AWS re:Invent 2023 - A migration strategy for edge and on-premises workloads (HYB203)

Summary

Roshni Pari, leader of the Worldwide Specialist Organization for Hybrid and Edge at AWS, and Umar Chowdhury, PM Leader for Telco Networks, discuss migration strategies for on-premises and edge workloads.
Challenges faced by customers include latency-sensitive workloads, data residency, and local data processing requirements.
AWS addresses these challenges with a continuum of cloud services, including regions, local zones, outposts, and Snow family products.
Migration strategies include decomposing applications, identifying specific workload requirements, choosing between rehosting or refactoring, and using a distributed hybrid infrastructure.
Real-world examples from Athena Health and Absa Bank illustrate the migration process and benefits.
Umar Chowdhury discusses 5G network cloudification, challenges in current deployments, and AWS solutions for telco workloads.
Telefonica Germany's case study showcases the deployment of network functions using AWS regions and outposts.
The Migration Acceleration Program (MAP) is highlighted as a comprehensive framework for migration, covering assessment, mobilization, and migration/modernization phases.

Customers demand the ability to "build once and deploy anywhere," which AWS facilitates through its various services.
Data residency and latency requirements often necessitate a hybrid approach, combining cloud and on-premises solutions.
AWS's offerings, such as local zones and outposts, provide customers with the flexibility to meet specific latency and data residency needs while maintaining a consistent architecture.
The Strangler Fig pattern is a recommended approach for refactoring monolithic applications incrementally, minimizing risk and change.
The telco industry is undergoing a transformation with the migration of 5G network functions to the cloud, which AWS supports through its cloud continuum and managed services.
AWS's focus on sameness across its services ensures that customers can maintain a uniform architecture and automate deployments, regardless of whether workloads are in the cloud, on local zones, or on outposts.
The Migration Acceleration Program (MAP) is a key resource for customers embarking on migration journeys, providing tools, training, and support throughout the process.
