could scale as needed. In many instances, this also involves changing the architecture on which it resides. By doing so, organizations can boost agility or/and improve service delivery model. As usual, let your workload guide your cloud adoption process as opposed to blindly selecting the most popular on the market.

Retiring - Get rid of

Begin with an insightful inventory of your current IT and start discarding useless clutter. As much as 10% -20% of an enterprise IT portfolio can be turned off without impacting operations. Legacy resources may still exist due to oversight or lack of verification. Freeing up your platform will result in an increased resource pool availability as well as cost savings while reducing your team's focus area.

Retaining - Revisit

Usually this means “revisit” or do nothing (for now). Maybe you’re still riding out some depreciation, aren’t ready to prioritize an application that was recently upgraded, or are otherwise not inclined to migrate some applications. You should only migrate what makes sense for the business; and, as the gravity of your portfolio changes from on-premises to the cloud, you’ll probably have fewer reasons to retain.

What’s Cloud Migration?

Cloud Migration refers to the process of transferring digital business operations into a comprehensive cloud. Many resources refer to cloud migration as a movement from legacy infrastructure to a cloud, but a cloud-to-cloud transfer can also be feasible. This transfer involves relevant data, applications, and IT-related processes from one data center to another.  Similar to physical transfers, cloud migrations require extensive preparation and effort. Migrating your digital entity into a cloud provides efficiency and a substantial amount of savings.
