Cloud Migration - Is It For You?

Cloud Migration – Everyone is doing it, should you?

Maybe. Migrating applications and infrastructure to the cloud offers several benefits that can positively impact organisations in various ways. Stadia has enjoyed bringing the benefits of cloud computing to many of our clients. It isn't necessarily for everyone, but if you haven't migrated some or all of your applications/infrastructure to the cloud, are you missing out? 


Let's take a look at the various aspects, starting with some of the key benefits:


Cost Efficiency: Buying, maintaining, and refreshing your own hardware can be costly. Cloud computing often reduces capital expenditure on physical hardware and datacentres. You pay for resources as you use them, which can lead to cost savings, especially for small and medium-sized businesses.


Scalability: Cloud services allow for easy scaling of resources up or down based on demand. This elasticity ensures that your applications can handle sudden spikes in traffic or growth without the need for significant upfront investment in hardware.


Automatic Updates: Keen to see the back of those out-of-hours patching rotas? Cloud providers handle hardware and software updates, including security patches and upgrades, reducing the maintenance burden on your IT staff.


Flexibility and Agility: Cloud platforms provide a wide range of services and tools that enable rapid development and deployment of applications. This agility allows organisations to respond quickly to changing market conditions and customer needs.


Global Reach: Cloud providers have datacentres in multiple regions worldwide. This global presence allows you to deploy applications closer to your users, reducing latency and improving performance for a global customer base.


Security: Cloud providers invest heavily in security measures, often surpassing what individual organisations can achieve. They offer features like encryption, identity and access management, and compliance certifications to help protect your data and applications.


Reliability and High Availability: Cloud providers offer robust service-level agreements (SLAs) that guarantee high uptime and availability. Redundancy and failover capabilities are built into their infrastructure to minimise downtime.


Disaster Recovery: Cloud services make it easier to implement disaster recovery and backup solutions. You can replicate your data and applications across multiple regions or datacentres, ensuring business continuity in case of disasters.


Collaboration and Mobility: Cloud-based applications and services can be accessed from anywhere with an internet connection. This promotes remote work and collaboration among geographically dispersed teams.

That is a lot of potential benefits, are there any downsides?

It's important to note that while the cloud offers many benefits, the actual advantages experienced by an organisation can vary depending on factors such as the specific cloud provider chosen, the migration strategy employed, and how well the organisation leverages cloud services to meet its unique needs and goals. Proper planning and ongoing optimisation are crucial to maximising the benefits of cloud adoption.


There are some instances when a migration may not be the ideal solution for some or all your applications and infrastructure. Here are a few examples:


Data Sensitivity: If your organisation deals with extremely sensitive data, such as classified government information or intellectual property, you may have concerns about entrusting this data to a third-party cloud provider, even with strong security measures in place.


Network Latency: In some cases, applications with very low latency requirements (e.g., high-frequency trading systems or real-time control systems) may not perform optimally in a cloud environment due to the inherent latency introduced by internet connectivity and the cloud provider's network infrastructure. Nowadays, there are some clever technical solutions available to help get around many network latency issues.


Cost Considerations: While cloud computing can be cost-effective for many organisations, it may not be the most cost-efficient option for all workloads. In some cases, especially with consistently high and predictable workloads, on-premises or co-location solutions might be more cost-effective in the long term.


Lack of In-House Expertise: Migrating to the cloud and managing cloud resources effectively requires a certain level of expertise. If your organisation lacks the necessary skills and resources to manage cloud deployments, it may result in security vulnerabilities, performance issues, or cost overruns. If this is a concern for you, it probably makes sense to speak with the experts. Our contact details can be found at the end of this article.


Hybrid or Multi-Cloud Complexity: In some situations, managing a hybrid or multi-cloud environment can be complex and may require additional tools and expertise to ensure seamless operation. This is another area we can help simplify for you.


Before deciding on a cloud migration strategy, it's essential to conduct a thorough assessment of your organisation's unique needs, constraints, and goals. A well-informed decision should consider these factors and carefully weigh the potential benefits against the challenges and limitations of cloud adoption. In some cases, a hybrid or multi-cloud approach may be a more suitable solution that combines the advantages of both cloud and on-premises infrastructure. 


At Stadia, we have a wealth of experience in planning and delivering cloud migrations, why not get in touch to discuss further?


Could we just migrate to the cloud “as-is”?

Ah, the Lift and Shift approach. We will talk about this in more detail in a moment. The answer is maybe. But it might not be the best approach for you. Let’s take a look at some of the established migration approaches, (you may have heard these referred to as "the Rs"):


Rehost (Lift and Shift): This method involves moving your existing applications and infrastructure to the cloud without making significant changes to their architecture. This approach is often used for quick migrations when you want to leverage cloud benefits like scalability and cost savings without rewriting the entire application. Common tools and services for rehosting include AWS VM Import/Export, Azure Migrate, and Google Compute Engine. These tools can vastly simplify/expedite such a migration.


Replatform (Lift, Tinker, and Shift): In this approach, you make some minimal modifications to your applications or infrastructure to optimise them for the cloud. You might update the underlying operating systems, databases, or application servers to take advantage of cloud-native features. It strikes a balance between quick migration and optimizing for the cloud.


Rearchitect (Rebuild): This method involves redesigning and rebuilding your applications to be cloud-native from the ground up.

You can take full advantage of cloud services and architectures, such as microservices, containers, and serverless computing.

While it offers maximum cloud benefits, it's also the most time-consuming and resource-intensive approach.


Refactor (Re-engineer): Refactoring means making significant code changes to adapt existing applications for the cloud. This could involve rewriting parts of your application. It's a good choice when you want to modernise legacy applications and take advantage of cloud capabilities.


Retire or Retain: During the migration process, evaluate each application and infrastructure component. Decide whether to retire (phase out) or retain (move to the cloud). While assessing your environment, you may discover unused applications or infrastructure that is no longer required. It rarely makes sense to migrate unnecessary components. Not all applications may be suitable for migration, and some may be replaced with cloud-native alternatives.

So, is it for us?

If you have read the list of potential benefits above and can see how these could relate to your business, then it is probably worthwhile exploring your options. Remember, cloud migrations are not a “one size fits all”, thorough assessment and planning is key to success. Migrating applications and infrastructure to the cloud is a complex process that requires careful planning, execution, and ongoing management.


The prospect of a cloud migration can seem daunting. That is where Stadia could help. We are experienced in planning and executing cloud migrations and would be more than happy to answer any questions you may have.
