Cloud & Infrastructure

With its comprehensive knowledge of information systems, ALTEN provides you with its vision and expertise in your cloudification approach, offering advice on multi-Cloud integration, the optimisation of your On-Prem infrastructure, the development of your Cloud-Native applications, the development of a new operational model and the implementation of automation chains for private and public Clouds.
We are therefore in a position to work on: 

• Defining your Cloud journey  
  Advice, with a commitment to resources or results, on your IT system migration strategy.   
• The foundation of your infrastructure   
  Support in setting up Cloud governance, security and connectivity standards, and architecture patterns that will ensure your applications can be hosted on the target IT system.   
• Conducting a Cloud maturity audit   
  Review of existing systems and definition of a decision tree to model your target application architectures.   
• Studying business cases  
  Definition of an economic model combining the impact of implementing the target IS and managing the existing system.   
  Measurement of the integration effort in relation to operational savings.   

ALTEN recently supported one of its customers in building a complete ecosystem bringing together all information relating to its industry. The primary objective of this platform was to make available to all players in the sector the enormous amount of data previously confined to corporate or functional silos, and to enable everyone to have access to the right information at the right time.   

The arrival of the Cloud, whether private or public, is transforming our customers’ information systems on a massive scale. They are now concentrating their efforts on the migration and development of Cloud-Native services, expecting Cloud Providers to also take responsibility for the operational reliability of this new model. However, for the system to be fully reliable, centralised and resilient, it must also guarantee that applications can go into production.  

Site Reliability Engineering is an operational application of DevOps aimed at ensuring the reliability of applications. This approach, initiated by Google in its application release management, is based on the desire to combine rapid development with predictability in the behaviour of digital services.
 Implementing such an approach in a company offers a number of advantages, including:   

• Maintaining and improving application performance and availability. 
• Speeding up the delivery of updates and features by automating the most time-consuming tasks linked to testing, deployment and observability.  
• Strengthening collaboration between development and production teams. 
• Reducing expenditure on infrastructure and resource management.  

Ultimately, the SRE approach makes a major contribution to improving customer satisfaction by offering more reliable and efficient services. It therefore provides an interesting response to the need to transform our customers’ operating model, although this means adapting the approach to a traditional IT environment. To support its customers, ALTEN has therefore designed a specialised framework based on: 

• Feedback: Presentation of the SRE approach, its issues, its methodology and its automation tools through concrete examples of implementation in companies.  
• A maturity analysis: In-depth audit of your company’s SRE maturity level, whether in terms of its human, non-human, industrial or operational assets.  
  We are drawing up a clear matrix of the roles of each person within an organisation redesigned to integrate the SRE, by studying the toolchain, the procedures in place for developing and deploying digital services, and the operating processes. 
• An SRE pilot phase: Implementation of the SRE on a pilot application in order to identify the potential technical and structural levers or obstacles impacting its implementation.  
• Scaling up: On the basis of this initial experimentation, definition of a detailed action plan to integrate the SRE throughout your company, through organisational changes, dedicated training or the introduction of tools.  

In order to accelerate and strengthen its migration to the public cloud, a customer asked ALTEN to establish its new operational model and to define, industrialise and automate the new processes within its organisation.

Our experts therefore provided effective support to the in-house teams on technical issues relating to Move/Build to Cloud, automation, monitoring and alerting, as well as raising their awareness and training them in the DevOps culture.
