To migrate your applications to the Cloud and benefit from all its advantages, you will have to adapt or even rewrite them. Here are a few keys to managing this project and successfully "cloudifying" your applications.
The cloud has become essential. Companies are interested in it for the flexibility, cost optimisation, innovation and security it offers. In this context, you need to consider both the infrastructure and the applications themselves.
Moving your applications to the cloud does not have to be complex. Sometimes simple optimisations are enough. In other cases, a rewrite will be necessary.
What approach should you choose to port your applications to the cloud?
Cloudification implies a technical and business transformation.
From a technical point of view, a cloud application is characterised by its architecture, which must allow for scalability and the sharing of server resources. It must be oriented towards microservices, serverless, containers, etc.
From a business point of view, it is a question of taking advantage of the opportunities linked to cloud platforms: rapid launch of new services, use of integrated cloud services (chatbot, AI, Machine Learning, etc.).
We advocate a pragmatic approach, aligned with your constraints, your strategy and your resources. Only on the basis of this analysis can you make the right decisions and choose customised solutions and services.
A "cloudification" project in several phases
Upstream, your analysis must cover several elements:
- The application park
- The existing IT architecture and the security, performance and confidentiality aspects
- The objectives and complexity of your project
It is only after this analysis that you will be able to identify which applications should remain on premise and which ones should be moved to the cloud.
In this process, never lose sight of your needs and constraints (time, resources, budget, etc.). The choice of an adapted migration path will guarantee the success of the cloudification of your applications.
In the context of an application rewrite, we will try to measure the benefit of the Cloud by developing a key functionality in a Proof of Concept.
Then, in the development or adaptation of your application, particular attention must be paid to the management of the availability of your data, to the collaboration between the "cloudified" and "on premise" applications. The possibility of easily adding functionalities and adapting to new uses will also be essential.
The application adapted for the Cloud will have to be monitored for performance and resources used in order to be able to make adaptations according to the load.
Why migrate your applications in the cloud ?
The transition to the cloud, which is now widely accepted, provides the opportunity to gain a competitive advantage.
Time to market
The ability to deploy new applications or versions very quickly allows you to cope with the constant evolution of the market. Thanks to the self-service portal of the Azure or AWS platforms, resources are immediately available. The IT department can respond immediately to changing business needs.
The cloud offers you the opportunity to transform your services and the way you interact with your customers. You can deploy your applications around the world with a few clicks and enhance your users' experience wherever they are.
Security and availability
An application hosted in Microsoft Azure or AWS benefits from a level of security that is generally superior to traditional hosting. These platforms meet the highest standards and requirements of the market, including ISO27001 and the GDPR. In addition, their multiple data centres, global coverage and cross-site data replication solutions ensure business continuity after a disaster by minimising recovery time and the amount of data lost.
Avoid dedicated resources with a pay-per-use model where you only pay for what you use. You also reduce costs by combining all of the above benefits and by aligning your IT spending with changing business needs.
