Cloud Migration Planning by Automatic Infotech

Moving to the cloud can be a daunting task for many companies, especially for the IT department. Concerns about the impact on existing business operations, data security, compliance, and more are critical factors that often arise.

At Automatic Infotech, we understand the challenges of cloud migration and offer expert consulting to ensure that your cloud migration strategy is based on professional inputs and industry best practices. 

A successful enterprise cloud migration strategy will include prioritizing workloads for migration, determining the correct migration plan for each individual workload, developing a pilot, testing, and adjusting the strategy based on the results of the pilot. A cloud migration strategy document should be created to guide teams through the process and facilitate roll-back if necessary.

What are the types of cloud migration strategy?

There are several options when considering workload migration.

Rehosting (Lift and Shift)

Perhaps the simplest form of migration. As the name implies, this involves lifting your stack and shifting it from on-premises hosting to the cloud. You transport an exact copy of your current environment without making extensive changes for the quickest ROI. Companies with a conservative culture or no long-term strategy for harnessing advanced cloud capabilities are well suited for rehosting.

Replatforming

As a variation on the lift and shift, replatforming involves making a few further adjustments to optimize your landscape for the cloud. Again, the core architecture of applications stays the same. This, too, is a good strategy for conservative organizations that want to build trust in the cloud while achieving benefits like increased system performance.

Repurchasing

This means moving your applications to a new, cloud-native product, most commonly a SaaS platform. The challenge is losing the familiarity of existing code and training your team on the new platform. Even so, repurchasing might be your most cost-effective option if moving from a highly customized legacy landscape.

Refactoring

Refactoring (or rearchitecting) means rebuilding your applications from scratch. This is usually driven by a business need to leverage cloud capabilities that are not available in your existing environment, such as cloud auto-scaling or serverless computing. Refactoring is generally the most expensive option, but also the most compatible with future versions.

Retiring

Once you have assessed your application portfolio for cloud readiness, you might find some applications are no longer useful. In this case, simply turn them off. The resulting savings might even boost your business case for applications that are ready for migration.

Retaining

For some organizations, cloud adoption does not yet make sense. Are you unable to take data off premises for compliance reasons? Perhaps you are not ready to prioritize an app that was recently upgraded? In this case, plan to revisit cloud computing at a later date. You should only migrate what makes sense for your business.

Benefits of defining a cloud migration planning strategy

  • Cost and time savings are a major benefit of a well-planned cloud migration.  Migration can take months or years if source and destination platforms are different. With consistent infrastructure and consistent operations, migrations can be automated, and workloads moved on masse without any downtime.
  • Many organizations undertake a cloud migration to support overall IT modernization efforts. Organizations that adopt a cloud-native approach utilizing micro-services and APIs naturally use cloud providers – frequently more than one – to deploy modern, containerized application workloads. Additionally, since cloud providers utilize the most modern servers and storage, organizations no longer need to plan for technology refresh, and can instead focus efforts on solving business problems without worrying about upgrading memory or OS in a server.
  • Instant scalability can be realized by migrating to public cloud providers, enabling enterprises to meet changing demand at will, whether fluctuations are caused by seasonality, business growth, or another spike. Cost savings can be considerable since resources are only paid for while in use.
  • Security can be improved by cloud migration strategy as well. Although most cloud providers utilize a shared responsibility model, cloud infrastructure is typically far greater than an organization’s own on-premises infrastructure was. Most cloud providers offer security analytics, block unwanted traffic, and ensure OS and security updates are applied with no action required by user organizations. Additionally, cloud-based applications and data are always available regardless of the status of end-user equipment. 
  • Accessibility is greatly enhanced by cloud migrations. Since applications and data can be accessed from virtually anywhere, employee productivity likewise improves since workers can access business-critical applications and data from home, while on the road, even while at the office exactly as they had in the past. Additionally, since business applications and data are now in the cloud, machine downtime does not cause loss of access and operations can continue virtually uninterrupted.
