Cloud Migration and Sustainability: Understanding the real benefits

One area worth reviewing is the continued use of physical servers. For some organisations, moving suitable workloads to the cloud can reduce the amount of equipment they need to operate and maintain on-site, but how significant are the benefits, and is cloud migration always the right answer?

Traditional on-site servers require electricity to operate. They may also require cooling, networking equipment, backup power and ongoing maintenance. For organisations running several servers, these requirements can contribute to overall energy consumption, and as equipment ages, maintenance and replacement become additional considerations.

Of course, some organisations have valid reasons for retaining physical infrastructure, and the important question is whether that infrastructure remains the most appropriate and efficient solution.

Not necessarily, cloud computing still relies on physical data centres, which consume electricity and other resources. The overall environmental impact depends on factors such as the efficiency of the existing equipment, the cloud provider’s infrastructure, workload requirements and how the new environment is configured.

For example, moving an inefficient, lightly utilised server to an appropriately sized cloud service may offer efficiency benefits. However, moving workloads without reviewing their requirements could result in unnecessary cloud resource consumption and costs. That’s why sustainability claims should be supported by evidence wherever possible.

Environmental considerations are only one part of the cloud migration conversation, depending on the organisation and the solution, cloud services may also offer:

Greater flexibility – Cloud resources can often be adjusted as requirements change.

Improved accessibility – Cloud-based applications and services can support secure access from different locations.

Different approaches to resilience – Cloud platforms offer options for backup, redundancy and recovery, although these must still be configured and managed appropriately.

More predictable infrastructure planning – Organisations may be able to reduce some capital expenditure on hardware, although ongoing cloud costs need careful management.

Cloud migration should begin with an assessment of existing infrastructure and business requirements. Useful questions include:

• Which applications and services are currently hosted on-site?
• Are any systems dependent on particular hardware?
• What are the current operating and maintenance costs?
• How much capacity is actually being used?
• What security and compliance requirements apply?
• What would the ongoing cloud costs be?
• How will performance, backup and recovery be managed?

It’s also important to consider the potential disruption associated with migration and whether work can be scheduled around operational requirements. For schools, for example, holiday periods may provide opportunities to complete infrastructure changes with less disruption to teaching and learning.

Cloud migration shouldn’t be treated as an automatic solution to every infrastructure challenge, but it can be an opportunity to question whether existing technology is still the best fit. In some cases, organisations may find they can reduce unnecessary physical equipment, whereas others may find a hybrid approach or improvements to existing infrastructure may be more appropriate. The objective should be to identify a solution that meets operational requirements while making efficient use of resources.
