"Then, of course, you also hope for cost reductions (...) by no longer having to maintain your own systems, you don't need infrastructure people anymore - or so you think." - Christopher Schmidt
The cloud offers benefits such as scalability and cost savings, but also challenges such as data migration and security, and the stable architecture is crucial when refactoring. A well-organized migration and team alignment will determine success. However, the software must also be suitable for the cloud and tested accordingly.
Christopher is a senior consultant at INNOQ Switzerland and has been working as a software engineer and architect for over 25 years. He has led numerous challenging and large-scale software projects to success in responsible roles. For many years, he has been a sought-after consultant and conference speaker with his leading knowledge of the latest cloud technologies, especially for migrating mission-critical solutions to the cloud.
Highlights in this episode:
- Christopher Schmid is an expert in the cloud
- We discuss how to survive a cloud migration
- Companies move to the cloud to reduce costs, increase flexibility and better reach global customers
- A migration requires careful planning in terms of infrastructure, architecture and organization
- The transition to the cloud brings new challenges, such as security issues and the need for regular updates
- A step-by-step approach, starting with Lift & Shift, followed by the adaptation of the architecture, is recommended
- Data migration poses a particular challenge, especially when large volumes of data are involved
- The introduction of a continuous delivery pipeline and automated tests is essential
- Organizational changes and the adjustment of roles within the company are necessary for the success of a cloud migration
- Tests must also take into account latencies and possible downtimes of services in the cloud

Successful cloud migration: focus on infrastructure, architecture & organization
TLDR: Cloud migration is a complex undertaking that goes far beyond technical aspects and involves both organizational and cultural challenges. The key to success lies in well thought-out planning, consideration of security, resilience and the continuous adaptation of processes.
The fascination of cloud technology
In today's fast-paced digital landscape, companies have felt a constant urge to move their infrastructure to the cloud. This movement is driven by the promise of cost savings, increased flexibility and scalability. In an inspiring conversation with Christopher Schmidt, an expert in cloud technology, we talked about the multi-faceted world of cloud migration. Our discussion took us through the many aspects and challenges that companies face in such an endeavor.
Why move to the cloud at all? The driving forces behind the migration
There is often more to the decision to migrate to the cloud than simply striving for technological progress. In addition to obvious benefits such as cost reduction and flexibility, it is also important to overcome hurdles such as security concerns or a lack of internal expertise. What is interesting here is Christopher's view that many of the problems that come to light in a cloud environment were often already present in traditional systems - but were swept under the carpet.
The three pillars of successful migration
A successful cloud migration rests on three main pillars: Infrastructure, architecture and organization. Each of these areas brings its own challenges. From migrating legacy systems to a modern cloud infrastructure, to dismantling monolithic systems and adapting organizational structures - all of this requires careful planning and execution. Of particular note is the need for cultural change within the company to make the transition as smooth as possible.
Best practices for a smooth migration
There is no one-size-fits-all solution on the road to the cloud. However, there are some best practices that can help companies avoid typical stumbling blocks. These include gradual migration using lift & shift approaches, refactoring existing systems to improve their architecture and implementing agile methodologies. There should also be a particular focus on establishing a continuous integration and deployment pipeline (CI/CD) in order to automate processes and optimize quality assurance measures.
The role of testing and quality management in cloud migration
One of the key elements for a successful migration is a robust test procedure. This involves not only functional testing of old systems, but also new challenges such as network latencies or temporary service outages in the cloud environment. Christopher emphasizes the need for resilience testing and comprehensive automation of all test processes as part of the CI/CD pipeline.
The human side of technology
A cloud migration is much more than a purely technical undertaking. It is a comprehensive transformation process that combines both technological and human aspects. The importance of a holistic approach involving all stakeholders - from developers to operations teams to company management - cannot be overemphasized.
