Cloud Assessment and Design expedites digital transformation at scale through rapid cloud adoption

Enterprises embarking on a cloud migration journey often recognize the benefits of cloud adoption such as increased scalability, faster time to market, and reduced migration efforts. However, they typically struggle to objectively analyze the cloud readiness of their complex IT landscape, choose among the various cloud platforms on offer, and craft a concrete roadmap supported by a viable business case which can be delivered in time.

Atos designs solutions for rapid cloud discovery and adoption. These cloud enablement solutions offer an innovative approach for rapid cloud assessment and design to help enterprises quickly assess, transform, develop, and design best-in-class cloud-native applications for public, private, or hybrid cloud. By implementing a "best fit" cloud discovery, assessment, and transformation strategy, enterprises can realize the full benefits of their cloud transformation journey in order to maintain their competitive edge, simplify their IT infrastructure, and optimize cost of operations.

Atos's Cloud Assessment and Design offering leverages the Atos Cloud Assessment Tool (ACAT) to transform the IT landscape in a customer's journey to cloud with a detailed approach and business use cases. ACAT is one of the critical tools used by Atos to assess application cloud readiness, target architecture blueprints, and total cost of ownership (TCO) as customers prepare to transfer their workloads to cloud architecture. ACAT includes Atos's prebuilt cloud accelerators to help customers to take full advantage of AWS cloud-native features and achieve their desired business objectives.

  • How it works
  • Atos's Cloud Assessment and Design offering is based on more than a decade of cloud expertise in developing innovative cloud solutions that help accelerate enterprise cloud transformations of on-premises application landscapes. Atos's methodology is powered by ACAT and ACAT's proven rule-based framework.

    Atos's engagements start with discovery and assessment of existing enterprise IT landscape, utilizing proven methodologies and easy integration with infrastructure discovery and third-party tools. An automated data-driven approach ensures data assimilation from various sources like configuration management database (CMDB) and IT service management (ITSM). Data is seamlessly fed into key accelerators including ACAT, which leverages Atos's patented algorithms to provide comprehensive dashboards with key application insights like cloud suitability model and cloud disposition for the AWS Cloud.

    Next, applications are planned and reimagined to align to a transformation roadmap. Atos creates the business case and application design to kick-start cloud adoption across the enterprise. Stakeholders are identified jointly with executive cloud sponsors of the customer. Subsequently sessions are conducted with enterprise architects and business and application owners.

    Based on ACAT cloud disposition recommendations and the application workloads, Atos leverages an Atos reference architecture repository consisting of an architecture metamodel and reference library to build target architecture blueprints. Atos's proven prebuilt accelerators and reusable AWS reference architectures help provide customers with deployment blueprints for multiple application workloads using the best-practice principles of the AWS Well-Architected Framework.

    The above solution building blocks are used as inputs to estimate and to provide the cost model to the customer. These solution building blocks are also leveraged in the Atos Cloud Migration Factory for creating move groups. Wave group planning is done using ACAT dashboards.

    A representative blueprint of Amazon Elastic Kubernetes Service (Amazon EKS) is available for reference in the architecture diagram section. This is the common repeatable pattern which is derived based on ACAT dispositions and containerized application workload. The above pattern is reusable and is customized while building the target architecture.
