I’m taking a brief break from my endeavours with GenAI to shed light on the landscape of cloud adoption across Europe, specifically highlighting the strategies that we at Parsectix have championed for years. Our operations span several countries in Europe, which can broadly be categorised into two packs: Northern Europe and Southern Europe. The narratives in these two regions offer contrasting insights.

In Northern Europe, organisations embarked on their cloud adoption journey some time ago and show no signs of slowing down. The region is replete with 'Digital Natives'—businesses that have been conceived in and scaled by the cloud. In addition, traditional or well-entrenched organisations have invested significant effort and resources over recent years to transition to the cloud and undergo a technological modernisation.

Conversely, Southern Europe has been a late adopter in embracing the cloud. The region is only now gearing up to harness the benefits of cloud technologies, with only a handful of companies making notable progress in their cloud endeavours.

Across Europe, many firms are yet to fully harness the capabilities of digital tools. A mere 26% have adopted pivotal technologies such as cloud computing, whilst AI stands at 25%, and big data at 14%.

As we dig deeper into this discourse, it's crucial to acquaint ourselves with the three major cloud migration pathways that have been instrumental in shaping this journey: Lift and Shift, Evolve, and Go Native. Each offers a unique approach and merits that cater to varied organisational needs and objectives.

Lift and Shift is commonly seen as the go-to method for those familiar with traditional infrastructure. In essence, it's about moving machine images directly to a cloud-based service.

While this approach was much-admired a decade ago for its simplicity, it doesn't fully utilise the capabilities of modern cloud platforms. It can also carry forward existing challenges. However, its speed and directness make it a preferred choice for those under time constraints, like an imminent datacentre closure or End Of Life hardware.

But it's worth noting a point from Gartner Research: "Most lift-and-shift migrations don't achieve the hoped-for business outcomes. It's vital to optimise for the cloud to truly benefit, rather than just making a direct transfer."

In short, Lift and Shift is quick and straightforward but may offer limited returns without further optimisation.

Evolve serves as a balanced approach, bridging the gap between Lift and Shift and a complete overhaul. While it remains rooted in the infrastructure, it may necessitate some developer adjustments to ensure smooth operations in the new cloud setting.

This strategy encompasses what industry giants label as ‘replatforming’, ‘revising’, and ‘refactoring’. One might opt for containerisation or lean towards PaaS alternatives such as Azure Web Apps or AWS’s Elastic Container Service. The 'everything-as-code' method can also be adopted, leading to redeployment within a newly designated VM-infrastructure, boasting advanced scaling and recovery features.

Choosing to evolve means refining operability at the infrastructure level. By leveraging the existing codebase in a more efficient cloud setting, there's no urgent need for extensive retraining or embracing new coding languages.

However, it’s wise to be cautious. Some features, which are present in traditional software versions, might be absent in cloud versions. Evolve offers a straightforward avenue to achieving moderate modernisation, bolstering both reliability and cost-effectiveness without the need for extensive changes. The use of containers, especially, alleviates worries over code portability and proves crucial for updating legacy systems. However, while the Evolve approach maintains a balance between risk and reward, it generally results in medium returns.

Embarking on a cloud-native journey presents high stakes. This method necessitates a union of comprehensive knowledge of core applications and an in-depth understanding of the intended cloud platform. Although it requires developers to swiftly acquaint themselves with new tech skills and methodologies, a well-implemented cloud-native approach promises significant returns.

Apps tailored for the cloud operate under the assumption that their underlying infrastructure might be unpredictable yet controllable. These applications are largely self-sufficient — able to autonomously scale and repair. They often employ ready-to-use features provided by the cloud provider, allowing much of the needed functionality to be consumed rather than hardcoded.

Opting for a cloud-native approach may appear costly initially but can be more cost-effective in the long run than a phased migration and subsequent redevelopment. However, this route can tether you closely to a specific vendor, making a future switch an overwhelming proposition that could involve abandoning any previous work.

Why might organisations opt for this approach? Those prioritising innovation typically view going cloud-native as essential. It stands out when the emphasis is on sustained agility, ongoing feature enhancement, and spotless scaling and performance. It also offers a prime chance to refactor and modernise applications, adopt microservices, or fade considerable technical debt. Although, inexperienced teams might inadvertently accumulate new technical debt.

Navigating the path to cloud adoption is indeed a balancing act. At Parsectix, we advocate for the "Go Native" strategy, recognising its ability to deliver unparalleled scalability, agility, and efficiency. However, we understand that a one-size-fits-all approach doesn't exist; for some, the "Evolve" strategy serves as a balanced, progressive route to cloud capabilities.

If you have already started your cloud jouerny, consider iterating again to fully embrace a "Go Native" approach. For those who just beginning, you have the golden opportunity to start directly with "Go Native," cutting through transitional complexities by focusing on your preferred cloud platform's intricacies.

The essence is to align your chosen cloud strategy with your organisation's broader goals. Doing so not only ensures technological progress but also strategic coherence, promising substantial returns on your software & infrastructure investments.
