Do you have an opinion about cross-cloud mobility and application portability? If yes, what about this is important to you? How do you intend to achieve this kind of cloud operating model? Is it about flexibility or more about a cloud-exit strategy? Just because we can, does it mean we should? Will it ever become a reality? These are just some of the answers I am looking for.
I am writing a book about this topic and looking for cloud architects and decision-makers who would like to sit down with me via Zoom or MS Teams to discuss the challenges of multi-cloud and how to achieve workload mobility or application/data portability. I just started interviewing chief architects, CTOs and cloud architects from VMware, partners, customers and public cloud providers (like Microsoft, AWS and Google) as part of my research.
The below questions led me to the book idea.
What is Cross-Cloud Mobility and Application Portability about?
Cross-cloud mobility refers to the ability of an organization to move its applications and workloads between different cloud computing environments. This is an important capability for organizations that want to take advantage of the benefits of using multiple cloud providers, such as access to a wider range of services and features, and the ability to negotiate better terms and pricing.
To achieve cross-cloud mobility, organizations need to use technologies and approaches that are compatible with multiple cloud environments. This often involves using open standards and APIs, as well as adopting a microservices architecture and containerization, which make it easier to move applications and workloads between different clouds.
Another key aspect of cross-cloud mobility is the ability to migrate data between different clouds without losing any of its quality or integrity. This requires the use of robust data migration tools and processes, as well as careful planning and testing to ensure that the migrated data is complete and accurate.
In addition to the technical challenges of achieving cross-cloud mobility, there are also organizational and business considerations. For example, organizations need to carefully evaluate their use of different cloud providers, and ensure that they have the necessary contracts and agreements in place to allow for the movement of applications and workloads between those providers.
Overall, cross-cloud mobility is an important capability for organizations that want to take advantage of the benefits of using multiple cloud providers. By using the right technologies and approaches, organizations can easily and securely move their applications (application portability) and workloads between different clouds, and take advantage of the flexibility and scalability of the cloud.
What is a Cloud-Exit Strategy?
A cloud-exit strategy is a plan for transitioning an organization’s applications and workloads away from a cloud computing environment. This can be necessary for a variety of reasons, such as when an organization wants to switch to a different cloud provider, when it wants to bring its applications and data back in-house, or when it simply no longer needs to use the cloud. A cloud-exit strategy typically includes several key components, such as:
- Identifying the specific applications and workloads that will be transitioned away from the cloud, and determining the timeline for the transition.
- Developing a plan for migrating the data and applications from the cloud to the new environment, including any necessary data migration tools and processes.
- Testing the migration process to ensure that it is successful and that the migrated applications and data are functioning properly.
- Implementing any necessary changes to the organization’s network and infrastructure to support the migrated applications and data.
- Ensuring that the organization has a clear understanding of the costs and risks associated with the transition, and that it has a plan in place to mitigate those risks.
By having a well-defined cloud-exit strategy, organizations can ensure that they are able to smoothly and successfully transition away from a cloud computing environment when the time comes.
What is a Cloud-Native Application?
A cloud-native application is a type of application that is designed to take advantage of the unique features and characteristics of cloud computing environments. This typically includes using scalable, distributed, and highly available components, as well as leveraging the underlying infrastructure of the cloud to deliver a highly performant and resilient application. Cloud-native applications are typically built using a microservices architecture, which allows for flexibility and scalability, and are often deployed using containers to make them portable across different cloud environments.
Does Cloud-Native mean an application needs to perform equally well on any cloud?
No, being cloud-native does not necessarily mean that an application will perform equally well on any cloud. While cloud-native applications are designed to be portable and scalable, the specific cloud environment in which they are deployed can still have a significant impact on their performance and behavior.
For example, some cloud providers may offer specific services or features that can be leveraged by a cloud-native application to improve its performance, while others may not. Additionally, the underlying infrastructure of different cloud environments can vary, which can affect the performance and availability of a cloud-native application. As a result, it is important for developers to carefully consider the specific cloud environment in which their cloud-native application will be deployed, and to optimize its performance for that environment.
How can you avoid a cloud lock-in?
A cloud lock-in refers to a situation where an organization becomes dependent on a particular cloud provider and is unable to easily switch to a different provider without incurring significant costs or disruptions. To avoid a cloud lock-in, organizations can take several steps, such as:
- Choosing a cloud provider that offers tools and services that make it easy to migrate to a different provider, such as data migration tools and APIs for integrating with other cloud services.
- Adopting a multi-cloud strategy, where the organization uses multiple cloud providers for different workloads or applications, rather than relying on a single provider.
- Ensuring that the organization’s applications and data are portable, by using open standards and technologies that are supported by multiple cloud providers.
- Regularly evaluating the organization’s use of cloud services and the contracts with its cloud provider, to ensure that it is getting the best value and flexibility.
- Developing a cloud governance strategy that includes processes and policies for managing the organization’s use of cloud services, and ensuring that they align with the organization’s overall business goals and objectives.
By taking these steps, organizations can avoid becoming overly dependent on a single cloud provider and maintain the flexibility to switch to a different provider if needed.
Multi-Cloud is very complex and has different layers like compute, storage, network, security, monitoring and observability, operations, and cost management. Add topics like open-source software, databases, Kubernetes, developer experience, and automation to the mix, then we will have most probably enough to discuss. 🙂
Looking forward to hearing from you!
