Objective

The core objective of our endeavour was to reimagine the very foundation of our client’s digital presence. Although the company had established its initial footing within the AWS ecosystem in Frankfurt, a profound decision emerged after extensive deliberation: to approach this venture with a fresh perspective. We opted for the clean slate approach, wiping away preconceived notions and existing configurations. A holistic vision drove this choice: a vision to craft an infrastructure that wasn’t merely an adaptation or an enhancement but a meticulously designed ecosystem that aligned seamlessly with the company’s future aspirations.

To embark on this transformative journey, we meticulously audited the company’s substantial on-premise network infrastructure. This audit served as a compass, guiding us through the labyrinth of existing systems, unravelling complexities, and illuminating areas of improvement. Armed with a comprehensive understanding of the company’s existing architecture and future aspirations, our mission crystallized: to design and implement an AWS network infrastructure in Frankfurt, the nearest region, that would not merely suffice for the present but stand as a resilient pillar for the next decade and beyond. The goal was not just about security, although paramount, but also about scalability, adaptability, and future-proofing. It was about constructing a digital ecosystem that could evolve organically, accommodating the company’s growth trajectory without necessitating major overhauls. Thus, the objective was not just a technical aspiration but a strategic commitment to pave the way for a future where the company’s digital infrastructure stood as an epitome of stability, security, and unwavering reliability for years to come.

What was done

By understanding their current configuration, we moved to the design. During the process we re-design the IP schema for the company, we didn’t want to have IP clashes or routing problems. The AWS VPC is quite a large network by default, and we carved it into much smaller networks. Most of our work was focused on the design 70-80%, we knew from the experience that diagrams, documentation will provide a much smoother transition during the transformation.

What was delivered within the scope:
– High-Level Design
– Low-Level Design
– Comprehensive IP schema for on-premise and cloud network
– Resilient uplink was added between on-premise and cloud infrastructure
– VPC has been carved into 200 (./24) networks, approximately 85% of them were Private, Restricted networks, and the remaining was Public/Internet-facing.
– We took advantage of Multiple Availability Zones and all the services were spread accordingly
– Applications were clearly divided into groups
– Security approach was very strict with dedicated Firewalls at IGW layer and within the network
– F5 dedicated load-balancing and security deployed
– Management block was created for the organisation in the Cloud
– Multi-Facto Authentication was enforced for all the employees
– Full testing conducted before handing it over to operations

Achievement

In a feat of seamless integration and meticulous deployment, we orchestrated the deployment and integration of a robust Cloud infrastructure tailored precisely to our client’s needs. Collaboration was at the heart of this endeavour, as we worked closely and harmoniously with the in-house IT team. Through collaborative efforts, we ensured the migration process was smooth and devoid of any creases, addressing every challenge that arose with agility and expertise. This intricate process unfolded over several weekends, a testament to our dedication to minimizing disruptions to the client’s ongoing operations.

A crucial phase of embedding and refinement ensued after the deployment, lasting an intensive month. During this period, we fine-tuned every element of the integrated Cloud infrastructure, ensuring it seamlessly merged with the existing IT ecosystem. This comprehensive embedding period was instrumental in optimizing performance, enhancing efficiency, and ensuring that every component operated cohesively.

Upon completing this meticulous deployment and the subsequent embedding period, the client delivered their confirmation: the project was not just a success but a resounding one. This affirmation is a testament to our collaborative spirit, technical prowess, and unwavering commitment to delivering solutions that meet and exceed our client’s expectations. With this achievement, we provided a secure and efficient Cloud infrastructure and fortified our clients’ confidence in their digital future, marking a significant milestone in our shared journey towards technological excellence.
